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...

[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...

[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...
