Method for evaluating network communication bandwidth required by monitoring information transmission between air traffic control systems

Abstract

The invention discloses a method for evaluating network communication bandwidth required by monitoring information transmission between air traffic control systems. The method comprises the following steps of: firstly, establishing network connection between a source system and a target system to be evaluated; embedding an evaluation program in the two-end system, wherein the evaluation program and the monitoring information processing program interact transmit-receive information through an interface; recording the transmit-receive message information and counting the point loss rate according to warehousing information; then, sending, by the evaluation program, a test message regularly and calculating time delay according to the storage time of a receiving and sending end, and calculating the time delay jitter by using a standard deviation method according to the time delay of a certain time; and establishing an air traffic control monitoring information transmission index, gradually reducing the inter-system bandwidth, and determining the required bandwidth when one of the time delay, the time delay jitter and the point loss rate does not accord with the index. By adopting the method, the communication bandwidth required for monitoring information transmission between air traffic control systems can be effectively evaluated, and a basis is provided for work such as communication infrastructure construction and monitoring information transmission effect evaluation in the air traffic control industry.

Description

technical field [0001] The invention belongs to the field of air traffic management, and relates to a network communication bandwidth evaluation method required for monitoring information transmission between air traffic management systems. Background technique [0002] China's civil aviation traffic control system, including air traffic control automation system, airport surface management system, ADS-B processing system, flow management system, etc., is responsible for information processing and air traffic control tasks. Taking the air traffic control automation system as an example, it has basically formed three Level air traffic control system, with eight regional control centers as the core, terminal (approach) control center as an important part, and airport tower as an extension of the system architecture, the "independent" automation system implementation technology has matured. [0003] In order to improve the automation and networking of air traffic control inform...

Problems solved by technology

[0003] In order to improve the automation and networking of air traffic control information processing, get rid of the status quo of independent operation, and realize the integrated management and sharing of data such as national air traffic control surveillance, flight plan, weather, and aviation information, it is the development trend of the air traffic control system. The interconnection between systems, the construction and upgrading of network communication infrastructure need to evaluate the required network communication bandwidth between systems, to ensure the stable and real-time information transmission, and to verify the effect of information transmission, but currently there is no effective method to monitor the communication bandwidth requirements. Calculation and evaluation, especially the air traffic control monitoring information with high real-time requirements
