Description

Technical Field

[0001] This invention relates to the field of video conferencing technology, specifically to a cloud server-based video conferencing system and apparatus. Background Technology

[0002] With the advent of the information age, traditional office meetings have also changed. The use of information technology for video conferencing has solved the problem of large-scale modern enterprises with widely distributed personnel, making it impossible to hold meetings in a centralized manner. As a result, cloud-based video conferencing systems and devices have emerged. With the continuous development of technology, the development trend of cloud-based video conferencing systems and devices is becoming increasingly diversified.

[0003] Existing cloud-based video conferencing systems and devices mainly suffer from the following technical defects: Traditional cloud-based video conferencing systems can only create, receive, and send video conferences, making their functions too limited. They cannot achieve automatic close-up of the video conference screen following the sound, resulting in poor video conferencing effects. At the same time, the operating equipment of traditional cloud-based video conferencing systems uses fixed cameras, which has very limited angles for picking up images and sound. Summary of the Invention

[0004] The purpose of this invention is to provide a cloud server-based video conferencing system and apparatus to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cloud server-based video conferencing system, comprising a cloud server, a central processing unit, a tracking module, a data acquisition module, a connection module, and a visual module. The cloud server is used to respond to and process service requests from the terminal, and also to store video conferencing data. The central processing unit is used to control and coordinate the operation of each module. The tracking module tracks the sound in the video conference using a sound recognition device and a motion mechanism to ensure that changes in the video image are consistent with changes in the sound. The connection module includes a sending unit and a receiving unit. The sending unit sends the received video and audio signals to the cloud server to establish a video creation group. The receiving unit is used to receive video and audio signals obtained by other users in the video creation group from the cloud server.

[0006] Furthermore, the visual module includes an IoT gateway, a control box, and a screen recording unit. The IoT gateway transmits video creation group video data from the cloud server to the control box. The control box projects real-time video data onto a large visual screen through a visualization display module. At the same time, the control box transmits video conferencing data to the screen recording unit for screen recording and transmits the recorded video data to the cloud server for storage.

[0007] Furthermore, the acquisition module includes an image and sound acquisition unit, which acquires images and sounds from the video conference using a camera and a microphone.

[0008] The operating device of the cloud server-based video conferencing system includes a base, a first movable mechanism is fixedly installed on the inner side wall of the base, the first movable mechanism is provided with an adjustment device and a buffer device, a sound capture device is fixedly installed on the upper part of the first movable mechanism, a protective device is fixedly connected to the outer side of the middle part of the first movable mechanism, and a sound receiving shell is fixedly connected to the outer side of the first movable mechanism. The first movable mechanism includes a first motor, a first rotating shaft, a connecting block, a microphone, a connecting rod, and a second movable mechanism. The first motor is fixedly connected to the inner side wall of the base. The first rotating shaft is drivenly connected to the upper side of the first motor. The connecting block is fixedly connected to the upper side of the first rotating shaft. The microphone is fixedly connected to the upper side of the connecting block. The connecting rod is fixedly connected to the upper side of the microphone. The second movable mechanism is provided on the connecting rod. A microphone housing is fixedly connected to the outer side of the microphone along its axial direction.

[0009] Furthermore, the structure of the second active mechanism includes a second motor, a second rotating shaft, a support rod, and a camera. The second motor is fixedly connected to the side wall of the connecting rod. The second rotating shaft is drivenly connected to the side of the second motor near the connecting rod. The second rotating shaft passes through the connecting rod. The support rod is fixedly connected to the outer side of the second rotating shaft along its axial direction. A camera is provided on the upper side of the support rod.

[0010] Furthermore, the control device includes a movable rod, a first spring, a toggle block, a sliding rheostat, and a housing. The movable rod is fixedly connected to the lower side of the camera, and the toggle block is fixedly connected to the lower side of the movable rod. The housing is fixedly connected to the upper side of the support rod, and the sliding rheostat is fixedly connected to the inner wall of the housing. The movable rod passes through the housing and extends into the interior of the housing. The toggle block slides on the sliding rheostat, and the first spring is sleeved on the axial outer side of the movable rod.

[0011] While the camera is moving, there is a period when the camera drives the movable rod to compress the first spring, which in turn causes the toggle block to slide down on the sliding rheostat, thereby changing the internal resistance of the sliding rheostat. Since the inside of the circular shell is filled with a current transformer, and the sliding rheostat and the current transformer are electrically connected, the farther the toggle block slides down, the smaller the internal resistance of the sliding rheostat becomes, and the greater the current flowing into the current transformer. After the current is applied, the density of the current transformer changes positively with the intensity of the current. Furthermore, the buffer device includes a first connecting seat, a first moving rod, an impeller, a circular shell, a rotating column, a second moving rod, and a second connecting seat. The upper side of the support rod is fixedly connected to a uniformly distributed first connecting seat. The inner side of the first connecting seat is rotatably connected to a first moving rod. The side wall of the first moving rod is fixedly connected to a circular shell. The inner side of the first moving rod is rotatably connected to a rotating column. The outer side of the rotating column is fixedly connected to a second moving rod. The upper outer side of the second moving rod is rotatably connected to a second connecting seat. The outer side of the rotating column and inside the circular shell is fixedly connected to an impeller. The rotating column penetrates the circular shell and extends to the outer side of the circular shell.

[0012] This allows the concentration of the current variant to change in a positive direction following the downward movement rate of the camera, thereby limiting the rotation of the impeller. With the combined action of the first connecting seat, the first moving rod, the rotating column, the circular shell, the second moving rod, and the second connecting seat, the camera is buffered, thus achieving a stable video conferencing image. Furthermore, the sound capture device includes a protective shell, a megaphone, a controller, and a first megaphone plate. The protective shell is fixedly connected to the lower side of the camera. The protective shell has evenly distributed through holes. Evenly distributed megaphones are fixedly connected to the inner wall of the protective shell. The megaphones correspond to the through holes on the protective shell. The first megaphone plate is fixedly connected to the inner wall of the protective shell. The controller is fixedly connected to the inner wall of the protective shell. The controller penetrates the protective shell and extends into the interior of the protective shell.

[0013] The system controls the camera to capture the video conference image and simultaneously picks up the sound from the video conference through the microphone. Because of the first protective plate, the second amplification plate, the second protective plate, and the third amplification plate, the sound from the video conference can be amplified and picked up, ensuring the stability of the sound. At the same time, the sound from the video conference is amplified by the microphone and the first amplification plate and enters the controller, allowing the controller to determine the specific location of the sound emitted. Based on the location information, the controller transmits electrical signals to the system, which then activates the first and second motors. The first motor drives the first rotating shaft to rotate, and the second motor drives the second rotating shaft to rotate, thereby enabling the camera to continuously move in sync with the speaker, ensuring the clarity and continuity of the video conference and improving the overall video conferencing effect. Furthermore, the protective device includes a mounting plate, a first protective plate, a second amplification plate, a control device, and a side protection mechanism. The mounting plate is fixedly connected to the outer side of the microphone along its axis. The first protective plate is hinged to the upper side of the mounting plate. The second amplification plate is fixedly connected to the inner wall of the first protective plate. The control device is fixedly connected between the first protective plate and the connecting rod. A side protection mechanism is also provided on the upper side of the mounting plate. The control device includes a mounting block, a connecting column, an electric telescopic rod, a moving block, and a mounting base. The mounting block is fixedly connected to the upper side of the first protective plate, and the connecting column is fixedly connected to one side of the mounting block. The electric telescopic rod is rotatably connected to the outer side of the connecting column. The moving block is fixedly connected to the upper side of the electric telescopic rod, and the mounting base is rotatably connected to the outer side of the moving block. The mounting base and the connecting rod are fixedly connected.

[0014] Furthermore, the side protection mechanism includes a second protective plate and a third amplification plate. The second protective plate is hinged to the upper side of the mounting plate, and the third amplification plate is fixedly connected to the inner side of the second protective plate. Before conducting a video conference, place this device on the conference table, activate the electric telescopic rod to extend it, causing the electric telescopic rod to drive the first and second protective plates to open outwards around the connecting block via the connecting column. When the first and second protective plates are at a 60-degree angle to the connecting block, stop the electric telescopic rod, and then start the camera to conduct the video conference.

[0015] Compared with the prior art, the present invention provides a video conferencing system and apparatus based on a cloud server, which has the following beneficial effects: 1. This invention utilizes the coordinated action of a tracking module, a data acquisition module, and a visual module. The tracking module tracks the sound during a video conference using a sound recognition device and a motion mechanism, ensuring that changes in the video image are consistent with changes in the sound. Simultaneously, the video conference image and sound are captured clearly. Furthermore, the visual module records the screen during the video conference using a screen recording unit, thus achieving the effect of recording video conference data and improving the overall effect of the video conference.

[0016] 2. This invention utilizes the coordinated action of the electric telescopic rod, connecting column, first protective plate, second protective plate, connecting block, camera, microphone, second amplification plate, and third amplification plate to provide protection for the microphone. This ensures that the microphone is in a sealed state when the device is not in use, thus isolating it from dust and preventing collisions. At the same time, a converging effect is formed around the microphone, thereby enhancing the amplification effect and maintaining the clarity of sound pickup.

[0017] 3. This invention achieves the purpose of limiting the rotation of the impeller by utilizing the cooperation between the camera, movable rod, first spring, toggle block, sliding rheostat, circular shell, impeller, second moving rod, and the second connecting seat and the first connecting seat. This is achieved by making the concentration of the current variant change in a positive direction as the camera moves downward, thereby buffering the camera and stabilizing the video conferencing image.

[0018] 4. This invention achieves the synchronous movement of the camera's image pickup following the sound source through the coordinated action of the megaphone, the first megaphone board, the controller, the first motor, the second motor, the first rotating shaft, and the second rotating shaft. This ensures the clarity and continuity of the video conference, improves the video conference effect, and solves the problem that fixed cameras have very limited image and sound pickup angles.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0022] Please see Figures 1-13 A cloud-based video conferencing system includes a cloud server, a central processing unit, a tracking module, a data acquisition module, a connection module, and a visual module. The cloud server is used to respond to and process service requests from the terminal, and also to store video conferencing data. The central processing unit is used to control and coordinate the operation of each module. The tracking module tracks the sound in the video conference using a sound recognition device and a motion mechanism to ensure that changes in the video image are consistent with changes in the sound. The connection module includes a sending unit and a receiving unit. The sending unit sends the received video and audio signals to the cloud server to establish a video creation group. The receiving unit is used to receive video and audio signals obtained by other users in the video creation group from the cloud server.

[0023] Furthermore, the visual module includes an IoT gateway, a control box, and a screen recording unit. The IoT gateway transmits video creation group video data from the cloud server to the control box. The control box projects real-time video data onto a large visual screen through a visualization display module. At the same time, the control box transmits video conferencing data to the screen recording unit for screen recording and transmits the recorded video data to the cloud server for storage.

[0024] Furthermore, the acquisition module includes an image and sound acquisition unit, which acquires images and sounds from the video conference using a camera and a microphone.

[0025] The operating device of the cloud server-based video conferencing system includes a base 1, a first movable mechanism 2 fixedly installed on the inner side wall of the base 1, an adjustment device 3 and a buffer device 4 provided on the first movable mechanism 2, a sound capture device 5 fixedly installed on the upper part of the first movable mechanism 2, a protective device 6 fixedly connected to the outer side of the middle part of the first movable mechanism 2, and a sound receiving shell 7 fixedly connected to the outer side of the first movable mechanism 2. The first movable mechanism 2 includes a first motor 21, a first rotating shaft 22, a connecting block 23, a microphone 24, a connecting rod 25, and a second movable mechanism 26. The first motor 21 is fixedly connected to the inner wall of the base 1. The first rotating shaft 22 is drivenly connected to the upper side of the first motor 21. The connecting block 23 is fixedly connected to the upper side of the first rotating shaft 22. The microphone 24 is fixedly connected to the upper side of the connecting block 23. The connecting rod 25 is fixedly connected to the upper side of the microphone 24. The second movable mechanism 26 is provided on the connecting rod 25. The microphone shell 7 is fixedly connected to the outer side of the microphone 24.

[0026] Furthermore, the structure of the second active mechanism 26 includes a second motor 261, a second rotating shaft 262, a support rod 263, and a camera 264. The second motor 261 is fixedly connected to the side wall of the connecting rod 25. The second rotating shaft 262 is drivenly connected to the side of the second motor 261 near the connecting rod 25. The second rotating shaft 262 passes through the connecting rod 25. The support rod 263 is fixedly connected to the outer side of the second rotating shaft 262. The camera 264 is provided on the upper side of the support rod 263.

[0027] Furthermore, the control device 3 includes a movable rod 31, a first spring 32, a toggle block 33, a sliding rheostat 34, and a housing 35. The movable rod 31 is fixedly connected to the lower side of the camera 264, and the toggle block 33 is fixedly connected to the lower side of the movable rod 31. The housing 35 is fixedly connected to the upper side of the support rod 263, and the sliding rheostat 34 is fixedly connected to the inner wall of the housing 35. The movable rod 31 passes through the housing 35 and extends into the interior of the housing 35. The toggle block 33 slides on the sliding rheostat 34, and the first spring 32 is sleeved on the axial outer side of the movable rod 31.

[0028] While the camera 264 is moving, there is a period when the camera 264 drives the movable rod 31 to compress the first spring 32, and at the same time drives the toggle block 33 to slide downward on the sliding rheostat 34, thereby changing the internal resistance of the sliding rheostat 34. Since the inside of the circular shell 44 is filled with a current variant, and the sliding rheostat 34 is electrically connected to the current variant, the farther the toggle block 33 slides downward, the smaller the internal resistance of the sliding rheostat 34, and the larger the current flowing into the current variant. After the current is flowing into the current variant, the density of the current variant changes positively with the intensity of the current. Furthermore, the buffer device 4 includes a first connecting seat 41, a first moving rod 42, an impeller 43, a circular shell 44, a rotating column 45, a second moving rod 46, and a second connecting seat 47. The upper side of the support rod 263 is fixedly connected to the evenly distributed first connecting seat 41. The inner side of the first connecting seat 41 is rotatably connected to the first moving rod 42. The side wall of the first moving rod 42 is fixedly connected to the circular shell 44.

The upper outer side of the second moving rod 46 is rotatably connected to the second connecting seat 47. The outer side of the rotating column 45 and inside the circular shell 44 is fixedly connected to the impeller 43. The rotating column 45 penetrates the circular shell 44 and extends to the outer side of the circular shell 44.

[0029] This enables the concentration of the current variant to change in a positive direction as the camera 264 moves downward, thereby limiting the rotation of the impeller 43. With the combined action of the first connecting seat 41, the first moving rod 42, the rotating column 45, the circular shell 44, the second moving rod 46, and the second connecting seat 47, the camera 264 is buffered, thus achieving a stable video conferencing image. Furthermore, the sound capture device 5 includes a protective shell 51, a megaphone 52, a controller 53, and a first megaphone plate 54. The protective shell 51 is fixedly connected to the lower side of the camera 264. The protective shell 51 has evenly distributed through holes. Evenly distributed megaphones 52 are fixedly connected to the inner wall of the protective shell 51. The megaphones 52 correspond to the through holes on the protective shell 51. The first megaphone plate 54 is fixedly connected to the inner wall of the protective shell 51. The controller 53 is fixedly connected to the inner wall of the protective shell 51. The controller 53 penetrates the protective shell 51 and extends into the interior of the protective shell 51.

[0030] The system controls the camera 264 to capture the video conference image, and simultaneously uses the microphone 24 to capture the sound of the video conference. Due to the presence of the first protective plate 62, the second amplification plate 63, the second protective plate 651, and the third amplification plate 652, the sound of the video conference can be amplified and captured, ensuring the stability of the sound. At the same time, the sound of the video conference is amplified by the microphone 52 and the first amplification plate 54 and enters the controller 53, allowing the controller 53 to determine the specific location of the sound emitted by the controller. Based on the location information, the controller 53 transmits electrical signals to the system, which then activates the first motor 21 and the second motor 261. The first motor 21 drives the first rotating shaft 22 to rotate, and the second motor 261 drives the second rotating shaft 262 to rotate. This enables the camera 264 to continuously move synchronously with the speaker, thereby ensuring the clarity and continuity of the video conference and improving the video conference effect. Furthermore, the protective device 6 includes a mounting plate 61, a first protective plate 62, a second amplifying plate 63, a control device 64, and a side protection mechanism 65. The mounting plate 61 is fixedly connected to the outer side of the microphone 24. The first protective plate 62 is hinged to the upper side of the mounting plate 61. The second amplifying plate 63 is fixedly connected to the inner wall of the first protective plate 62. The control device 64 is fixedly connected between the first protective plate 62 and the connecting rod 25. The side protection mechanism 65 is also provided on the upper side of the mounting plate 61. The control device 64 includes a mounting block 641, a connecting column 642, an electric telescopic rod 643, a moving block 644, and a mounting base 645. The mounting block 641 is fixedly connected to the upper side of the first protective plate 62. The connecting column 642 is fixedly connected to one side of the mounting block 641. The electric telescopic rod 643 is rotatably connected to the outer side of the connecting column 642. The moving block 644 is fixedly connected to the upper side of the electric telescopic rod 643. The mounting base 645 is rotatably connected to the outer side of the moving block 644. The mounting base 645 is fixedly connected to the connecting rod 25.

[0031] Furthermore, the side protection mechanism 65 includes a second protective plate 651 and a third amplification plate 652. The second protective plate 651 is hinged to the upper side of the mounting plate 61, and the third amplification plate 652 is fixedly connected to the inner side of the second protective plate 651. Before conducting a video conference, place the device on the conference table, activate the electric telescopic rod 643 to extend it, so that the electric telescopic rod 643 drives the first protective plate 62 and the second protective plate 651 to open outward with the connecting block 23 as the center through the connecting column 642. The first protective plate 62, the second protective plate 651 and the connecting block 23 form a 60-degree angle, then stop the electric telescopic rod 643, and then start the camera 264 to conduct the video conference.

[0032] The specific usage and function of this embodiment are as follows: In use, before conducting a video conference, place the device on the conference table, activate the electric telescopic rod 643 to extend it, so that the electric telescopic rod 643 drives the first protective plate 62 and the second protective plate 651 to open outward with the connecting block 23 as the center through the connecting column 642. The first protective plate 62, the second protective plate 651 and the connecting block 23 form a 60-degree angle, then stop the electric telescopic rod 643, and then start the camera 264 to conduct a video conference. The system controls camera 264 to capture the video conference image, and simultaneously uses microphone 24 to capture the sound of the video conference. The presence of a first protective plate 62, a second amplification plate 63, a second protective plate 651, and a third amplification plate 652 amplifies and captures the sound, ensuring sound stability. Meanwhile, the sound from the video conference is amplified by the microphone 52 and the first amplification plate 54 and enters the controller 53, allowing the controller 53 to determine the specific location of the sound. Based on this location information, the controller 53 transmits an electrical signal to the system, which then activates the first motor 21 and the second motor 261. The first motor 21 drives the first rotating shaft 22 to rotate, and the second motor 261 drives the second rotating shaft 262 to rotate. This ensures that the camera 264's captured image moves synchronously with the sound source, thereby guaranteeing the clarity and continuity of the video conference and improving its effectiveness. While the camera 264 is moving, there is a period when the camera 264 drives the movable rod 31 to compress the first spring 32, and at the same time drives the toggle block 33 to slide downward on the sliding rheostat 34, thereby changing the internal resistance of the sliding rheostat 34. Since the inside of the circular shell 44 is filled with a current variant, and the sliding rheostat 34 is electrically connected to the current variant, the farther the toggle block 33 slides downward, the smaller the internal resistance of the sliding rheostat 34, and the larger the current flowing into the current variant. After the current is flowing into the current variant, the density of the current variant changes positively with the intensity of the current. This allows the density of the current variant to change in a positive direction as the camera 264 moves downward, thereby limiting the rotation of the impeller 43. With the combined action of the first connecting seat 41, the first moving rod 42, the rotating column 45, the circular shell 44, the second moving rod 46, and the second connecting seat 47, the camera 264 is buffered, thus achieving a stable video conferencing image.
