基于双单片机车站数据收发器的研制

Design of Station Data Transceiver Based on Two Single Chip

介绍一种火车车站数据收发器的硬件和软件设计,该收发器不但需要接收本站采集器的数据,而且还要把数据向上发送给离调度中心较近车站的收发器,收发器采用RS485总线技术与本站的采集器进行数据传输,而与车站间收发器的数据传输采用Modem技术,实现了在普通电话线上进行20km的远距离数据传输。

This paper introduces design of hardware and software about railway station data transceiver,and it receives dada in lo- cal collection device and transmits dada to next transceiver.Transceiver adopts RS485 bus technology in local station and data transmission adopts Modem technology between stations,which achieve 20km remote data transmission in common line.
