Embodiment 1

[0056] like figure 1 As shown, the present embodiment provides a fault tree analysis-based logic control sensitive component identification system, including:

[0057] Reading equipment normal data information module 1, which reads equipment data information; reading equipment normal data information includes equipment basic information data, equipment function maintenance data, and equipment parts list data. Reading more device data information can better determine fault data.

[0058] Read the equipment failure mode data information module 2, which reads the equipment failure mode data information; the equipment failure mode data information includes the possible failure mode data of the equipment function and the failure mode data of each component. Read all possible fault module data to make the final drawn fault tree graph more accurate.

[0059] Data analysis and identification module 3, in this module, each piece of failure mode data information is analyzed and identi...

Embodiment 2

[0072] like figure 2 As shown, a method for identifying sensitive components of logic control based on fault tree analysis provided by this embodiment includes the following steps:

[0073] S1: the step of reading the normal data information of the device; the reading of the normal data information of the device includes the basic information data of the device, the function maintenance data of the device, and the parts list data of the device. Reading more device data information can better determine fault data.

[0074] S2: The step of reading the failure mode data information of the device; the failure mode data information of the device includes the possible failure mode data of the device function and the failure mode data of each component. Read all possible fault module data to make the final drawn fault tree graph more accurate.

[0075] S3: Analyze and identify each piece of failure mode data information, and then mark key sensitive functional information;

Abstract

The invention relates to a logic control sensitive component identification system and method based on fault tree analysis. The system includes: a reading device normal data information module, in which the data information of the device is read; the device failure mode data information is read. module, which reads the failure mode data information of the equipment; data analysis and identification module, in this module, analyzes and identifies each failure mode data information, and then marks the key sensitive function information; top event determination module, this module , select the fault mode of one of the sensitive functions as the top event, and enter the corresponding description data information; the fault tree graphic drawing module, in this module, the fault tree graphic is drawn in the drawing area, and each event selects the fault corresponding to the component model.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a logic control sensitive component identification system and method based on fault tree analysis. Background technique [0002] Key sensitive equipment refers to equipment that can cause power plant shutdown, shutdown, power reduction, and large power fluctuations due to a single equipment failure. The sensitive components of key sensitive equipment are usually identified and managed in power plants. The identification of sensitive components in the logic control system involved in the equipment is usually analyzed using the fault tree analysis method. The analysis process will use auxiliary drawing software or online drawing websites to draw the equipment functional fault tree. Common auxiliary drawing software or online drawing websites include Microsoft Visio, Edraw, ProcessOn, etc. [0003] In the process of identifying sensitive parts, use the existing auxiliary drawin...
