Automatic drainage monitoring system under coal mine wells

Abstract

The invention discloses an automatic drainage monitoring system under coal mine wells. The automatic drainage monitoring system comprises a main controller, a digital quantity signal detecting unit, an analog quantity signal detecting unit and a power supply module, wherein the main controller is connected with a remote extension module, a touch control platform and a comprehensive protection unit for high-voltage boards, the digital quantity signal detecting unit and the analog quantity signal detecting unit are connected to the input terminal of the main controller through the remote extension module, and a digital quantity input module and an analog quantity input module are respectively connected to positions among the remote extension module, the digital quantity signal detecting unit and the analog quantity signal detecting unit; the output terminal of the main controller is connected with a water-pump motor control module, an electromagnetic-valve control module, an electric-valve control module and a sound-light alarm control module through a digital quantity output module. According to the automatic drainage monitoring system disclosed by the invention, the running state of equipment is controlled through the real-time data detection of the system, the remote management of the operation of the equipment is realized by adopting the remote extension module, and the automatic drainage monitoring system has the characteristics that the automaticity is high, on-site programming and maintenance are easy, and the like.

Description

technical field [0001] The invention belongs to the technical field of water supply and drainage, and in particular relates to an automatic drainage monitoring system for underground coal mines. Background technique [0002] The coal mine underground drainage system is one of the four major components of coal mine production. The performance of the drainage system is directly related to the safety of coal mine production. , There is often a large amount of accumulated water underground, and they must be removed to ensure the safety of underground operations and the personal safety of workers. At present, the underground drainage systems of some coal mines in my country are controlled by relays. The start, stop and selection of water pumps are all done manually. In addition, the underground environment is harsh, which inevitably leads to misoperation. A large amount of real-time data of the underground drainage systems cannot be uploaded to the ground control center. If it is...

At present, the underground drainage systems of some coal mines in my country are controlled by relays. The start, stop and selection of the water pumps are all done manually. In addition, the underground environment is harsh, which inevitably leads to misoperation. A large amount of real-time data of the underground drainage systems cannot be uploaded to the ground control center. It is monitored in real time, and the failure of the system cannot be dealt with in time, which brings great hidden dangers to the safe production of coal mines.
