Definitions
- the invention relates to a device for identification by people participating in sporting competitions or Animals according to the preamble of claim 1.
- the random code emitted by the club antenna can be via a receiver on the transmission frequency of the club antenna is tuned, for example received and recorded at 125 kHz become.
- the identity codes knowing their homing pigeons, it is for a homing pigeon fancier only necessary to determine the order in which his racing pigeons on the club antenna be performed. It is then possible for him to use the identity codes assign the random code assigned in each case. He can do this Then enter the data in his registration device and thus one simulate the earlier arrival time of his pigeons. This manipulation is against the background of high stakes in racing pigeon races to see.
- the known solution also requires another transmitter and a signal generator.
- the read / write device can be coupled to the further transmitter, so that this transmitter when reading out the memory of the transponder is switched off, otherwise it will be the much smaller ones Field strength fluctuations in reading operation in comparison would interfere with broadcasting.
- the invention has for its object a device to identify those taking part in sporting competitions To improve people or animals in such a way that the security against eavesdropping without disturbing the Data exchange between read / write device and transponder is improved.
- the emitters are Antenna arrangement in the invention supplied the same transmission signal. This means that no external signals are generated be the data transfer from read / write device to could affect transponders. This applies to both Case that the information in the pulses, in the pauses, combined in the pulses and the breaks or in one analog modulation of the carrier. Since it's the same thing Transmitted signal, there is necessarily synchronicity between the signals emitted by the beams, so that they are mutually distant in the far field with the appropriate phase position can effectively wipe out. With “delete” is here such attenuation means that the signal in the far field below of the usual interference level and noise, so that it can no longer be read. The phase position is there rigid so that the damping is stable.
- Another advantage of the invention is that it not only when describing the transponder, but also is effective in the control reading.
- the emitters can be designed so that amplify their field components in the resulting near field. This allows for safe energy transfer and data transfer from the read / write device to the transponder necessary transmission power compared to the operating case with only one Antenna can be reduced.
- the radiators preferably comprise coils or coil areas, which are arranged side by side and fed in opposite phases are.
- the coils or coil areas can also be axially parallel be arranged.
- the coils or Coil areas in a common, transverse to the coil axis level.
- the emitters have a common coil on, in two, together forming an 8 Coil areas are formed. Because the two coil areas are originally formed from a common coil, is a similar structure and therefore an optimal symmetry guaranteed. Manufacturing is also simplified and avoided electrical contacts since the two coil areas are necessarily galvanically connected to each other.
- the coils or coil areas can be surrounded by a housing be that inside one of the coils or coil areas has moved in. There can be a spatially defined one Programming field for reliable electromagnetic coupling formed when immersing a transponder be.
- the spotlight arrangement comprises two coil areas 10, 12, which are arranged side by side and aligned axially and in a common, plane extending transversely to the coil axes 14, 16 18 lie.
- the coil areas 10, 12 are out of phase with fed the transmission signal. This leads to the magnetic Field components of the electromagnetic field the cross sections of both coil areas 10, 12 and form closed field lines 24. This means that the field strength in the near field of the coil regions 10, 12 is increased, while the field line density is simultaneously in the far field decreases sharply, i.e. a strong attenuation of the transmission signal in the Fernfeld enters.
- the radiators form a common coil, which in two, together forming an 8 Coil areas 10, 12 is formed.
- the coil areas 10, 12 are thereby mirror-symmetrically shaped and poled in opposite phase at the same time when the electrical in series switched coil areas 10, 12 to the read / write device be connected.
- the two coil areas 10, 12 are of a common one Surround housing 20, which has a constriction, which in the inside of one coil area 10 is drawn in.
- This Constriction forms a spatially defined programming field there 22, allowing reliable electromagnetic Coupling when a transponder is immersed in the constriction becomes. This prevents a possible incomplete data transfer takes place when the transponder when approaching or moving away from the programming field 22 is moved along the other coil area 12.
