Maintenance time evaluation method based on degree of health

Abstract

The invention relates to the field of service life management of equipment or parts, and specifically relates to a maintenance time evaluation method based on the degree of health. The invention aims to overcome the defect that inadequate maintenance and excessive maintenance are both caused for the existing maintenance of equipment or parts based on a fixed initial maintenance cycle within the life cycle. In the method of the invention, the current degree of health of equipment or a part is acquired. On one hand, when the current degree of health reaches a warning threshold, the equipment or part is maintained properly according to the actual maintenance demand by means of quality warning. On the other hand, the initial maintenance cycle of the equipment or part can be revised by calibration, and thus, the target maintenance time of the equipment or part determined by a corrected target cycle group is basically in agreement with the target maintenance time determined by quality warning. Therefore, scientific management of the service life of equipment or parts is realized.

Description

technical field [0001] The invention relates to the field of life cycle management of equipment or components, in particular to a health degree-based maintenance time evaluation method. Background technique [0002] At present, the maintenance of equipment or components is usually carried out based on the maintenance cycle. Users can choose to take the initiative to maintain according to a fixed maintenance cycle, or introduce a supervision and early warning mechanism based on the fixed maintenance cycle, such as urging users to maintain the equipment or parts by means of regular reminders. Taking the supervision and early warning mechanism based on a fixed maintenance cycle as an example, although it can increase the service life cycle of equipment or parts to a certain extent, because the aforementioned maintenance cycle is usually set by the equipment manufacturer under the conditions of use (such as It is close to the most normal use environment and the fixed recommende...

Problems solved by technology

However, in this case, the current state of the equipment or parts has often exceeded the limit that can be restored through maintenance, which affects the use of the equipment or parts and related equipment and parts to a certain extent. life cycle

[0004] It can be seen that whether it is based on a fixed maintenance cycle or on the basis of symptoms that require mandatory reminders, the current early warning mechanism has the characteristics of after-the-fact reminders. In most cases, the service life cycle of the equipment or parts has been affected, and to a certain extent, the service life cycle of other equipment or parts related to the device or parts may have been indirectly affected
