[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-7 The utility model provides a technical solution: an intelligent teaching aid for visually displaying binary encoding and decoding, comprising a plug-in board mounting seat 1 for connecting a color LED light source, a light sensor mounting seat 2 for connecting a light sensor, a controller, and a display screen. A storage board 3 for controlling a through-hole of the light source is plugged into the plug-in board mounting seat 1. The storage board 3 is provided with a plurality of through-holes 31 for the light source to pass through. A light guide fiber is connected between the plug-in board mounting seat 1 and the light sensor mounting seat 2. The light sensor and the display screen are both electrically connected to the controller.

[0030] Both the plugboard mounting base 1 and the light sensor mounting base 2 are provided with mounting holes for fixing them on the modular host base.

[0031] The controller includes a single chip microcomputer, and the single chip microcomputer is respectively connected with a control button and a buzzer, and there are four control buttons. The light sensor is electrically connected to the single chip microcomputer.

[0032] This teaching has two working modes:

[0033] Operation mode: The default mode is operation mode when the device is turned on. When there is a downward green arrow on the left side of the screen, it means it is in operation mode. You can switch to configuration mode by pressing the first control button (green);

[0034] Configuration Mode:

[0035] 1. When there is a downward red arrow on the right side of the screen, it means it is in configuration mode;

[0036] 2. When in configuration mode, you can select the code book by the second control button (red) (the selected code book will be displayed in blue numbers on the screen);

[0037] 3. After configuration is complete, press the red control button again to switch to operation mode and save the selected codebook.

[0038] Optionally, there are 6 through holes 31 on the storage board 3, and LED light can pass through these holes. If the light passing through represents 1, the default storage of the analysis card is 111111;

[0039] By sticking black tape on some of the round holes, the stored content can be changed. For example, after sticking the first and third round holes, the stored content becomes 010111. According to the password table 0 designed for this product, it can be matched with the letter W. This realizes the visualization and editability of information storage, and all students can participate in it.

[0040] If the first four holes are covered, the binary content is 000011, and the letter corresponding to code book 0 is C;

[0041] Students can customize which round holes to stick on to store different contents on the board.

[0042] The principle is the same as that of CDs, except that CDs are more precise and can achieve a terabyte storage capacity on a single disc with the help of a pickup head and decoding program.

[0043] A slot 11 for inserting the memory board 3 is provided on the front of the plug-in board mounting seat 1, a light source inlet 12 for connecting a color LED light source is provided on one side of the plug-in board mounting seat 1, and a light source emitting port 13 is provided on the other side of the plug-in board mounting seat 1. The light source inlet 12 and the light source emitting port 13 are both connected to the slot 11, and the light source inlet 12, the light source emitting port 13 and the through hole 31 on the memory board 3 are coaxially arranged.

[0044] A light source receiving port 21 is provided on one side of the optical sensor mounting base 2 , and an optical sensor socket 22 for connecting an optical sensor is provided on the other side of the optical sensor mounting base 2 .

[0045] The principle of binary for optical communication:

[0046] When no storage card is inserted into the card slot, the six optical fibers transmit light to the right side. When a storage card with customized storage content is inserted into the left side, the signals of the different optical paths are cut off. That is, the binary sequence detected by the right optical sensor is consistent with the binary content stored on the left storage card, realizing the visualization of information transmission.

[0047] If we assume that the two ends of the optical fiber are several kilometers apart, then we can transmit data through optical signals.

[0048] The communication principles of optical fibers commonly used in real-world communication scenarios (such as home broadband) are basically similar to this, except that commercial optical fibers can provide longer transmission distances and greater network bandwidth.

[0049] When a memory card is inserted into the card slot, the binary sequence content on the memory card can be converted into sound, 1 is a long "beep", and 0 is two short "beeps" in succession;

[0050] In this teaching scenario, students can translate the content of the telegram they hear by using the telegram sound and the code table provided.

[0051] This principle is basically the same as that of the telegraph machine widely used during the Anti-Japanese War.

[0052] The difference is that the telegraph uses electromagnetic waves to carry signals, which has a longer transmission distance.

[0053] The optical sensor searches the corresponding password table based on the signals received from each optical fiber and finds the corresponding characters.

[0054] By encoding letters and numbers in dot matrix, a mapping relationship is formed between letters and numbers and LED lamp beads. The corresponding number of LED lamp beads are lit to realize the display of letters and numbers.

[0055] The binary password table is as follows:

[0056]

[0057] The color LED light source includes a light emitting diode LED1, a light emitting diode LED2, a light emitting diode LED3, a light emitting diode LED4, a light emitting diode LED5, and a light emitting diode LED6 which are connected to 12V and are arranged in parallel.

[0058] The light sensor includes a photoresistor module connected to 5V and arranged in parallel, the photoresistor module includes a photoresistor R1 and an adjustable resistor R2 connected in series, a photoresistor R3 and an adjustable resistor R4 connected in series, a photoresistor R5 and an adjustable resistor R6 connected in series, a photoresistor R7 and an adjustable resistor R8 connected in series, a photoresistor R9 and an adjustable resistor R10 connected in series, and a photoresistor R11 and an adjustable resistor R12 connected in series.

[0059] The single-chip microcomputer includes a chip U1, pin 1 of the chip U1 is connected to the wiring terminal of the photoresistor R1 and the adjustable resistor R2, pin 2 of the chip U1 is connected to the wiring terminal of the photoresistor R3 and the adjustable resistor R4, pin 4 of the chip U1 is connected to the wiring terminal of the photoresistor R5 and the adjustable resistor R6, pin 5 of the chip U1 is connected to the wiring terminal of the photoresistor R7 and the adjustable resistor R8, pin 6 of the chip U1 is connected to the wiring terminal of the photoresistor R9 and the adjustable resistor R10, and pin 7 of the chip U1 is connected to the wiring terminal of the photoresistor R11 and the adjustable resistor R12.

[0060] The control button is set to switch SW1 connected between pins 27 and 33 of chip U1, the buzzer is connected between pins 23 and 24 of chip U1, and the display is connected to pin 34 of chip U1.

[0061] When using the system, explain to students the composition and general working principle of the system. After students select a code book, they can encode the letters in advance with tape. Students operate it by hand, familiarize themselves with the operation method, feel the screen output and telegraph sound, cover the screen, and one student inputs a paragraph of English through the card board, and other students translate the telegram by listening to the telegraph sound and looking up the code table.

[0062] The present invention utilizes punched cards to store binary data, which can be cards or very long punched paper tapes. An LED light-emitting head and a light-guiding material with a light-transmitting surface and strong light at the end points are used to transmit and display binary information visually. The a and b technologies are combined. Light can pass through where there are holes, and light cannot pass through where there are blocked areas, thereby representing 1 and 0 respectively. Inserting a memory card into the card slot behind the LED light-emitting head naturally loads the binary data from the storage medium to the transmission channel. A photoresistor module is used to simultaneously sense and receive multi-bit binary information. Then, a coding table is looked up according to the binary data to perform mapping decoding. Finally, a dot matrix screen is used to display the decoded characters, while simulating the sound of a telegraph or the sound of other coding rules to output sound.

[0063] Through this device, when students first come into contact with binary-related technologies in information classes, they can combine code books and make code cards or paper tapes by hand, participate in the process of coding and information storage, and understand how light transmits information by observing the obstruction and visibility of the light path. They can then decode by listening to the sound combined with the code book, and check whether the results meet expectations through the dot matrix screen. The whole process is very intuitive and easy to understand, allowing students to understand the relevant underlying technologies in the fastest and most intuitive way.

[0064] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
