智能家居外文翻译外文文献英文文献智能家居技术
译文：智能家居技术链接您家的灯光，娱乐和安全系统的新的自动化家用技术。
智能家居，是一种可以通过识别具有不同生活习惯和感觉的住户来提供各种不同的智能服务。
而实现这样的功能其中最关键的问题之一就是如何确定住户的位置。
目前，研究工作只要集中于两种方法：终端方式和非终端方式。
终端方式需要一种住户随身携带的设备，而非终端方式则不需要这样的设备。
现在由于人人都想有一个方便，舒适，安全的居住环境，因此大家对于智能家居表现的越来越感兴趣。
一般来说，智能家居旨在提供合适的智能服务来积极促进住户更好的生活，比如家务劳动，娱乐，休息和睡眠。
因此，为了提高住户的便捷和安全，像家用电器，多媒体设备和互联网设备应通过家庭网络系统连接在一起。
并且它们应通过电视或个人数字助理（PDA）来控制或远程监控。
尤其要注意的是，作为一种提供高质量的智能服务，目标应集中于定位服务，同时考虑人为因素，比如住户的生活方式，健康状况和居住感受。
也就是说，如果智能家居能识别住户的生活方式或健康状况，那么家用电器应该能预见住户的需要，并能更主动的提供适合的智能服务。
例如，在一个被动的服务环境下，需要住户控制供热通风与空气调节系统（供暖，通风和空调），而智能家居将根据住户情况自动调节房间的温湿度。
智能家居或智能办公室的各种室内感应定位系统的已经研发到能够识别住户的位置。
一般来说，室内定位感应系统根据测量技术分为三种类型：三角测量，场景分析和接近方法。
三角测量法是通过多个已知点来计算位置距离。
运用三角测量法的例子包括Active Badges，Active Bats 和Easy Living，它们分别运用了红外传感器，超声波传感器和视觉传感器来实现的。
场景解析法是检测一个场景内的特定着眼点。
场景解析法的典型例子是使用直流磁力跟踪器的MotiveStar，和使用无线局域网络[LAN]标准IEEE 802,11的RADAR。
接近法则是以一组已知点中最接近的点近似作为定位点。

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 widevariety 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.

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 electronicinformation 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 andsecurity 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 theintelligent residential community. In particular, as people's living standards improve, people using home security alarm system equipmentwill 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 detecting various 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 mainlycomposed 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 ions 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 thatcan 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. Thetwo 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 preventfalse 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 longerreleases charge. Therefore, pyroelectric sensors cannot detect constantinfrared radiation. The infrared detector employs a photoelectric switch. The photoelectric switch (photoelectric sensor) is an abbreviation ofthe photoelectric proximity switch. It uses the object to block orreflect 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 thereceived 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 itsharm is very serious for the human body, especially infants, pregnant women, the elderly and chronic patients. Formaldehyde mainly exists onthe 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 issuitable 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 doesnot require power supply excitation. It only requires power duringsignal processing and display, so it is only a simple small battery cell.communication deviceThis system mainly adopts wireless communication methods, whichavoids 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 andthe 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. Thedetection 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 unit The 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 canmonitor the concentration of gas or natural gas in the home, discovergas leaks, and promptly report an alarm. Anti-theft function, when athief enters, immediately makes an alarm, and promptly informs thepolice 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 avoidthe loss; The system can be controlled by the remote controller, whichis 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 theAC220/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-upresistor 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 AVRseries microcontrollers are 5V, they are generally connected in series with 2K resistors.

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 theLCD12864 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-designedto 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 thepyroelectric 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 thesingle-chip microcomputer after being processed by a NAND gate. Whenonly 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 toexternal 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. The GSM module communicates with the user's mobile phone through the mobile phone network of the mobile phone, and the user can understand the security situation at home at any time. Each detection unit communicates with the main control unit through the wireless communication module and feeds back the detected information to the main control unit in time. System Communication Structure Diagram The GSM mobile network communication module uses the TC35 module. Its main features are wide coverage, low cost, reliable quality, and high security. It inherits the standard AT instruction set and RS232interface standard internally, which makes it easier 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. Communication module application circuit diagram SIM CARD is a mobile communication network user identification module. SIM CARD contains the user's user information and is an indispensable tool for communication with mobile phones. There are 6 pins corresponding to each other on the SIM card andthe card holder.

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.

People's living conditions have changed, Such as the living environment’s security and how comfortable they feel. So the intelligent residential building’s automatic emerge as the times require. Intelligent residential must have safety precautions, anti-theft alarm, fire alarm, toxic gas leakage automatic alarm and emergency call. It is able to implement remote control for the key equipment power. In recent years, with the progress of technology and economy, the electronic anti-theft alarm system has rapid development and a very wide application. Now it does not only apply in many important government departments, but also apply in the family.In-depth study on various alarm device, we have designed intelligent residential security alarm and remote control system on the basis of single chip computer. The system is based on 89C51 single chip computer, hasintelligent residential burglar alarm, emergency call alarm, fire alarm, toxic gas leakage automatic alarm and remote control. It is able to call the police hotline number. It is able to use voice alarm and show alarm occurred address. Users can set up and modify password for it. It can be recordable and voice suggestion and make use of the telephone to remote control. Calling when is not at home, it can use password to enter remote deployment and remote control the power of electronic appliance.The system makes use of communication equipment to realize multi-channel detection, scene alarm, emergency alarm, fire alarm and toxic gas leakage automatic alarm. It realizes remote voice alarm function through the automatic dial-up telephone. It directly parallels on the telephone lines, then may be used. Before used, user will be required to install the detection device in place where being watched by people. It must be set up alarm telephone number, recorded voice alarm. The alarm system has design innovation, multiply function, low cost, high reliability and so on.II.SYSTEM COMPONENTIntelligent residential security alarm and remote control system constitutes as shown following. The system is through telephone interface circuit and telephone network to link up. 89C51 single chip computer dominates by MT8880 Dual Tone Multi-frequency (DTMF) codec with the telephone network to exchange information. When the detection of dangerous situations, the dangerous situation coded signal transfer from the corresponding detection module through the antenna to master chip. The master chip brings the corresponding alarm information according to received signal. This part is to complete by the voice interface circuit, which uses ISD1420. After users call the number of system, users can control appliances according to sound by the voice interface circuit.The system components are made up of detecting circuit, wireless transmitter-receiver circuit, telephone interface, voice circuit, DTMF codeccircuit, telephone signal detection circuit and the main control circuit. Each module is described as follows:A.Detecting CircuitThe part circuit is as the detection part of the whole system, used to detect theft case, fire, toxic gas leakage and emergency call signals. Theftproof detection is to complete through pyroelectric infrared sensor. Sensors are installed on the balcony, windows and other place where thieves are easy to enter. The part circuit is at the ready state under normal circumstance. Sensors catch theft information when someone enters the scope of the surveillance. Then, wireless module will send the information to the 89C51 single chip computer. The detection of fire and toxic gas is to complete by the corresponding detection sensors, emergency call signal is sent from user hand-hold remote control.B.Wireless Transmitter-receiver CircuitThe transmitting and receiving circuit of the part makes use of CMOS manufacturing process produced by a low cost PT2262/PT2272 wireless remote control module. The operating frequency of it is 2 MHz and the communication distance of it is 100 meters above. Under normal circumstances, transmitting and receiving modules are in dormant status. The module is in non-dormant status when be in danger, then coded signal is transmitted. The receiving module has received high-frequency signal decode, generating interrupt signal at the same time.C.Telephone InterfaceHere shows telephone interface circuit. The phone lines normal is above 48V DC voltage and optocoupler is not conducting. When the phone lines are ringing signal which is 25±3V sine wave, Optocoupler is conducting, generating interrupted signal to the mainframe. The relay will be connected to J1,after mainframe detected ringing signal many times, then load resistor connected to a telephone line, that computer to simulate the extraction process. Since then, the system access DTMF signals from the TONE of coupled transformer, transmits voice signals from VOICE of coupled transformer. To disconnect the system, the system rings off.D.Voice CircuitThe voice circuit of system is used to generate alarm information and hint information. Using specialized voice integrated chip ISD1420, which provides 20 seconds recording time. Using subsection record, master audio recorder provides the starting address.E.DTMF Codec CircuitUsing MT8880 codec chips, to complete dial up function and decode passwords and control commands which are sent by users.F.Telephone Signal Detection CircuitThe telephone signal detection circuit uses pulse reshaping circuit design. The signal must be amplified by the signal amplifier circuit, then, to generatesquare wave signals to main control chip by comparator. Phone signals including dial tone, busy tone, call waiting tone, ring back tong, network busy tone relies on software to identify.G.The Main Control CircuitThe system adopt 89C51 chip as main control chip, the main controller call by detecting ring tone. Tone control circuits broadcast voice tone, to coordinate the competence of users who have complete remote control electrical appliances. On the other hand, Mainframe controls dial-up circuit given the preset number according to receiving alarm information.According to the alarm type of telephone sound, determine to call police or tell user the information. User may preset passwords, telephone number and record, and so on.III.SYSTEM SOFTWARE DESIGNSystem software is composed of main program, remote control subroutine, warning subroutine. In order for the system in idle time to enter a dormant mode, all the tasks are completed in interrupted service routine.A.Main program designHere shows main program flow chart. It mainly accomplishes initialize work, then the system enters a dormant mode. Whether there is password input or imported alarm. The results are processed accordingly. A method of determining whether to provide a user with access to the security system, enter a user password for verification by a program in a computing device. When valid user leaves, the main program waits for some time, automatically enters the maximum security state. The main program regular calls watchdog handling procedure, in order that the system is not normal reset.B.Remote Control ModulesWhen there is a ringing signal, remote control modules generate external interrupt. The number of the ring counts in interruption procedure, if the number is more than six times, the system hangs off, broadcasts hint tone to the telephone network. Then checking user passwords, if passwords are valid, user may control the work of electronic appliances. And the times of password input are limit. Check whether connection is overtime or not, hang up if it is overtime.C.Remote Alarm ModuleAn interrupt handler of remote alarm, also known as an interrupt service routine (ISR), is a callback subroutine in an operating system or device driver whose execution is triggered by the reception of an interrupt. When receivingmodule receives signals, main controller generates interruption, is out of dormant. Proceedings interrupted in this way shall continue from the point where they were interrupted, if making the interrupt trigger. For example, when the system withdraws from a defend position, the system ignores the security which has received alarm signals.After dialing has finished, we must judge by phone tone whether the call has been put through. If not, we want to repeat the dialing. We just hang up the telephone then repeat,otherwise, play alarm information to the other. The function is to complete by signal tone detection routine. System must identify signal tone, in order to identify the signal tone, we must know the characteristic of signal tone.IV.THE SYSTEM TESTING SHOULD MEET THE FOLLOWING REQUIREMENTa.Guard against theft and alarm system: Be able to dial preset telephone number and alarm telephone number, tell people by phone tone where the accident has happened.b.Emergency alarm: Be able to dial preset telephone number and emergency telephone number, tell people by phone tone where the accident has happened.c. Fire alarm and record hint: Be able to dial preset telephone number and fire alarm telephone number, tell people by phone tone where the accident has happened. And there is toxic gas leakage automatic alarm and emergency call.d. Be able to set up password and alarm telephone number, then modify theme. Remote control the power of appliancesV.THE EXPERIMENTAL RESULTSAccording to the program flow diagram with C or the assembly language compilation main program and music subroutine, carries on the debugging in the Keilc51 environment, will debug the good procedure usingthe programmer to solidify to MCU AT89C51. With the infrared sensor, the launch module, the receive module, the MCU, the acousto-optics alarm circuit welding on the PCB board according to the request, puts through the power source, the green power light is bright, indicated that the power source work is normal; When separation alert control switch, the alarm circuit does not work, therefore when some people intrude in the infrared launch area, also will not have the warning, when after closed alert control switch, the indicating lamp will be bright, indicates the alarm circuit in the work, when this time some people will intrude in the infrared launch area, will have the acousto-optic warning, namely the buzzer will send out music, red light emitter diode twinkle. The alert control master switch's function, causes the infrared burglar alarm's use to be more convenient, when the master wants to greet the visitor, may separate the alert control master switch, the visitor walks into the guard area not to report to the police; When the master wants to guard against theft, then closed alert control master switch, when has the unexpected visitor to intrude the guard zone time, will carry on the acousto-optic warning.VI.CONCLUSIONThis paper presents intelligent residential burglar alarm, emergency alarm, fire alarm, toxic gas leakage remote automatic sound alarm and remote control system, which is based on 89C51 single chip computer.
