Embodiment Construction

[0012] A method for checking traceability of requirements of a civil aircraft flight control system, comprising the following steps, step 1: utilizing the requirement identification number rule in a specific civil aircraft control system, abstracting it into a regular sentence that can be expressed by a regular expression;

[0013] Step 2: Take the summarized regular expression sentence as input, and carry out software programming design in the python language platform;

[0014] Step 3: the software programming design includes simple design document selection, reading of document information, fuzzy retrieval of the read document information based on the re library, and output of retrieval results as text information;

[0015] Step 4: The obtained text information is the requirement identification number contained in the document, and the system-level and software-level requirements are connected and compared to check whether the high-level requirements are tracked by the low-le...

Abstract

The invention belongs to the technical field of civil aircraft flight control system inspection, and particularly relates to a civil aircraft flight control system demand tracking inspection method. The method comprises the following steps: firstly, abstracting a requirement identification number rule in a specific civil aircraft flight control system into a regular statement which can be expressed by a regular expression; Secondly, the summarized regular statements serve as input, software programming design is carried out, and a retrieval result is output as text information; And finally, performing link comparison on demand identification numbers in the text information according to system-level and software-level demands, and checking whether high-level demands are tracked by low-leveldemands or not. According to the method, convenience is provided for development and verification personnel to quickly extract the required identification numbers from the design documents and the models, and errors caused by manual inspection can be avoided in the whole inspection process.

Description

technical field [0001] The invention belongs to the technical field of civil aircraft flight control system inspection, and in particular relates to a method for traceability inspection of civil aircraft flight control system requirements. Background technique [0002] In the design and development process of the civil aircraft flight control system, it is necessary to itemize the requirements in the design process and track them from top to bottom according to the airworthiness requirements, so as to ensure that the top-level requirements are truly realized in the design. In the process, the inspection of a large number of requirements and their link relationships will consume a lot of time and energy for developers. It is necessary to develop a tool that can identify requirements retrieval and inspection in the process of development and verification to assist development and verification personnel to improve work efficiency and reduce the possibility of errors.
