Coal mine safety monitoring system

Abstract

The invention discloses a coal mine safety monitoring system. The system comprises system ground equipment and system underground equipment; the system ground equipment comprises a UPS, a defibrillator, a monitoring host machine, a monitoring standby machine and a ground network switch; and the ground network switch is connected with the system underground equipment through an optical fiber; an underground industrial ring network is provided with at least two underground ring network switches; the first underground ring network switch is connected into the input end of a first monitoring substation, and at the same time, a first power source box is connected into the input end of the first monitoring substation; the first monitoring substation is provided with four output ends; the secondunderground ring network switch is connected into the input end of a second monitoring substation, and at the same time, a second power source box is connected into the input end of the second monitoring substation; and the second monitoring substation is provided with four output ends. The coal mine safety monitoring system of the invention has the advantages of high working efficiency, stable product quality, reliable safety, accurate monitoring, simple structure and convenient maintenance.

Description

technical field [0001] The invention relates to the technical field of mine monitoring equipment, in particular to a coal mine safety monitoring system. Background technique [0002] In recent years, coal mine safety accidents have occurred frequently. The coal mine safety monitoring system is an important guarantee for improving the safety of coal mine mining. The coal mine monitoring system is mainly used to detect methane concentration, carbon monoxide concentration, carbon dioxide concentration, oxygen concentration, hydrogen sulfide concentration, mine dust concentration, wind speed , wind pressure, humidity, temperature, power supply status, etc., and realize methane over-limit acousto-optic alarm power-off and lockout. Therefore, coal mining enterprises must always monitor underground changes to ensure that they can meet the needs of normal production in coal mines. However, the existing The design of the monitoring system in the technology is not perfect, and it has ...

[0002] In recent years, coal mine safety accidents have occurred frequently. The coal mine safety monitoring system is an important guarantee for improving the safety of coal mine mining. The coal mine monitoring system is mainly used to detect methane concentration, carbon monoxide concentration, carbon dioxide concentration, oxygen concentration, hydrogen sulfide concentration, mine dust concentration, wind speed , wind pressure, humidity, temperature, power supply status, etc., and realize methane over-limit acousto-optic alarm power-off and lockout. Therefore, coal mining enterprises must always monitor underground changes to ensure that they can meet the needs of normal production in coal mines. However, the existing The design of the monitoring system in the technology is not perfect, and it has problems such as poor anti-interference ability, backward sensing technology, and poor data processing ability. These problems often lead to inadequate mine safety monitoring. In order to improve this situation, improve monitoring quality and work efficiency , the present invention proposes a coal mine safety monitoring system
