Coal bed gas pressure monitoring system based on 6LoWPAN internet-of-things technology

Abstract

The invention discloses a coal bed gas pressure monitoring system based on a 6LoWPAN internet-of-things technology. The coal bed gas pressure monitoring system comprises an underground 6LoWPAN wireless sensor network, an edge router, the industrial Ethernet, an overground server, a monitoring computer and an intelligent terminal; the underground 6LoWPAN wireless sensor network is connected with the edge router; the edge router is connected with the overground server through the industrial Ethernet; the monitoring computer and the intelligent terminal are connected with the overground server through the internet, and data is obtained from the overground server; the 6LoWPAN wireless sensor network is internally provided with several pressure monitoring nodes. By means of the coal bed gas pressure monitoring system, each measuring point serves as a node of the wireless sensor network, a mesh network is built in an Ad-Hoc network mode, the whole working section is subjected to data interconnection, through an underground main unit, data is uploaded in real time, the data collection precision is high, and the instantaneity and the safety are high.

Description

technical field [0001] The invention relates to the technical field of coal seam gas pressure monitoring, in particular to a coal seam gas pressure monitoring system based on 6LoWPAN Internet of Things technology. Background technique [0002] The development of wireless sensor networks and the rise of the Internet of Things industry have made it possible for a large number of wireless sensor networks to access the Internet. The current Internet of Things technology has been widely used in social life, providing great convenience for people's life and work. [0003] In the field of coal mine safety, the governance of coal seam gas has always been the top priority of safety work. Methane gas is the main cause of coal mine safety accidents in recent years. With the increase of coal mining depth, the gas content is also increasing. At present, the measures taken by the coal industry are mostly drainage or drainage. During the process, the pressure value of the drainage hole is...

AI Technical Summary

Problems solved by technology

[0004] At present, coal mine production units mostly use pointer pressure gauges to measure the pressure at the sealing point. The measurement accuracy is low, and it cannot meet the judgment of stable pressure.

To a large extent, the pressure result depends on the judgment of the workers. There will be large errors in the measurement results, and the measurement results have a large lag. When the pressure exceeds the limit, the results cannot be fed back in time, which will pose a threat to coal mine safety.

The mining area of ​​the underground coal seam is large, and there will be misreporting and missing reporting by manual transcription, and the drainage holes are widely distributed, and the workload is heavy, which greatly tests the patience and physical fitness of the underground workers
