Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, and in particular to an abnormality monitoring device and method for electric power equipment based on voiceprint recognition. Background Art

[0002] The power equipment abnormality monitoring device based on voiceprint recognition is a system that uses acoustic principles and artificial intelligence technology to monitor and analyze the operating status of power equipment. The sensors in the device can capture the sounds generated when the equipment is running. These sound signals may include the normal operating sound of the equipment, abnormal noise or vibration. Through a preset algorithm, the system extracts voiceprint features from the collected sound signals. These features are similar to human fingerprints. The voiceprint features of each device are unique and closely related to its operating status. Then, deep learning technology is used to analyze the voiceprint features. The trained model can identify subtle changes in the voiceprint, which may indicate equipment abnormalities or failures.

[0003] A Chinese patent with publication number CN218729891U discloses a power equipment fault judgment device based on voiceprint recognition technology, including a hanging track, a moving mechanism, a voiceprint recognition terminal, a lifting mechanism, a pan-tilt head and a voiceprint sensor. The utility model uses a voiceprint sensor to collect sound information of power equipment. The voiceprint sensor can be moved and can monitor multiple power equipment.

[0004] The above-mentioned and similar existing technologies can monitor power equipment to a certain extent. However, when the existing monitoring device is working, the sounds emitted by multiple power equipment are intertwined and mixed during the process of propagation in the air, so that the soundprint finally received by the monitoring device is a mixed soundprint, which means that after the monitoring device detects the abnormal sound, it can determine the general direction of the abnormal sound, but it is difficult to distinguish the specific location of the power equipment that emits the abnormal sound, which reduces the accuracy of the monitoring equipment. In addition, most of the existing monitoring equipment uses sound and light warnings after detecting the abnormality, which only has a warning effect, increases the work content of subsequent staff to determine the location of the abnormal equipment, and reduces work efficiency.

[0005] Therefore, the present invention provides an abnormal monitoring device and method for electric power equipment based on voiceprint recognition, which can capture abnormal sounds in a 360° three-dimensional space around it and use lights to point out the location of abnormal equipment to staff.

[0043] A monitoring method for abnormal monitoring equipment of power equipment based on voiceprint recognition:

[0044] S1. When the voiceprint monitor 15 detects an abnormal sound, the telescopic rod 14 is started to extend to drive the voiceprint monitor 15 to move downward. The telescopic rod 14 drives the voiceprint monitor 15 to rotate and move downward through the cooperation of the driving mechanism 2 and the rotating mechanism 3, so that the voiceprint monitor 15 can cover the surrounding 360° three-dimensional space and capture the specific location of the power equipment that emits the abnormal sound;

[0045] S2, when the telescopic rod 14 extends to drive the sliding plate 23 to move, the sliding plate 23 drives the protrusion 413 to contact the switch 412 to start the strip light 44, so that the light of the strip light 44 forms a light curtain, and at the same time the arc tooth plate 45 slides to expose the strip light 44;

[0046] S3, after the telescopic rod 14 is extended to the limit, the specific position of the power equipment that makes the abnormal sound has been determined, and the output end of the telescopic rod 14 is recovered for reset. During the reset process, the rotating mechanism 3 drives the strip light 44 to rotate, so that the light curtain formed by the strip light 44 rotates and moves, and the light curtain is aimed at the power equipment that makes the abnormal sound;

[0047] S4, the telescopic rod 14 continues to reset, and drives the strip light 44 to rotate an integer multiple, and during the reset process, the arc tooth plate 45 is also reset, so that the arc tooth plate 45 gradually covers the strip light 44, and the light curtain gradually shrinks. When the edge of the light curtain approaches the power equipment that makes abnormal sounds, it stops moving.

[0048] Working principle: The staff first fixes the mounting plate 11 on the top of the room with bolts, and then powers on the device, so that the voiceprint monitor 15 monitors the power equipment in the room. When the power equipment makes an abnormal sound, the telescopic rod 14 extends to drive the voiceprint monitor 15 at the output end to move downward. At the same time, the telescopic rod 14 drives one end of the rotating plate 22 to move downward through the side rods 21 on both sides, so that the other end of the rotating plate 22 moves toward the direction of the telescopic rod 14 under the action of external force, and the rotating plate 22 drives the sliding plate 23 to move, so that the sliding plate 23 moves under the limiting action of the limiting plate 28 and the sliding hole 13. The sliding plate 23 drives the spur plate 27 to move, so that the spur plate 27 drives the thin rod 32 to rotate by meshing with the small gear 33, so that the thin rod 32 drives the large gear 34 to rotate, and the large gear 34 rotates and meshes with the fixed gear ring 36. Under the reaction force of the meshing, the large gear 34 drives the rotating box 31, the top plate 12 and all the components at the bottom thereof to rotate with the fixed rod 35 as the center, so that the voiceprint monitor 15 moves downward and rotates at the same time, and captures the abnormal sound in the surrounding 360° three-dimensional space, so as to determine the specific location of the power equipment that emits the abnormal sound;

[0049] When the telescopic rod 14 is extended and drives the sliding plate 23 to move, the sliding plate 23 drives the protrusion 413 to contact the switch 412 to start the strip light 44. At the same time, the sliding plate 23 moves through the meshing action of the tooth groove 26 and the transmission tooth 410 to drive the rotating shaft 49 to rotate. The rotating shaft 49 drives the rotating rod 47 to rotate through the transmission action of the two sets of pulley groups 411, so that the rotating rod 47 drives the central tooth 48 to rotate. The central tooth 48 rotates and drives the arc tooth plate 45 to slide along the inner side of the slide groove 43 through the meshing action with the arc tooth plate 45, so that the arc tooth plate 45 slides in the direction of the telescopic rod 14, and the arc tooth plate 45 is moved away from the surface of the strip light 44, so that the light of the strip light 44 is irradiated to form a light curtain, and the light curtain passes through the abnormal equipment to determine the position and direction of the abnormal equipment;

[0050] When the telescopic rod 14 is extended to the limit, the specific position of the power equipment that emits the abnormal sound has been determined, and then the output end of the telescopic rod 14 is recovered for reset. During the reset process, the top plate 12 is driven to rotate again, so that the top plate 12 drives the right-angle block 41 to rotate, and the strip light 44 inside the right-angle block 41 is rotated, so that the light curtain formed by the strip light 44 rotates and moves. After the light curtain is aligned with the power equipment that emits the abnormal sound, the telescopic rod 14 continues to reset and drives the strip light 44 to rotate by an integer multiple of the number of circles. During the reset process, the arc tooth plate 45 is also driven to slide and reset, so that the arc tooth plate 45 gradually covers the surface of the strip light 44, and the light curtain gradually shrinks. When the edge of the light curtain approaches the power equipment that emits the abnormal sound, it stops moving;

[0051] When the electrical equipment no longer makes abnormal sounds, the telescopic rod 14 continues to reset, and the protrusion 413 contacts the switch 412 again to turn off the strip light 44, and the arc tooth plate 45 completely covers the strip light 44, so that the entire device is reset to the initial state.
