Description

Technical Field

[0001] The utility model relates to the technical field of teaching aids, and more specifically, to a binary converter teaching aid. Background Art

[0002] With the development of the counting method, binary is a number system with a base of 2 in mathematics and digital circuits, representing a binary system with a base of 2. In this system, usually two different symbols 0 (representing zero) and 1 (representing one) are used to represent. The discoverer is Leibniz. In digital electronic circuits, the implementation of logic gates directly applies binary, and binary is used in modern computers and computer-dependent devices. Each digit is called a bit. When converting a decimal number to a binary number, the integer part and the decimal part need to be converted separately and then combined together. Therefore, the conversion process between conventional binary and decimal is relatively complex, lacking an intuitive means to link the conversion between decimal and binary, and the teaching difficulty is relatively high.

[0003] Therefore, it has become an urgent problem to be solved how to simplify the calculation process of the conversion between binary and decimal for easier teaching. Summary of the Utility Model

Through the movement of the display panel, different characters on the display area are displayed in the second opening and the third opening. The numerical range that can be displayed in the second opening and the numerical range in the third opening are defined. At this time, only by determining the decimal value in the second opening, the corresponding binary value in the third opening can be read. Similarly, only by determining the binary value in the third opening, the corresponding decimal value in the second opening can be known. The conversion between binary and decimal values is relatively simple, and at the same time, it is convenient to intuitively display the conversion between binary values and decimal values in teaching.

[0032] Embodiment 1:

[0033] See Figures 1 to 4 , this embodiment provides a binary converter teaching aid 1, including: a teaching aid body 10, the teaching aid body 10 is preferably made of a hard plastic material or a cardboard material, and the material selected according to different teaching purposes is different. The surface of the teaching aid body 10 is provided with a first opening 11, a second opening 12 and a third opening 13. The second opening 12 and the third opening 13 are located on the same side and arranged in parallel. The first opening 11 and the second opening 12, the third opening 13 are located on adjacent faces, and the second opening 12 and the third opening 13 communicate with the first opening 11; a display panel 20, the display panel 20 is connected to the first opening 11. Among them, the display panel 20 includes a display area 21, and a part of the display area 21 of the display panel 20 can move within the first opening 11. Characters are recorded in the display area 21, and the display panel 20 is moved so that different characters are displayed through the second opening 12 and the third opening 13.

[0034] Further, the first opening 11, the second opening 12, and the third opening 13 are recorded as a group. The teaching aid body 10 is provided with multiple groups of first openings 11, second openings 12, and third openings 13 arranged in parallel. There are multiple display panels 20, and the number of groups corresponds to the number of display panels 20. Among them, the characters in multiple groups of second openings 12 are added to obtain a decimal character, and the characters in multiple groups of third openings 13 are read out in sequence to be the binary character corresponding to the decimal character.

[0035] Among them, the display area 21 includes: a first display area 23, a second display area 24, a third display area 25, and a fourth display area 26. The first display area 23, the second display area 24, the third display area 25, and the fourth display area 26 are arranged in sequence. Both the first display area 23 and the third display area 25 are marked with the character zero. The second display area 24 is sandwiched between the first display area 23 and the third display area 25, and the second display area 24 is marked with the power of two. The fourth display area 26 is marked with the character one. Among them, the first display area 23 and the second display area 24 are alternately displayed through the second opening 12, and the third display area 25 and the fourth display area 26 are alternately displayed through the third opening 13. When the first display area 23 is displayed through the second opening 12, at this time, the corresponding third display area 25 is displayed through the third opening 13. When the second display area 24 is displayed through the second opening 12, at this time, the corresponding fourth display area 26 is displayed through the third opening 13.

[0036] The areas of the second opening 12 and the third opening 13 are the same, the areas of the first display area 23, the second display area 24, the third display area 25, and the fourth display area 26 are the same, and the second opening 12 is the same size as the first display area 23.

[0037] Along the extension direction of the first opening 11, the extension length of the display area 21 is adapted to the extension length of the first opening 11, and the clamping distance between the second opening 12 and the third opening 13 is the same as the distance from the first display area 23 to the third display area 25.

[0038] The display panel 20 further includes: a handle end 22. The handle end 22 is arranged at the position of adjacent display areas 21, and the handle end 22 always extends out of the first opening 11.

[0039] The first opening 11 is vertically aligned with the second opening 12 and the third opening 13. In this embodiment, the display panel 20 is specifically a kind of cardboard or hard plastic structure. At the same time, the thickness and width of the first opening 11 match the thickness and width of the display panel 20, so as to limit the inserted display panel 20 through the first opening 11 and prevent the display panel 20 from shaking too much left and right or up and down after being inserted into the first opening 11. Among them, the handle end 22 is the extension of the display area 21, and no characters are recorded on the handle end 22. The handle end 22 is used for the user to manually pull the display panel 20 to move. When the user holds the handle end 22 and pulls it, the sliding operation of the display panel 20 located in the first opening 11 can be realized, so that different characters on the display area 21 are displayed through the second opening 12 and the third opening 13.

[0040] The first opening 11 is a kind of hollow groove structure. Similarly, in this embodiment, the second opening 12 is also a kind of hollow groove structure, and the third opening 13 is also a kind of hollow groove structure. Comparing Figure 1 with Figure 4 it can be obtained that the first opening 11, the second opening 12 and the third opening 13 opened on the teaching aid body 10 are all unperforated one-way opening structures, that is, the display panel 20 can only be inserted into the teaching aid body 10 from the one-way opening of the first opening 11. The unopened area on the other side of the first opening 11 is used to abut against the display panel 20 to prevent the display panel 20 from being too deep in the first opening 11. The second opening 12 and the third opening 13 can only provide one-way display on the teaching aid body 10, which is convenient for the teaching aid users to distinguish the front and back of the teaching aid.

[0041] Among them, in this embodiment, since there are multiple display panels 20, correspondingly, there are also multiple groups of the first opening 11, the second opening 12 and the third opening 13 on the teaching aid body 10. One group of the first opening 11, the second opening 12 and the third opening 13 corresponds to one display panel 20. Multiple display panels 20 are arranged in sequence in the teaching aid body 10. Among them, taking Figure 2 and Figure 3 as an example, when reading the binary reading from left to right, reading the values in the third opening 13 in sequence can represent the binary value corresponding to the addition of the values in the second opening 12.

[0042] Among them, since there are multiple display panels 20 in this embodiment, therefore, in this embodiment, the first display panel 20 refers to Figure 2 and Figure 3The first one on the far right. From right to left, they are the first display panel 20, the second display panel 20, up to the Nth display panel 20. Among them, the character in the second display area 24 on the first display panel 20 is 2 to the power of zero, the character in the second display area 24 on the second display panel 20 is 2 to the power of one, and so on. The character in the second display area 24 on the Nth display panel 20 is 2 to the power of N - 1.

[0043] Furthermore, in this embodiment, preferably, there are 8 groups of first openings 11, second openings 12, and third openings 13. Correspondingly, there are also 8 display panels 20. In the display panel 20, all the characters displayed in the first display area 23 are 0, the characters displayed in the second display area 24 are decimal characters, and the characters displayed in the third display area 25 and the fourth display area 26 are the corresponding binary characters 0 and 1. By pulling the display panel 20 at the handle end 22, different characters are displayed in the second opening 12 and the third opening 13. Among them, the second opening 12 only allows the characters in the first display area 23 and the second display area 24 to be displayed, and the third opening 13 only allows the characters in the third display area 25 and the fourth display area 26 to be displayed, and there is a display relationship. For example, Figure 3 Taking it as an example, the rightmost display panel 20 is the first display panel 20. Classifying them from right to left in sequence, the decimal character displayed through the second opening 12 of the first group in the first display panel 20 is 1, the decimal character displayed through the second opening 12 of the second group in the second display panel 20 is 2, the decimal character displayed through the second opening 12 of the third group in the third display panel 20 is 4, the decimal character displayed through the second opening 12 of the fourth group in the fourth display panel 20 is 8, and so on, until the decimal character displayed through the second opening 12 of the eighth group in the eighth display panel 20 is 128. At this time, adding up the decimal characters in multiple second openings 12, the value 255 is obtained. At this time, reading the values in multiple third openings 13, the reading order is from left to right. Therefore, the binary value corresponding to the decimal value 255 is 11111111.

[0044] For the binary converter teaching aid 1 in this embodiment, by sliding the up and down position of the display panel 20, the decimal values displayed in the second opening 12 can be added up to obtain the required decimal value. At this time, reading the values from left to right in the third opening 13 is the binary value corresponding to the decimal value. The maximum number of bits supported by the binary in this embodiment is eight, that is, the conversion within the decimal value 255.

[0045] For example, when it is necessary to know the decimal value corresponding to the binary value 10101001, only the leftmost first display panel 20 needs to be moved, and the digit 1 in the leftmost first display panel 20 is displayed in the third opening 13. At this time, the number displayed in the corresponding second opening 12 is 128. Similarly, if the digit 0 in the second left display panel 20 is displayed in the third opening 13, the number displayed in the corresponding second opening 12 at this time is 0. And so on, the digits displayed in multiple third openings 13 are adjusted one by one to 10101001. At this time, the corresponding numbers displayed in multiple second openings 12 are: 128, 0, 32, 0, 8, 0, 0, 1. Adding up the decimal readings in multiple second openings 12 can obtain the decimal value corresponding to 10101001, which is 169.

[0046] For example, if it is known that the decimal value is 150 and it is necessary to convert the decimal value 150 into the corresponding binary value, only a certain calculation needs to be done at this time. Denote the leftmost third opening 13 as the first digit. Then, in sequence, the third openings 13 from left to right are denoted as the second digit, the third digit, the fourth digit, the fifth digit, the sixth digit, the seventh digit, and the eighth digit. Starting from determining the value displayed in the third opening 13 of the first digit, follow the principle: subtract 128, 64, 32, 16, 8, 4, 2, 1 from left to right respectively. If it can be subtracted, the corresponding position is set to 1; if it cannot be subtracted, the corresponding position is set to 0. Subtract until all are subtracted from left to right. Example:

[0047] First digit: 150 - 128 can be subtracted, and the position of the corresponding third opening 13 of the first digit is 1, and the result is 22;

[0048] Second digit: 22 - 64 cannot be subtracted, and the position of the corresponding third opening 13 of the second digit is 0, and the result is still 22;

[0049] Third digit: 22 - 32 cannot be subtracted, and the position of the corresponding third opening 13 of the third digit is 0, and the result is still 22;

[0050] Fourth digit: 22 - 16 can be subtracted, and the position of the corresponding third opening 13 of the fourth digit is 1, and the result is 6;

[0051] Fifth digit: 6 - 8 cannot be subtracted, and the position of the corresponding third opening 13 of the fifth digit is 0, and the result is still 6;

[0052] Sixth digit: 6 - 4 can be subtracted, and the position of the corresponding third opening 13 of the sixth digit is 1, and the result is 2;

[0053] Seventh digit: 2 - 2 can be subtracted, and the position of the corresponding third opening 13 of the seventh digit is 1, and the result is 0;

[0054] Eighth digit: 0 - 1 cannot be subtracted, and the position of the corresponding third opening 13 of the eighth digit is 0;

[0055] Furthermore, the binary number corresponding to the decimal number 150 is obtained as 10010110. Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
