Description

An error-proofing method and system for a visual tool for maintenance of rail transit parts and components

technical field

The invention belongs to the field of rail transit component overhaul error prevention, and in particular relates to a rail transit component overhaul visualization tool error prevention method and system.

Background technique

Error proofing is the design and development of products and manufacturing processes to prevent possible errors in production and to prevent the manufacture of substandard products. With the continuous improvement of people's requirements for production efficiency, the frequency of use of production tools is getting higher and higher, and the error-proofing requirements for the use and management of tools in the production process are becoming more and more urgent.

The maintenance of locomotive parts is an important part of the locomotive maintenance process, which is directly related to the smooth operation of the locomotive. Tool error proofing is an important part of the maintenance process of parts and components, which has a direct impact on the maintenance quality and maintenance efficiency.

Most of the existing error-proofing methods for tools in the operation process are divided into two types. One is to number each tool, and to select and use the tool number required by querying the manual in the specific process.

The other is to design a tool error-proofing disk or error-proofing box, and match the tools to the fixed positions on the error-proofing disk or error-proofing box to ensure the correct use of the tool.

However, the former method does not regulate the placement position of the tools, so that the tools may be randomly placed or lost, which affects the maintenance efficiency. When there are too many tools or maintenance steps, the latter method may also have the problem of getting the wrong tool or finding the tool for too long. Therefore, there is an urgent need for a comprehensive error-proofing solution for parts maintenance tools, which can reduce the losses caused by improper use of tools during the maintenance process.
