Aerobridge control system

The invention relates to an aerobridge control system which is used for controlling the movement of an aerobridge. The aerobridge control system comprises an operating mechanism, a control unit, a drive unit and an executing mechanism which are sequentially connected, and also comprises a safety protecting device which is connected in series between the control unit and a drive unit, or between the drive unit and the executing mechanism, or is arranged in the drive unit. The aerobridge control system determines the working state of the executing mechanism according to the state information given by the operating mechanism, and leads the working state of the executing mechanism to synchronize with the state information given by the operating mechanism. The safety protecting device is a safety relay or a safety contactor. The invention can realize that at lower cost: the aerobridge is simply lifted and/or stopped running by the operation of a button or handle when output contacts of a PLC adhere and a lifting contactor adhere or output wires of a transducer occur in failure.
