Description

Technical Field

[0001] The present invention relates to the technical field of information transmission systems, and in particular to a multi-channel audio and video data visualized synchronous playback transmission system and method. Background Art

[0002] Synchronous transmission is a method of adding one or more synchronization characters SYN in front of a block of data. The SYN character is a synchronization control character selected from the ASCII code for communication. The data characters following the synchronization character do not need any additional bits. The synchronization character indicates the start of character transmission. The sender and the receiver should first agree on the number of synchronization characters. The bit grouping of synchronous transmission is much larger. It does not send each character independently, each with its own start bit and stop bit, but combines them and sends them together. We call these combinations data frames, or simply frames.

[0003] When audio and video data are played and transmitted synchronously, they are usually checked by real-time visual playback of the device before being uploaded. However, the displays of existing audio and video playback devices are fixed and easily damaged when the display screen is hit by an accident, causing cracks. In severe cases, the display frequency is completely broken, affecting the synchronous playback and inspection of audio and video. Moreover, the stability of the placed playback device is affected after being hit, and the playback device may fall down after the impact, which may easily cause secondary damage to the playback device.

[0018] S2: When the display is accidentally hit during use, the LCD screen pushes the U-shaped movable card holder to move, and the U-shaped movable card holder uses the movable connecting rod to push the rotating disk to deflect.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention proposes a multi-channel audio and video data visualization synchronous playback transmission system and method. After the equipment is placed, the audio and video data are collected by using a camera and a sound recorder, and the visualization inspection is carried out through synchronous playback on the display. When the display is accidentally hit during use, the liquid crystal display screen pushes the U-shaped movable card seat to move, and the U-shaped movable card seat uses a movable connecting rod to push the rotating disk to deflect. When the movable connecting rod deflects and moves, it pushes the top pressure rod to compress the first torsion spring and move. The U-shaped movable card seat moves in the U-shaped fixed card seat to unload the force. The movement of the liquid crystal display screen prevents it from being broken when hit. At the same time, the U-shaped movable card seat is pulled to move away from the U-shaped fixed card seat to disassemble and replace the liquid crystal display screen. The operation is convenient and quick.

[0024] 2. The present invention proposes a multi-channel audio and video data visualization synchronous playback transmission system and method. When the display is accidentally hit during use, the liquid crystal display screen pushes the U-shaped movable card seat to move, and the U-shaped movable card seat uses a movable connecting rod to push the rotating disk to deflect. When the movable connecting rod deflects and moves, it pushes the top pressure rod to compress the first torsion spring and move.

After the rotating disk rotates, the moving rod is pulled out of the L-shaped card plate by the connecting rope, and the telescopic spring rod is extended to push the deflection push rod to deflect. After the deflection push rod is deflected, the limit sleeve is pushed out of the installation slot port. The movable abutment plate in the limit sleeve extends obliquely to support the device casing obliquely. The stretching and extension support of the limit sleeve and the movable abutment plate is used to improve the placement stability of the device, thereby avoiding the problem of the device tipping over and falling after the display screen is hit.

[0025] 3. The present invention proposes a multi-channel audio and video data visualization synchronous playback and transmission system and method. After the data receiving and processing module inside the device casing receives the audio and video data, the AD conversion module performs signal conversion and transmits it to the MCU module. The MCU module receives and stores the data. The MCU module controls the audio and video coordination module to perform synchronous frame adjustment operations on the data and then puts it on the LCD screen for playback. After the LCD screen playback check is completed, the file size scanning module checks the file size. If the file is too large, it is compressed by the file compression module. Then the transmission signal self-check unit detects the three transmission signal strengths of the file output module, and selects the output line with high signal strength and stability for data transmission. Through the multi-channel data transmission setting of the file output module, the audio and video data can be uploaded flexibly and variably, avoiding the problem of being unable to transmit data after a single channel fails. It is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

In severe cases, the display screen is directly broken, affecting the synchronous playback of audio and video. Figure 1-Figure 2 and Figure 5-Figure 6 , provide the following preferred technical solutions:

[0039] The display 3 includes a U-shaped fixed card seat 31 fixedly connected to the inner wall of the port of the device casing 2 and a U-shaped movable card seat 32 movably engaged between the inner walls of the upper and lower ends of the U-shaped fixed card seat 31.

The liquid crystal display screen 33 is arranged corresponding to the port of the device casing 2. A connecting hole 34 is opened on the side wall of the U-shaped fixed card seat 31 corresponding to the liquid crystal display screen 33. A rotating disk 35 is movably arranged on the inner walls of the upper and lower ends of the device casing 2 adjacent to the U-shaped movable card seat 32 through a bracket. The rotating disk 35 is close to the inner wall of the upper and lower ends of the device casing 2. A movable connecting rod 36 is movably connected to the side wall near one end of the U-shaped movable card seat 32, and the end of the movable connecting rod 36 is movably connected to the outer wall at the upper and lower ends of the back plate of the U-shaped movable card seat 32, and a push rod 37 is movably connected to the outer wall of one side of the movable connecting rod 36, and the push rod 37 and the movable connecting rod 36 are connected by a first torsion spring 38. The end of the push rod 37 fits the back plate of the U-shaped movable card seat 32, and a buffer spring piece 39 is fixedly connected to the outer wall of the rotating disk 35 adjacent to the movable connecting rod 36, and the end of the buffer spring piece 39 fits the inner wall of the device casing 2.

[0040] When the buffer spring 39 ensures that it is in a normal relaxation state and fits against the inner wall of the device casing 2, the movable connecting rod 36 is arranged horizontally. At this time, the end of the movable connecting rod 36 fits against the intersection of the back plate of the U-shaped movable card seat 32 and the U-shaped fixed card seat 31. A protective film 331 is fitted on the outer wall of the LCD screen 33 on the side close to the connecting hole 34. When the LCD screen 33 is engaged in the U-shaped movable card seat 32, the protective film 331 is arranged against the inner wall of the U-shaped fixed card seat 31.

[0041] The support base 1 includes a support plate 101 and a positioning side plate 102 fixedly connected to both sides of the upper end of the support plate 101, an adjusting screw 103 is movably provided on the side wall of the positioning side plate 102, a limiting slide groove 104 is provided on the upper end of the support plate 101, and movable support members 105 are movably engaged on both sides of the limiting slide groove 104, and the top of the movable support member 105 extends to the outside of the port of the limiting slide groove 104, and its top is fixedly connected to a limiting ring 106, and the adjusting screw 103 on the inner side of the limiting ring 106 is inserted into the transfer hole 108 on the adjusting side plate 107, and the adjusting side plate 107 is movably arranged between the inner walls of the groove at both ends of the mounting plate 109, and the bottom of the connection between the adjusting side plate 107 and the mounting plate 109 is connected by a second torsion spring 1010.

[0042] Support rods 1011 are fixedly connected to both sides of the top of the mounting plate 109, and the support rods 1011 are fixedly connected to the bottom of the device housing 2. When the second torsion spring 1010 maintains a normal relaxation state, the mounting plate 109 is horizontally suspended adjacent to the top of the adjusting screw 103, and the end of the adjusting side plate 107 is arranged in contact with the side wall of the movable support member 105, and the threads on the outer walls at both ends of the adjusting screw 103 are reverse thread structures.

[0043] Specifically, after the equipment is placed, the camera 7 and the sound recorder 8 are used to collect audio and video data, and the data is played synchronously through the display 3 for visual inspection. When the display 3 is accidentally hit during use, the liquid crystal display screen 33 pushes the U-shaped movable card seat 32 to move, and the U-shaped movable card seat 32 uses the movable connecting rod 36 to push the rotating disk 35 to deflect. When the movable connecting rod 36 deflects and moves, it pushes the pressing rod 37 to compress the first torsion spring 38 and move. The U-shaped movable card seat 32 moves in the U-shaped fixed card seat 31 to unload the force, and the movement of the liquid crystal display screen 33 prevents it from being broken when hit. At the same time, the U-shaped movable card seat 32 is pulled to move away from the U-shaped fixed card seat 31 to disassemble and replace the liquid crystal display screen 33, and the operation is convenient and quick.

[0044] In order to further enhance the protection of the liquid crystal display screen 33, as Figure 2 and Figure 4 As shown, the following preferred technical solutions are provided:

[0045] The protective film 331 includes a first silicone film 3311 that is attached to the outer wall of the liquid crystal display screen 33, a sealing ring 3312 is fixedly connected to the edge of the first silicone film 3311, and a second silicone film 3313 is fixedly connected to the outer wall on the other side of the sealing ring 3312. The size of the second silicone film 3313 matches the size of the first silicone film 3311, and a vacuum layer 3314 is formed between the first silicone film 3311 and the second silicone film 3313. Hemispherical crystals 3315 are evenly arranged inside the edges of the first silicone film 3311 and the second silicone film 3313, and the arc surface of the hemispherical crystals 3315 is arranged away from the center of the silicone film.

[0046] Specifically, a vacuum layer 3314 is formed between the first silicone film 3311 and the second silicone film 3313 through the sealing ring 3312. After being attached to the outer wall of the liquid crystal display screen 33, the vacuum layer 3314 can perform anti-impact buffering. At the same time, the elasticity of the first silicone film 3311 and the second silicone film 3313 absorbs the impact in turn. The double-layer silicone film and the vacuum layer 3314 are used to effectively protect the liquid crystal display screen 33 from collision and explosion, thereby fully ensuring the protection of the liquid crystal display screen 33. At the same time, the curved surface of the hemispherical crystal 3315 inside the edge of the first silicone film 3311 and the second silicone film 3313 can reflect and diverge light, thereby reducing the lateral emission of light and preventing lateral peeping when visually inspecting audio and video data.

[0047] In order to solve the problem that the stability of the placed playback device is affected after being hit, and the playback device may fall down after being hit, please refer to Figure 2 and Figure 3 , provide the following preferred technical solutions:

The outer wall of the limit sleeve 22 is fixedly connected to the outer wall of the limit sleeve 22 adjacent to the lower end of the deflection push rod 25, and an L-shaped clamping plate 26 is fixedly connected to the inner wall of the mounting groove 21 adjacent to the lower end of the L-shaped clamping plate 26. A mounting cylinder 27 is fixedly connected to the inner wall of the mounting cylinder 27. A moving rod 28 is movably sleeved on the inner wall of the mounting cylinder 27. A connecting rope 29 is fixedly connected to the bottom of the moving rod 28. The end of the connecting rope 29 extends through the inside of the equipment casing 2, and its end is fixedly connected to the outer wall of the rotating disk 35.

[0049] The top end of the moving rod 28 is engaged with the end of the L-shaped clamping plate 26, and the lower end of the moving rod 28 extends to the bottom of the mounting tube 27 and is connected to the connecting rope 29. After the elastic component on the upper end of the bottom plate of the mounting tube 27 is wrapped around the outer wall of the moving rod 28, its top is fixedly connected to the bottom of the limit block on the outer wall of the moving rod 28. At this time, the moving rod 28 and the elastic component are in a normal relaxed state, and the moving stop plate 23 is retracted into the limit sleeve 22 and is engaged and received at the end of the mounting groove 21.

[0050] Specifically, when the display 3 is accidentally hit during use, the liquid crystal display screen 33 pushes the U-shaped movable holder 32 to move, and the U-shaped movable holder 32 uses the movable connecting rod 36 to push the rotating disk 35 to deflect. When the movable connecting rod 36 deflects and moves, it pushes the pressing rod 37 to compress the first torsion spring 38 and move. The U-shaped movable holder 32 moves in the U-shaped fixed holder 31 to unload the force. After the rotating disk 35 rotates, the connecting rope 29 is used to pull the movable rod 28 out of the L-shaped card plate 26, and the telescopic spring rod 24 is extended to push the deflection push rod 25 to deflect. After the deflection push rod 25 is deflected, the limit sleeve 22 is pushed out of the port of the installation slot 21, and the movable abutment plate 23 in the limit sleeve 22 extends obliquely to support the device housing 2 obliquely. The stretching and extension support of the limit sleeve 22 and the movable abutment plate 23 is used to improve the placement stability of the device, thereby avoiding the problem of the device tipping over and falling after the display screen is hit.

The output port 962 is electrically connected to the porous transmission connector 6 and then connected to the data receiving device using a wire for data transmission. The file output module 96 is also provided with an IC contact transmission module 963 for IC bonding induction contact transmission of data and a transmission signal self-test unit 964 for detecting the signal strength of the transmission line. The IC contact transmission module 963 is electrically connected to the IC reading transmitter 5.

[0054] Specifically, after the data receiving and processing module 92 inside the device housing 2 receives the audio and video data, the AD conversion module 93 performs signal conversion and transmits it to the MCU module 91. The MCU module 91 receives and stores the data. The MCU module 91 controls the audio and video coordination module 97 to perform synchronous frame adjustment operations on the data and then puts it on the LCD screen 33 for playback. After the playback check on the LCD screen 33 is completed, the file size scanning module 94 checks the file size. If the file is too large, it is compressed by the file compression module 95. Then, the transmission signal self-check unit 964 detects the three transmission signal strengths of the file output module 96, and selects an output line with high signal strength and stability for data transmission. Through the multi-channel data transmission setting of the file output module 96, audio and video data can be uploaded flexibly and variably, avoiding the problem of being unable to transmit data after a single channel fails, which is convenient and practical.

[0055] In order to better demonstrate the multi-channel audio and video data visualization synchronous playback transmission system, this embodiment provides a method for using the multi-channel audio and video data visualization synchronous playback transmission system, including the following steps:

[0056] Step 1: After the equipment is placed, use the camera 7 and the sound recorder 8 to collect audio and video data, and play them synchronously through the display 3 for visual inspection;

[0057] Step 2: When the display 3 is accidentally hit during use, the liquid crystal display screen 33 pushes the U-shaped movable card seat 32 to move, and the U-shaped movable card seat 32 uses the movable connecting rod 36 to push the rotating disk 35 to deflect. When the movable connecting rod 36 deflects and moves, it pushes the pressing rod 37 to compress the first torsion spring 38 and move, and the U-shaped movable card seat 32 moves in the U-shaped fixed card seat 31 to unload the force;

[0058] Step 3: After the rotating disk 35 rotates, the connecting rope 29 is used to pull the moving rod 28 away from the L-shaped clamping plate 26, and the telescopic spring rod 24 is extended to push the deflection push rod 25 to deflect. After the deflection push rod 25 is deflected, the limit sleeve 22 is pushed out of the port of the installation slot 21, and the moving abutment plate 23 in the limit sleeve 22 extends obliquely to support the device housing 2 obliquely;

[0059] Step 4: After the data receiving and processing module 92 inside the device housing 2 receives the audio and video data, the AD conversion module 93 performs signal conversion and transmits it to the MCU module 91. The MCU module 91 controls the audio and video coordination module 97 to perform synchronous frame adjustment operations on the audio and video data and then puts it on the LCD screen 33 for playback;

[0060] Step 5: After the LCD screen 33 plays and checks, the file size scanning module 94 checks the file size. If the file is too large, it is compressed by the file compression module 95. Then the transmission signal self-check unit 964 detects the three transmission signal strengths of the file output module 96 and selects an output line with high and stable signal strength for data transmission.
