[0002] The on-site audio and video acquisition and transmission system consists of digital cameras, high-definition digital video cameras, portable video recorders, video server terminals, and corresponding connecting cables, charging equipment, and backup batteries; blockchain is a term in the field of information technology; essentially, it is a shared database where data or information can be stored, and on-site video images and synchronized audio can be transmitted to the blockchain database for storage.

[0003] Some existing AI-based audio and video acquisition devices generate a lot of heat during operation due to the powerful AI algorithms. When this heat accumulates and is not dissipated, it reduces the efficiency of the device's algorithms, thus reducing the device's overall efficiency. Furthermore, when the device is designed for internal heat dissipation, some impurities may adhere to the air inlet, causing the cooling protection function to gradually decrease over time, which in turn reduces the efficiency of the AI ​​recognition device. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Therefore, the purpose of this invention is to provide an AI-based audio and video acquisition device and method, which addresses the following problems: In some AI-based audio and video acquisition devices, the powerful AI algorithm generates excessive heat during operation, leading to a decrease in algorithm efficiency and consequently, reduced device performance.

[0014] As a preferred embodiment of the AI-based audio and video acquisition device and method of the present invention, the ventilation unit includes a third connecting shaft disposed on the inner surface of the fixed plate behind the rotating shaft, a third gear disposed on the outer surface of the third connecting shaft and meshing with the second gear, a second fan blade disposed on the outer surface of the third connecting shaft below the third gear, and a third connecting plate disposed on the upper surface of the fixed plate above the third gear.

[0015] As a preferred embodiment of the AI-based audio and video acquisition device and method of the present invention, the ventilation unit further includes a rubber sleeve disposed on the inner surface of the third connecting plate, a limiting plate disposed on the inner surface of the rubber sleeve, and a clamping plate disposed on the rear surface of the limiting plate and connected to the third connecting plate by stripes.

AI technology is then used to perform specific analysis on the audio and video signals to extract audio and image features from the processed signals.

[0020] Step 2: During the AI's processing of audio and video signals, the acquisition device itself generates a lot of heat. The structure of the protection unit cools down the internal control board and camera structure of the acquisition device by processing the outside air, thereby maintaining the continuous high-efficiency use of the acquisition device. The worm gear connection structure in the protection unit deflects external impurities away from the air intake position. The AI ​​algorithm needs to randomly select some features and then use them to train the model.

[0021] Step 3: When outside air enters, it is processed by the structure of the protective unit. When the air carries the heat and some impurities inside the main body of the collection device out from the outlet of the first connecting shaft, the multiple structures inside the rubber sleeve facilitate the cleaning of the inside of the structure.

[0022] Step 4: AI algorithms can use models to infer new audio and video data. Finally, the model's output needs to be transformed into a readable data format, such as text, charts, or recommendations, using AI algorithms.

[0023] The beneficial effects of this invention are:

[0024] 1. Through the cooperation between the structures, the internal temperature of the AI-based audio and video acquisition device can be effectively protected and cooled, so that the device itself can maintain high-efficiency continuous operation. By analyzing and acquiring audio and video through AI algorithms, the required data can be obtained relatively quickly, thus maintaining high-efficiency operation.

[0025] 2. Through the cooperation between the structures, the accumulation of impurities generated during the operation of the device can be effectively collected and processed, thereby quickly and effectively cleaning the device itself and keeping it aesthetically pleasing.

[0026] 3. Through the cooperation between the structures, the air entering the device can be effectively discharged, the fine dust brought out of the device can be collected and treated, and the internal structure of the device can be easily processed, so that the device can work continuously and efficiently.

[0041] Example 1

[0042] An audio and video acquisition device and method based on AI recognition, comprising:

[0043] The main unit 100 includes a data acquisition device body 101, a bracket 102 fixedly connected to the lower surface of the data acquisition device body 101 by screws, a fixing frame 103 on the lower surface of the bracket 102, a first connecting plate 104 on the rear surface of the fixing frame 103, a plurality of screws 105 slidably connected to the front surface of the first connecting plate 104 by threads, a camera 106 on the front surface of the data acquisition device body 101, and a control main board 107 on the inner bottom surface of the data acquisition device body 101.

[0044] The protective unit 200 includes a fixing plate 201 disposed on the upper surface of the acquisition device body 101, a motor 202 disposed on the inner surface of the fixing plate 201, a second connecting plate 215 disposed on the upper surface of the fixing plate 201 in front of the motor 202, a rotating shaft 203 disposed at the output end of the motor 202, a second gear 214 disposed on the outer surface of the rotating shaft 203, a first connecting shaft 204 disposed on the inner surface of the fixing plate 201 in front of the rotating shaft 203, a first gear 205 disposed on the outer surface of the first connecting shaft 204 and meshing with the second gear 214, a first fan blade 211 disposed on the outer surface of the first connecting shaft 204 below the first gear 205, and a fan blade 211 disposed on the upper surface of the first connecting shaft 204. The system includes a second connecting shaft 206, a worm gear 207 disposed on the outer surface of the second connecting shaft 206, multiple first connecting rods 209 disposed on the inner surface of the second connecting plate 215 in front of the second connecting shaft 206, a worm 208 disposed between two first connecting rods 209 and slidably connected to the worm gear 207, a scraper 210 disposed on the inner surface of the second connecting plate 215 and reciprocatingly threaded to the first connecting rods 209, a filter plate 212 disposed on the upper surface of the second connecting plate 215, and a filter groove 213 disposed on the inner surface of the second connecting plate 215 and matching the scraper 210. A ventilation unit 400 is disposed on the upper surface of the fixing plate 201, and an auxiliary unit 300 is disposed on the upper surface of the second connecting plate 215.

[0045] Specifically, when using this device, the camera 106 in the acquisition device body 101 of the main unit 100 needs to acquire external audio and video signals. Next, the audio and video signals need to be preprocessed through the control motherboard 107. AI technology is used to perform specific analysis on the audio and video signals, extracting audio and image features from the processed signals. When using the device, the motor 202 drives the rotating shaft 203 to rotate, which in turn drives the second gear 214 to rotate. The second gear 214 then drives the first gear 205 to rotate, which in turn drives the first connecting shaft 204 to rotate. The first connecting shaft 204 then drives the first fan blade 211 to rotate. The multiple slots in the first gear 205 allow air to pass through normally. The air pressure generated by the rotation of the first fan blade 211 forces the air through the filter plate 212 above the second connecting plate 215 before it enters the air vent in the filter tank 213. The air is filtered through the holes and slots inside the fixed plate 201. During the filtration process, dust accumulates in the filter groove 213. The first connecting shaft 204 drives the second connecting shaft 206 to rotate, which in turn drives the worm gear 207 to rotate. The worm gear 207 then drives the worm 208 to rotate. The worm 208, through the reciprocating thread of the first connecting rod 209, drives the scraper 210 to reciprocate in the filter groove 213 inside the second connecting plate 215. This pushes the impurities attached to the filter groove 213 towards the left and right sides of the second connecting plate 215, separating the impurities from the second connecting plate 215. Through the cooperation between the structures, the internal structure of the AI-based audio and video acquisition device can be effectively protected and cooled, allowing the device to maintain high-efficiency continuous operation. By analyzing and acquiring audio and video through AI algorithms, the required data can be obtained relatively quickly, thus maintaining high-efficiency operation.

[0046] Example 2

[0047] An AI-based audio and video acquisition device, based on embodiment 1, includes an auxiliary unit 300, which comprises a sieve plate 301 rotatably connected to the front end of the upper surface of a second connecting plate 215 via a shaft; a storage box 302 located on the outer surfaces of the left and right sides of the second connecting plate 215 corresponding to the positions of the scraper 210; a sponge plate 306 located on the inner surface of a fixing plate 201 below the first fan blade 211; a retaining plate 303 located on the outer surface of the storage box 302 near the second connecting shaft 206; a first connecting shaft 204 located on the outer surface of the retaining plate 303 near the second connecting shaft 206; a slot 307 located on the upper surface of the second connecting plate 215 matching the storage box 302; a sealing plate 308 rotatably connected to the outer surface of the storage box 302 away from the second connecting shaft 206 via a shaft; and a sealing strip 305 fixedly connected between the outer surface of the sealing plate 308 near the second connecting shaft 206 and the storage box 302.

[0048] Specifically, impurities enter the storage box 302 in the auxiliary unit 300 structure. The sieve plate 301 is used to assist the filter plate 212. A thin layer of paper towel can be placed between the sieve plate 301 and the second connecting plate 215 to prevent dust from entering. The material is inexpensive, has strong usability, and is easy to replace. After the dust enters the sieve plate 301, the storage box 302 can be pulled to both sides to separate the card plate 303 from the card slot 307. This causes the storage box 302 to separate the card plate 303 from the limiting plate 304 and the second connecting plate 215. Then, under the action of the shaft, the sieve plate 301 is opened to replace the paper towel. Next, under the action of the shaft, the 309 sealed by the sponge plate 306 is opened, allowing the storage box 302 to be opened to process the dust stored inside. The sponge plate 306 helps to prevent dust from entering the collection device body 101. Through the cooperation between the structures, the impurities generated during the operation of the device can be effectively collected and processed, thereby quickly and effectively cleaning the device itself and keeping the device aesthetically pleasing.

[0049] Example 3

[0050] An AI-based audio and video acquisition device, based on Embodiment 1, includes a ventilation unit 400, comprising a third connecting shaft 402 disposed on the inner surface of a fixed plate 201 behind a rotating shaft 203, a third gear 401 disposed on the outer surface of the third connecting shaft 402 and meshing with a second gear 214, a second fan blade 403 disposed on the outer surface of the third connecting shaft 402 below the third gear 401, a third connecting plate 404 disposed on the upper surface of the fixed plate 201 above the third gear 201, and a third connecting plate 404 disposed on the third connecting shaft 202 behind a rotating shaft 203. The rubber sleeve 406 on the inner surface of the connecting plate 404, the limiting plate 408 on the inner surface of the rubber sleeve 406, the clamping plate 407 on the rear surface of the limiting plate 408 and the third connecting plate 404 by stripes, the slide plate 409 between the two clamping plates 407, the second connecting rod 411 on the front surface of the slide plate 409, the wiping plate 412 on the front surface of the second connecting rod 411 and the rubber sleeve 406 that are slidably connected, the multiple conical grooves 405 on the inner surface of the pull strip 410, and the multiple pull strips 410 on the rear surface of the slide plate 409.

[0051] Specifically, when air enters the body 101 of the collection device and carries away heat and some impurities, it is discharged through the third connecting plate 404. During the air discharge, the impurities in the air are collected by the rubber sleeve 406, while preventing dust from adhering to the inside of the fixed plate 201 and the first connecting shaft 204. The cooperation between the clamping plate 407 and the limiting plate 408 can help stabilize the third connecting plate 404. Finally, by pulling the pull bar 410, the 309 can be moved to the rear of the body 101 of the collection device. Then, the slide plate 409 slides out of the third connecting plate 404 through the second connecting rod 411, carrying away the dust. The conical groove 405 can effectively prevent dust from entering the body 101 of the collection device when it is idle. Through the cooperation between the structures, the air entering the device can be effectively discharged, and the fine dust brought out of the device can be collected and processed. It also facilitates the processing of the internal structure of the device, thereby enabling the device to work continuously and efficiently.

[0052] A method for using an AI-based audio and video acquisition device, characterized by comprising the following steps:

[0053] SI: First, the external audio and video signals need to be collected by the camera 106 in the acquisition device body 101 structure of the main unit 100. Next, the audio and video signals need to be preprocessed by the control motherboard 107 structure. The audio and video signals are then analyzed by AI technology to extract audio and image features from the processed signals.

[0054] S2: During the AI's processing of audio and video signals, the acquisition device body 101 generates a lot of heat. The structure of the protection unit 200 cools down the internal control motherboard 107 and camera 106 of the acquisition device body 101 by processing the outside air, thereby maintaining the continuous high-efficiency use of the acquisition device body 101. The worm gear 208 in the protection unit 200 structure removes external impurities from the air intake position. The AI ​​algorithm needs to randomly select some features and then use them to train the model.

[0055] S3: When outside air enters, it is processed by the structure of the protection unit 200. When the air carries the heat and some impurities inside the collection device body 101 out from the outlet of the first connecting shaft 204, the multiple structures inside the rubber sleeve 406 facilitate the cleaning of the inside of the structure.

[0056] S4: AI algorithms can use models to reason about new audio and video data. Finally, the model's output needs to be transformed into a readable data format, such as text, charts, or recommendations, using AI algorithms.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.

Next, the audio and video signals need to be preprocessed by the structure of the control motherboard (107). The audio and video signals are analyzed by AI technology to extract audio and image features from the processed signals. Step 2: During the AI's processing of audio and video signals, the main body of the acquisition device (101) will generate a lot of heat. The structure of the protection unit (200) will cool down the control motherboard (107) and camera (106) inside the main body of the acquisition device (101) by processing the outside air. The worm gear (208) in the structure of the protection unit (200) will deflect external impurities away from the air intake position. The AI ​​algorithm will randomly select some features and then use them to train the model. Step 3: When outside air enters, it is processed by the structure of the protective unit (200). When the air carries the heat and some impurities inside the main body (101) of the collection device out from the outlet of the first connecting shaft (204), the multiple structures inside the rubber sleeve (406) facilitate the cleaning of the inside of the structure. Step 4: AI algorithms can use models to infer new audio and video data. Finally, the output of the model needs to be converted into a readable data format through AI algorithms.
