Motor bearing replacement request analysis system

Abstract

The invention relates to a motor bearing replacement request analysis system, and the system comprises an interval extraction device which is used for taking the entity distance with the maximum numerical value in each part of entity distance corresponding to each first pixel point and second pixel point combination as the farthest interval distance of a bearing outer ring and a bearing inner ring for output; and the request triggering equipment is used for wirelessly sending a bearing replacement request to a far-end cloud computing server when the received farthest spacing distance between the bearing outer ring and the bearing inner ring is greater than or equal to a set distance limit. The motor bearing replacement request analysis system is compact in structure and stable in operation. The longest spacing distance between the bearing outer ring and the bearing inner ring can be identified by adopting a targeted visual analysis mechanism, and when the longest spacing distance is greater than or equal to the set distance limit, the bearing replacement request is wirelessly sent to the cloud computing server at the far end; therefore, equipment replacement processing which influences normal working performance based on the fact that the farthest distance between the inner ring and the outer ring of the motor bearing is too large is completed.

Description

Technical Field

[0001] The present invention relates to the field of AC motors, and more specifically, to a motor bearing replacement request parsing system. Background Art

[0002] AC motors generally use three-phase system, because three-phase AC motors have obvious advantages over single-phase motors in terms of performance indicators, raw material utilization and price. Three-phase motors of the same power are smaller in size, lighter in weight and cheaper in price than single-phase motors. Three-phase motors have self-starting capabilities. Single-phase motors have no starting torque, so some special measures need to be taken to solve the starting problem. The torque of single-phase motors is pulsating and the noise is relatively large, but the power supply required is relatively simple, which is very convenient to use in the home. Therefore, small household motors and instrument motors mostly use single-phase motors.

[0003] When the maximum distance between the inner and outer rings of the AC motor bearing is too large, it will affect the normal working performance of the AC motor, and the corresponding equipment replacement request will be triggered. However, the existing technology lacks a high-precision and targeted detection mechanism for the maximum distance between the inner and outer rings of the AC motor bearing, making it difficult to capture the timing of equipment replacement.

[0004] There is no corresponding solution disclosed in the prior art. Summary of the invention

[0005] The present invention provides a motor bearing replacement request parsing system, which uses each constituent pixel point of a first image block as each first pixel point, and each constituent pixel point of a second image block as each second pixel point, to obtain the number of interval pixels between two pixels in any first pixel point second pixel point combination to determine the physical distance corresponding to any first pixel point second pixel point combination, and uses the physical distance with the largest value among the physical distances corresponding to each first pixel point second pixel point combination as the longest interval distance between the outer ring of the bearing and the inner ring of the bearing, and also references a request triggering device for wirelessly connecting to a remote cloud computing server, and is used to wirelessly send a bearing replacement request including the farthest interval distance between the outer ring of the bearing and the inner ring of the bearing and the corresponding motor number of the AC motor to the remote cloud computing server when the received farthest interval distance between the outer ring of the bearing and the inner ring of the bearing is greater than or equal to a set distance limit, thereby completing the equipment replacement processing based on the farthest distance between the inner ring and the outer ring of the motor bearing affecting the normal working performance, thereby solving the technical problems in the related field.
