2Value be read out device 20 and read, then be arranged on first and second line defcts 71 between the transceiver device 10 and be arranged in the response range of reader 20, thereby and be positioned.The accuracy of described position fixing process can reduce delivering power by radius and/or the solid angle that reduces response range 2011, and/or use directional antenna to improve.
Fig. 6 represents to be used for the circuit of the transceiver device 10 of cable 40 of the present invention.This circuit has the memory 123 that 122, one of processors that transmitter 124 being connected to antenna 11 separately and 125, one of receiver be connected to transmitter 124 and receiver 125 are connected to processor 122.This circuit also has a rectifier 120 that is connected to antenna 11, so that to processor 122, transmitter 124 and receiver 125 supply dc voltages; Also have a clock controller 121 that is connected to antenna 11, be used for providing system clock C to processor 122.Also provide a rechargeable battery, so that to rectifier 120 supply voltage V.In this case, rechargeable battery recharges preferably and can not use electric wire.This shows that transceiver device all is utilizable at any time after the of short duration charging stage of process.Adopt radio link that rechargeable battery is charged, and needn't excavate and expose cable and transceiver device.Rechargeable battery can not done so yet, but is charged by ground by the user.
Certainly, also can adopt pure passive system.In this case, need not provide the rechargeable battery 126 shown in Fig. 6.Do not power to transceiver device in order there to be the seedbed, power supply is taken from by reader to the electric field that antenna 11 sends, and is used for moving transceiver device.
Fig. 7 represents reader 20 and according to the electromagnetic coupled between the typical embodiments of the circuit of transceiver device 10 of the present invention.Another antenna 21 of the antenna 11 of transceiver device 10 and reader 20 is all taked the form of coil, induction coupling between the coil.The inductance of antenna 11 and input capacitance 1251 forms antiresonant circuits, and resonant circuit is by the winding resistance 111 and load resistance 1252 decay of antenna 11, its resonance frequency be tuned to the transmission frequency of reader 20.
In another antenna 21 of reader 20, produce a radio frequency alternating magnetic field, so that read the numerical data 1231 that is stored in the transceiver device 10.This just causes inducing radio frequency AC voltage in the antenna 11 of transceiver device 10.Be used for the dc voltage and the clock frequency of the timely clock system of power supply of processor 122, derive from radio frequency AC voltage.
Switch S is controlled by the dateout O that the processor 122 from transceiver device 10 sends transmitter 124 to.For example, high level is corresponding to the closure state of switch S, and low level is corresponding to the off-state of switch S.When switch S was closed, other load resistance 1253 was connected in parallel with load resistance 1252.Therefore the total load resistance of antiresonant circuit changes according to the state of switch S.If load resistance is lower,, a bigger electric current flows through antenna 11 with regard to being arranged.The variation of total load resistance causes the electric current in the antenna 11 to change, and as the result of induction coupling, also produces an auxiliary voltage in another antenna 21 of reader 20.Thereby make dateout O be sent to reader 20 from transceiver device 10 by means of this so-called transformer coupled.
