The invention discloses a power utilization information acquisition method based on object-oriented system architecture, comprising an electricity meter, an acquisition terminal and an acquisition system, the electricity meter and the acquisition terminal being connected through a terminal communication module, and the acquisition terminal and an acquisition system being connected through a communication channel; comprising the steps: 1), an acquisition system formulating a scheme and parameters to the acquisition terminal according to data service demands of an electricity meter, and the acquisition terminal executes an acquisition task according to the scheme to acquire data frozen on the electricity meter; 2), the acquisition terminal directly packaging a terminal protocol and actively reporting to the acquisition system, and analyzing and processing electricity meter data centrally by the acquisition system; 3), a terminal communication module supporting a dynamic learning mode and acquiring data; finishing data acquisition by a trail on multiple paths, and recording an optimal one. The method has the advantages that desired data items are added, decreased or altered at any time according to service needs and executive time, retry times and priority are altered according to data importance.
