Description

technical field

[0001] The invention relates to a concentrator and its service method, in particular to a multi-access concentrator used in a gas system and its service method. Background technique

[0002] So far, automatic remote meter reading control system has been widely concerned and applied. Moreover, the Ministry of Construction stipulates that one of the necessary conditions for an intelligent community in the new era is a remote automatic metering system with three meters for water, electricity and gas. But for now, the application and feedback of the remote meter reading system that has been implemented are not optimistic. Various problems such as system instability, statistical data errors, equipment failures, and maintenance difficulties continue to emerge.

[0003] In the design of the repeater link, due to the diversity of user needs and applications of different implementation units, the design schemes of various domestic meter reading systems (which have b...
