Abstract

The invention discloses a wireless sensor-based mine environment harmful gas detection system. The system is composed of a plurality of detection units and a detection center computer, and realizes the multi-point simultaneous detection and condition discrimination of harmful gases in mine environment, the detection units realize detection of the characteristic parameters of harmful gases at detection points, information interaction of all the detection units and the detection center computer is realized through a wireless communication module, the detection center computer is used for processing and managing data of harmful gases in the detected mine environment, and grade discrimination of conditions of the harmful gases at the detection points, detection surfaces and the whole detection environment is realized through a plurality of groups of wavelet neural network identifiers The detection system is designed to solve the problems of low accuracy and poor real time property of present coal mine harmful detection technologies, and realizes multi-point simultaneous detection of the practical conditions of the concentration of the harmful gases in the coal mine by uniformly distributing gas inlets in different positions of the detected coal mine according to the practical conditions of coal mine detection points.

Description

technical field

[0001] The invention relates to the technical field of intelligent detection and control of mine environment and control network, in particular to a detection system for harmful gas in mine environment based on wireless sensors. Background technique

[0002] At present, to ensure the safety of coal mine production, prevent coal mine accidents, protect the personal safety of coal mine workers, promote the development of the mining industry, and ensure sufficient fresh air for underground personnel, the harmful gases and dust must be diluted below the safe concentration, which include CO, H2S, CO2, CH4 and other gases, so the distribution of harmful gases must be measured.

[0003] The sources of the above-mentioned gases are many. For example, CO is mainly produced in coal mines due to spontaneous combustion of coal, decay of pit wood, and smoke from blasting. Monitoring the change trend of CO concentration in underground coal mines can be used as an indicator...
