Abstract

The device includes a satellite navigation system (18). A person (22) carries a passive unit (20) which is activated by a coded radio signal from a transmitter (14). When the unit is activated a signal is transmitted received from the satellite navigation system which gives the terrestrial coordinates of the location of the person. The signal is decoded at a control centre (10). Preferably, the radio signal is in the long wave range. The coded radio signal is received via a network of very short wave transmitters, such as a radio telephone network.

Description

Die vorliegende Erfindung betrifft ein Ortungs- und Auffindungs­ system für unmündige Personen, insbesondere für Kinder.The present invention relates to a location and discovery system for minors, especially children.

Immer häufiger treten Verbrechen an Kindern auf. Die Eltern dieser Kinder können ihre Kinder nicht auf allen Wegen und insbesondere auf den Wegen zur Schule, zu Freunden oder zu Spielplätzen begleiten und bewachen.Crimes against children are becoming increasingly common. The parents of these children cannot their children in all ways and especially on the way to school, to friends or to Accompany and guard playgrounds.

Um sich dennoch jederzeit über den Aufenthaltsort ihrer Kinder Gewißheit zu verschaffen, dient das Ortungs- und Auffindungssystem gemäß der vorliegenden Erfindung.To find out about the whereabouts of their children at any time The location and location system serves to provide certainty according to the present invention.

Im wesentlichen besteht das System aus einem passiven Element, das die zu überwachende Person in geeigneter Weise am Körper trägt. Es kann sich hierbei um ein sehr kleines Bauelement handeln, das in oder unter der Kleidung versteckt getragen werden kann. Dieses Bauelement verhält sich normalerweise passiv. Es ist jedoch von terrestrischen Funkwellen ansprech- und aktivierbar. Die terrestrischen Funkwellen können hierbei von einem Langwellensender energiereich für ein sehr weites Suchgebiet abgestrahlt werden. Die hierbei aufgenommene Energie reicht aus, um ein Signal abzustrahlen, das von einem Satelli­ ten-Navigationssystem empfangen werden kann.The system essentially consists of a passive element, the person to be monitored on the body in a suitable manner wearing. It can be a very small component act that is worn hidden in or under clothing can be. This device normally behaves passive. However, it is responsive to and from terrestrial radio waves enableable. The terrestrial radio waves can do this from a long wave transmitter energetic for a very wide Search area are broadcast. The energy absorbed here is enough to emit a signal from a Satelli ten navigation system can be received.

Anstelle langwelliger Funkwellen kann auch ein Netz sehr kurz­ welliger Funkwellen benutzt werden, das mit vielen Relais­ stationen ähnlich einem Funktelefonnetz arbeitet. Die abgegebene und aufgenommene Energie ist hierbei schwächer, reicht aber für die vorliegenden Zwecke aus. Das verteilte System eines Netz­ werks hat den Vorteil, daß bestimmte Gebiete selektiert werden können und die Codierung des Signals auf einen bestimmten Empfänger einfacher ist. Instead of long-wave radio waves, a network can also be very short wavy radio waves are used with many relays stations works similar to a radio telephone network. The delivered and absorbed energy is weaker here, but is sufficient for the present purposes. The distributed system of a network factory has the advantage that certain areas are selected can and the coding of the signal to a specific Receiver is easier.  

In jedem Fall wird ein Reflexsignal in dem Bauelement erzeugt, das an das Satelliten-Navigationssystem so abgegeben wird, daß die terrestrischen Koordinaten der gesuchten Person sofort bestimmt und weitergeleitet werden können.In any case, a reflex signal is generated in the component, which is delivered to the satellite navigation system in such a way that the terrestrial coordinates of the person sought immediately can be determined and forwarded.

Weitere Einzelheiten, Merkmale und Vorteile der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung einer schematischen zeichnerischen Darstellung.Further details, features and advantages of the present Invention result from the following description of a schematic drawing.

Ein Teilnehmer 12 kann sich jederzeit mit einer Zentrale 10 in Verbindung setzen, die ständig in Kontakt mit einem terrestri­ schen Sender 14 steht. Wie zuvor erwähnt, kann der terrestrische Sender ein Langwellensender 14 mit relativ starker abgestrahlter Energie sein, die ausreicht, um ein am Körper einer gesuchten Person 22 getragenes Bauelement 20 so zu aktivieren, daß ein Reflexsignal ausgesandt wird, das sich von einem Satelliten- Navigationssystem 18 auffangen läßt.A participant 12 can contact a central office 10 at any time, which is constantly in contact with a terrestrial transmitter 14 . As previously mentioned, the terrestrial transmitter can be a long-wave transmitter 14 with relatively strong radiated energy, which is sufficient to activate a component 20 worn on the body of a wanted person 22 in such a way that a reflex signal is emitted, which is emitted by a satellite navigation system 18 can be caught.

Selbstverständlich besteht nach der bekannten Technik das Navigationssystem nicht nur aus einem Satelliten, sondern aus mehreren Satelliten, um eine exakte Ortung der Herkunft des Reflexsignals zu ermöglichen. Das vom Satelliten-Navigations- oder Ortungssystem ausgewertete Signal wird an eine Satelliten­ antenne 16 in der Zentrale zurückgestrahlt und mit den übrigen Daten verglichen. Stimmen die Codierungsdaten und die Ortungs­ daten überein, ist die gesuchte Person ziemlich genau dort zu orten, wo sie sich befindet. Die entsprechende Meldung kann von der Zentrale an den Teilnehmer 12 oder an andere geeignete Personen weitergeleitet werden.Of course, according to the known technology, the navigation system consists not only of one satellite, but of several satellites in order to enable the origin of the reflex signal to be precisely located. The signal evaluated by the satellite navigation or positioning system is returned to a satellite antenna 16 in the central office and compared with the other data. If the coding data and the location data match, the person sought can be located almost exactly where he is. The corresponding message can be forwarded from the central office to the subscriber 12 or to other suitable persons.

Zur Verdeutlichung des Systems dient auch die nachstehende Tabelle:
