Abstract
The utility model discloses a history event review device, and belongs to the field of ideological and moral teaching tools. The device comprises a rotating disk box, a years rotating disk, a stepping motor, a display element, a stepping motor drive circuit, a single-chip microcomputer control circuit and a voice module. The years rotating disk and the display unit are respectively arranged on the front surface of the rotating disk box. A pointer is further arranged at one side of the years rotating disk. A button is arranged on the side part of the rotating disk box. A rotating shaft of the stepping motor and a central shaft of the years rotating disk are connected. The history event review device is capable of helping students to review names, years and concrete content of significant events in history, thereby reducing the teaching burden of a teacher.
Description
Technical field
The utility model relates to a kind of historical events and reviews device, belongs to think of product teaching aid.
Background technology
Thinking on product class, teacher can tell about some major events on Chinese history to student, and requires student to remember the title of these events, the age of event generation and the particular content of event.In order to reach teaching purpose, teacher also can regularly help student to review, and allows student read aloud content.Yet this traditional review mode is comparatively uninteresting, cannot improve student's learning interest.
Utility model content
The utility model, for the problem in background technology, proposes a kind of historical events and reviews device, to improve student's learning interest, alleviates teacher's teaching load.
The utility model, for overcoming the above problems, adopts following technical scheme:
Historical events is reviewed a device, comprises rotating disk box, age rotating disk, stepper motor, display unit, stepper motor driving circuit, single chip machine controlling circuit and voice module; Described age rotating disk and display unit are all positioned at the front of rotating disk box; One side of described age rotating disk is also provided with a pointer; The sidepiece of described rotating disk box is provided with a button; The turning axle of described stepper motor is connected with the central shaft of age rotating disk; Described single chip machine controlling circuit is by stepper motor driving circuit control step machine operation; Described single chip machine controlling circuit is controlled display unit by signal wire and is worked; Described voice module is connected with single chip machine controlling circuit by serial port communication line; Described button is connected with the signal input part of single chip machine controlling circuit.
Preferably, described display unit adopts LED dot matrix screen.
Technique effect:
1, the utility model can help student to review the title of major event in history, the age of event generation and the particular content of event.
2, the utlity model has certain interest, can improve student's learning interest, alleviate teacher's teaching load.
3, the utility model design is ingenious, simple to operate, is convenient to promote.
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, rotating disk box; 2, age rotating disk; 3, stepper motor; 4, display unit; 5, pointer; 6, 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, comprises rotating disk box 1, age rotating disk 2, stepper motor 3, display unit 4, stepper motor driving circuit, single chip machine controlling circuit and voice module; Described age rotating disk 2 and display unit 4 are all positioned at the front of rotating disk box 1; One side of described age rotating disk 2 is also provided with a pointer 5; The sidepiece of described rotating disk box 1 is provided with a button 6; The turning axle of described stepper motor 3 is connected with the central shaft of age rotating disk 2, and when stepper motor 3 rotates, age rotating disk 2 also can be along with stepper motor 3 rotates together.
As shown in Figure 2, described single chip machine controlling circuit is by 3 work of stepper motor driving circuit control step motor for circuit structure of the present utility model; Described single chip machine controlling circuit is controlled display unit 4 work by signal wire, for showing the title of historical events; Described voice module is connected with single chip machine controlling circuit by serial port communication line, for realizing voice play function; Described button 6 is connected with the signal input part of single chip machine controlling circuit.
Described display unit 4 adopts LED dot matrix screen; The L298N doube bridge driver of the main YouST of described motor-drive circuit company forms; Described single chip machine controlling circuit is mainly that C8051F340 microprocessor and external circuit form by Silicon Labs company model.
During use, teacher only need press the button 6, single chip machine controlling circuit just can rotate certain step number by control step motor 3, when stepper motor 3 stops operating, pointer 5 can point to certain age (single-chip microcomputer can be calculated the age of pointer indication by the pedometer of electric machine rotation) on age rotating disk 2, now, teacher can allow the historical events that this of learner answering questions occurs in age, when learner answering questions does not go out, teacher only need press the button 6 again, and single chip machine controlling circuit just can be controlled display unit 4 historical events of this age generation is shown.Be a teacher and press the button for the third time at 6 o'clock, single chip machine controlling circuit can be controlled the particular content that voice module plays out this historical events, for student, reviews.
