Coal mine underground integrated monitoring and controlling system based on internet of things technology

Abstract

The invention discloses a coal mine underground integrated monitoring and controlling system which mainly comprises a sensing and detection device, a security information network and communication device, a security information management device, a security early warning and decision support device and a rescue information assurance device. The system can perfectly solve the problems of existing coal monitoring and controlling systems, prevent the occurrence of coal mine underground signal loss effectively and improve the level of coal mine security monitoring greatly.

Description

technical field [0001] The invention relates to the technical field of underground coal mine safety monitoring, in particular to an integrated underground coal mine monitoring system based on Internet of Things technology. Background technique [0002] my country is a large coal-producing country, but in terms of natural conditions, the coal seams in my country are generally unsatisfactory. The vast majority of mines are in poor conditions and are threatened by natural disasters such as gas, roof, and water seepage to varying degrees. The objective conditions for frequent occurrence of safety accidents. With the country's continuous improvement of safety production requirements for coal mine enterprises, coal mine safety monitoring and monitoring systems are widely used in large and small domestic coal mines. The equipment of safety monitoring system can greatly improve mine safety production level and safety production management efficiency, and is an effective way to preve...

Problems solved by technology

[0004] 1. Downhole data collection is difficult to meet the requirements of safety production monitoring

Underground sensors are usually only deployed near the mining face, while other places with high potential safety hazards are insufficiently deployed, resulting in blind spots in the safety production monitoring system; existing coal mine underground safety monitoring systems mostly use wired methods, and a wired transmission system needs to be laid. To a large extent, the expansion of the network scale is limited, making the coverage of underground monitoring insufficient

[0005] 2. Low degree of system sharing

The existing coal mine safety production monitoring systems come from different manufacturers, the communication protocols are incompatible with each other, and there is a lack of standard transmission equipment interface standards, which makes the transmission equipment of different manufacturers incompatible and unable to share the transmission network

At the same time, due to the lack of a unified monitoring data information standard, the independent operation of each system is incompatible with each other, and the information of different monitoring systems cannot be shared, forming "information islands" one by one, which is not conducive to comprehensive management and decision-making of coal mining enterprises

[0006] 3. The degree of information utilization is not high

The existing coal mine safety monitoring system can only realize the collection of safety data and simple alarm function, and cannot model and analyze based on the existing historical safety data and re
