摘要
针对列车上水系统的被控对象多、遥控距离远、控制实时性要求高等特点,设计了一套由MSP430F149单片机、SI4432无线通信模块组成的遥控系统。该系统采用EZMAC PRO协议进行无线通信。无线接收部分通过RS485总线与股道管理机(上位机)通信。经测试,该系统实现了对股道各从站的监测与控制,具有可靠性高、低延时、成本低的特点。
In view of the characteristics of various controlled objects, remote control distance and high real-time requirement of the train water supply system, this paper designs a train intelligent water supply system, which is composed of MSP430F149 MCU and SI4432 wireless communication module. This system adopts the EZMAC PRO protocol to achieve wireless communication. Wireless receiving part communicates with track management machine （PC） through the RS485 bus. It is verified by test that the system can monitor and control the stock road, and also the system has the characteristics of high reliability, low latency and low cost.
