摘要
介绍一种远距离火车车站数据采集器,该系统的车站现场数据采集采用RS485总线技术,而车站间数据传输采用Modem技术,现场数据采集采用可调域值比较法,且采集系统软件具有自动判错功能,能提高系统的抗干扰能力.
The paper introduces a kind of railway station remote data acquisition device, data acquisition adopts RS485 bus technology in local station and data transmission adopts modem technology between stations, comparing voltage can be changed is used in data acquisition and false code can be identified in system software,improving stability of the system.
