Abstract

The invention is applied in the field of airfield equipment, and provides an aerobridge and a control circuit thereof. The aerobridge comprises a single-phase UPS power supply which is used for supplying power when a normal power supply fails; a frequency converter which is used for receiving a control signal and driving a travel motor to realize emergency evacuation; a programmable logical controller which is used for sending the control signal to activate the emergency evacuation function of the frequency converter, and a fourth control switch which is used for controlling whether to trigger the emergency evacuation function of the frequency converter or not. The aerobridge adopts the single-phase UPS power supply to power the frequency converter when the normal power supply fails, and uses the programmable logical controller to control a logical terminal of the frequency converter and activate the emergency evacuation function of the frequency converter; therefore the aerobridge isenabled to evacuate 4 to 6 meters away from the plane so as to ensure the safe take-off of a plane; and simultaneously the single-phase UPS power supply has low cost, low weight and convenient installation and use.

Description

technical field [0001] The invention belongs to the field of airport equipment, in particular to a boarding bridge and a control circuit thereof. Background technique [0002] The boarding bridge is the bridge connecting the aircraft and the terminal building, and provides a wind and rain shelter for passengers entering and leaving the airport. When the passengers have boarded the plane, if there is an emergency power failure of the power supply of the boarding bridge, in order to make the boarded plane take off safely, the boarding bridge connected to the plane needs to be automatically retracted and evacuated for a certain distance. In order to ensure that the plane takes off normally. [0003] When an emergency power failure occurs and the normal power supply fails, the boarding bridge connected to the aircraft cannot automatically evacuate the aircraft. The existing technology can use a three-phase uninterruptible power supply (Uninterruptiable Power Supply, UPS) supp...
