Coal mine underground sump intelligent drainage control system based on big data

Abstract

The invention discloses a coal mine underground sump intelligent drainage control system based on big data, which is used for solving the problems that in the prior art, the working capacity and the working state of a water pump body are not inspected by detecting technical parameters of the water pump body, and different numbers of water pumps are not adopted for draining water at different waterlevel heights. The coal mine underground sump intelligent drainage control system is provided with a liquid level sensor I and a liquid level sensor II, through comparison of acquired quantities, when a difference value of acquired data is large, an alarm instruction is sent to an alarm module to drive an alarm device to give an alarm, and when the value of the acquired data is within an allowable error range, and a water level numerical value acquired by the liquid level sensor I is taken as a standard to be sent to the control module. In this way, collection errors of the liquid level sensor are reduced, and timely maintenance is conducted. The number of started water pumps is judged according to the water level acquired for the second time, and all the water pumps are directly startedwhen the water level exceeds the early warning limit value, so that water can be pumped and drained quickly, electric energy can be saved, and the energy-saving purpose is achieved.

Description

Technical field[0001]The invention relates to a drainage control system, in particular to an intelligent drainage control system for underground coal mine sump based on big data, and belongs to the technical field of intelligent drainage of underground coal sump.Background technique[0002]At present, with the rapid development of control theory and automation technology, PLC control modules are widely used in the field of industrial control, making it possible to realize automatic control of mine drainage. Automated drainage can free up labor, make the drainage pump run intelligently, and realize the optimal drainage function.[0003]Patent CN109343456A discloses a mine drainage control system, including a human-machine interaction module, a control module, a frequency conversion control module, a liquid level sensor and a water pump unit. The liquid level sensor monitors the mine water level information and transmits it to the control module. The control module is controlled by the fr...

Problems solved by technology

[0005] The purpose of the present invention is to provide a coal mine underground water tank intelligent drainage control system based on big data, which is used to solve the problem that the existing technology does not examine the working ability and working state of the water pump body by detecting the technical parameters of the water pump body, and does not check the water pump body. Different water levels use different numbers of water pumps for drainage. The present invention is equipped with liquid level sensor 1 and liquid level sensor 2. By comparing the collected data, when the collected data difference is large, an alarm command is sent to the alarm module to drive the alarm. When the collected data value is within the allowable error range, the water level value collected by the liquid level sensor 1 is sent to the control module as a standard, in this way to reduce the collection error of the liquid level sensor and carry out timely maintenance; The water level of the secondary collection is used to determine the number of pumps to be turned on. When the water level exceeds the warning limit value, all the water pumps are directly turned on. This method can not only pump water and drain water quickly, but also save electricity and achieve the purpose of energy saving;
