Embodiment Construction
[0016] The present invention will be further described below in conjunction with Table 1.
[0017] Table 1 is the winding sequence of the electromagnetic whiteboard wire mesh of the present invention.
[0018] In Table 1, the order of winding starts from 21 in the lower right corner, from right to left, from bottom to top, followed by 21, 20, 19...3, 2, 1, then 9, 17, 19... 12, 20, 1, so 21 turns of the wire, until the required wire position, up to 7 cycles, there are 147 wire positions. The line spacing is 1.5cm, and the maximum horizontal or vertical size can be 220cm, which is enough for whiteboards of 100 inches and below.
[0019] In the embodiment shown in the drawings, the horizontal (X) coordinate line numbers are arranged from right to left, and the vertical (Y) coordinate line numbers are arranged from bottom to top. When winding in the forward direction, we call the line with the X coordinate from bottom to top and the line with the Y coordinate from right to left...

The invention discloses a method for winding a wire mesh of an electromagnetic white board. The wire mesh is a plane rectangular coordinate system which is formed by winding electromagnetic wires under a board surface of the electromagnetic white board according to certain rule. The method is characterized in that: a one-wire multi-turn scheme is adopted; both a horizontal coordinate and a longitudinal coordinate only have 21 wires; and the wires are wound in a specified order, so the combination of wire numbers of any adjacent three turns of wires is unique, the minimum interval between the adjacent two turns of wires of the same wire number is nine wire intervals, and a back wire and a forward wire of each turn of wires are spaced by three wire intervals (the back wire and the forward wire of the starting two turns of wires are spaced by one wire interval, and the back wire and the forward wire of the ending two turns of wires are spaced by two wire intervals). By the method, winding and welding processes are greatly simplified, and a control plate is reduced.
Description
technical field [0001] The patent of the present invention relates to a new winding method of electromagnetic whiteboard wire mesh. Background technique [0002] At present, most of the electronic whiteboards on the market are made by using the principle of electromagnetic induction, which are called electromagnetic whiteboards. This kind of electromagnetic whiteboard can detect the coordinate information written or operated by the electromagnetic pen on the board, and transmit this information to the connected computer. The coordinate information is integrated with the computer screen image, and then projected by the projector. to the whiteboard to form a complete interactive presentation system. Here, the electromagnetic pen sends out an electromagnetic signal when writing or operating, and the wire network under the board senses the signal from the electromagnetic pen. The wire net under the board surface is a plane Cartesian coordinate made by winding electromagnetic w...
