Abstract
The utility model discloses a teaching demonstrator for binary numbers, belonging to teaching demonstrators. The demonstrator comprises a demonstration board and a controller positioned at the back side of the demonstration board, and a decimal number display unit, a binary number display unit, a plus-one button and a clearing button are arranged at the front side of the demonstration board, wherein the controller comprises a microprocessor module and a power supply. The teaching demonstrator for the binary numbers can help students better understand the difference between the binary numbers and the decimal numbers, thereby alleviating teaching burden of teachers.
Description
Technical field
The utility model relates to a kind of binary number education demonstrator, belongs to teaching demonstration device.
Background technology
Scale-of-two is a kind of numeral system extensively adopted in computing technique, and binary data is the number meaned with " 0 " and " 1 " two numbers, and its carry rules is " meet two advance one ".Binary number is also a Focal point and difficult point in basic computer teaching, and teacher need to tell about the difference between binary number and decimal number to the student on classroom.Yet only, by oral account, the student is difficult to understand content.
The utility model content
The utility model, for the problem in background technology, proposes a kind of binary number education demonstrator, to help the student, better understands the difference between binary number and decimal number.
The utility model, for overcoming the above problems, adopts following technical scheme:
A kind of binary number education demonstrator, the controller that comprises demonstration board and be positioned at the demonstration board back side; The front of described demonstration board is provided with tens digit display unit, binary digit display unit, adds a button and zero clearing button; Described controller comprises microprocessor module and power supply; The described button that adds all is connected with the signal input part of microprocessor module with the zero clearing button; Described tens digit display unit all is connected with the output terminal of microprocessor module with the binary digit display unit.
As further prioritization scheme of the present utility model, described tens digit display unit comprises three seven segment digital tubes; Described binary digit display unit comprises eight seven segment digital tubes.
As further prioritization scheme of the present utility model, No. 5 powered battery of two joints for described power acquisition.
Technique effect:
1, the utility model can help the student better to understand the difference between binary number and decimal number, has alleviated teacher's teaching load.
2, the utlity model has certain interest, can improve student's learning interest.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit structure block diagram of the present utility model.
Label title in Fig. 1: 1, demonstration board; 2, controller; 3, tens digit display unit; 4, binary digit display unit; 5, zero clearing button; 6, add a button.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is done in further detail and is introduced:
Structure of the present utility model as shown in Figure 1, the controller 2 that comprises demonstration board 1 and be positioned at demonstration board 1 back side; The front of described demonstration board 1 is provided with tens digit display unit 3, binary digit display unit 4, adds a button 6 and zero clearing button 5.
As shown in Figure 2, described controller 2 comprises microprocessor module and power supply to circuit structure of the present utility model; The described button 6 that adds all is connected with the signal input part of microprocessor module with zero clearing button 5; Described tens digit display unit 3 all is connected with the output terminal of microprocessor module with binary digit display unit 4.
Described tens digit display unit 3 comprises three seven segment digital tubes; Described binary digit display unit 4 comprises eight seven segment digital tubes; Described microprocessor module mainly is comprised of the MSP430F5438A microcontroller of TI company, and it has nearly 87 I/O mouths, can meet the demand for control of 11 seven segment digital tubes; No. 5 powered battery of two joints for described power acquisition.
During demonstration, at first by power connection, after powering on, microprocessor module carries out initialization, and by the whole zero clearings of numeral in tens digit display unit 3 and binary digit display unit 4.Teacher is often by once adding a button 6, and the numeral that microprocessor module can be controlled in tens digit display unit 3 and binary digit display unit 4 adds 1 simultaneously, and wherein: tens digit display unit 3 adopts the carry rules of " dot and carry "; Binary digit display unit 4 adopts the carry rules of " meet two advance ".In the ever-increasing process of numeral, the student can be clearly seen that binary number and decimal numeral difference.Be a teacher while pressing zero clearing button 5, microprocessor module can be by the whole zero clearings of numeral in tens digit display unit 3 and binary digit display unit 4.
