Embodiment 1

[0032] Example 1. Radar data adaptation of the HDLC protocol, see Figure 4 .

[0033] The process of the main program searching and identifying HDLC procedures and completing the asynchronous transmission by the HDLC module is:

[0034] The free word of HDLC is 01111110B of 1 byte (8-bit binary), that is, 7EH in hexadecimal, that is, there is at least one free word 7EH between two messages. Therefore, the header and tail of a message are the idle words 7EH, and the effective content of the message is non-7EH data between two groups (at least one) of idle words.

[0035] In the main program, press 7EH to search and identify the HDLC type. Once the identification is correct for 3 or more consecutive times, enter the HDLC module program, search for the HDLC synchronous communication header 7EH, the effective data of the message and the trailer 7EH, and combine the combined The effective data of the air traffic control radar message is sent out by byte through the asynchronous...

Embodiment 2

[0037] Example 2. Radar data adaptation for IBM dual synchronization and the old Thompson procedure, see Figure 5 , 6 , 7.

[0038] The main program searches and identifies IBM double synchronization and old Thompson procedures, and the process of IBM double synchronization and old Thompson modules completing asynchronous transmission is:

[0039] The idle word of IBM double synchronization and old Thompson is 11111111B of more than 3 bytes (8-bit binary), that is, hexadecimal 0FFH, but IBM double synchronization has 2 bytes of synchronization word 32H before the formal message data, The old Thompson only has 1 byte of synchronization word 32H before the official message data. Therefore, the header of a message is the idle word 0FFH + synchronization word 32H, and the tail is 0FFH with more than 3 idle words. The data in between is the effective content of the message.

[0040] In the main program, search and identify the IBM double synchronization and old Thompson type a...

Embodiment 3

[0042] Example 3. Adaptation of radar data for WestHouse procedures, see Figure 8 .

[0043] The process of the main program searching and identifying WestHouse procedures and WestHouse modules to complete asynchronous transmission is:

[0044] The idle word of WestHouse is quite special, which is 13-bit binary number 0111111111110B, and the content of the message is also 13-bit binary number, which is a standard word length. At the same time, there is at least one free word 0111111111110B between two messages. Therefore, the header and tail of a message are also the free word 0111111111110B, and the effective content of the message is between two groups (at least one) free word. Non-011111111110B data.

[0045] In the main program, search and identify the WestHouse type according to 0111111111110B. Once the recognition is correct for 3 consecutive times (or multiple times), enter the WestHouse module program and search for the WestHouse synchronous communication header id...

Abstract

A data adapting method of air-control radar with different communication regulation includes setting synchronous clock input interruption service program of radar data and using air-control radar dataas data bit stream being red into processor bit by bit and entered into master program, confirming relevant radar data message structure and carrying out message combination by master program according to character byte of various radar data then transmitting combined message to ATC system in standard data communication mode of unified RS-232 asynchronous communication.

Description

1. Technical field [0001] The invention relates to the field of air traffic control, in particular to an adaptive adaptation method for air traffic control radar data of different communication regulations. 2. Background technology [0002] Multi-radar fusion technology is used more and more in the field of air traffic control, and a large amount of radar data needs to be transmitted to the air traffic control system, that is, the ATC system for multi-radar data fusion. At present, radar data in my country's air traffic control field are basically transmitted by synchronous serial communication, and radar data enters the ATC system through the synchronous serial universal interface. Since the synchronous serial universal interface can only receive and process the data of HDIC and IBM dual-synchronous communication procedures, and there are many types of radars currently used in the air traffic control field in my country, the data communication procedures do not fully comply...
