Mine surrounding rock monitoring system based on wireless sensor network

Abstract

The invention discloses a mine surrounding rock monitoring system based on a wireless sensor network. The system comprises a data monitoring module, a data transmission module and a ground monitoring center. The data monitoring module is used for collecting characteristic changes resulting from surrounding rock stress change in an underground coal mining process, wherein the collection comprises temperature collection, pressure collection and slight vibration signal collection. The data transmission module is used for transmitting collected temperature, pressure and slight vibration signals to the ground monitoring center through adoption of a wireless sensor network technology. The ground monitoring center is used for analyzing geological condition according to the change of received monitoring data when underground mining is carried out and carrying out alarm when an abnormity occurs in the monitoring data. The system has the beneficial effects that through adoption of the wireless sensor technology, the security monitoring of mine surrounding rocks is realized; in the wireless sensor network, a cluster head in the network is selected through adoption of an improved LEACH algorithm; a cluster head competition condition is optimized; and the problem that cluster head nodes are not distributed uniformly is overcome.

Description

technical field [0001] The invention relates to the technical field of coal mine safety monitoring, in particular to a mine surrounding rock monitoring system based on a wireless sensor network. Background technique [0002] The research and development of mine surrounding rock wireless monitoring system provides technical means and basis for early prevention of surrounding rock disasters in the mine mining process.
