1. A method for factory testing of a gas meter for production, wherein the method is implemented by a production management platform, the production management platform comprises a production data center, and the method comprises:
obtaining a type of a gas meter to be tested based on the production data center, wherein the type of the gas meter to be tested refers to different types of gas meters to be tested divided based on at least one of a model number, a range, or an accuracy;
determining at least one reference gas meter based on the type of the gas meter to be tested;
determining, based on historical application data of the at least one reference gas meter, predicted application data of the gas meter to be tested, the predicted application data including at least one of a predicted usage environment and a predicted usage intensity, the predicted usage intensity being determined based on at least one cumulative metering value of the at least one reference gas meter;
determining an application characteristic based on the predicted application data;
determining a predetermined test parameter, the predetermined test parameter including a plurality of test items and operating pressure ranges, temperature ranges, and gas flow ranges of the plurality of test items;
issuing a test instruction to control a production object platform to test the gas meter to be tested, the test instruction being determined based on the application characteristic and the predetermined test parameter, the test including at least one of a physicochemical characteristic test and a data transmission test; and
obtaining a test result based on the production object platform and determining a reliability score of the gas meter to be tested based on the test result and display data of the gas meter to be tested.
