摘要：为实现整个排涝系统的测控目的，架构了Controller Link和DeviceNet两级总线控制网络。主站PLC与中控室工控机通过RS232C进行上位机连接，主站与各子站之间采用Controller Link网络连接，子站通过DeviceNet总线采集各种传感器信息，并实现了现场信号的输入输出。研究结果表明，从控制层到设备层的网络通信提高了排涝站的运行可靠性和工作效能，这对于研究和建设现代化无人监控排涝站具有一定的理论意义和实用价值。

Abstract: Aiming at realizing the scheme of measuring and controlling of the whole pump system, two levels of bus control networks Controller Link and DeviceNet were constructed. Main PLC was communicated with industrial controller in central control room by RS232C. The main station was connected with substation in Controller Link network connection.And the substation collected various information of sensors to obtain input and output of the field signals in DeviceNet network connection. The research results indicate that the network communication from control layer to device layer improves the reliability and efficiency of the stations operation,and its theoretical and practical to study and set up modern unmanned supervisory control drainage station.
Key words: drainage stations; field bus; programmable logic controller(PLC) network; monitor system
