The air traffic management system is an important part of the air transport system, is responsible for preventing the aircraft and the aircraft collided, and air traffic smooth and orderly, charged with the important responsibility to protect the safety of the air transport system running. Civil Air Traffic Management System is in a period of strategic opportunities for building a new generation of air traffic control system, a phase of rapid development and management transition. Trend showing the continuing development of China's air transport, air traffic service support capability bottleneck effect is even more evident. To solve these security risks, and improve the level of safety management, Air tube must shift from the traditional experience of management systems security risk management, the establishment of the system of scientific, reasonable and feasible security risk. To create a security risk system to ensure air traffic safety, efficient, and orderly operation, control of run-time risk monitoring. Run in real time risk monitoring, including many respects, involving many factors, the Civil Aviation Administration of China Institute in the past few years, to carry out the control run the risk study based on actual operating data to the target track, the flight data, the low-altitude communications data basis for traffic control run risk communication risk, the risk of conflict in three aspects. Under the guidance of instructors, based on early research foundation, the paper mainly research focus based on the real-time control of interval running risk, through research and analysis of real-time interval data and quantitative the interval risk characterization parameters, to achieve the control run the risk of real-time monitoring. Analysis of the relative orientation between the three-dimensional space in the aircraft as well as running dynamic using MATLAB drawing tools and the Visual Basic programming language, through access to information, to determine the relative relationship between the interval and risk in the real-time operation. The research work includes the following aspects: (1) access to information at home and abroad to understand the depth of the Air Traffic Management industry for real-time risk assessment and risk running on air traffic management rules and regulations to understand the paper Writing to pave the way. (2) inspection the flight conflict as well as the collision probability-related information through the appropriate flight conflict detection method to determine the number of the aircraft that need to be considered in the real-time control. (3) In order to describe the degree of risk of conflict between the aircraft there is a potential risk, the paper introduces the concept of risk spacing and average risk spacing, used to describe the aircraft there is a potential risk of risk between the distance and the sector as a whole interval . And data fitting, initially identified the functional relationship between the average risk interval and safe operation of the risk. (4) using MATLAB's powerful graphics capabilities, combined with the conflict in the actual control of running sorties deployment difficulty coefficient relationship fit through the data to determine the functional relationship between the number of sorties that there is a potential risk with the safe operation of the risk. (5) the selection of the overall design of the control run security risk model and drawing tools based on real-time control interval. (6) visual programming tools using VB, to achieve overall display and verify the relationship between the real-time control of the interval with the safe operation of the risk-based.
