Description of the Invention: [Technical Field] The present invention relates to a passive interrogator having a charging circuit according to the prior art, and a method according to the prior art for generating a passive inquiry. One of the methods of supplying voltage. [Prior Art] EP 1 871 648 A1 describes an LF interrogator that operates inductively in a frequency range of 125 hemps. The LF interrogator is subdivided into: a battery-backed LF receiver with The three parallel swaying circuit H received in three spatial directions is a passively operated anti-theft locker key circuit that shares the three parallel resonant circuits and in this way returns data by means of a base station. In particular, the fact that the anti-theft lock key circuit has only a small range and has a position-dependent range is flawed. The receiver also requires a large amount of current. In addition, the self-link "http://de _ wiki/RFID" is known as a pure passive interrogator that receives necessary energy from the field of the base station by absorbing modulation without battery support. SUMMARY OF THE INVENTION In view of this background, an object of the present invention is to indicate an apparatus and method for improving the prior art. This object is solved by a passive responder having a technical side circuit and by a method for generating and supplying electric dust with the characteristics of the technical solution. The subject matter of the subsidiary technical solution of the present invention. The first object of the present invention discloses a passive interrogator having a charging circuit for a supply capacitor J60427.doc 201251255, comprising: a first parallel requesting circuit having a 'coil' And a first resonant circuit: a container, wherein the first coil and the first resonant circuit capacitor are coupled with a first section = an interconnect, a first rectifier interconnected with the first node and the supply voltage capacitor a two-parallel resonant circuit having substantially orthogonally aligned to a second coil of the first coil and a second resonant circuit capacitor wherein the first coil and the second coil capacitor and the second a node interconnect' and wherein a second rectifier is provided, the second rectifier being interconnected with: the two nodes and the supply voltage capacitor, and the second rectifier having the same forward direction as the first rectifier In accordance with a second subject matter of the present invention, a method for generating a supply voltage for a passive interrogator is disclosed, wherein two parallel resonant circuit branches are provided in parallel with each other, the two parallel resonances. The circuit branches are respectively connected to the supply voltage capacitor by means of a rectifier, and the supply voltage capacitor is charged by means of one of the induced voltages of the resonant circuit. One of the advantages of the device and the method as taught by the present invention is In the case of a passive interrogator that does not have its own battery-backed voltage supply, sufficient voltage supply for one of the operations of the interrogator can be achieved even in the case of unfavorable alignment of the receiving circuit. By performing absorption preferably by means of a coil, there is essentially an inductive coupling or a transformer coupling in the near field of the base station. These couplings are used in frequency ranges below 5 MHz. Compared to the prior art, By connecting one of the at least two parallel resonant circuits that are mutually orthogonal to each other to charge a supply voltage capacitor, the efficiency is The alignment of the antenna independent of the interrogator relative to the electromagnetic field radiated from the base 160427.doc -6 · 201251255. Applicants' research has shown that the Q factor of the parallel spectroscopic circuits is preferably selected. Above 5 (best, above 1 〇) is advantageous. Under a higher 〇 factor, the resonant circuit voltage increases especially strongly in the case of resonance, and even in the absorption In the case of low field strength of the electromagnetic field, the supply electrical calendar capacitor can also be fully charged to supply energy to the passive interrogator. According to the development scheme, a substantially orthogonal to the second coil is provided and substantially Aligning the second coil of the first coil and the third parallel spectrum circuit of the third spectral circuit capacitor in an orthogonal manner, preferably the third coil and the third resonant circuit f container and the third node And connecting a third rectifier 'connected to the third node and the supply voltage capacitor and wherein the third rectifier has the same positive direction as the first rectifier. By means of an alignment in an orthogonal manner, preferably in an orthogonal manner, the energy supply to the electromagnetic field from any spatial position of the interrogator is = the direction relative to the direction of the emitted electromagnetic field, and the passive supply is supplied It is now omnidirectional. In the mutual transmission scheme, a first modulation signal terminal and the first node second modulation signal terminal and the second node three nodes of the anti-theft lock unit are combined with an alternative embodiment of a third modulation signal. In this manner, the terminals and preferably in the context of amplitude modulation, the base=anti-locking unit reads out the modulated signal received on a carrier from the parallel resonant circuit. Further, the amplitude modulation can be performed by means of the anti-theft lock unit that attenuates the (four) way. Special. In the case where the benefit is combined with the inductance of one of the base stations, it can be read in this way. 160427.doc 201251255 The signal transmitted by the responder should be read and read as the modulation of the carrier. According to a development, preferably, the resonant frequency of the parallel resonant circuits is formed in a range from 20 kHz to 30 MHz kHz [and so on], preferably at 125 kHz, optimally at 13 MHz. It is also preferable to form the resonance frequencies of the three parallel resonance circuits to be almost the same. Preferably, the first rectifier and the second rectifier and the third rectifier are each designed as a separate rectifier diode. The solution between the parallel resonant circuits interconnected into a parallel circuit is achieved by selecting the forward direction of the rectifier diodes such that the capacitors are only charged but not discharged. Thus, the supply voltage capacitor is charged from three parallel resonant circuits (i.e., 'parallel resonant circuits from which the voltage is induced and/or the half voltage is higher than the actual voltage of the charging capacitor). In another development, it is provided to develop a control unit that maintains one of the functional connections to the anti-theft lock. Preferably, the control unit is understood to be an integrated circuit, which is preferably in the form of a parallel resonant circuit and a modulator of the modulator f element & Signal processing. According to an embodiment, a switchable attenuator is connected in parallel to each of the shunt circuit capacitors. The switchable attenuator is connected to the anti-theft lock unit and additionally connected by the anti-theft lock unit to increase the individual The bandwidth of the parallel resonant circuit. In order to improve the detection of modulation and thus the data rate, it is particularly advantageous to increase the bandwidth and the resulting reduced resonant boost during a transmission or reception of a preferably modulated amplitude carrier. In the preferred embodiment, the attenuator is formed as a controllable switch I60427.doc 201251255 (which is preferably designed as a MOS transistor) in series with one of the resistors. In this example, the gate of the MOS transistor is triggered from the anti-theft lock unit. It will be readily understood that in an alternate embodiment, the attenuator is formed from only a single M〇s transistor. In another embodiment, one of the load modulation members in parallel with each of the resonant circuit capacitors is preferably designed to be connected in series from a controllable switch to one of the Zener diodes. One advantage of the Zener diode is that there is almost no current flow below the breakdown voltage, and in fact independently clamps the voltage applied by one of the breakdown voltages to the breakdown voltage independently of the electrical formation. ° In this way 'each parallel attenuation circuit can be attenuated with load to the breakdown voltage of the Zener diode. The respective rectifiers of each of the parallel attenuation circuits are designed as a controllable rectifier unit in accordance with a preferred embodiment. The control input of the controllable rectifier unit is interconnected with the anti-theft lock unit. In this way, the charging of the supply voltage capacitor can be controlled by means of the anti-theft lock unit. It should be noted that the energy supply to the interrogator only occurs by means of absorption modulation and that no supply voltage for the battery is provided to the interrogator. One reason for this situation is the advantageous use of the interrogator as taught by the present invention in the context of the design of a Passive Entry Go System for the failure of a car key. By the fact that there is no need for any battery power >1, even if the battery of the car key is dead, as long as the key is in the vicinity of the car base station and absorbs sufficient energy from the base station, it can be at any time. Turn on the car. [Embodiment] 160427.doc 201251255 The present invention is explained in more detail below with reference to the drawings. Explain similar components with the same symbol.

One of the worm circuit voltages and therefore one of the supply voltages is as high as possible. As the Q factor increases, the bandwidth for data transmission for the burglar locks S to and from the base station decreases. This is due to the difficulty in separating and preparing the modulated signals on the carrier. To increase the bandwidth for data transmission, preferably at least in one of the parallel attenuation circuits (preferably, in all parallels) In the attenuation circuit, it is advantageous to additionally connect the attenuator by means of the anti-theft lock unit. FIG. 3 illustrates a further circuit configuration of the interrogator TR as part of a PES passive keyless entry system. In the following, only the differences in the materials of the embodiment illustrated in Fig. 2 are mentioned. (D), the first-parallel attenuation circuit has a _-switched component that is connected in parallel with the first-vibration circuit capacitor Cx. 160427.doc • 12· 201251255 The first load modulation component Mx is composed of a Zener diode connected in series with one of the controllable switches [not shown]. The control input of the controllable switch and the anti-theft lock unit paper are first adjusted. Change Terminal 臓 interconnection. «Herzine - One advantage of the polar body is that there is almost no current flow below the breakdown voltage, and in fact independent of the current, the voltage applied above one of the breakdown voltages is clamped to The value of the breakdown voltage. In this way, each parallel oscillation circuit can be attenuated to the breakdown voltage of the Zener diode with the load modulation. The second parallel vibration circuit has the second step and the second The vibration circuit capacitor 〇 is connected in parallel to the load modulation component My. Advantageously, the second load modulation component My is composed of a Zener diode and a controllable switch, and the control input of the control switch is The second modulating gate terminal IMY is interconnected by one of the burglar locking units IM. Further, the second parallel resonant circuit has a load modulating element Mz connected in parallel with the third resonant circuit capacitor & Advantageously, the third load modulation element Mz consists of a Zener diode connected in series with one of the controllable switches. The control input of the controllable switch is interconnected with the third modulating gate terminal IMZ of the anti-theft lock unit. The first parallel resonant circuit and the second parallel resonant circuit and the third parallel resonant circuit are each interconnected with an input of one of the LF receiver units LFR. The LF receiver unit L LFR is interconnected with the anti-theft lock unit im by means of a line SA. The LF receiver unit LFR is further interconnected with a microprocessor controlled control unit STM. The control unit STM is interconnected with a single 兀 RFT having one of the HF antennas A and is connected to the anti-theft lock unit by means of a line of eight) and the anti-theft lock unit I60427.doc -13· 201251255. In summary, the control unit STM, the LF receiver unit LFR and the UHF transmitter unit RFT are designed as part of the control unit ST. The control unit STM, the LF receiver unit LFR and the UHF transmitter unit RFT are interconnected with a battery VB as compared to the interrogator TR. Furthermore, the supply voltage capacitor CL is interconnected with the control unit STM. It should be noted that the frequency above 100 MHz is currently designated as UHF. If an adequate supply voltage is generated by means of absorption modulation, the control unit STM can be supplied by means of energy and in this way reduces the energy carried away from the battery VB. . By means of the fact that the individual parallel resonant circuits are both interconnected with the anti-theft lock unit IM and the LF receiver unit LFR, the parallel resonant circuits can be used both for receiving data for the LF receiver unit LFR and for self-theft The locking unit IM receives and transmits data. The control (i.e., a sequential use) of the parallel resonant circuits for the anti-theft lock unit IM or for the LF receiver unit LFR is performed by means of the line SA. When receiving the data for the LF receiver unit LFR, the attenuators DGx, DGy 'DGz are additionally connected by means of the anti-theft lock unit IM to increase the bandwidth. This makes it possible to increase the data rate. With the aid of the attenuators DGx, DGy, DGz, the Q factor, preferably in the range between 10 and 20, is preferably reduced to less than one of ten.
