Abstract

The invention discloses a wireless monitoring system for underground coal separation chamber surrounding rock based on mine breeze energy harvesting. The wireless monitoring system comprises a control center, a communication base station, an SINK node and a monitoring terminal which are connected in sequence. The monitoring terminal comprises a displacement sensor, an energy supply unit, a first processor unit and a first communication unit, and the energy supply unit comprises a wind power generation module and an energy management module. Displacement of the underground coal separation equipment chamber surrounding rock can be monitored dynamically, breeze energy existing in the chamber surrounding rock is converted into electric energy through the wind power generation module, the power supply problem of WSN nodes is solved, wireless monitoring of an underground coal separation equipment chamber is realized truly, no circuit needs to be arranged in the chamber, damage to stability of the chamber and a passage by circuit slots is avoided, the chamber environment is not affected, and normal work in the chamber can be conducted conveniently.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of the surrounding rock of an underground coal preparation chamber, in particular to a wireless monitoring system for the surrounding rock of an underground coal preparation chamber based on collection of mine breeze energy. Background technique [0002] Coal is the most important primary energy source in my country. Along with coal mining, the gangue discharged from coal mines is washed through the coal preparation plant on the well. However, the washing on the well increases the transportation cost of gangue and the cost of gangue discharge, resulting in tension in the mine's lifting capacity and a decline in the profit per ton of coal. At the same time, waste rock discharge occupies land, causing ground environment pollution, which is not conducive to the improvement of living environment. Underground coal preparation can directly solve the above problems, realize the integration of u...
