The invention relates to a handheld terminal-based collecting and recording method of metering devices of a user site. The method is technically characterized by including a collecting and recording method of a newly installed metering device of the user site and a collecting and recording method of an abnormally changed metering device of the user site. Data source uniqueness checking is realizedthrough a manner of dual checking-on of a handheld terminal and on-site artificial verification and user number association, and the handheld terminal stores information of equipment and the like through barcode scanning, identification and comparison to form a data intactness pair with a marketing business application system. At the same time, personal information of a user is confirmed throughelectronic collecting and recording of the handheld terminal, disadvantages of non-easy saving and the like of paper archives and the like are circumvented, work efficiency is effectively improved through advanced technology of fingerprint scanning and the like, system inputting of installation information is facilitated, production costs are reduced, risks of base archive unreality and the like are effectively prevented, paper waste can be reduced at the same time, resources can be saved, and occurrence of risks and hidden troubles of omissions, missing and the like of artificial verificationand recording can be effectively avoided.
