毕业设计论文 设计（论文）题目： 汽车防盗报警系统 下 达 日 期： 2012 年 9 月 26 日 开 始 日 期： 2012 年 9 月 26 日 完 成 日 期： 2012 年 11 月 23 日 . 摘 要 随着电子技术的迅速发展，特别是大规模集成电路的出现，人类生活发生了根本性的变化。以单片机技术为核心的产品已走进了千家万户，汽车报警器的出现更是给人们的生活带来诸多方便，本文就实现了基于AT89C51单片机的汽车防盗报警的设计。 本设计以AT89C51单片机技术为核心，以各种硬件电路为基础，软件采用C语言进行编写，为了便于扩展和更改，采用模块化的程序设计方法，使程序设计的逻辑关系更加简洁明了，系统升级更加简单方便。利用单片机实现报警具有体积小、价格低、集成度高等突出优点,同时利用单片机来开发防盗系统能使系统易于操作，且花费较小，因而具有广泛的应用性。 本设计是为了解决传统汽车防盗方式的缺点和不足而开发一种崭新的集成传感、控制和报警三大功能模块的汽车防盗GSM 报警系统，通过安装该报警器在汽车中，当传感器收到汽车震动、移动信号时，以GSM 网络为信道，把报警信息通过短信通知用户，从而实现准确、实时的报警效果。 系统以振动传感器模块为载体用蜂鸣器进行报警，所以可以更好的保护汽车的安全。车主可以放心停放车了。 关键词：AT89C51,振动传感器,GSM报警系统 ABSTRACT With the rapid development of electronic technology, especially large-scale integrated circuits, to human life has undergone fundamental changes. With the single-chip technology as the core of products into the tens of thousands of households, the car alarm occurrence is to peoples lives a lot of convenience, in this paper, based on AT89C51 MCU automobile anti-theft alarm design. The design AT89C51 microcontroller as the core technology, with all kinds of hardware circuit software based, prepared using C language, in order to facilitate the expansion and change, modular programming methods, make the logic relation of designing program more concise, more simple and convenient system upgrade. Using single chip computer to realize the alarm has the advantages of small volume, low price, high integration advantages, at the same time, the use of single-chip microcomputer to the development of anti-theft system can make the system easy to operate, and much smaller, so it has wide application. This design is to solve the traditional automobile anti-theft method and the shortcomings and the development of a new integrated sensing, control and alarm functions of the three modules of automobile anti-theft alarm system through GSM, the alarm is arranged in the car, when the sensor receives the vehicle
