基于蓝牙的矿山车辆胎压监控系统①

矿山车辆胎压监测是以无损检测技术为基础,通过研究车辆胎压的实时信号,了解矿山车辆的轮胎气压的变化特性,从而达到矿山车辆安全监控提供依据。描述了以LPC2132为核心构成的胎压的监控装置的研究。通过带有蓝牙的传感器模块采集车辆胎压信号,经过调理电路后进行比较计算,若超过规定值就报警,并将数据发送到车载CAN总线上。在此基础上设计了一套基于蓝牙的胎压监控装置,硬件系统主要由传感器、LPC2132处理器,信号调理电路,蓝牙模块和报警模块等组成。软件系统由固件程序,数据收发模块等构成。

Monitoring System of Tire Pressure in Mining Vehicle Based on Bluetooth

Mine Vehicle Tire Pressure Monitoring is based on the non-destructive testing technology. It researches on the real-time vehicle tire pressure signal to understand the pressure changes of the mine vehicle tire, so as to gurantee the security for mine vehicles. This paper surveys the research of the tire pressure monitoring detection device, with LPC2132 as the core. Vehicles tire pressure sensor signal with the Bluetooth module is launched and compared. When it exceeds the security value, the alarm is started, and the vehicle CAN bus can read the data. On this basis, the paper designs a Bluetooth-based tire pressure monitoring device, whose hardware system is composed of the sensors, signal conditioning circuitry, Bluetooth module and alarm module. The software system is made up of the firmware, the display module and the data transceiver module, etc.
