Problems solved by technology

In some spontaneous combustion coal mines in China, temperature monitoring probes are placed in goafs, but manual inspection methods are basically used for observation.
In terms of fire monitoring of tape machines, smoke sensors are basically placed on tape machines to monitor fires. The sensors can only monitor the presence or absence of smoke, and cannot realize early prediction of tape machine fires.

Abstract

The invention discloses a coal mine underground fire monitoring system. The system comprises a monitoring host, a communication master station and a wireless sensor network, wherein the wireless sensor network is communicated with the monitoring host through the communication master station, and the wireless sensor network comprises sensor nodes used for collecting safety data of a coal mine and awireless gateway. The system not only can timely and accurately monitor the fire condition underground the coal mine, but also can effectively control the energy consumption of the sensor nodes so asto prolong the service life of the wireless sensor network.

Description

technical field [0001] The invention relates to the technical field of coal mine safety monitoring, in particular to an underground coal mine fire monitoring system. Background technique [0002] At present, the monitoring and forecasting of spontaneous combustion fires in coal mines in my country mainly uses the bundle tube monitoring system, which analyzes the concentration of generated gas in underground roadways and goafs to predict spontaneous combustion through bundle tube sampling. The advantage of bundle tube technology is that there is no electrical equipment underground, but it is limited to the analysis of fire gas, and cannot monitor the spontaneous combustion temperature and air leakage status of the fire area. At the same time, the bundle tube equipment also has technical defects such as long gas transmission distance, delayed sampling time, poor real-time analysis data, accumulation of condensed water in the bundle tube, difficult to deal with blocked pipeline...
