摘要
一个水泵房为多个山头的水塔供水,因为传输距离较远,水位信号无法及时得到反馈,给供水工作带来很大的麻烦;文中引入数传电台完成与水塔水位信号反馈,利用PLC对接收到的各个水位信号进行变频调速,从而实现恒压供水。
One pump supplies water for multiple towers on different hills in the distance and there is more trouble as the water level feedback signal can not get to controller. The system used digital broadcasting station to complete signal feedback of the tower＇s water level, and used PLC to deal with receiving various water level signal and to implement frequency control, and realized constant pressure water supply.
