Method for constructing virtual test environment of environment control system software

Abstract

The invention discloses a method for constructing a virtual test environment of environment control 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 an environment control system is constructed, and an interface associated with the environmentcontrol system is constructed; second, a virtual target machine associated with the environment control system is constructed, an embedded operating system is formed, a simulation control and displaymodule is constructed according to the network configuration, and 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 environment control 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 environment control system software. Through the method, in the virtual test environment or system, environment control system airborne software configuration item testing can be completed independently and sufficiently without the influence of a real running environment of a 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 environment control 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 environmental control system software (ECS software) realizes the centralized maintenance and management functions of each component system of the aircraft. [0003] At present, the R&D mode of environmental control system software (ECS software) starts with the overall or outline design of the software, and then starts the hardware equipment to reach the delivery status, and then the software R&D and testing personnel carry out the software design and development and unit component testing, and the software Hardware system integration testing and validation.

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 ECS software, and the other version of ECS 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 ECS software test cannot be carried out at the same time, which delays the test plan and software product installation plan on time;
