Integration of Tower based on TOGAF Architecture
In order to solve the issues of towers that had repeated equipment and low-level information integration, a framework with three different views (physical, data, and application) based on the TOGAF concept was created, thus leading to modular components.
Such a system enables different business and technology scenarios to be handled in a flexible way and is thus a source of both cost savings and the creation of a digital transformation foundation.
Standardization of Information Exchange Interfaces
Interaction interfaces (e.g., flight data, parking stand allocation) were defined through the tower to the systems such as air traffic control automation and flow management in order to clarify the relations.
By defining the data formats and standards for cross-entity interactions, the inefficiency of "point-to-point" interaction disappears and the interoperability index of the systems increases.
Digital Display of Environmental Information
Based on fuzzy matching and intelligent learning, the integration, visualization, and interaction of meteorological data, dynamic intelligence, and work interfaces have been realized with the identification and matching rate of more than 80%, having the airport surface map as the background.
By means of digital twins, the overburden of air traffic controllers is being alleviated.
Surface Risk Prevention and Control Technology
Once the integration of air traffic control instructions (intentions) and target positions (situations) had been carried out, the conflict detection algorithms indicate the risk early warnings through the presentation along with the corresponding mitigation steps that are there for the controllers to help them in their decision-making.
The integrated tower system is mainly a physical layer safety measure.
It employs the most advanced technologies to penetrate the core issues and come up with a solution for integrating:
The Physical Layer combines the redundancy of the devices.
The Information Layer develops a common transfer platform.
The Function Layer provides modular support for the air traffic control of different scales.
Besides, it also deeply integrates the numerous systems such as electronic flight progress strips and digital air traffic control clearance.
It is now successfully managing the reduction of the workload and the increase of the operation efficiency after its implementation at Beijing Daxing International Airport.
Operation Monitoring
Operation monitoring includes two main parts: Sitiuation monitoring, which is a 2D/3D display of airspace, meteorological, and other information, and Capacity-flow analysis, which forecasts traffic flow on the basis of 4D trajectories and also points out over-capacity risks.
Pre-Tactical Management
Pre-Tactical Management provides an analysis of the operation of the next day, one to seven days ahead, and produces the flight adjustment plans by combining the weather conditions.
Tactical Management
Tactical Management generates traffic flow plans such as MIT (Miles-In-Trail) and GDP (Ground Delay Program), determines the time of takeoff (CTOT, Calculated Take-Off Time), and facilitates the flight operations, such as sequencing and exemption.
Post-Event Analysis
Post-event analysis helps to improve the implementation of the planned activities through collecting statistics of the operations (such as traffic flow, delays, etc.) and review analysis (production of reports based on archival data).
IV. Radio Monitoring Technology and Innovation
Key Technologies
To monitor different signals like VHF (Very High Frequency), radar, and GPS, they need to build portable dual-channel monitoring equipment.
This equipment is complemented by a data analysis platform (including GIS and SQL Server database) for data storage and representation.
Core Innovations
It radically changes the method of the dedicated radio open-field test for civil aviation by merging the traditional and dedicated monitoring and by changing the process from "post-event troubleshooting" to "preventive analysis."
After a region-wide deployment, the interference troubleshooting efficiency has been substantially uplifted (the monthly average number of interferences in this region was 47.7 in 2022).
V. Benefit Analysis
Social Benefits
By reducing the radio interference (which thus avoids ground-air communication interruptions and flight disorientation), flight safety is maintained.
It also measures the frequency usage to help solving the problem of the frequency resources shortage by providing necessary data (the number of air traffic control sectors will reach 587 by 2035).
Economic Benefits
By reducing the downtimes of the equipment, the stations will need to do costly electromagnetic surveys, which will cost them (approximately RMB 10,000 per station per year).
Once the station has the capability to do its electrical testing independently (RMB 50,000–80,000 per station is saved);
The technology can also be used in such areas as railways and radio, film, and television.
