基于 MBSE 和 VAPS 的民用直升机显控系统设计与验证

Aiming at the challenges of difficulties in tracing requirements, detecting interaction design defects, and achieving early system design verification, this paper proposes a design and verification for the display and control system (DCS) of civil helicopters based on model-based systems engineering (MBSE) and VAPS. The method begins with capturing stakeholder requirements to form system requirements, followed by the allocation of these requirements to system use cases. Black-box activity diagrams and sequence diagrams are constructed to conduct "requirement-function analysis" from the top down, describing the functional flow of the DCS. A running black-box statechart diagram is further established to verify the rationality of functional logic design. Based on the black-box functional architecture, the DCS architecture is developed, with iterative optimization of the allocation scheme through pilot communication. Functional activities from the black-box activity diagram are allocated to subsystems to achieve functional cascading, ensuring coherence throughout the design process. Pilot operation procedures are developed using the VAPS human-machine interface design tool, verifying the consistency of requirements, functions, and logic as well as the rationality of the architecture. This process achieves comprehensive coverage from requirements design to verification.
