Abstract
The utility model discloses a non-projection electronic whiteboard, which belongs to the field of multimedia teaching, and comprises a rear panel, a panel body, a surface screen and an information output interface, and is characterized in that the panel comprises an information input interface 1, a display control module, a display screen, a surface screen, a stroke sensor 2 and a stroke processing module. The stroke sensor 2 is of a scanning grid which is formed by infrared ray receiving and transmitting tubes which are densely distributed on the periphery of the display area on the horizontal and vertical directions, so a scanning plane net is formed, through the blocked infrared rays on the horizontal and vertical directions, the X and Y coordinates are confirmed. Compared with the prior art, the utility model has the characteristics of good multimedia teaching display effect, greater teaching flexibility for teachers, lower cost and durability.
Description
[technical field]
The utility model relates to a kind of electronic whiteboard, particularly a kind of non-projection electronic whiteboard.
[background technology]
Electronic whiteboard is the very suitable a kind of instrument of present multimedia teaching, meeting or the like occasion, and it can carry out information communication with computer.How electronic whiteboard is connected to PC in actual the use, utilizes projector that the content on the PC is projected on the electronic whiteboard screen, under the support of special application program, can construct a giant-screen, interactively cooperation meeting or teaching environment.Utilize specific pen with means for holding it in right position to replace mouse, can move Any Application, any operation that can edit file, note, preservation etc. utilizes keyboard and mouse to realize on computers at the enterprising line operate of blank." blank teaching " do not compared with " one wipe promptly have " of traditional blackboard, and electronic whiteboard can real time record, preserve the overall process of learning aid, and the teacher calls the classroom instruction data of storing in the computer at any time, needn't worry that the content of writing on the blackboard can't be reappeared again.Simultaneously, electronic whiteboard is realized positive interaction by teacher and student in classroom instruction, help to improve students'interest in learning, is the good utility appliance of variation teaching at present and creative teaching.But present electronic whiteboard is realized by projector because signal transmits, and projector generally is installed in the ceiling central authorities in classroom, can stand on projection ray's projected path unavoidably during teachers ' teaching, cause the teacher to receive that light stimulus interrupts teaching process on the one hand, another convenient meeting cast shadow on blank, having influenced teaching efficiency, is exactly to be projected in the angle that has on the blank to watch and have reflectively in addition, influences display effect.
The touch-screen that also has a kind of automated instruction to use on the market is in order to conduct to processor with the pressure information on the screen, to excite the action that opens or closes a certain page.Its structure is two-layer pressure sensitivity film for touch-screen inside has, when touch screen surface a bit was under pressure, two membranes formed short circuit in this, and touch screen controller detects the coordinate figure of pressure spot rapidly, carry out fast processing simultaneously, signal is passed to processor carry out information processing.But this equipment is the pressure sensitivity technology because of what adopt, and the physics of screen is had relatively high expectations, and is simultaneously also very strong for the size requirements of pressure, in use easily causes the screen wearing and tearing, and the life-span is limited.
[summary of the invention]
Technical assignment of the present utility model is at above the deficiencies in the prior art, and a kind of non-projection electronic whiteboard is provided.
The technical scheme in the invention for solving the technical problem is: a kind of non-projection electronic whiteboard, comprise backboard, plate body, table screen, information output interface, it is characterized in that: comprise information input interface 1, display control module, display screen, stroke inductor 2, stroke processing module in the plate body.
Above-mentioned information input interface 1 is a high-definition multimedia HDMI interface.
Infrared ray around above-mentioned stroke inductor 2 is served as reasons and gathered in the viewing area receives and the scanning grid of power valve formation level and vertical direction, forms a plane of scanning motion net, determines X, Y coordinate by the level that is blocked and the infrared ray position of vertical direction.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, non-projection display mode has avoided teacher's shade to stop, the teacher has bigger teaching dirigibility;
2, the reflective and shade of having avoided projection to cause has guaranteed the display effect of multimedia teaching;
3, the stroke inductor utilizes infrared technology, and is more lasting than pressure inductive, induction life-span;
4, very fast because of the aerial velocity of propagation of infrared ray, more ultrasonic induction type, stroke induction more in real time, responsive more.
[description of drawings]
Fig. 1 is a structural representation 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 backboard, plate body, table screen, information output interface, also comprise information input interface 1, display control module, display screen, table screen, stroke inductor 2, stroke processing module.Described information input interface 1 is a high-definition multimedia HDMI interface, and the information output interface is a USB interface.
Infrared ray around described stroke inductor 2 is served as reasons and gathered in the viewing area receives and the scanning grid of power valve formation level and vertical direction, form a plane of scanning motion net, determine X, Y coordinate by the level that is blocked and the infrared ray position of vertical direction, come the position of positioning signal pen.Because the aerial velocity of propagation of infrared signal is higher than hyperacoustic velocity of propagation far away, therefore in the blank zone, the travel-time that can ignore infrared signal, with infrared signal as system time reference, determine travel-time, the time delay of ultrasound wave in the blank zone, and then the distance of definite sign pen or blackboard eraser and stroke inductor 2, finally obtain sign pen or the blackboard eraser coordinate on blank.Rely on this technology, mouse and keyboard without computing machine, just can carry out the operation of all computing machines by available onboard lettering pen, classroom explanation process can be punctuated arbitrarily, note, synchronous recording is exported at random, save the time that the student takes notes, the notes under the class can be convenient, quick when arrangement.
The utility model has been broken away from projector, so when selecting electronic whiteboard surface, can select common panel, this kind panel price is cheap, can write with straight the connecing of conventional oil, does not stay any vestige after wiping.Because the projection electronic whiteboard need be selected the Opti-pro panel for use for preventing solar effect (being that dazzling hot spot is arranged on the plate face), this kind panel price is higher, and can not directly write with oil pike.So production cost of the present utility model is lower, has the stronger market competitiveness.
The utility model can be installed with wall-hanging, chute type, movable type, closet formula.
Except that the multimedia classroom instruction, the utility model can also be used for fields such as teleconference, commercial exhibition, knowledge training, fire bill, military commanding, traffic pool.
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.
