Method for constructing virtual test environment of flight management system software

Abstract

The invention discloses a method for constructing a virtual test environment of flight management system software and belongs to the technical field of airborne system software testing. The method comprises the steps that first, comprehensive airborne electronic system network configuration containing a flight management system is constructed, and an interface associated with the flight managementsystem is constructed; second, a virtual target machine associated with the flight management system is constructed, an embedded operating system is formed, a simulation control and display module isconstructed according to the network configuration, an a peripheral device model base is constructed; third, fault models of all systems are established, and a dynamic link library is developed to form an interface associated with the flight management system and the embedded operating system; and last, an auxiliary test tool is integrated and used for performing black-box and white-box testing on the flight management system. Through the method, in the virtual test environment of system, flight management system airborne software configuration item testing can be completed independently andsufficiently without the influence of a real running environment of the flight management system.

Description

technical field [0001] The invention belongs to the technical field of airborne system software testing, in particular to a method for constructing a virtual testing environment for flight management system software. 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. The flight management system software (FMS software) realizes the centralized maintenance and management functions of each component system of the aircraft. [0003] At present, the research and development mode of flight management system software (FMS software) starts with the overall or general design of the software, and then starts the hardware equipment to reach the delivery status. Hardware system integration testing and validation. [0004] Since the flight management system software (FMS software) of the integrated avionics system has a great correlation with the hard...

Problems solved by technology

[0010] f) Or, it often occurs that the only set of real hardware environment is developing and verifying the function of a certain version of FMS software, and the state of another version of FMS software cannot be tested at the same time, which delays the testing plan and software product installation plan on time;

[0011] g) Or, the only physical verification platform in the laboratory is in the state of troubleshooting airborne equipment in the field, and the FMS software test cannot be carried out at the same time, which delays the test plan and software product installation plan on time;
