Mine ventilation monitoring system

Abstract

The invention discloses a mine ventilation monitoring system comprising an overground monitoring system and an underground sampling system. The overground monitoring system comprises two industrial control computers and a sound and light alarm system; and one industrial control computer is used for system monitoring, and the other industrial control computer is used for data backup. The underground sampling system comprises a PLC (programmable logic controller), a wind speed sampling module, an air pressure sampling module and a fan operation monitoring module, and can be expanded according to system requirements to monitor indicators of underground CO concentration, NO2 and the like. Communication between the overground monitoring system and the underground sampling system is performed by using RS485. Compared with the prior art, the mine ventilation monitoring system has functions of monitoring changes of air speed and air pressure force of the mine in real time, alarming on exceeding standard and the like; compared with a conventional ventilation monitoring system, the PLC device system has the advantages of low fault rate, high reliability, simple wiring, strong anti-interference capacity, convenience in maintenance and the like; and meanwhile, by the aid of the PLC technology, automation of the ventilation system is greatly improved, and labor force of staffs in working positions is reduced.

Description

technical field [0001] The invention relates to an underground mine ventilation technology, in particular to a mine ventilation monitoring system, which can be widely used in mine ventilation systems for underground mining. Background technique [0002] The mine ventilation system is an important part of mine safety production. Whether the mine ventilation system can work normally is closely related to the working environment conditions, production efficiency and safety production in the mine. The conventional mine ventilation monitoring system has the following problems. The environment is special and complex, and the monitoring equipment is easily eroded and damaged by the environment. In addition, some monitoring equipment has low precision, and it is difficult to accurately and timely send various environmental parameters in the mine for the staff to check. These technical problems will eventually give The underground staff brings great safety hazards, which makes there ...
