基于AT89S52单片机的汽车防盗报警系统设计 毕业论文
摘要
随着科学技术的进步，为对付不断升级的盗车的段，人们研制开发了不同方式构造的防盗器。
本设计以单片机AT89S52作为控制核心，从单片机最小系统设计、防人接近热释电检测电路的设计、玻璃防震、车身防击的振动检测电路的设计、防车门开启检测电路的设计、防接近驾驶座电路、汽车点火闭锁电路的设计、无线遥控电路及无线报警电路的设计等几个方面出发，详细研究和设计了汽车防盗报警器的各个局部容，设计了单片机及其外围电路，并结合一套经典的程序算法。给出了一套合理的汽车防盗报警器软硬件解决方案。

Abstract
With the scientific and technological progress, to bat the escalating car theft in the section, people developed different ways to structure the anti-theft device.
ThedesignMCU AT89S52 as thcontrol, fromthe microputer system design, anti-people close to the pyroelectric detection circuit design, glass vibration, the vibration of the body against attack detection circuit design, anti-detection circuit to open the door, anti-nearly driving Block circuit, car ignition locking circuit design, wireless remote control circuit and the design of wireless alarm circuit aspects of starting a detailed study and design of the vehicle anti-theft alarm in all parts of the design of the microcontroller and its peripheral circuits, bined with a set of the classic program algorithm. Given a reasonable car burglar alarm hardware and software solutions.
