Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of gas leakage monitoring, and in particular to a gas leakage monitoring method and system based on gas metering. Background Art
[0002] As an efficient and clean energy source, gas has been widely used in households, industries and commercial fields. However, gas leakage not only wastes resources, but more seriously may cause fire or explosion accidents, posing a huge threat to people's lives and property safety. Although the existing gas leakage monitoring technology has reduced these risks to a certain extent, it still has many shortcomings.
[0003] Traditional gas leak monitoring methods mainly rely on simple gas sensors and alarm devices. These devices can usually only provide basic concentration detection functions and are sensitive to environmental noise and interference, which can easily cause false alarms or missed alarms. In addition, many existing systems lack effective data processing capabilities and find it difficult to accurately extract useful information from complex data, which makes them inaccurate in identifying potential leaks. In addition, due to the lack of an intelligent alarm mechanism, once a leak occurs, relevant personnel are often not notified in time to take action, thus delaying the best time to respond. Therefore, we propose a gas leak monitoring method and system based on gas metering. Summary of the invention
