Embodiment：
A kind of control system of the power station wastewater treatment based on PLC controller, as shown in Figure 1, including PLC master controllers,
Relay operation room, wastewater treatment place, the relay operation room include embedded controller and intermediate relay, it is described after
The indoor intermediate relay at least two of operation of electrical appliances, is divided into input terminal intermediate relay and output terminal intermediate relay, institute
It states PLC master controllers to connect with embedded controller, the output terminal intermediate relay connects embedded controller, the input
Intermediate relay connection embedded controller is held, the wastewater treatment place is equipped with contactor, acid-base neutralization device, sewage disposal
Equipment, monitoring device, contactor are equipped with contactor normally opened contact, and contactor normally opened contact connection input intermediate relay connects
Tentaculum one end connects output terminal intermediate relay, contactor other end connection acid-base neutralization device, acid-base neutralization device and sewage
Processing equipment connects；The system uses the control model of upper and lower computer, and host computer uses PLC master controllers, and as slave computer
Embedded controller communicated using RS485, host computer is mainly completed to acquire the data information of each system and equipment in real time,
Automatically operation arrangement, the statistical data report after arrangement is handled, and the Real time dynamic display on picture are carried out to data information
Actual value automatically saves data information, and exports corresponding controlled quentity controlled variable, when monitoring system monitoring to the every ginseng in sewage disposal scene
