A method and system for ensuring gas safety in key locations Technical Field

[0001] This invention relates to the field of gas safety assurance technology, and in particular to a method and system for ensuring gas safety in key locations. Background Technology

[0002] With rapid urbanization, gas safety issues are becoming increasingly prominent, especially in densely populated key locations where the importance of gas safety is self-evident. However, traditional gas safety assurance methods suffer from problems such as low efficiency, poor real-time performance, and difficulty in detecting potential risks.

[0003] (1) The internal space structure is complex, and the functional areas and renovations are frequent, which requires high on-site experience from management personnel. If management personnel are replaced, the cost of transmitting on-site information and data is high.

[0004] (2) In the actual operation and management process, due to problems such as “not being able to see clearly”, “not being able to find”, and “not being able to sort things out” in the operation and maintenance management of gas facilities, some safety hazards are not discovered in time and the elimination and rectification of hazards are not in place.

[0005] Currently, the technical means and management methods for ensuring gas safety in key locations are relatively simple, which may lead to some potential safety hazards not being detected and addressed in a timely manner, as follows:

[0006] (1) The internal spatial structure of key locations is complex, and the functional areas and renovations are frequent. In the actual management process, the gas system may have problems such as the pipelines not being visible and the system not being clear.

[0007] (2) The gas system in key locations is complex, which requires high on-site experience from management personnel. The cost of changing management personnel and transmitting on-site information and data is high.

[0008] Therefore, how to achieve comprehensive monitoring and early warning of gas safety in key locations has become a technical problem that urgently needs to be solved by those skilled in the art.
