摘要:随着我国经济的迅猛发展,人民生活水平日益提高,汽车已经开始进入千家万户。与此同时,汽车被盗案件频发的问题凸显。据了解,现在市面上流行有多种汽车防盗系统,但这些系统不同程度地存在误报率高、反应速度慢、成本过高等缺点,不太适合一般用户。针对以上问题,本系统利用当今广泛使用的GSM网络,设计基于GSM网络短信息的汽车防盗报警系统。本设计采用AT89C52单片机作为系统控制器、GSM模块选用SIM900A模块,如果有警情发生,振动处理模块采集信息,经单片机处理后输出控制信号,接着GSM通信模块发送报警信息到车主手机,同时启动声光报警,实现了一种可靠、高效、低成本的汽车防盗系统。本设计通过硬件和软件实现了短信报警功能。其原理简单、方便快捷,与传统的防盗方式相比有着独特的优势。74590

Abstract: With the rapid development of China's economy, the living standard of the people is increasing day by day, and the car has already begun to enter thousands of families。 At the same time, car theft cases frequently highlight the problem。 It is understood that there are a variety of popular car security system, but these systems in varying degrees, the existence of high false alarm rate, slow response, cost too high shortcomings, is not suitable for general users。 In view of the above question, this system uses the GSM network which is widely used nowadays, and designs the automobile security alarm system based on the GSM network short information。 This design uses AT89C52 microcontroller as controller, GSM module selection sim900a module。 If the alarm, vibration treatment information acquisition module, the microcontroller output control signal, and GSM communication module to send alarm information to the owner of the phone。 At the same time start the sound and light alarm, a reliable, efficient, low cost of automobile anti-theft system。 This design through the hardware and software to realize the SMS alarm function。 The principle is simple, convenient and quick, and has a unique advantage compared with the traditional way of security。
