Description

Technical Field

[0002] With the advancement of modernization and the rapid development of urbanization, the utilization rate of gas pipelines and manholes has increased. Pipeline gas leaks or cuts or explosions of flammable and explosive gases in manholes occasionally occur. Routine inspections are manual inspections, but manual inspections are delayed and costly, so automated monitoring has become a strong demand for monitoring the safety of public facilities. Traditional automated monitoring instruments often only focus on the monitoring function of parameters, ignoring the safety of the equipment and the convenience of installation.

[0003] In actual applications, due to the complexity of the monitoring site environment, the monitoring instrument often faces security risks such as damage, theft and removal. If the monitoring instrument is damaged, stolen or removed, the backend cannot be informed in time, and the monitoring site will be in a monitoring vacuum. At this time, once an incident such as pipeline gas leakage occurs, it will not be detected in time, which may lead to safety accidents.

[0004] At the same time, existing monitors are designed for a single application scenario, and are inconvenient to take and put during installation or replacement. In addition, when facing installation scenarios in different environments and locations, hardware, software, protection, structure, and other aspects may need to be improved, which cannot meet customer requirements well.
