摘要
针对直接式汽车轮胎压力监测系统(Tire Pressure Monitoring System,TPMS)存在的关键技术问题,设计了基于SP12传感器、无线发射芯片TDK5100F的直接式汽车轮胎压力监测系统。系统由4个轮胎检测模块、1个中央接收模块以及1个显示模块组成。轮胎检测模块采用气门嘴外置式安装方式,通过轮胎检测模块连接到显示模块上进行设置来实现轮胎检测模块的定位。系统安装方便,便于更换电池,且成本较低,可以作为独立的装置安装在汽车上,还可通过车载网络接口和其它模块通信。
After introducing some key technologies of TPMS, a TPMS based on sensor SP12 and transmitter TDK5100F was designed to solve the problems in current TPMS. A reliable, convenient and low cost location method was adopted to locate the tire-monitoring module easily. The installation of TPMS with tire valve outside is con- venient to replace batteries. The TPMS can be installed in vehicles as an independent module, and can use its vehicle network interface to communicate with other modules.
