Problems solved by technology

Among the existing conformance testing techniques, no more practical conformance testing technique for the VHF data link mode 2 air-ground communication system has yet been developed
However, the existing research results for this test technology are only applicable to the link management function in the test protocol stack part, and the method of simulating the underlying communication of the LAN is used in the test, which greatly changes the system under test, so it is only applicable to The link management function in the protocol stack function is verified during the development stage, but it cannot be actually used for the conformance test of the VHF data link mode 2 air-ground communication system

Abstract

The invention provides a method and system for consistency test of an air ground communication system, wherein the method comprises the steps of: generating a test frame according to a test command message input by a user; sending the test frame to a tested system; and receiving a response frame from the tested system and analyzing the response frame to obtain a test result. The invention realizes the consistency test of the VDL M2 air ground communication system through sending the test frame to the tested system and testing the consistency of the tested system according to the response frame condition of the tested system, can complete all the test functions via comprehensive test so as to test the real condition of the tested system, and does not need to reform the tested system, thereby being convenient and feasible.

Description

technical field [0001] The invention relates to a consistency testing method and system of an air-ground communication system, in particular to a consistency testing method and system of a VHF data link mode 2 air-ground communication system, belonging to the technical field of aviation communication. Background technique [0002] Very High Frequency Data Link (VDL: Very High Frequency Data Link) is one of the air-ground wireless communication data links commonly used in the international aviation industry. Among them, the VDL M2 is organized according to the open system interconnection standard model and designed for the air-ground subsystem of the Aeronautical Telecommunications Network (ATN), which is an important subnetwork of the ATN. . It is connection-oriented and bit-oriented, and its transmission capacity is 10 times that of the Aircraft Communication Addressing and Reporting System (Aircraft Communication Addressing and Reporting System, referred to as: ACARS) dat...
