Description

technical field [0001] The invention relates to the technical field of virtual integration testing of avionics systems, in particular to a model-based virtual integration testing method and system for avionics systems. Background technique [0002] Traditionally, software-in-the-loop is generally used to complete manual coding, so as to establish a digital avionics system simulation verification system; hardware-in-the-loop testing is an integrated testing method based on hardware test benches equipped with software Loading system testing field. After the system integrator obtains the equipment from the equipment or subsystem supplier, it needs to complete the synthesis of multiple equipment, and verify whether the interface and interaction logic between the equipment meet the design requirements; after that, it is necessary to complete the integrated system according to the system function requirements As input, the system-level functions are tested item by item to verify ...

AI Technical Summary

Problems solved by technology

Existing tool software focuses on studying the physical characteristics of system testing, but tools for special functional and logical characteristics of avionics systems are very rare, and conventional tools cannot implement early verification testing methods for model-based avionics systems

[0004] At the same time, there are still many limitations in the existing test methods. For example, the complexity of modern aircraft avionics systems is rapidly increasing. Facing hundreds of thousands of signal data interactions and avionics systems with thousands of data buses, the coded The workload is extremely huge, and traditional methods are even more stretched when requirements change rapidly and system failures continue to occur

In addition, in the process of system integration and verification of hardware-in-the-loop testing, problems such as large amount of testing of electronic interface communication protocols, low efficiency of manual testing, and complex dynamic cross-linking of system integration verification need to be solved.

At the same time, all model-in-the-loop tests at this stage are mostly closed-loop tests for a single model such as Simulink, which has the limitation of a single model type and is difficult to integrate

[0005] Therefore, the traditional methods of hardware, software, and model-in-the-loop testing cannot meet the early verification tests of avionics systems for verification requirements.
