STC89C52单片机汽车防盗报警系统设计+GSM电话报警

更新时间:2011-12-15:  来源:毕业论文

Car has become more and more people are the indispensable part in life, car theft has become the most common in modern society, the crime on market now one of a variety of automobile guard against theft, alarm system exist to varying degrees misstatement rate is high, anti-theft simple function, and reaction speed slow shortcomings. This topic in designing a new kind of car anti-theft alarm system, this alarm system to STC89C52 single-chip microcomputer control module, adopts mainly in SW - 18015P earthquake sensor, the external vibration signals collected mobile phone GSM call alarm, the acousto-optic alarm, with high performance 70m NRF2401 wireless remote control module implements the remote shut-down alarm system ,implements a reliable, efficient, low-cost car anti-theft alarm system.
Key words: MCU GSM Wireless communication Alarm’ device
