FR2871917A1 - Emergency bidirectional calling system for displaying position of e.g. tag carrier, has transmitter/receiver where exchange of data, with information on location of carrier of transmitter/receiver, is allowed if parties are authenticated - Google Patents

Abstract

The system has a central unit connected to a telephone jack, and inserted between a wall grip and the jack. The central unit is directly set from a telephone. Exchange of data between calling and called parties is allowed only if the parties are authenticated. The data has information on location of carrier of a portable transmitter/receiver. The data is transmitted under recorded voice messages. An independent claim is also included for a network of calling systems.

Description

AUTONOMOUS AND SECURE SYSTEM OF REMOTE LOCATION

  The present invention relates to a remote location system, which can securely transmit the position of a person equipped with a location system and additional data: - following an authenticated remote call to the remote caller or - following a local alert to a list of remote recipients.

  This remote location system consists of at least one radiofrequency transceiver connected to a communication network, in particular for example a telephone network, hereinafter referred to as a central station, of portable transmitter / receiver identification and transmission objects. call, subsequently called medallions and transmitters / receivers fixed thereafter called re-emitter terminals widening the area of location.

  Existing call systems, especially for isolated people, have a call tag connected to a specific telephone.

  They only allow the simple transmission of a call to one or more preprogrammed telephone numbers on activation of a button of the medallion. These systems are unidirectional and the range of action is restricted. In case of call of the holder of the medallion, generated voluntarily or following the activation of a sensor, the precise position is not determined nor communicated to the external operator receiving the call.

  The present invention aims to extend the scope of current systems and to add a precise location of people. The said location is bidirectional: the emergency call initiated by the person also transmits its position at the time of the call on the one hand and the central can on external call authenticated locate the person and automatically return the position thereof accompanied by a suitable message on the other hand.

  A particular location system described in patent application No. 0405166 proposes displaying the position of a badge wearer on a location map. Its use is limited to the place where it is implanted.

  The system that is the subject of the invention makes it possible to extend these uses to remote locations by making it possible to locate thanks to bidirectional communication between medallions, central offices and remote calling stations.

  Thus the system can communicate to authenticated remote persons an indication of the actual location where the locket is located during the call. This indication can be in the form of prerecorded voice messages of the type in the garden ', in the garage', in the room ', ...

  All requests for location can also be memorized with their date of arrival at the plant so that they can be checked later.

  The call from the medallion can originate from: - a voluntary call from its bearer, - detection by a sensor integrated in the medallion or not, a situation requiring a call.

  The control panel can be configured remotely by an authorized person having secret codes that authenticate it in order to collect data from the medallion or additional sensors for a defined period of time. This data can subsequently be collected via the communication network, in particular for example a telephone network, by authorized and authenticated callers.

  A first example of implementation can be: A person A wants to join the telephone a person B equipped with the location system and emergency call, if the person B does not pick up the line after a number of ringtones pre-established , the person A can activate, by a pre-established sequence of keys, which can contain a secret code, the localization which can then answer by a message adapted to the situation: person A absent, in the case where the locket is not located, person A present indicating his position.

  The remote activation of the location of a person by presenting a secret code that is specific to the medallion called, so if there are several people wearing medallions, a caller may be allowed to locate one person and not the other .

  Person A, who may be away from a telephone to answer, is also notified of the call by a light and sound indication on the medallion, pressing the emergency call button of the medallion then generates a response. by a specific message such as: Well received call, I call you back as soon as possible. The system, which is the subject of the invention, thus offers new and reassuring services for the relatives of isolated, elderly or dependent or semi-disabled persons, etc. ... They can if they are present or absent from their place of residence, if they are in distress or not.

  Another example of implementation can be: Person B equipped with a localization system and emergency call, is in danger, malaise, or other, it presses the emergency call button of his medallion.

  The control panel sequentially dials the pre-recorded call numbers and transmits: - a pre-recorded message giving the following situation - a pre-recorded message of the medallion identifier and / or the name of the person B followed - a pre-recorded message giving the position at the time of the call. The calls are automatically repeated until an acknowledgment sequence composed by one of the called numbers is received.

  The embodiments described hereinafter are not exhaustive and are given by way of example only.

  One of the embodiments may be: The central consists of an electronic directly connected to a telephone jack, it is intercalated as a thief plug between the wall outlet and the telephone jack. It accepts any telephone.

  The control panel is set directly from the phone, including the recording of messages.

  The medallion consists of a radio frequency transponder, it is provided with a battery ensuring a lifetime of several years.

  In a larger residence with, for example, outbuildings, gardens and parks, re-transmitting terminals must be arranged in such a way as to ensure the radio coverage of the desired area.

  The location of the medallions is then done by triangulation and calculation of the barycentre levels of the received signals.

  Each medallion has a unique identifier that is recognized by the central. The information storage memory of the control panel is adapted to the number of medallions managed, the number and the size of the recorded messages.

  The dates and times of external calls that activated a location are recorded in the control panel. This information can be consulted and in the case of misuse, the secret code of access to the location function can be changed.

  Another embodiment may be: The information relating to the wearer of the medallion and the call numbers to be dialed and the message to be sent are stored in the memory of the medallion.

  In the event of an emergency call, the medallion transmits all this information to the central unit that executes the request.

  In the case of an outside call requesting a location, the identifiers of all medallions present and authorized are transmitted.

  A medallion can be configured to remain secret and not respond to a location request In this embodiment the central units are universal and accept any medallion allowed that enters their field of action.

  This mode is particularly suitable if the persons concerned move between different places equipped with the system object of the invention. This mode makes it possible to widen considerably the zone of security offered, it is enough to equip the concerned places, clubs of the old age, etc ....

  The two embodiments described above are not exclusive, but can be combined, a central that can be parameterized with data relating to permanent medallions, but also accept information from medallions invited or temporarily present.
