摘要
网络和PLC技术的发展,网络通讯与PLC结合,从而实现远程数据传输与控制。水厂供水装置通过DDE远程数据传输,实现了取水泵房自动控制、数据监测、变频器调速和供水装置清水池恒水位控制。提高生产的效率,降低能耗,对确保水厂装置稳定运行起到了重要作用。
With the network and PLC development,the integrating of the network commucating and PLC,the remoting data transmitting and controlling have been realized.The remoting data of the the supply water unit in the water plant are transmitted by DDE,the pump automatic controlling,data detecting,the adjusting speed by frequency conversion and the pure constant water level controlling of the supply water unit are realized.It can improve the production efficiency and lower the energy consuming,and it is critical for the the supply unit can be worked stably.
