PAGE I 毕业设计（论文）说明书 课题名称 基于GPS和GSM的汽车防盗系统设计 摘要 随着汽车数量的快速增加，汽车防盗产品的需求越来越大。目前市场上普遍使用的电子式汽车防盗产品作用范围小、可靠性低、误报率高且噪声污染大；而基于GPS全球定位系统和GSM公众网络的汽车防盗产品虽然其可靠性高，但是需要有监控中心的服务，需要缴纳入网费，造成车主防盗成本增高，导致在中低档轿车上的使用率还很低。针对这些问题，提出一种基于GPS和GSM的汽车防盗系统设计方案。系统以单片机为主控芯片，采用SIM908 GSM/GPRS/GPS一体化模块，利用GPS全球定位系统和GSM无线通信业务及短消息业务，设计实现了汽车的远程遥控、短信报警和定位追踪等功能，作用范围广，可靠性高且无噪声污染，并且不需要监控中心，降低了防盗成本。 关键词：汽车防盗系统；GSM；GPS；SIM908；单片机 Abstract With the rapid increase in the number of cars, more and more demand on automotive anti-theft products. On the market at present commonly used electronic automotive anti-theft products scope is small, low reliability, high rate of false positives and noise pollution; And based on GPS global positioning system (GPS) and GSM car alarm the public network product even though its high reliability, but need has the service of the monitoring center, need to pay it, cause the owner security costs increased, low-standard cars in use is still very low. To solve these problems, put forward a design scheme based on GPS and GSM car alarm system. System with the single chip processor as the master control chip, adopts SIM908 GSM/GPRS/GPS integration modules, using GPS global positioning systems and GSM wireless communication service and short message services, design and realize the remote control car, SMS alarm and location tracking, and other functions, wide scope, high reliability and no noise pollution, and does not require the monitoring center, reduce security costs.
