摘要
本文介绍了一种基于GSM 技术的汽车防盗报警系统，阐述了基于STC89 单片机的GSM 汽车报警器的硬件设计和软件设计。该系统利用GSM短信模块来发送接收用户的手机短信和来电,实现对汽车的实时监听和远程遥控。系统采用红外人体传感器，震动传感器，门传感器来探测汽车的状况, 当传感器检测到异常情况时,单片机控制GSM短信模块向用户发出报警信息。用户接收到报警信息后,可以做出及时的应对措施,达到了防盗的目的。该系统结构简单、功能实用,使用方便,通信成本低且能够有效地解决传统报警器存在的不足。

Abstract
This article describes a car anti-theft alarm system based on GSM technology,including the introduction of hardware design and software design of STC89 MCU-based GSM car alarm.Using GSM module to send and receive mobile phone messages and calls which users send,the system can achieve real-time monitoring and remote control of vehicles.The system uses three kinds of sensors to detect the state of the vehicle.When the sensors detect the presence of abnormal conditons,the MCU module which controls the GSM SMS will send alarm messages to users.When receiving a warning message,users can make a timely response which reaches the anti-theft purposes.The system has many advantages,such as simple structure,functional,practical and easy to use.In addition,it can effectively solve the shortcomings of trational alarm at lower communication costs.
