Problems solved by technology
Electromagnetic induction card reading is very important for the application of certain equipment functions, but this invisible thing is easily interfered by various external factors, such as walls, metals, etc., will have a certain impact on it, thus affecting the functional stability of the equipment
like image 3 As shown, the number of traditional coils is one, and there is a through hole in the middle part to place a card reading test device. This detection method has the problem of inconsistent magnetic field strength, and the card reading effect is poor.

The invention discloses a card reading coil winding method, a card reading device and a card reading system, and relates to the technical field of coils. The method comprises a first coil winding step of winding multiple circles according to a preset direction to form a first coil, a second coil winding step of winding multiple circles at a position parallel to the first coil by adopting the same wire to form a second coil, and a coil detection step of detecting whether the first coil and / or the second coil reach the corresponding preset frequency value or not, if yes, stopping winding, if not, adjusting the number of turns, wherein in the second coil winding step, the common edge of the first coil and the common edge of the second coil are wound in an overlapped mode. According to the coil winding method, one center point can be divided into two center point magnetic fields through a two-circle winding method, the card reading capacity of two local areas is enhanced, interference is relieved, and the function stability of equipment is improved.
Description
technical field [0001] The invention relates to the technical field of coils, in particular to a card reading coil winding method, a card reading device and a card reading system. Background technique [0002] Non-contact induction card type, non-contact induction card is an electromagnetic induction card reading method that communicates through electromagnetic waves and magnetic fields, and has no contact points in a remote device. Use this function code to read and obtain relative information status. The lines of force are concentric circles on the same plane and perpendicular to the conductor. Then the generated magnetic field also changes with the distance from the center. This changing magnetic field will induce currents in other loops in its vicinity. That is, the changing current generated by the wire itself produces a changing magnetic field, and this magnetic field further affects the current in the wire; the effect on other wires in the range of this electromagne...
