Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0029] refer to Figure 1-7 , a kind of fault tree analysis method of S700K turnout switch machine, comprises the following steps:

[0030] S1, forming a fault description through fault mode impact fault analysis;

[0031] S2. Combining the fault description formed in S1 with the fault history database of the system to form a fault diagnosis process database, the fault diagnosis process database at least includes fault manifestations and fault traceability;

[0032] S3, Fault tree analysis is performed on the basis of the fault diagnosis process database, thereby supplementing the cause of multi-point faults that lead to the failure of the switch machine. In this st...

Abstract

The invention discloses a fault tree analysis method for an S700K turnout switch machine. The method comprises the following steps: S1, influencing fault analysis through a fault mode to form a fault description; S2, combining the fault description formed in the step S1 with a fault historical database of the system to form a fault diagnosis process database, wherein the fault diagnosis process database at least comprises fault performance and fault traceability; s3, carrying out fault tree analysis on the basis of the fault diagnosis process database, so that multi-point fault reasons causing faults of the turnout switch machine are supplemented; and S4, converting the fault tree into a fault analysis positioning tree, and positioning and analyzing the fault of the turnout switch machine through the fault analysis positioning tree. According to the method, the turnout fault of the switch machine of a specific switch machine type can be quickly obtained, the analysis efficiency is high, the judgment accuracy is high, and each machine type adopts a specific fault tree.

Description

technical field [0001] The invention relates to the technical field of switch machines, in particular to a fault tree analysis method for S700K switch machines. Background technique [0002] The switch machine comprehensive monitoring and acquisition sub-unit is responsible for collecting the display gap value of the switch machine, the operation video and the gap shaking amount, the passing car video and the gap shaking amount, the temperature and humidity in the switch machine box, the vibration acceleration and other parameters, and upload the measurement results to the indoor monitoring station for data analysis, data display and over-limit alarm to realize human-computer interaction. The overall structure of the system adopts CS structure. The monitoring software is divided into client and server. The client is mainly responsible for the data collected by the switch machine. The storage, display, and alarm and interaction functions related to the operator. The fault tre...
