Onboard central maintenance system software testing method and its system

Abstract

The invention relates to an onboard central maintenance system software testing method and its system and belongs to the field of design of onboard electronic systems. The onboard central maintenance system software testing method includes constructing a comprehensive onboard electronic system network configuration which comprises central maintenance system software and an onboard member system, setting connection relations of different ports, and carrying out interconnection through distributed simulation and verification data bus; building all fault models of a model base of peripheral equipment, selecting test case combinations and sending normal or fault data to the onboard central maintenance system software according to the test case combinations; carrying out contrastive analysis according to execution results and the test case combinations to determine whether function of the onboard central maintenance system software meets requirements or not. According to the system, the normal function model base of the peripheral equipment of the whole system is built and the fault model base is also built, effective cutting and optimizing or expanding is carried out according to other different types of airplane onboard electronic system configuration in the future, and thus, testing requirements of other onboard software can be met.

Description

technical field [0001] The invention belongs to the design field of airborne electronic systems, in particular to an airborne central maintenance system software testing method and system. Background technique [0002] Integrated avionics system software and hardware integrated design technology has been widely used in various types of modern military and civilian aircraft. Airborne central maintenance system software (OCMS software) realizes the centralized maintenance and management functions of each member system of the aircraft. [0003] The software functions of the airborne central maintenance system include: fault information processing; ground testing; status monitoring; software and hardware configuration management; data loading / unloading; airborne maintenance document index; flight support. The member systems of the airborne central maintenance system software management are composed of the following major categories of subsystems: avionics subsystems; electromech...

AI Technical Summary

Problems solved by technology

[0011] Or, it often occurs that the only set of real hardware environment is developing and verifying the functions of a certain version of OCMS software, and the other version of OCMS software cannot be tested at the same time, which delays the test plan and software product installation plan;

[0012] Or, the only physical verification platform in the laboratory is in the state of troubleshooting airborne equipment in the field, and the OCMS software test cannot be carried out at the same time, which delays the test plan and software product installation plan;

[0013] Furthermore, in view of the status of multi-version OCMS software installed in the field, fierce competition in test systems occurs at any time from all stages of development, testing, field troubleshooting, and internal and external testing
