Description of the invention (4) The larger the induced magnetic field near the lead, the larger the Vp value will be. When the operating point is pressed away from the energized lead, the smaller the induced magnetic field, the smaller the Vp value. Due to the A / D conversion value, There is a corresponding relationship with the position, and the device directly represents the pressing position with the A / D conversion value. According to the structure described above, the present invention mainly includes a long straight conductive lead-in device and a microcomputer control device around the input system, a magnetic field induction converter, a signal wired and wireless transmission device. In the present invention, one end of a long straight wire around the coordinate input system is connected to a current and voltage source controlled by a microcomputer, and the other end of the long straight wire is connected to a ground terminal. The conductive grounding device needs to be wrapped with an insulated grounding device outside the current effective end to prevent other unnecessary interference. In summary, the present invention provides a coordinate detection and input system of a new way of thinking, so that the input of coordinates can be used more quickly and stably.
