Multivariate operation information association method suitable for abnormal status information of connecting flights

Abstract

A multivariate operation information association method suitable for abnormal state information of connecting flights. It includes obtaining flight identification information, flight status information, estimated takeoff / landing time, actual takeoff / landing time based on flight plan, monitoring, and real-time data; judging whether the current flight is a direct flight; calculating the multivariate operation status information association of direct flights Judgment threshold; determine whether the current flight is a connecting flight; calculate the judgment threshold associated with multiple operating status information of the connecting flight; judge whether there is a unique flight plan data within the judgment threshold range at the time of receiving monitoring data; obtain the flight plan data if the judgment condition is met , surveillance data, real-time data associated information, otherwise record flight identification information and judgment threshold. The method of the invention is applicable to the information association when the state information of the connecting flight is abnormal and the actual take-off / landing time is missing, and improves the accuracy of the information association of multiple operating states of global flights.

Description

technical field [0001] The invention belongs to the technical field of aviation automatic control, and in particular relates to a method for associating multivariate operation information applicable to abnormal status information of connecting flights. Background technique [0002] The Civil Aviation Administration of China proposed to improve the global tracking and monitoring capabilities of China's civil aircraft. In order to meet the urgent needs of global tracking of civil aircraft in my country, a global flight tracking system has been developed and has been successfully operated online, and the real-time tracking of civil aviation transport aircraft in my country and overseas civil aviation transport aircraft has been initially completed. The normal operation of the global flight tracking system relies on the support of multiple operating status information. The types of information include planning information, monitoring information and real-time information. In act...

Problems solved by technology

The association method of fuzzy comprehensive function is based on the principle of maximum comprehensive similarity and threshold discrimination in fuzzy mathematics, and is suitable for dense target environments with large errors under limited conditions. The disadvantage is that this method uses a simple three-stage (climb-cruise-climb) flight The model deduces the planned trajectory, and the actual flight take-off / landing phase follows the standard entry / departure procedures, which does not match the actual flight situation of the flight, and cannot achieve fast and accurate association during the flight take-off phase

The association method of point pattern matching is based on the association matching of two point sets, which can reduce the dependence of matching results on single point information. The disadvantage is that this method can only process data normally when there are enough track points. In practical engineering applications, information There is a hysteresis phenomenon in association, and it is impossible to quickly match multiple operating status information

It can be seen that the existing technology can no longer meet the existing needs, so a new technical solution is needed to solve the above problems
