摘要

本系统采用了红外传感器，它的制作简单、成本低，安装比较方便，而且防盗性能比较稳定，抗干扰能力强、灵敏度高、安全可靠。这种防盗器安装隐蔽，不易被盗贼发现。同时它的信号经过单片机系统处理后方便和PC机通信，便于多用户统一管理。

本设计主要包括硬件和软件设计两个部分。硬件部分包括单片机控制电路、红外主从机电路、驱动执行报警电路、LED控制电路等部分组成。处理器采用51系列单片机STC89C52。整个系统是在系统软件控制下工作的。软件部分可以划分为以下几个模块：数据采集、键盘控制、报警等子函数。

关键字：单片机；红外；主从及；电源设计

Abstract: Science and technology create people's life, science and technology lead people's lives, science and technology to enrich people's lives. Since the reform and

opening up, our side of the speed of technological development can be said to be dazzled by leaps and bounds, too busy to attend to all. With the development of science and technology, there is a great development of economy. In this thesis, we will design a very suitable for automobile anti-theft alarm system, we design the study to determine the use of pyroelectric infrared detectors, because of its relatively price is very good, anti-theft alarm effect, can be said to be high quality and inexpensive. Currently on the market mainly pressure triggered anti-theft alarm, electronic anti-theft alarm switch and pressure shading triggered burglar alarm and alarm, but this several common alarm have some shortcomings. The pyroelectric infrared sensor is used in this system, which is easy to produce, low cost, convenient installation, stable performance, strong anti-interference ability, high sensitivity, safety and reliability. This anti-theft device installation hidden, not easy to be found. At the same time its signal through the single-chip microcomputer system to facilitate the processing and PC communication, to facilitate the unified management of multi user.

This design mainly includes two parts of hardware and software design. The hardware part includes single chip microcomputer control circuit, infrared master / slave circuit, driving circuit, LED control circuit and so on. The processor uses 51 series single chip microcomputer STC89C52. The whole system is under the control of the system software. The software can be divided into the following modules: data acquisition, keyboard control, alarm and other functions.

Key words: single chip microcomputer; infrared; master slave; power supply design
