Description

Technical Field

[0001] This utility model relates to the field of teaching aids technology, and in particular to a teaching aid for demonstrating the process of converting between binary and decimal numbers. Background Technology

[0002] Binary is a base-2 number system used in mathematics and digital circuits. It's a binary number system that uses two different symbols, 0 and 1, to represent numbers. In digital electronic circuits, logic gates are implemented using binary directly. Modern computers and computer-dependent devices all use binary, with each number called a byte.

[0003] Binary data also uses position counting, and its position weights are powers of 2.

[0004] This counting method has been widely used in low-level computer logic operations, but it is not easy to understand, especially for children.

[0005] Top computer talents need to be cultivated from a young age, and the first lesson in computer training is learning binary. However, children find binary difficult to understand, and even some adults can learn it but cannot comprehend it, especially the relationship between binary and decimal, including the conversion steps. Currently, there are few devices to demonstrate this, and most teaching aids can only show the result after the transformation.

[0006] Based on this, this utility model designs a demonstration teaching aid for the binary to decimal conversion process to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a teaching aid that demonstrates the conversion process between binary and decimal numbers. This teaching aid facilitates the demonstration of binary-decimal conversion, making it easier for students to understand the changes between binary and decimal numbers and the principles behind these changes. It also helps students understand how decimal values ​​are broken down and then recombined into binary numbers. The entire process is fully demonstrated, the operation is simple, and the display is particularly clear. Even the entire demonstration step is fully shown in the same teaching aid, and the entire conversion process is synchronously and completely reflected, rather than just showing the change of a single number.

[0008] This utility model is implemented as follows: a demonstration and teaching aid for the binary to decimal conversion process, comprising:

[0009] Base plate, standard number plate, counting flip plate, and counting strip;

[0010] The base plate is a flat plate, and a handwriting pad is installed on the base plate;

[0011] The standard number plate is a horizontally placed long strip structure, and fixed values ​​are marked on the standard number plate;

[0012] Above the standard number board, multiple markers are also set, each of which corresponds to a fixed value on the standard number board.

[0013] Each of the marked numbers is marked with the same number, and each of the marked numbers corresponds one-to-one with the position of the numerical mark on the standard number plate;

[0014] The standard number plate and multiple marked numbers are all fixed on the base plate;

[0015] The counting flap is a flat plate, which can be flipped open and attached to the base plate. A counting flap is set above each of the marked numbers.

[0016] A patch is provided on the back of the counting flip plate, and each counting flip plate is covered with the corresponding mark by the patch;

[0017] The counting bar is a long strip structure, and there are multiple counting bars. Each counting bar is a long strip structure composed of multiple squares, and the number of squares in each different counting bar corresponds one-to-one with the value marked on the standard counting board.

[0018] Furthermore, the writing tablet is a whiteboard, and the writing tablet is attached to the base plate by a magnet.

[0019] Furthermore, the values ​​recorded on the standard number board are a power of 2 lookup table, and the values ​​on the standard number board increase sequentially from right to left, with each increase being a power of 2.

[0020] Furthermore, the counting bar is a magnetic bar, and the counting bar can be detached from the base plate by magnetic attraction.

[0021] Furthermore, the numbers marked on the counters are all 1, and each of the counting flip-up plates is marked with the number 0.

[0022] The beneficial effects of this utility model are: 1. This utility model adds a standard number board and a marked number for mutual comparison. The standard number board records decimal values. By splitting and combining the decimal values ​​of the standard number board with the counting bar, a one-to-one corresponding value is formed, thereby achieving the purpose of matching the standard number board with the counting bar. The marked number and the counting flip board work together to display binary numbers, thereby achieving the purpose of converting between binary and decimal.

[0023] 2. The standard number board and counting bar are both displayed on the base plate, and the marked number and counting flip are also displayed on the base plate at the same time. This allows binary, decimal, and total numbers to be displayed synchronously on the same base plate. Furthermore, whether the decimal value is used or not is synchronously displayed on the counting flip and marked number, making the device highly interconnected. Each conversion step is effectively displayed, and the conversion steps are clearly and completely displayed, which is more conducive to students' understanding of the conversion process.

[0031] Please see Figures 1 to 4 As shown, this utility model provides a demonstration teaching aid for the conversion process between binary and decimal. In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] In a specific embodiment of the technical solution of this utility model:

[0033] Includes base plate 1, standard number plate 2, counting flip plate 3, and counting bar 4;

[0034] The base plate 1 is a flat plate, or it can be a flexible magnetic board, which is easy to attach to the iron blackboard in the classroom. Currently, teaching blackboards or whiteboards are made of iron, which makes it easy to stick or attach teaching aids. The structure of this device is easy to use in teaching and can also be laid flat on the table, making it flexible and convenient to use.

[0035] A handwriting pad 11 is set on the base plate 1. The handwriting pad 11 is a blank board. The handwriting pad 11 is attached to the base plate 1 by magnets. After the value is written on the handwriting pad 11, the handwritten value can be erased. Different handwriting pads 11 can also be directly replaced. The magnetic attachment makes replacement convenient.

[0036] Standard number board 2 is a horizontally placed, elongated structure. It is marked with fixed values, and these values ​​are recorded in decimal. The values ​​recorded on standard number board 2 form a lookup table of powers of 2, and the values ​​on standard number board 2 increase sequentially from right to left by powers of 2. This conforms to binary conversion logic.

[0037] Above the standard number plate 2, there are also multiple marker numbers 21, which correspond one-to-one with each fixed value above the standard number plate 2.

[0038] Each number 21 is marked with the same number, and each number 21 corresponds one-to-one with the position of the numerical mark on the standard number board 2. This allows for a one-to-one comparison between the number 21 and the numerical value on the standard number board 2, forming a comparison table. By using the number 21, it is possible to know whether the corresponding numerical value on the standard number board 2 is used, thus achieving the purpose of marking. The operation is simple and counting is convenient.

[0039] The standard number plate 2 and multiple marked numbers 21 are fixed on the base plate 1;

[0040] The counting flap 3 is a flat plate. The counting flap 3 can be flipped open and attached to the base plate 1. A counting flap 3 is set above each of the marked numbers 21.

[0041] A patch 31 is provided on the back of the counting flip plate 3, and each counting flip plate 3 is pasted on the corresponding mark number 21 by the patch 31;

[0042] The number marked on the number 21 is 1, and the number 0 is marked on the front of each counting flip 3; or the markings can be reversed, that is, the counting flip 3 is marked with 1, and the number 21 is marked with 0, but it is necessary to ensure that the number marked on each number 21 is the same, and the number marked on the front of each counting flip 3 is also the same.

[0043] The counting bar 4 is a long strip structure and a magnetic bar. The counting bar 4 can be detached and magnetically attached to the base plate 1. This facilitates magnetic display and allows for the replacement of different technical bars 4 to adapt to the actual decimal values ​​being converted.

[0044] There are multiple counting bars 4, each of which is a long strip structure composed of multiple squares. The number of squares in each counting bar 4 corresponds to a marked value on one of the standard number boards 2. That is, there is a single counting bar 4 with 1 square, and there are also multiple individual counting bars 4 with different numbers of squares, such as 2, 4, 8, 16, 32, etc., to ensure that each marked value on the standard number board 2 corresponds to a counting bar 4 with the same number of squares.

[0045] It should be noted that:

[0046] This device does not merely display the conversion results between binary and decimal; instead, it breaks down a decimal value into a combination of count values ​​on counter bar 4. Values ​​used on standard number plate 2 are marked as 0 using counter flip plate 3, while unused values ​​are displayed as 1 using marker number 21. This clearly identifies which decimal value on standard number plate 2 has been used and displays it. The process of converting decimal to binary is demonstrated using standard number plate 2, counter flip plate 3, and marker number 21, and simultaneously displayed on base plate 1. The final marker number 21 and counter flip plate 3 form the final result of the binary conversion, while counter bar 4 represents the decimal value breakdown. The handwriting plate 11 records the decimal value to be converted. This device does not only display the result but also the entire conversion process from beginning to end, along with the conversion logic, all displayed clearly and completely on the same base plate 1, without omitting any conversion steps.

[0047] When using this utility model, such as Figure 4 The diagram illustrates the conversion of the decimal value 14 to binary. The number 14 is written on the writing pad 11 and displayed using the standard number pad 2. Since the numbers 2, 4, and 8 are used, the counting flip 3 can be flipped forward to display the number 1. Unused numbers cause the counting flip 3 to flip downwards, obscuring the mark 21, thus displaying the 0 on the front of the counting flip 3, forming a binary display. Used numbers are displayed as 1, and unused numbers as 0, thus forming binary. This clearly demonstrates the binary representation, while the writing pad 11 displays the decimal value.

[0048] Similarly, counting bar 4 is also displayed as a long strip composed of 2 squares, 4 squares, and 8 squares, attached to the base plate 1 for students to see. The decimal decomposition method is also clearly shown through counting bar 4. At the same time, the values ​​used are also fully displayed through the marker number 21 and the counting flip plate 3. All the numbers used in the conversion process are displayed on the base plate 1, and the decimal value decomposition logic is also displayed through counting bar 4. The logic of binary and decimal conversion is fully explained and demonstrated, making it easier for students to understand.

[0049] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
