Definitions

  • the invention relates to a method for securing and managing movable objects according to claim 1 and to an object security and management system according to claim 21.
  • a transmitting device is set up at the exit of a room to be monitored.
  • Each object to be protected contains a receiving device with a resonance circuit which is tuned to the transmission frequency of the transmitting device. If the secured object reaches the radiation area of the transmitting device, a voltage source integrated in the receiving device is activated and an acoustic alarm is triggered.
  • a voltage source integrated in the receiving device is activated and an acoustic alarm is triggered.
  • you leave the room outside the range of the transmitter for example through a window or an unsecured side entrance, an alarm will not be given.
  • the safety device is therefore relatively easy to bypass.
  • DE-A1-44 17 882 proposes to provide it with an open resonant circuit in the form of a printed circuit.
  • An in the out Alarm area arranged in the corridor area has a transmitter and a receiver, which are alternately put into operation. If the security sticker comes into the range of the alarm transmitter, a natural vibration is generated in the open resonant circuit. As soon as this is detected by the receiver of the alarm transmitter, this triggers an acoustic or visual alarm.
  • the relatively short range of the safety device is also problematic here. If an object has left the secured zone, it can no longer be tracked despite the alarm.
  • DE-A1-195 12 045 describes a wireless anti-theft alarm device for securing transportable objects.
  • a signal transmitter attached to the object to be secured is connected to a receiver via a radio link. The latter is carried by the user.
  • the signal transmitter triggers an alarm signal which is intended to identify the thief.
  • the disadvantage here is that the signal transmitter must permanently emit a signal in order to maintain contact with the receiver. This leads to a high power consumption, which has to be applied by batteries or rechargeable batteries that have to be constantly replaced.
  • tracking of the stolen item is only possible to a limited extent, because the alarm is only triggered when the item has already been stolen.
  • An acoustic alarm signal is also difficult to locate in a noisy environment.
  • a security method known from DE-A1-195 28 818 has the same disadvantages.
  • a radio signal emanates from an object to be secured, which triggers an acoustic alarm when an area is defined by the range of the transmission signal at an assigned mobile receiver.
  • the transmitter is only activated when the object is moved, for example by an integrated inclination sensor. This does reduce electricity consumption.
  • Another disadvantage, however, is that each transmitter must be explicitly assigned a receiver, i.e. Securing several objects can only be achieved with the corresponding effort. If the receiver is moved or if it is outside the audible range of the alarm signal, the security system loses its effectiveness. Difficulties also arise in differentiating the alarm signals of different objects, which are difficult to assign to several receivers.
  • EP-A1-0 840 265 provides a synchronized transmit / receive system for monitoring several objects with only a single receiver station.
  • the one a transmitter to be monitored sends a defined pulse signal at regular intervals, which is detected by a synchronously activated receiver. If the pulse signal fails to appear due to an excessive distance from the receiver or if the pulse signal arrives late at the receiver, the receiver triggers an acoustic or tactile alarm.
  • the transmitter can also be activated by other electrical devices, for example a cell phone or a button integrated in the transmitter, for example to signal the receiver of an emergency situation. If several objects are secured, each transmitter sends out a different pulse signal.
  • the receiver is activated and deactivated in synchronism with all pulse signals.
  • EP-A1-0 768 629 also enables a large number of objects to be secured.
  • a central monitoring unit equipped with an ultrasound receiver and a high-frequency transmitter sends out a coded high-frequency signal every 2 to 3 seconds, a separate, frequency-modulated signal being provided for each object to be monitored.
  • Each item is provided with a security unit. This receives the high-frequency signal and compares the coding with a signal code stored in a memory. If the signal is recognized, the security unit sends a frequency-modulated ultrasound signal back to the monitoring unit. If the object is within a predefined distance from the monitoring unit, the monitoring unit can record and recognize the ultrasound signal.
  • an acoustic alarm is triggered which informs the owner of the item that it has been removed without authorization.
  • an alarm signal is only received when an object has already been removed. However, it is usually too late for tracking, especially since the object would first have to be identified using the alarm signal, which is only possible to a limited extent.
  • the aim of the invention is to overcome these and other disadvantages of the prior art and to create a method for securing any number of movable objects, wherein individual objects can not only be identified, but can also be localized and / or tracked at any time. Unauthorized access to one Object should be recognized early so that countermeasures can be taken in good time. In addition, it should also be possible to manage the secured objects.
  • An object security and management system for performing the method should be easy to use and should be freely configurable.
  • the aim is to optimally secure any number of objects against unauthorized removal, handling or theft.
  • the system is also intended to offer expansion or change options in order to adapt to changing situations. Early alarm triggering, possibly in several stages, is just as desirable as high operational reliability and flexibility with low energy consumption.
  • each security unit is assigned a freely programmable identity code which represents the object to be secured or monitored in each case. Furthermore, the security units are assigned individually and / or in groups to at least one monitoring unit, each security unit being activated when the assigned object is unauthorized to use and emitting a signal modulated in accordance with the identity code, which is detected by at least one monitoring unit and fed to an evaluation and operating unit which triggers a programmable action based on the transmission of the signal and / or on the basis of a property of the signal.
  • the monitoring unit receives the signals from the fuse units assigned to it and forwards them to the evaluation and operating unit.
  • the latter can - for example with the help of suitable software - manage almost any number of security units and - depending on the need and application - can trigger an individual action, for example a silent or acoustic alarm.
  • the method is extremely flexible, since one or more security units can each be assigned to a monitoring unit. Changes or extensions are also possible at any time. It can be Monitor several separate rooms as well as entire groups of goods or objects individually and independently of each other. If several monitoring units are used, spatial movements of the security units can also be detected so that the objects to be secured can be tracked via the evaluation and operating unit.
  • Another advantage is that the security units are only activated if an unauthorized handling of an object takes place. As a result, the energy consumption of the fuse units is extremely low, which has a favorable effect on their service life. Furthermore, the security units can always be reused by simply assigning a new identity code when changing from one product to another.
  • the identity code is created by means of the evaluation and operating unit, transmitted to the relevant security unit via a monitoring unit and stored in a retrievable manner.
  • the assignment of an identity code to a security unit is preferably carried out via a further programmable identity code, which is stored in the relevant security unit.
  • the ease of use achieved thereby facilitates and accelerates the assignment of the individual fuse units.
  • It is also possible to manage the secured items by querying the identity codes from the security units at regular intervals - for example for the purpose of an inventory.
  • the evaluation and control unit compares the answers received with the expected signals and creates e.g. an inventory list. Additional information and / or data relating to the object to be monitored can be assigned to each identity code, which expands the area of application accordingly.
  • the identity codes of the security units assigned to a monitoring unit can be stored in the relevant monitoring unit. At the same time, further data or information can be stored, for example information about the location of the monitoring unit or criteria for triggering or activating an action. This ensures a high level of operational safety at all times, since an alarm function can also be triggered if the evaluation and control unit fails. Data security is also extremely high, since any information that may be required cannot be lost.
  • the assignment of the security units to a monitoring unit takes place via a third programmable identity code, which is also stored in the relevant monitoring unit.
  • a further embodiment of the invention ensures a high degree of security for the objects to be monitored, in that the security unit is activated by touch, movement and / or change in position. Just touching or lifting goods is enough to activate the monitoring process. Thefts or unauthorized events are immediately recorded so that appropriate countermeasures can be prepared or initiated.
  • the property of the modulated signal that triggers a programmable action is preferably a predetermined signal strength and / or signal delay. This enables simple room monitoring, for example. As soon as an object moves away from its assigned monitoring unit in such a way that the modulated signal can no longer be received, an action is triggered automatically. It is irrelevant in which way the object leaves the secured area. The use of multiple monitoring units can expand the secured area or allow tracking of an object.
  • the programmable action is preferably a silent, acoustic, optical and / or tactile alarm which is generated on the security unit, on the monitoring unit and / or on the evaluation and operating unit.
  • Another embodiment of the method according to the invention provides that the programmable action activates a room monitoring device, for example a camera or motion detector, so that the object concerned can be observed from a central monitoring station or a security center.
  • a room monitoring device for example a camera or motion detector
  • the programmable action can identify the object, the evaluation and operating unit for each security unit, which emits a modulated signal in accordance with the programmed identity code, indicating and / or a location description, for example a site plan, of the assigned object and / or issues.
  • a modulated signal in accordance with the programmed identity code, indicating and / or a location description, for example a site plan, of the assigned object and / or issues.
  • At least three monitoring units are assigned to a security unit, which record the signal generated by the security unit. Differences in the signal strength, the field strength and / or the signal transit time at the individual monitoring units enable the calculation of a movement of the object in question. In addition, its direction and speed of movement can be recorded.
  • the calculations required for this are preferably carried out by the evaluation and operating unit or a software stored therein. It is expedient if the evaluation and operating unit of each security unit, which emits a modulated signal in accordance with the programmed identity code, displays and / or outputs the current position and / or the direction of movement.
  • a monitor or an LCD display serves as the display device. In connection with the typing of the object, targeted countermeasures can be initiated immediately.
  • the signal emitted by the security unit and / or the monitoring unit is expediently a radio signal, which is preferably in the MHz range.
  • the signals can be sent intermittently. Changing operating frequencies (frequency hopping) increase the operational safety. This effectively prevents interference from outside.
  • the evaluation and control unit can query the presence of all or selected security units at predetermined time intervals.
  • the security units are activated via the monitoring units, so that the respectively stored signals are sent to the evaluation and operating unit, in particular in the form of a response signal.
  • the evaluation and control unit compares the incoming information, for example with a stored reference list, and carries out a comparison. If certain objects are missing or do not respond to the query carried out, a programmed action can be triggered, for example an alarm or a comparison of the information stored in the monitoring units.
  • the Memory of the monitoring units can be read out. At the same time, the storage data of the monitoring units can be updated.
  • Another aspect of the invention provides that a separate alarm is triggered when an unauthorized removal of the security unit from an object. This is important in order to prevent misuse of the fuse units.
  • the invention represents an essential further development also with regard to an object management and security system for the security and management of movable objects.
  • This is characterized by a modular structure with at least one programmable security unit which can be fixed to an object and which, in the event of unauthorized handling of the object in question, acts as a security unit emits identifying signal, with at least one monitoring unit, which detects the signal emitted by the security unit, and with an evaluation and operating unit, which receives the signal forwarded by the monitoring unit, and a programmable signal due to the transmission of the signal and / or due to a property of the signal Action triggers
  • any number of objects can be individually monitored and managed.
  • the transmitter units attached to the objects to be secured or monitored can be assigned individually or in groups to one or more monitoring units, which forwards the previously programmed signals to the evaluation and operating unit.
  • Any unauthorized handling of a secured object is immediately recorded and processed by the evaluation and control unit.
  • an individually programmable action can be triggered, for example a silent alarm when the object is touched or raised, followed by an acoustic alarm when the object leaves a predetermined area.
  • the transmitter units and the monitoring units can be combined as desired and configured via the central evaluation and control unit, whereby the variety of possible uses is extremely high.
  • An expansion or reduction of the number of security units can also be implemented at any time without any problems by forwarding the new assignments between security units and objects from the evaluation and operating units to the monitoring and security units.
  • the A security unit can be changed from one item to another.
  • objects can be secured as well as animals or people. The latter is of great use, for example, in hospitals, old people's homes or nursing homes. Machine or access security in industrial and private areas is also possible, whereby an existing system can be expanded at any time.

  • a ceiling camera 90 can be activated in order to be able to observe the process from the evaluation and operating unit 60. On the basis of the stored data, the latter also shows what the object is and in which department or in which room R1, R2 it is located.
  • three monitoring units 40 are provided for each room R1, R2.
  • Their transceivers 46 are designed such that, in addition to the identity code G-ID emitted by a security unit 30, they can also determine the signal transit time and / or the field strength of the associated radio signal.
  • These measurement data are forwarded to the evaluation and control unit 60 as a repeater via a central monitoring unit 50 (not shown in FIG. 5), possibly with intermediate storage in the monitoring units 40, which is based on the transit time or field strength differences and their changes a possible movement of the relevant security unit 30 and thus the associated object 20 calculated and displayed on the monitor 62.
  • the ID signal G-ID With the aid of the ID signal G-ID, the precise typing of the object 20 is possible, the assignment table 66 being able to provide further useful information.
  • objects 30 to be monitored can be tracked reliably within a room R1, R2 or — with an appropriate arrangement of the monitoring units 40, 50 — within an entire building and beyond, which is particularly advantageous in the case of objects 20 which are naturally frequently moved because, for example, it requires their use.
  • the evaluation and control unit 60 can immediately trigger a silent or acoustic alarm, for example to alert a detective or the security personnel. Based on the information on the object 20 displayed by the evaluation and operating unit, these can immediately take targeted countermeasures.
  • GSM modules 92 integrated in the security units 30 (see FIG. 6 in this regard). After their activation by the evaluation and control unit 60 and or the microprocessor 33, these transmit a corresponding radio signal which can be located within 1 km within the GSM radio network existing in Germany. The final destination can be determined by means of a handheld receiver (not shown) on the basis of the identity code G-ID sent by the relevant security unit 30.
  • a GPS module 94 can be provided in the security units 30, which emits a corresponding search signal.
  • An essential advantage of the method according to the invention and the device according to the invention consists in the modular construction of only 3 components, namely the security units 30, the monitoring units 40, 50 and the evaluation and operating unit 60. These basic modules are combined or combined as desired depending on the application and assigned and managed using management software.
  • a single monitoring unit 40 is sufficient, for example, to equip a smaller office or a shop.
  • the monitoring unit 40 is connected directly to the PC 61 of the evaluation and operating unit 60 via a connecting line 53.
  • the number of security units 30 depends on the number of objects 20 to be monitored.
  • the system can be expanded or supplemented at any time by adding further monitoring units 40 with assigned security units 30.
  • a plurality of monitoring units 40 can in turn be assigned to individual monitoring units 50 which forward the transmitted data as a repeater.
  • a central monitoring unit 50, at which all signals converge, is connected to the PC 61 via the connecting line 52.
  • the new components are assigned centrally via the evaluation and operating unit 60 or by means of the management software installed thereon and the assignment table 66.
  • the new items 20 are entered in the fields 68 provided for this purpose and are automatically assigned by the computer 61 or the software ,
  • the data are then sent to the security units 30 via the monitoring units 40, 50.
  • the installation effort is just as short as the preparation times, so that the system is ready for use in the shortest possible time (plug and secure).
  • the system is radio-based, i.e. no complex cables have to be laid.
  • Fuse units 30 and monitoring units 40, 50 preferably operate at different frequencies.
  • frequency hopping is carried out, i.e. the transceivers 36, 46 change the transmission frequency at regular time intervals. All signals are only transmitted for a few milliseconds, which further reduces power consumption.
  • the item management and security system 10 can be used in addition to the monitoring of items 20 at the same time for inventory or for inventory monitoring or management.
  • query codes are sent from the central evaluation and operating unit 60 via the monitoring units 40, 50. Addressing takes place via the identity codes G-ID and S-ID stored in the assignment table 66, so that all registered objects 20 are reached.
  • the query codes of the respective security unit 30 sends back a response signal via the transceiver 36, which is forwarded by the monitoring units 40, 50 to the evaluation and operating unit 60. This compares the received data with the stored data and carries out a comparison. The result is correspondingly processed and output on the monitor 62 or a printer (not shown).
  • the invention is not limited to one of the above-described embodiments, but can be modified in many ways.
  • the programming of the security units 30 can also take place via the GSM modules 92, 96.
  • Further areas of application are, for example, in the logistics area, namely when the securing units 30 are attached to a pallet or transport containers. These can not only be monitored inside a warehouse, but also outside during transport.
  • the evaluation and control unit 60 can be used at any time to determine whether all the pallets are still present and where they are currently located. The latter is preferably carried out via the GSM and / or GPS modules 92, 94, 96.
