Description
Technical field
The utility model relates to a kind of electric whiteboard system, especially a kind of interactive electric whiteboard system.
Background technology
Dustless teaching aid develops into the electric whiteboard system stage, mainly contains two kinds of implementations:
1, referring to Chinese patent: " a kind of shatter-resistant fine motion photoelectric pen "; The patent No.: 201020694292.0, comprise the shaft of a writing brush and the illuminating circuit that is arranged in the shaft of a writing brush in its structure, shaft of a writing brush front end set inside nib interlock pipe; In this nib interlock pipe the luminous signal lamp is set; Nib interlock pipe rear end contacts with microswitch on being arranged on luminous circuit board through the bounce-back power cutoff mechanism, and the luminous circuit board rear end is provided with battery tray, and the battery tray rear end is the terminal cap for brush; Luminous signal lamp, microswitch, luminous circuit board and power supply compose in series illuminating circuit through lead.During work, utilize this lettering pen that can initiatively launch light signal to carry out electronic writing, write signal and be presented on the screen realization electronic reciprocal through handling to form behind the signal receiving device receiving optical signals.
2, referring to Chinese patent: " a kind of interactive photoelectricity display screen "; The patent No.: 201020109926.1; The infrared transmitting tube that comprises display screen in its structure, is positioned at the imageing sensor on the display screen and is provided with near imageing sensor, the frame of display screen is provided with reflective membrane; During work, infrared transmitting tube is to the infrared light of reflective membrane emission specific wavelength, the infrared light that the imageing sensor collection is reflected by reflective membrane; When pointing, when any light tight material such as teacher's pointer is placed on the display screen,,, can on display screen, demonstrating handwriting trace through processing of circuit because of its blocking-up is the imageing sensor perception by light path of reflective membrane to imageing sensor.
