Intelligent drainage control system and control method thereof

Abstract

The invention relates to an intelligent drainage control system and a control method thereof, which relates to a drainage system and is especially suitable for substation flood control and drainage, mine drainage and warehouse and grain depot flood control and drainage. The intelligent drainage control system comprises an intelligent central controller, a pump current signal input and comparison module, a liquid level signal input and comparison module, a liquid level sensor, a pump current sensor, a liquid level signal sending unit module, a current signal sending unit module, a manual control input module, a time setting module, a control output module, a pump control unit, an alarm module, a display unit module, a communication module, a wireless remote control module, a remote mobile phone control terminal, a remote control center platform and a power module. The novel manual and automatic remote and local intelligent drainage with real-time data monitoring is realized; the functions of a change-over switch and a start-stop button can be integrated with a novel drainage controller; equipment failure caused by bad contact is reduced; and control parameters can be set or changedflexibly.

Description

technical field [0001] The invention relates to an intelligent drainage control system and a control method thereof, which are especially suitable for substation flood control drainage, mine operation drainage, warehouses, and grain depots flood control drainage. Background technique [0002] At present, the drainage control of most substations simply uses the float switch to control the start and stop of the water pump. The float is installed at the position to be controlled. When the liquid level rises to a certain position, the pump starts and the float outputs the switch . It is easy to not return to the position during the use of the float, thus miscontrolling the water pump. And the operator cannot know the current water level accurately in real time. The protection of the water pump is to protect the water pump from no-load or overload through a thermal relay. When the manual and automatic switching control of the drainage control equipment is carried out on site, ...

AI Technical Summary

Problems solved by technology

[0004] 1. It is impossible to monitor the height of the water level and the working current of the pump in real time and intuitively, and it is impossible to effectively protect the equipment;

[0005] 2. The control of the remote monitoring platform and the monitoring and operation of wireless mobile phones cannot be realized;

[0006] 3. The contact of the float switch is not easy to return to the position in the water, which makes the water pump malfunction;

[0007] 4. It is impossible to set the data of liquid level control points according to different working environments (such as no-load current, overload current, control liquid level, pump working time, etc.);

[0008] 5. Mechanical transfer switches and buttons are easily oxidized outdoors for a long time, resulting in poor contact, increasing failure points and increasing the workload of staff;

[0009] 6. There is no alarm WeChat push. When the equipment fails, it can only be found and solved by the staff during the inspection.
