  • the telephone may be a device connected to the conventional line telephone network or, for example, an NMT telephone operating on radio waves.
  • switches, relays and other actuators are connected to the receiving telephone device, by means of which actuators the desired control measures are acccomplished.
  • the receiver must be a telephone, which is a telephone device connected to a line telephone network, or correspondingly an NMT telephone.
  • These devices are complex and because they are continuously connected to the telephone network, they also place a considerable load on the network.
  • the data is transmitted wirelessly by means of a paging transmission network to the receiver part of the pager, from which the data is conveyed to the actuator.

  • the time used for data transmission is thus very short and the essential factor is that only one receiver identifies the short message transmitted to it. It is inherent to the system that several different messages can obviously be sent simultaneously to different receivers.
  • the object of the invention also comprises a device for transmitting data wirelessly, the said device including a transmitter system, by means of which the data is transmitted to the receiver system, which is connected to communicate the data or control command to the actuator.

  • the message is transmitted by means of an intercom dialling device in which both the number of the receiving device and the message to be transmitted are preprogrammed.
  • the intercom dialling device may, for example, be the same type of audiofrequency device as is used in connection with an impulse dialling telephone.
  • the transmission includes the number of the receiving device and, in addition to the message to be transmitted, a security code to prevent the receiving of an incorrect message.

Abstract

Un procédé permet de transmettre sans fil des données entre un système d'émetteur (10) et un récepteur (20) reliés de façon à communiquer ces données ou un signal de commande à un actuateur (23). Selon l'invention, les données sont transmises sans fil, grâce à un réseau de transmission d'appels personnels (10), au module de réception (21) d'un dispositif d'appel personnel (20) à partir duquel elles sont relayées vers l'actuateur (23). Un circuit de commande logique (24) et une horloge (25) sont connectés à ce module de réception afin de pouvoir commander l'actuateur.
