Description

Intelligent gap-adjusting magnetic non-contact flywheel transmission response supervision method and system Technical Field The invention relates to the technical field of flywheel transmission, in particular to an intelligent gap-adjusting magnetic non-contact flywheel transmission response supervision method and system. Background In the technical field of flywheel transmission, particularly in the fields of flywheel power generation, industrial mechanical transmission and the like, the magnetic non-contact transmission is widely applied due to the advantages of no mechanical abrasion, low noise, adaptation to severe working conditions and the like, and the intelligent gap adjustment in the flywheel power generation field is a technology for accurately identifying the dynamic deviation state of a transmission gap by collecting key magnetic transmission parameters such as magnetic strength, transmission torque, rotation speed difference and the like in real time and combining the parameter change rule of time dimension in a magnetic non-contact flywheel transmission system, and automatically adjusting the rotation speed of the flywheel by an intelligent adjusting and controlling device so as to ensure that the transmission gap is always maintained in a preset reasonable range (the magnetic interference or mechanical abrasion caused by the reduction of transmission efficiency and the undersize caused by overlarge transmission efficiency is avoided). The method has the core that manual intervention is not needed, shutdown detection is not relied on, real-time, quantitative and dynamic regulation and control of gap adjustment are realized, scenes such as speed fluctuation and working condition change in flywheel power generation are adapted, and high precision and high stability of a transmission system are ensured. However, the existing gap adjusting technology of magnetic non-contact flywheel transmission still has a plurality of problems to be solved urgently, and the transmission efficiency and the operation stability are severely restricted. In the flywheel transmission process, the transmission clearance is easy to generate dynamic change due to the influence of factors such as rotation speed fluctuation, temperature change, magnetic force attenuation and the like, the instantaneous abnormality is difficult to capture by manual adjustment, the production efficiency is reduced due to shutdown operation, and particularly, the energy loss can be caused by shutdown clearance adjustment in continuous operation scenes such as flywheel power stations and the like. In magnetic non-contact transmission, gap-adjusting abnormality is closely related to parameter fluctuation of a specific time node, and the traditional technology lacks a time stamp marking and sample cluster construction mechanism, so that an abnormality cause is difficult to locate, a gap-adjusting change trend cannot be prejudged, and faults can only be passively responded. In the prior art, an error calculation model based on parameter threshold values is not established, and the degree of deviation of the clearance adjustment from a normal state cannot be accurately represented, so that the subjectivity of a speed adjustment decision is strong, excessive adjustment or insufficient adjustment is easy to occur, the transmission precision is further affected, and even the equipment loss is aggravated. The problems cause the defects of low gap adjusting precision, poor operation efficiency, high maintenance cost, high fault risk and the like of the existing magnetic non-contact flywheel transmission system, and the requirements of high precision, intellectualization and continuous operation of the transmission system for modern industrial production and new energy power generation are difficult to meet.
