An intelligent fuel gas safety metering system and a control method thereof relate to a fuel gas safety metering system and a control method based on wireless network and intelligent terminals. According to the invention, user terminal data are uploaded to a control center server at real time through graded network communication, and a control instruction sent by the control center server can be received. According to the method, information transmission is performed by wireless network, an intelligent terminal is used as an on-site decision control platform, and thus real-time uploading of fuel gas metering information and intelligent safety protection of user terminals are realized. Based on the method, a database can be established in the control center server to store and backup metering data, and data analysis and excavation can be performed based on the database, so as to finally realize system optimization. The system and method of the invention are in a safe and general integration mode, can guarantee safety in gas use, and have wide adaptability and flexible expansibility.
Description
technical field [0001] The invention belongs to the technical field of gas metering, and particularly relates to an intelligent gas safety metering system and control method based on a wireless network and an intelligent terminal. Specifically, user terminal data is uploaded to a control center server in real time through hierarchical network communication, and It can remotely receive the control instructions sent by the control center server to realize the control of the user terminal. Background technique [0002] At present, the metering principle adopted by the mainstream gas metering is based on the diaphragm gas meter. The diaphragm gas meter is equipped with a flexible film, which can expand and contract with the entry and exit of gas. A metering chamber is formed on both sides of each film. There is a sliding valve above the metering chamber, which can alternately connect the metering chamber with the inlet and outlet of the gas meter. When gas enters one metering...
