Abstract
The utility model discloses a wireless hand inputting and demonstrating device for language teaching, which belongs to the field of language teaching and comprises a stylus, a writing board and an electronic whiteboard. The wireless hand inputting and demonstrating device is characterized in that the writing board comprises a power supply, a pressure sensor, a modulus converter, a micro-processor and a wireless signal transmitting device. The pressure sensor converts collected pressure signals into electric signals and transmits the electric signals to the modulus converter to generate data signals, then the data signals enter into the micro-processor to be coded and are transmitted in the mode of wireless signals through a wireless signal transmitting device. The electronic whiteboard comprises a display screen, a central processor and a wireless signal receiving device. Wireless signals collected by the wireless signal receiving device enter into the central processor to be decoded and then are displayed on the display screen. Compared with the prior art, the wireless hand inputting and demonstrating device can realize wireless transmitting and displaying of handwritings without any computer host, thereby benefiting teachers to fully express teaching standard, being beneficial to improving teaching quality and saving cost.
Description
[technical field]
The utility model relates to a kind of teaching consuming energy subset, is used for the wireless handwriting input and the demonstration of language teaching.
[background technology]
Language teaching needs the teacher to carry out the statement analysis through regular meeting, and usually mode is on blackboard sentence to be write out, and utilizes to indicate the make pauses in reading unpunctuated ancient writings language of this grammer more complicated of analysis, especially Japanese Teaching of line.Propelling along with the teaching electronization, developed corresponding electronic teaching system at present, generally include handwriting pad, computing machine and electronic whiteboard or projector, utilize handwriting pad handwriting characters or icon line and be presented on the giant-screen, solved the disadvantage of Palingraphia, saved time and muscle power, but still there is following problem in this kind equipment: 1. must connect the hardware requirement height by computing machine; 2. handwriting pad position, main frame position, display screen position need the teacher to determine the position because of the wired connection relative fixed, cause operation inconvenience, and the teacher can not give full play to the teaching level, thereby influences quality of instruction.
[summary of the invention]
Technical assignment of the present utility model is at above the deficiencies in the prior art, and a kind of wireless handwriting input and apparatus for demonstrating that is used for language teaching is provided, and can carry out hand-written mark under the situation of divorced from computer.
The technical scheme in the invention for solving the technical problem is: comprise writing pencil, handwriting pad and electronic whiteboard, wherein said handwriting pad comprises power supply, pressure inductor, analog-to-digital conversion device, microprocessor, wireless signal transmitting device, pressure inductor transfers the pressure signal of gathering to electric signal and imports the analog-to-digital conversion device into, digital signal after the analog to digital conversion enters the microprocessor coding, launches in the wireless signal mode by wireless signal transmitting device; Described electronic whiteboard comprises display screen, center processor, wireless signal receiving trap, and the wireless signal that the wireless signal receiving trap collects enters center processor and decodes, and that continues is presented on the display screen.
Above-mentioned microprocessor is a single-chip microcomputer, and model is MK7A11P.
Above-mentioned center processor is a single-chip microcomputer, and model is PIC16F616.
Above-mentioned wireless signal is an infrared signal.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, this device does not need main frame, saves cost;
2, this device signal is by wireless transmission, and man-machine position need not fixed, and is convenient to the speaker and gives full play to the teaching level, is beneficial to and improves the quality of teaching.
[description of drawings]
Fig. 1 is a structural representation block diagram of the present utility model.
[embodiment]
Below in conjunction with specification drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, the utility model comprises writing pencil, handwriting pad and electronic whiteboard.
Wherein said handwriting pad comprises power supply, pressure inductor, analog-to-digital conversion device, microprocessor, infrared signal emitter, pressure inductor transfers the pressure signal of gathering to electric signal and imports the analog-to-digital conversion device into, digital signal after the analog to digital conversion enters the microprocessor coding, launches in the infrared signal mode by the infrared signal emitter.Microprocessor is a single-chip microcomputer, and model is MK7A11P.
Described electronic whiteboard comprises display screen, center processor, infrared signal receiving apparatus, and the infrared signal that infrared signal receiving apparatus collects enters center processor and decodes, and that continues is presented on the display screen.Center processor is a single-chip microcomputer, and model is PIC16F616.
During use, character and image that the teacher will need to import write on the handwriting pad, the pressure signal that has coordinate record that the contained pressure inductor of handwriting pad will collect transfers electric signal to and imports the analog-to-digital conversion device into, digital signal after the analog to digital conversion enters the microprocessor coding, launches in the infrared signal mode by the infrared signal emitter.The infrared signal that the infrared signal receiving apparatus of corresponding electronic whiteboard collects enters the center processor of electronic whiteboard and decodes, and decoded coordinate information is embodied on the display screen, finishes the output of character and image.
Need to prove; particular of the present utility model is described in detail the utility model; for a person skilled in the art, in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out all within protection domain of the present utility model.
