Underground staff detecting instrument and staff monitoring system based on miner light weak light detection

Abstract

The invention relates to an underground staff detecting instrument and a staff monitoring system based on miner light weak light detection. The detecting instrument is provided with a light detector with high sensitivity, a light detector with low sensitivity, and an electronic control module which is electrically connected with the two light detectors; a comparing unit and a storing unit are arranged in the electronic control module; a preset illumination lower limit value is stored in the storing unit; the comparing unit is used for comparing a practical illumination value detected by the light detector with low sensitivity with the illumination lower limit value; when the practical illumination value detected by the light detector with low sensitivity reaches or exceeds the illumination lower limit value, the electronic control module controls the light detector with high sensitivity to stop working; and the system comprises a plurality of detecting instruments, a plurality of transmission substations and a management master station which are connected and communicated pairwise. According to the underground staff detecting instrument and the staff monitoring system based on miner light weak light detection, detection and alarm for miner light weak light can be realized, and whether people are in a blasting area or not can be judged under the condition without adding personal operation equipment of miners, so that burdens of the miners can be reduced, and the difficulty in managing the equipment is reduced.

Description

technical field [0001] The invention relates to an underground personnel detector for detecting the presence or absence of a miner's lamp signal in a coal mine based on the weak light detection of a miner's lamp and an alarm system for underground personnel detection and safety alarm using the detector. Background technique [0002] At present, my country has become the largest country in coal production and consumption in the world. At the same time, my country is also a country with many coal mine safety accidents. Coal mine safety accidents have caused serious property losses and bad social impacts. Especially in recent years, coal mine accidents caused by blasting have an obvious relative upward trend. In order to prevent the occurrence of blasting accidents, it is necessary to detect that there is no person in the blasting warning area when blasting, so as to realize the purpose of "the blasting area cannot be fired if there are people in the blasting area" through a ce...

Problems solved by technology

The disadvantage is that individuals may or may not carry equipment such as radio frequency cards, and the equipment carried by individuals is easily damaged, and it is not easy to be found after damage. into an accident

The second is that infrared imagers can be used to detect people, but the disadvantage is that the price is too expensive
