各种高档家电产品和贵重物品为许多家庭所拥有。
然而一些不法分子也是越来越多。
这点就是看到了大部分人防盗意识还不够强.造成偷盗现象屡见不鲜。
现在很多小区都安装了智能报警系统，因而大大提高了小区的安全程度，报警器这时正为人们解决了不少问题.但是市场上的报警器大部分都是用于一些大公司财政机构。
价格高昂,一般人们难以接受。
所以本设计从价格低廉、技术性能稳定性商考虑设计一款报警器。
红外报警器正符合以上各种需要。
由于红外线是不见光，有很强的隐蔽性和保密性，因此在防盗、警戒等安保装置中得到了广泛的应用。
红外报警器大多数采用国外的先进技术,其功能也非常先进。
本设计需要一定的单片机，C语言，计算机，电子等丰富知识，在设计中可以将相关的专业知识融会贯通，并且需要动手实验，可以将自己的理论知识进一步深化，对于日后的工作起到了一个很好的开头作用。
1.1 防火防盗报警器概况报警器是一种以声音、光、气压等形式来提醒或警示应采取防护行动为防止或预防某事件发生所造成损失的电子产品。
人们生活水平随着社会的不断进步和科学技术、经济的不断发展得到很大的提高，对私有财产的保护意识在不断的增强，因而对防火防盗措施提出了新的要求。
它不仅要体积小、安装方便、功能较齐全等优点，而且要有很高的性价比。
1.1.1红外报警器技术的发展1、防盗报警主机与控制面板技术提升比如入侵探测，需要快速回应即时入侵事件，否则可能造成重大的损失。
因此，优秀的防盗报警产品，应该在性能与可靠性两方面，寻找平衡。
在探测技术上可以采用「红外XX」的双重或三重探测技术，尽量降低误报率。
此外，主机上若再加上嵌入式MCU或是微处理CPU技术，就可以让防盗报警主机在功能上提升到更多样化界面要求，在控制面板上，从本次测试产品上看，精致简化的控制操作与远端移移动界面的控制已是必然的趋势，加上不同的门禁控制界面，使得控制面板不再是一个死板的键盘而已。
防盗报警主机与控制面板也在防入侵防破坏的机制上有了大幅的改良，可看到密码锁盖板等设计的配合，还有外观材质结构着重抗暴与耐候的结构，这一切都在突显整体防盗报警系统的技术提升。
2、防盗报警系统发展人性化随着人们生活水准大幅提高，在实际生活，防盗报警系统的技术，也可以应用于提供个性化的医疗报警服务。
已有业者针对中国老人化的发展趋势，推出远端医疗看护回应系统解决方案。
透过防盗报警主机液晶萤幕、按键、呼叫键等功能特点，用户按键后，不需要透过电话，即可直接与保安服务中心或亲人对话。
该系统还可即时发现用户摔倒、活动等资讯，并有定时吃药提示等多种事件语音提醒功能。
另外，最新的防盗报警主机系统也可根据用户的不同需求，配备具备蓝芽技术的心电图监测仪、血糖仪、血压计、体重计等多种蓝芽医疗设备，可即时检测用户的血糖、心电图等生理状况，并透过报警控制主机，将用户的生理状况(心电图、血糖、血压)资讯，传送给远端医疗人员进行居家照护。
3、防盗报警系统的整合与应用整合是安防系统的一大发展趋势，防盗报警系统自然也不例外。
事实上，防盗报警系统与影像监控、门禁系统等其他安防子系统的整合，早非新鲜事，而近年来，由于其逐步将应用拓展到住宅、社区，因此也开始结合智慧家居，但这些仅是最简单、最基础的整合。
另外还可以做到如防盗报警与影像监控的连动，目前仅是利用硬体将前端探测器的输出介面，与影像监控的报警连动输入介面，连接起来，当出现异常情况时，透过预先设定的连动方式，执行影像报警连动实现影像回放、硬碟录影。
又如与软件平台的资讯整合，除硬体整合外，软件整合更是各防盗报警子系统间整合的重点。
在各系统整合中，目前的关键点是如何解决各系统之间资讯的互动及处理。
再过来就是最近的防盗报警整合要求必须要达到多种报警联网并存的方式，防盗报警联网有个容易混淆的含义，就是将报警控制器与控制中心的联网，跟报警探测器与控制器间的联网，混为一谈。
其实报警联网方式，包括有线、无线两种，如连线公安或以无线GSM电话通报，而报警探测器与控制主机间的联网，无线是专用无线，如红外线或Zigbee等并不是电信运营商所提供的无线平台。
这二者就重要性而言，报警控制器与控制中心的联网，才是系统整合的关键。
近年来，随着IP网路的盛行，不少报警控制器厂商也开始采用有线或无线的IP网路联网方式，但实际看到的连网应用由于使用环境的封闭性，透过TCP/IP的方式联网目前应用面尚未大幅成长。
1.1.2 红外报警器技术的现状现阶段防盗报警系统主要应用于侵入探测，亦即透过安装各类型的探测器(如主被动红外线、微波、门窗磁簧开关、紧急按钮、玻璃破碎探测器等)，按照预先设定的规则，检测被保护区域是否有非正常侵入；当发现有非正常侵入，报警控制器即进行语音声光的警示，同时显示警报点区域位置，联网的系统还会将报警资讯，透过手机、平板Pad、市内电话线、IP网路或以无线电信网路，通报用户或是监控管理中心。

外文翻译-- 基于STC单片机的红外遥控开关系统的设计
JSJ-1302计算机信息工程学院2013 届毕业设计(论文)外文阅读与翻译毕业设计题目基于STC单片机的红外遥控开关系统的设计外文翻译题目Decoding Infraed Remote Controls Using a PIC16C5X Microcontroller专业计算机信息科学与技术班级姓名学号指导教师职称介绍：家用电子工业已经应用红外遥控器控制电视机，录像机和有线电视很多年了。
同样的技术最近开始应用于工业应用以替代小键盘。
可以通过PIC16C5X译解大多数的红外信号。
这份说明书是描述如何破解的。
唯一用来译解IR信号的强制性硬件是红外接收仪。
它的两种类型的用法在这里都有说明。
两种模块类型都经常被用于家用电子工业。
第一种类型响应的已调制的红外信号大概为40KHz。
第二种响应未调制的红外脉冲并且有受限范围。
每种类型的硬件成本都不高于2美元。
此处描述了三种PIC16C5X应用程序，说明了如何用它们来创建一个算法使其能够破译任何遥控信号。
每种PIC16C5X应用程序表示在映射出一个预先存在的红外格式的一个步骤。
最终的应用程序是一个用来完全实现的示例的红外信号解码和解调的一种Teknika电视遥控器。
三个层次的红外线信号典型的红外信号遥控器有三层。
用于这些层的名字没有被标准化。
在这个应用程序中注意他们被称为“红外、调制和串行数据。
红外层是种发射方式。
红外线是一种因为波长太长以至于看不到的光。
虽然你不能看到红外光束,但它是光的一种形式,所以如果你不能看到目标设备,你就不能用红外信号控制它。
控制绕过拐角,通过不透明的材料、RF,通常使用超高频信号。
虽然这个应用程序注没有进一步提到RF,这里介绍的许多东西都是可以用作一个射频传输介质。
这个频率层爆出的红外信号通常是在频率调制32.75千赫和56.8千赫之间。
这样做是为了减少环境光的影响。
虽然考虑到这一层,但还是可选的。
如果不调整红外格式的输出,发送脉冲与未调整的红外线则相反。

Automatic fire alarm systemThe traditional electron safe alarm system mainly is through the sensor automatic detection, produces the alarm, sends out the alarm the scene or reports to the police through the special electric near distance, thus causes people's vigilance. Through many years research and the development, the present alarm apparatus may say is the class is multitudinous. As a result of the alarm apparatchik development and the social each domain anxious need, can application domain be more and more many, specially is overdevelops in the civil domain.In recent years, the infrared alarm apparatus already became reports to the police a domain hot spot,because it used was not the obviously infrared acquisition, Hereford the hiding to be good, characteristic and so on security. Infrared sensor is different according to the mechanism may divide into the light survey and the hot survey. The light acquisition sensor is uses the photon effect the acquisition aid. This kind of sensor speed of response quick, sensitive high, the examination characteristic is good, but needs cool, uses not conveniently. Moreover the component examination sensitivity and the infrared wave length concern. The hot acquisition is uses hotly releases the electricity effect the acquisition aid. After receives the goal the infrared misinterpretation increment, the temperature elevates causes the censorial certain physical quantities changes, through examination physical quantity change definite infrared emission. This kind of sensor works under the room temperature condition, examination sensitivity also very high, speed of response also very quick,moreover has nothing to do with with the infrared emission wavelength, may survey the power only to receive the background irradiation limit, the application is very convenient. This article designs atheist passive form hotly releases the electricity infrared acquisition aid. In the article mainly elaborated has hotly released electrician the principle, hotly releases content and so on Malayalam circuit which the electric detector the characteristic,the BISSAU signal processor, 555 timers composed. Finally designed completes has hotly released the electricity infrared detection alarm apparatus the hardware electric circuit.With the modern family use of fire, electricity consumption increases, the frequency of home fires is getting higher and higher. The family of fire, it is easy to fight does not occur promptly, the lack of fire-fighting equipment and the presence of panic-stricken people, to escape unfavorable factors, such as retardation, which eventually led to a significant loss of life and property. Explore the characteristics of the family of fire and fire prevention measures.For the prevention of domestic fires, reducing the fire losses have practical significance. In the modern urban family, because of lot of people do not understand common sense home security caused by fire, so that the happy family Geog underlined blink of an eye, and some lead to destruction, but the event of household fires, improper disposal, alarm delay is caused so that people should get to know more about the main causes of household fires, master to prevent the fire of knowledge and in case of fire to protect his or her own way, timely elimination of The United Kingdom each year more than 50000 families of serious fires, most of them fire casualties and significant loss of household assets, and some result in the neighbors, more heavy fire losses. Investigate the causes of fire in time, the vast majority of home fires happen parties said that the fire always feel that things are other people with their own far away, did not think this will happen even in the top of his head.Home fires are the main reason for negligent not to take timely preventive measures .In some of our large and medium-sized cities, almost every day family fires, fire prevention is so each family must always pay attention to. If your home based on the actual situation in advance to take simple fire prevention measures, a number of tragedies are entirely avoidable. Automaticfire alarm system is in order to inform the early detection of fire, and take effective measures to control and fight fires, and set in a building or other place of an automatic fire fac ilities, is that people with a powerful tool to fight the fire. Fire alarm system, fire detectors ge nerally, regional centralized alarm alarm and composition; also be required under the project with various fire-fighting facilities and communication devices linked to form a central contr ol system. From automatic alarm, automatic fire fighting, evacuation guidance, system proces s shows that, fire up a complete file management, fire control system. Fire detectors are fire d etection devices, as in the stage of fire will produce smoke with high temperature flame cells. The smoke, heat and light into electrical signals through the detector alarm or automatic fire e xtinguishing system to start fighting the fire in time. Area where the floor of alarm detector ca n send the signal into sound and light alarm, and fire on the screen showing the room number; while also monitoring the concentration of certain floors of alarm (if the monitor is located in the building fire Control Center) output signal or control automatic fire extinguishing system. Concentration of alarm signal is received by way of sound and light show, and the screen als o shows the specific fire floor and room number, the plane stopped taking the first alarm clock to record the timing, use of the machine-specific phones, but also quickly to the fire alarm togive directions and. In addition, you can control the fire extinguishing system or signal transm ission to the fire control room.Automatic fire alarm system is by the trigger devices, fire alarm, fire alarm devices and other auxiliary functions of the device with the composition of a button fire alarm system fire alarm system. It can fire early stages of burning smoke, heat and light radiation and other phy sical quantities, by temperature. Photographic and other smoke and fire detectors into electric al signals, transmitted to the fire alarm controller, and also shows the site of the fire, the fire re cord of the time. General fire alarm system and automatic sprinkler system, fire hydrant syste ms, smoke control systems, ventilation systems, air conditioning system, fire doors, fire shutte r, smoke screen and other related equipment interaction, automatically or manually issue com mands to start the corresponding device.(A) of the trigger devices in automatic fire alarm system, automatic or manual fire alarm signal devices generate called trigger conditions, including fire detectors and manual fire alar m button.

The monolithic microcomputer (be called the monolithic machine for short) is all playing very important role in a lot of fields such as being acting as very important role among them , automating in industrial control , data collect and instrument appearance. Have known well that the C51 series monolithic machine is core with 80, system has introduced whose structure principle and applied technique. Main content including monolithic machine ABC, structure and principle, instruction system, assembly language programming, monolithic machine inside parallel application, interruption technology, regular time counting technology, serial communicate by letter technology, system extended technology, A/D and D/A converter interface, monolithic machine apply and develop technology andso on knowledge. With the development of electron technology and computer art, the monolithic machine technology already becomes a distinctive branch of computer art , industry test control waits for a field to have got broad application in civil sum.The monolithic machine is had volume is small , the function is strong , reliability is tall , price hangs down , usage designs that convenient and systematic nimbly to wait for a characteristic. At present, monolithic machine navar is substituting tradition electronic control system with unparalleled speed. Technical ability that the engineers and technicians who studies the monolithic machine and grasps the person designing that the usage technology already becomes the present age college student and a few must prepare for, many enterprise requires that a great quantity is skilled urgently grasping the monolithic machine technology, can develop , apply the engineers and technicians who manages monolithic machine navar high level and defend together.

Simulations and figures such as the data being collected , being being to refer to the secondary sensor and other wait for measuring equipment is measured the process collecting information voluntarily in the element. The data collect system is certainly definition consumer measurement system coming true nimbly coming soft hardware product combining with computer-based measurement. It is the bridge that the computer and the outside physics world link. Various type signal collect difference difficult to exchange degree is very big. Noise also may bring about a few when reality is collected, inconvenient. Some basal principle needs to pay attention to when data collect, still has more actual problems needing to solve.System adopt capital pair of CPU control , the lead plane uses with being from the machine CPU the monolithic machine. Data being responsible for collecting seven roads from CPU, respond to the order that host CPU dispatches at the same time. Host CPU carries out a data handling , the data display , key-in, system give an alarm, pronunciation broadcasts the voltage value reporting passage. In host CPU and the communication from CPU, adopt the international standard RS232C interface, and use gleam to be short most (need only two. System has realized remote multi-path one kind of the pragmatic type having pronunciation broadcasting newspaper ,high-performance , high intelligence that pronunciation hint data collect system.Industry measurement system often must handle to coming from many signal source signals carrying out digitization coming to realize this handling, but adopt several kinds way. And then simulate multipath multiplex implement (MUX) making one's option in the entering signal coming from 8 simulation sensors, MUX makes a present of the output signal giving signal adjustment an amplifier , the signal adjusts an amplifier that the output signal is made a present of giving a modulus converter (ADC). But IC adopt integrated multipath multiplex implement and ADC at present commonly, also can a purchase the component parting for.System function 1, realizes the scene analog signal producing an implement , is to pass theself-restraint one sine wave generator , make use of sillster to change oscillating frequency,messenger frequency changes in 200 Hz ~ 2 kHz range, 1 v shifting last (200 Hz correspondence exporting 1 ~ 5 corresponding vs direct current pressure again after frequency voltage, 2 kHz are corresponding 5 vs) 2, road data collect implement data collect implement the first roads entering self-restraint 0 V ~ 5 V direct current pressure, 2nd ~ 7 roads import 5 V , 4 V , 3 V , 2 V , 1 V , 0 V direct current pressure coming from the direct-current source respectively (every road imports but not demanding accuracy from mark pressure implement creation). The analog signal changes every road respectively becoming 8 binary digit signals, in classics and/ the circuit varying string, use serial code to send in the transmission circuit.3, the master control implement collects and shows by the fact that the serial transmission circuitis in progress to every road data. Collect way collecting (namely 1 roads , 2 roads including cycling, ... 7 roads , 1 roads, ,) And choose acquisition (let choose a single file) two species way. Demonstrate the can demonstrate address at the same time and corresponding data of part. 4, the lead plane realizes pronunciation handling a hint and broadcasts every passage the voltage function , malfunction give an alarm function.Design that front preparation job develops person after receiving some item missions , need in general carrying out the following job first before the concrete design being in progress: 1, feasibility the purposesurveying feasibility surveying, is to analyse the possibility accomplishing this project. The job carrying out this aspect's, may consult home and abroad in connection with the data , looks at if somebody had carried out the similar job. If having , may analyse others then is the job how to carry out this aspect, what merits and demerits to have , what have to be to be worth drawing lessons; If not needing then doing surveying going a step further ,in priority now Ying Fang whether can realize this link, first, analyse , discuss the possibility coming true from being in progress theoretically, what be demanded if objective condition have (means , the instrument design that ,the fund waits if the environment , tests), and then be tied in wedlock reality , the problem to whether can set up a project to decide again. 2, the system overall plan designs design surveying the queen , being a system overall plan if being able to set up a project , will work next step in the feasibility being in progress.May consult this on one hand detailed , more concrete data on the priority Ying Fang technology degree of difficulty working in that project, now, the function consulting home and abroad the samekind product, brings forward the rational but feasible technology index , compile and compose out design specification , accomplish system overall plan design thereby according to the systematic different part and the function needing to come true.Design plan thin melt 3,ascertains soft hardware function ? ? once the overall plan decides down , job next step is to will owe a project thin melt , needs namely making clear that which part uses hardware to come to be completed , which part uses software to come to be completed. Therefore since the hardware structure and the software scheme may influence each other,aspect thinks from flexibility and General Availability facilitating the circuit structure , cost reduction , cutting down a fault rate , raising system , the function encouraging a software to be able to come true comes to be completed as far as possible from the software; But also should think that the essence replacing a hardware with the software being to reduce system real time nature , increases by handling the price being in progress being's, the software designs that cost , lead time will also increase by and , therefore, the systematic soft, hardware function assignment responds to according to the systematic request and reality but the rational arrangement , unification think. On the basis ascertaining the soft hardware function, designer's job starts the concrete problem dealing with one Yu right away, if the instrument volume and the master plan with the hardware realization scheme , software that the concrete technology index responds to relatively etc.Behind ascertaining personnel division of work , laying on job schedule , regulation the interface parameter, will must think that hardware , the software concre have designed a problem. ? ? is discussing this wants to emphasize an once too the front , here designing a problem concretely , that this several parts work above is essential, otherwise, the entirety may lead to a design plan changes , possibility leads to even a scheme to have no way to realize the dissipation bringing about manpower and material resources to a concrete application system design, To some extent , with regard to, this designs that De Lai talks , should pay attention to twice as much. A monolithic machine application system hardware design includes two most content:The monolithic machine system expansion part designs that first. It expands including that memory expanding and preparing an interface. Thatthe expansion , interface pointing to EPROM , EEPROM and RAM expand the memory expansion is to point to 8255 , 8155 , 8279 and other function component expansion. Two is every function module design. Controlling the function module , the man-machine conversation function module , exchanging the sincere message function module if the signal measures the function module , the signal and so on, demands to deploy ancillary equipment such as corresponding A/D , D/A , keyboard , display , printer according to system function. ascertain the circuital overall plan, needs the demonstration carrying out the detailed technology together. So-called circuital hardware population is designed , is to be to be to realize the electricity company line principle picture owing possessions needed by all fundamental project functions hardware. The first time contact this aspect job design personnel , sometimes be anxious to ask begin to make plate and debug in designing that the overall plan mounts more reluctant flower time , he urges a field excessively. This method not only no appropriate, and sometimes be an effect lose more than gain. Circuital every part is a rapid and intense relevance , is in harmony each other because of the hardware system comes to talk right away,any part of circuit's considers insufficiency , that the city brings the effect, hard to predict to effect hard to predict other part, makes the system entirety structure be destroyed gently then , weight is that population is big fruit the hand doing poorly done work over again , bringing about from this being to be imaginable lead to hardware. Therefore, we hope that the designer is not more stingy than on the overall plan the institute spends time. Judging from time, the good sometimes in initial scheme design stage , one design plan of hardware design most amount of work sometimes is able to have the effect getting twice the result with half the effort. Job next step is only capable to do proceeding as planned and without a hitch very much revise even if needing to do a part once the overall plan ascertains that down,a few being in progress also only here on the basis perfect the entirety working, but being able to not bring about doing poorly done work over again. When the overall plan in the hardware being in progress is designed, the what be related that to concrete circuit may use the job that others carries out in this respect for reference. Sometimes have certain rationality because of the circuit have debuged and testing process others (this also may exactly be experience location although these circuits are often no completely consistent with the circuit providing on the textbook and the handbook). Revise if carrying out a few combining with self design purpose here on the basis,be that one kind is simple and convenient , rapid method of work. The circuit needs self design certainly , a little bit , copying completely is not very possible. ? pi deceives to comfort the emergency quail saying the male plait fertilizer guaranteeing ? requiring the principle working to the person to have more incisive analysis and understand that , knowswhose applicability according to whose job mechanism , ascertains the possibility that the person transplants and the place needing to revise thereby; To the circuit that some critical Buddhist monks understand no completely,need careful analysis, And carry out an experiment before design first, to ascertain this circuital part correctness, job carrying out the ordeal, especially dummy load part , needing the aspect carrying out this more in aspect such as reliability and accuracy. That is makes the hardware design as far as possible rational , is based on experience, systematic wiring design should pay attention to several the following aspect: 1, chooses as far as possible standardizing , the modularized model is circuital, improve the success rate designing that and architectural flexibility; 2, goes down in allowable condition of condition , select and use a function as far as possible strong, high circuit of integration level or chip. Because of adopt this component to may replace some parts of circuit, not only component quantity , connector assembly and mutual company line fall off , messenger system reliability increases by, and cost sometimes is lower than using the circuit that the component realizes muchly to be than.，3, pays attention to choosing the strong , plentiful of marketplace source of goods component of General Availability, problem should pay attention to this aspect especially more to the occasion needing mass production. Whose merit is: Once certain, kind of component has no way to gain , also can use other component to substitute directly or to do slightly to the circuit changing the queen using other component to replace. 4, is in when population structure thinks to hardware system , same need to pay attention to the General Availability problem. To a more complicated system, the designer sometimes hopes with whose modularization, be that the centring bend controls an element , the halving piece importing an interface , exporting the interface , man-machine interface carries out a entire system designing, and then adopt certain edge taking over way that whose combination is become. The way in such circumstances, linking up appears very important right away , may select and use GPI way sometimes, if adopt STD highway structure , PC highway structure , GPIB highway structure etc.Because of the edge to these highways structure takes over the comparison applying at present，Many manufacturer already develops out being suitable to the interface board in these highways structure , exporting board , A/D board if importing board, and so on. Under necessary situation, select and use ready-made module board being the systematic part , be able to shorten lead time greatly , raise working efficiency although cost is partial to height a little bit. Certainly, in some special case and minor systematic occasion,the consumer must design an interface by self , define company line way. Need to pay attention to the interface agreement now, the module designer should observe that interface way one by one once the interface way ascertainsthat down. allowing some leeway , to prepare for future to revise, expanding on the basis satisfying the application system functional requirement. In fact, the circuit designs a success but not doing the condition that any revises is very few's, do poorly done work over again all round if being forced to be in progress in leeway , later stage designing that has not had any left for the first time probably because of to some extent little changing or expansion. Select and use 2764 the above chips for example , when carrying out ROM expansion, to the full, such escalates not only in the future going to the lavatory , the meeting also reduces cost; During the period of the expansion carrying out RAM, go to the lavatory for using system promotion or increasing memory, systematic RAM space should reserve enough location , do not insert a chip well even though designing one RAM socket more than normal,; During the period of the expansion carrying out the IO mouth, also should be given to a certain margin out, such has gone to the lavatory extremely to the passage or controlled member increasing a little measurement for a short time.中文单片机通过毕业设计，提高理论联系实际的解决实际问题的能力；提高对接口技术等相关硬件知识的深入理解；掌握8051的控制字的设置、工作方式、编程原理和微机接口方法。

It can detect home risk factors and prevent dangerous accidents.Keywords: home security alarm system; wireless communication; GSM1 Introduction1.1 Hidden dangers and detection in modern home lifeIn the modern home life, people cannot live without convenient living materials such as running water, electricity, and natural gas. However, they bring convenience to us and also increase the unsafe factors in the home life, leaking water pipes, accidental fires, gas leaks, etc. An accident can bring irreparable damage to the family. With the increasing population of the city and the increasing mobility of the population, the crime rate of theft and house robbery has been high for many years. Traditional anti-theft doors and windows have a certain preventive effect, and there are also many security risks. A wide variety of decoration materials, furniture, and decorative items provide us with convenience and beautify the home while alsocontaminating formaldehyde. Therefore, the safety of the home environment has received increasing attention in recent years. How to create a comfortable, healthy and safe home environment has become a hot topic of common concern. In recent years, electronic technology has been changing with each passing day, and communication technology is flourishing. Among them, the development of chip technology and sensor technology is particularly prominent, which provides new options for the solution of home security issues. The use of a home safety alarm device with a microcontroller and a sensor as its core enables the detection of various risk factors in the home, such as gas concentration, formaldehyde content, leakage of water pipes, and theft of rooms, etc. The system can perform remote alarms in a timely manner and notify the user Solve it.1.2 Selected topics and meaningWith the rapid development of science and technology and economic level, people's requirements for the home environment have evolved from the initial satisfaction of simple housing development to the emphasis on the human needs of residential housing. As a result, many safe, comfortable, fast, and convenient smart communities have emerged. where safety is the primary goal. In addition to human factors, the establishment of security systems is an indispensable and important measure for the realization of smart residential security.At present, there are many types of home security products on the market, which can be roughly divided into several relatively independent categories such as anti-theft alarms, video surveillance, and access control systems. Some products have fewer functions, and products with more comprehensive functions have relatively higher prices. Installation is complicated. In other words, there is an urgent need for a product that requires a price to be popular, strong functions, simple installation, easy use, reliable work, and low false alarm rate. Therefore, starting from the actual application, this article systematically elaborates that the use of the system does not need to change the power lines in the home. It has low cost, does not affect aesthetics, wireless communication, and is easy to use. It is suitable for general househo ld use. Home security is closely related to each of us. The use of home security alarm devicescan improve the quality of life of people and make life more secure and convenient. Because of the advantages of the system and the unmatched price/performance ratio of the 51 series microcontrollers, it will be used in future development. Has a broad market prospects and development potential.1.3 Research Status and Development Trends at Home and AbroadIn recent years, with the rapid development of electronic information technology, computer technology, communication technology and sensor technology, there are more and more products related to home security alarms. Domestic and foreign companies such as Siemens, Honeywell, Bosch, Shenzhen Yingmao and many other companies have developed a series of home security alarm products. They generally have wired or wireless communication functions to complete some alarm functions and have carried out Successful application. For example, Siemens' product portfolio includes general-purpose security and security solutions and services, including access control systems, intrusion detection, video surveillance systems, on-site service control centers, and emergency management systems. Thanks to the installation of the Siemens fire and voice evacuation system, the Jinmao Tower and the Grand Hyatt Shanghai, the world's top hotel, provide safe and comfortable working and living environments for thousands of people. It can be foreseen that the smart residential community will become the development trend of the construction industry in the future, and the home security alarm system will become an integral part of the intelligent residential community. In particular, as people's living standards improve, people using home security alarm system equipment will More and more, people's lives will be more comfortable and safer.2 home security alarm system overall design2.1 Overall Design Scheme of Home Security Alarm SystemThe design of this system is a new home security alarm system that integrates single-chip microcomputer control technology, sensor detection technology, and communication technology. The system is based on the single-chip microcomputer and consists of various detection units placed in different rooms and main control units responsible for decision-making. Each detection unit is responsible for detectingvarious conditions of the indoor environment, such as temperature, humidity, formaldehyde content, leaking water, etc., and then sending the collected data to the main control unit through wireless communication, and the main control unit makes a decision and issues a corresponding The instruction controls the operation of the system, thus realizing the automatic detection and automatic alarm of the indoor environment and maintaining the safety of the indoor environment. The hardware of the system consists of eight parts: main control unit, fire detection unit, water leakage detection unit, anti-theft detection unit, gas leak detection unit, formaldehyde content detection unit, wireless communication module, and GSM network communication module. Ensure the normal operation of the system. The circuit of the system is mainly composed of a power supply module, a microcontroller module, a sensor module, a wireless module, a display module, and an alarm module.2.2 main control unitThe main control unit, as the control center of the system, is responsible for receiving the information of each detection unit through the wireless module, processing the information, finding the alarm information to issue a corresponding alarm, and promptly notifying the user for processing. The main control unit can complete tasks such as GSM network SMS alarm, sound and light alarm, LED screen display, and keyboard control. The GSM short message module is used to send and receive short messages so as to monitor home security. A variety of sensors are used to collect home information, and information fusion technology is used to obtain more reliable alarm information. After receiving the alarm information, the owner responded to the SMS to control and handle the situation on the site, so as to ensure home security and theft prevention. The system is simple in structure, easy to install and debug, and easy to use.DetectorThe detector is used to detect various environmental information in the room. The environmental information is sent to the main control unit so that the main control unit can process the information in time according to the information. The sensor is the core component of the detector. According to the detection situation,sensors of different types and different principles constitute different detectors. The detectors involved in the system mainly include the following types:(1) Fire detectorFire detectors are mainly installed in the kitchen. It uses a combination of smoke sensors and temperature and humidity sensors. Smoke sensors mainly include ion smoke sensors and photoelectric smoke sensors. The system uses ion smoke sensors. The ionized smoke sensor contains an internal radiation source 241. The current and voltage of the ionization chamber inside and outside the sensor are stable under normal conditions. When a fire occurs, the ionization chamber ionizes positive and negative ions under the action of an electric field. The two io ns move toward the positive and negative poles, and the internal current and voltage change to generate an alarm signal. The temperature and humidity sensor can convert the temperature and humidity of the environment into analog signals. These analog signals are converted into digital signals that can be processed by the MCU under the action of their own processing chip. In the event of a fire, the temperature and humidity in the room will rise sharply within a short period of time. Comprehensive temperature and humidity conditions can prevent false alarms due to external interference from the smoke sensor.(2) Water leak detectorThe leak detector is mainly installed in the bathroom. Its working principle is mainly to use the conductive characteristics of water. The two probes of the detector are installed slightly higher than the ground, and are respectively connected to an I/O pin and GND pin of the microcontroller. When water leakage occurs, the water level is higher than the height of the probe. The two probes of the detector are turned on, and the level of the I/O pin of the microcontroller is set low to generate an alarm signal.(3) Theft detectorThe anti-theft detector is installed above the window. The detection part is mainly composed of pyroelectric and infrared sensors. When a gangster enters through the window, pyroelectric and infrared laser sensors can generate alarm signalsat the same time. The combination of the two sensors can prevent false alarms caused by small animals or accidents. An important component of a pyroelectric sensor is a piezoelectric ceramic dielectric that maintains its polarization after being poled, known as spontaneous polarization. Spontaneous polarization decreases with increasing temperature and drops to zero at the Curie point. Therefore, when this material is exposed to infrared radiation and the temperature rises, the surface charge will decrease, which corresponds to the release of a part of the charge and is therefore called pyroelectricity. The released charge can be converted to a voltage output via an amplifier, thereby generating an alarm signal. When radiation continues to act on the pyroelectric element to balance its surface charge, it no longer releases charge. Therefore, pyroelectric sensors cannot detect constant infrared radiation. The infrared detector employs a photoelectric switch. The photoelectric switch (photoelectric sensor) is an abbreviation of the photoelectric proximity switch. It uses the object to block or reflect the light beam and strobes the circuit by a synchronous circuit to detect the presence or absence of an object. The photoelectric switch converts the input current into an optical signal on the transmitter, and the receiver then detects the target object according to the received light intensity or presence or absence.(4) Gas leak detectorThe gas is mainly composed of hydrogen, methane, carbon monoxide, and ethylene, and the natural gas is mainly composed of methane, ethane, propane, and other components. It can be seen that in both gases, methane is an important component of them. By detecting the methane content, it can be determined whether gas or natural gas leaks occur. The methane sensor converts the information related to the methane concentration into analog signals. These analog signals can be converted into digital signals by the A/D chip and sent to the microcontroller. The microcontroller can obtain the indoor methane content according to the size of the digital data. Calculate the concentration of gas and natural gas so that detection and alarm can be achieved.(5) Formaldehyde detectorFormaldehyde is generally considered to be the number one killer of the indoorenvironment. Its release period is generally 3-15 years, and its harm is very serious for the human body, especially infants, pregnant women, the elderly and chronic patients. Formaldehyde mainly exists on the floor, decoration plates, furniture, carpets, paints, and glue. People can easily overlook its existence, but it can cause serious damage to people's health. The formaldehyde sensor uses the electrochemical formaldehyde gas sensor HCHO produced by Dart Sensor. This sensor is developed based on a breath alcohol sensor and is suitable for monitoring in most environments (-20°C~+50°C) (for special applications, it can be used at higher temperatures). This sensor is simple in design, with few components and its cost is reduced. It does not require power supply excitation. It only requires power during signal processing and display, so it is only a simple small battery cell.communication deviceThis system mainly adopts wireless communication methods, which avoids complicated laying of lines and is both beautiful and convenient. The main control unit and each subunit communicate with the wireless module 24L01. The effective range is 60 meters, which fully meets the needs of home use. The communication between the main control unit and the user adopts the GSM (mobile phone network) method. The alarm system can send the information in the home to the user as a short message. The user can also control the running of the home system by sending an SMS.Home Security Alarm System Functions and Working PrinciplesThe main control unit of the system can be placed in the living room, and the detection unit can be installed in different rooms of the house. For example, the fire detection unit is installed in the kitchen, the leak detection unit may be installed in the toilet, the anti-theft alarm detection unit is installed above the door and window, the gas leak detection unit is installed in the kitchen, and the formaldehyde content detection unit is placed in the living room or the bedroom. The detection unit placed in different locations sends information to the main control unit in real time through the wireless device. Once a fire, leaking water pipe, burglary, or gas leak occurs, the main control unit will immediately receive an alarm signal. Then the main control unitThe unit will judge and process the alarm signal, get the alarm type, make an audible and visual alarm, and notify the user through the GSM network. The home security alarm system has six main functions: Mobile phone network intelligent alarm. When an unexpected situation in the home is detected, an alarm is sent through a text message. It can monitor the concentration of gas or natural gas in the home, discover gas leaks, and promptly report an alarm. Anti-theft function, when a thief enters, immediately makes an alarm, and promptly informs the police and the household head; Intelligent fire alarm, immediately when the fire occurs in the home, to alarm, to reduce the loss of property; Intelligent waterproof detection function, found a leak in the home, timely closure of the main valve, And notify the owner by SMS to avoid the loss; The system can be controlled by the remote controller, which is easy to use and easy to operate.3 Hardware Design of Home Security Alarm System3.1 Design of the main control unitThe main controller consists of power supply, GSM communication module, wireless communication module, display device, button, and remote controller. The structure is shown in the figure.Figure 3 main control unit system diagram Power section uses the AC220/DC5V power supply module, after the power supply voltage transformer voltage regulator, and finally get a stable 5V voltage to the microcontroller and other electrical equipment.

When connecting with P0 port of 51 series single-chip microcomputer, it needs to add 10K pull-up resistor and it is not necessary to connect with other ports. For other series of microcontrollers, if it is 5V, please refer to the output current of the IO of this series of microcontrollers. If it exceeds 10mA, series resistor divider is required. If it is 3. 3V, it can be directly connected to the IO line of the RF2401 module. For example, if A VR series microcontrollers are 5V, they are generally connected in series with 2K resistors. The keypad is used to set the basic parameters of the main control unit. It can also set the parameters through theSAA3010T remote control. The remote control receiver uses HS0038.

Its operation method is the same as that of an ordinary TV remote controller, and the operation is simple and easy to use.3.2 Design of fire detection unitThe fire alarm unit is composed of a smoke sensor and a temperature and humidity sensor. The increase of the temperature and humidity sensor can enhance the reliability of the alarm and reduce the occurrence of false alarms. The composition of the fire alarm unit is shown in Figure 8. Fig. 8 System diagram of fire detection unit The smoke sensor converts the collected smoke concentration into an analog signal. After the A/D chip, the analog signal is converted into a digital signal and sent to the microcontroller. Temperature and humidity sensor The DH11 can send temperature and humidity in digital form to the microcontroller, so the signal does not have to be processed. The MCU sends the received information to the master control unit through the wireless communication module 24L01. The type of smoke sensor used in the system is MQ-2. The gas sensitive material used by MQ-2 is tin dioxide (SnO2) with low conductivity in clean air, and its sensitivity to smoke is very high.3.3 Design of leak detection unitThe unit's design mainly utilizes the conductive properties of water. There are two detection probes connected to the microcontroller, which are connected to the I/O pin and the GND pin of the microcontroller. When in use, put the two probes above the bathroom floor. When there is water leakage, the toilet will produce water. The two probes of the detector are connected to the stagnant water. The preset high-level I/O pins are set low. , Generate an alarm signal, the microcontroller then sends the alarm signal to the main control unit through the wireless communication module, thus completing the entire alarm process. The specific structure of the alarm unit is shown in Figure 11.3.4 Design of Gas Leak Detection UnitThe gas leak detection unit is mainly composed of a methane content displayliquid crystal, a methane sensor, a wireless communication module, and a buzzer alarm. The structure is shown in FIG. Figure 12 shows the gas leakage detection unit system. Among them, the liquid crystal display is a 5110 liquid crystal display. Its features are: Cost-effective, LCD1602 can display 32 characters, and Nokia5110 can display 15 Chinese characters, 30 characters, Nokia5110 bare screen only 8. 8 yuan, LCD1602 generally about 15 yuan, LCD12864 generally 50 to 70 yuan; interface is simple, only four I / O lines can drive, LCD1602 need 11 I / O lines, LCD12864 need 12 root. The speed is 20 times that of the LCD12864 and 40 times that of the LCD1602. The model selected for the methane sensor is GJ4. Its output is analog and needs to be sent to the microcontroller via A/D conversion. Its use is similar to the smoke sensor.3.5 Design of formaldehyde monitoring unitFormaldehyde detection unit is mainly composed of formaldehyde sensor, operational amplifier, wireless communication module and sound and light alarm. The formaldehyde sensor converts the formaldehyde concentration into electrical signals. The signal is processed by the operational amplifier and then input to the single-chip microcomputer. The single-chip microcomputer judges the signal and sends the formaldehyde content signal to the main control unit through the wireless communication module. The sensor contains a conventional two-electrode fuel cell sensor. The working electrode discharges electrons to the counter electrode through an external circuit and is consumed at the counting electrode end with the reduction of oxygen. The internal circuit is realized by the ion current in the electrolyte. Well-designed to facilitate the growth of electrolyte. The rise and fall of the electrolyte varies with the changes in ambient temperature and humidity, but the normal operation will not affect the calibration value. The specific circuit shown in Figure.3.6 Design of anti-theft alarm unitThe anti-theft alarm unit is a double detector consisting of a pyroelectric sensor and an infrared sensor. Compared with conventional pyroelectric or infrared single sensor systems, Shuangjian detectors have significantly reduced their false alarm rates.When the Shuangjian detector works, the two signals of the pyroelectric sensor and the infrared sensor are processed by the NAND gate and sent to the SCM. When only two sensors respond at the same time, the detector sends an alarm signal to the microcontroller, otherwise no alarm signal is generated. In addition, when designing, Fresnel lens is added to the pyroelectric sensor, and the principle diagram of false alarms that can reduce the external interference signal by changing the lens division method is shown in Fig.16. Fig. 16 System diagram of the anti-theft alarm unit When the double-detection detector works, the pyroelectric sensor and the infrared sensor signal are sent to the single-chip microcomputer after being processed by a NAND gate. When only two sensors respond at the same time, the detector sends an alarm signal to the microcontroller, otherwise no alarm signal is generated. In addition, Fresnel lens is added to the pyroelectric sensor during design. By changing the lens segmentation mode, false alarms due to external interference signals can be reduced. 3.7 Design of Communication SectionThe communication part of this system is mainly composed of GSM mobile network communication module and 24L01 wireless communication module.

It inherits the standard A T instruction set and RS232 interface standard internally, which makes it easie r for the microcontroller system to control it. It reduces the design of external circuits and simplifies the programming of the program. The hardware circuit is not complicated, but there are many modules used, which increases the complexity of programming and the difficulty of debugging. Therefore, it is necessary to debug each module individually after being debugged by the single chip microcomputer.
