基于单片机的汽车智能防盗系统设计

Design of Intelligent Car Anti-Theft System on MCU

运用单片机能控制TC35i模块收发短信的特点,设计汽车智能电子防盗系统。该防盗系统能够在汽车被盗时第一时间发送短信给车主,然后自动拨打车主的手机号码让车主监听汽车周围的环境声音。同时,在汽车发动机汽油喷射系统上安装常闭触点继电器,车主可以通过手机短信控制继电器开关,使汽油喷射系统根据车主的意愿供油与断油,从而达到防盗功能。

In the article, the function that the single-chip unit （MCU） can control TC35i module to send and receive test messages is used to design the intelligent car anti-theft system. The anti-theft system can immediately send the test messages to the car owner when the car is stolen and then automatically dial the telephone number of the car owner to let him monitor the sound surrounding the car. At the same time, a normally-closed relay is installed in the fuel injection system of the car engine, through which the car owner can send the mobile phone messages to control the relay switch and allow the fuel injection system to provide or cut off the fuel, achieving the anti-theft function.
