Specific embodiment
The embodiment of the present invention is further described below in conjunction with accompanying drawing：
A kind of paper chart drawing method based on active electromagnetic pen, is based on active electromagnetic pen, numeral
Change what plate was realized.
As shown in figure 1, the two of active electromagnetic pen (Active Electromagnetic-induction Pen)
End is respectively equipped with emitting head and battery compartment, and galvanomagnetic signal transmitter is provided with inside induction pen, and battery is provided with battery compartment,
Emitting head, galvanomagnetic signal transmitter and battery are linked together, and operation button is provided with induction pen, and operation button includes " rising
Initial point ", " impact point ", " amount is calculated " and " course line drafting " button, when each operation button is operated, time writer launches various differences
The signal of frequency, realizes the simple input for marking and drawing operational order.
As shown in Figure 2 and Figure 3, X-axis aerial array, Y-axis aerial array are connected with digitizing tablet, inside digitizing tablet
Circuit is provided with processing module and display control control module, and processing module is connected with display control module, display control module
Output end connects display screen and laser galvanometer.The processing module includes the wave filter, signal processing circuit, the X/Y that are sequentially connected
Termination power and frequency determining circuit, the wave filter are connected with X-axis aerial array, Y-axis aerial array, the X/Y couplings
To display control module, the frequency determination module exports operational order to display control module to circuit output coordinate.Work as numeral
After changing the electromagnetic signal that plate receives electromagnetic pen transmitting, internal circuit one is to all X/Y axle antennas for sensing signal
Array is scanned, it is determined that sensing central point, completes being accurately positioned for coordinate；Two is that signal frequency is analyzed, according to this
Pattern set by frequency carries out computing and treatment.
The processing procedure of digitizing tablet internal circuit is：Processing module is sent to after electromagnetic signal is received when antenna to enter
Row filtering process, according to antenna receiving sensitivity setting signal intensity threshold, is considered useful signal, i.e., higher than the signal of threshold value
The electromagnetic signal that induction region internal antenna is sensed in Fig. 2.Fusion treatment is weighted to every road antenna valid signal strengths, is melted
Close processing example as follows：Assuming that X-axis antenna X1, X2, X3, X4, X5 output useful signal, antenna pair answer X-coordinate respectively P1,
P2, P3, P4, P5, according to sensing that signal intensity determines blending weight respectively D1, D2, D3, D4, D5, then merge output coordinate
PX=P1*D1/D+P2*D2/D+P3*D3/D+P4*D4/D+P5*D5/D, D=D1+D2+D3+D4+D5 in formula.At Y-coordinate fusion
Reason is similar with X-coordinate processing method.The frequency determination module of processing module is synchronously analyzed to electromagnetic signal frequency, according to pre-
The frequency for first setting and operational order corresponding relation, carry out respective operations.
The electromagnetic induction sensitivity of X/Y axles aerial array is higher on digitizing tablet, arrange tightr, can sense electromagnetism
The region of signal is bigger, output signal loop is more, is got over by coordinate pickup resolution ratio and precision after signal transacting
It is high.Required precision is picked up according to the coordinate that sea chart marks and draws platform, the scope in electromagnetic induction region is set, design based on digital plate is apart from glass
Glass upper surface is 12mm, X/Y axles aerial array interval 5mm, is evenly arranged in plotting region (700mm × 1000mm), to protect
Card effectively pickup scope, antenna is also disposed with ± 5mm, ± 10mm positions, and X-axis antenna adds up to 205 beams, and Y-axis amounts to antenna
There are 145 beams.
Active electromagnetic pen can realize the pickup of point contact type coordinate and signal control function.Due to electromagnetic pen pen
Point is relatively thin, and the electromagnetic signal of transmitting is more concentrated, and array output of the signal processing module to electromagnetic induction region is carried out at signal
Reason, it is accurate to calculate sensing center point coordinate, realize that point contact type coordinate is picked up.When not operated, electromagnetic pen transmitting electricity
Magnetic signal frequency is F0, after digitizing tablet detects the frequency signal, reads changing coordinates and is shown on a display screen.
" starting point " is pressed on electromagnetic pen, and the secondary frequencies of rapid fire three are the electromagnetic signal of F1 afterwards, and digitizing tablet is consecutively detected three
It is judged to effective control signal after secondary same frequency signal；" impact point ", " amount is calculated ", " course line drafting ", respective frequencies similar with its
Respectively F2, F3, F4.Digitizing tablet detects the signal of different frequency, carries out various operations and completes plotting.

Step 1：Electromagnetic pen nib point is touched into starting point on paper chart, operation electromagnetic pen " starting point " is pressed
Button, it is F1 to send electromagnetic signal frequency, after digitizing tablet detects signal, reads current time coordinate, is completed to starting point
Coordinate is picked up.
Step 2：By the striking punctuate 1 of electromagnetic pen nib point on paper chart, operation electromagnetic pen " impact point " is pressed
Button, it is F2 to send electromagnetic signal frequency, after digitizing tablet detects signal, reads current time coordinate, is completed to impact point 1
Coordinate is picked up.
Step 3：By the striking punctuate 2 of electromagnetic pen nib point on paper chart, operation electromagnetic pen " impact point " is pressed
Button, it is F2 to send electromagnetic signal frequency, after digitizing tablet detects signal, reads current time coordinate, and it is right that digitizing tablet is completed
The coordinate pickup of impact point 2.Operate successively, the coordinate pickup to impact point N can be completed.
Step 4：Operation electromagnetic pen " course line drafting " button, it is F4, digitizing tablet detection to send electromagnetic signal frequency
To after signal, sea chart marks and draws platform and carries out course line drafting according to the starting point of record, the coordinate of impact point 1,2...N, while aobvious
Display screen display drawing result (1 i.e. from starting point to impact point, from impact point 1 to impact point 2 ... impact point N-1 to impact point N
Course line path).
The present invention can also operate electromagnetic pen " amount is calculated " button after step 3, and it is F3 to send electromagnetic signal frequency,
After digitizing tablet detects signal, sea chart marks and draws coordinate carry out amount calculation of the platform according to the starting point, impact point 1,2...N of record,
Result (from starting point respectively to the azimuth-range of impact point 1,2...N) is calculated in display screen displayed quantity simultaneously, so that realization amount
Calculate function.
During actual verification, building Proof-Of Principle platform according to above-mentioned principle scheme carries out checking test, experiment knot
By show coordinate pickup resolution ratio can reach 0.5mm, by operating button on active electromagnetic pen, by multiple targets
