Claim 7:
8. The IoT system of claim 7, wherein to determine the target gas meter based on current usage data and historical usage data of the gas meter reading information, the smart gas device management sub-platform is further configured to:
respectively construct a current usage vector and a historical usage vector database based on the current usage data and the historical usage data of the gas meter reading information;
determine whether there is a vector matching the current usage vector in the historical usage vector database; and
in response to the determination that there is not a vector matching the current usage vector in the historical usage vector database, determine that the gas meter corresponding to the current usage data is the target gas meter, and determine a suspicious score of the gas meter, wherein the suspicious score is positively correlated with a minimum vector distance of the current usage vector in the historical usage vector database.
