摘要随着时代的发展小轿车慢慢的成为每个家庭的必要交通设施，小汽车被偷的事件发生的概率大大的提升了，正常情况下有好多汽车是直接被别人偷走的，此外还有一些事件是小偷把别人的小轿车的车窗砸开偷取别人车里面的值钱物品，这样便给车的主人带来很大的损失，所以这次的设计就是建立在当下这些偷盗案件开发的一种小轿车远距离防盗报警系统。该系统将震动感应器和GSM系统结合在一起。当防盗系统被启动时，小轿车的振动感应器就会被打开，此时此刻就能知道车里面的振动情况，如果小轿车发生和被盗窃相像的振动之后，小轿车上面的振动感应器便会把振动信号传送到MCU开始数据处理，如果通过MCU处理完数据之后结果和小汽车被盗窃的特点相符合，此时MCU就会利用GSM网络给小轿车的主人打电话并且开启警鸣，车主接通电话后，可以监听车内发生的状况，并且可以通过语音系统给偷盗者发出语音警告。如果车主的小轿车最终还是被偷，但车主想要找回自己的汽车的时候，这时候就可以把GSM网络数据传给警察，这样就能成功的找回被盗窃的车辆。当小汽车被盗窃时它能够快速的反应，并且需要的成本比较低，并且具有相当大的实用价值。77258

 SCM remote vehicle anti-theft alarm system based on GSM

Abstract With the development of the era of car slowly become the necessary traffic facilities of every family, Car stolen incident probability greatly promoted, Under normal circumstances have a lot of cars are stolen by others directly, In addition to some events is the thief put someone else' s car broke down the window to steal others car valuables inside,This gave the owner of the car brings a lot of damage,So this design is based on the present development of the theft case a car anti-theft alarm system over a long distance。The system will be vibration sensors and GSM system together, Moreover the owner is carry mobile phone with you, So to the real-time status message to the owner of cars, So you can fully familiar with the car's security situation。 When the guard against theft system was started, The vibration of the car sensors will be opened, At this moment you can know the inside of the vehicle vibration, If the car and the vibration of the stolen alike,the car above the vibration sensor will sends the vibration signal to the MCU began to data processing, If through the MCU result after processing the data and the characteristics of the stolen car, The MCU will use the GSM network to call the owner of the car and open the police, Owner after the call, The status of the car to listeners, And can give you a voice warning system via voice。If the owner of the car will eventually be stolen, But the man wants to find his own car,At that time you can pass the GSM network data to the police,So you can successfully recovered the stolen vehicle。 When the car stolen it can quick response, Cost is low and needs, And has considerable practical value。
