Embodiment 1

[0158] Embodiment 1: In step 2, the time synchronization operation is performed on the normal data output by different control centers through the least squares time registration method, and the process of time synchronizing the comprehensive data at different periods and at different times is: Assumption a, ( , is a natural number) is the adjacent control center, and its comprehensive track data output period is respectively and , and the ratio of the two is (n is a positive integer), if the control center a’s latest comprehensive track output time for the target state is ( , is a natural number), the next integrated track output time is , which means that the control center a between two consecutive outputs of the integrated track of the target state Have Secondary integrated track output. control center by the method of least squares of The second integrated track data is fitted into a virtual integrated track data as the first of the moment int...

Embodiment 2

[0175] Embodiment 2: The error processing in step 3 includes random error processing (random error can be well eliminated by the fusion algorithm during the fusion process) and system error processing. The random error is caused by the precision error factor of each monitoring equipment in the control center; the system error is caused by the coordinate conversion formula using the approximate algorithm and other factors. Random errors can be eliminated very well through fusion algorithms during the fusion process, while systematic errors are a kind of fixed errors that cannot be automatically eliminated by fusion algorithms. They must be estimated during the implementation process, and error compensation is performed on each control center to eliminate Registration error.

[0176] The systematic error is registered using the least squares method. The specific method is: within a period of time, the same target appears in the overlapping area of ​​the control areas of the two...

Embodiment 3

[0191] Embodiment 3: In the step 5, the integrated track data fusion of the normal data is carried out by using the federated filter no-resetmode (NR) algorithm, and the specific steps are:

Abstract

The invention relates to the field of control center data processing and especially relates to a method for integration processing of comprehensive track data. The method aims to solve the technical problem that the invention discloses a method for the integration processing of the comprehensive track data aiming at problems existing in the prior art, wherein flight tracks output by control center systems are integrated; flight plan tracks are established; relevant information is output according to demands of control centers; and thus comprehensive information integration among the control centers is realized. The method provided by the invention is characterized in that the data of each control center is analyzed and treated by time rectification, space rectification and quality analysis; then normal data, laggard data and abnormal data are processed separately; and thus the comprehensive track data integration is realized.

Description

technical field [0001] The invention relates to the field of control centerware data processing, in particular to a method for fusion processing of integrated track data. Background technique [0002] The automation system of the NAS system in the United States is a system of one manufacturer. The system is designed, integrated and operated in a unified manner. The FDP (flight data processor) data between ARTCC, TRACC and OCEAN is consistent and synchronized, information is automatically exchanged, and the system is tightly coupled. The new ERAM (EnRouteAutomationModernization ) as a model and an important support for NextGen. By formulating and establishing OLDI (On-LineDataInterchange) as a control transfer and data exchange protocol between control centers in Europe, and formulating technical standards and communication protocols for systems, interfaces and related systems, automatic control transfer, data synchronization and system interconnection have been realized. It...
