[0054] In actual application, when the boarding bridge approaches the aircraft and prepares to open the weather door, the staff can send instructions through the remote control unit, and the PLC will transmit the signal to the PLC server module of the local control end, and then control the drive device of the door to open the weather door. During the opening of the door, the system will issue a "do not pass" voice through the voice prompt device, preventing personnel from approaching. At the same time, the state indicator light will display red, indicating that the door is in an operating state.

[0055] When the door is completely opened, the system detects the position of the door through the door opening sensor, triggers relay KC62 to be powered on, and issues a "passable" voice prompt through the public address speaker. The state indicator light changes to green, indicating that the door has been safely opened, and passengers and staff can pass through.

[0056] During the process of closing the door, the staff can issue a closing instruction through the local switch or the remote control unit, and the PLC controls the driving device to automatically close the door. During the process of closing the door, the voice prompting device will again issue a "no passage" prompt, and the status indicator light becomes red. When the door is completely closed, the door closing sensor triggers the relay KC61 to be powered, the indicator light becomes red, and the sound broadcast speaker stops the voice prompt.
