摘 要
从世界上第一辆T型福特车被盗开始，偷车已成为现今社会里最常见的犯罪行为之一，这已成为一个严重的社会问题。随着汽车数量的增多，汽车防盗已经成了人们生活中的一个重要问题。随着电子技术的飞速发展，汽车防盗技术也朝着高度智能化、功能多样化发展。汽车防盗设备按其结构与功能可分四大类：机械式、电子式、芯片式和网络式，其中电子式是目前应用最为广泛的汽车防盗设备。本文设计的GSM汽车防盗系统属于网络式的防盗系统，也是目前市面上最先进，最可靠的防盗技术。
本文的设计是使用西门子公司的TC35模块作为通信核心模块，即报警信号通过控制单元的判断之后，再通过TC35模块以短信息的模式发送到车主所指定的手机上，这使车主可以在任何地方对自己的汽车进行监控。另外，它只需要车主自备一张进GSM网络的SIM卡即可进行通信，不需要加入一个专用网。它具有使用费用低，有效性能高的特点。
本文重点讨论课题的意义和设计方案的论证，以及设计制作的过程和调试优化过程。
关键词：汽车防盗 315M发射接收 AT指令 TC35模块
Abstract
From the time of the frist T-Ford car of the world been stolen,stoling cars has become one of the most common criminal act,which has been a serious problem.With the increasing number of cars,Car anti-stolen has become a critical problem in people's lives.According with the rapid development of electronic technology,the car anti-theft technology is developing towards a high degree of intelligence and functional diversification.The car anti-theft equipment ,according to their structure and function ,can be divided into four main categories:mechanical,electronic,chip-type and network.Among these categoties,electronic is one of the most widely used car anti-theft equipment methods.In this paper, the design of GSM car anti-theft alarm system is a network of anti-theft system,which is also the most advanced and reliable security technology on the market currently.
The designation of this paper use the Siemens's TC35 module as a core module of communication.That is the alarm signal transport through the judgement of the control unit，then throngh the TC35 module and used a short message sent to the mobile phones which the car owners has designated.This could allow the car owner to monitor their own car at any place.In addition, it can realize communication only requires the car owner prepare a SIM card which can connect to the GSM net by themselves instead of joining a private network.It has the character of low-cost and high-performance.
This article focuses on the meaning of discussing the topic , the demonstration of the design methods as well as the process of designation and debug optimization.
Key words：car anti-stolen 315M transmit and receive AT command TC35 module
