摘要

本防盗系统设计以MC68HC908GP32单片机为核心控制模块，使用红外线遥控模块实现远程遥控开启和关闭系统，采用振动传感器采集外部振动信号，利用声光报警模块发出声光报警。它的主要功能是当报警系统启动后，如果车子有振动，振动检测模块电路发出信号，经过单片机控制模块处理后，输出报警信号，再由报警模块实现报警。本防盗系统设计主要包括硬件设计和软件设计两大模块，其中，硬件系统主要包括四个部分：红外遥控模块、振动检测模块、单片机控制模块、声光报警模块。软件系统主要包括初始化模块、中断检测模块、报警控制等模块子程序。本防盗系统具有功能完善、工作稳定、成本较低等特点，具有一定的推广作用。

Abstract

The anti-theft system is designed by putting the M68HC908GP32 microcontroller as the core control module, using an infrared remote control module for remote control opening and closing system, using vibration sensors to collect external vibration signals, using sound and light alarm module warning. Its main function is when the alarm system activated, If the car has vibration, after single-chip control module processing the signal which coming from the vibration signal detection module circuits, putout alarm signal, and then alarming by the alarm module. The anti-theft system design includes hardware design and software design two modules, of which the hardware system mainly consists of four parts: Infrared remote control module, vibration detection module, single-chip control module, sound and light alarm module. Software system includes initialization module, interrupt detection module, alarm control module subprogram. The anti-theft system which is fully functional,stable job and cheap price and so on, so it has a certain role in the promotion.

Keywords: Microcontroller；vibration detection；alarm control
