After landing each aircraft, people will always see one or more boarding bridges with a length of more than 10m to 30m slowly sliding and adjusting telescopically until they are close and precisely align the access doors. The "driver" acts as a driver on the operating console. Have you ever thought that the boarding bridge can also be unmanned?
In October of this year, CIMC Tianda Airport Equipment Co., Ltd. ("CIMC Tianda"), a subsidiary of CIMC, signed a contract with Amsterdam Airport in the Netherlands. The former will complete the development of the world's first driverless smart boarding bridge. Recently, the first prototype of this product was successfully tested at the Shenzhen CIMC Airport Base. Both parties are discussing the commercial process. It is expected that the first batch of unmanned boarding bridges will be used at the Amsterdam airport by the end of 2019.
Drivers need to break four core technologies
With the improvement of the equipment automation requirements of the airport industry and the demand for reduced labor costs, whether boarding bridges can be drone-free and automatically docked becomes a challenging problem for the boarding bridge industry.
From artificial control to machine self-driving, the difficulty of docking will increase by several gradients. "How to balance the motion inertia of such a large bridge from motion control requires a large amount of basic data verification to optimize the motion control method," said Liang Lexian, deputy general manager of the operation division of CIMC Tianda.
Liang Lexian told reporters that in order to achieve driverless driving, boarding bridges mainly need to break through four core technologies: First, the machine vision door identification technology, mature technology to achieve all-weather accurate and accurate in all kinds of complex conditions Reliable identification and positioning. Second, real-time path planning technology. After the boarding bridge recognizes the goal of the cabin, it needs to perform optimal path planning for the path. Third, it is a high-precision motion control technology. After the route planning, real-time conversion is needed. The control algorithm ensures that the boarding bridge automatically adjusts the direction and height, and accurately docks the aircraft cabin doors. The fourth is the intelligent collision avoidance technology. This requires smart hardware and software recognition technology to achieve intelligent collision avoidance and avoidance of aircraft and adjacent obstacles, and automatically bypass. Obstacles, the last "gentle" docking cabin doors.
In the international market, CIMC Tianda boarding bridge products have accounted for more than 40% of the total, covering more than 200 airports in 69 countries or regions. The comprehensive breakthrough of the above four core technologies has enabled CIMC Tianda to successfully develop the unmanned boarding bridge for the first time in the world.
Global Application and Verification Lead to Industrialization
These "black technologies" are not full-fledged technologies. In recent years, CIMC, headquartered in Shenzhen, has successively attempted to apply and verify the above-mentioned core technologies in boarding bridges at airports such as Amsterdam Airport in the Netherlands, Dubai Airport in the United Arab Emirates, and Hongqiao Airport in Shanghai. The smart boarding bridge has been completely broken and it has reached the stage of reliable integrated application.
It is understood that after the realization of the driverless boarding bridge technology, the operator only needs to set up the program in the system, remotely press the execution key, and the boarding bridge can automatically and safely dock with the aircraft cabin door. This will reduce the time required for the boarding bridge to dock from 3 minutes to 1 minute to speed up boarding bridge operational efficiency and efficiency of turnaround. At the same time, the application of technology will greatly reduce the number of on-site operators and increase the level of intelligence. The benefit of overall airport operations is due to improved efficiency and reduced costs.
“Intelligent boarding bridge for unmanned vehicles integrates an intelligent data management system, which can analyze data anomalies so that boarding bridge managers can master the overall state of boarding bridges in real time and predict the occurrence of failures in advance to maintain the equipment. Prepare." Liang Lexian said.
The research and development of these technologies has also attracted much attention both at home and abroad. In October 2017, the unmanned bridge of CIMC Tianda won the first order contract of the Dutch airport. According to CIMC, airports from Norway, France, the Middle East and other parts of the world also showed cooperation intentions. The relevant person in charge of the CIMC Airport Business stated that the development of the global aviation industry, especially the Chinese aviation industry, will be good, and technological upgrades and new technology updates will bring more potential markets.
Aviation intelligent market is promising
The intelligentization of boarding bridges is a microcosm of the era of aeronautical intelligence development. When the aircraft becomes more and more intelligent, the intelligent data docking and intelligent applications of ground aviation equipment will also be full of imagination. This reporter learned that apart from boarding bridges, CIMC's airport business covers almost all types of airport ground equipment. In recent years, CIMC's air cargo business has continued to show an upward trend. Last year, it achieved revenue of 3.2 billion yuan, a year-on-year increase. 14%.
At a meeting on December 19, the Ministry of Industry and Information Technology also said that the Ministry of Equipment Industry has accelerated the integration of new generation information technology and advanced aviation manufacturing technologies, vigorously promoted the innovative application of technologies and equipment, strengthened pilot operations, and promoted typical experiences. Effectively promote the intelligent transformation of the aviation industry.
At the China International Aviation and Space Summit held recently, industry sources said that "intelligence" has deeply affected the future of aviation. From budget research and development to trial production to stereotypes test flights, from the supply chain to the assembly line to the aviation city, from raw materials to product operations, everything requires the construction of a more scientific and efficient operating ecosystem, and the rapid evolution toward the direction of aviation intelligent manufacturing.
