摘要
本文利用C8051F310单片机、RF收发模块和单总线温度传感器设计了一个服务于电力机车的电机状态监测系统。系统利用单片机片内AD器件和单总线温度传感器来完成电机参数的数据采集。数据暂时存放在片内开辟的缓冲区,之后通过SPI接口发送给RF收发模块并发射至接收端,接收端通过一块相同的RF模块接收数据并通过串口将数据传至上位机进行后端处理。
This paper introduces a wireless monitoring system for the engine of the electrical locomotive. It is composed of a singlechip-computer C8051 F310, RF modules and a l-wire temperature sensor. The data from the on-chip A/D convertor and 1- wire temperature sensor is set through SPI to the RF module and then transmitted to the receiver. The receiver receives the data with a same RF module and transfers them to PC for final processing.
