Description

Technical Field

[0001] This utility model relates to the field of visual effects switching technology, and in particular to a live streaming intelligent switching device. Background Technology

[0002] In today's era of rapid development in digital media, the live streaming industry is booming. As an indispensable key piece of equipment in the live streaming process, the performance of the video effects switcher has a crucial impact on the quality and effect of the live stream. Traditional video effects switchers mainly rely on manual operation. During the live stream, operators need to simultaneously manage numerous function buttons, sliders, and knobs to switch between video feeds and adjust effects. For example, in a comprehensive live streaming event, there may be frequent switching between multiple video sources and the timely application of various effects (such as fade-in / fade-out, wipe, rotation, zoom, etc.). Operators must remain highly focused at all times, manually pressing the corresponding buttons to select video feeds, pushing and pulling sliders to control the transition of effects, and rotating knobs to adjust video parameters (such as brightness, contrast, color saturation) and effect parameters (such as speed, intensity, etc.).

[0003] However, this manual operation method has many drawbacks. On the one hand, as live streaming content becomes increasingly rich and complex, the operation process becomes extremely cumbersome, requiring operators to constantly switch between different operating components. This significantly reduces the operation speed and makes it difficult to meet the demand for fast and accurate switching of images during fast-paced live streaming. On the other hand, prolonged manual operation can easily cause operator fatigue and mental stress, leading to frequent operational errors, such as pressing the wrong button, inaccurate lever movement, and deviation in knob rotation angle. These errors may cause problems such as stuttering, inconsistent special effects, and sudden changes in image quality, seriously affecting the smoothness and watchability of the live stream, and may even have a negative impact on the overall effect of the live stream, reducing the viewing experience and satisfaction of the audience, and thus affecting the commercial value and dissemination effect of the live streaming event. In view of this, this paper proposes a live streaming intelligent switching device. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing image effects switcher mainly relies on manual operation, and to propose a live broadcast intelligent switching device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A live streaming intelligent switching device includes a visual effects switching console, an electrical control box is installed above the visual effects switching console, and a power module and a programmable logic controller are fixedly installed inside the electrical control box.

[0007] The bottom surface of the electrical control box is vertically connected to several first electric telescopic rods for automatically pressing buttons on the screen effect switching platform, second electric telescopic rods for automatically pushing and pulling push rods on the screen effect switching platform, and stepper motors for automatically rotating knobs on the screen effect switching platform. The first electric telescopic rods, stepper motors, and second electric telescopic rods are all connected to the power module and programmable logic controller via wires.

[0008] Preferably, the cylinder and the control box of the second electric telescopic rod are fixedly connected, and the extended end of the second electric telescopic rod is fixedly connected to a connecting seat. A slot for fitting the push rod of the screen effect switching platform is provided below the connecting seat. A linear displacement sensor is arranged parallel above the second electric telescopic rod, and the two ends of the linear displacement sensor are fixedly connected to the cylinder and the connecting seat of the second electric telescopic rod, respectively.

[0009] Preferably, the housing of the stepper motor and the control box are fixedly connected, and the output end of the rotor of the stepper motor is coaxially connected to a sleeve. A positioning groove for fitting and connecting the knob on the screen effects switching platform is provided below the sleeve.

[0010] Preferably, the cylinder and the control box in the first electric telescopic rod are fixedly connected, and a rubber sleeve is provided around the protruding end of the first electric telescopic rod.

[0011] Preferably, a pressure sensor is provided inside the rubber sleeve, and the upper surface of the pressure sensor is fixedly connected to the protruding end of the first electric telescopic rod.

[0012] Preferably, corner rods are vertically installed at the four corners of the visual effects switcher, and the four corner rods are respectively fitted into the outer periphery of the four corner edges of the visual effects switcher.

[0013] Preferably, a touch screen is fixedly installed on the top of the electrical control box, and a motor driver, a voice recognition module, and a voice synthesis module are also fixedly installed inside the electrical control box.

[0014] Preferably, the left and right side walls of the electrical control box are provided with a number of corresponding heat dissipation holes.

[0015] Compared with the prior art, the present invention provides a live broadcast intelligent switching device, which has the following beneficial effects:

[0016] 1. Significantly improves automation level and frees up manpower for operation.

[0017] Compared to traditional manually operated video effects switchers, this intelligent live streaming switcher introduces advanced voice recognition control and automated operation functions triggered by specific scenarios. Operators only need to speak voice commands such as "switch to the next video effect" or "adjust screen brightness to increase," and the voice recognition module will quickly convert them into operation commands, driving the corresponding electric components to complete the action. This eliminates the need for manually pressing buttons or turning knobs one by one, greatly improving operation speed and convenience. Especially during fast-paced live streaming, it can quickly respond to various operational needs, significantly reducing the tediousness and error probability of manual operation. Simultaneously, operators can pre-set a series of detailed operation procedures on the touchscreen according to different live streaming scenarios, including the video switching order and effects settings. When the corresponding scenario conditions are met during the live stream, this intelligent live streaming switcher will automatically and accurately execute the preset operations, achieving intelligent switching of live stream footage and the presentation of effects, making the live streaming process smoother and more professional. This fundamentally changes the inefficient mode of traditional manual operation, bringing a brand-new, highly efficient experience to live streaming work. This is the most significant and groundbreaking improvement compared to existing technologies.

[0018] 2. Significantly improves operational accuracy and optimizes screen presentation.

[0019] 2.1 Improved button operation accuracy:

[0020] The first electric telescopic pole is equipped with a pressure sensor feedback mechanism, which can precisely control the pressing force compared with traditional manual buttons. In live broadcast scenarios with frequent screen switching, it can accurately trigger the function of each button, effectively avoiding screen switching errors caused by improper button operation force. At the same time, it can also protect the buttons from damage due to excessive pressure, extend the button's service life, and ensure that every button operation is accurate, thereby improving the stability and reliability of live broadcast screen switching.

[0021] 2.2 Improved accuracy of push rod operation:

[0022] The second electric telescopic rod, combined with a linear displacement sensor, achieves precise linear movement control of the rod compared to manual push-pull rods. When implementing special effects such as fade-in / fade-out and wipe effects, it can accurately control the transition effect of the image, making the image transition smoother and more natural. It avoids problems such as uneven or incomplete rod movement that may occur with manual operation, greatly improving the visual experience of live streaming and allowing viewers to enjoy smoother and more coherent image effect transitions.

[0023] 2.3 Improved precision in knob operation:

[0024] The stepper motor is used to rotate the knob. Compared with the traditional manual rotary knob, it can achieve high-precision control for adjusting both image parameters and special effects parameters. It can meet the needs of fine adjustment of image effects during live broadcast, ensuring that the image presentation always meets the requirements of live broadcast, and avoiding poor image quality or unsatisfactory special effects due to inaccurate knob adjustment.

[0025] 3. Effectively enhances the human-computer interaction experience and improves ease of operation.

[0026] This intelligent live streaming switcher is equipped with a voice synthesis module, which is a significant upgrade to traditional visual effects switchers in terms of human-computer interaction. After any operation is completed, the voice synthesis module will promptly provide voice feedback to the operator, such as "Visual effects have been successfully switched" or "Screen brightness has been adjusted." Operators can intuitively and quickly understand the operation results without having to rely on visual observation or other complex methods to confirm whether the operation has taken effect. This allows them to quickly and accurately adjust their operations based on the feedback information. This instant voice feedback mechanism makes the live streaming operation process more intuitive and convenient, enhances the interactivity and communication efficiency between people and devices, and allows operators to more easily control various changes in the live streaming screen, thus improving the overall operating experience.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Reference Figure 1-5 A live streaming intelligent switching device includes a visual effects switcher 1. An electrical control box 2 is installed above the visual effects switcher 1. The electrical control box 2 contains a power module 6, a programmable logic controller 7, a motor driver 8, a voice recognition module 9, and a voice synthesis module 10. Several first electric telescopic rods 11, second electric telescopic rods 15, and stepper motors 13 are fixedly installed on the bottom surface of the electrical control box 2. The power module 6 provides power to the entire device, and the programmable logic controller 7 serves as the core control unit.

[0036] Reference Figure 2 and Figure 3 The bottom surface of the electrical control box 2 is vertically connected to several first electric telescopic rods 11 for automatically pressing the buttons on the screen effects switcher 1, second electric telescopic rods 15 for automatically pushing and pulling the push rods on the screen effects switcher 1, and stepper motors 13 for automatically rotating the knobs on the screen effects switcher 1. The first electric telescopic rods 11, stepper motors 13, and second electric telescopic rods 15 are all connected to the power module 6 and the programmable logic controller 7 through wires to form a complete electrical control circuit.

[0037] Specifically, the power module 6 supplies power to the first electric telescopic rod 11, the second electric telescopic rod 15, the stepper motor 13, and the programmable logic controller 7 via appropriate power lines. The programmable logic controller 7 is connected to the first electric telescopic rod 11, the second electric telescopic rod 15, and the stepper motor 13 via control signal lines in order to send control commands to them and realize the corresponding action operations.

[0038] Reference Figure 3 and Figure 5The cylinder body and the control box 2 in the first electric telescopic rod 11 are fixedly connected to ensure that the installation is stable. The protruding end of the first electric telescopic rod 11 is provided with a rubber sleeve 12. The rubber sleeve 12 has a dual function. On the one hand, it can reduce the impact force of the protruding end of the first electric telescopic rod 11 on the buttons on the screen effects switcher 1, and play a buffer protection role. On the other hand, a pressure sensor 20 is provided inside the rubber sleeve 12, and the upper surface of the pressure sensor 20 is fixedly connected to the protruding end of the first electric telescopic rod 11.

[0039] When the first electric telescopic rod 11 extends to press the button, the pressure sensor 20 can sense the force of the extended end pressing the button in real time and feed this pressure signal back to the programmable logic controller 7. For example, during a live broadcast, if a specific screen switching button needs to be pressed, without the feedback from the pressure sensor 20, the pressure at the extended end of the first electric telescopic rod 11 may be too high due to improper control, damaging the button. However, with the feedback from the pressure sensor 20, the programmable logic controller 7 can promptly judge and adjust the extension force of the first electric telescopic rod 11 to avoid this situation and ensure the safety and accuracy of button operation.

[0040] Reference Figure 3 The cylinder in the second electric telescopic rod 15 is also fixedly connected to the control box 2. Its extended end is fixedly connected to the connecting seat 16. The lower part of the connecting seat 16 is provided with a slot 17 for fitting the push rod on the screen effects switcher 1. This can ensure that the connection between the second electric telescopic rod 15 and the push rod is firm and can effectively transmit power. A linear displacement sensor 18 is arranged parallel above the second electric telescopic rod 15. The two ends of the linear displacement sensor 18 are fixedly connected to the cylinder in the second electric telescopic rod 15 and the connecting seat 16, respectively.

[0041] In actual operation, when it is necessary to perform automated linear movement of the push rod on the visual effects switcher 1, such as when implementing fade-in and fade-out visual effects, the push rod needs to be pushed to control the transition effect of the visuals. The programmable logic controller 7 controls the extension and retraction of the second electric telescopic rod 15, while the linear displacement sensor 18 monitors the displacement of the extended end in real time and feeds the displacement signal back to the programmable logic controller 7. The programmable logic controller 7 accurately controls the extension and retraction length of the second electric telescopic rod 15 according to the feedback signal, thereby realizing the precise linear movement of the push rod and achieving the purpose of accurately controlling the visual effects of the transition.

[0042] Reference Figure 3 and Figure 4 The housing of the stepper motor 13 is fixedly connected to the control box 2 to ensure its installation stability. The output end of the rotor in the stepper motor 13 is coaxially connected to a sleeve 14. A positioning groove 19 for fitting and connecting the knob on the screen effects switcher 1 is provided below the sleeve 14.

[0043] During a live stream, if parameters such as brightness, contrast, and color saturation of the image need to be adjusted, or the speed of visual effects needs to be adjusted, the programmable logic controller 7 will control the stepper motor 13 to rotate precisely by a certain angle. This rotation is then achieved by the sleeve 14, which drives the knob to rotate by the corresponding angle. Since the stepper motor 13 itself can precisely control the rotation angle, it can achieve precise rotation of the knob, thereby precisely adjusting the corresponding image parameters or visual effects parameters.

[0044] refer to Figure 1 and Figure 2 A touchscreen 4 is fixedly installed on the top of the control box 2. Through the touchscreen 4, operators can easily make various settings, such as setting the scene mode of automated operation, viewing the data fed back by various sensors, and manually fine-tuning the operating parameters of various electric components. At the same time, a motor driver 8, a voice recognition module 9, and a voice synthesis module 10 are fixedly installed inside the control box 2. The motor driver 8 is used to receive instructions from the programmable logic controller 7 and convert them into appropriate drive signals to drive the stepper motor 13, the first electric telescopic rod 11, the second electric telescopic rod 15, and other motor components to work normally. The voice recognition module 9 is used to receive external voice commands. For example, operators can say commands such as "switch to the next scene effect" or "brighten the screen." The voice recognition module 9 converts the voice signal into a text command and sends it to the programmable logic controller 7. The programmable logic controller 7 then controls the corresponding components to perform the operation according to the command. The voice synthesis module 10 is used to provide feedback to the operator on the operation results and other voice information. For example, after completing an operation, the voice synthesis module 10 will issue a voice prompt such as "the scene effect has been successfully switched," enhancing the human-computer interaction experience.

[0045] refer to Figure 1 and Figure 2 The visual effects switcher 1 has four corner rods 5 vertically installed at its lower corners. The four corner rods 5 are respectively fitted into the outer edges of the four corners of the visual effects switcher 1. The corner rods 5 serve to support and fix the visual effects switcher 1, ensuring that its position is stable during automated operation and that there is no shaking or other issues that would affect the accuracy of operation. In addition, the left and right side walls of the electrical control box 2 are provided with several corresponding heat dissipation holes 3. The heat dissipation holes 3 can timely dissipate the heat generated by the electrical components inside the electrical control box 2 during operation, ensuring that each component works stably in a suitable temperature environment, extending its service life, and improving the reliability of the entire device.

[0046] In large-scale live streaming events, it is often necessary to frequently switch between various visual effects and different video sources within a short period of time, while ensuring the accuracy and smoothness of the switching. For example, in the promotional segment of an e-commerce live stream, it is necessary to quickly switch between close-up shots of products, promotional information, and the host's explanations, while also using appropriate special effects, such as fade-in / fade-out and screen rotation, to enhance the visual appeal and attract viewers. If a traditional manual visual effects switcher is used, operators may make mistakes due to nervousness or slow operation, resulting in untimely screen switching or improper use of special effects. However, with this intelligent live streaming switcher, operators can pre-set operation commands for various trigger scenarios via the touchscreen 4, such as setting the screen switching order and adjusting special effect parameters for the "product display" scenario, and can also directly control the device via voice commands during the live stream.

[0047] For example, when the host gives the voice command "Show close-up of the product and add a fade-in effect", the voice recognition module 9 recognizes the command and transmits it to the programmable logic controller 7. The programmable logic controller 7 controls the first electric telescopic rod 11 to press the corresponding screen switching button, and at the same time controls the second electric telescopic rod 15 to push the push rod to realize the fade-in effect. The whole process is fast, accurate and highly automated, which greatly improves the efficiency and quality of live screen switching and special effects processing, and brings a better viewing experience to the audience.

[0048] In summary, this intelligent live streaming switching device effectively solves many problems associated with the manual operation of traditional visual effects switchers by using automated voice control and automated operation control triggered by various scenarios, combined with the coordinated operation of key components. It has good application prospects and practical value in the live streaming field.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
