Definitions
- Theft detection device Theft detection device
- the invention relates to a device consisting of at least two components for determining whether an object, in particular a vehicle, which is connected to one of the two components, has been stolen or not.
- Such devices are known for example to prevent shoplifting.
- One component is fastened to a hidden place on the goods and, when crossing an invisible electronic lock in the area of the shop exit, activates an alarm system which indicates that someone is trying to leave the shop with a product at which such a component is attached.
- DE-OS 40 03 280 provides that the authorized user of a motor vehicle with a mobile transponder conducts a dialog with a stationary transponder in the motor vehicle and thus proves his authorization to open and start the motor vehicle.
- the US-PS 4 682 062 has a similar system to the content, but which is only installed inside the motor vehicle, so that security against eavesdropping is given.
- DE-OS 36 05 697 proposes to store important vehicle-related data in vehicles with diagnostic electronics and in police controls, border crossings or visits to the workshop, to query these data and to compare or determine them with a list of vehicles reported as stolen whether the approval numbers match the stored matches, etc.
- DE-OS 32 25 506 suggests installing radio transmitters in vehicles, which are activated when unauthorized start-up is used and are aimed and localized by direction finder transmitters.
- the stationary unit emits a message
- the movable unit is thereby activated and emits its identification signal, which is checked and evaluated by the stationary unit.
- the invention aims to in the course of routine checks to recognize vehicles, even without having to stop them, which have a special anti-theft device on board and to determine the legality of use when checking these vehicles.
- a passive transponder is present in the vehicle which, after receiving an activation signal which is periodically emitted by a checking station, sends an encrypted response which is checked by the checking unit for its validity, that if the answer is valid, the The driver is prompted to issue a code corresponding to the transponder arranged in the vehicle, which in turn is checked for validity by the checking unit and that the result and, if appropriate, the progress of the checking is displayed on a display unit.
- FIG. 1 shows a functional overview
- FIG. 2 shows a block diagram of the vehicle transponder
- FIG. 3 shows a block diagram of the user transponder
- FIG. 4 shows a block diagram of the checking unit including the output unit.
- Hidden in a car is a vehicle transponder, which is activated by a radio signal from a police car inspection unit and which identifies a vehicle. radiation emits. This causes the checking unit to send a request for handlebar identification, which can be answered in various ways, for example by a handlebar transponder that transmits a predetermined code fully automatically or activated by the handlebar.
- the vehicle transponder hidden in the vehicle consists of a receiving antenna 1, a receiver 2 and a microprocessor 3. Furthermore, the vehicle transponder comprises a transmission part, which will be described later.
- the receiver 2 receives a signal received by the receiving antenna 1, it sends this to the microprocessor 3 for further evaluation. If the microprocessor 3 determines that the received signal is a valid activation signal, it activates a switch 4, through which the transmitter part of the vehicle transponder is supplied with electrical current.
- the transmission part consists of a generator 7, a modulator 5, a transmission amplifier 6 and a transmission antenna 8.
- the microprocessor 3 can transmit its encrypted identification code in response to the activation code via these transmission modules.
- the vehicle transponder then returns to the inactive state, that is to say that the switch 4 disconnects the transmitter part from the supply 9. Since, for safety reasons, the vehicle transponder has no connection to the vehicle's electrical system, that is to say it works completely autonomously, switching off the power level leads to a minimization of the power consumption and an extension of the intervals between battery replacement and recharging. It is entirely possible to provide an energy supply that works over the entire expected lifespan of the transponder. If the microprocessor 3 determines, when checking the received signal, that it is not a valid activation signal, the switch 4 remains in its interrupted position and the transmitting part remains completely passive.
- a microprocessor 15 transmits periodically or by the user via a transmitting part, which consists of a generator 16, a modulator 17, a transmitting amplifier 18 and a transmitting antenna 19 lets out an encrypted, preferably non-repeating, activation code.
- a vehicle transponder within the scope of the checking unit, this is activated and emits its special identification code.
- an identification code is received by a receiving antenna 11 and passed on to the microprocessor 15 via a receiver 12 for decryption and checking. If the processor determines that a valid code is present, the user of the vehicle is asked to identify himself.
- This request can be made in different ways. If, for example, the user transponder according to the block diagram of FIG. 3 is used, the user does not notice anything of the check if he carries this transponder with him, as intended.
- This transponder is constructed analogously to the vehicle transponder, so that only its presence in the vehicle is checked by the checking unit.
- the user transponder when activated, emits an optical and / or acoustic signal and thus requests its owner to activate it. It can also be provided, but because of the longer duration of the check, it is not preferred that the user has to enter the code personally, for example via a keyboard of the check unit, or for example the code that is magnetically stored on a part similar to a credit card. by swiping this card through an identification station of the checking unit.
- a variant consists of a card on which the code is stored electronically and is emitted electromagnetically, which enables control over a certain distance, possibly up to a few meters, which simplifies and accelerates the check.
- this request can also be a neon sign in the area of the checkpoint.
- the signal emitted by the user transponder described further below also reaches the microprocessor 15 via a receiving antenna 13 and a receiver 14 and is evaluated by it. If this check reveals that the vehicle identification received previously and the user identification correspond, it can be assumed that the vehicle was put into operation by an authorized user.
- the checking unit does not receive a response signal from the user unit or a valid signal, ie, one that corresponds to the vehicle identification, within a predetermined time, the user of the checking unit becomes acoustically and / or optically aware of this communicated via a display unit 20, thus enabling targeted vehicle or driver control.
- FIG. 3 An example of a user transponder is shown schematically in the block diagram in FIG. 3. It has a receiving antenna 26, an associated receiver 27 and a microprocessor 21. If the microprocessor determines that it has been requested to do so by a valid signal, it automatically sends an identification signal to a transmission antenna 25 via a generator 23, a modulator 22 and a transmission amplifier 6.
- the delivery of this signal may be linked to the actuation of a push button 28 by the user, and the manner in which the user is prompted to deliver the signal was described above.
- the user transponder is preferably in a very compact form as a key fob or similar. designed.
- the type of coding is known from similar fields of application, a wide variety of methods can be used to make it difficult to intercept and decipher the code, in particular it is possible to use one-time codes in which the information in the structure of the code, so that no repetitions of the actually transmitted sequences occur.
