In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
The structure shown according to these attached drawings obtains other attached drawings.
Fig. 1 is the structural schematic diagram of the intelligent drawing board preferred embodiment of the present invention；
Fig. 2 is the intelligent drawing board circuit module figure of the present invention.
Drawing reference numeral explanation：
The embodiments will be further described with reference to the accompanying drawings for the realization, the function and the advantages of the object of the present invention.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art obtained without creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute is only used in the embodiment of the present invention
In explaining relative position relation, motion conditions etc. under a certain particular pose (as shown in the picture) between each component, if should
When particular pose changes, then directionality instruction also correspondingly changes correspondingly.
In addition, the description for being related to " first ", " second " etc. in the present invention is used for description purposes only, and should not be understood as referring to
Show or imply its relative importance or implicitly indicates the quantity of indicated technical characteristic." first ", " are defined as a result,
Two " feature can explicitly or implicitly include at least one of the features.In addition, the technical solution between each embodiment can
To be combined with each other, but must can be implemented as basis with those of ordinary skill in the art, when the combination of technical solution occurs
Conflicting or cannot achieve when, will be understood that the combination of this technical solution is not present, also not the present invention claims protection model
Within enclosing.
Referring to figs. 1 to 2, technical solution of the present invention proposes a kind of intelligent drawing board 100, including drawing board host 10, drawing board host
10 include central processing unit 11 and the display screen 13 being connect with central processing unit 11, and resistive touch is also installed on display screen 13
Screen 30；Infrared touch frame 50, resistive touch screen 30 and infrared touch frame 50 are provided on 30 edge of resistive touch screen in
Central processor 11 connects.
Technical solution of the present invention is infrared by using being equipped with infrared touch frame 50 on the edge of resistive touch screen 30
Touching box 50 is launched be close to screen before gather X, the infrared ray matrix in Y-direction, when there is touch, object will block by
The vertical and horizontal infrared ray of the position, after touch screen finds when scanning and firmly believed that an infrared ray is obstructed, expression may have touch, together
When change to another coordinate at once and scan again, if finding that an other axis also has an infrared ray to be obstructed again, indicate to find to touch, and
The object space for obstructing infrared ray is reported to central processing unit 11, judges touch point in the position of display screen 13 by calculating
It sets.When user's writing brush, when brush carries out calligraphy or painting creation, writing brush, brush can block the infrared ray by the position,
Contact coordinate information of the meeting of infrared touch frame 50 by writing brush with brush is reported to central processing unit 11, judges to touch by calculating
Point is in the position of display screen 13.By analysis, it calculates, so that it may really to restore the writing of user or track of drawing a picture
Coming, still further aspect, central processing unit 11 can also show the writing of reduction or track of drawing a picture on display screen 13,
User can see the calligraphy work or paint that oneself is drawn on display screen 13 immediately, and it is convenient to draw, and has
The function of dynamic creation displaying.
It should be noted that those skilled in the art can be as needed, infrared touch frame 50 is changed into optical touch screen,
The LED light in the top upper left corner of optical touch screen launches light, is reflected by surrounding reflection bar, and the CCD into the upper right corner takes the photograph
As in head.Similarly, the light to gather in the CCD camera in the incoming left side of light of the LED light transmitting in the upper right corner is in touch area
One reticule of interior formation.When touch point enters the reticule, the injection light of the point and light shape is received in an angle,
The straight line constituted between the CCD camera and this two light and two cameras at both ends simultaneously can form two angles again,
The coordinate of the point can select other touches according to actual needs by 11 accurate typing of central processing unit, technical staff in this way
Screen, details are not described herein.
Specifically, in specific assembling process, display screen 13 is matched with the lower surface of resistive touch screen 30
Setting.So set, display screen 13 is located at the downside of resistive touch screen 30 and overlaps, then from the user's point of view, picture

The usage experience at family.
Still further aspect, as shown in Figure 1, resistive touch screen 30 also includes opposite first edge 31 and second edge
33, and connection first edge 31 and second edge 33 and third edge 35 and the 4th edge 37 relative to each other；On the first side
Edge 31 is equipped with infrared transmitting tube in the one edge in second edge 33, and infrared receiver is equipped in another one edge
It manages, infrared transmitting tube is installed in the one edge in third edge 35 and the 4th edge 37, is installed in another one edge
There is infrared receiving tube.This makes the infrared light path between first edge 31 and second edge 33 and third edge 35 and the 4th side
Infrared pipeline between edge 37 in touch detection region (13 region of display screen) forms the infrared light grid of intersection.Work as touch
In touch detection region striking occurs for object (finger, writing pencil, writing brush, the brush of such as user), will block at least two
Infrared light path, and the position of the infrared receiver and infrared transmitting tube corresponding to every infrared light path is fixed, centre
Reason device 11 judges the position of the intersection point for the infrared light path being blocked, and the position of the intersection point is the position of touch objects, to realize
Positioning to touch objects.
In addition, in order to realize the good connection of infrared touch frame 50 and central processing unit 11, also set up on drawing board host 10
There are USB interface, USB interface one end to be electrically connected with infrared touch frame 50, the other end and central processing unit 11 of USB interface are electrical
Connection.During specific use, a data line being attached thereto, data line other one are set on infrared touch frame 50
