Abstract
Description
Die Erfindung betrifft ein Verfahren zum Kontrollieren des Betretens oder Verlassens eines Bereichs durch Personen oder bewegliche Sachen, wobei die Personen oder Sachen jeweils einen Signalgeber tragen, der einen auf die jeweilige Person oder Sache bezogenen Code sendet oder auslöst, und wobei der Empfang eines bestimmten Codes als Warnsignal für ein unberechtigtes Betreten oder Verlassen des Bereichs durch die jeweilige Person oder Sache detektiert wird, und wobei mindestens ein zweiter, von dem ersten Signalgeber unabhängiger Signalgeber vorhanden ist, welcher ein Signal abgibt oder auslöst, das, wenn es gleichzeitig mit dem bestimmten, ein Warnsignal darstellenden Code empfangen wird, die Berechtigung der jeweiligen Person oder Sache, welcher der betreffende, das Warnsignal darstellende Code zugeordnet ist, zum Verlassen des Bereichs anzeigt. Ebenso betrifft die Erfindung eine Vorrichtung zum Kontrollieren des Zugangs oder Verlassens eines Bereichs durch Personen oder bewegliche Sachen mit einer Detektionseinrichtung, welche Codes, die den Personen oder Sachen zugeordnete Signalgeber abgeben oder auslösen, erkennt und die beim Empfang eines nicht zum Betreten oder Verlassen des Bereichs berechtigenden Codes ein Warnsignal abgibt, wobei die Detektionseinrichtung den gleichzeitigen Empfang zweier Codes als Signal für das gleichzeitige berechtigte Betreten oder Verlassen des Bereichs durch mindestens zwei Personen oder Sachen erkennt.The invention relates to a method for checking entering or leaving an area People or moving things, the people or Stuff each carry a signaling device, the one on sends the person or thing related code or triggers, and being the reception of a particular Codes as a warning signal for unauthorized entry or The person or leaves the area Thing is detected, and at least a second, signal generator independent of the first signal generator is present which emits or triggers a signal, that if it coincides with the particular one Warning signal representing code is received Authorization of the respective person or thing, which the relevant code representing the warning signal assigned to leave the area. The invention also relates to a device for Control the entry or exit of an area by people or moving things with a Detection device, which codes the people or give things assigned to signalers or trigger, recognizes and that when receiving a not to Entering or leaving the area authorizing code emits a warning signal, the detection device the simultaneous receipt of two codes as a signal for the simultaneous authorized entry or exit of the Area by at least two people or things recognizes.
In der US 5 079 541 werden ein Verfahren und eine Vorrichtung zur Absicherung und Kontrolle des Zugangs und Verlassens einer Säuglingsstation in einem Krankenhaus beschrieben. Zu diesem Zweck werden gemäß der US5 079 541 den Säuglingen Windeln angelegt, welche jeweils mit einem Signalgeber bestückt sind. Bei diesem Signalgeber kann es sich beispielsweise um einen Transponder handeln, der im Wirkungsbereich eines elektromagnetischen Feldes einen bestimmten Code aussendet.In US 5 079 541 a method and a Device for securing and controlling access and Leaving an infant ward in a hospital described. For this purpose, according to US5 079 541 the babies put on diapers, each with a Signalers are equipped. With this signal generator it can are, for example, a transponder that is in the Effective range of an electromagnetic field sends out certain code.
Wird ein Säugling, welcher eine derartige Windel trägt, in den Wirkungsbereich einer Detektionseinrichtung gebracht, so erfaßt die Detektionseinrichtung das vom Signalgeber ausgegebene Signal und gibt ihrerseits ein Warnsignal aus. Auf diese Weise ist sichergestellt, daß der Versuch, einen Säugling unbefugt aus der Station zu tragen, erkannt wird und ein Alarm ausgelöst wird. Nachteilig ist jedoch, daß die Detektionseinrichtung auch dann einen Alarm ausgibt, wenn berechtigte Personen, beispielsweise das Pflegepersonal oder die Eltern, mit dem Säugling den überwachten Bereich verlassen oder betreten wollen. Dies macht es erforderlich, den Signalgeber von dem Säugling zu entfernen, bevor die Station verlassen oder betreten wird, oder zusätzliche Maßnahmen, wie das Einholen einer besonderen Erlaubnis des Aufsichtspersonal zum Betreten oder Verlassen der Station, zu ergreifen.If an infant wearing such a diaper in the effective range of a detection device brought, the detection device detects that from Signal generator output signal and in turn inputs Warning signal off. This ensures that trying to get an infant out of the ward without permission wear, is recognized and an alarm is triggered. However, it is disadvantageous that the detection device too then issues an alarm when authorized persons, for example the nursing staff or the parents leave the monitored area to the infant or want to enter. This requires that Remove the siren from the infant before the Will leave or enter station, or additional Measures such as obtaining a special permit of supervisory staff to enter or leave the Station to take.
Letzteres ist einerseits umständlich und kann andererseits beispielsweise dann nicht eingehalten werden, wenn in einer Notfallsituation ein Säugling schnell in eine andere Station des Krankenhauses gebracht werden muß. Die Möglichkeit, den Signalgeber von dem Säugling durch einfaches Abnehmen der Windel zu entfernen, bringt des weiteren die Gefahr von Manipulationen mit sich, mit denen es leicht möglich wird, einen Säugling trotz der eingerichteten Kontrollen zu entführen.On the one hand, the latter is cumbersome and can on the other hand, for example, then not complied with if an infant is in an emergency situation quickly taken to another hospital ward must become. The possibility of the signal generator from the Infant by simply removing the diaper remove, furthermore brings the risk of Manipulations with themselves with which it is easily possible an infant despite the controls in place to kidnap.
Eine Vorrichtung zur Sicherung von Gegenständen der eingangs angegebenen Art ist aus der DE 36 04 307 A1 bekannt. Bei der bekannten Vorrichtung werden jeweils gleichartige, aktive Daten aussendende Signalgeber und Empfänger eingesetzt. Deren Signale sind so aufeinander abgestimmt, daß eine Datenspeicherung, Datenverarbeitung sowie Datenweiterleitung möglich ist. Gemäß einer in der DE 36 04 307 A1 beschriebenen Ausführung ist dabei der Signalgeber, der der zur Entnahme eines Gegenstandes berechtigten Person zugeordnet ist, in analoger Weise ausgebildet wie das Empfangs- und Auswertgerät, das dem zu schützenden Gegenstand zugeordnet ist. Indem sowohl der von der zur Entnahme berechtigten Person getragene Signalgeber als auch der dem zu schützenden Gegenstand zugeordnete Signalgeber gleichartige Signale abgeben, kann so auf Basis von von den Empfangs- und Antwortgeräten und vom Signalgeber kontinuierlich abgegebenen Daten kontinuierlich überprüft werden, ob der jeweils geschützte Gegenstand entnommen werden darf oder nicht.A device for securing objects of the type specified at the outset is from DE 36 04 307 A1 known. In the known device identical signal transmitters which transmit active data and Receiver used. Their signals are so on top of each other voted that data storage, data processing and data forwarding is possible. According to one in the The version described in DE 36 04 307 A1 is Signal generator that is used to remove an object is assigned to an authorized person in an analogous manner trained as the receiving and evaluation device that the is assigned to the object to be protected. By both the person carried by the person authorized to withdraw Signal generator as well as the object to be protected assigned signal generators emit similar signals, can be based on the reception and Response devices and from the signal generator continuously data are continuously checked whether the each protected object may be removed or Not.
Überwachungsvorrichtungen der voranstehend erläuterten Art erweisen sich in der Praxis als störungsanfällig, da die jeweils ausgetauschten Signale vielfach keine eindeutige Identifizierung zulassen. Monitoring devices of the above Art prove to be prone to failure in practice because the signals exchanged in many cases none Allow clear identification.
Eine Möglichkeit, diesen Nachteil zu überwinden, ist in der GB 23 32 547 A aufgezeigt. Gemäß diesem Dokument wird ein ebenfalls gleichartige Signale nutzendes Überwachungssystem so ausgelegt, daß die in einer Transponder-Hierarchie am höchsten angesiedelten Signalgeber zuerst identifiziert werden. Dazu können die höheren Transponder so gestaltet sein, daß sie auf ein Abfragesignal schneller antworten, als Signalgeber niederer Klassen. Dieser Stand der Technik zeigt somit, wie die sich beim gleichzeitigen Empfang gleicher Signale einstellenden Störungen vermieden werden können. Allerdings zeichnet sich die dazu erforderliche Auswertung durch eine hohe Komplexität aus, die einen großen technischen Aufwand bei der praktischen Verwirklichung der aus der GB 23 32 547 A bekannten Vorrichtung mit sich bringt.One way to overcome this disadvantage is in the GB 23 32 547 A shown. According to this document a likewise using similar signals Surveillance system designed so that the in a Transponder hierarchy most highly located Signalers are identified first. You can do that higher transponders be designed so that they are on a Answer interrogation signal faster than signal generator lower classes. This prior art thus shows like the same when receiving the same signals malfunctions can be avoided. However, the necessary for this emerges Evaluation by a high level of complexity, the one great technical effort in the practical Realization of the known from GB 23 32 547 A. Device.
Die Aufgabe der Erfindung besteht darin, mit einfachen Mitteln ein Verfahren und eine Vorrichtung der eingangs genannten Art zu schaffen, welche einerseits sicher verhindern, daß Personen oder Gegenstände unerkannt und unberechtigt einen überwachten Bereich betreten oder verlassen, und welche andererseits das unkomplizierte Betreten und Verlassen des Bereichs für solche Personen und Sachen ermöglichen, die dazu berechtigt sind.The object of the invention is simple Averaging a method and a device to create the type mentioned, which on the one hand is safe prevent people or objects from being recognized and entering a monitored area without authorization or leave, and which on the other hand the uncomplicated Such people enter and leave the area and enable things that are authorized to do so.
Hinsichtlich des Verfahrens wird diese Aufgabe ausgehend von dem eingangs erläuterten Stand der Technik dadurch gelöst, daß sich die Art und Weise, mit welcher der eine Signalgeber das von ihm abgegebene Signal überträgt oder auslöst, sich von der Art und Weise unterscheidet, mit dem der andere Signalgeber das von ihm abgegebene Signal überträgt oder auslöst. With regard to the method, this task is based on from the prior art explained above resolved that the way in which one Signal transmitter transmits the signal it emits or triggers, differs from the way with which the other signal generator the signal emitted by him transmits or triggers.
Gemäß der Erfindung wird der gleichzeitige Empfang zweier unabhängig voneinander abgegebener Signale als Berechtigung für das Betreten oder Verlassen eines geschützten Bereichs interpretiert, wobei eines der Signale für sich anzeigt, das der Träger des dieses Signal abgebenden Signalgbers an sich den betreffenden Bereich nicht verlassen darf. Auf diese Weise kann die zum Verlassen oder Betreten des geschützten Bereichs alleine nicht berechtigte Person in Begleitung eines dazu Berechtigten ohne zusätzliche Kontrollen den betreffenden Bereich betreten oder verlassen. So können beispielsweise auch in Notfällen problemlos Säuglinge einer Säuglingsstation von dem dazu berechtigten Pflegepersonal oder ihren Eltern aus dem Säuglingszimmer gebracht und in andere Stationen eines Krankenhauses getragen werden, ohne daß wertvolle Zeit für umständliche Identifizierungs- und Kontrollvorgänge verloren geht. Gleichzeitig ist durch die erfindungsgemäße, eindeutige Zuordnung des Warnsignals zu dem jeweiligen Säugling sichergestellt, daß kein Unberechtigter Säuglinge aus dem Säuglingszimmer entfernen kann. Dabei besteht ein besonderer Vorteil der Erfindung darin, daß die Kontrolle des Zugangs und des Verlassens des überwachten Bereichs berührungslos durchgeführt werden kann.According to the invention, the simultaneous reception of two signals delivered independently of one another as Authorization to enter or leave one protected area, one of the Signals indicating that the wearer of this Signal-emitting signal transducer per se May not leave area. In this way, the to leave or enter the protected area alone not authorized person accompanied by one Authorized persons without additional controls Enter or leave the area. For example Even in emergencies, infants easily Infant ward by the authorized nursing staff or brought her parents out of the nursery and into other wards of a hospital are carried, without valuable time for cumbersome Identification and control processes are lost. At the same time is clear through the inventive Allocation of the warning signal to the respective infant ensured that no unauthorized infants from the Can remove baby room. There is a particular advantage of the invention in that the control access to and exit from the monitored area can be carried out without contact.
Gemäß der Erfindung werden zwei unterschiedliche Signalübertragungssysteme eingesetzt, um die Signale des einen und des anderen Signalgebers zu erzeugen. Auf diese Weise kann für die sicherheitsrelevante Identifizierung der Person oder Sache, die einen bestimmten Bereich alleine nicht verlassen oder betreten darf, eine spezialisierte, hinsichtlich ihrer technischen Verwirklichung im Umfeld des geschützten Bereichs einzigartige Signalübertragung verwirklicht werden, während für die berechtigten Personen im Umfeld des geschützten Bereichs vielfach eingesetzte, gleichartige Signalübertragungssysteme eingesetzt werden.According to the invention, two are different Signal transmission systems used to transmit the signals of the to generate one and the other signal generator. To this Way can for security-related identification of the person or thing covering a particular area not allowed to leave or enter alone, one specialized, in terms of their technical Realization in the environment of the protected area unique signal transmission can be realized while for the authorized persons in the environment of the protected area often used, similar Signal transmission systems are used.
Vorzugsweise gibt bei einem derart erfindungsgemäß ausgebildeten System ein Signalgeber als passives Element sein Signal aufgrund einer Fremderregung ab, während der andere Signalgeber aktiv ein Signal aussendet. Als passiv arbeitender Signalgeber kann beispielsweise ein Transponder eingesetzt werden. Alternativ läßt sich eine passive Erzeugung eines Signals beispielsweise jedoch auch dadurch bewerkstelligen, daß der eine Signalgeber bei Annäherung an einen Ausgang des Bereichs ein elektro-magnetisches Feld stört und damit ein Warnsignal auslöst, während der andere Signalgeber ein Sender ist, der ein bestimmtes, codiertes Signal abgibt.Preferably there is one according to the invention trained system a signal generator as a passive element his signal drops due to external excitation during the other signal transmitters actively send out a signal. As passive working signal generator can, for example Transponders are used. Alternatively, one can passive generation of a signal, for example also accomplish that one signal generator when approaching an output of the range an electro-magnetic Disturbs the field and thus triggers a warning signal, while the other signal transmitter is a transmitter, the one delivers a specific, coded signal.

Selbstverständlich können auch andere Transponder, welche den Anforderungen der Erfindung gerecht werden, eingesetzt werden.Transponders that are intended for use with - the invention are currently suitable, for example under the trade name "LEGIC" or "MAYFAIR" available. Of course, others can too Transponder meeting the requirements of the invention do justice, be used.
Grundsätzlich ist es möglich, die von den zum Zutritt oder Verlassen berechtigten Personen oder Sachen getragenen Signalgeber so auszugestalten, daß auch berechtigte Personen oder Sachen jeweils nur gemeinsam mit einer zweiten, einen Signalgeber tragenden Person oder Sache den überwachten Bereich verlassen oder betreten kann. Gemäß einer besonders bevorzugten Ausgestaltung der Erfindung tragen bestimmte Personen oder Sachen jedoch einen Signalgeber, welcher einen ersten Code abgibt, der anzeigt, daß die betreffende Person oder Sache nicht zum Verlassen oder Betreten des Bereichs berechtigt ist, während bestimmte andere Personen oder Sachen jeweils einen Signalgeber tragen, der einen anderen, sich von dem ersten Code unterscheidenden Code abgibt, welcher zum Betreten oder Verlassen des Bereichs berechtigt. Bei dieser Ausgestaltung der Erfindung können sich die zum Betreten oder Verlassen berechtigten Personen oder Sachen auch ohne Begleitung in dem überwachten Bereich bewegen. Gleichzeitig können unberechtigte Personen oder Sachen in Begleitung von berechtigten die Kontrollen passieren. Besonders vorteilhaft ist diese Ausgestaltung dann, wenn der überwachte Bereich eine Säuglingsstation in einem Krankenhaus ist und die Säuglinge einen Signalgeber tragen, dessen Code nicht zum Betreten oder Verlassen der Säuglingsstation berechtigt, während andere Personen, wie Eltern oder Pflegepersonal, jeweils einen Signalgeber tragen, dessen Codierung zum Betreten oder Verlassen der Säuglingsstation berechtigt. Dabei kann die Praxistauglichkeit der Erfindung dadurch weiter verbessert werden, daß die zum Betreten oder Verlassen des Bereichs berechtigten Personen oder Sachen unterschiedliche Grade der Berechtigung besitzen. Auf diese Weise kann der von den Signalgebern jeweils abgegebene Code zur Zugangskontrolle anderer Bereiche genutzt werden, die jeweils nur von einem bestimmten Kreis der berechtigten Personen oder Sachen betreten werden dürfen.Basically it is possible to get access from the or leaving authorized persons or things worn signaling device so that also authorized persons or things only together with a second person wearing a signal transmitter or thing leave the monitored area or can enter. According to a particularly preferred Embodiment of the invention carry certain people or things but a signal generator, which one first code that indicates that the Person or thing not to leave or enter the Area is entitled while certain others People or things each carry a signal generator, the other, different from the first code makes a distinctive code, which to enter or Authorized to leave the area.

Claims (10)
- A method for detecting whether persons or mobile objects have entered or exited an area (S), wherein the persons or objects respectively carry a signal transmitter that transmits or triggers a code (A1-A6, B2, B3, C) referring to the respective person or object, wherein the reception of a certain code (A1-A6) is detected as a warning signal that is indicative of the respective person or object entering or exiting the area in an unauthorized fashion, wherein at least a second signal transmitter is provided independent of the first signal transmitter, and wherein the second signal transmitter transmits or triggers a signal that, if it is received simultaneously with the certain code that represents a warning signal, is indicative of the exit authorization of the respective person or object, to which the code representing the warning signal is assigned,
characterized in that
the fashion, in which the one signal transmitter transmits or triggers the signal delivered by it differs from the fashion, in which the other signal transmitter transmits or triggers the signal delivered by it. - The method according to Claim 1,
characterized in that
one signal transmitter acts as a passive element and transmits its signal in response to a separate excitation, and in that the other signal transmitter actively sends out a signal. - The method according to one of Claims 1 or 2,
characterized in that
one signal transmitter disturbs an electromagnetic field when it approaches an exit from the area and thusly triggers a warning signal, and in that the other signal transmitter consists of a transmitter that transmits a certain coded signal. - The method according to one of the preceding claims,
characterized in that
certain persons or objects carry a signal transmitter that transmits a first code (A1-A6), wherein the first code indicates that the respective person or object is not authorized to exit or enter the area, and in that certain other persons or objects respectively carry a signal transmitter that transmits another code (B2, B3, C) that differs from the first code (A1-A6), wherein the second code authorizes the person or object to enter or exit the area. - The method according to one of the preceding claims,
characterized in that
the area consists of a nursing station (S) in a hospital, and in that the infants carry a signal transmitter that transmits or triggers a code (A1-A6) which does not authorize an entry or exit of the nursing station (S), wherein other persons, for example, parents and hospital personnel, respectively carry a signal transmitter that transmits or triggers a code (B2, B3, C) which authorizes'to enter or exit the nursing station (S). - The method according to one of the preceding claims,
characterized in that
the persons or objects authorized to enter or exit the area are assigned different degrees of authorization. - A device for detecting whether persons or mobile objects have entered or exited an area (S), with a detection device (6, 7) which recognizes codes (A1-A6, B2, B3, C) that are transmitted or triggered by signal transmitters assigned to the persons or objects and which transmits a warning signal when it receives a code (A1-A6) that does not authorize entry or exit to the area, wherein the detection device (6, 7) recognizes the simultaneous reception of two codes (A1-A6, B2, B3, C) as a signal for the simultaneous authorized entry or exit of the area (S) by at least two persons or objects,
characterized in that
the fashion, in which the one signal transmitter transmits or triggers the signal delivered by it differs from the fashion, in which the other signal transmitter transmits or triggers the signal delivered by it. - The device according to Claim 7,
characterized in that
at least a second detection device (6, 7) is provided which monitors a second section of the monitored area which lies adjacent to the first section monitored by the first detection device (6, 7), and in that an evaluation device (8) is provided which transmits a warning signal if one of the detection devices (6, 7) also transmits a warning signal. - The device according to Claim 7 or 8,
characterized in that
the signal transmitter is cast-in in a skin-compatible mass and fixed on the body of the respective person. - A utilization of the device according to one of Claims 7-9 for detecting the entry or the exiting of a nursing station (S) in a hospital.
