摘　　要：绝大部分的的轮胎故障由轮胎欠压、过压、漏气及胎温过高造成。蓝牙4.0规范的核心是蓝牙低功耗技术(BLE)。设计了一种基于蓝牙4.0的智能汽车轮胎监测系统,系统由传感器MPXY8020A、蓝牙模块主控芯片CC2540和智能手机终端组成,传感器完成轮胎内部压力和温度的采集,蓝牙模块内置80C51单片机,获取传感器数据,将数据处理后发送给手机用户终端。该系统具有能耗低,结构简单、无线传输的优点。This paper designs a tire pressure monitoring system(TPMS)by using Bluetooth 4.0 wireless technology.The system mainly contains three function units:sensor monitoring unit based on MPXY8020A,main control unit CC2540 and a smart phone for display.The sensor unit acquires tire data like pressure,temperature as well as battery voltage.Information of each tire are sent to the main control unit and transmitted to a smart phone.The tire data can be displayed on smart phone in real time,parameters like alarm thresholds can also be set.
