Consequently, in some cases, the system may cause interference in other of the many equipment and instruments that work thanks to the same principle. Indeed, the restrictive legislation established in developed countries is well known, as well as the great saturation of artificial radiation in this region of the spectrum: television signals, radio, citizen bands, electromagnetic noise produced by engines and machines, etc. In addition, in the realization of this type of systems there is a significant difficulty in constructing an effective radio receiver, with a sufficiently small size to be able to be located inside the portable individual unit, without an external antenna and with low consumption.

  • the central sensors To avoid the mixing of signals that would occur in the central sensors if they received coded radiation emitted simultaneously by several individual controls, they have an electronic logic code selector, thanks to which, in the computer runs a program that makes the central transmitters enable each of the commands sequentially so that each of them only emits after receiving a particular coded signal.
  • the central sensors are sequentially capturing the encoded signals emitted by each of the individual controls, avoiding the said mixing or saturation effect, which would make it impossible to distinguish and decode the received signals.
  • the indicated communication procedure allows a luminous indication of whether the selected data has been registered in each command. It also allows, if desired, the specific response to be identified.

Abstract

Système d'enquête-réponse par infrarouge ayant pour but de permettre à plusieurs personnes de répondre à des questions, à l'aide de commandes individuelles sans fil, de sorte que les résultats soient enregistrés par un ordinateur, sous forme statistique ou individualisée, et que, si on le souhaite, ces résultats puissent être présentés immédiatement après la fin de la lecture des données sélectionnées par les individus participant à l'enquête. Le système consiste en un ensemble de commandes individuelles dotées de touches de sélection de l'option de réponse, ces commandes étant reliées à un ordinateur par l'intermédiaire d'un rayonnement infrarouge codé et d'une série d'émetteurs et de récepteurs de signaux, ces signaux étant envoyés à l'ordinateur lequel fait tourner un programme de gestion et de commande du processus de réception et d'enregistrement des données.
