Software demand design verification architecture and method of airplane electromechanical management system

Abstract

The invention relates to a software demand design verification method for an airplane electromechanical management system. The method is suitable for verification of the software demand design of the electromechanical management system in the early stage of airplane detailed design. After the electromechanical management system software demand design is completed, an excitation system model and a response system model of the electromechanical management system are established by using interface generation software, a demand model of the electromechanical management system is established by using simulation software, and an electromechanical management system software demand verification test case is written. And according to the case operation excitation system model interface, whether the demand design is reasonable is judged by responding to the system model display interface so as to complete the demand verification work. Iteration and regression verification testing can be carried out on electromechanical management system requirements at the initial stage of airplane detailed design, parallel operation of design verification is achieved, the research and development period is shortened, meanwhile, design problems can be found as early as possible, system requirement optimization is carried out, and technical risks are reduced.

Description

Technical field [0001] The present invention relates to a software demand design verification method for aircraft electromechanical management system, which is applicable to the verification of the design of electromechanical management system software demand design in the early stage of the aircraft. Background technique [0002] The aircraft electromechanical management system is a distributed computer system for integrated management, automatic control, and fault monitoring. The electromechanical management system software is developed according to the functional requirements of the machine and electrical subsystem, embedding the airborne equipment to implement electromechanical management system function. [0003] In the current aircraft design process, electromechanical management system software demand is to coordinate with the supervisor of various machine design and electronic system, according to subsystem professional needs through electronic or paper documents, often u...

Problems solved by technology

However, whether the software requirements of the electromechanical management system are reasonable and perfect has not been effectively verified, but depends on the ability and experience of the software design supervisor and the supervisor of each electromechanical system, until the software and hardware are integrated and tested, that is, the electromechanical management system. The software requirements of the electromechanical management system can be verified only when the software development is completed and the C-type parts of the airborne equipment are delivered.

If the software requirements of the electromechanical management system are unreasonable, the subsequent iterative change cycle and cost will be very high

[0004] The aircraft electromechanical management system has many functions and complex data cross-linking. The development and verification of the electromechanical management system software requires a large workload and a long time-consuming cycle. The serial research and development model of "software development-software and hardware integration-functional verification" is undoubtedly more The R&D cycle is lengthened, and the work of the verification personnel is in the late stage of R&D. Not only the human resources are not fully utilized, but also the problem is found lagging behind, which brings huge risks to the model development
