Omijeh1Department of Electronic and Computer Engineering, University of Port Harcourt, Choba, Rivers State, Nigeria1’ABSTRACT :This project is based on the design and construction of an intruder detecting and alerting system. This was achieved using an AT89C52 microcontroller for the control of the other component, a SIM900-GSM module that communicates between the home owner phone and the PIR sensor (motion sensor). The interfacing between the GSM module and the microcontroller was achieved using an IC called MAX232 (this IC converts TTL voltage level (+5V) to RS232 voltage level (plus minus 7.5V) vice versa) and the microcontroller was programmed using assembly language. At the end of this project we were able to design and construct a device that is not only cheap but efficient. We overcome the problem of false alarm by using a PIR sensor (passive infrared: this sensor only respond to infrared emitted from the human body and animals) and after testing, the microcontroller responded to the information sent by the PIR sensor and in the occurrence of intrusion send an alert message to the home owner as well sounding an alarm to alert the neighbours using a buzzer.KEYWORDS; Intruder Detecting, G S M Module, P.I.R. SensorI.INTRODUCTION Security is a prime concern in our day-to-day life. Everyone wants to be as much secure as possible. In recent times the world has experienced an exponential increase in the rate of crime. Criminals break into houses on a daily basis around the world carting with huge amount of money and precious items. Sensitive and confidential documents, materials and equipment by corporation are constantly declared missing from where they are kept. So there is a need to provide a device that can detect unauthorized persons in an environment.In a network or a system, any kind of unauthorized or unapproved activities are called intrusions. An Intruder Detection System (IDS) is a collection of the tools, methods, and resources to help identify, assess, and report intrusions.Intrusion detection is typically one part of an overall protection system that is installed around a system or device and it is not a stand-alone protection measure (Ngad, 2008). In (Zhang et el, 2003), intrusion is defined as: “any set of actions that attempt to compromise the integrity, confidentiality, or availability of a resource” and intrusion prevention techniques (such as encryption, authentication, access control, secure routing, etc.) are presented as the first line of defense against intrusions.However, as in any kind of security system, intrusions cannot be totally prevented. The intrusion and compromise of a node leads to confidential information such as security keys being revealed to the intruders. This results in the failure of the preventive security mechanism. Therefore, IDSs are designed to reveal intrusions, before they can disclose the secured system resources. IDSs are always considered as a second wall of defense from the security point of view. IDSs are cyberspace equivalent of the burglar alarms that are being used in physical security systems today (Patcha and Park, 2007). As mentioned in (Zhang et el, 2003), the expected operational requirement of IDS s is given as: “low false positive rate, calculated as the percentage of normalcy variations detected as anomalies, and high true positive rate, calculated as the percentage of anomalies detected”.II.RELATED WORKS Considering the current global security environment, the importance of good physical security is difficult to ignore. Physical security services are becoming a private rather than public service i.e. individuals and organizations tend to hire private security firms and install security equipment and use the police as the back. According to the Bureau of Labor Statistics (2004), private security officers outnumber police officers by more than 2 to 1 in the United States of America. Recent reports suggest that this trend holds true for both daily security operations responding to terrorism, natural disasters. Physical security has seen less attention and it is primarily an applied field, it has no dedicated line of research. Instead, it is scattered through fields like engineering, computer science, chemistry and physics as well as social sciences such as criminology, sociology and psychology. The different types of existing security systems will be analyzed below. •Electrical LocksElectric locks come in many forms. The most basic is a Magnetic Lock (commonly called a mag lock). A large electro- magnet is mounted on the door frame and a corresponding armature is mounted on the door. When the magnet is powered and the door is closed, the armature is held fast to the magnet. Mag locks are simple to install and are very attack resistant. But mag locks are also problematic. Improperly installed or maintained mag locks have fallen on people. Also there is no mechanical free egress. In other words, one must unlock the mag lock to both enter and leave. This has caused fire marshals to impose strict codes on the use of mag locks and the access control practice in general. Other problems include a lag time in releasing as the collapsing magnetic field is not instantaneous. This lag time can cause a user to walk into the door. Finally, mag locks by design fail unlocked, that is if power is removed they unlock. This could be a problem where security is a prime concern.•Electric Strikes replace a standard strike mounted on the door frame and receive the latch and latch bolt. Electric strikes can be simple to install when they are designed for drop-in replacement of a standard strike. But some electric strikes require that the door frame be heavily modified. Electric strikes allow mechanical free egress: As a user leaves, he operates the lockset in the door, not the electric strike in the door frame. Electric strikes can also be either fail unlocked, as a mag lock, or the more secure fail locked. Electric strikes are easier to attack than a mag lock. It is simple to lever the door open at the strike. Often the there is an increased gap between the strike and the door latch. Latch guards are often used to cover this gap•Electric Mortise and Cylindrical Locks are drop in replacements for the door mounted mechanical locks. A hole must be drilled in the door for electric power wires. Also a power transfer hinge is used to get the power from the door frame to the door. Electric mortise and cylindrical locks allow mechanical free egress. Electric mortise and cylindrical locks can be either fail unlocked or fail locked.•Electrified Exit Hardware, sometimes called panic hardware or crash bars, are used in fire exit applications. The idea is that one simply pushes against the bar to open it, making it the easiest of mechanically free exit methods.Electrified exit hardware can be either fail unlocked or fail locked. A drawback of electrified exit hardware is their complexity which requires skill to install and maintenance to assure proper function.•Motor Operated Locks are used throughout Europe. A European motor operated lock has two modes, day mode where only the latch is electrically operated, and night mode where the more secure deadbolt is electrically operated ().USER AUTHENTICATION SYSTEMSWhen implemented with a digital access system, one of the following access systems or digital authentications systems can be with an electric lock. These however are only a few of the numerous authentication devices available.•Numerical Codes, Passwords and Passphrases: Perhaps the most prevalent form of electronic lock is that using a numerical code for authentication; the correct code must be entered in order for the lock to deactivate.Such locks typically provide a keypad, and some feature an audible response to each press. Combination lengths are usually between 4 and 6 digits long. A variation on this design involves the user entering the correctpassword or passphrase. A major hindrance however is the fact that users are capable of forgetting their codes.Forgetfulness is especially common in older people and this system will not be convenient for them. These codes are, in some cases, easy to crack.•Security Tokens: Another means of authenticating users is to require them to scan or "swipe" a security token such as a smart card or similar, or inter act a token with the lock. For example, some locks can access stored credentials on a personal digital assistant using infrared data transfer methods. However, just as in the case of an ATM card, the magnetic tape tends to wear off with time either resulting to time wasting in accessing a room or the inability of the user to access the room at all.•Biometrics: As biometrics become more and more prominent as a recognized means of positive identification, their use in security systems increases. Some new electronic locks take advantage of technologies such as fingerprint scanning, retinalscanning and iris scanning, and voiceprint identification to authenticate users. This is a very secure way of identifying a person’s identity but it is limited by the occurrence of an accident or disfiguration to the part of the body used for identification.III.MATERIALS AND METHODS The block diagram below shows the sections and the signal flow. The circuit diagram shows the different component required for the system to function properly.The Circuit AnalysisThe motion based security system is made up of the following stages;i.Power Supply Unitii.Input stage: the input stage comprises of;•Motion sensoriii.Control stage •Microcontrolleriv.Output stage •Buzzer•LCD Screen•Bulb•G S M moduleFig 3.1 The Block Diagram of the SystemA. POWER SUPPLY UNITFigure 3.2: Diagram of Power Supply UnitThe power supply serves as the main supply of electrical power to the system. The supply voltage is 220Vac that is step down by a 220Vac/12Vac, 500mA transformer. The 12V AC voltage is then rectified by a bridge rectifier to have a DC output. After the rectification process the remaining AC ripples are filtered off by a bypass capacitor. The output from the bypass capacitor is unregulated thereby causing a drastic voltage drop when a load is connected. To solve this problem an integrated IC chip voltage regulator is used to get fixed o utput.i. Analysis of Power Supply A 240/24V center tapped step– down transformer was used, to feed 24V to the circuit. Secondary voltage of transformer = 24V (Vγms ) the peak secondary voltage, V peak =√2 × Vγms ……3.1= √2 × 24 = 33.9VThe bridge rectifier diode will rectify the 24V from the secondary of the step down t ransformer.The full-wave bridge rectifier 5W001 was used because it have a peak inverse voltage of 50V and can pass a peak current of 2A which is suitable for our circuit design.V L (peαk ) = V (max ) − 2V d (oη) … … … … … … … … … 3.2Where V L(peak) is the peak to peak voltage of the loadV (max) is the maximum voltage of the alternating current V d(on) is the voltage drop across the bridge rectifier diode[33.9 − 2(0.7)] = 32.5VThe PIV rating of the diode to be used should be at least PIV = V (mαx ) − V D (oη) … … … … … … … … … 3.3 = 33.9 − 0.7= 33.2VTherefore the 50v PIV is far greater than this value 33.2v, thus making it suitable for this design. For a suitable filter capacitor value to be employed the following calculations was consideredVγ = Io /2fcWhere Vγ = γipple voltαge = 1.0Vf = fγequency = 50HzIo250mA Io = γegulαtoγ output cuγγent = 250mATherefore, C = 2fVγ = 2x50x1.0 = 2500 x 10-6 farad = 2500µf. Since 2500µf is not a standard value, 2200µf was used.2G N D2G N D2G N Dii. Voltage regulatorThree voltage regulators were used, two 7805 and 7812 both of them gives 5v and 12v respectively.iii. Light emitting diode (Indicator)A light emitting diode is connected in the circuit this will notify that there is power in the circuit. A resistor is connected in series with the light emitting diodes. The resistor limit the amount of current entering the light emitting diode. The value of the resistor is gotten from the calculation below.V = V = V d = V d + IRSupply voltageOperating voltage oflight emitting diode (LEDS ) I= R = V = V d = I = Allowable current through the LEDS Limiting current Re sistor 5v 2v 30mA(20mA )∴ R =V - V d I = 5 - 2 30mA=3 = 30 x 10-3 3 x 1000 30 R = 100ΩB. INPUT UNITThe input unit is made up of the motion sensor that senses if there is a movement in the restricted area the block diagram is shown below. .Fig 3.3 circuit diagram of the motion sensorThe motion sensor is used to detect the movement of a human body. It gives a low voltage when there is no motion, when there is motion it sends a 5volt, this will trigger the transistor. The transistor will send the zero voltage to the microcontroller. The transistor used in this circuit is used as a logic inverter. The voltage applied at the base is inverted at the collector terminal. When there is no intruder the motion sensor produces a low at its output terminal, the base of the transistor is connected to the output terminal of the motion sensor. The low signal switches off the transistor thereby preventing current from flowing via the resistor to the emitter. This is an open circuit condition, the voltage that will be gotten at the collector emitter junction is the maximum voltage applied at the collector terminal (5volt). This voltage is sent to the microcontroller.When the sensor senses motion it outputs a 5v for one second then goes back to zero, to search if there is any movement again. When the output is five volts the transistor is switched on making the collector voltage to have a zero voltage. The zero voltage notifies the microcontroller that an intruder has been detected. The motion sensor has a range of 6mD.CONTROL UNITThe control unit is the microcontroller (AT89c52). It is used to processes the security detecting system. The motion sensor is connected to the pin 1 of the microcontroller via the transistor logic inverter. When the microcontroller receives a low voltage from the input of the motion sensor it turns on the light, bulb, sends message to three individual and displays intruder detected on the liquid crystal display. The diagram of the control circuit is shown belowFrom figure 3.5, p1.0 is connected to the motion sensor via the logic inverter; p2 is connected to the liquid crystal display. Where p2.0, p2.1, p2.2 and p2.3 is connected to the data pins of the liquid crystal display and p2.5 and p2.7 is connected to the register select and enable of the liquid crystal display. P3.0 and P3.1 are the serial terminals of the microcontroller; it is connected to the GSM module via max232. The max232 is used to convert the voltage from the GSM to TTL voltage as well as converting TTL voltages to the acceptable voltage of the GSM module.The buzzer is connected to port 3.5 via a transistor when an intruder is detected; the microcontroller sends a 5volt to the base of the transistor. This switches the transistor and the buzzer is turn on.The light bulb is connected to relay which is connected to p3.6 of the microcontroller via the transistor, this illuminate the area of intrusion.Fig 3.4 control unitE.OUTPUT UNITThe output unit consists of;i.LCD Screenii.Buzzermpi. LCD ScreenThe LCD screen is used to display that an intruder has been detected; this is possible due to its data terminals and command register that the microcontroller is connected to. The buzzer sounds an alarm when an intruder is detected either from the infrared sensing system or the ultrasonic module.ii. BuzzerThe buzzer sounds an alarm when an intruder is detected from the motion detecting system.iii. LampThe lamp is connected to the microcontroller via a relay and transistor. When an intruder is detected the microcontroller switches on the bulb through the transistor and relay.iv. GSM moduleThe GSM module is used to sends message to three individual using AT commands. This is done by the microcontroller when an intruder is detected.F. CONSTRUCTION OF CIRCUIT AND ASSEMBLY OF COMPONENTSAfter designing the circuit in a software environment Proteus Version 7.8 and simulating it. The values of each component were obtained and ordered from the marketers and when they arrived construction began.The construction started with mounting of components on the Vero board; each component was tested before mounting and then soldered to the Vero board.The power supply unit was built first and the voltages from the voltage regulator were tested before going into the next stage. The control unit was soldered and tested. The output unit was soldered last and tested. Each stage is connected (joined) by a connecting wire or placed in the same row for continuity and tested before packaged with a plastic adaptable box. After packaging (casing) the prototype was tested and checked for any fault arising because of vibration and shaking owing to packaging.Figure 3.5: Circuit Diagram of the Motion Based Security System2G N D1 2 34 5 67 8 9 10 11 12 13 14V S S V D D V E ER S R W ED 0 D 1 D 2 D 3 D 4 D 5 D 6 D 72G N D2G N DIV.RESULTS AND DISCURTIONS Before using any component it is advisable to test them before soldering and also to test each stage of the project during construction. This approach provides us with an easy way to trace fault and easily correct them. The power supply unit was checked for proper voltage level from its output pins with a multi-meter. The motion sensor and GSM module were also tested, as well as the entire circuitry.

汽车防盗GSM报警系统设计
『摘要』本文首先简单介绍本公司研发的GSM 汽车防防盗报警系统的工作原理和设计过程。
接着详细介绍Freescale 半导体公司最新推出的新型加速度传感器的工作原理，并与汽车防盗GSM 报警器的结合的实际应用情况。
最后小结本设计使用加速度传感器的情况、存在的问题以及设计的改进思想。
1 引言随着中国经济的蓬勃发展，人们的生活水平日益提高，汽车的应用发展迅速，各类汽车的拥有量不断提高。
汽车的普及应用为人们的生活带来了方便，但同时汽车的使用也给人们提出了一大难题——汽车防盗。
汽车防盗成为了有车主们生活中的热门话题，也是汽车制造商关心的热点，目前各种汽车防盗方法和产品层出不穷。
但是，汽车防盗问题依旧没有完全解决，可谓道高一尺、魔高一丈。
汽车失窃案件还是时有发生，为人们的生活和财产带来很大的损失。
现有的方法有基于物理措施的，如防盗车门，防盗车窗；也有借助电子手段的，如电子门锁，电子报警器等等。
随着科技的发展，汽车是越来越安全了，但是窃车贼的手段也是越来越高明了。
防盗车窗还是能被打破，电子锁照样能被撬开，也就是汽车盗窃的物理途径不能被完全切断。
我们可以想象这样一个窃车的场景：汽车先被拖到一个偏僻的角落（异常移动），接着车窗或者车门被强力打开（异常的振动和震动），随后汽车就被盗走了。
于是我们想如何在这些异常情况发生时，能自动的被快速、准确的检测到，同时快速、有效的报警呢？本设计是为了解决传统汽车防盗方式的缺点和不足而开发一种崭新的集成传感、控制和报警三大功能模块的汽车防盗GSM 报警系统，通过安装该报警器在汽车中，当传感器收到汽车震动、移动信号时，以GSM 网络为信道，把报警信息通过短信/电话通知用户，从而实现准确、实时的报警效果。
2 汽车防盗GSM 报警器特点现行流行的汽车防盗器可以简单归纳为三大类，即：机械式防盗器、电子防盗器和网络防盗器，从盗车者破解的难度看，上述三类防盗器越往后科技含量越高，但价格也基本与科技含量成正比。

基于GPSGSM汽车防盗系统设计
基于GPSGSM汽车防盗系统设计汽车防盗系统已经成为现代社会中一项重要的装备。
本文将基于GPS和GSM技术，设计一种汽车防盗系统。
汽车防盗系统需要具备以下功能：远程追踪车辆、实时监测车辆状态、远程控制车辆等。
为了实现这些功能，我们将采用GPS和GSM技术。
首先，我们将在汽车中安装一个GPS装置。
这个装置将通过卫星定位系统，实时追踪车辆的位置。
通过与车载终端相连接，可以方便地获取车辆的GPS坐标。
接着，我们将引入GSM模块。
这个模块将提供数据传输功能。
当汽车发生防盗事件，系统可以通过GSM模块将相关信息发送到手机或者后台服务器。
同时，手机或者服务器也可以通过GSM模块进行远程控制汽车。
为了更好地保护汽车，在汽车进入停车模式后，系统会自动启动防盗模式。
当系统检测到汽车发生可疑动作时，例如车门被撬开、玻璃被砸碎等，系统会自动报警，并通过GSM模块发送报警信息。
同时，为了方便车主对汽车进行追踪和监控，我们可以设计一个手机APP。
通过这个APP，车主可以实时查看汽车的位置，并且可以设置电子围栏功能。
当汽车越出设定的范围时，系统会发送报警信息给车主。
此外，为了提高系统的可靠性，我们还可以引入其他技术。
例如，可以在车辆的关键部位安装传感器，用于检测车辆的倾斜、震动等，以提供更加准确的报警信息。
同时，还可以加装车辆跟踪装置，以防止遇到无法通过GPS定位的情况。
总之，基于GPS和GSM技术的汽车防盗系统可以更好地保护汽车的安全。
通过远程追踪汽车位置、实时监控车辆状态和远程控制汽车等功能，可以有效防止汽车被盗，并提高车主对汽车的安全感。
同时，通过引入其他技术，可以提高系统的可靠性和准确性。
在未来，随着技术的不断发展，汽车防盗系统将会越来越智能化，给车主带来更多的便利和安全。

在通信中，ＭＭＳ的收发方式采用现在通用的 ＷＡＰ方式。在该方式中，当ＭＭＳ终端发送ＭＭＳ信息 时，按照ＷＡＰ协议进行编码然后由ＧＰＲＳ网络传送到 ＷＡＰ网关：ＷＡＰ网关和ＭＭＳＣ之间按照ＨＴＹＰ协议进 行通信，从而把ＭＭＳ信息传至ＭＭＳＣ中，ＭＭＳＣ再进 行寻址、存储和转发。图３是基于ＷＡＰ实现的ＭＭＳ 处理流程。
实现ＧＲ４７与Ｉｎｔｅｍｅｔ的连接控制指令如下：
ＡＴ＋ＣＧＤＣＯＮＴ＝１，“ＩＰ”，“ＣＭＮＥＴ”；ＧＰＲＳ模块开通 ＴＣＰ／ＩＰ服务；反馈ＯＫ。 ＡＴ幸Ｅ２１ＰＡ＝Ｉ。１；ＧＰＲＳ模块分得固定虚拟ＩＰ地址；反 馈ＯＫ。 ＡＴ·Ｅ２ＩＰＯ＝１。“１０．０．０．１７２”，９２０１；连接ＭＭＳＣ；反馈
ＣＯＮＮＥＣＴ。

基于GPS／GSM的汽车智能防丢报警系统_0
基于GPS／GSM的汽车智能防丢报警系统【摘要】该文的主要创新体现于利用GSM手机模块的移动通信技术，与当今流行的GPS全球定位技术相结合，配合传统的单片机控制技术，完成了汽车防盗定位系统的设计，在实验室阶段的测试中获得了较理想的效果。
【关键词】GPS/GSM；汽车；智能防丢报警系统1.GPS定位数据的接收在默认情况下，GPS接收模块SIRFstarIII每秒输出一次定位数据，通常采用$GPRMC精简数据格式，该数据包含了目标的经度、纬度、速度（knot）、运动方向角、时间、年份、月份、时、分、秒、毫秒、日期等，定位数据是有效的还是无效的等重要信息。
语句格式如下：由于只需要知道位置信息，所以在实际应用中只用读取其中的至即可。
：代表UTC当地时间。
格式为“时分秒”，时、分、秒均为两位。
：代表工作状态。
“A”表示数据可用，“V”表示接收器报警，数据不可用。
：代表纬度数据。
格式为“度度分分.分分分分”。
：代表纬度半球，为“N”或“S”。
：代表经度数据。
格式为“度度分分.分分分分”。
：代表经度半球，为“E”或“W”。
：代表对地的速度。
范围为000.0～999.9节。
：代表对地航向。
范围为000.0～359.9，正北方为0，东方为90，南方为180，西方为270。
：代表UTC当地时间。
格式为“日日月月年年”。
：一般不适用。
软件在读取经纬度数据后，对当前位置进行分析，判断当前位置是否处于用户设定的安全区域。
判断方法是根据用户设置的活动中心点经纬度及被保护对象当前经纬度计算出是否超出预先设定的安全活动半径。
根据判断结果设置相应的标志。
其流程图如图1所示。
2.GSM的软件编程发送短信常用Text和PDU（Protocol-DataUnit，协议数据单元）模式。
使用Text模式收发短信代码简单，但是不能收发中文短信；而PDU模式不仅支持中文短信，也能发送英文短信。
系统中主要使用Text模式和PDU模式。
1）Text模式主要用来传送GPS信息。

CAN总线技术就是通过遍布车身的传感器，将汽车的各种行驶数据发送到“总线”上，在这个信息共享平台上，凡是需要这些数据的接收端都可以从“总线”上读取需要的信息，从而使汽车的各个系统协调运作、信息共享、保证车辆安全行驶、舒适和可靠。
同时我国的经济也在不断的飞速发展，汽车的数量也在不断增多，汽车被盗的数量也在不断的上升[1]，为了减少汽车被盗的机率，我们结合汽车CAN总线特点和GSM网络技术开发了一种新型防盗报警系统。
本防盗系统接入后，成为CAN总线汽车的一个节点，分析检测到的被盗信号传送到CAN总线上，由汽车ECU作出防盗的操作，例如切断油路和电路，本系统进行声光报警同时也通过GSM网向预存号码进行报警处理，整体结构图如图1所示。
本系统采用STM32F103为核心处理CPU，通过人体感应模块和振动传感器模块取样汽车现行状态，比如是否被盗被攻击或被拖动等参数。
无线遥控模块进行遥控设置汽车是否进入防盗模式，GSM模块发送汽车状况和接收车主指令，声光报警电路对被盗被攻汽车进行现声报警，微处理器通过CAN总线接口与汽车其他平台共享数据或者执行防盗的系列操作。
基于GSM的远程车载防盗报警系统设计
基于GSM的远程车载防盗报警系统设计随着监控范围的不断扩大，传统的有线监控报警已不能满足用户的需求。
然而，伴随着GSM 网络的发展，远程网络监控报警系统的硬件实现已成为可能，有望取代传统的仅由单机控制的监控报警系统。
本文针对目前的需求设计了一套基于GSM 网络的远程无线报警监控系统。
其基本思路是：将单片机与SIM300 通信模块通过串口连接，实现单片机与SIM300 之间的相互通信。
SIM300 模块设有SIM 卡插槽，可以实现与各种用户相互通信的功能。
系统接有震动、红外、声音等类型传感器，当汽车发生警情时，传感器将警情信号传送给单片机，经过单片机判断处理后，向用户发送报警短信，或者是直接拨打报警电话。
如果情况紧急，用户可以直接发送短信密码，由单片机控制继电器切断线路或者油路，使汽车停止运行，从而实现了远程控制，有效保证汽车的安全。
