Abstract

a. Procédé pour la transmission de données entre une centrale et plusieurs sous-stations. b. Procédé caractérisé en ce qu'à la fin de chaque appel une unité de calcul et de mesure du temps est mise en route, cette unité, sur la base de temps connu de réaction et de transit, fixe dans la sous-station et sur le trajet de transmission l'instant le plus rapproché possible où doit commencer la réponse qui doit arriver et libère pour cet instant l'enregistrement à la réception. c. L'invention s'applique notamment à la localisation de véhicules sur le terrain.at. Method for data transmission between a central and several substations. b. Method characterized in that at the end of each call a time calculation and measurement unit is started, this unit, on the basis of known reaction and transit time, fixed in the substation and on the transmission path the earliest possible moment at which the response to arrive must begin and for that moment releases the recording on reception. vs. The invention applies in particular to the location of vehicles in the field.
