The invention discloses a circuit control system of a boarding bridge, the boarding bridge and an emergency bridge withdrawing control method. The circuit control system comprises a PLC control loop, an emergency bridge removal control loop, an execution loop and a change-over switch. The PLC control loop comprises a PLC control chip and is used for outputting a control signal for a walking system of the boarding bridge; the emergency bridge withdrawing control loop comprises an emergency bridge withdrawing control module which is used for outputting an emergency bridge withdrawing control signal to the walking system; the execution loop acts on the walking system and works according to a control instruction for the walking system; the change-over switch comprises a first connection state and a second connection state. Wherein when the change-over switch is in a first connection state, the PLC control loop and the execution loop are conducted; and when the change-over switch is in the second connection state, the emergency bridge removal control loop and the execution loop are conducted. According to the invention, the control source in the normal mode and the control source in the emergency mode are switched in an electric control mode through the change-over switch, external dragging equipment is not needed, and rapid emergency bridge withdrawal can be realized.
本发明公开了一种登机桥的电路控制系统、登机桥和应急撤桥控制方法。电路控制系统包括PLC控制回路、应急撤桥控制回路、执行回路和切换开关。PLC控制回路包括PLC控制芯片,用于输出对登机桥的行走系统的控制信号;应急撤桥控制回路包括应急撤桥控制模块,用于输出对行走系统的应急撤桥控制信号;执行回路作用于行走系统,并依据对行走系统的控制指令工作;切换开关包括第一连接状态和第二连接状态。其中,当切换开关处于第一连接状态时,PLC控制回路与执行回路导通;当切换开关处于第二连接状态时,应急撤桥控制回路与执行回路导通。根据本发明,通过切换开关以电控形式切换常规模式与应急模式下的控制源,无需外部拖拽设备,可以实现快速应急撤桥。
