Claim 9:
10. A system for compensating ultrasonic metering based on a smart gas Internet of Things system, wherein the system includes a smart gas user platform, a smart gas service platform, a smart gas device management platform, a smart gas sensor network platform, and a smart gas object platform that are connected in sequence;
the smart gas user platform is configured to send a query instruction of parameter management information of a gas device to the smart gas device management platform through the smart gas service platform;
the smart gas device management platform is configured to send an instruction for obtaining relevant data on the gas device to the smart gas object platform through the smart gas sensor network platform in response to the query instruction of the parameter management information of the gas device, receive relevant data on the gas device uploaded by the smart gas object platform; process the relevant data on the gas device to obtain management information of the gas device; upload the management information of the gas device to the smart gas user platform through the smart gas service platform;
the relevant data on the gas device at least includes a gas pipeline feature, a gas transportation feature, and an environmental feature, and the management information of the gas device at least includes a compensation scheme for compensating flow metering data of an ultrasonic metering device, and a process of determining the compensation scheme includes:
determining a first preset condition based on the gas pipeline feature obtained from an external database, and the first preset condition refers to a judgment condition for evaluating whether a flow compensation is required;
obtaining the gas transportation feature and the environmental feature based on at least one sensor; and
determining a compensation scheme based on the gas transportation feature, the environmental feature and the first preset condition, and the compensation scheme includes at least one of a flow rate compensation coefficient, a flow compensation parameter, a temperature compensation coefficient, or a pressure compensation coefficient, wherein the determining a compensation scheme includes:
in response to the gas transportation feature and the environmental feature satisfying the first preset condition, determining the flow rate compensation coefficient as the compensation scheme; and
in response to the gas transportation feature and the environmental feature not satisfying the first preset condition, determining the compensation scheme as a combination of the flow rate compensation coefficient and the flow compensation parameter.
