Underground coal mine environment information monitoring system based on Internet of Things

Abstract

The invention discloses an underground coal mine environment information monitoring system based on the Internet of Things is composed of an underground coal mine environment information monitoring center and a plurality of underground coal mine environment information monitors. The underground coal mine environment information monitoring center comprises a central control unit, a Zigbee wireless network coordinator and an early warning device. Each underground coal mine environment information monitor comprises a gas concentration measuring instrument, a CO concentration measuring instrument, a dust concentration measuring instrument, a temperature measuring instrument, a humidity measuring instrument, an ARM microcontroller, a Zigbee communication module, a power source and an alarm device. The underground coal mine environment information monitoring system based on the Internet of Things has the advantages of being simple in structure, wide in coverage, intelligent, comprehensive in information collection, good in real-time performance and the like, the gas and other inflammable gases can be accurately monitored in real time, early warning can be carried out on the underground coal mine gas, the fire disaster and other danger sources and hidden dangers, the safety of mine production can be improved, and accidents are prevented.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a coal mine underground environment information monitoring system based on the Internet of Things. Background technique [0002] my country is a country rich in coal resources and also a country that is relatively dependent on coal resources. In my country's energy industry, coal accounts for 76% and 69% of the total primary energy production and consumption respectively. For a long time to come, my country's energy structure will still be dominated by coal. [0003] The mining of coal resources has always been an important basic industry in my country, and safety is the top priority of coal production, which plays a role in guaranteeing, supporting and promoting coal production. In recent years, my country's coal mine safety production has made great achievements, showing a stable and improving trend. But at the same time, we should see that most of my country's coal mines are undergroun...

AI Technical Summary

Problems solved by technology

But at the same time, we should see that most of my country's coal mines are underground mining, with complex geological conditions and harsh production conditions. There are always threats of roof pressure, gas outburst, coal dust, fire and other natural disasters; and the safety production equipment of coal mines is backward, management Non-standard, unable to effectively monitor the coal mine production environment and give early warning to abnormal situations, forming a safety hazard
