Claim 0:
1. A method for compensating ultrasonic metering based on a smart gas Internet of Things system, wherein the method is implemented based on a system for compensating ultrasonic metering, and the method is executed by a smart gas device management platform, comprising:
determining a first preset condition based on a gas pipeline feature obtained from an external database, wherein the first preset condition refers to a judgment condition for evaluating whether a flow compensation is required;
obtaining a gas transportation feature and an 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, wherein 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;
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; and
sending the compensation scheme to an ultrasonic metering device and controlling the ultrasonic metering device to determine updated flow metering data according to the compensation scheme.
