Embodiment Construction

[0080] The present invention will be further described below in conjunction with the drawings and embodiments.

[0081] The main process of the present invention is as figure 1 Shown.

[0082] Step 1: Establish a system requirement summary information model based on the panoramic view (AV)

[0083] Consolidate and summarize the concept, purpose, scope, and expected results of the civil aircraft cabin pressure control system, and establish a system requirements summary information package model (Package). Each package in the system requirements summary information package model is regarded as a level of the civil aircraft cabin pressure control system Requirement Diagram defined in SysML language is created in each package, and the ideas and expectations at the overall level of the system are written in the requirement diagram as a direction guide and modification plan at the initial stage of system development;

Abstract

The invention provides a civil aircraft in-cabin pressure control system modeling method, which comprises the following steps of: respectively establishing a system demand summary information model based on a panoramic view angle, a system demand analysis model based on a capability view angle, a system function analysis model based on an operation view angle and a system architecture model basedon a system view angle SV; combining a Harmony-SE method with a DoDAF system architecture to describe a cabin pressure control system model by using four perspectives of panorama, capability, operation and system on the basis of the hierarchy of system demand analysis, system function analysis and system architecture design. The design thought and concept description method of the cabin pressure control system model are provided by defining specific sub-views and model supplementation in each stage, meanwhile, the incidence relation between different views of the system is shown to a certain degree, and the design thought and development logic of designers are improved and completed.

Description

Technical field [0001] The invention relates to the field of aircraft design, in particular to a modeling method for civil aircraft. Background technique [0002] The basic task of the pressure control system in the cabin of a civil aircraft is to ensure that the cabin pressure and its rate of change meet the needs of the occupants for a more comfortable survival within a given flight altitude range, while ensuring the safety of the aircraft structure. The design of cabin pressure control system involves multi-disciplinary fields, interacts with many systems, and the realization of functions is becoming more and more complex. [0003] The traditional civil aircraft cabin pressure control system design is a text-based system engineering. The requirements and interactive information in the design process are recorded in text documents through natural language, and the documents are connected in series through a series of system terms and parameters. Flow between. However, this meth...
