Specifically, the following steps are included: the bake condition input / the request for the mosquito reel's by the electromagnetic plate controller wire electromagnetic plate of the lateral reel and the longitudinal reel. In this embodiment, the controller is divided into a main controller and a slave controller, and the reel is defined by the following method: _ electromagnetic panel master control defines the sensing area _ a certain horizontal area on the electromagnetic board as a lateral reel, a certain The portrait area is defined as a vertical scroll. In step S102, the scrolling is realized, and the virtual scrolling of the electromagnetic plate reel is realized according to the position change of the electromagnetic pen on the horizontal and vertical reels of the electromagnetic plate. In the conventional electromagnetic plate construction, a plurality of transmitting coils emitting electromagnetic signals are laterally distributed, and a plurality of receiving coils for receiving electromagnetic signals are longitudinally distributed. The electromagnetic pen is designed with a spectral circuit composed of a capacitor and an inductor that receives the electromagnetic signal. The controller controls the lateral transmitting coil to intermittently emit electromagnetic signals by the signal generator. The sensing device on the electromagnetic pen receives the transmitting signal when the lateral transmitting coil transmits the signal. The electromagnetic wave signal that is sensed when the lateral edge ring stops transmitting the signal. Send out, the longitudinal coil receives the electromagnetic pen. 201104551 The electromagnetic signal emitted by the 'longitudinal receiving coil is received by the measuring device and then transmitted back to the main controller'.

The method for determining the movement of the electromagnetic pen on the longitudinal reel is as follows: The lateral line of the electromagnetic plate is controlled by the horizontal line and the sequential transmission signal. The plurality of longitudinal coils in the longitudinal coil group of the electromagnetic plate are sequentially turned on and receive the ring number. The controller determines the longitudinal coordinate of the electromagnetic pen according to the change of the signal received by the longitudinal coil; the plurality of coils in the transverse coil group of the electromagnetic plate sequentially turn on and emit signals, and a longitudinal coil of the longitudinal coil group of the electromagnetic plate is turned on and sequentially receives the signal' The controller determines the abscissa of the electromagnetic pen according to the strength of the longitudinal coil signal; the electromagnetic board controller determines that the electromagnetic pen is swiped on the longitudinal reel according to the abscissa and the ordinate, and realizes the electromagnetic board according to the change of the position of the electromagnetic pen on the longitudinal reel The virtual scroll of the vertical scroll. To achieve a virtual scrolling of the side-scroll, you first need to determine if the stylus is swiping on the side-by-side reel. The controller sequentially controls the plurality of coils in the transverse coil group to conduct and emit electromagnetic signals by the signal generator. When the electromagnetic pen moves in the lateral region defined by the main controller as the lateral reel, the spectroscopic circuit on the electromagnetic pen is in the lateral direction. 201104551 The transmitting coil transmits the signal and reduces the transmitting signal.

The ordinate of the area. 'Main control n to t magnetic money coordinates and ordinate compared to the 胄 magnetic pen in the horizontal reel fan' _ main (four) H to define the position of the electromagnetic pen in the lateral reel as the virtual scroll of the horizontal reel of the electromagnetic plate and output to the computer t ° When implementing a virtual scrolling of a vertical reel, it is also necessary to determine if the electromagnetic pen is swiping within the range of the longitudinal reel. Controlling a coil in the transverse coil group from the controller to conduct and sequentially transmitting the signal 'When the electromagnetic pen moves in the longitudinal region defined by the main control H as the longitudinal reel, the Wei on the electric rotation receives the transmission (four) when transmitting the signal laterally. 'In the horizontal direction _ stop the Wei signal, the detected 201104551 electromagnetic signal is emitted, and the plurality of longitudinal coils in the longitudinal coil group are sequentially turned on and receive the signal emitted by the electromagnetic pen, and the received signal is processed by the measuring device' , phase control, integral, AD digital bit conversion, see the fourth picture, the processed signal is transmitted to the main controller, the main controller determines the ordinate of the electromagnetic pen according to the strength of the signal.

When the electromagnetic pen moves in the longitudinal region defined by the main controller as the longitudinal reel, the resonant circuit on the electromagnetic pen When the lateral transmitting coil emits a signal, the transmitting signal is sensed and received, and the resonant circuit emits the induced electromagnetic signal when the lateral transmitting coil stops transmitting the signal. At this time, a longitudinal coil in the longitudinal coil group is turned on and sequentially receives the electromagnetic pen. The signal, the received signal is processed by the measuring device, and the processed signal is transmitted to the main controller, and the main controller determines the abscissa of the electromagnetic pen according to the change of the strength of the signal. The main controller determines that the electromagnetic pen is swiping in the longitudinal axis range according to the abscissa and the ordinate of the electromagnetic pen, and the main controller defines the position change of the electromagnetic pen on the longitudinal reel as the virtual scrolling of the longitudinal reel of the electromagnetic plate and outputs it to the computer.
