摘要：為實(shí)現(xiàn)整個(gè)排澇系統(tǒng)的測(cè)控目的，架構(gòu)了Controller Link和DeviceNet兩級(jí)總線控制網(wǎng)絡(luò)。主站PLC與中控室工控機(jī)通過(guò)RS232C進(jìn)行上位機(jī)連接，主站與各子站之間采用Controller Link網(wǎng)絡(luò)連接，子站通過(guò)DeviceNet總線采集各種傳感器信息，并實(shí)現(xiàn)了現(xiàn)場(chǎng)信號(hào)的輸入輸出。研究結(jié)果表明，從控制層到設(shè)備層的網(wǎng)絡(luò)通信提高了排澇站的運(yùn)行可靠性和工作效能，這對(duì)于研究和建設(shè)現(xiàn)代化無(wú)人監(jiān)控排澇站具有一定的理論意義和實(shí)用價(jià)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
