Description

Technical Field

[0001] The utility model relates to the technical field of gas monitoring, in particular to an intelligent monitoring system for gas extraction. Background Art

[0002] The method of extracting gas from coal seams using special equipment and pipelines is called gas extraction. Gas extraction is an effective method to prevent coal and gas outbursts, reduce the gas content of coal seams, reduce the gas outburst in mining areas, and prevent gas from exceeding the limit during mining. It is the core of gas control and the fundamental measure to eliminate gas accidents and ensure safe production in coal mines. The gas extraction system is a fundamental measure to ensure safe production in coal mines, and gas extraction monitoring is an important means to ensure the normal operation of the extraction system.

[0003] In the existing intelligent monitoring system for gas extraction, it is not easy to accurately capture the concentration and environmental changes of various gases due to the different densities and distribution characteristics of different gases in the mine. The density of gas (mainly methane) is lower than that of air, so it usually accumulates in the upper part of the mine. The wind speed at different heights inside the mine can vary significantly, especially near the ventilation system. Monitoring is often fixed, which makes it inconvenient to adjust the height of the monitoring device, thereby reducing the monitoring efficiency.

[0004] For example, Chinese patent CN215932430U discloses an intelligent monitoring system for gas extraction, including active and standby redundant servers, which are electrically connected to a centralized control computer, a big data analysis computer, a large-screen monitoring, an APP monitoring and a cloud box; the active and standby redundant servers, the centralized control computer, the big data analysis computer, the large-screen monitoring, the APP monitoring and the cloud box are all electrically connected to a switch, the switch is electrically connected to a camera and a PLC, the PLC is electrically connected to an audible and visual alarm, a console, a sensor, a drain valve, a flow meter, an electric power parameter table and a butterfly valve, and an expansion board mechanism is provided on the side wall of the console.

[0005] The intelligent monitoring system for gas extraction has the following disadvantages: although the gas monitoring situation can be viewed in real time through computers and PLCs through network technology, real-time display, real-time alarm, real-time storage, and real-time query, due to the different densities and distribution characteristics of different gases in mines, it is not easy to accurately capture the concentrations of various gases and environmental changes. The density of gas (mainly methane) is less than that of air, so it usually accumulates in the upper part of the mine. The wind speed at different heights inside the mine will vary significantly, especially near the ventilation system. Monitoring is often fixed, which makes it inconvenient to adjust the height of the monitoring device, thereby reducing the monitoring efficiency.

[0006] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
