Description

technical field [0001] The invention relates to a gas monitoring device, in particular to a manhole cover type gas monitoring device for gas monitoring in an underground pipe network. Background technique [0002] There are various pipelines underground in cities, including transmission pipelines for cable communication, tap water, rain and sewage, etc. The gas components in these pipelines are complex, and there may be flammable and explosive gases or gases that are poisonous to the human body, and these gases It is in a basically confined space, and the normal operation of these pipelines is closely related to our life. When a failure occurs, maintenance personnel are required to repair it immediately. Therefore, how to effectively monitor the gas in these pipeline networks is a must. an important public safety issue. [0003] However, the complex underground environment makes monitoring difficult. For example, if there is flammable gas, there will be a danger of explosio...

AI Technical Summary

Problems solved by technology

[0003] However, the complex underground environment makes monitoring difficult. For example, if there is flammable gas, there will be a danger of explosion, and toxic gas will cause physical injury or life threat to the maintenance personnel entering the underground pipe network; the lack of power will increase the monitoring The wiring cost of the instrument may make the working time of the monitoring instrument unguaranteed, or even the pipeline for conveying water may cause the instrument to be flooded, etc.; the installation and maintenance of ordinary monitoring instruments in underground pipelines are very inconvenient; On the one hand, if wireless communication technology is used, it is difficult to ensure the effectiveness of the transmission of monitoring signals located underground. If wired transmission technology is used, wiring is very inconvenient and the cost is high
