机动车辆轮胎气压监测远程报警系统

Wireless Alarm System for Tire Pressure Monitoring of Motor Vehicle

本文设计了一种安全有效的车辆轮胎气压检测无线报警系统,采用了直接测量法通过气压传感器将气压信号转换为电信号,再经过精密的放大和处理转换为两位输出的TTL电平数字信号,驱动报警电路和短信通信报警系统,实现现场自动报警、GSM短信自动通信报警等功能。该系统可以有效测定每个轮胎内部的实际压力情况,能及时可靠报警,增强了驾驶员的安全意识,最大限度地避免了事故的发生。

The paper designs a safe and effective wilureless alaml system for the puressure. It adopts a diurect measurement method to acquiure and convert the signal in pneumatic sensor, and then peffoures a precise amplification and processing to convert into two bit output. The alarm circuit and SMS conmmnication alaure system is driven matic on-site alarm and GSM SMS conmmnication alamL The system can effectively inside each tiure to timely make alarm and enhance the driverg safety awureness so as rence of accidents. measulurement to an electric signal through a the digital signal of TTL level to realize the function of autodeteureine the actual situation to effectively avoid the occurrence of accidents.
