Description
(1) technical field
The invention relates to a kind of antenna loop of EM induction system, particularly relevant for a kind of multiple antenna loop configuration method of EM induction system.
(2) background technology
Because the handwriting recognition circuit arrangement can replace mouse, and more is fit to allow the user carry out the input of literal and pattern in the mode of artificial input than mouse, so the improvement of handwriting recognition circuit arrangement is the field of sharply developing in recent years.Early stage handwriting recognition circuit arrangement is to replace mouse with pen, and in order to promote the user at operational convenience, normally with wireless pen and the two replacement mouse of digiboard (tablet), and the nib of wireless pen usually can be corresponding with the left button of mouse.Year more than though traditional pen type input product has been gone, yet like product all only biases toward in the application of simple functions such as drawing or input in Chinese.
Traditional EM induction system has the transducer/vernier equipment of a digiboard and a mouse or pen type.Generally speaking, on the surface of digiboard, determine the position of a described point that two kinds of operating modes are arranged: one is relative pattern, and another is an absolute mode.General mouse device is with relative mode operating, and when mouse slided on the digiboard surface, computer system can receive the input from mouse, and it only can discern this mouse relatively moving on X and Y direction.Another kind of general technology is to utilize an induction installation forming a pair of mutually perpendicular figure signal in this mouse, and this is vertically corresponding with horizontal mobile phase with this mouse to signal.Relatively, the vernier equipment in the digiboard, for example, wireless pen generally is to operate under absolute mode.If mention this vernier equipment, and move on the another location on its digiboard surface, for this computer system, signal can change to react a new absolute position of this vernier equipment.Now, existing several different methods is with deciding this vernier equipment in the lip-deep position of the digiboard of its support, and wherein, the electromagnetic field inducing technology is a kind of technology that is widely used in absolute mode.Early stage transducer/vernier equipment is to be connected to digiboard by multiconductor cable, and is sent in the computer system through the information of this cable with position and button/pressure.Wireless type transducer/vernier equipment in some conventional art, once transmitted the non-orientation state of transducer/vernier functions of the equipments by the mode of frequency of utilization and/or phase change, these functions have: the pressure of the button of pressing, pen, or similar function etc.Yet if there is not scrupulous processing, the change of frequency and phase place is easily because multiple external factor, as metal, noise, radio magnetic wave or the like, and then causes the error of reading.Particularly in bigger digiboard, these problems become more and more obvious.The improvement technology of traditional digiboard system allows the user to use described point equipment with double mode function mode, therefore can provide to relatively move or the information of absolute position under user's control.
Existing pen type input product normally is a kind of electromagnetic induction circuit arrangement.Electromagnetic induction device generally includes a time writer (electromagnetic pen) and a digiboard (digital tablet).Have a concussion circuit of being formed by inductance capacitance (LC) in the time writer, when touching nib, will produce the variation of inductance value, thereby make the concussion frequency also change thereupon.The variation of the big more then inductance value of pressure of collision nib is big more, thereby the variable quantity of concussion frequency is big more, so imposed on the size of pen point pressure as can be known by the size of frequency variation.Two switch keys are also arranged on the side of wireless pen, leave the tranmitting frequency that produces changes in capacitance in the inductance capacitance oscillator and change pen, change to predict the switch key that the user presses by the difference of frequency by the joint of button.In addition, digiboard (tablet) has also comprised elements such as detector (detector), amplifier (Amplifier), analog-digital converter.The middle section of the handwriting pad of this quasi-tradition is to be loop inductance, has with the equidistant antenna loop of arranging of array way the two-sided of loop inductance.The main application of this antenna loop only is to receive the electromagnetic wave signal that the special electromagnetic pen is launched.When the time writer launching electromagnetic wave, antenna loop will receive this electromagnetic wave, and utilizes the mode of electromagnetic induction to obtain relevant data by digiboard.
Generally speaking, the antenna loop of traditional electromagnetic induction device and layout designs thereof are that antenna loop equidistantly is arranged in grid network with X, Y-axis array, with the induced electricity magnetic pen with calculate its absolute coordinates.Antenna loop configuration with reference to the x axle shown in Figure 1A, every day, the end of line loop A connected a switch (X1 to X25) respectively, and its other end is connected with a ground wire 105A respectively, and whereby, the signal that every day, line loop 110A was responded to can detect by the control to switch X1 to X25.Because magnetic field intensity and square distance are inversely proportional to, the time writer of launching electromagnetic field when far away more, can make that the received signal of antenna loop is faint more apart from antenna; Relatively, the time writer of emission electromagnetic field when near more, can make that the received signal of antenna is strong more apart from antenna.Therefore,, and analyze the received signal power of each antenna loop, be positioned at the scope of that strip antenna just can learn time writer, and then calculate its location coordinate as long as allow the microprocessor all antenna loops of P-SCAN one by one of digiboard.
Yet for large-area digiboard, the antenna loop quantity of its layout also increases thereupon, so need more duplexer.Now, provide a kind of method of utilizing the ㄇ shape district that increases antenna loop can reduce the use amount of duplexer.Shown in Figure 1B, each antenna loop (X1-X9 and XA-XC) is the direction configuration along the X-axis of rectangular coordinates, and it is made up of several ㄇ shape sections 120 respectively.For each antenna loop (X1-X9 and XA-XC) that is arranged in equidirectional, other ㄇ shape section that each ㄇ shape section 120 is adjacent is to adhere to different antenna loops separately, like this, can tell time writer is to be arranged on what person's of antenna loop the ㄇ shape section.For example, the ㄇ shape section 120A of antenna loop X5, the ㄇ shape section antenna 130 and 140 of other antenna loop that it is adjacent is to belong to antenna loop X4 and X6.In addition, another ㄇ shape section 120B of antenna loop X5, the ㄇ shape section 150 and 160 of other antenna loop that it is adjacent is to belong to antenna loop X2 and XC.When the position of time writer is positioned at the ㄇ shape section 120A of antenna loop X5 or 120B, by the signal that is produced with reference to its adjacent antenna loop X4, X6, XC, X2, the position that can tell time writer is to be arranged on the ㄇ shape section 120A or 120B of antenna loop X5.As mentioned above, the number of switches among Figure 1A (25 switches) is greater than the number of switches among Figure 1B (12 switches).
In traditional method, must be noted that the distance between the two adjacent ㄇ shape sections in the same antenna loop (for example: the distance L between two adjacent ㄇ shape section 120A, the 120B among the antenna loop X5).If spacing L is too little, then when the position of decision time writer, easily cause the result of erroneous judgement.On the other hand, information products develop the fast more easy more phenomenon of supervening electromagnetic interference of processing speed towards two-forty processing, H.D direction now.Usually in the specific occasion of using digiboard, often be accompanied by the existence of other message digit products around it.Required have for the large-area digiboard for commercial, the quantity of its antenna arrangement increases thereupon, and this certainly will increase a large amount of duplexers; Therefore, in order to reduce the use amount of duplexer, and propose to increase the method for the ㄇ shape section quantity of antenna loop, this causes the increase of antenna length; Because the increase of antenna length more is subject to the interference of electromagnetism noise, and then influences the correct calculation of time writer position.In addition, be to be traditional antenna arrangement shown in Fig. 1 C, in traditional antenna arrangement, X-axis is connected ground wire 105A and 105B respectively with the antenna arrangement of Y-axis, and the configuration of antenna loop 110A and 110B can exceed the scope of ground wire 105A and 105B.Therefore, traditional digiboard must be reserved borderline region 170 and exceed part antenna loop 110A and the 110B of ground wire 105A and 105B with storing, and the restriction that this causes the downsizing of handwriting pad area causes being difficult to make the panel with undersized borderline region.In view of this, the invention provides a kind of multiple antenna loop configuration of EM induction system, to solve above-mentioned defective.
