Exploiting-following wireless intelligent spraying dustfall control system for mines

Abstract

The invention relates to an exploiting-following wireless intelligent spraying dustfall control system for mines, which is applied to combined mining (caving) working surfaces. The control system consists of an end head monitoring controller, a node spraying dustfall controller and a coal winning machine infrared emission sensor, wherein the node spraying dustfall controller comprises node sensor systems and controller systems; each node sensor system comprise a hydraulic pressure switch sensor, a coal dust concentration sensor, a pedestrian photosensor and an infrared receiving sensor; the infrared emission sensor emits sector infrared lasers, and scans the infrared receive sensor to obtain the working position of the coal winning machine so as to control and open a region spray head under wind flows and perform spraying dustfall. The hydraulic pressure switch sensor obtains the position allowing coal to be put, and controls and opens the spray head to discharge the coal and remove dust. Controllers are in wireless communications, so that the wiring error can be avoided, and maintenance and repair are simple. According to the invention, the design of internal circuits conforms to the standards and the requirements for the production technology of mine safety, and the control system has the functions of explosion prevention, dust prevention and water prevention.

Description

technical field [0001] The invention relates to a spray dust reduction control system, which belongs to the technical field of coal mine environmental protection and safety facilities, in particular to a mine-used intelligent spray dust reduction control system. Background technique [0002] As an inevitable product in the process of coal production and processing, mine dust is one of the five natural disasters in coal mines. It not only causes occupational diseases and endangers the health of workers, but also many dusts are explosive, which seriously threatens the safe production of mines. [0003] In the coal production process, almost all operations may generate dust. In particular, the high-yield and high-efficiency coal mining technology with a high degree of mechanization makes the dust concentration in the air of the underground operation point reach a very high level. Judging from the current situation of dust production in my country's coal mining face, according...

Problems solved by technology

However, all the controllers mentioned in this patent are connected by wires. There are many lines and the wiring is complicated. However, the space on the working surface is narrow and long, the cables are not easy to arrange, and it is easy to cause wiring errors and complicated maintenance.

In addition, the underground environment is complex, and the use of light control sensors is susceptible to interference from various miner's lamps
