Embodiment Construction

[0013] See attached picture.

[0014] The automatic recognition method of air traffic control radar data is developed and realized by using Visual C++6.0 on the Windows operating system platform. Complete the synchronous-asynchronous conversion of the received air traffic control radar data through the protocol conversion equipment, and input the asynchronous data into the air traffic control radar data automatic identification method software. The inventive software will identify according to the following steps and rules. After the identification is completed, Output the ATC radar data format type, and give the track / track characteristics of the report.

[0015] (1) Through the check code, identify the radar format of the special check method.

[0016] The WestingHouse radar format uses odd parity, the lower 12 bits are data, the 13th bit is odd parity, and the other high bits are not used.

[0017] The Toshiba radar format uses CRC16 checksum, and the checksum polynomial ...

Abstract

The automatic identification method of air traffic control radar data involves air traffic automation. It is to classify the air traffic control radar data according to whether the length of the message is fixed and the verification method adopted in the radar message to judge the format of the radar data and distinguish the dots and traces of the radar report. /track type. Whether the packet length is fixed or not is divided into two types: target packet length variation and fixed format and length. According to the verification method adopted, it is divided into two types: using CRC verification mechanism and using non-CRC verification mechanism. In the radar data whose target length changes, the radar data format is further analyzed and the track/track type is reported according to the internal structure difference of the message. This method simplifies the configuration of access radar parameters, reduces the problems of automation systems caused by configuration errors, and provides access conditions for the realization of radar data networking and control automation system expansion in the future. It can be widely used in the front-end access equipment of the air traffic control automation system, and has broad application prospects.

Description

Technical field [0001] The invention relates to air traffic automation, in particular to an automatic identification method for air traffic control radar data connected to an air traffic control automation system. Background technique [0002] The ATC radars currently used in my country's civil aviation system include Raytheon, Thomson / Thales, Alenia, Toshiba, NEC, Telephonics, WestingHouse, Siemens and other systems, from many different manufacturers. However, each manufacturer does not have a unified air traffic control radar data interface control file, which causes different data formats to be used by different air traffic control radars, and causes adaptability problems for the access equipment of the control center automation system. For each control automation system supplier, before connecting the air traffic control radar signal to the system, it is necessary to clarify the format of the air traffic control radar connected to the system, and decode the message accor...
