The invention discloses a multi-strategy electric meter daily freezing value automatic replacement method and device, and the method comprises the steps: responding to an electric meter daily freezingvalue replacement strategy setting instruction inputted from the outside, and obtaining the electric meter information in a corresponding instruction, a plurality of replacement strategies, and the priority information of the replacement strategies; acquiring daily frozen data acquisition information of the electric meter; responding to the abnormal daily frozen data in the daily frozen data acquisition information of the electric meter, and sequentially executing the daily frozen value substitution strategies of the corresponding electric meter from high to low according to the plurality ofsubstitution strategies and the priority information of the corresponding electric meter until the execution result of one substitution strategy can obtain the daily frozen substitution value of the corresponding electric meter; and recording the daily freezing replacement value obtained for the first time as the daily freezing value of the corresponding electric meter. According to the invention,multiple substitution strategies with different priorities which can be preset are utilized to realize automatic data substitution when the daily freezing value of the electric meter cannot be normally acquired, so that the normal statistics of various subsequent electric quantity data and the reliability of subsequent related calculation are ensured.
