Description
Die Erfindung bezieht sich auf ein System zur automatischen Personenüberwachung im häuslichen Umfeld, unter Verwendung von Sensoren zur Erfassung von charakteristischen Parametern, die einer Überwachungszentrale zugeleitet werden, die im Bedarfsfall eine Alarmzentrale, insbesondere einen Dienstleister alarmiert.The invention relates to a system for automatic personal monitoring in the home environment, using sensors for detecting characteristic parameters, which are fed to a monitoring center, which alerts an alarm center, in particular a service provider if necessary.
Derartige Systeme für spezielle Überwachungssituationen sind bereits mehrfach vorgeschlagen worden. So beschreibt beispielsweise die WO 94/20939 ein System bei dem ein Bewegungsdetektor mit einem zeitgesteuerten Alarmschalter gekoppelt ist, der typische Ruhezeiten ausblendet, um bei Ausbleiben eines Bewegungssignals innerhalb eines vorgeplanten Zeitraums, der auf eine mögliche Bewegungsstellung oder Bewusstlosigkeit der überwachten Person hindeuten kann, einen Alarm auszulösen.Such systems for special monitoring situations have already been proposed several times. Thus, for example, WO 94/20939 describes a system in which a motion detector is coupled to a timed alarm switch which masks typical rest periods in order to detect a missed motion signal within a pre-planned time period which may indicate a possible movement or unconsciousness of the monitored person To trigger an alarm.
Aus der Offenlegungsschrift DE 196 27 996 A1 ist eine akustische Raumüberwachung bekannt geworden, bei der ein Lautstärkepegel der länger als ein einstellbarer Zeitraum überschritten worden ist das Alarmsignal auslöst. Ein solches Gerät eignet sich aber praktisch nur zur Überwachung von Kleinkindern (Babyphon).From the published patent application DE 196 27 996 A1 , an acoustic room monitoring has become known in which a volume level has been exceeded for longer than an adjustable period of time, the alarm signal triggers. However, such a device is practically only for monitoring infants (babyphone).
Die WO 99/06979 beschreibt ein Gerät bei dem Mikrofone oder Orts- oder Bewegungsmelder vorgesehen sind. Entweder kann über das Mikrofon durch Eingabe spezieller Codewörter ein Alarm ausgelöst werden, was aber für viele Überwachungsfälle völlig ungeeignet ist, oder aber ein Ort- und Bewegungsmelder mit einem nachgeschalteten Auswerteprogramm stellt fest, ob eine erfasste Person sich über einen bestimmten Zeitraum nicht mehr bewegt hat. WO 99/06979 describes a device in which microphones or location or motion detectors are provided. Either an alarm can be triggered via the microphone by entering special codewords, but this is completely unsuitable for many monitoring cases, or a location and motion detector with a downstream evaluation program determines whether a detected person has not moved for a certain period of time ,
Schließlich zeigt die GB 2 306 275 A ein akustisches oder Temperatursignale auswertendes Babyphon, das aber wegen seiner speziellen Ausrichtung auf die Überwachung von Kleinkindern für die Überwachung von Personen in ihrem häuslichen Umfeld, dahingehend ob sie sich "normal" verhalten nicht geeignet ist.Finally, GB 2 306 275 A shows an acoustic or temperature signals sounding baby monitor, but because of its special focus on the monitoring of infants for the monitoring of people in their home environment, whether they behave "normal" is not suitable.
Aus der EP 1 071 055 ist ein System zur automatischen Personenüberwachung im häuslichen Umfeld unter Verwendung von Sensoren zur Erfassung von charakteristischen Parametern, die einer Überwachungszentrale zugeleitet werden, bekannt. Die Überwachungszentrale alarmiert im Bedarfsfall eine Alarmzentrale, insbesondere einen Dienstleister. Die Sensoren erfassen eine Mehrzahl regelmäßig benutzter oder betätigter häuslicher Geräte (auch Messgeräte). Die Sensordaten werden personalisiert und automatisch der Überwachungszentrale zugeleitet, welche die einlaufenden Daten unter Verwendung eines Expertensystems mit vorgegebenen Regeln auswertet.From EP 1 071 055 a system for automatic personal surveillance in the home environment using sensors for detecting characteristic parameters, which are fed to a monitoring center, known. If necessary, the monitoring center alerts an alarm center, in particular a service provider. The sensors detect a plurality of regularly used or operated domestic devices (also measuring devices). The sensor data is personalized and automatically forwarded to the monitoring center, which evaluates the incoming data using an expert system with predetermined rules.
Der Erfindung liegt daher die Aufgabe zugrunde ein System zur automatischen Personenüberwachung im häuslichen Umfeld der eingangs genannten Art so auszugestalten, dass es in der Lage ist, ohne großen Aufwand und ohne teure Installationen das alltagstaugliche Verhalten dieser Personen zu erkennen, ohne dass diese dabei in irgendeiner Weise mitwirken müssen und ohne dass es nur um die Erkennung von Extremsituationen wie Bewusstlosigkeit oder dergleichen geht,und dass gleichzeitig die Vertraulichkeit der Personendaten gewährleistet werden kann.The invention is therefore the object of a system for automatic personal monitoring in the home environment of the type mentioned in such a way that it is able to easily and without expensive installations to recognize the everyday use behavior of these people, without this in any case Must cooperate and without it is only about the detection of extreme situations such as unconsciousness or the like, and at the same time the confidentiality of the personal data can be guaranteed.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass die Sensoren eine Mehrzahl regelmäßig benutzter oder betätigter häuslicher Geräte erfassen und dass die Sensordaten personalisiert und automatisch einem ersten Dienstleister zugeleitet werden, der die einlaufenden Daten mit verschlüsselten Personendaten an den eigentlichen Bearbeitungsdienstleister weiterleitet, welcher sie unter Verwendung eines Expertensystems mit vorgegebenen Regeln auswertet.To solve this problem, the invention provides that the sensors detect a plurality of regularly used or actuated domestic devices and that the sensor data are personalized and automatically forwarded to a first service provider, the incoming data with encrypted personal data to the actual Forwarding processing service provider, which evaluates them using an expert system with predetermined rules.
Im Gegensatz zu den sehr begrenzten akustischen Meldegeräten oder aufwendigen Orts- und Bewegungsmeldern, die im Übrigen immer nur ganz spezielle Einzelpunkte erfassen können und nicht eine echte Analyse des Personenverhaltens, werden mit den erfindungsgemäßen Sensoren in erster Linie übliche Haushaltsgeräte erfasst, die beispielsweise das Öffnen und Schließen der Kühlschranktür oder das Ein- und Ausschalten des Herdes, des Geschirrspülers, der Kaffeemaschine, des Fernsehers oder der Toilettenspülung. Darüber hinaus kann über die erfindungsgemäß zu verwendenden Gerätesensoren das Einschalten von Lichtschaltern, noch dazu mit einer raumbezogenen Auflösung, das Öffnen und Schließen von Türen, Rolläden oder die Benutzung des Telefons überwacht werden. Werden diese Geräte innerhalb eines bestimmten Zeitraums nicht oder extrem häufig betätigt so liefern diese Abweichungen, insbesondere bei Auswertung über ein Expertensystem und vor allem bei Auswertung einer Mehrzahl solcher Gerätedaten - das bloße Nichtbetätigen eines einzelnen Lichtschalters oder eines Rolladens ist natürlich für sich allein noch wenig aussagekräftig - ein gutes Bild dafür, ob sich die überwachte Person "normal" verhält. Unter Geräten, die mit Hilfe der erfindungsgemäßen Einfachsensoren überwacht werden, können dabei auch Messgeräte zählen beispielsweise der Wasserverbrauch, Stromverbrauch oder Gasverbrauch, wobei diese Werte gegebenenfalls vom System auch direkt als Dienstleistung der entsprechenden städtischen Versorgungsbetriebe abgerufen werden können. Schließlich soll unter häuslichen Geräten die häufiger benutzt oder betätigt werden auch beispielsweise das Bett, die Couch oder sein Sessel verstanden werden, wobei entsprechende Matratzensensoren erfassen wann die überwachte Person sich hinsetzt oder hinlegt wann er wieder aufsteht und wie er sich bewegt.In contrast to the very limited acoustic signaling devices or complex location and motion detectors, which can only ever detect very specific items and not a real analysis of the behavior of people are detected with the sensors according to the invention in the first place usual household appliances, for example, the opening and Closing the refrigerator door or turning on / off the cooker, dishwasher, coffee machine, TV or toilet flush. In addition, the switching on of light switches, even with a spatial resolution, the opening and closing of doors, shutters or the use of the phone can be monitored via the present invention to be used device sensors. If these devices are not operated or extremely frequently actuated within a certain period of time, these deviations provide, in particular when evaluated by an expert system and, above all, when evaluating a plurality of such device data - the mere non-actuation of a single light switch or a shutter is, of course, by itself not very meaningful - a good picture of whether the supervised person behaves "normally". Devices that are monitored with the aid of the simple sensors according to the invention can also include measuring devices, for example water consumption, power consumption or gas consumption, these values also being able to be called up by the system directly as a service of the corresponding municipal utilities. Finally, among home appliances that are used or operated more frequently, for example, the bed, the couch or his chair to be understood, with appropriate mattress sensors detect when the monitored person sits down or lying down when he gets up and how he moves.
Insbesondere aus der Kombination der dabei gewonnenen Daten lässt sich über ein Expertensystem vollautomatisch und ohne weiteres Zutun, insbesondere ohne Zutun der überwachten Person selbst, sehr gut feststellen, ob die Person ein in allen Punkten normales Leben führt, oder ob charakteristische Abweichungen in einer bestimmten Richtung vorliegen, die möglicherweise ein Eingreifen erfordern. Wenn beispielsweise alle überwachten Parameter der Norm entsprechen aber die Kühlschranktür nicht mehr geöffnet wird und auch der Herd nicht mehr eingeschaltet wird so gibt dies zwar keine Veranlassung den Notarzt sofort vorbeizuschicken, da man ja feststellt, dass sich die Person nach wie vor normal in der Wohnung bewegt. Es scheint aber, dass sie aus welchen Gründen auch immer Ausfallerscheinungen hat oder ein Erkrankung, so dass sie nicht mehr isst oder trinkt und dies ist natürlich Grund dafür entweder einen Kontrollanruf zu machen und mit der Person zu sprechen oder aber einen Pflegedienstleister zur Kontrolle vorbeizuschicken.In particular, from the combination of the data obtained in this way, it is very easy to determine via an expert system automatically and without further intervention, in particular without the supervised person himself, whether the person leads a normal life in all points, or if characteristic deviations in a certain direction that may require intervention. For example, if all the monitored parameters meet the standard but the refrigerator door is not opened and the stove is no longer turned on so there is no reason to send the ambulance immediately, because one notices that the person is still normal in the apartment emotional. However, it seems that for whatever reason, she has a history of failure or illness so she no longer eats or drinks, and this, of course, is the reason for either making a control call and talking to the person or sending a care provider to inspect.
Dabei ist es möglich aber auch recht aufwendig, das System so auszugestalten, dass jede Sensormeldung automatisch an die Zentrale weitergeleitet wird. Einfacher ist es wenn die Sensoren und/oder die häusliche Weiterleitungsstation bei der die Signale aller Sensoren der Wohnung zusammenlaufen, die Sensordaten insbesondere die Häufigkeit der Betätigung eines Gerätes, mit vorgegebenen Daten vergleicht und nur bei Abweichungen an die Zentrale weiterleitet.It is possible, but also quite expensive, to design the system in such a way that each sensor message is automatically forwarded to the control center. It is easier if the sensors and / or the domestic forwarding station in which the signals of all the sensors of the apartment converge, the sensor data, in particular the frequency of operation of a device, compared with predetermined data and forwarded only in case of deviations to the center.
Bei der Datenanalyse der Sensordaten kann im einfachsten Fall ein fester Wert vom Anwender vorgegeben sein. Zum Beispiel kann ein weniger als einmaliges Kühlschranköffnen pro Tag automatisch zur Auslösung eines Alarms führen.In the simplest case, the data analysis of the sensor data may specify a fixed value by the user. For example, opening less than one refrigerator per day may automatically trigger an alarm.
Besonders vorteilhaft ist es aber wenn als Expertensystem ein lernendes System eingesetzt wird, welches das Verhalten der überwachten Person lernt und nur bei Abweichungen Alarme auslöst. Solche Verfahren existieren beispielsweise zur Erkennung von Mobiltelefon- oder Kreditkartenmissbrauch.However, it is particularly advantageous if a learning system is used as the expert system, which learns the behavior of the monitored person and only triggers alarms in the event of deviations. Such methods exist, for example, for the detection of mobile phone or credit card misuse.
Das System kann darüber hinaus Alarme unterschiedlichster Dringlichkeit erzeugen z. B. in Abhängigkeit davon wie wahrscheinlich ein kritischer Zustand vorliegt. Bei Ausbleiben von Signalen von allen überwachten Geräten über einen bestimmten Zeitraum - einschließlich beispielsweise des Ausbleibens von Geräten des Matratzensensors in der Nacht - dürfte mit hoher Wahrscheinlichkeit ein kritischer Fall vorliegen, während das bloße Nichteinschalten des Herds bei ansonsten normalen Sensormitteilungen sicher eine allenfalls unkritische Störung im Verhalten und Befinden der überwachten Person andeutet. Diese Alarme unterschiedlicher Dringlichkeit können an beliebige Stelle weitergeleitet werden über Fax, E-Mail, SMS oder dergleichen und können von einem Kontrollanruf über die Benachrichtigung eines häuslichen Pflegedienstes bis zur sofortigen Alarmierung einer Notarztzentrale reichen.The system can also generate alarms of various urgency, eg. Depending on how likely a critical condition is. In the absence of signals from all monitored devices over a certain period of time - including, for example, the absence of devices of the mattress sensor at night - is likely to be a critical case, while the mere non-switching of the stove with otherwise normal sensor messages certainly a possibly uncritical disorder in the Behavior and health of the monitored person implies. These alarms of varying urgency can be forwarded to any location via fax, e-mail, SMS, or the like, and can range from a control call to the notification of a home care service to the immediate alerting of an emergency medical center.
Um die Vertraulichkeit zu gewährleisten, kann in Ausgestaltung der Erfindung vorgesehen sein, dass die Zentrale aufgespalten auf zwei Dienstleister verteilt ist, von denen der eine die einlaufenden Daten mit verschlüsselten Personendaten an den eigentlichen Bearbeitungsdienstleister weiterleitet und auch die Verbindung zur Alarmzentrale übernimmt.In order to ensure the confidentiality, can be provided in an embodiment of the invention that the central split is distributed to two service providers, one of which the incoming data with encrypted personal data to the actual processing service provider forwards and also takes over the connection to the alarm center.
Dies lässt sich dabei besonders einfach realisieren wenn von vorneherein zwei getrennte Datenbanken vorgesehen sind, nämlich eine Benutzerdatenbank mit personenbezogenen Daten der überwachten Person, Kontaktadressen, Pflegediensten, Pseudonymen oder dergleichen, die dann beim einen Dienstleister angesiedelt ist und einer Sensordatenbank zur Auswertung der eingehenden Sensordaten. Der die Benutzerdatenbank verwaltende erste Dienstleister erzeugt das Pseudonym und gibt seine Erreichbarkeit und das Pseudonym an den zweiten Dienstleister weiter der dann die eigentliche Überwachung durchführt aber die Identität des Betroffenen nicht kennt. Im Alarmfall schickt der zweite Dienstleister eine Nachricht mit dem Pseudonym an den ersten Dienstleister. Dieser ermittelt die zugehörige Person und startet eine adäquate Reaktion wie beispielsweise die Benachrichtigung von Verwandten, Pflegediensten oder dergleichen, ohne selbst Zugriff auf die Daten des Betroffenen zu haben.This can be particularly easily implemented if two separate databases are provided from the outset, namely a user database with personal data of the monitored person, contact addresses, care services, pseudonyms or the like, which is then located at a service provider and a sensor database for evaluating the incoming sensor data. The first service provider managing the user database generates the pseudonym and forwards its reachability and the pseudonym to the second service provider who then performs the actual monitoring but does not know the identity of the person concerned. in the In case of alarm, the second service provider sends a message with the pseudonym to the first service provider. This determines the associated person and starts an adequate response such as the notification of relatives, care services or the like, without even having access to the data of the person concerned.
Der Vorteil des erfindungsgemäßen Systems besteht zum einen darin, dass überhaupt keine aktive Mitarbeit des Betroffenen erforderlich ist. Darüber hinaus hat das System den Vorteil, dass die absolute Vertraulichkeit gewahrt werden kann. Durch die Überwachung der Mehrzahl von häuslichen Geräten sinkt die Rate an Fehlalarmen, weil etwa ein Betroffener vergessen hat anzurufen, und schließlich bietet das erfindungsgemäße System eine sehr kostengünstige Nutzung vorhandener Infrastrukturen.The advantage of the system according to the invention is firstly that no active cooperation of the person concerned is required at all. In addition, the system has the advantage that the absolute confidentiality can be maintained. By monitoring the majority of domestic appliances, the rate of false alarms decreases because, for example, a person concerned has forgotten to call, and finally the system according to the invention offers a very cost-effective use of existing infrastructures.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels sowie anhand der Zeichnung, die schematisch ein Ablaufdiagramm eines erfindungsgemäßen Systems zeigt.Further advantages, features and details of the invention will become apparent from the following description of an embodiment and with reference to the drawing, which shows schematically a flow diagram of a system according to the invention.
Mit 1 bis 4 sind unterschiedliche Betätigungssensoren bezeichnet, die beispielsweise das Betätigen oder die Benutzung eines bestimmten Gerätes im Haushalt der überwachten Person anzeigen wie beispielsweise ein Matratzensensor, ein Sensor der das Öffnen der Kühlschranktür oder das Einschalten des Herdes, der Toilettenspülung oder des Fernsehers überwacht. Diese Sensorsignale werden bevorzugt nicht direkt an eine Zentrale weitergeleitet sondern an eine häusliche Weiterleitungsstation 5, die gegebenenfalls mit einer Auswerteeinheit 6 gekoppelt sein kann, so dass sie nicht nur eine Sammelweiterleitung veranlasst, sondern bereits eine Vorsichtung und Vorbeurteilung der Sensordaten, ehe sie an die Zentrale weitergeleitet werden. Die Zentrale ist dabei im dargestellten Ausführungsbeispiel auf zwei unterschiedliche Dienstleister verteilt und umfasst eine beim ersten Dienstleister angesiedelte Benutzerdatenbank 7 mit personenbezogenen Daten der überwachten Person, Kontaktadressen, Pflegediensten, Pseudonymen oder dergleichen. Von ihr werden die mit einem entsprechenden Pseudonym versehenen Daten an die Sensordatenbank 8 beim zweiten Dienstleister weitergeleitet, wobei diese Sensordatenbank mit einem Expertensystem 9 gekoppelt ist um die eingehenden Sensordaten auszuwerten. Das Auswerteergebnis wird von der Sensordatenbank 8 an die Benutzerdatenbank 7 zurückgemeldet, die dann ihrerseits - da ja nur sie weiß, welcher Patient sich hinter dem anonymisiert ausgewerteten Daten verbirgt - unterschiedliche Alarme auslösen kann, beispielsweise kann sie eine Anfrage bei der überwachten Person starten (Rückrufstation 10) oder aber bei Verwandten anrufen (Weiterleitungsstation 11), sie kann auch bei einem Pflegedienst 12 eine Alarmmeldung absetzen oder gegebenenfalls direkt die Notarztzentrale 13 verständigen. Selbstverständlich sind dabei auch eine ganze Reihe weiterer unterschiedlicher Alarmstufen möglich, wie auch statt der gezeigten vier Gerätesensoren eine Vielzahl weiterer Sensoren in das System einbezogen werden können. Darunter können sich auch Sensoren über die Verbrauchsdaten im jeweiligen Haushalt wie Wasserverbrauch, Stromverbrauch oder Gasverbrauch befinden.With 1 to 4 different operating sensors are referred to, for example, indicate the operation or use of a particular device in the household of the monitored person such as a mattress sensor, a sensor that monitors the opening of the refrigerator door or turning on the stove, the toilet flush or the TV. These sensor signals are preferably not forwarded directly to a central office but to a domestic forwarding station 5, which may optionally be coupled to an evaluation unit 6, so that it causes not only a group forwarding, but already a Vorsichtung and pre-assessment of the sensor data before they go to the control center to get redirected. In the illustrated exemplary embodiment, the center is distributed over two different service providers and comprises a
Hinsichtlich der Ausgestaltung der Sensoren und ihre Weiterverschaltung bestehen grundsätzlich eine Reihe unterschiedlicher Möglichkeiten. Geht man einmal von einem typischen Fall, nämlich einem Sensor der das Einschalten des Herdes meldet aus, so ist die einfachste Möglichkeit die, dass der Sensor jedes Mal an die Zentrale meldet wenn er eingeschaltet wird. Die Zentrale entscheidet dann was zu veranlassen ist.With regard to the design of the sensors and their interconnection, there are basically a number of different possibilities. Assuming a typical case, namely a sensor that indicates that the cooker is switched on, the easiest way is that the sensor reports to the control panel each time it is switched on. The center then decides what to do.
Statt dieser Direktmeldung kann der Herdsensor jedes Mal an die lokale Weiterleitungsstation eine Meldung abgeben wenn er eingeschaltet wird. Diese lokale Weiterleitungsstation übernimmt die Signalübermittlung für alle Sensoren im Haushalt. Nur die Weiterleitungsstation muss Fernkommunikation beherrschen, alle anderen Geräte können über eine lokale Funkstrecke (z. B. DECT) an der Weiterleitungsstation hängen. In diesem Fall kann - wie weiter oben ja bereits beschrieben wurde - entweder grundsätzlich von der lokalen Weiterleitungsstation eine Weiterleitung der Sensordaten erfolgen oder aber es kann erst eine Prüfung und Auswertung der Daten in der Weiterleitungsstation stattfinden, so dass nur dann, wenn die lokale Weiterleitungsstation mit ihren beschränkten Prüfungsmöglichkeiten einen Notfall zu erkennen glaubt, ein Weiterschalten erfolgen.Instead of this direct message, the hearth sensor can send a message to the local forwarding station each time it is turned on. This local forwarding station handles the signal transmission for all sensors in the household. Only the forwarding station must be able to handle remote communication, all other devices can hang over a local radio link (eg DECT) at the forwarding station. In this Case can - as already described above - either basically from the local forwarding station a forwarding of the sensor data done or it can take place only a check and evaluation of the data in the forwarding station, so that only if the local forwarding station with their limited Examining options to detect an emergency believes an advancement is done.
Schließlich wäre es auch möglich, dass der Sensor, beispielsweise durch die Herdelektronik selbst, weiß wie oft er eingeschaltet werden muss oder soll. Er meldet sich dann bei der Zentrale wenn er nicht oft genug eingeschaltet wurde. Dies senkt zwar die Kommunikationskosten, ist aber auf der anderen Seite aufwendig wegen der entsprechend teueren Sensorelektronik. Finally, it would also be possible that the sensor, for example by the stove electronics itself, knows how often it must or should be turned on. He then contacts the head office if he was not turned on often enough. Although this lowers the communication costs, it is expensive on the other hand because of the correspondingly expensive sensor electronics.
