AI Technical Summary

Technical Problem

The existing early warning systems for amusement park transmission systems lack in-depth time-frequency analysis of vibration signals from transmission components, making it impossible to effectively identify fault characteristic frequencies. This results in low detection accuracy and a high false negative rate. Furthermore, the lack of a hierarchical early warning mechanism affects equipment safety and operational efficiency.

Method used

By collecting vibration signals from transmission components and performing time-frequency conversion analysis, specific fault characteristic frequencies of real-time rotational speed and structural parameters are identified. By combining the phase and amplitude relationship of vibration signals from multiple measurement points, the fault source is located, and severity levels are classified and warnings are issued based on a hierarchical diagnostic process.

Benefits of technology

It enables precise location and accurate diagnosis of fault characteristic frequencies, improves the accuracy and efficiency of fault detection, and enhances equipment safety and operation and maintenance efficiency.

Abstract

This invention belongs to the field of equipment safety monitoring technology, specifically a method for locating and warning of safety issues in amusement parks. It collects vibration signals from the transmission components of amusement equipment, performs time-frequency conversion analysis, and then, based on the analysis results, identifies specific fault characteristic frequencies determined by real-time rotational speed and transmission component structural parameters. This calibrates the corresponding abnormal state of the transmission component. Next, it receives the abnormal state calibration signal, analyzes the phase and amplitude relationship of vibration signals from multiple measuring points of the transmission component, and, combined with the transmission operation path, locates the vibration fault source of the transmission component. Finally, based on the specific fault characteristic frequencies, it diagnoses the specific cause of the vibration fault source according to a hierarchical diagnostic process, and classifies and warns of corresponding severity levels. This invention can accurately locate the fault source and intelligently identify the specific cause based on a hierarchical diagnostic process, significantly improving the safety and operational efficiency of amusement park equipment.
