(EN) The invention relates to the technical field of intelligent electric meters, and especially relates to an intelligent electric meter data storage method and device. The method comprises the followingsteps: acquiring power utilization data and recording time nodes corresponding to the power utilization data; reading preset reference time and an electric meter recording period; carrying out byte compression on the recording time nodes according to the preset reference time and the electric meter recording period to obtain a time index; and associating the power utilization data with the time index and then storing the data. By means of the method, the storage pressure of curve data is reduced, and due to the fact that the calculation mode of the time index is simple, data storage and data query can be conducted at a high response speed.
