Auxiliary equipment maintenance system and method

Abstract

The invention discloses an auxiliary equipment maintenance system and method, and the system comprises an emergency maintenance management module, a maintenance personnel management module, a fault preprocessing module, a spare part online management module, and a maintenance process analysis and evaluation module. The method comprises the following steps of emergency maintenance management, maintenance personnel management, fault preprocessing, spare part online management, maintenance process analysis and evaluation and the like, accurate matching of faults and maintenance personnel is achieved through a fault preprocessing module, and effective utilization rate of maintenance personnel is improved. Through the fault preprocessing module, possible fault causes are predicted through the fault tree structure, the fault maintenance time is shortened, and the maintenance efficiency is improved. The fault tree model in the fault preprocessing module is upgraded and perfected through the maintenance process analysis and evaluation module, and the accuracy of fault reason judgment of the fault preprocessing module is continuously improved.

Description

technical field [0001] The invention relates to the technical field of workshop intelligent management, in particular to a system and method for auxiliary equipment maintenance. Background technique [0002] At present, the application proportion of automation and intelligent equipment in the workshop of my country's manufacturing industry is getting higher and higher, and the breakdown of equipment failure is getting higher and higher. It is very important for maintenance personnel to repair these equipment in time. There is no relatively scientific and systematic means to help maintenance personnel analyze faults, and information technology is not used to rationally allocate maintenance personnel for different subdivided faults to improve maintenance efficiency. The downtime and maintenance progress only rely on maintenance personnel Individual skill level, unable to predict downtime, helps management to make production decisions. The existing traditional maintenance method...

[0002] At present, the application proportion of automation and intelligent equipment in the workshop of my country's manufacturing industry is getting higher and higher, and the breakdown of equipment failure is getting higher and higher. It is very important for maintenance personnel to repair these equipment in time. There is no relatively scientific and systematic means to help maintenance personnel analyze faults, and information technology is not used to rationally allocate maintenance personnel for different subdivided faults to improve maintenance efficiency. The downtime and maintenance progress only rely on maintenance personnel Individual skill level, unable to make predictions about downtime, helping management to make production decisions

The existing traditional maintenance methods such as paper repair forms and experience maintenance have the following three defects: (1) After a failure occurs on site, relying on paper repair forms cannot further refine the subdivision time period in the maintenance process, so that continuous maintenance Targeted improvement, management personnel can not obtain the maintenance progress at the current moment

(2) After the maintenance personnel arrive at the scene, they only rely on experience to analyze the cause of the failure, lacking the assistance of information technology, and it takes a long time to determine the cause of the failure

(3) The existing spare parts warehouse system is often an independent system, and the spare parts information cannot be obtained during the maintenance process. There is often a waste of time in the spare parts requisition during the maintenance process, so people need a system and method for auxiliary equipment maintenance. solve the above problems
