Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Überwachung einer Gruppe mobiler Gegenstände, wobei mittels eines insbesondere tragbaren und der Gruppe zugeordneten Endgerätes elektromagnetische Signale empfangen werden, die von einem der Gruppe zugehörigen Gegenstand ausgesendet werden, wobei das Endgerät und die Gegenstände in unmittelbarem Funkkontakt stehen. Die Erfindung betrifft auch ein System zur Umsetzung des Verfahrens.The present invention relates to a method for monitoring a group mobile objects, whereby by means of a particularly portable and Group assigned terminal receive electromagnetic signals be sent out by an object belonging to the group be, the terminal and the objects in direct radio contact stand. The invention also relates to a system for implementing the method.
Anlagen, die derartige Verfahren zur Überwachung realisieren, sind beispielsweise in Kaufhäusern installiert. Dort sind die Waren jeweils mit einem abnehmbaren Transponder versehen, der ein Signal auslöst, sobald er in den Sende- und Empfangsbereich eines Endgerätes - hier in Form einer Antenne am Ausgang des Warenhauses - gerät. Diese Systeme sind bezüglich der Waren unspezifisch und funktionieren lediglich innerhalb der von den Antennen abgesteckten Gebiete. Ähnliche Systeme sind auch zur Überwachung von Personen, beispielsweise als "elektronische Handschellen", bekannt. Sie basieren auf dem Prinzip der Ortung eines Senders (z.B. GSM) mittels Peilung oder über ein GPS (Global Positioning System). Diese Systeme sind technisch aufwendig und für private Anwendungen kaum zu gebrauchen. Vor allem ist die Nutzung der jeweiligen Datennetze gebührenpflichtig, so dass sie für den täglichen Hausgebrauch zu kostenintensiv sind. Systems that implement such monitoring methods are installed in department stores, for example. There, the goods are each provided with a removable transponder, which triggers a signal as soon as it arrives in the transmission and reception area of a terminal - here in the form of an antenna at the exit of the department store. These systems are unspecific with regard to the goods and only work within the areas defined by the antennas. Similar systems are also known for monitoring people, for example as "electronic handcuffs". They are based on the principle of locating a transmitter (eg GSM) by means of bearing or via a GPS (Global Positioning S ystem). These systems are technically complex and can hardly be used for private applications. Above all, the use of the respective data networks is subject to a fee, so that they are too cost-intensive for everyday household use.
Aufgabe der Erfindung ist es nunmehr, ein Verfahren zur Überwachung von Gegenständen zu schaffen, das sich einfach und mit kostengünstigen Mitteln umsetzen lässt und das dem Nutzer eine einfache und komfortable Möglichkeit bietet, die ihn persönlich betreffenden Gebrauchsgegenstände jederzeit unter Kontrolle zu haben. Außerdem soll ein System zur Umsetzung des Verfahrens geschaffen werden.The object of the invention is now to provide a method for monitoring To create items that are easy and inexpensive can be implemented and this is a simple and convenient option for the user offers, at any time, the personal items of personal interest to him To be in control. In addition, a system is to implement the procedure be created.
Diese Aufgaben werden durch das Verfahren mit den kennzeichnenden Merkmalen des Anspruch 1 und das System nach Anspruch 8 gelöst.These tasks are characterized by the procedure with the Features of claim 1 and the system of claim 8 solved.
Der wesentliche Grundgedanke der Erfindung liegt darin, einen ständigen und unmittelbaren Funkkontakt zwischen dem vorteilhafterweise mobilen Endgerät und der Gruppe von zu behütenden Gegenständen aufrecht zu halten. Falls einer der Gegenstände aus dem Überwachungsbereich gerät, wird Alarm geschlagen, wobei der Überwachungsbereich im wesentlichen der unmittelbaren Umgebung des Nutzers entspricht und vorteilhafterweise von diesem eingestellt werden kann. Ein für die Erfindung besonders vorteilhafter Bereich liegt etwa zwischen einem und hundert Metern. Die einzelnen Geräte hängen damit gewissermaßen an einer "elektronischen Leine", die vom Endgerät gehalten wird, wobei das Endgerät in unmittelbarer Nähe des Nutzer sich befinden sollte. Solche Systeme lassen sich mit den heute gebräuchlichen Techniken, beispielsweise mit einer Nahfunktechnik wie insbesondere "Bluetooth", einfach und preiswert realisieren. Oft sind die entsprechenden Voraussetzungen in den schon heute erhältlichen Geräten vorhanden.The essential basic idea of the invention is a permanent and direct radio contact between the advantageously mobile terminal and the group of objects to be protected. If one of the Objects come out of the surveillance area, the alarm is raised, the surveillance area being essentially the immediate area corresponds to the user and can advantageously be adjusted by the user. A range which is particularly advantageous for the invention lies approximately between one and a hundred meters. The individual devices are, so to speak, attached to one "electronic leash" held by the terminal, the terminal in should be in the immediate vicinity of the user. Such systems can be with the techniques commonly used today, for example with a near radio technology such as "Bluetooth" in particular, easy and inexpensive to implement. Often they are corresponding requirements in the devices already available today available.
Ein weiterer Kerngedanke der Erfindung liegt darin, die einzelnen Gegenstände und/oder die dem Nutzer zuzuordnende Gruppe von Gegenständen zu individualisieren. Einem Endgerät ist somit eine bestimmte Zahl individueller Gegenstände zur Überwachung zugeordnet. Das erfindungsgemäße Verfahren wird dadurch realisiert, dass die von den Gegenständen ausgehenden Signale eine Kennung aufweisen, die individuell für einen einzelnen Gegenstand und/oder individuell für die Gruppe sind. Dabei sind die Kennungen der Gegenstände und/oder die Kennung der Gruppe in einem Speicher des Endgerätes in der Art einer Inventarliste hinterlegt. Anhand der Signale lassen sich dann die zur Gruppe gehörigen Gegenstände identifizieren. Ob der Gegenstand aus der Sphäre des Endgerätes gelangt, wird dadurch festgestellt, dass insbesondere die Stärke der jeweiligen Signale vom Endgerät ständig überprüft wird, wobei die Signalstärke als Maß für den Abstand zwischen Gegenstand und Endgerät (Empfangsradius) interpretiert wird. Dieser Radius ist vorteilhafterweise vom Nutzer einstellbar, um das System flexibel an die jeweilige Situation anpassen zu können. Sobald ein Gegenstand aus dem Empfangsradius gerät, wenn also die Signalstärke kleiner als ein vorgegebener Grenzwert ist, gibt das Endgerät dem Nutzer mit einem vernehmbaren Hinweis, beispielsweise einem optischen oder akustischen Signal, Alarm, wobei dem Nutzer angezeigt werden kann, welches Gerät verloren ist.Another key concept of the invention is the individual objects and / or the group of objects to be assigned to the user individualize. A certain number of individual devices is thus individual Objects assigned for surveillance. The method according to the invention is realized in that the signals emanating from the objects have an identifier that is individual for a single object and / or are individual for the group. Here are the identifiers of the objects and / or the identifier of the group in a memory of the terminal in Art an inventory list. The signals can then be grouped together identify related items. Whether the object from the sphere of the End device arrives, it is determined that in particular the strength of the respective signals from the terminal is constantly checked, the signal strength as Measure for the distance between object and end device (reception radius) is interpreted. This radius is advantageously adjustable by the user to be able to flexibly adapt the system to the respective situation. Once a Object comes out of the receiving radius, if the signal strength is lower than a predetermined limit, the terminal gives the user with a audible notification, for example an optical or acoustic signal, Alarm, whereby the user can be shown which device is lost.
Wegen der einfachen und kostengünstigen Mittel zur Umsetzung, eignet sich das Verfahren insbesondere zu Überwachung von persönlichen Gegenständen des täglichen Bedarfs. Dazu lassen sich neben der Geldbörse und dem Schlüssel weit mehr Dinge, ohne die sich heutzutage niemand mehr in der Öffentlichkeit bewegt, der Gruppe von Gegenständen zuordnen. In die Gruppe aufgenommen werden könnten beispielsweise ein Mobiltelephon, ein PDA (Personal Digital Assistent), ein USB-Stick (mobiles Speichermedium mit USB Schnittstelle) oder abnehmbare Bedienteile von KFZ-Audioanlagen. Da mit der Anzahl der mitgeführten Gegenstände das Risiko eines Diebstahls steigt und die Gefahr besteht, eines dieser Geräte einfach irgendwo zu vergessen, lassen sich die Geräte mit dem erfindungsgemäßen Verfahren sicher anleinen. Teure Verluste werden mit dem System vermieden.Because of the simple and inexpensive means of implementation, this is suitable Procedures in particular for monitoring personal belongings of the daily necessities. In addition to the wallet and the key, you can go far more things without which no one moves in public these days, assign to the group of items. Be included in the group for example, a cell phone, a PDA (Personal Digital Assistant), a USB stick (mobile storage medium with USB interface) or removable Controls of car audio systems. Because with the number of carried Objects the risk of theft increases and there is a risk of one To forget these devices somewhere, you can use the line the method of the invention safely. Expensive losses are incurred with the System avoided.
Für die Realisierung des Verfahrens sind zwei Methoden zu bevorzugen: Zum einen kann es vorteilhaft sein, das zu behütende Gerät mit einem eigenen Sender auszustatten, dessen durch eine Kennung individualisiertes Signal vom Endgerät aufgenommen wird. Diese Variante der aktiven Ausstrahlung ist insbesondere für Geräte vorteilhaft, die, wie Mobiltelephone oder PDA's, über eine Funkschnittstelle verfügen. In der anderen Variante werden passive Label, wie Transponder am Gegenstand angebracht, die ein vom Endgerät ausgesandtes Signal, individuell modifizieren und reflektieren. Das veränderte Signal wird dann vom Endgerät empfangen. Diese Variante ist vorteilhaft, da mit hoher Wahrscheinlichkeit in der Zukunft jeder Gegenstand, der einen Mindestwert übersteigt, bereits vom Hersteller mit einem ihn über derartige Identifikationsdaten zu identifizierenden Informationsträger versehen sein wird. Außerdem ist es dem Nutzer möglich, ein solches Label nachträglich an jedem beliebigen Gegenstand selbst anzubringen. Bei beiden Verfahren werden die einzelnen Gegenstände beim Endgerät durch Einloggen als zur Gruppe gehörig registriert. Das Einloggen kann flexibel gestaltet werden, so dass der Nutzer bei Bedarf denen einen oder den anderen Gegenstand in das System einbringen oder aus dem System herausnehmen kann.Two methods are preferred for the implementation of the method: one may find it advantageous to protect the device with its own transmitter to equip its signal from the terminal, individualized by an identifier is recorded. This variant of active broadcasting is especially for Devices advantageous, such as cell phones or PDAs, via a radio interface feature. In the other variant, passive labels, such as transponders on the Item attached, which is a signal sent by the terminal, individually modify and reflect. The changed signal is then from the terminal receive. This variant is advantageous because there is a high probability in the Future any item that exceeds a minimum value already from Manufacturer with an identification that can be identified using such identification data Information carrier will be provided. It is also possible for the user to to attach such a label to any object itself. In both methods, the individual items are carried through to the terminal Log in as a member of the group. Logging in can be flexible so that the user can use one or the other Insert or remove an object from the system can.
Die Identifikationsdaten bestehen wegen der Simplizität der Informationsträger vorteilhafterweise nur aus einer Ziffernfolge oder einem Code. Eine Übersetzung des Codes hin zu einer produktbezogenen Klartextinformation kann mit Hilfe einer zentralen Serveranwendung ermöglicht werden. Die Funktionalität des Online-Datenabgleichs mit dieser serverbasierten Datenbank über eine (Mobil-) Funkverbindung kann in das zu verwendende Endgerät integriert werden.The identification data exist because of the simplicity of the information carriers advantageously only from a sequence of digits or a code. A translation of the code to product-related plain text information can be created using a central server application. The functionality of online data comparison with this server-based database via a (mobile) Radio connection can be integrated into the end device to be used.
Diese Identifikationsdaten werden mittels eines drahtlosen Funkverfahren in ein mobiles, schnurloses Endgerät eingelesen. Wie schon dargelegt können als Endgerät Handys, PDAs oder ähnliche zur Kommunikation geeignete Geräte verwendet werden. Dazu wird das Endgerät mit einer entsprechenden Leseeinrichtung sowie zugehöriger Software ausgestattet. Mittels dieses Geräts wird anhand der Identifikationsdaten die Inventarliste der mitzuführenden Geräte angelegt und dauerhaft gespeichert. Im Normalbetrieb ist die Software darauf programmiert, den Empfangsradius des Geräts nach den in der Inventarliste eingegebenen Identifikationsdaten abzusuchen. Fehlt einer der Gegenstände, wurde er vergessen oder wurde er gestohlen, schlägt das Endgerät Alarm.This identification data is integrated into one using a wireless radio method Mobile, cordless device read. As already stated, as Mobile phones, PDAs or similar devices suitable for communication be used. For this, the end device is equipped with an appropriate Reading device and associated software. Using this device the inventory list of the devices to be carried is based on the identification data created and saved permanently. In normal operation the software is on it programmed the receiving radius of the device according to the in the inventory list search entered identification data. If one of the objects is missing, if it is forgotten or stolen, the end device sounds the alarm.
Um eine ständige Kontrolle über die Gegenstände zu haben, ist es vorteilhaft, vermittels des Endgerätes deren Vorhandensein innerhalb des eingestellten Empfangsradius in periodischen Abständen, beispielsweise im Sekundentakt, zu überprüfen. Zur Optimierung der Energieaufwendung können sich die Zyklen auch selbständig verändern. Wenn das System merkt, dass die Lage der Gegenstände unverändert bleibt, können die zeitlichen Abstände zwischen den Abfragen länger werden. Umgekehrt kann es vorteilhaft sein, einen Gegenstand, der sich gerade vom Endgerät entfernt, in kürzeren Abständen zu kontrollieren. Dabei ist es auch vorteilhaft, wenn der Alarm differenziert gegeben wird und die Art des Alarms dem Nutzer weitere Information gibt. So kann beispielsweise der Alarm durch ein unterbrochenes Piep-Geräusch realisiert werden, wobei die Frequenz des Tones für eines der Geräte und wobei die Länge der Unterbrechungen für die Entfernung des Gegenstandes vom Endgerät charakteristisch ist.In order to have constant control over the objects, it is advantageous by means of the terminal their presence within the set Receive radius at periodic intervals, for example every second check. The cycles can also be used to optimize energy consumption change independently. If the system notices that the location of the items remains unchanged, the time intervals between the queries can be longer become. Conversely, it may be beneficial to find an item that is straight away from the end device to check at shorter intervals. It is also there advantageous if the alarm is given differentiated and the type of alarm to the User gives further information. For example, the alarm can be triggered by a interrupted beep noise can be realized, the frequency of the sound for one of the devices and the length of the breaks for the distance of the object is characteristic of the terminal.
In einer besonders vorteilhaften Ausführungsform der Erfindung eignet sich das Verfahren auch zur Suche eventuell abhanden gekommener Gegenstände. Dazu kann ein außerhalb des Empfangsradius befindlicher Gegenstand beispielsweise mit einem Peilsender geortet werden, wobei der Peilsender insbesondere als Teil des Empfangsgerätes vorgesehen werden. Um eine Peilung vornehmen zu können, wird am Endgerät eine höhere Sende- und/oder Empfangsleistung abgerufen. Mit einer Richtantenne kann dann der Gegenstand eingepeilt werden. Mit der vom Endgerät ausgehenden Peilung wird es wegen der begrenzten Reichweite nur möglich sein, innerhalb eines relativ kleinen auf derzeit etwa 1 km begrenzten Radius zu orten. Um den Radius auszudehnen, ist es vorteilhaft, wenn die individuelle Kennung eines verlorenen Gegenstandes an ein anderes externes Endgerät übermittelt wird, mit dem dann eine Kontaktaufnahme zu dem Gegenstand versucht wird. So kann das Endgerät beispielsweise über GSM eine Verbindung zu dem anderen Endgerät aufbauen. Schlägt das primär zuständige Endgerät Alarm, können die Identifikationsdaten an andere (vorher definierte) Geräte übermittelt werden, die dann ihrerseits ihren Empfangsradius nach dem vermissten Gegenstand absuchen. "Findet" eines dieser benachrichtigten Geräte den verlorenen Gegenstand, kann es via Telekommunikationsverbindung (voice, email, SMS) den Nutzer über den Fund informieren. Alternativ kann eine Sprachverbindung aufgebaut werden. Bei gelungener Kontaktaufnahme durch das externe Endgerät wird so dem zugeordneten Endgerät eine Nachricht über den Verbleib des verlorenen Gegenstandes übermittelt.This is suitable in a particularly advantageous embodiment of the invention Procedure for searching for any lost items. To can be an object outside the reception radius, for example be located with a DF transmitter, the DF transmitter in particular as part of the receiving device can be provided. To make a bearing too higher transmission and / or reception performance accessed. The object can then be aimed using a directional antenna. With the bearing coming from the terminal, it becomes because of the limited Range can only be possible within a relatively small to currently around 1 km locate limited radius. To extend the radius, it is advantageous if the individual identification of a lost item to another external one Terminal is transmitted, with which then contacting the Object is tried. The terminal can, for example, use GSM Establish a connection to the other end device. Strikes the primary responsible Terminal alarm, the identification data can be passed on to other (previously defined) Devices are transmitted, which in turn then their reception radius after the search for the missing item. "Finds" one of these notified devices the lost item, it can be sent via telecommunication connection (voice, email, SMS) inform the user about the find. Alternatively, one Voice connection can be established. If the contact is successful external terminal is thus a message about the assigned terminal Whereabouts of the lost item transmitted.
