The invention relates to a fee control work order abnormity diagnosis and restoration method based on an acquisition operation and maintenance closed-loop management system, and the method comprises the following steps: (1) screening cost control detail data which does not generate a work order, and removing the data; writing the screened data into an intermediate table, calling an Oracle fee control generation and storage process, generating a work order, and solving the fee control failure details of 'omission' of an original interface; (2) scanning a charge control work order table of the closed-loop system at regular time; and (3) scanning a fee control task execution situation table of the mining system at regular time. The method is suitable for a power industry fee control management system, and after remote fee control fails, the execution of a collection operation and maintenance closed-loop management field fee control service is transferred, so that the integrity, real-timeperformance and timeliness of a closed-loop fee control work order are ensured.
