Embodiment Construction

[0015] Please refer to figure 1 The dynamic preventive maintenance method for electromechanical equipment includes fault prediction, such as step 1; fault diagnosis, such as step 2; dynamic generation of preventive maintenance methods, such as step 3; preventive maintenance performance evaluation and result feedback, such as step 4.

[0016] Fault prediction, as in step 1. The fault prediction method is selected to predict the possible fault time and fault type of electromechanical equipment.

[0017] Fault prediction mainly includes: (1) Predicting the time of failure of electromechanical equipment, where the time can be a small interval and does not require a specific time. (2) Predict the types of mechanical and electrical equipment failures. Because different electromechanical equipment has different fault distribution rules in its entire life cycle, it is necessary to analyze the historical fault records of electromechanical equipment first to obtain the possible fault ...

Abstract

The invention discloses a dynamic preventative maintenance method for electromechanical equipment. The method comprises the following steps of: forecasting a fault; diagnosing a fault; dynamically generating the preventative maintenance method; and estimating preventative maintenance performance and feeding a result. In the method, contents such as the preventative maintenance content, the preventative maintenance mode, the fault damage degree level, the preventative maintenance allowance region and the like of each type of fault mode in each stage of a full life span of the electromechanicalequipment are taken into consideration fully; therefore, a preventative maintenance task sheet can be dynamically generated by aiming at different preventative maintenance targets; and the preventative maintenance task sheet is adjusted according to a feedback result of the preventative maintenance performance estimation.

Description

technical field [0001] The invention relates to preventive maintenance management of electromechanical equipment, in particular to a method for dynamically providing preventive maintenance strategies and maintenance opportunities in combination with information from three aspects: fault prediction, fault diagnosis, and preventive maintenance performance evaluation. Background technique [0002] The preventive maintenance of equipment refers to the maintenance carried out according to the predetermined plan or target in order to maintain the specified function of the system and prevent the degradation of system performance, and it is usually called prior maintenance. [0003] Although preventive maintenance has various benefits such as reducing unplanned equipment downtime and prolonging equipment life, unreasonable preventive maintenance methods may result in excessive redundancy or insufficient maintenance. When maintenance is excessive, frequent repairs will cause equipmen...
