Embodiment Construction

[0035] The present invention is described in further detail now in conjunction with accompanying drawing.

[0036] The present invention proposes a kind of electronic form tool realization mode that supports STPA method analysis unsafe control action, comprises the following steps: 1, creates Eclipse RCP project, realizes the platform frame of electronic form tool. Second, use the model-view-controller pattern (MVC) to construct the spreadsheet system. 3. Use the Grid component provided by the Nebula Project in the Eclipse community as the underlying module of our table, and on this basis, analyze the specific requirements of unsafe control actions according to the STPA method, and then perform a layer of encapsulation. Fourth, use the Extensible Markup Language (XML) technology to realize the storage and analysis of table information.

[0037] 1. Create the Eclipse RCP project to realize the platform framework of the spreadsheet tool.

[0038] Eclipse is an integrated devel...

Abstract

The implementation method of the spreadsheet tool for supporting the STPA method to analyze the UCA comprises the following steps that firstly establishing an Eclipse RCP project and achieving a platform framework of the spreadsheet tool; 2, building a spreadsheet system using the model-view-controller model and 3, using a Grid component provided by a Newula Project in an Eclipse community as a bottom layer module of the table, analyzing a specific demand of an unsafe control action according to an STPA method on the basis, and carrying out layer-by-layer packaging. and 4, storing and analyzing the table information by using an extended markup language technology. Compared with the prior art, the method has high portability and platform independence, editing of unsafe control actions can be achieved, the unsafe control actions can be connected with harm, safety analysis personnel can conduct safety analysis work more clearly, and storage and analysis of analysis results are facilitated.

Description

technical field [0001] The invention belongs to the technical field of security analysis of complex systems, and in particular relates to an implementation method of an electronic form tool supporting STPA method analysis UCA. Background technique [0002] Systems-Theoretic Accident Model and Processes (STAMP) was proposed by Nancy G.Leveson of MIT in 2004. STAMP is a new accident causality model based on system theory and extended on the traditional accident model. The traditional event chain-based failure model regards component failure as the cause of the accident, while the STAMP model regards the system as a whole, and the security of the system is determined by the interaction between the various components in the system. [0003] Based on the STAMP accident model, Leveson proposed a specific hazard analysis method - System-Theoretic Process Analysis (STPA). STAMP emphasizes that hazards are caused by unsafe control behaviors, while STPA focuses on how to find out th...
