Description

Technical Field

[0001] The present invention relates to the field of exhibition services, and in particular to a multimedia annular bearing matching device and a driving and controlling method. Background Art

[0002] In exhibition halls of various historical, cultural, and technological expositions, dynamic and continuous displays of objects, people, and other elements are sometimes necessary. Modern exhibitions often use large screens to scroll through the displayed content. However, single large-screen scrolling has several drawbacks: First, large numbers of visitors crowd into the same large-screen area, reducing both the movement of people and the comfort of the surrounding environment. Second, the content displayed on a single large-screen scrolling display is single. For example, if the large screen has already started playing and has been playing for a while, some visitors may just arrive. As a result, these visitors may not have seen the video content from the beginning until their arrival, leaving them unable to understand the context of the video content being played on the large screen.

[0003] In summary, when playing videos at various exhibitions, how to make the surrounding environment (crowd density) of visitors better when watching the videos, while allowing visitors to watch the complete video content from beginning to end, becomes a problem that needs to be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multimedia annular bearing matching device and a driving control method, so that the surrounding (crowd density) environment of visitors when watching videos is better, and at the same time, visitors can watch the complete video content from beginning to end.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention provides a multimedia annular bearing assembly, comprising an inner annular frame, a gear ring frame positioned on the periphery of the inner annular frame, and a low-position outer cylinder frame positioned on the periphery of the gear ring frame. Multiple barcode mounting modules are evenly distributed on the inner annular frame, with barcodes containing corresponding information attached to the radially outward end faces of the barcode mounting modules. A steering mounting bracket is mounted in conjunction with the gear ring frame and the low-position outer cylinder frame. A video player is vertically fixedly mounted on the outer end of the steering mounting bracket, with an infrared probe positioned in the middle of the upper side of the video player. A barcode reader for reading the barcode information from the barcode mounting module is mounted in conjunction with the inner end of the bottom of the steering mounting bracket. A micro-servo motor is disposed on the bottom side of the steering mounting bracket, with a differential gear disposed on the output shaft of the micro-servo motor. A differential tooth opening is provided on the upper end face of the gear ring frame, and the differential gear meshes with the differential tooth opening. Multiple LED information signs are disposed on the side face of the outer ring of the low-position outer cylinder frame, wherein there is only one LED information sign disposed in the radial direction of any barcode mounting module.

[0007] A circle of outer protective fence is provided around the low outer cylinder frame, and the outer protective fence is located in the outer area of ​​the video player. A visitor activity area is formed around the outer protective fence. The visitor activity area is provided with a starting viewing area, and the starting viewing area is located in the radial direction of a barcode installation module.

[0008] As a preferred technical solution of the multimedia annular load-bearing device of the present invention, a steering mounting bracket has a steering slot defined on its bottom side, through which the steering mounting bracket engages with the upper end of the low-position outer cylinder frame. A roller structure is disposed at the top of the steering slot of the steering mounting bracket, which is in rolling contact with the upper end of the low-position outer cylinder frame.

[0009] As a preferred technical solution of the multimedia annular bearing matching device of the present invention: the inner ring surface of the upper end of the low-position outer cylinder frame is provided with a contact electrode, and the steering slot of the steering mounting bracket is equipped with a brush.

[0010] As a preferred technical solution of the multimedia annular bearing matching device of the present invention: a high-position outer cylinder frame is suspended above the low-position outer cylinder frame, and a surrounding gap is formed between the low-position outer cylinder frame and the high-position outer cylinder frame.

[0011] As a preferred technical solution of the multimedia annular bearing matching device of the present invention: the LED information board has a built-in LED light, and the surface of the LED information board is configured with information that matches the real-time playback content of the video player.

[0012] As an optimal technical solution for the multimedia ring-shaped carrying cooperation device of the present invention: the video player has a built-in storage module, and the storage module is provided with multiple video contents. After the barcode reader scans the barcode information of any barcode installation module, it independently drives the video player to play a corresponding video content.

[0013] The driving and controlling method of a multimedia annular bearing matching device of the present invention includes the following steps:

[0014] Step 1: Start viewing the video content: First, the first group of tourists arrive at the starting viewing area according to the instructions. The infrared sensor on the video player at the starting viewing area detects human movement, and the video player at the starting viewing area starts playing. At the same time, the micro-servo motor configured for the steering mounting bracket connected to the back of the video player at the starting viewing area starts, and the video player begins to move in a uniform circular motion. Secondly, if the infrared sensor on the video player that is moving in a uniform circular motion does not detect human movement, the video player stops moving, and the control system starts a countdown. When the countdown ends: if the infrared sensor on the video player detects human movement, the video player continues to move in a uniform circular motion; if the infrared sensor on the video player does not detect human movement, the video player turns off.

[0015] Step 2: Synchronous display of the LED information board: As the steering mounting bracket drives the video player to move in a uniform circular motion, each time the barcode reader on the inner side of the steering mounting bracket reads a new barcode information on a barcode mounting module, the video player starts playing the video content corresponding to the current barcode information. At the same time, the LED information board on the outer ring side of the low-position outer cylinder frame, located directly below the video player, is energized to illuminate the corresponding information on the LED information board.

[0016] Step 3: Displacement of adjacent video players: For any stationary video player, let the position of the upstream barcode installation module it passes by be [......, W n-2 , W n-1 , W n ], when the video player adjacent to the upstream side of the circular moving direction is moving in a uniform circular motion, the moving video player reaches position W n-1 When the barcode installation module position is reached, the stationary video player starts to move. If the video player adjacent to the upstream side of the originally stationary video player stops moving, the stationary video player becomes stationary again.

[0017] Step 4: Video Player Home Position: When the infrared sensors on all video players detect no human activity, the video player closest to the starting viewing area on the upstream side of the low-position outer cylinder mount directly opposite the starting viewing area rotates clockwise to a position directly opposite the starting viewing area. All video players rotate in a clockwise direction.

[0018] As a preferred technical solution of the multimedia annular bearing matching device driving and controlling method of the present invention: the shortest distance moved by the video player moving in a uniform circular motion starting from the starting viewing area is greater than the distance to the outer surface of the low-position outer cylinder frame blocked by the video player.

[0019] Compared with the existing technology, the beneficial effects of the present invention are:

[0020] The present invention designs an annular inner ring frame, configures multiple barcode installation modules on the gear ring frame, configures multiple steering installation brackets on the gear ring frame and the low-position outer cylinder frame, configures a video player on the outside of the steering installation bracket, and configures a barcode reader on the inside of the steering installation bracket. When tourists arrive at the tourist activity area, they quickly reach the starting viewing area, and the video player starts to move at a constant speed. After each barcode installation module is reached by the video player, the video player plays the corresponding content. Moreover, tourists who arrive later do not need to follow the previous tourists to watch the same video player. The later arriving tourists only need to go to the starting viewing area and start watching the video content following the video player in the starting viewing area. In this way, the density of the crowd of tourists watching the video content is greatly dispersed, so that the surrounding (crowd density) environment of the visiting tourists when watching the video is better, and the tourists can watch the complete video content from beginning to end.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Example 1: The present invention relates to a multimedia annular bearing matching device, the main structural features of which are as follows:

[0028] See also Figure 1 、 Figure 2 The device comprises an inner annular frame 1, a gear ring frame 3 positioned peripherally therefrom, and a lower outer cylinder frame 4 positioned peripherally therefrom. The inner annular frame 1 is evenly distributed with multiple barcode mounting modules 2, each with corresponding barcode information attached to its radially outer end face. The gear ring frame 3 and the lower outer cylinder frame 4 are equipped with a steering mounting bracket 6. A barcode reader 9 is located at the inner end of the bottom of the steering mounting bracket 6 for reading the barcode information on the barcode mounting modules 2.

[0029] There are multiple LED information boards 5 on the outer ring side of the low-position outer cylinder frame 4, and any barcode installation module 2 is only equipped with one LED information board 5 in the radial direction.

[0030] The low-position outer cylinder frame 4 is equipped with an outer protective fence 10, which is located in the outer area of ​​the video player 7. The outer protective fence forms a visitor activity area 11 around the perimeter of the outer protective fence, which is equipped with a starting viewing area 15. This starting viewing area 15 can be marked with a reminder sticker on the ground or a vertically downward-pointing LED indicator installed on the ceiling, allowing visitors to quickly find the starting point of the tour. Starting viewing area 15 is located radially from the location of the barcode mounting module 2.

[0031] See also Figure 2 、 Figure 3 The outer end of the steering mounting bracket 6 is vertically fixed on the video player 7, and the upper position of the video player 7 is equipped with an infrared probe 14. The infrared probe 14 detects whether there is human activity within a specific range of the video player 7. If someone is active, the video player 7 will be activated so that the screen starts playing. If no one is active, the video player 7 will be stopped and the screen will be turned off. The bottom of the steering mounting bracket 6 is equipped with a micro servo motor 8, and the output shaft of the micro servo motor 8 is equipped with a differential gear 801. The upper end face of the gear ring frame 3 is equipped with a differential tooth mouth 301, and the differential gear 801 and the differential tooth mouth 301 are engaged with each other for driving.

[0032] See also Figure 3, the bottom of the steering mounting bracket 6 is provided with a steering slot 601, and the steering mounting bracket 6 is clamped on the upper end of the lower outer cylinder frame 4 through the steering slot 601. The top of the steering slot 601 of the steering mounting bracket 6 is provided with a roller structure 602, and the roller structure 602 is in rolling contact with the upper end of the low-position outer cylinder frame 4. The inner ring surface of the upper end of the low-position outer cylinder frame 4 is provided with a contact electrode 604, and the steering clamping slot 601 of the steering mounting bracket 6 is provided with a brush 603. The contact electrode 604 is divided into a positive electrode and a negative electrode, and the contact electrode 604 is always charged. During the operation of the steering mounting bracket 6, the brush 603 continuously contacts the contact electrode 604 to provide power. Combined with Figure 2 , the operations of the micro servo motor 8, the video player 7 and the barcode reader 9 are continuously realized.

[0033] See also Figure 1 、 Figure 4 , the high outer cylinder frame 2 is suspended above the low outer cylinder frame 4. A surrounding gap 13 is formed between the low outer cylinder frame 4 and the high outer cylinder frame 2. The steering mounting bracket 6 moves around the surrounding gap 13 and performs a circular motion.

[0034] Embodiment 2: The present invention relates to a driving and controlling method for a multimedia ring-shaped carrying device, including four steps: starting to watch video content, synchronously displaying an LED information board 5, moving and advancing an adjacent video player 7, and returning the video player 7 to its original position. The specific steps are as follows:

[0035] 1. Video content viewing begins: The first group of visitors arrive at the starting viewing area 15 as instructed. The infrared sensor 14 on the video player at the starting viewing area 15 detects human movement, and the video player 7 at the starting viewing area 15 starts playing. Simultaneously, the micro-servo motor 8 configured for the steering mounting bracket 6 connected to the back of the video player 7 at the starting viewing area 15 is activated, and the video player 7 begins uniform circular motion. If the infrared sensor 14 on the uniformly circularly moving video player 7 fails to detect human movement, for example, if some visitors walk slowly and the video player 7 moves relatively quickly, and the visitors sometimes pause briefly to catch up, the video player 7 stops moving and the control system starts a countdown, for example, for 5 seconds. After the countdown ends: if the infrared sensor 14 on the video player 7 detects human movement, the video player 7 continues uniform circular motion; if the infrared sensor 14 on the video player 7 fails to detect human movement, the video player 7 turns off.

[0036] ㈡LED information board 5 synchronous display: When the steering mounting bracket 6 drives the video player 7 to move in a uniform circular motion, each time the barcode reader 9 located on the inner side of the steering mounting bracket 6 reads a new barcode information on the barcode mounting module 2, the video player 7 starts to play the video content corresponding to the current barcode information. At the same time, the LED information board 5 located directly below the video player 7 on the outer ring side of the low-position outer cylinder frame 4 is powered on to illuminate the corresponding information on the LED information board 5, such as the time, event, etc. on the LED information board 5. After the video player 7 leaves, the LED information board 5 is powered off and extinguished.

[0037] (3) Displacement of adjacent video player 7: For any stationary video player 7, let the position of the upstream barcode installation module 2 passed by it be [......, W n-2 , W n-1 , W n ], when the video player 7 adjacent to the upstream side of the circular moving direction is moving in a uniform circular motion, the moving video player 7 reaches position W n-1 When the barcode installation module 2 is located, the stationary video player 7 begins to move. If the video player 7 upstream of the previously stationary video player 7 stops moving, the stationary video player 7 becomes stationary again, moving at the same rate as the upstream adjacent video player 7. When a moving video player 7 moves downstream, a gap is left between the two video players 7 to prevent the downstream adjacent stationary video player 7 from obstructing the position it is about to move to, ensuring smooth movement of the moving video player 7 toward the downstream area.

[0038] (iv) Video Player 7 Initial Return: When the infrared sensors 14 on all video players 7 detect no human activity, the video player 7 on the upstream side of the lower outer cylinder frame 4, which is closest to the initial viewing area 15 and directly opposite the initial viewing area 15, rotates clockwise to a position directly opposite the initial viewing area 15. The circular movement direction of all video players 7 is clockwise.

[0039] Furthermore, the shortest distance traveled by the video player 7, which begins its uniform circular motion from the starting viewing area 15, is greater than the distance to the outer surface of the lower outer cylinder frame 4 obscured by the video player 7. This is also easy to understand: once the video player 7 is activated from the starting viewing area 15 and the infrared probe 14 stops detecting human activity, the video player 7 will continue to move for a certain distance, thus "freeing up" the initial position corresponding to the starting viewing area 15 for the later-arriving video player 7 to initially "reset" and occupy the initial position corresponding to the starting viewing area 15.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
