The invention relates to a circulation cooling water secondary filter screen remote control apparatus and the method thereof, characterized by comprising: a differential pressure detection system, a gear motor, a sewage valve, an operator station and a distributed control system (DCS) wherein the DCS is connected together with the differential pressure detection system and the gear motor. The gear motor is connected with the sewage valve. The DCS and the operator station are mutually connected. And the DCS comprises a data acquisition module and a logic control module. The data acquisition module acquires the differential pressure detection system's signals and the gear motor's operational signals. The logic control module outputs the control commands for the gear motor and the sewage valve so as to realize the remote monitoring and controlling to a secondary filter screen system, therefore, increasing the operation efficiency of the system and reducing the devotion of human resources to the system.
