Embodiment Construction

[0031] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0032] Such as figure 1 As shown, a distributed multi-ground station ADS-B data fusion method includes the following steps:

[0033] (1) The ground station receives ADS-B data through the ADS-B receiving module.

[0034] (2) The ground station forwards the received ADS-B data to the data center.

[0035] (3) After receiving the ADS-B data, the data center first performs data verification through the data verification module. The batch processing of the data verification module is as follows:

[0036] (3.1) Take out the time stamp of the ADS-B data frame, and check the validity of the time stamp. According to the time accuracy of fusion, discard the data transmitted overtime, that is, the data with earlier time stamp.

[0037] (3.2) Check the validity of the ADS-B data frame to prevent data tampering.

[0038] (4) After obtaining valid ADS-B data in many p...

Abstract

The invention provides a distributed multi-ground station ADS-B data fusion method. The method comprises the following steps that (1) a ground station receives ADS-B data through an ADS-B receiving module; (2) the ground station forwards the received ADS-B data to a data center; (3) after the data center receives the ADS-B data, data verification ia made through a data verification module; (4) after effective ADS-B data is obtained in multiple places, the effective ADS-B data is sent to a data deduplication module for processing; (5) the ADS-B data by the sorting node is sorted by adopting algorithms such as a rapid sorting algorithm or a merging sorting algorithm and the like, and then the data is handled to a fusion data summarization module for processing; and (6) the fusion data summarizing module outputs the data, and the data is processed by other modules. According to the invention, a distributed architecture is utilized, ADS-B data of multiple aircrafts and multiple ground stations are fused, high-precision, low-delay and reliable ADS-B data is obtained, a data center has high-throughput and low-delay data processing capability, and resources such as calculation and storageare effectively utilized.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a distributed multi-ground station ADS-B data fusion method. Background technique [0002] With social progress and technological development, the number of civil aviation passenger aircraft continues to increase, posing severe challenges to civil aviation safety. As the basic guarantee of security, communication needs to be vigorously developed. In recent years, the Civil Aviation Administration has vigorously promoted ADS-B (Automatic Dependent Surveillance-Broadcast) technology, which is based on the global satellite positioning system, obtains relevant parameters from airborne equipment, and actively broadcasts the position of the aircraft to other aircraft or ground stations , altitude, speed, heading, identification number and other information, without manual operation or inquiry, for the controller to monitor the status of the aircraft. After the groun...
