Description

Technical Field

[0001] This utility model relates to the field of teaching aids technology, and in particular to an optical communication teaching demonstration device. Background Technology

[0002] Current textbooks include courses on optical fiber communication, explaining the principles of optical fiber guiding light and signal transmission. However, due to the lack of corresponding teaching demonstration devices, students find it difficult to personally experience the principles of optical fiber guiding light and optical communication.

[0003] A search revealed a Chinese patent application with patent number CN201822145041.6, which discloses a laser communication teaching demonstration device, including an analog signal demonstration module. The analog signal demonstration module includes an analog signal transmitting circuit for converting analog signals into optical signals and emitting them. However, the above technical solution does not have a corresponding mechanism to demonstrate the phenomenon of optical fiber transmitting light and corresponding image information, so it still has the problem of not being able to intuitively demonstrate the principle of optical fiber transmitting data and images. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an optical communication teaching demonstration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A demonstration device for optical communication teaching includes a demonstration board. A fixing sleeve is fixed to the outer wall of the demonstration board, and a first optical fiber is sleeved on the inner wall of the fixing sleeve. A slit is opened on one side of the outer wall of the demonstration board, and a hollow aluminum sheet is inserted into the inner wall of the slit. A green light source is provided on the outer wall of the demonstration board. A support ring is fixed to the outer wall of the demonstration board, and an integrated optical fiber bundle is fixed to the inner wall of the support ring.

[0006] As a further improvement of this utility model, the outer wall of the demonstration board is provided with a 5V power bank, a 9V battery and a 12V battery pack.

[0007] As a further improvement of this utility model, a bracket is fixed to the outer wall of the demonstration board.

[0008] As a further improvement of this utility model: a mobile phone placement box is fixed to the outer wall of the demonstration board, and a mobile phone body is inserted into the inner wall of the mobile phone placement box.

[0009] As a further improvement of this utility model: an optical fiber audio cable is plugged into the audio jack on the outer wall of the mobile phone body, and one end of the optical fiber audio cable is connected to a white light source.

[0010] As a further improvement of this utility model: a set of paper clips is fixed to one side of the outer wall of the demonstration board.

[0011] As a further embodiment of this utility model: a solar panel and a set of miniature megaphones are fixed to one side of the outer wall of the demonstration board, a set of ambient lights are fixed to the outer wall of the demonstration board, and an ambient light control module, a power amplification module and an audio noise reduction module are fixed to the outer wall of the demonstration board. The ambient lights and the ambient light control module are electrically connected, and the solar panel is electrically connected to the audio noise reduction module, the power amplification module and the miniature megaphones in sequence.

[0012] As a further embodiment of this utility model: a camera, a network switch, a transmitting fiber optic transceiver, a receiving fiber optic transceiver, a hard disk recorder, and a display screen are respectively fixed on the outer wall of the demonstration board. The camera and the network switch are connected to the network switch via a network signal transmission line. The network switch is connected to the transmitting fiber optic transceiver via a network signal transmission line. The transmitting fiber optic transceiver is connected to the receiving fiber optic transceiver via a second optical fiber. The receiving fiber optic transceiver is connected to the hard disk recorder via a network signal transmission line. The hard disk recorder is connected to the display screen via an audio and video transmission line.

[0013] The beneficial effects of this utility model are as follows: 1. The image captured by the camera is converted into a binary digital image signal. The transmitting fiber optic transceiver transmits this binary digital image information to the receiving fiber optic transceiver through optical fiber. At this time, the receiving fiber optic transceiver converts the optical signal into an electrical signal, which is then transmitted to the central processing unit inside the hard disk recorder through the network signal transmission line for processing. Finally, the processed image can be displayed on the screen, thus completing the demonstration of the entire process of fiber optic image data transmission.

[0014] 2. Connect a white light source to the audio jack on the outer wall of a mobile phone via an optical fiber audio cable. Then play a song on the phone. Next, place a corresponding number of paper pieces between two paper clips to hold the paper pieces between the optical fiber and the solar panel. As more paper pieces are added between the clips, the intensity of the light reaching the surface of the solar panel through the optical fiber gradually decreases, the light signal received by the solar panel gradually weakens, and the sound emitted by the "bee megaphone" gradually weakens. Then, remove the paper pieces one by one from one side of the clips. The light signal received by the solar panel gradually strengthens, and the sound emitted by the "bee megaphone" gradually strengthens. This experiment demonstrates that optical fibers can transmit audio signals, and the strength of the audio signal is related to the intensity of light.

[0015] 3. The staff first inserts the perforated aluminum sheet into the slit, places the perforated letters on the aluminum sheet between the green light source and the integrated fiber bundle, and turns on the green light source. The shape of the letters can be clearly seen at the other end of the integrated fiber bundle, thus visually verifying and demonstrating that the optical fiber can transmit light itself.

Detailed Implementation

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0020] Example 1: An optical communication teaching demonstration device, such as Figure 1-3 As shown, the demonstration board 1 is provided with a fixing sleeve 16 fixed to its outer wall. A first optical fiber 15 is sleeved on the inner wall of the fixing sleeve 16. A slit 23 is opened on one side of the outer wall of the demonstration board 1. A hollow aluminum sheet 13 is inserted into the inner wall of the slit 23. A green light source 21 is provided on the outer wall of the demonstration board 1. A support ring 20 is fixed to the outer wall of the demonstration board 1. An integrated optical fiber bundle 19 is fixed to the inner wall of the support ring 20. The outer wall of the demonstration board 1 is equipped with a 5V power bank 5, a 9V battery 7, and a 12V battery pack 8.

[0021] The outer wall of the demonstration board 1 is fixed with a bracket 4.

[0022] The staff first inserted the perforated aluminum sheet 13 into the slit 23, placed the perforated letters on the perforated aluminum sheet 13 between the green light source 21 and the integrated fiber bundle 19, and turned on the green light source 21. The shape of the letters could be clearly seen at the other end of the integrated fiber bundle 19, thus intuitively verifying and explaining that the optical fiber can transmit light.

[0023] The outer wall of the demonstration board 1 is fixed with a mobile phone placement box 10, and the inner wall of the mobile phone placement box 10 is inserted with a mobile phone body 11. An optical fiber audio cable 22 is plugged into the audio jack on the outer wall of the mobile phone body 11, and one end of the optical fiber audio cable 22 is connected to a white light source 14. A set of paper clips 17 are fixed to one outer wall of the demonstration board 1; A solar panel 18 and a set of miniature megaphones 2 are fixed to one side of the outer wall of the demonstration board 1. A set of ambient lights 12 are fixed to the outer wall of the demonstration board 1. An ambient light control module 3, a power amplifier module 6 and an audio noise reduction module 9 are fixed to the outer wall of the demonstration board 1. The ambient light 12 and the ambient light control module 3 are electrically connected. The solar panel 18 is electrically connected to the audio noise reduction module 9, the power amplifier module 6 and the miniature megaphones 2 in sequence. First, the white light source 14 is connected to the audio jack on the outer wall of the mobile phone body 11 via the optical fiber audio cable 22. Then, a song is played on the mobile phone body 11. Next, a corresponding number of paper pieces are placed between two paper clips 17 and clamped, so that the paper pieces block the first optical fiber 15 and the solar panel 18. As the number of paper pieces between the paper clips 17 increases, the intensity of the light shining through the first optical fiber 15 onto the surface of the solar panel 18 gradually decreases, the light signal received by the solar panel 18 gradually weakens, and the sound emitted by the megaphone 2 gradually weakens. Then, the paper pieces are pulled out one by one from one side of the paper clips 17. The light signal received by the solar panel 18 gradually strengthens, and the sound emitted by the megaphone 2 gradually strengthens. Thus, the experiment demonstrates that optical fibers can transmit audio signals, and the strength of the audio signal is related to the strength of the light.

[0024] During this experiment, ambient light 12 will move in sync with the audio, increasing the fun and dynamism of the experiment and allowing students to experience the achievements of modern technological development through hands-on observation.

[0025] In this embodiment, the diameter of the first optical fiber 15 is 1 cm.

[0026] Working principle: The staff first inserts the hollow aluminum sheet 13 into the slit 23, places the hollow letters on the hollow aluminum sheet 13 between the green light source 21 and the integrated fiber bundle 19, turns on the green light source 21, and the shape of the letters can be clearly seen at the other end of the integrated fiber bundle 19, thus intuitively verifying and explaining that the optical fiber can transmit light.

[0027] A white light source 14 is connected to the audio jack on the outer wall of a mobile phone 11 via an optical fiber audio cable 22. A song is then played on the mobile phone 11. A corresponding number of paper pieces are then placed between two paper clips 17, which hold the paper pieces between the first optical fiber 15 and the solar panel 18. As more paper pieces are added between the clips 17, the intensity of the light reaching the surface of the solar panel 18 through the first optical fiber 15 gradually decreases, the light signal received by the solar panel 18 gradually weakens, and the sound emitted by the megaphone 2 gradually weakens. Then, the paper pieces are pulled out one by one from one side of the clips 17. The light signal received by the solar panel 18 gradually strengthens, and the sound emitted by the megaphone 2 gradually strengthens. This experiment demonstrates that optical fibers can transmit audio signals, and the strength of the audio signal is related to the strength of the light.

[0028] Example 2: An optical communication teaching demonstration device, such as Figure 4 As shown, the outer wall of the demonstration board 1 is respectively fixed with a camera 24, a network switch 25, a transmitting fiber optic transceiver 26, a receiving fiber optic transceiver 28, a hard disk recorder 27, and a display screen 29. The camera 24 and the network switch 25 are connected to the network switch 25 through a network signal transmission line. The network switch 25 is connected to the transmitting fiber optic transceiver 26 through a network signal transmission line. The transmitting fiber optic transceiver 26 is connected to the receiving fiber optic transceiver 28 through a second fiber optic cable 30. The receiving fiber optic transceiver 28 is connected to the hard disk recorder 27 through a network signal transmission line. The hard disk recorder 27 is connected to the display screen 29 through an audio and video transmission line. The image captured by camera 24 is projected onto the surface of the image sensor inside camera 24. The image sensor converts this optical image into an analog electrical signal. After being processed by an analog-to-digital converter (A / D converter), this analog electrical signal is converted into a binary digital image signal.

[0029] At this time, the transmitting fiber optic transceiver 26 transmits the binary digital signal of this image information to the receiving fiber optic transceiver 28 through the second fiber optic cable 30 connected between the transmitting fiber optic transceiver 26 and the receiving fiber optic transceiver 28. The receiving fiber optic transceiver 28 then converts the optical signal into an electrical signal, which is then transmitted to the central processing unit inside the hard disk recorder 27 through the network signal transmission line for processing. Finally, the processed image can be displayed on the display screen 29, thus completing the demonstration of the entire process of transmitting image data through the first fiber optic cable 15.

[0030] In this embodiment, the diameter of the second optical fiber 30 is 0.5 mm.
