The invention provides an intelligent electric energy meter data diagnosis system and platform. Whether electricity data is accurate and timely and whether the electricity data meets a current data monitoring requirement are comprehensively judged by acquiring electric meter data, acquisition time and output voltage and output current data, judging whether the current acquisition time meets presetacquisition time and whether the current acquisition time and previous time form a time electric meter acquisition data link and also judging consistency with the electric meter data. Moreover, by aconvenient operation port and operation mode provided by the invention, the electric meter data of electricity users can be configured into electric meter data reports according to time periods or according to electricity use partitioning regions of the electricity users or according to important degrees of the electricity users, and be displayed on an electric meter data display module by a ladder diagram or a curve chart or a chart, so that monitoring personnel and the users sufficiently know an electricity use state of each electricity user.
