Accompanying drawing of the present invention is only for illustrating relative position relation, and the size at some position have employed the plotting mode of lavishing praise on oneself so that understand, and the size in accompanying drawing does not represent the proportionate relationship of physical size.
Composition graphs 1 to Fig. 5 describes structure and the recognition methods of the input object recognition device of the embodiment of the present invention.Input object 200 can be the entity being configured with RFID label tag.RFID label tag has global unique ID code, and has information storage and information editing's characteristic.RFID label tag can be taked to paste or slip into actual object surface or it is inner, makes actual object have ID coding.Input object recognition device 100 comprises touch screen 110, RFID card reader matrix 120 and control module 130.
Touch screen 110 is configured to sense input object 200 in sensing area 140 to obtain the first signal.First signal comprises the electric signal representing the position of input object in sensing area 140.Such as, the coordinate of the XY in the coordinate axis that input object 200 formed at sensing area 140 can be obtained according to the first signal.Touch screen 110 can be the one in resistance type touch control screen, capacitance type touch control screen, infrared-type touch screen or surface acoustic wave type touch screen.Below in conjunction with Fig. 3 and Fig. 4, illustrate that touch screen 110 senses the mode of input object for capacitance type touch control screen.
Touch screen 110 can be utilize electric current to respond to the capacitance technology touch-screen CTP (CapacityTouchPanel) realized.In one embodiment, touch screen 110 can be compound glass screen.Such as, touch-screen 110 comprises upper strata glass 111, upper strata transparent conductive film 112, transparent viscose 113, lower floor's glass 114 and lower floor's transparent conductive film 115 (see Fig. 2) successively under upper.Transparent conductive film can be ITO conductive film.Upper strata transparent conductive film 112 is provided with multiple electrode 116.Multiple electrode 116 can be arranged on four angles of upper strata transparent conductive film 112, when input object touches touch screen 110, input object and upper strata transparent conductive film 112 form a coupling capacitance, due to upper strata transparent conductive film 112 being connected to high-frequency signal, so input object absorbs a very little electric current, this electric current flows out respectively from the electrode 116 four angles of upper strata transparent conductive film 112.The electric current and the input object that flow through four electrodes 116 are proportional to the distance of corner, can calculate the position of input object thus.
In another embodiment, touch screen 110 can also utilize the touch technology of projection-type.Such as, upper strata transparent conductive film 112 and lower floor's transparent conductive film 115 etch respectively the line pattern along X-direction and Y-direction.Because two line patterns are positioned at different surfaces, its intersection forms a capacitive node.A line pattern can as drive wire, and another one line pattern can as detection lines.When the wire of electric current in drive wire, if there is the signal of capacitance variations in the external world, the change of capacitive node on another sandwich circuit figure so will be caused.The change of detecting capacitance can be obtained by the loop measurement be attached thereto, then draws the position of input object as calculated.
In yet another embodiment, touch screen 110 realizes multi-point touch by the electrode increasing mutual capacitance.Such as, touch screen 110 is divided into multiple region, one group of mutual capacitance module is set in each region.Each mutual capacitance module works alone, and makes touch screen 110 independent detection to the touch-control situation in each region, after processing, realizes multi-point touch simply.
Those skilled in the art can also realize more how different touch screens 110, do not repeat them here.
RFID card reader matrix 120 is positioned under touch screen 110, comprises multiple RFID card reader module 121.Preferably, multiple RFID card reader module 121 arranges along the direction of row and column.RFID card reader matrix 120 is configured to sense input object 200 in sensing area 140 to obtain secondary signal.Particularly, each RFID card reader module 121 reads encodes with the ID of the RFID label tag of the input object 200 of RFID card reader matrix mutual 120, this ID coding uniquely tagged input object 200.Each RFID card reader module 121 has address code.Secondary signal comprises the ID coding of the address code of at least one the RFID card reader module 121 sensing input object 200 and the RFID label tag of input object 200, and this address code is corresponding with the coordinate in induction zone 140.Preferably, the corresponding relation of the coordinate in address code and induction zone 140 is stored in control module 130.Like this, the coordinate of the XY in the coordinate axis that input object 200 formed at sensing area 140 can be obtained according to secondary signal.Below with reference to Fig. 2 and 5, the embodiment that RFID card reader matrix 120 provided by the invention senses input object is described.
Each RFID card reader module 121 has address code, such as, and B0, A1, the B2 etc. shown in Fig. 5.Address code is corresponding with the coordinate of the coordinate axis of induction zone 140.When input object 200 is when address code is between four RFID card reader modules 121 of A29, B30, B38, A39, address code is the ID coding that the RFID card reader module 121 of A29, A39, B30, B38 reads the RFID label tag of input object 200.Secondary signal at least comprises address code A29, B30, B38, A39, can calculate the position 140 of input object 200 in induction zone by the coordinate corresponding in induction zone 140 according to address code A29, B30, B38, A39.
Further, mutually interference and the recognition effect of impact to RFID label tag between adjacent block in RFID card reader matrix 120, RFID card reader matrix 120 provided by the invention comprises the spaced multiple first RFID card reader modules A in direction along row and column and multiple second RFID card reader module B.When multiple first RFID card reader modules A work, multiple second RFID card reader module B quits work; Otherwise when multiple second RFID card reader module B works, multiple first RFID card reader modules A quits work.The job control of the first RFID card reader modules A and the second RFID card reader module B can carry out multidimensional by control module 130 and control.Preferably, duty switching time between RFID card reader module is Millisecond, switched by working time difference and avoid, due to the distance too closely interference produced, solving interference problem further with this, also can not affecting the recognition speed of RFID card reader matrix 120 pairs of RFID label tag simultaneously.Such as, when input object 200 is when address code is between four RFID card reader modules 121 of A29, B30, B38, A39, the ID that two RFID card reader modules 121 of address code to be two RFID card reader modules of A29, A39 and address code be B30, B38 read the RFID label tag of input object 200 respectively within the very little time interval encodes, and then can judge that input object 200 is positioned at four RFID card reader modules 121 that address code is A29, B30, B38, A39.
In certain embodiments, RFID card reader module can be the RFID card reader integrated circuit communicated with RFID label tag with 13.56MHz frequency.The Card Reader chip of RFID card reader integrated circuit, by complete the integrating of modulation and demodulation circuit of standard, support all with the RFID label tag communications protocol of 13.56Mhz frequency for communication, and pin mates mutually.Preferably, RFID card reader supports all underlying protocols of ISO14443A standard.The technology ultimate principle of RFID card reader is the transport property utilizing radiofrequency signal or Space Coupling (inductance or electromagnetic coupled), realizes the automatic identification to object.Data are stored among electric data carrier (claiming electronic tag or label), the energy supply of electronic tag and the exchanges data between electronic tag and card reader are not contacting by electric current but by radio electromagnetsm field, radio-frequency (RF) identification is the abbreviation of radio frequency identification, is namely carried out the identification of RFID label tag by radiowave.
