Abstract

An alarm signal is transmitted by the radio device (4) carried by an isolated worker (2) and is received by portable equipment (1) situated at a point accessible to a public telephone network (6). In response to an alarm signal from the portable radio, the processing equipment (1) transmits a pre-recorded voice message to a surveillance station (15, 16). The portable equipment is intended to enable communication between an isolated worker (2) provided with a portable radio device (4), and personnel in a surveillance service. An alarm signal is transmitted by the portable radio device (4) and is received by portable equipment (1) which is situated by the user in a region accessible to the radio signal, and also accessible to a public network, such as a GSM mobile telephone network (6). In response to an alarm signal from the portable radio, the processing equipment (1) transmits a pre-recorded voice message to at least one surveillance station (15, 16), via a public communication network. The portable equipment includes an input aerial (9) and interface (8), a processing unit (7), and an output interface (10) and output aerial (11).

State of the art The document FR-A-2357966 describes an alarm installation intended to ensure the safety of an isolated person in a building or an industrial premises. The person concerned is provided with a radio transmitter which is triggered automatically when it is placed in a horizontal position. In the event of an incident, an alarm signal is transmitted by radio to a portable radio receiver, which is first made available to a stationary employee when the user enters

L'alarme est transmise, de preference par radio, a un recepteur personnel. Celui-ci provoque alors automatiquement la composition d'un numero de telephone d'une centrale qui lui est connectee par une ligne teiephonique de maniere a etablir une communication audio et/ou video entre ia centrale et l'utilisateur. Ce systeme, utilisant une ligne telephonique fixe, est plus particulierement destine a assurer la surveillance de personnel figees ou malades a leur domicile.

The alarm is transmitted, preferably by radio, to a personal receiver. This then automatically causes the composition of a telephone number of a central which is connected to it by a telephone line so as to establish an audio and / or video communication between the central and the user. This system, using a fixed telephone line, is more particularly intended to ensure the monitoring of frozen or sick personnel at their home. The document WO-A-01/78034 describes an alarm transmission apparatus comprising a telephone, for example a mobile telephone of the GSM type, connected to a communication device which, when it receives an alarm from a circuit o alarm to which it is connected, causes the automatic dialing of a preset telephone number and the transmission of a preprogrammed message in the communication device. The transmitted message can be a voice message. The assembly constituted by the alarm circuit, the communication device and the mobile telephone must be placed in an area accessible by the public telephone network and is therefore not suitable for

Comme represente a la figure l, un equipement portable 1 est destine a communiquer d'une part avec un travailleur isole 2 et, d'autre part, avec du personnel ou des services de surveillance 3. II est destine a permettre d'assurer la protection d'un travailleur isole 2 meme lorsque celui-ci se trouve dans une zone non accessible par un reseau de communication public, sans necessiter d'infrastructure de relais particuliere dans cette zone. La zone non couverte par le reseau public peut notamment etre situee a l'interieur ou dans les sous-sols  As shown in FIG. 1, portable equipment 1 is intended to communicate on the one hand with an isolated worker 2 and, on the other hand, with personnel or surveillance services 3. It is intended to make it possible to ensure the protection of an isolated worker 2 even when he is in an area not accessible by a public communication network, without the need for a specific relay infrastructure in this area. The area not covered by the public network can in particular be located inside or in the basements

o d'un batiment.o a building.

L'utilisateur de l'equipement portable 1, c'est-a-dire le travailleur isole 2, est classiquement muni d'un appareil radio portatif 4 qui emet un signal d'alarme en cas d'incident, par exemple en cas de malaise, d'accident, d'agression ou de s tout autre probleme. L'appareil radio portatif, de portee limitee peut, par exemple, etre constitue par un talkie-waikie specialise comportant des moyens de detection d'un incident. A titre d'exemple, un tel appareil radio portatif peut comporter un capteur de position detectant une perte de verticalite ou une absence de mouvement et provoquant, eventuellement apres une zo temporisation, I'emission par l'appareil radio portatif 4 d'un signal d'alarme constituent un appel de detresse. La transmission du signal d'alarme s'effectue done sur un reseau de communication prive 5, qui peut etre de tout type connu, par exemple de type PMR (<< private mobile radio >), 3RP (reseau radio a ressources partagees) ou conforme a la norme Tetra. Les frequences utilisees  The user of the portable equipment 1, that is to say the isolated worker 2, is conventionally provided with a portable radio device 4 which emits an alarm signal in the event of an incident, for example in the event of discomfort, accident, assault or any other problem. The portable radio device, of limited range can, for example, be constituted by a specialized talkie-waikie comprising means for detecting an incident. For example, such a portable radio device may include a position sensor detecting a loss of verticality or an absence of movement and causing, possibly after a zero delay, the emission by the portable radio device 4 of a signal. constitute a distress call. The alarm signal is therefore transmitted over a private communication network 5, which can be of any known type, for example of the PMR (<< private mobile radio>), 3RP (shared resources radio network) type or complies with the Tetra standard. The frequencies used

Lorsque l'utilisateur 2 doit intervenir sur un site, notamment dans une zone 14 s non accessible par le reseau de communication radio public 6, il depose au prealable l'equipement portable 1 dans une zone accessible a la fois par le reseau de communication radio public 6 et par l'appareil radio portatif a partir de la zone 14. A titre d'exemple, il peut disposer l'equipement 1 dans un local en surface ou, eventuellement, dans sa voiture, a proximite du site. II enregistre, zo dans ['ensemble de traitement 7, un message vocal destine a fournir au personnel de surveillance 3 les informations necessaires a sa localisation. En effet, en cas d'incident, lorsqu'un signal d'alarme est transmis a l'equipement portable 1 par l'appareil radio portatif 4, le message vocal preenregistre est automatiquement diffuse sur le reseau de communication radio public 6 par z I'equipement portable 1 en direction d'un terminal portatif 15 et/ou d'un terminal fixe 16 permettant de contacter le personnel de surveillance 3, charge de  When the user 2 must intervene on a site, in particular in a zone 14 s not accessible by the public radio communication network 6, he deposits beforehand the portable equipment 1 in an zone accessible both by the radio communication network public 6 and by the portable radio device from zone 14. For example, he may have the equipment 1 in a room on the surface or, possibly, in his car, near the site. It records, zo in the processing unit 7, a voice message intended to provide the surveillance personnel 3 with the information necessary for its location. Indeed, in the event of an incident, when an alarm signal is transmitted to the portable equipment 1 by the portable radio device 4, the pre-recorded voice message is automatically broadcast on the public radio communication network 6 by z I portable equipment 1 towards a portable terminal 15 and / or a fixed terminal 16 making it possible to contact the surveillance personnel 3, responsible for

L'equipement portable 1 permet egalement a l'utilisateur 2 d'entrer en communication phonique avec le personnel de surveillance, a partir de son appareil radio portatif 4, sans sortir de la zone 14 non accessible par le reseau  The user therefore records a new message every time he changes the site and describes his place of intervention there. he may complete it with any indication he considers desirable, for example the time of his arrival on the site and the duration planned for the intervention. Cot recording can be carried out from the portable radio 4. The portable equipment 1 also allows the user 2 to enter into phonic communication with the surveillance personnel, from his portable radio 4, without leaving of zone 14 not accessible by the network
