Definitions

  • the invention relates to a device for monitoring things and / or people according to the preamble of claim 1.
  • resonator marks which are attached to the object to be secured in each case and contain an oscillating circuit which, when the object is brought through a so-called lock, disturbs an RF field generated at this location, whereupon an alarm is triggered.
  • a shoplifter manages to remove the tag from the item to be secured before going through the lock, the theft cannot be detected.
  • An electronic monitoring system using security tags or tags with increased functional capabilities is known from GB-A-2 181 326.
  • signals with various message contents are transmitted from a transmission device to the fuse tags, and are decoded in the fuse tags. If the signals fail to appear or the fuse tags are removed, an alarm device in the fuse tag is activated by a signal processor, unless an alarm triggering is previously prevented by a correspondingly coded transmission signal.
  • an electronic circuit of a transmitter for emitting a coded RF signal comprises a divider, via which the alarm signal is routed such that an alarm is only triggered if one corresponds to the partial ratio of the divider Number of alarm signals was received.
  • This design of the device ensures, on the one hand, increased interference immunity compared to the conventional system of the type mentioned at the outset, which always emits an acoustic alarm when it reaches outside the area in which an uncoded HF field is generated. It is now no longer possible even for technically adept long fingers to mute the device with the aid of a simple transmitter, since an alarm is emitted in the same way when an uncoded or incorrectly coded HF signal is present as in the absence of any HF signal. If the device is designed in such a way that an alarm is emitted when a specific signal is present, the interference immunity to external influences is also significantly increased in this case. For example, it cannot happen that all objects provided with the devices in a toy department of a department store give the alarm when a radio-controlled toy car is presented to a customer.
  • the coding can "individualize” the visitor. Is the Device designed so that it emits an alarm when it receives a signal with a certain code, so you can set up transmitters in the areas that should not be entered by the visitor, which emit this code. There are z. B. also easily conceivable different "levels” which can be defined overlapping one another within a factory site using RF transmitters which emit different types of codes. Depending on the classification of the visitor, the visitor then receives a device with a decoder which issues an alarm when a certain, possibly also different, code is present (in an OR link).
  • this design and use of the device as a visitor badge not only enables visitors to be monitored, but also, for. B. also an automatic "pilot" of the visitor z. B. by a larger site, which is divided by transmitters with different codes in "grid squares".
  • the device designed in this way can also be used advantageously as an anti-theft device.
  • a department store with 3 floors you can e.g. B. assign a special code to each floor, to which all security marks are set with which the objects on this floor are provided.
  • the coders of the HF transmitters are then set so that each floor is provided with transmitters that build up corresponding HF fields, but the code which triggers an alarm is not emitted on the floor in question. This triggers an alarm when a secured item is moved from one floor to the other.
  • an RF field with appropriate coding must be present in order to keep a security mark mute.
  • the device is advantageously designed in such a way that once an alarm has been triggered, it continues to be emitted until the device receives an RF signal which is modulated with a second code, which leads to the alarm being switched off.
  • the associated RF transmitters are preferably designed as handheld devices, the z. B. every department store detective carries with him.
  • the safety of the devices in question are further determined by the life of the battery used. Since the housing of the devices must of course not exceed a certain maximum and the costs for large batteries are higher than for small batteries, only a limited operating time of the devices is possible. After the battery has tired, an alarm is no longer triggered. If the operating time of the devices with a battery set is very short, the statistical probability of a used battery is higher than for devices with a longer operating time. To solve this problem, the invention proposes to provide a clock in the device, which at defined intervals, for. B. once per second, emits switch-on signals which "awaken" the remaining active parts of the device by their power supply is turned on while these active parts "sleep" between these signals.
  • the duration of the "wake-up phase” is preferably chosen to be longer for the HF alarm part than for the monitoring of the security element, since during the wake-up phase at least one complete code signal consisting of several bits must be received in any case, while for the monitoring of the conductive security element, so to speak a single bit is sufficient.
  • the device z. B. operate in a 1: 9 ratio between active and "sleeping" state, which leads to considerable power savings and thus to a significant extension of the life of the battery.
  • a clock signal for the decoder can be generated via the clock generator if the clock generator (which preferably contains a crystal oscillator) is synchronized with the received HF code signals.
  • the radiated alarm can be either an acoustic signal or an RF signal, e.g. B. alarms the department store detective via a transmitter located at this. It is advantageous here if the emitted RF signal is coded, since this code then z. B. can be selected specifically for the object provided with the security mark. The department store detective then knows e.g. B. that just a secured part from the jewelry or leather goods department or ... was stolen. Of course, it is also possible to combine both types of alarm.
  • coded RF signals of an RF transmitter 10 shown in FIG. 3, which comprises an antenna 13, a transmitter 12 and an encoder 11, are received by the security tag 15 via an antenna 17 and fed to an RF receiver 16 , which converts the signals via passive components (LC parallel resonant circuit with downstream demodulator and final pulse shaper) into signals that are "understood" by digital circuits.
  • the digital signals obtained in this way arrive in the decoder 20, specifically there in a serial-parallel converter 21 which always reads in a complete code word.
  • the stored code word is parallel to both a comparator 22 with coding switch 23 for triggering an alarm, and a further comparator 22 'with another Coding switch 23 'supplied.
  • the comparison signal from the comparator 22 ("1" if there is a match, "0" if there are different code words) is fed to the input of a divider 25 which divides by two in the embodiment shown.
  • This divider 25 now ensures that a signal is only present at the terminal Al of the decoder 20 which triggers an alarm if the alarm code has been detected twice. This provides increased security against false alarms, whereby the division ratio can of course be increased to increase redundancy and thus to increase interference immunity.
  • the further comparator 22 ' is followed by such a divider.
  • the output of the divider 25 leads via the terminal A1 of the decoder 20 to the non-inverting input of an OR gate 24.
  • the other, inverting input of the OR gate 24 is led to a logic "1" via a fuse element 14, a wire.
  • the security mark 15 is attached to the object to be protected.
  • the output of the OR gate 24 is connected, on the input Res the output of the further comparator 22 'via the terminal Res of the decoder 20.
  • the alarm memory 31 has an erase input Res, which with an output terminal of the further comparator 22 'is connected and via which a once triggered alarm can be stopped.
  • the delete code (which is stored in the coding switch 23 ') is emitted by a - not shown - handheld transmitter, the z. B. carries the department store detective with him.
  • the output of the alarm memory 31 leads to the input of a tone generator 32, which at the same time contains a driver which controls a sound transducer 33 (preferably a piezo sound transducer). The arrangement is such that a sound with a defined sound is emitted when an output signal is present at the alarm memory 31.
  • an HF alarm transmitter 30 is provided, in which the output of the alarm memory 31 activates an HF alarm transmitter 34 which activates an emits an RF signal coded in an adjustable manner via an RF alarm encoder 35. This RF signal can then be received and identified in an alarm receiver, not shown.
  • the coding switches 23 and 23 'and the coders 11 and 35 are preferably at least partially adjustable, so that at least every customer or device receives a special code. Furthermore, as indicated at the beginning, can be goods or person-specific Brands 15 are produced without major conversions or design changes being necessary.
  • a reduction in the construction effort can be achieved by using a single coding switch 23 for the first comparator 22 and the second comparator 22 '(for resetting), as shown in FIG. 4, so that the customer-specific setting of the alarm code also simultaneously Deletion code is changed customer-specifically.
  • the arrangement is simplified in that only part of the information in the alarm code as well as in the delete code can be set, which is accomplished in the embodiment of the invention shown in FIG. 4 by only bits 4, 7, 11 and 15 being assigned to the (Four-digit) coding switches 23 are guided, while the remaining 16 bits are at defined, not subsequently changeable logic levels.
  • the coding switch 23 can be designed to reduce costs in the form of short-circuit plugs in a manner known per se.
  • a pull-up resistor 27 is provided between the input of an inverter 26 and the positive logic level (here V CC ), the output of the inverter 26 being at the inverting input of the OR gate 24.
  • the input of the inverter 26 is still on the fuse element 14 on one end of the inductor 18 (ferrocup), the other terminal of which is connected to ground. If the fuse element 14 is severed, so the input of the inverter 26 is pulled to a positive level, so that a "0" is present at the output of the inverter 26 and an alarm is given (via the inverting input of the OR gate 24).
  • the securing element is designed as a coaxial cable, the outer sheath 17 of which is led to the antenna input of the RF receiver 16.
  • a short circuit of the received RF power is avoided by the inductance 18.
  • this arrangement ensures that the (technically experienced) long finger cannot simply detach the antenna of the security tag in order to prevent an HF alarm being triggered.
  • a two-wire line can also be used here (preferably with a small distance between the wires), with the advantage that a relatively long antenna can be produced in a mechanically simple manner.
  • FIG. 6 A further, particularly preferred embodiment of the invention is described below with reference to FIG. 6, which initially differs from the previously described embodiments in that the alarm memory 31 comprises two cross-coupled manatches 37, 38, so that an alarm which has been triggered once lasts for so long remains until a reset signal is output at terminal RES of decoder 20.
  • a clock generator 40 is provided which contains a quartz oscillator 41 with a divider 42 connected downstream. The reset input of the divider 42 is routed via a synchronization circuit 19 to the output of the RF receiver 16, so that when a coded RF signal is received the clock generator 40 is synchronized with the transmitted code.
  • the clock generator 40 generates a clock pulse which is supplied to the decoder 20 in a manner known per se. Furthermore, two electrical switches (FET) 43 and 44 are controlled via the counter 42, which the output voltage of the battery 45, z. B. once every second, for defined periods of time at outputs A and B of the clock generator 40. In the embodiment of the invention shown in FIG. 6, the battery voltage is longer at point A than at point B.
  • the supply connections V CC of the components provided in the clock generator 40 are also permanently connected to the battery 45, as is the power supply input V CC of the alarm memory 31.
  • the power supply input V CC of the tone generator / driver 32 is fed via a FET 36 to the continuous power supply, the gate of which -Connection to the output of the alarm memory 31. If an alarm is triggered, the tone generator / driver 32 is supplied with current, otherwise it is disconnected from the battery 45.
  • the power supply input V CC of the decoder 20 is connected to terminal A of the clock generator 40, as is that of the OR gate 24.
  • the pull-up resistor 27, like the power supply terminal of the inverter 26, is at point B. This ensures that the The power supply for the active components of the arrangement is only switched on in cycles (for example, once per second) for the minimum time required to detect an alarm signal or to cut the fuse element 14.
  • a switch 29 is provided in addition to the fuse element 14 in an otherwise identical arrangement as the fuse element 14, a pull-up resistor 28 being provided here.
  • the switch 29 is arranged in the housing (not shown) such that it is also closed when the housing is closed. If a long finger opens the housing (e.g. to remove the battery), an alarm is given.
  • a counter 39 is provided, the reset input of which is connected to the RES terminal of the decoder 20 (for example according to FIGS. 1 or 4) and the count input (count) of which is at point A of the clock generator 40 .
  • the supply connection V CC is continuously connected to the battery 45.
  • the output of the counter 39 at which a logical "1" appears when the counter overflows, is connected to a further input of the OR gate 24.
  • the clock generator 40 can be designed such that it emits either a periodic clock signal or a clock signal with a randomly controlled clock interval and controls the electronic switches 43 and 44 and thus also the outputs A and B accordingly.
