Research On The Flight Plan Track Dependence Problems In ATC Automation Systems

With the rapid development of Chinese economy, in recent years the civil aviation flight increases rapidly, which give us the air traffic control unit brings hitherto unknown challenge. At the same time, the state has also increased the air traffic control system and facilities were put into the corresponding construction, domestic air traffic control automation system has gradually entered the mature stage. Due to the characteristics of domestic research and development of automation system with R&D units and the use units of common design, low cost, high security, scalability good advantage of it by a control center welcome.In the whole system of civil aviation, airspace is divided into several blocks, each of the small space belonging to different control center airspace air device management, interaction between the control centers through the telegraph to aircraft information. According to different types of message format provisions, ATC automation system control center can be extracted from the flight data in the received the telegram, the establishment of the aircraft flight plan, then the corresponding aircraft for the corresponding operation and display. The flight plan has14different states in the whole life cycle. System for processing the received message, according to flight data processing from the conversion of the original flight plan status within the system, thereby triggering the corresponding flight plan status operation.The development process compared with the imported ATC automation system for more than60years, domestic research of ATC automation system is still in the initial stage. ATC automation system technology is used mostly belong to the "take-ism", actually is to imitate imported automation system model for replication, many details do not meet the actual needs of work of China’s ATC operation.So the key technology is mainly related to the ATC automation system in the track of the author studied:Air traffic control automation system flight plan track dependence. The main research current ATC automation system flight plan related patterns, namely the SSR matching model. The SSR matching the specific process and operation method of mode flight plan and track automatic related, at the same time also describes the process of the artificial intervention.Research on how to improve the automatic flight plan track dependence accuracy. In this part, the author studies in detail about the flight plan and track dependence rate and correct rate to improve on the existing basis, presents a comprehensive consideration of the flight plan and track in time, space and direction of the comprehensive dependence degrees of the concept and its algorithm is given. The SSR associated with the comprehensive correlative degree with related model related to the rate of flight plan and track and correct dependence rate.According to the results of the simulation experiment. The method of rate and correct rate of increase in the proposed system is system simulation experiment. Through the simulation experiment results in this paper in the real production process, to improve the expected effect of flight plan and track correlation rate and correct rate, is of great significance in the improvement of work efficiency.
