【摘要】：安全性是飛機的重要特性，它影響飛機和乘客的生命安全，是飛機的固有屬性。隨著飛機系統(tǒng)組成越來越復(fù)雜，以及飛行環(huán)境更加惡劣等多方面因素的影響，飛機的安全性工作變得更加重要，安全性已經(jīng)成為產(chǎn)品研制過程中必須開展的一項設(shè)計分析工作，貫穿了民機設(shè)計從概念設(shè)計到設(shè)計驗證的各個階段。 安全性設(shè)計分析在飛機研制的概念設(shè)計階段明確整級的安全性要求，在飛機初步設(shè)計階段明確系統(tǒng)級安全性要求并開展初步系統(tǒng)安全性評估工作，在飛機詳細設(shè)計階段和試驗驗證階段開展系統(tǒng)安全性評估，進行整機級和系統(tǒng)級安全性要求的驗證。它是一種針對提出的安全性設(shè)計要求與目標，通過系統(tǒng)的安全性分析方法驗證系統(tǒng)設(shè)計是否滿足安全性要求，并在分析過程中識別風(fēng)險并盡力采取措施來降低危險的系統(tǒng)分析方法，其業(yè)務(wù)流程實現(xiàn)了自頂向下安全性需求的識別和確認，以及自下而上安全性需求的驗證過程。 本論文主要研究的目標是解決企業(yè)現(xiàn)有安全性設(shè)計分析工作中存在的各類問題，形成適用于飛機及下屬各層級產(chǎn)品的數(shù)字化安全性分析系統(tǒng)，融合專業(yè)工具，通過有效工作任務(wù)管理實現(xiàn)過程管控，構(gòu)建相應(yīng)的知識庫為安全性工作提供數(shù)據(jù)支撐，從而實現(xiàn)管理融合、數(shù)據(jù)集成、工作協(xié)同，改變當(dāng)前獨立的安全性工作項目管理和分散的安全性信息管理現(xiàn)狀，，切實提高安全性分析工作效率。 本論文主要研究內(nèi)容包括： 首先，疏理民機安全性分析工作的核心業(yè)務(wù)流程，明確不同研制階段應(yīng)該開展的工作項目，確定系統(tǒng)整體的功能及性能要求，確認系統(tǒng)功能包含安全性工作任務(wù)管理、安全性設(shè)計分析、安全性知識庫管理、安全性數(shù)據(jù)分析和報告等模塊，實現(xiàn)安全性工作任務(wù)的發(fā)布、設(shè)計分析的執(zhí)行、信息查詢、信息監(jiān)控等功能。 其次，在技術(shù)層面上，此民機安全性分析系統(tǒng)是一個采用Windows平臺主流的解決方案.Net Framework4.5并基于客戶端/服務(wù)器（B/S）結(jié)構(gòu)的小型數(shù)據(jù)分析管理系統(tǒng)。該系統(tǒng)采用經(jīng)典的三層架構(gòu)進行設(shè)計即數(shù)據(jù)庫層、業(yè)務(wù)邏輯層和功能展示層，存儲并分析企業(yè)安全性設(shè)計分析的數(shù)據(jù)，以提高整體系統(tǒng)的可擴展性、靈活性、易維護性。 再次，系統(tǒng)采用基于WSDL協(xié)議的Webservice中間件實現(xiàn)與第三方系統(tǒng)的數(shù)據(jù)集成，將中間件部署到Web服務(wù)器上，各系統(tǒng)基于HTTP協(xié)議接入并實現(xiàn)數(shù)據(jù)通信。實現(xiàn)了安全性分析系統(tǒng)與企業(yè)已有PDM、P6、OA、可靠性設(shè)計分析系統(tǒng)的數(shù)據(jù)集成，實現(xiàn)統(tǒng)一數(shù)據(jù)源分析，保證與研制工作的協(xié)同。 本論文從民機安全性分析系統(tǒng)的實際需求出發(fā)，依托安全性工程體系的理論和軟件工程的方法進行系統(tǒng)分析設(shè)計，最終形成以工作流程為主線、以工程數(shù)據(jù)為驅(qū)動的實用安全性分析系統(tǒng)，經(jīng)過系統(tǒng)的測試驗證本系統(tǒng)目前可行，但隨著實際業(yè)務(wù)需求的增加，系統(tǒng)仍待優(yōu)化完善。
[Abstract]:Safety is an important characteristic of aircraft, which affects the safety of aircraft and passengers, and is the inherent attribute of aircraft. As the composition of the aircraft system becomes more and more complex and the flight environment becomes worse and worse, the safety of the aircraft becomes more and more important, and safety has become a design and analysis work that must be carried out in the process of product development. It runs through every stage of civil aircraft design from concept design to design verification. The safety design analysis defines the overall safety requirements in the conceptual design phase of aircraft development, and the system-level safety requirements in the initial aircraft design stage, and carries out the preliminary system safety assessment work. The system safety assessment is carried out in the detailed design stage and the test verification stage of the aircraft, and the safety requirements of the whole aircraft and the system level are verified. It is aimed at the proposed security design requirements and objectives, through the system security analysis method to verify whether the system design meets the security requirements, And in the process of identifying risks and taking measures to reduce the risk, the business process realizes the identification and confirmation of top-down security requirements, as well as the verification process of bottom-up security requirements. The main purpose of this paper is to solve the problems existing in the existing safety design and analysis of enterprises, to form a digital security analysis system for aircraft and its subordinate products, and to integrate professional tools. Through effective task management, process control is realized, and the corresponding knowledge base is constructed to provide data support for security work, so as to realize management fusion, data integration and work cooperation. In order to improve the efficiency of security analysis, the present situation of independent security work item management and decentralized security information management is changed. The main contents of this thesis are as follows: firstly, the core business process of civil aircraft safety analysis is dredged, the work items that should be carried out in different stages of development are defined, and the function and performance requirements of the system as a whole are determined. The functions of the system include security task management, security design analysis, security knowledge base management, security data analysis and report, etc., to realize the release of security work task, the execution of design analysis, the inquiry of information, etc. Information monitoring and other functions. Secondly, on the technical level, this civil aircraft security analysis system is a small data analysis and management system based on client / server (B / S) structure, which adopts the mainstream solution of Windows platform. Net Framework4.5. The system adopts the classical three-tier architecture to design the database layer, the business logic layer and the function display layer, and stores and analyzes the data of the enterprise security design and analysis, in order to improve the expansibility, flexibility and maintainability of the whole system. Thirdly, the system adopts the Webservice middleware based on WSDL protocol to realize the data integration with the third party system, and deploys the middleware to the Web server. Each system connects and realizes the data communication based on the HTTP protocol. The data integration of the security analysis system and the existing PDM,P6,OA, reliability design and analysis system is realized, the unified data source analysis is realized, and the cooperation with the research and development is ensured. This paper starts from the actual demand of civil aircraft security analysis system, relies on the theory of security engineering system and the method of software engineering to analyze and design the system, and finally forms the workflow as the main line. The practical security analysis system driven by engineering data has been tested and proved to be feasible at present, but with the increase of actual business demand, the system still needs to be optimized and perfected.
