基于无线射频技术的汽车轮胎胎压监测系统研究

胎压异常严重威胁着交通安全,随时会造成交通事故,是汽车安全问题上的一个关键点.针对这个现象,本设计提出了一种基于51单片机的汽车胎压监测系统,以此来实现监测胎压异常的功能.本次设计是以STC89C52单片机为核心,气压传感器、无线传输模块、LCD为主要器件,设计一块接收模块和一块采集模块.将带有压力传感器的采集模块置入...

Research on Automobile Tire Pressure Monitoring System based on RADIO Frequency Technology

Abnormal tire pressure is a serious threat to traffic safety,which can cause traffic accidents at any time,and is a key point of automobile safety issues.In view of this phenomenon,this design puts forward a kind of automobile tire pressure monitoring system based on 51 microcontrollers,in order to realize the function of monitoring tire pressure abnormality.This design is based on STC89C52 single chip microcomputer as the core,pressure sensor,wireless transmission module,LCD as the main device,design a receiving module and a collection module.The acquisition module in automobile tire pressure sensor,through the wireless transmission technology,can transmit tire pressure to accept module in the vehicle,and display on the LCD,to offer the driver tire pressure situation.If the tire pressure exceeds the alarm threshold,sound and light alarm,can be realized with automobile tire pressure real-time monitoring and alarm prompt.
