Description

Technical Field

[0001] The invention relates to the technical field of underground monitoring systems, and in particular to a visual real-time monitoring and early warning device for underground coal mine environments. Background Art

[0002] As people's awareness of safe coal mining increases, early warning of dangerous geology during the mining process has attracted more and more attention. Among them, the coal mining environment is complex and dangerous. The research and development goal of comprehensive mechanized coal mining is to reduce the number of people and make it unmanned. Therefore, informatization, digitization and intelligence will be the main direction of the development of comprehensive coal mining. As an important equipment for comprehensive mechanized mining, the coal mining machine undertakes the key tasks of cutting and loading coal. Its start-up rate and reliability directly affect the mining efficiency and economic benefits of coal mines, which requires the coal mining machine to have high reliability. The reliability of the coal mining machine depends not only on its product quality, but also on whether it is properly operated and maintained during operation. The operator must monitor its operating data in real time and adjust the operating parameters of the equipment at any time to keep it in the optimal working condition, improve operating efficiency and extend its service life. The traditional coal mining machine monitoring system is located in the chute or ground dispatching and command center to monitor the operating parameters and operating environment of the coal mining machine. The coal mine goaf refers to the void or cavity left after the underground coal or coal gangue is mined during the coal mining operation. When work continues near the goaf, it may cause hazards such as collapse. Therefore, it is necessary to monitor and manage the coal mine goaf.

[0003] With the rapid development of computer technology, communication technology, and automation technology, a good technical guarantee has been provided for the realization of centralized control and management of mine transportation systems. The system mainly consists of an underground main control machine and an intrinsically safe color display, a variety of belt protection modular sensors, and a ground control computer. The various belt protection modular sensors are electrically connected to the underground main control machine using a bus interface. The underground main control machine unit communicates with the ground control computer. In the underground main control machine unit, the monitoring software solidified by the host computer is used. Under the unified control of the central computer, the ground realizes remote automatic monitoring and control of the underground belt transportation system of the coal mine, and the remote dynamic monitoring function of the data, including the collection and transmission of the operating status of each device and various protection signals. The system has the functions of automatic fault information processing, time prompts, intelligent fault memory, visualization of query system log events, and automatic belt structure reconstruction. At the same time, it has the functions of fool-proof host computer construction platform, local area network monitoring, and fault alarm SMS notification. Summary of the invention
