摘要
分析现有汽车报警器的缺点,详细阐述了基于STC89C52单片机的GSM汽车报警系统的硬件和软件设计。该报警系统利用STC89系列单片机优良的性价比,使用支持GSM的SIM300C专用通信模块,具有远距离、无噪声污染和双向控制等特点,避免了现有普通报警器报警距离短、对环境产生噪音污染以及GPS报警器入网成本高,监控范围小,稳定性差等缺点。该报警系统可有效应用于各类机动车防盗报警。
In this paper, disadvantages of nowadays mobile alarming units are analyzed, a new design mobile alarming unit system based on GSM is introduced. The new alarming system uses STC89C52 series chips which provide high cost - performance, and SIM300C communication unit which supports GSM. It possesses the properties such as long distance available,no noise pollution, and bilateral controlling, avoiding the disadvantages such as short distance, pollution, noise of the common alarming system and high cost onnet,small domain supervision,low stability of GPS alarming system.
