Description

Technical Field

[0001] This utility model relates to the field of audio fusion anomaly monitoring technology, specifically to an anomaly monitoring and warning device for multi-channel audio fusion. Background Technology

[0002] Multi-channel audio fusion anomaly monitoring technology integrates multi-source audio signals and combines signal processing and machine learning algorithms to significantly improve the ability to detect abnormal events in complex scenarios. This technology simultaneously collects equipment vibration sounds (low frequency 20-200Hz), gear meshing sounds (high frequency 1-10kHz), and environmental noise. By fusing time-frequency features, it distinguishes between normal wear and tear and fault impacts, thereby enabling fault detection in mechanical equipment.

[0003] Existing audio fusion-based anomaly monitoring and warning devices are not conducive to tightly fitting multi-channel sound sensors to the inner wall of the gearbox, and cannot provide adequate buffering protection, resulting in low accuracy in monitoring mechanical equipment anomalies. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a multi-channel audio fusion anomaly monitoring and warning device. The audio fusion anomaly monitoring and warning device allows the multi-channel sound sensor to fit tightly against the inner wall of the gearbox and has a certain degree of buffer protection, which greatly improves the accuracy of anomaly monitoring of mechanical equipment.

[0005] The technical solution adopted by this utility model to solve its technical problem is a multi-channel audio fusion abnormal monitoring and warning device, including a vertical rod, a sleeve rod and a mounting base. The top of the mounting base is welded with a vertical rod and a clamp is sleeved on the vertical rod. A U-shaped clamping plate is welded to one side of the clamp and an alarm is installed on the top of the U-shaped clamping plate by bolts. An audio processor is sleeved inside the U-shaped clamping plate.

[0006] The top of the vertical rod is held by a rod clamping block to hold a sleeve rod. An inner telescopic rod is sleeved inside the sleeve rod, and a connecting plate is welded to one end of the inner telescopic rod. An L-shaped fixing plate is connected to one side of the connecting plate by a support spring, and a multi-channel sound sensor is installed in the L-shaped fixing plate by screws.

[0007] By adopting the above technical solution, the audio fusion anomaly monitoring and warning device makes the multi-channel sound sensor fit tightly against the inner wall of the gearbox and has a certain buffer protection, which greatly improves the accuracy of anomaly monitoring of mechanical equipment.

[0008] Specifically, a locking bolt is installed on one side of the U-shaped clamping plate through a screw hole, and one end of the locking bolt is connected to a rubber pressure plate through a connecting bearing. The audio processor is pressed and fixed by the rubber pressure plate.

[0009] Specifically, mounting bolts are evenly spaced on the mounting base, and an adjusting screw is installed on one side of the top end of the sleeve through a screw hole.

[0010] By adopting the above technical solution, the mounting bolts on the mounting base facilitate the installation of the entire device on one side of the gearbox of the mechanical equipment, and the positioning of the inner telescopic rod is achieved by tightening the adjusting screw.

[0011] Specifically, both ends of the support spring are connected to the connecting plate and the L-shaped fixing plate respectively through positioning plates and positioning screws.

[0012] Specifically, the output and input terminals of the audio processor are electrically connected to the input terminal of the alarm and the output terminal of the multi-channel sound sensor via wires.

[0013] By adopting the above technical solution, multi-channel sound sensors are used to simultaneously collect equipment vibration sounds, gear meshing sounds, and environmental noise. The audio processor uses time-frequency characteristic fusion to distinguish between normal wear and abnormality. When an abnormality occurs, the alarm will be automatically activated.

[0014] The beneficial effects of this utility model are:

[0015] (1) The multi-channel audio fusion abnormal monitoring and warning device described in this utility model uses the mounting bolts on the mounting base to facilitate the installation of the whole device on one side of the gearbox of the mechanical equipment. Loosening the adjusting screw facilitates the adjustment of the exposed length of the inner telescopic rod, thereby attaching one end of the multi-channel sound sensor to one side of the gearbox. Tightening the adjusting screw realizes the positioning of the inner telescopic rod. Furthermore, the elastic force of the support spring is used to make the multi-channel sound sensor fit tightly against the inner wall of the gearbox, and it also has a certain buffer protection.

[0016] (2) The multi-channel audio fusion abnormal monitoring and warning device described in this utility model uses multi-channel sound sensors to simultaneously collect equipment vibration sound, gear meshing sound and environmental noise. It distinguishes normal wear and abnormality by fusing the time and frequency characteristics of the audio processor. When an abnormality occurs, it will automatically control the alarm to sound an alarm, reminding maintenance personnel to carry out timely maintenance, which greatly improves the accuracy of abnormal monitoring of mechanical equipment.
