基于MPXY8300传感器的胎压监测系统的设计与实现

摘要

针对目前轮胎压力监测系统存在的节能效果差和定位复杂的问题,设计并实现了基于MPXY8300传感器的胎压监测系统,该系统由中央模块、轮胎模块和低频唤醒模块组成.中央模块利用微控制器MC9S08RG60和射频收发器MC33696来实现显示和报警功能；轮胎模块利用MPXY8300实现轮胎压力、温度和加速度的检测与发射；低频唤醒模块利用MC33690实现轮胎模块的唤醒和定位.最后通过对系统的测试,验证了系统的可行性.%In order to solve the existing TPMS problem on the low energy-saving effect and complex positioning,a TPMS based on MPXY8300 sensor was designed and realized. The system consisted of a central module,four tire modules and four LF wake-up modules. The oentral module can realize the display and alarm function with the MC9S08RG60 micro-controller and the MC33696 RF transceiver. The tire module can measure and send the tires' pressure, temperature and acceleration signals with the MPXY83OO sensor. The LF wake-up module realized the auto awake and positioning function with MC33690. The feasibility of the system is verified with an integration test.
