Problems solved by technology

However, in the actual production process, in order to reduce the impact of gas overrun, power outage and lockout on coal production, some underground workers did not install or move the sensor in the specified position, causing major accident hazards such as gas explosion
The current coal mine safety monitoring system can only monitor the working status and communication status of the sensor, but cannot monitor the actual position of the sensor

Abstract

The invention provides a coal mine downhole sensor positioning alarm device. The positioning alarm device mainly comprises a coal mine downhole sensors, a positioning device, a storage device, a data processing device, an alarm device, and a communication device. The positioning device is responsible for positioning of the coal mine downhole sensors, the data processing device is responsible for monitoring the position of the sensors, and when it is monitored that the position movement of the sensors satisfies a preset condition, an alarm signal is sent through the alarm device. The position alarm system can effectively prevent man-made sensor position cheating, ensure reliable and effective work of each sensor, prevent accidents, such as fire and explosion, caused by excessive gas in the coal production process, and effectively ensure safe production of a coal mine.

Description

technical field [0001] The invention relates to a coal mine underground sensor positioning alarm device, and the system relates to the fields of radio communication, underground safety monitoring, positioning technology and the like. Background technique [0002] Coal mine safety monitoring is a necessary measure to curb serious accidents in coal mines. "AQ1029-2016 Coal Mine Safety Monitoring System and Use of Monitoring Instruments" and other safety production industry and coal industry standards have specified the detailed installation locations of methane sensors, wind speed, wind direction and other sensors in various coal mine underground working faces and roadways, and also clearly stipulated The limit value of each sensor and the corresponding automatic processing flow such as power-off lockout can prevent the occurrence of fires, explosions and other accidents caused by gas exceeding the limit in the coal production process, and effectively ensure the safe productio...
