Equipment fault early warning method based on maintenance records

Abstract

The invention discloses an equipment fault early warning method based on maintenance records. The equipment fault early warning method based on the maintenance records comprises the following steps ofstep 1.acquiring a maintenance record table; step 2.counting the total number of all equipment with the type l in a room k; step 3.repeating the steps 4 and 5 for all fault types possibly occurring in the equipment with the type l in the room k; step 4.counting maintenance frequency of each equipment i with the type l in the room k in a certain time period due to a fault j; step 5.counting maintenance frequency of equipment d needing detection and early warning in a certain time period due to the fault j; step 6.setting an influence factor and an early warning threshold value; step 7.settingan early warning threshold value corresponding to the equipment type l in the room k; step 8.computing values of early warning indexes I1 and I2; step 9.if I1 is not less than 0, triggering the same fault early warning of the same type of equipment; if I2 is not less than 0, triggering repeated fault early warning of the same equipment; and step10.resetting final triggering early warning time.

Description

technical field [0001] The invention relates to the field of early warning of equipment failure, in particular to a method for early warning of equipment failure based on maintenance records. Background technique [0002] At present, the number and types of equipment owned by many units are increasing day by day, and the difficulty of management and maintenance of equipment is also increasing. According to data, a general-sized comprehensive university has thousands of computers, in addition to projectors, switches, routers, air conditioners and other equipment. The huge number of equipment greatly increases the probability of various sudden failures. Equipment administrators often need to deal with various sudden equipment failures at any time to ensure the normal operation of the unit's daily work. [0003] Regular inspection and maintenance of equipment is a traditional means to ensure the normal work. But carry out regular manual maintenance to a large amount of equipm...

AI Technical Summary

Problems solved by technology

But carry out regular manual maintenance to a large amount of equipment, there are following problems: 1, expend more manpower

The administrator needs to test and diagnose each component of each device, and repair the faulty components one by one, which is extremely heavy workload

2. It is easy to miss the situation

There are certain subjective factors in manual maintenance and diagnosis, and the potential failures of some equipment may not be discovered in time by manual maintenance.

3. Indiscriminate unified maintenance lacks scientificity

There are large differences in the types and probabilities of failures of different components of different equipment types, and undifferentiated maintenance lacks pertinence and scientificity, which will also cause waste of manpower

In equipment management, due to equipment quality, use environment, maintenance methods, etc., failures of similar equipment in the same room are usually related, and there is a greater possibility of recurrence after the failure of the same equipment
