Now not only smart cars are conquering autonomous driving technology, but also many manned equipment are working hard, such as boarding bridges. According to the "Chengdu Release" public account,Recently, the world's first remote unmanned automatic boarding bridge (L4 boarding bridge) successfully completed its first passenger flight support mission.
This is the first time that unmanned aircraft landing equipment has been used in an airport around the world. It is also another major breakthrough made by Tianfu International Airport in the construction of "smart airports" after Asia's first fully automatic boarding bridge (L3 boarding bridge) was put into use at Tianfu International Airport in August last year.
It is understood that compared with the L3-level boarding bridge, the L4-level boarding bridge not only has a remote operation console, but also has a network dedicated to remote control and video surveillance, as well as many hidden "high-precision" technical blessings.
For example, in the flight guarantee process, a bridge permission button and boarding bridge status display are added, and a light curtain switch is added in the boarding bridge channel.It is used for real-time monitoring to prevent unauthorized persons from entering during the movement of the boarding bridge; the safety boots and rolling shutter doors of the boarding bridge are modified to be electric lifts, further improving the safety when docking with aircraft.
In addition, the anti-collision redundant design of various sensors such as ultrasonic, millimeter wave, and laser radar on the boarding bridge has also been greatly improved.Compared with traditional boarding bridges, it can more accurately detect obstacles around the boarding bridge and measure height, distance, angle and other data.
At present, Tianfu International Airport, with the strong guidance of the Sichuan Civil Aviation Administration and the support and cooperation of Sichuan Airlines, China Eastern Airlines and other airlines, has successively completed multiple aircraft door simulator docking tests and real aircraft no-load docking tests of the L4 boarding bridge, and compiled 6 technical documents such as docking test reports, bridge pickup and withdrawal procedures, emergency response plans, and trial operation safety management requirements, laying a solid foundation for the trial operation and later promotion and application of the L4 boarding bridge.
