Definitions

• the present invention relates to methods and devices for securing goods against theft according to the preambles of the independent claims.
• Devices for securing goods against theft which have a receiver, the receiver being in permanent operation, so that the security part has a high power consumption, which is undesirable, in particular, in the case of battery-operated security parts.
• known devices have the disadvantage that, for example, when several fuse parts are operated with a common central unit, a laborious selection of a special fuse part to be controlled next is required, for example by appropriate input by an operator, before the special fuse part can be activated.
• the object of the present invention is to provide methods and devices for securing goods against theft in such a way that operation and handling are simplified and the operating time is increased.
• the device according to the invention can, on the one hand, be a securing part which is operated as a so-called "stand-alone securing part".
• a further, corresponding securing part is therefore required for each additional item.
• the security parts of the different goods are independent of each other.
• the features according to the invention relate to a single securing part of this type.
• the device according to the invention can be a central unit with a plurality of security parts that can be connected to it.
• each of the securing parts can be assigned to a product, so that a plurality of products can be monitored simultaneously with this device according to the invention.
• the features according to the invention relate to the central unit.
• the activation of the receiver according to the invention in the switched-on state enables the device according to the invention to be controlled, for example, by applying a transmitter or so-called selection signals emitted by the transmitter after the device is switched on. It is thus possible for the device according to the invention to be put into the connection mode in a targeted manner by an operator the device in the connection mode can then be prepared for a transition to the monitoring state.
• the receiver When changing over to the connection mode, the receiver is switched off according to one variant of the invention and consequently absorbs no or only very little energy.
• the operator can take the necessary measures to prepare the device for the monitoring state, that is to say ultimately to "arm" it. This can be done, for example, by attaching a security part to the goods, the damage or disconnection of which, in the monitored state of the device, leads to a transition to the alarm state.
• a holding part of the securing part is attached to the goods, with monitoring of the holding part for proper attachment to the goods being activated.
• the device according to the invention is continuously checked to determine whether the holding part is properly attached to the goods. If the holding part is attached to the goods within the predeterminable waiting time, the monitoring is activated without the device being set in an alarm beforehand. This represents the normal operating sequence when a holding part is connected to the goods. If the holding part is not fastened to the goods within the predefinable waiting time and the monitoring is thus activated, the device according to the invention is, as already mentioned, set in alarm. As mentioned, this makes it easier to identify holding parts that have not yet been attached to the goods.
• the device In the event of an attempted theft, the device is switched from the monitored state to the alarm state.
• the features that the receiver is deactivated in the connection mode or in the monitoring state result in a reduction in the power or energy consumption of the devices according to the invention, so that the operating time of the devices is increased.
• a device according to the invention cannot be influenced by any signals as soon as it has deactivated its receiver in the connection mode or in the monitoring state. A fault in a device according to the invention due to incorrect reception of signals is thus ruled out.
• the monitoring state usually represents the state in which the device is in most of the time. In the alarm state however, the receiver is activated. This alarm state, however, takes up a considerably shorter period of time than the monitoring state. This also reduces the energy consumption of the device according to the invention.
• the device according to the invention can be operated by the operator via the receiver in this alarm state.
• the alarm state is ended when the receiver is acted upon by a transmitter.
• the receiver is activated during the transition from the monitoring state to the alarm state.
• signals which are emitted by the transmitter can be received by those devices which are in their alarm state and whose receiver is thus activated.
• selection signals the alarm state can then be ended and the device according to the invention can be correctly arranged on the goods again, for example after an attempted theft.
• the operator therefore does not have to laboriously select the device that is in the alarm state, for example by making a corresponding entry, but the operator can only end the alarm state by actuating the transmitter. Since only the receiver of the device in the alarm state is activated, only this device is influenced. All other devices remain unaffected, which is synonymous with the aforementioned automatic selection of the device which is in the alarm state. Obviously, this represents a significant simplification of the operation of the device according to the invention. The same also applies if several Devices according to the invention are in their alarm state.
• each of the transmitters can have a different coded selection signal.
• groups of devices according to the invention each of which is assigned to the same transmitter.
• Such groups can be a group of related "stand-alone security parts" or a group of related central units, in the second case, as already mentioned, a plurality of security parts can be connected to each of the central units.
• the device according to the invention does not end the alarm state if a selection signal received during the alarm is different from the selection signal received after switching on. This ensures that the same transmitter or the same selection signal must be used to end the alarm state of a device as after the device was switched on.
• the device according to the invention can preferably be switched off by switching off a power supply to the fuse part. When the device is switched off, a selection signal received beforehand, ie after the device is switched on, is lost because the selection signal is stored in the receiver of the device in a volatile memory, for example in a so-called random access memory (RAM). In this way, when the device is switched on again, a new selection signal can be transmitted to the device according to the invention, which in turn is stored in the volatile memory until the device is switched off again.
• RAM random access memory
• the invention provides for a selection signal to be transmitted from one transmitter to at least one further transmitter, so that selection signals, including coded selection signals, can be copied to a plurality of transmitters. This results, for example, in the possibility that different operators can simultaneously receive control over a specific group of devices according to the invention.
• optical and / or acoustic signal transmitters can be used, which are provided in the security part or in the central unit. Due to their low power consumption, light-emitting diodes as optical signal transmitters and piezo sound transducers as acoustic signal transmitters are particularly favorable. In the invention, these signal transmitters are used, for example, to indicate an alarm state and thus an alarm.
• An advantageous embodiment of the invention provides for the signal transmitters to be arranged in the interior of the device according to the invention, a housing being at least partially translucent or is transparent, so that the optical signal generated by the light-emitting diode can also be perceived well outside the security part or the central unit.
• a translucent housing or translucent housing sections of the device are particularly advantageous here because the signal effect of the optical signal is further increased by scattering effects on the translucent housing parts usually formed from plastic.
• a further advantageous embodiment of the method according to the invention provides that the optical and / or acoustic signal modulates depending on the remaining waiting time, i.e. for example, its intensity or frequency is changed. Such a modulation allows an operator to estimate the remaining waiting time in a simple manner and, in particular, to adapt their work processes when configuring the device according to the invention to the remaining waiting time.
• a particularly simple handling of the device according to the invention is given in a further variant, in which the selection signal is transmitted from the transmitter to the receiver by means of a remote control.
• a remote control In principle, it is possible to use optical remote controls, e.g. Use infrared-based remote controls. Radio remote controls, however, allow an even simpler handling of the invention, since a direct line of sight between the transmitter of the radio remote control and the receiver located in the device according to the invention is not required.
• Another advantageous embodiment of the method according to the invention provides that a state of the energy supply of the device according to the invention is monitored.
• a state of the energy supply of the device according to the invention is monitored.
• a further advantageous embodiment of the invention proposes that the transmitter selectively transmits one of a plurality of predefinable selection signals, which in turn codes could be.
• An operator can select the desired selection signal, for example, by means of a switch attached to the remote control.
• Another variant of the invention provides that when a holding part is fastened to the goods and / or when a fastening part is fastened to a preferably theft-proof fastening point, the monitoring is activated by closing a measuring loop formed by sensor means in the holding part or in the fastening part.
• Another variant of the invention is characterized in that • the securing part, in particular the holding part, can be connected to the central unit via the connecting means, and that when the securing part is connected to the central unit, monitoring for proper connection of the securing part and the central unit is activated.

• a maximum waiting time can be specified, within which at least one channel of the central unit 10 must be connected to a security part 1.
• the central unit 10 then changes to the monitoring state 130.
• the central unit 10 If one of the goods 200 to be secured is now detached from the associated holding part 2 or if one of the connecting cables 4 is cut or one of the connecting cables 4 is pulled out of the central unit 10, this results in a transition of the central unit 10 to the alarm state 120.
• an alarm is given via the optical and / or acoustic alarm means 7a, 7b.
• the receiver 6 of the central unit 10 is activated, so that the alarming can be switched off by retransmitting the selection signal from the transmitter 5 to the receiver 6 and the state 180 can be entered.
• the overall security method of FIG. 4 in FIG. 5 is related to the central unit 10.
• the alarming in the alarm state 120 therefore relates to the central unit 10 in FIG. 5, but not to a specific security part of the plurality of security parts 1 which are connected to the central unit 10. Which of the security parts 1 connected to the central unit 10 has actually triggered the alarm can only be determined from the light-emitting diodes 11 assigned to the individual channels.
• the central unit 10 contains a further circuit or the like, by means of which the light-emitting diode 11 is used for display an alarm is switched on, in the associated security part 1 of which an alarm-triggering process (separation of the goods 200 from the holding part and / or interruption of the connecting cable 4) has taken place.
• the arrangement according to FIG. 5 can preferably be used if a plurality of central units 10 are present, each of which in turn has a plurality of securing parts 1 are connected.
• the plurality of central units 10 can be used by different operators through different selection signals.
• Several central units 10 can be assigned to a single operator as a group. If an alarm is triggered by one of the large number of security parts 1, only the operator who is responsible for the associated central unit 10 to which the alarm triggering security part 1 is connected can end the alarm. The operator can then use the light-emitting diodes 11 to recognize exactly which of the security parts 1 connected to the central unit 10 has triggered the alarm.
