Description

Technical Field

[0001] This utility model relates to the field of voiceprint video surveillance technology, and in particular to a video surveillance device based on voiceprint recognition. Background Technology

[0002] Voiceprint recognition, a type of biometric technology, also known as speaker recognition, includes speaker identification and speaker verification. Voiceprint recognition converts sound signals into electrical signals, which are then identified by a computer. Different tasks and applications will use different voiceprint recognition technologies.

[0003] In the existing technology, when using voiceprint recognition video surveillance devices, the camera orientation is fixed after installation, making it impossible for the device to rotate according to the direction of the voiceprint. Secondly, because the angle of the voiceprint recognition video surveillance device is fixed after installation, it is not convenient to adjust and track in real time according to the voiceprint. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a video surveillance device based on voiceprint recognition, comprising: a fixed plate, a rotating device provided at the bottom of the fixed plate, four connecting columns equidistantly mounted around the bottom of the fixed plate, a fixed plate mounted at the bottom of the four connecting columns, a fixing hole provided at the center of the bottom of the fixed plate, a connecting plate mounted at the bottom of the rotating device, and an angle adjustment device mounted in the middle of the bottom of the connecting plate.

[0006] In a preferred embodiment, the rotating device includes four rotating shafts, one of which is equipped with a first forward and reverse motor at its top. Transmission gears are fixedly fitted on the bottom of the surfaces of the four rotating shafts, and double-belt grooved pulleys are fixedly fitted on the top of the surfaces of the four rotating shafts. Three transmission belts are interleaved and movably embedded inside the four double-belt grooved pulleys. Rotating gears are meshed with the surfaces of the four transmission gears, and a rotating shaft is fixedly inserted through the center of the surface of the rotating gear.

[0007] In a preferred embodiment, one end of one of the three rotating shafts is mounted on the bottom of the fixed plate by bearings, the other end of the three rotating shafts is mounted on the top of the fixed disk by bearings, and one end of the surface of the other rotating shaft extends movably through the surface of the fixed disk.

[0008] In a preferred embodiment, the other end of the other rotating shaft is mounted on the bottom of the fixed plate via a bearing, one end of the first forward and reverse motor is mounted on the bottom of the fixed plate, the top end of the rotating shaft is mounted on the center of the bottom of the fixed plate via a bearing, and the surface of the rotating shaft is movably embedded inside the fixed hole.

[0009] In a preferred embodiment, the angle adjustment device includes a second forward and reverse motor. The output end of the second forward and reverse motor is fixedly connected to a drive shaft. A rotating gear is fixedly sleeved on the surface of the drive shaft. A connecting gear is meshed on the surface of the rotating gear. A fixed shaft is fixedly inserted through the center of the surface of the connecting gear. An extension plate is installed on one side of the connecting gear. A camera is installed at the center of one end of the extension plate. Four voiceprint sensors are installed around the camera at one end of the extension plate.

[0010] In a preferred embodiment, one end of the second forward and reverse motor is mounted on one side of the U-shaped support plate, and one end of the drive shaft surface movably extends through the surface of the U-shaped support plate.

[0011] In a preferred embodiment, the other end of the drive shaft is mounted on one side inside the U-shaped support plate via a bearing, and both ends of the fixed shaft are mounted on both sides inside the U-shaped support plate via bearings.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the voiceprint sensor collects and monitors sound wave information in real time and transmits it back to an external control terminal. The control terminal analyzes and processes the sound source direction information transmitted back by the voiceprint sensor, and starts the first forward and reverse motor. The first forward and reverse motor drives the rotating shaft to rotate, which in turn drives the transmission gear to rotate. The rotation of the transmission gear drives the extension plate and the rotating shaft to rotate, which transmits the power to the connecting plate and the U-shaped support plate, thereby adjusting the orientation of the camera. This avoids the phenomenon that some monitoring devices have a fixed camera orientation after installation, which prevents the device from rotating according to the direction of the voiceprint.

[0014] 2. In this utility model, when adjusting the camera angle, the external controller starts the second forward and reverse motor to drive the transmission shaft and rotating gear to rotate according to the direction of the voiceprint determined by the voiceprint sensor. At the same time, it drives the connecting gear and extension plate to rotate, thereby adjusting the camera angle and aligning the camera with the direction from which the voiceprint is transmitted. This also avoids the situation where the angle of some video surveillance devices remains fixed during installation, making it inconvenient to adjust in real time according to the voiceprint.

[0024] Specifically: the orientation of the camera 307 is adjusted by the rotating device 2, while the angle adjustment device 3 adjusts the angle of the camera 307.

[0025] In one embodiment, the rotating device 2 includes four rotating shafts 201, one of which is equipped with a first forward and reverse motor 202. The bottom of the surface of each of the four rotating shafts 201 is fixedly fitted with a transmission gear 203, and the top of the surface of each of the four rotating shafts 201 is fixedly fitted with a double-belt grooved pulley 204.

The surfaces of the four transmission gears 203 are meshed with a rotating gear 206, and a rotating shaft 207 is fixedly passed through the center of the surface of the rotating gear 206.

[0026] Specifically: the first forward and reverse motor 202 drives the transmission gear 203 and the rotating gear 206 to rotate, and at the same time drives the rotating shaft 207 to rotate, which plays the role of adjusting the orientation.

[0027] In one embodiment, one end of the three rotating shafts 201 is mounted on the bottom of the fixed plate 1 by bearings, the other end of the three rotating shafts 201 is mounted on the top of the fixed disk 102 by bearings, and one end of the surface of another rotating shaft 201 extends through the surface of the fixed disk 102.

[0028] Specifically: The rotating shaft 201 is fixed by the fixing plate 1 and the fixing disk 102, which serves to fix it.

[0029] In one embodiment, the other end of another rotating shaft 201 is mounted on the bottom of the fixed plate 1 via a bearing, one end of the first forward and reverse motor 202 is mounted on the bottom of the fixed plate 102, the top end of the rotating shaft 207 is mounted on the center of the bottom of the fixed plate 1 via a bearing, and the surface of the rotating shaft 207 is movably embedded inside the fixed hole 103.

[0030] Specifically, the rotating shaft 201, the first forward and reverse motor 202, and the rotating shaft 207 are fixed and limited by the fixing plate 1, fixing hole 103, and fixing plate 102, which plays the role of limiting and fixing.

[0031] In one embodiment, the angle adjustment device 3 includes a second forward and reverse motor 301. The output end of the second forward and reverse motor 301 is fixedly connected to a drive shaft 302. A rotating gear 303 is fixedly sleeved on the surface of the drive shaft 302. A connecting gear 304 is meshed with the surface of the rotating gear 303. A fixed shaft 305 is fixedly passed through the center of the surface of the connecting gear 304. An extension plate 306 is installed on one side of the connecting gear 304. A camera 307 is installed at the center of one end of the extension plate 306. Four voiceprint sensors 308 are installed around the camera 307 at one end of the extension plate 306.

[0032] Specifically: The second forward and reverse motor 301 drives the rotating gear 303 and the extension plate 306 to rotate, thereby adjusting the angle of the camera 307 and the voiceprint sensor 308, which serves to adjust the angle.

[0033] In one embodiment, one end of the second forward and reverse motor 301 is mounted on one side of the U-shaped support plate 105, and one end of the drive shaft 302 extends through the surface of the U-shaped support plate 105.

[0034] Specifically, the U-shaped support plate 105 fixes the second forward and reverse motor 301, thus achieving a fixing effect.

[0035] In one embodiment, the other end of the drive shaft 302 is mounted on one side inside the U-shaped support plate 105 via a bearing, and both ends of the fixed shaft 305 are mounted on both sides inside the U-shaped support plate 105 via bearings.

[0036] Specifically, the U-shaped support plate 105 connects and fixes the drive shaft 302 and the fixed shaft 305, thus serving the purpose of connection and fixation.

[0037] Working Principle: The video surveillance device is fixed to the wall or other installation location using multiple bolts on a mounting plate 1. It is then connected to an external power supply via wiring. The first forward / reverse motor 202, the second forward / reverse motor 301, the camera 307, and the voiceprint sensor 308 are electrically connected to and controlled by an external control terminal. A control program is pre-programmed on the external control terminal, connecting the camera 307 and the voiceprint sensor 308. The voiceprint sensor 308 collects and monitors sound wave information in real time and transmits it back to the external control terminal. The control terminal analyzes and processes the sound source direction information transmitted from the voiceprint sensor 308 and starts the first forward / reverse motor 202. The first forward / reverse motor 202 drives the rotating shaft 201 to rotate, simultaneously driving the transmission gear 203 to rotate. The rotation of the transmission gear 203... The extension plate 306 and rotating shaft 207 rotate, transmitting power to the connecting plate 104 and U-shaped support plate 105, adjusting the orientation of the camera 307. This avoids the situation where the orientation of the camera 307 is fixed after installation, preventing the device from rotating according to the direction of the soundprint. When adjusting the angle of the camera 307, the external controller starts the second forward and reverse motor 301 based on the direction of the soundprint determined by the soundprint sensor 308, driving the transmission shaft 302 and rotating gear 303 to rotate. At the same time, it drives the connecting gear 304 and extension plate 306 to rotate, adjusting the angle of the camera 307 and aligning the camera 307 with the direction from which the soundprint is transmitted. This also avoids the situation where the angle of some video surveillance devices remains fixed during installation, making it inconvenient to adjust in real time according to the soundprint.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
