Abstract

The invention provides a multi-way valve failure data management and failure mode automatic diagnosis system. The multi-way valve failure data management and failure mode automatic diagnosis system comprises a user information login management module, a failure case information management module, a failure information query module, a part information management module, a failure mode automatic diagnosis module and a failure case rule base module. According to the invention, previous scattered multi-way valve failure case data are combined and classified through advanced network and database technologies, the data are stored in the database in a certain mode, rules can be summarized and found in numerous failure cases, and the possibility of faults is pre-judged on the basis of the rules; an engineer can have references when dealing with the failure of the multi-way valve, the fault case analysis process is simplified, the fault analysis and processing efficiency is improved, the working time is shortened, unnecessary waste and repeated work are avoided, and faults can be prevented in advance.

Description

technical field [0001] The invention relates to the technical field of data management, in particular to a multi-way valve failure data management and failure mode automatic diagnosis system. Background technique [0002] With the continuous development of the construction industry and frequent accidents of construction machinery and equipment, and due to the harsh working environment of construction machinery, frequent reversing of the hydraulic system, and drastic load changes, the possibility of multi-way valve failure is also increasing. Therefore, the safety and reliability of multi-way valves have gradually become the focus of attention. The technical status of the multi-way valve will change with the use and the failure of internal parts. When the parts are damaged and lose the functions of the original design, the engineer will carry out troubleshooting, failure analysis and propose improvement measures to prevent similar valves in the future. recurrence of the acci...
