Abstract

The invention provides a wireless fire early-warning system and method for coalmine goaf. The wireless fire early-warning system comprises signal acquisition systems, a signal analysis system and a man-machine interaction system. Each signal acquisition system comprises a mine substation, a wireless relay, a wireless carbon monoxide sensor and a wireless temperature sensor, wherein the wireless relay is wirelessly connected with the wireless carbon monoxide sensor and the wireless temperature sensor separately, and the mine substation is electrically connected with the wireless relay. The signal analysis system comprises a ground host used for converting, analyzing and storing signals acquired by the signal acquisition systems. The man-machine interaction system is used for displaying data obtained after analysis of the signal analysis system. The wireless fire early-warning system is simple in structure, high in timeliness and good in stability and reliability.

Description

technical field

[0001] The invention relates to the field of wireless monitoring, in particular to the field of wireless fire early warning systems for goafs in coal mines. Background technique

[0002] With the vigorous development of high-yield and high-efficiency working faces based on fully mechanized top coal mining in China, the mining and ventilation intensity of the working face has increased, which has increased the volume of goafs and floating coals, increasing the spontaneous combustion of floating coals in goafs. However, fires in gobs often cause expensive fully-mechanized mining equipment to be burned, resulting in huge economic losses. Coal spontaneous combustion in goaf is one of the main disasters that endanger the safe production of coal mines for a long time. For the hidden dangers of coal mines, real-time monitoring of air, temperature and other environments in goafs of coal mines can predict the occurrence of this disaster in advance.
