Coal mine down-hole fire monitoring system based on wireless sensor network

Abstract

The invention provides a coal mine down-hole fire monitoring system based on a wireless sensor network. The system comprises a monitoring host, a communication master station and the wireless sensor network, wherein the wireless sensor network communicates with the monitoring host through the communication master station, is a ZigBee wireless self-organized network and comprises a wireless sensorand a wireless gateway; and the wireless sensor is used for acquiring coal mine safety data and wirelessly transmitting the coal mine safety data and comprises a wireless carbon monoxide sensor, a wireless wind pressure sensor and a wireless temperature sensor. Therefore, according to the coal mine down-hole fire monitoring system based on the wireless sensor network provided by the embodiment ofthe invention, coal mine down-hole fire conditions can be timely and accurately monitored, the energy consumption of a wireless sensor network node can be effectively controlled, and the service lifeof the wireless sensor network can be prolonged.

Description

technical field [0001] The invention relates to the field of coal mine safety monitoring and wireless communication, in particular to a coal mine underground fire monitoring system based on a wireless sensor network. Background technique [0002] The geological conditions of coal mines in my country are complex, and fire is one of the main spontaneous combustion disasters in coal mines. In my country, coal mines with the risk of spontaneous combustion account for a large proportion and cover a wide area. Among the large and medium-sized coal mines, 72.9% of the coal mines have serious or relatively serious spontaneous combustion hazards. Due to spontaneous combustion of coal seams, my country loses about 200 million tons of coal resources every year. Spontaneous combustion is also one of the causes of major vicious accidents caused by coal mine gas explosions, causing tragic accidents. [0003] With the improvement of my country's coal mine mechanization, the proportion o...

AI Technical Summary

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.

[0007] In terms of belt machine fire monitoring, smoke sensors are basically placed in the belt machine alley to monitor fires. The sensors can only monitor the presence or absence of smoke, and cannot realize early prediction of belt machine fires.
