Claim 2:
3. The method of claim 2, wherein the determining the target gas meter based on current usage data and historical usage data of the gas meter reading information comprises:
respectively constructing 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;
determining 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, determining that the gas meter corresponding to the current usage data is the target gas meter, and determining 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.
