Problems solved by technology

Testers manually test the communication node delay of the software under test, which is difficult to achieve tens of thousands of tests. When the parameters of the test case change, the test code needs to be modified, recompiled and run to get the test results, resulting in low test efficiency
Manually test the communication node delay of the software under test, which has limitations such as difficult operation, low test efficiency, inaccurate results and inconvenient observation

Abstract

The invention discloses an aviation airborne software interactive communication node time delay test tool which is high in time delay test efficiency and reliable in test accuracy. According to the technical scheme, test parameters are input into a communication window through a communication interface test interaction interface, and after a user inputs parameters of a communication node of a tested piece, communication node time delay is automatically generated; the data processing module 1 establishes corresponding test models for communication node time delay tests of different test requirements of airborne software, and the data processing module 2 further establishes a tracking relation model of the communication node time delay test requirements to generate a test case; a communication node test data packet is sent by test data of a tested communication node through a bus interrupt mechanism window, the data processing module 2 analyzes a received test instruction according to the received response number and the number of lost data packets, controls the transmission delay time, automatically generates a time delay test result between the tested communication nodes, and sends the test result to the communication node test module 2. And returning an interface communication test result to the software interaction interface.

Description

technical field [0001] The invention relates to the performance test of airborne software in the aviation field, and mainly relates to a time-delay performance test technology mainly used in the airborne software test communication node of the aviation airborne software, especially an interactive-based time-delay performance test tool of the airborne software communication node of the aviation airborne software. Background technique [0002] With the rapid development of aircraft flight control systems, avionics systems, and airborne electronic equipment, avionics full-duplex switched Ethernet (AFDX) has become the communication backbone of advanced civil aircraft avionics systems. The AFDX End System (ES) is an important part of the AFDX network. Airborne software is more and more widely used in the aviation field, but the security problems of aviation airborne software are also becoming more and more serious, and the performance requirements for aviation airborne AFDX netw...
