Title
(EN) SYSTEM FOR GENERATING A RECORDING ELECTROMAGNETIC FIELD HAVING A GIVEN CONFIGURATION
(FR) SYSTEME DE GENERATION D'UN CHAMP ELECTROMAGNETIQUE D'ENREGISTREMENT AYANT UNE CONFIGURATION DONNEE
Abstract
(EN)
The present invention pertains to the field of alarm-signal generating systems and essentially relates to a system for generating a recording electromagnetic field. This system includes an emitting unit (1) with an emitter (3) and an emitting antenna grid (4) as well as a receiving unit (2) with a receiver (7) and a receiving antenna grid (8), wherein said units are located at a distance from each other. The emitting and receiving units include diagram-generation means (6, 9) and phase-generation means (5, 10), respectively. When the electromagnetic field has a complex configuration or when it is necessary to monitor simultaneously a plurality of closed premises, the method involves using electromagnetic-radiation transformers (14) that modify the direction and the shape of said electromagnetic radiation according to the shape and the dimensions of the areas to be monitored.
(FR)
Cette invention se rapporte aux systèmes émettant des signaux d'alarme, et concerne un système de génération d'un champ électromagnétique d'enregistrement. Ce système comprend une unité émettrice (1) avec un émetteur (3) et une grille d'antenne émettrice (4), ainsi qu'une unité réceptrice (2) avec un récepteur (7) et une grille d'antenne réceptrice (8), les deux unités étant distantes l'une de l'autre. Les unités émettrice et réceptrice comprennent respectivement des systèmes de génération de diagramme (6, 9) et des systèmes de génération de phase (5, 10). Lorsque le champ électromagnétique possède une configuration complexe ou lorsqu'il est nécessaire de contrôler simultanément plusieurs locaux fermés, on utilise des transformateurs de rayonnement électromagnétique (14) qui modifient la direction et la forme dudit rayonnement électromagnétique en fonction de la forme et des dimensions des zones à contrôler.
