At present, the visible patent No. of the relevant document of coiling mode of induction electronic whiteboard inductive layer is 02103069.3 invention, this invention mainly is to form by п shape section to have indented region and to intend antenna loop like the closed region to carry out a multiple antenna loop configuration, it mainly lays particular emphasis on and reduces number of switches and anti-external electromagnetism noise interference, but it has increased the complexity of coil winding, difficulty relatively during production there is no in fact and reduces cost.Simultaneously the patent No. is that 02119706.7 described four or four fraction antenna arrangements of invention are more loaded down with trivial details when it handles port data, and operand is bigger during the coordinate points position, and the usefulness of total system is reduced.
Summary of the invention
The object of the invention is intended to overcome above-mentioned shortcoming, and a kind of quick location, lower-cost direct coding type electromagnetic induction net are provided.
For achieving the above object, the present invention adopts following solution: a kind of direct coding type electromagnetic induction net, comprise several wires, it is characterized in that: the electromagnetic induction net is divided into longitudinal layer and transverse layers, longitudinal layer and transverse layers are to distinguish longitudinally and laterally coiling with several wires, the mutual square crossing of longitudinal layer and transverse layers has constituted equal-sized rectangle induction grid, and the position of each rectangle induction grid all is provided with corresponding coordinate coding.
Above-mentioned direct coding type electromagnetic induction net, it is characterized in that: described several wires indicates not collinear preface code respectively, longitudinal layer and transverse layers by several wires according to many groups of different line preface code combination coilings, its coiling mode is that every lead will be according to a plurality of electromagnetic induction coils of line preface code combination coiling when coiling, article one lead first group of line preface code area after intact, and then jump to second group of line preface code area coiling, the rest may be inferred, and just coiling is intact for article one lead like this; A limit of second lead its coil when first group of line preface code area coiling is passed from the centre of the coil of article one lead coiling; Article three, a limit of lead its coil when first group of line preface code area coiling is near a limit of the coil of article one lead coiling; Remaining lead all gets final product according to this mode coiling.
Above-mentioned direct coding type electromagnetic induction net is characterized in that: every limit of described rectangle induction grid all be by two near different conductor constitute.
Above-mentioned direct coding type electromagnetic induction net is characterized in that: the width that described same lead constitutes several electromagnetic induction coils equates and is 2 times of rectangle induction mesh width.
Above-mentioned direct coding type electromagnetic induction net is characterized in that: an end of the several wires of the described longitudinal layer ground connection that links to each other, and the other end links to each other with multiway analog switch respectively; One end of the several wires of the described transverse layers ground connection that links to each other, the other end links to each other with multiway analog switch respectively.
Above-mentioned direct coding type electromagnetic induction net is characterized in that: the position of described each rectangle induction grid is definite by the horizontal ordinate coding of forceful electric power magnetic induction signal and time forceful electric power magnetic induction signal correspondence in the ordinate coding of forceful electric power magnetic induction signal in the longitudinal layer several wires and time forceful electric power magnetic induction signal correspondence and the transverse layers several wires.
Compared with prior art, the present invention has following advantage:
1, the present invention can adopt direct coding to be provided with corresponding coordinate coding in the position of each rectangle induction grid according to its coiling feature, carry out coordinate setting with this, so it is simple to operate during control, data processing is fast, thereby highly sensitive whole electric whiteboard system is more stable, and it is better to write result of use.
2, electromagnetic induction web frame of the present invention is simple, and coiling is convenient, and is therefore with low cost, is convenient to promote.
