If the position determination system POS is the GPS system, the PO signal can also be transmitted in the L-band of the GPS signal.
  • An interruption of the signal transmission connection VER between the antenna unit ANE and the receiver EMP of the toll collection unit EIN can easily be detected by detecting the presence or absence of this pool signal at the receiver EMP or the antenna unit ANE by a forcing control unit FKE, for example a correspondingly programmed signal processor the control signal SIG can be generated in predefinable time intervals.

Electrical properties are understood to mean quantities such as impedance, etc.
  • the function control unit FKE can have its own signal generator. Of course, it is also possible that the signal generator is spatially separated from the Fur_tionskontroUaji FKE.
  • the term function control unit FKE means a unit consisting of a process control for carrying out the method according to the invention and a signal generator.
  • the function control unit FKE can also be implemented in an integrated form as a chip.
  • control signal SIG is generated, for example, in the form of a continuous wave sinusoidal voltage and if the impedance Zt, the antenna unit ANE deviates from the impedance Zo of the signal transmission connection VER, then the amount of the control signal SIG fluctuates periodically between a maximum and a minimum value. This fluctuation, the standing white, is caused by the phase connection between the injected and reflected white.
  • the ratio between the maximum and minimum values of this voltage is the voltage-standing ratio ⁇ and is related to the reflection coefficient r using the following equation:
  • the return loss ⁇ which is the logarithmic measure of the reflection coefficient r, can be determined using the following formula:
  • the signal transmission connection VER between the antenna unit ANE and the receiver unit EMP can be classified as faulty and a field function of the antenna unit ANE can be diagnosed become.
  • Time domain reflectometry has proven to be particularly suitable for the function control of the antenna unit ANE.
  • the function account unit FKE can feed the control signal SIG into the signal transmission connection VER to be checked, for example in the form of a positive voltage rise.
  • the control signal SIG travels along the transmission line.
  • the impedance of the antenna unit ANE corresponds to the characteristic impedance of the transmission line, no signal is reflected at the transition between the signal transmission connection VER and the antenna unit ANE. However, if there is a mismatch on the antenna unit, part of the input voltage is reflected.
  • the reflected control REF of the control signal SIG can be easily identified by the function control unit FKE, since it is separated in time from the control signal SIG. This time difference can be used to determine the length D of the transmission link between the functional account unit FKE and the discontinuity. This length D is calculated as:
  • v p is the speed of propagation of the control signal SIG and T is the transit time from the functional account unit FKE to the fault control and back.
  • the speed of propagation v p can be determined experimentally with a cable of known length of the same type. Knowing the propagation velocity v p as well as the measured time difference between feeding the control signal SIG and detection of the reflected REF signal, the disturbance control can be clearly localized.
  • the nature and the size of the mismatch can be determined based on the shape of the reflected part REF - the reflected WeUe. Knowing the control signal SIG and the reflected signal REF, as measured with the functional account unit FKE, allows, as is known, the determination of the load impedance ZL as a function of the impedance Zo of the signal transmission connection VER or vice versa - see, for example: “Dieter Da lmeyer; Theory of time domain reflectometry TeÜ 1, 2; electronics industry 2- 2001; 3-2001 ".
