Embodiment Construction
[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0027] The results presented by the motor fault diagnosis system not only include a diagnosis of the motor itself, but also a comprehensive evaluation of the entire system including power supply, control devices and motors; It comes from the motor itself, and more than 60% of the faults come from the devices on the power supply path, that is, the power failure of the motor. As a long-term online diagnosis of the motor fault diagnosis system, first of...

The invention provides a method for representing a motor fault diagnosis result, and aims to solve the problem that a traditional motor fault detection result is presented in a total score or distribution score evaluation mode, and multiple pieces of time and space feature information of different dimensions cannot be obtained. On the basis of analyzing the common fault condition of a field motor, the invention provides a laminated motor fault diagnosis result representation mode. The laminated motor fault diagnosis result representation mode goes deep in a laminated mode in the form of language by using a deep learning concept, and different feature information is learned in different depth processes. A result presented by a motor fault diagnosis system not only comprises a diagnosis for the motor, but also is a comprehensive evaluation for an integral system comprising a power supply, a control device and the motor.
Description
technical field [0001] The patent of the present invention relates to the field of motor detection and diagnosis, in particular to a method for displaying motor fault diagnosis results. Background technique [0002] The emergence of the motor fault diagnosis system provides a certain guarantee for the safe and reliable operation of the motor, and the results provide maintenance and maintenance guidance for users and inspectors. Therefore, for the end-effector motor in operation, the presentation method of the results is The interface for human-computer interaction, its presentation effect can effectively improve personnel's understanding of motor faults and efficiently solve the problem of motor faults during operation. The traditional way of presenting the results is through the total score or distribution score evaluation. It is expressed in a digital form, and what it expresses is a mathematical language. The distribution score is generally an overall score for a certain ...
