Coal mine safety integrated monitoring system based on Internet of Things

Abstract

A coal mine safety integrated monitoring system based on the Internet of Things comprises an environment information system, an equipment information system, a mobile target tracking and positioning system, a voice communication system, a video monitoring system, a traffic dispatching system, a safety supervision information system, a working plane information management system, a yield monitoring system, a dynamic meter management system, a safety prewarning and decision supporting system and a rescue information assurance system. Nodes of the Internet of Things are installed to a coal mine tunnel, relevant equipment and workers, the nodes of the Internet of Things are connected with relevant sensors and actuating equipment, and objects, needing to be monitored, of an underground coal mine are connected with the Internet according to a unified agreement, so that the coal mine safety integrated monitoring system based on the Internet of Things is formed. The data information of the underground environment and equipment can be collected by every worker and underground equipment through the sensors carried with the workers and the underground equipment; besides, the state information of the workers and the underground equipment can be collected, so that intelligent recognition, positioning, tracking, monitoring and management are achieved.

Description

technical field [0001] The invention relates to the field of coal mine safety monitoring, in particular to a coal mine safety comprehensive monitoring system based on the Internet of Things. 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 prevent coal mine safety accidents. ...

AI Technical Summary

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 real-time collected data, and cannot predict and warn coal mine safety accidents, and cannot timely report The countermeasures and schemes provided by users to prevent accidents have affected the application effect of the safety production monitoring system, and do not yet have the functions of early warning of safety accidents, decision support for emergency rescue of emergencies, and information assurance functions

[0007] 4. Lack of emergency rescue information guarantee function

The existing coal mine safety production monitoring system cannot provide sufficient rescue information, which makes the rescue dispatch on the ground lack of pertinence, which is not conducive to the effective development of rescue operations

[0008] 5. Unable to proactively monitor untrustworthy behaviors underground

The existing coal mine safety monitoring system can only monitor the environment and equipment in the mine, with more monitoring and less monitoring, it is unable to actively monitor these untrustworthy behaviors that endanger mine safety, and cannot detect hidden dangers in time to prevent the occurrence of untrustworthy behaviors

[0009] The defects and deficiencies in the existing coal mine underground safety monitoring system have become the bottleneck problem restricting the safety production level of coal mines
