Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Fig. 1 is a system architecture diagram of the present invention, and as shown in Figure 1, the electronic drawing board system with outdoor scene demonstration and drawing function comprises: electronic brush 10, electronic drawing board body 20, treating apparatus 30 and display screen 40.Wherein, electronic brush 10 can adopt the ultrasound wave pen, and is corresponding, is provided with ultrasonic probe, ultrasonic receiver on the electronic drawing board body.So, electronic brush 10 is launched ultrasound waves, and moves arbitrarily relative to electronic drawing board body 20; Receiver set on the electronic drawing board body 20 is electronic brush 10 ultrasonic waves transmitted message pick-ups, and is sent in the treating apparatus 30, and this treating apparatus can adopt the PC main frame; Afterwards, 30 pairs of ultrasound information that receive for the treatment of apparatus are analyzed, and the current location of localized electron paintbrush 10 demonstrates the picture trace track of electronic brush 10 then by display device 40.
In order to cooperate the signal that receives electronic brush 10, be additional setting the on the electronic drawing board body 20 by ultrasonic receiver that becomes distributed in three dimensions more than four and microprocessor (MCU) the 207 common receiving traps that constitute.Fig. 2 a and 2b are respectively the outward appearance of electronic drawing board body of the present invention and overlook and axle survey synoptic diagram, shown in Fig. 2 a and Fig. 2 b, because electronic drawing board body 20 of the present invention is pressed the 3-D walls and floor design, so three ultrasonic receivers 201,202,203 are separately positioned on x, y, on the z three-dimensional coordinate direction of principal axis, be provided with the 4th ultrasonic receiver 204 simultaneously in the true origin position, the ultrasonic signal time length variation that ultrasonic receiver is sent by receiving transmitter, further judge the variation of distance between emissive source and the reception sources, can measure the three-dimensional coordinate of emissive source, this concrete coordinate location method is open in Chinese patent 98248471.2.In addition, this additional receiving trap that is provided with can be provided with power interface, power switch separately, and the startup that is used for controlling as required the electronic drawing board function whether; Also can increase the function key panel is set, with handled easily; Or increase is provided with video/audio output interface playing back music; Or the adding expansion interface carries out other function expansion.This electronic drawing board body 20 is connected in wired or wireless mode with treating apparatus 30 by signaling interface.
Fig. 3, Fig. 4 are respectively the outward appearance and the structural representation of electronic brush of the present invention, as shown in Figure 3 and Figure 4, electronic brush 10 is that two groups of signal projectors are set in handwriting 102: go up ultrasonic transmitter 101 and following ultrasonic transmitter 103, be provided with the elastic body that can make its generation relative displacement on this between ultrasonic transmitter 101 and the following ultrasonic transmitter 103.This elastic body also can be arranged at down between ultrasonic transmitter 103 and the nib, should go up signal projector this moment and be fixed in handwriting.In the present embodiment, elastic body is a spring.Last ultrasonic transmitter 101 is connected by spring 502 elasticity with following ultrasonic transmitter 103, and therefore, by means of the elasticity of spring 502, the distance between last ultrasonic transmitter 101 and the following ultrasonic transmitter 103 can change.Last ultrasonic transmitter 101 and the different signal of following ultrasonic transmitter 103 emissions as send the ultrasonic signal of different frequency by frequency changer circuit, come from different emissive sources so that ultrasonic receiver is distinguished current demand signal.Whether this electronic brush 10 also can be provided with microswitch, be used to control electronic brush and work.
More particularly, when nib 104 touches the drawing face, promptly during big screen display screen, pressing force changes by the relative position between two transmitters 101,103 and reflects.Be arranged at receiver 201,202,203 on the electronic drawing board body 20 and receive the unlike signal of ultrasonic transmitter 101 and 103 emissions of following ultrasonic transmitter, and be transferred to treating apparatus 30, the unlike signal that treating apparatus 30 is analyzed from last ultrasonic transmitter 101 and following ultrasonic transmitter 103, the relative position of ultrasonic transmitter 101 and following ultrasonic transmitter 103 on the location, calculating pressing force size, at last, the processing by software becomes actual painting effect and reflects on display screen.Electronic brush 10 contacts with electronic drawing board body 20 and when moving, by the design of the pressure sensitivity in electronic brush 10 handwritings perception striking pressure size.3 ultrasonic receivers 201～203 of electronic drawing board body 20 receive the signal of sending, judge the position and the movement locus of pen by the triangle positioning system, after the main control processor of process treating apparatus 30 and the processing of video processor, be converted to vision signal and output on the display device, outdoor scene demonstrates the movement locus of electronic brush 10.
As shown in Figure 5, Fig. 5 is the realization flow figure of the present invention to the electronic brush signal Processing, when electronic brush when electronic drawing board body on the big screen display screen contacts and pushes, at first touch the microswitch of electronic brush, make transmitter group emission ultrasound wave, along with the increase and the minimizing of pressure, the last ultrasonic transmitter of electronic brush is with respect to ultrasonic transmitter generation relative motion down, thereby the position of transmitter group is also changing up and down.When electronic brush moved, the position of transmitter group was also changing up and down simultaneously.Because ultrasonic transmission speed is known, the coordinate P1, the P2 that calculate upper and lower transmitter group to the time value of receiver and mistiming by ultrasonic transmission.Calculate 2 distance P 1P2 of transmitter group up and down, be stored as D1, deduct the decrement that regular length L can obtain spring with D1, this L comprises the former length of the fixed range and the spring of handwriting, thereby calculates force value F=K* (D1-L).Wherein, this regular length L comprises the former length of the fixed range and the spring of handwriting.After electronic brush moves and pushes, calculate the pressure F ' after changing, obtain the changes delta F of pressure according to F, F ', according to the funtcional relationship Δ R=f (Δ F) of pressure and person's handwriting pressure is converted to the changes delta R of person's handwriting radius R again, in like manner can pressure be converted to the depth of color according to function R GB=f ' (Δ F).
As shown in Figure 6, electronic drawing board body 20 is arranged on the big screen display screen 402, in the present embodiment, and electronic drawing board body 20 main finger receiving apparatus, electronic brush 10 contacts with big screen display screen 402, to reach the effect that outdoor scene shows drawn coloured image; Treating apparatus 30 links to each other with big screen display screen 402, the demonstration of control institute drawing picture; The main control processor for the treatment of apparatus 30 also can connect audio process, generates sound signal according to software, and this sound signal is connected to audio output interface by the sound amplifying circuit, and the effect of sound accompaniment is also arranged when realizing drawing thus.
The main control processor for the treatment of apparatus 30 also can external memory circuit and expansion interface circuit, with the image storage of being drawn, and is transferred to large-scale storer by extraneous expansion interface, in hard disk or computing machine; Also can directly output to printing device, as printing on the printer 405; Even can directly be transferred on the network.
