US 12,723,960 B2 · Method and smart gas internet of things (IOT) system for determining gas metering strategies

Abstract

A method and a smart gas Internet of Things (IoT) system for determining a gas metering strategy are provided. The method includes: determining, based on time-dividing point correlation data, at least one group of candidate time-dividing points; determining, based on an assessment mode, an assessment result of the at least one group of candidate time-dividing points; determining, based on the assessment result, the at least two time-dividing points, wherein the at least two time-dividing points form at least one group of time-dividing point groups; transmitting at least two sound waves of different frequencies at the at least two time-dividing points and receiving at least two echo signals; determining, based on the at least two echo signals, a gas flow difference; determining, based on the gas flow difference, whether a noise interference exists; and in response to a determination that the noise interference exists, adjusting the gas metering strategy.
