摘要
针对现有火车站上水系统自动化程度低、管理不便等不足,设计了一套火车站智能上水栓系统。上水栓的股道管理机(上位机)由西门子S7-300与S7-200构成,以STC11F08XE单片机作为主控芯片,上水栓与股道管理机之间通过RS-485总线通信。具有反应速度快、控制方便、运行可靠、便于维护管理、成本低等优点。经测试验证能很好的完成各项控制指令,满足了现代火车站智能上水的要求。
： In view of low degree automation and inconvenient management of existing railway station water hydrant system, this paper designs an intelligent water hydrant system at railway stations. The track supervisor of the hydrant { upper computer） is composed of Siemens $7 -300 and $7 -200. STC11F08XE microcontroller is used as master chip and the water supply hydrant communicates with the track supervisor through RS -485 bus. The system has such advantages as quick response, convenient control, reliable operation, easy maintenance and low cost. It has been verified through the test that this system can implement all control commands very well and meet the requirements of modem intelligent water supply at railway stations.
