青藏铁路站区给排水系统自动控制工程试验

Experiment on Automatic Control Engineering of Water Supply and Drainage System in Station Area of Qinghai-Tibet Railway

针对青藏高原特殊的自然环境特点与铁路管理无人值守的要求,采用了由PLC模块、采集模块及数字化探头组成的智能测控系统,该系统具有全数字、易联网、易扩展、高可靠等特点。自控系统所采用的三层网络结构及控制逻辑应用于高原铁路的实际工程,表明了其安全可靠性和切实可行性。

According to the special natural environment characteristics of the Qinghai-Tibet Plateau and the requirements of unattended railway management, the intelligent measurement and control system composed of PLC modules, collection modules and digital probes was used in the experiment. This system has the characteristics of all-digital, easy networking, easy expansion, high reliability and so on. The application of three-tier network structure and control logic to the practical engineering of Qinghai-Tibet Railway shows that the system is reliable and feasible.
