Abstract
The utility model discloses a demonstration device for the order of strokes of a Chinese character, belonging to the teaching aid for Chinese demonstration. The demonstration device comprises a demonstration board, a hand-written input device and a controller placed at the back side of the demonstration board. 256 light emitting diodes (LEDs) are arranged at the front side of the demonstration board, and are arranged in a square matrix shape; and the controller comprises a first microprocessor module, a second microprocessor module, a third microprocessor module and a data storage unit. The demonstration device can visually demonstrate the order of strokes of the Chinese character, thereby alleviating teaching load of teachers.
Description
Technical field
The utility model relates to a kind of Chinese-character order of strokes apparatus for demonstrating, belongs to the Chinese language demonstration teaching aid.
Background technology
Chinese-character order of strokes is the emphasis of primary grades language teaching, and teacher, is normally write on blackboard by chalk during Chinese-character order of strokes in religion, and the stroke order while allowing the student remember that teacher writes.Yet this form of teaching is more uninteresting, the student is difficult to mention interest and is learnt.
The utility model content
The utility model, for the problem in background technology, proposes a kind of comparatively interesting Chinese-character order of strokes apparatus for demonstrating, and this device can be demonstrated out the stroke order of Chinese-character writing intuitively.
The utility model, for overcoming the above problems, adopts following technical scheme:
A kind of Chinese-character order of strokes apparatus for demonstrating, comprise demonstration board, hand input device and the controller that is positioned at the demonstration board back side; The front of described demonstration board is provided with 256 light emitting diodes; Described 256 light emitting diodes are the square matrices shape and arrange; Described controller comprises first microprocessor module, the second microprocessor module, the 3rd microprocessor module and data storage cell; Described 256 light emitting diodes are connected with the output terminal of controller respectively; Described first microprocessor module is by total line traffic control the second microprocessor module of I2C and the 3rd microprocessor module work; Described hand input device is connected by the usb data line with the first microprocessor module; Described data storage cell is connected with the first microprocessor module is two-way.
Preferably, described data storage cell is EEPROM.
Technique effect:
1, the utility model can be demonstrated out the stroke order of Chinese-character writing intuitively, has alleviated teacher's teaching load.
2, the utlity model has certain interest, can improve student's learning interest.
3, the utility model design is ingenious, easy to use, is adapted at each school and is promoted.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is first constitutional diagram of drawing while being lit of " Chinese " word.
Fig. 3 is circuit structure block diagram of the present utility model.
Label title in Fig. 1: 1, demonstration board; 2, controller; 3, light emitting diode; 4, hand input device.
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 demonstration board 1, hand input device 4 and the controller 2 that is positioned at demonstration board 1 back side; The front of described demonstration board 1 is provided with 256 light emitting diodes 3; Described 256 light emitting diodes 3 are the square matrices shape and arrange.
As shown in Figure 3, described controller 2 comprises first microprocessor module, the second microprocessor module, the 3rd microprocessor module and data storage cell to circuit structure of the present utility model; Described 256 light emitting diodes 3 are connected with the output terminal of controller 2 respectively; Described first microprocessor module is by total line traffic control the second microprocessor module of I2C and the 3rd microprocessor module work; Described hand input device 4 is connected by the usb data line with the first microprocessor module, for realizing character input function; Described data storage cell is connected with the first microprocessor module is two-way.
Described first microprocessor module, the second microprocessor module and the 3rd microprocessor module all adopt the MSP430F5438A microcontroller implementation of TI company, each microprocessor module has nearly 87 I/O mouths, is enough to meet the demand for control of 256 light emitting diodes; Described data storage cell is EEPROM, and it has the advantages that data are not lost after power down.
During use, teacher writes the Chinese character (as " Chinese " word) that needs demonstration to controller 2 by hand input device 4, controller 2 just can be controlled light emitting diode 3 first of " Chinese " word is drawn and first lighted (as shown in Figure 2), then, controller 2 is controlled light emitting diode 3 again the stroke of back is lighted in order one by one, finally forms complete " Chinese " word.
