Based on Single-chip Microcomputer multi-function car alarm
Abstract
This article introduced based on Single-chip Microcomputer multi- function car alarm. System uses various sensors to test the theft situation and working circumstance of Automotive various parts equipment, automobile anti-thief alarm's opening and with closure through remote control. When automobile's anti-thief alarm is opening, if the automobile alarm had discovered some people steal the automobile, the Single-chip Microcomputer circuit control sound alarm circuit sends forth the warning at once, simultaneously Single-chip Microcomputer controls the wireless signal circuit to sends forth the alarm, simultaneously shuts off ignition system's power source. When the vehicle driving. Make use of sensor versus the auto plant working condition proceed automatic measurement, when the auto plant has abnormally work, the Single-chip Microcomputer has proceed respectively alarm according to the signal of the sensor, reminds the driver to carry on the processing, avoids happen the accident.

摘要
本文介绍了基于单片机的汽车多功能报警器的设计。系统利用各种传感器对 警情和汽车各部分设备进ຫໍສະໝຸດ Baidu检测,通过遥控实现汽车防盗报警设防和撤防。当报 警器处于设防状态时,若警情采集电路采集到警情信号时,AT89S51 立即接通报 警驱动电路实现声光报警,同时 AT89S51 通过无线信号发射电路发给车主报警 信号,并切断点火系统的电源。车辆行驶中,对汽车各部分各系统工作状况进行 自动检测,当汽车设备出现不正常时,单片机根据传感器检测到各种警情信号分 别进行报警,提醒车主进行处理,避免事故发生。
