[0012] Working principle: Gas can be transported through gas pipelines, so that gas can circulate inside the gas meter. The gas usage is measured by the gas meter, and then recorded by mechanical counters and electronic counters, and then transmitted to the display screen for display through connecting wires. Then, the gas usage can be reported to the user and the gas company in a timely manner through the communication module. After installation, user information, gas usage information and address information are first collected, and the parameters of metering accuracy, flow limit and alarm threshold are set. Then, during normal use, the gas meter will collect user gas usage data in real time and transmit it to the management platform by the communication module, and then it will be managed in real time. The control module is used to control the switch of the gas meter valve. Abnormal situation control monitors abnormal gas usage through the control module. When abnormal gas usage is found, the communication module is used to alarm the management platform and automatically close the valve. The valve is closed for arrears and communicated to the management platform and users through the communication module. Maintenance and management control include remote maintenance command execution, local maintenance operation coordination, and closing the valve through the control module during data backup and recovery.

The gas sensor is electrically connected to the electronic valve through an electric wire, so that the electronic valve can be opened in time when a gas leak is detected, so that the carbon dioxide inside the carbon dioxide bottle is released in time, thereby achieving the effect of reducing the gas concentration, thereby reducing the probability of fire.

[0015] 3. In the present invention, multiple electronic counters are electrically connected by connecting wires and then connected to a display screen so that the gas usage of multiple users can be viewed through one display screen, thereby saving display resources.

In addition, it can also cooperate with the communication module to monitor the operating status of the gas meter and issue an alarm in time when a fault occurs, which is convenient for the gas company to carry out maintenance and management.

[0031] A gas meter control method for an IoT gas meter applicable to a multi-user scenario comprises the following steps: S1. User information entry and initialization: collect user information, gas usage information and address information, and set parameters for metering accuracy, flow limit and alarm threshold; S2. Normal gas consumption control: The gas meter 11 collects the user's gas consumption data in real time and transmits it to the management platform through the communication module; S3. Real-time control: The valve of the gas meter 11 is switched on and off through the control module.

[0032] Specifically, by collecting user information, gas usage information and address information, the user's gas usage data can be accurately obtained, providing a basis for gas companies to achieve accurate billing and tiered gas price management. At the same time, it can monitor the operating status information of the gas meter, facilitate timely detection of faults and arrange maintenance, and ensure safe and stable gas use. In addition, the collected information can also be used to analyze users' gas usage habits, and provide a reference for gas companies to optimize gas supply plans and improve service quality. By setting metering accuracy parameters, from a billing perspective, high-precision metering can ensure that gas companies accurately count users' gas usage, thereby achieving fair and reasonable charges and avoiding cost disputes caused by inaccurate metering. From a resource management perspective, accurate metering helps to accurately grasp gas consumption and provide data support for gas companies to reasonably allocate resources and optimize gas supply plans. From a safety monitoring perspective, accurate metering can more keenly detect abnormal gas usage, such as whether there is a potential leak, because even a small leak can Leaks may also be discovered under precise metering, which helps to take timely measures to ensure gas safety. By setting flow limits, it is possible to avoid safety accidents caused by excessive gas flow due to unexpected situations (such as pipeline ruptures, etc.). Reasonable control of gas consumption speed can also help maintain the stability of the gas supply system. By setting alarm thresholds, alarms can be issued in time when gas usage is abnormal. For example, when gas leaks or gas consumption in a short period of time exceeds the normal range, users and gas companies can be quickly notified, which is convenient for users to take emergency measures and for gas companies to conduct timely inspections and handling, effectively preventing the occurrence of gas safety accidents and managing gas usage in a more refined manner.

[0033] S3. Real-time control includes the following methods: Abnormal situation control: The control module monitors abnormal gas usage. When abnormal gas usage is found, the communication module is used to alarm the management platform and automatically close the valve. The valve is closed for arrears and the communication module is used to inform the management platform and users at the same time. Maintenance and management control: The valve is closed through the control module during remote maintenance command execution, local maintenance operation coordination, and data backup and recovery.
