2、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 peoples life, science and technology lead peoples lives, science and technology to enrich peoples lives. Since the

3、 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

4、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

5、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 abi

6、lity, 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 desig

7、n 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 und

8、er 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 目 录 摘 要. 2 1 绪论. 4 1.1课题研究背景. 5 1.2 汽车防盗报警器的发展趋势. 6 1.3本文主要研究内容. 7 2 系统方案论证. 8 2.1 控制芯片的选择方案 . 8 2.1.1 STC89C52RC . 8 2.1.2 AVR单片机 . 8 2.1.3 FPGA . 9 2.2 主控制芯片的确定 . 10 3 系统硬件设计. 11 3.1 系统设计要求. 11 3.2 系统模块设计. 11 3.2.1中央控制模块. 11 3.2.2复位电路. 15 3.2.3时钟电路. 15 3.3 红外模块
