Claim 8:
9. A metering and correcting system for an ultrasonic gas meter based on smart gas Internet of Things (IoT), wherein the metering and correcting system for the ultrasonic gas meter based on the smart gas IoT comprises a smart gas user platform, a smart gas service platform, a smart gas device management platform, a smart gas sensing network platform, and a smart gas object platform connected in sequence;
the smart gas user platform is configured to send a query instruction of gas device management information to the smart gas device management platform through the smart gas service platform; and
the smart gas device management platform is configured to send instructions for obtaining gas device related data through the smart gas sensing network platform to the smart gas object platform in response to the query instruction of the gas device management information and receive the gas device related data uploaded by the smart gas object platform; process the gas device related data to obtain the gas device management information; and upload the gas device management information to the smart gas user platform through the smart gas service platform, or send the gas device management information to the smart gas object platform through the smart gas sensing network platform;
wherein the gas device related data at least includes ultrasonic data and gas medium data, the gas device management information at least includes a co-correction strategy for correcting the ultrasonic gas meter, and a process for determining the co-correction strategy includes:
in response to receiving a co-correction request from the ultrasonic gas meter, obtaining the ultrasonic data and the gas medium data, wherein the co-correction request is issued when a self-correction signal stability of the ultrasonic gas meter does not meet a first preset condition, and the self-correction signal stability is determined by the ultrasonic gas meter based on a self-correction strategy; wherein the self-correction strategy includes at least a self-correction algorithm and an algorithm depth, and the ultrasonic gas meter is configured to:
obtain a preset amount of reading data of the ultrasonic gas meter in a historical moment as a reading data set, the preset amount being related to the algorithm depth; and
determine the self-correction signal stability by the self-correction algorithm based on the reading data set;

determining a target signal stability value of the ultrasonic gas meter based on the ultrasonic data and the gas medium data; and
in response to the target signal stability value not meeting a second preset condition, determining the co-correction strategy.
