Title (EN) VEHICLE GUIDANCE SYSTEM WITH RADIO BLOCKING
(FR) APPAREILLAGE DE GUIDAGE DE VEHICULES AVEC BLOCAGE RADIO
Abstract: front page image
(EN)A system for guiding unmanned vehicles (35) along a traffic layout includes a plurality of code devices (49, 51-55, 57-59) dividing the traffic layout into zones and identifying each zone by a unique code. Each vehicle includes control circuits (30) having code sensors (31) which sense the identifying code as the vehicle enters a zone and provide data to a present memory (80) which stores present address data representing the identity of the zone in which the vehicle is travelling. A past memory (81) stores past address data representing the identity of the zone in which the vehicle was previously travelling. A time slot generator (84) provides timing signals defining a plurality of time slots, each assigned to a different zone. A comparator circuit (83) responds to the past address data and the timing signals to effect transmission of a position signal during the time slot assigned to the zone in which the vehicle was previously travelling. A further comparator circuit (82) responds to the present address data and the timing signals to cause the vehicle to be halted whenever a position signal is received during the time slot assigned to the zone in which the vehicle is presently travelling.
(FR)Un appareillage pour guider des vehicules sans chauffeur (35) le long d"un trajet de circulation comprend une pluralite de moyens de codage (49, 51-55, 57-58) divisant la circulation en zones et l"identification de chaque zone par un code unique. Chaque vehicule comprend des circuits de controle (30) ayant des lecteurs de codes (31) qui detectent le code d"identification lorsque le vehicule entre dans une zone et fournissent des donnees a une memoire du present (80) qui emmagasine les donnees d"adresse du present representant l"identite de la zone dans laquelle le vehicule circule. Une memoire du passe (81) emmagasine des donnes passees representant l"identite de la zone dans laquelle le vehicule circulait precedemment. Un generateur de tranches de temps (84) fournit des signaux de chronometrage definissant une pluralite de tranches de temps, chacune attribuee a une zone differente. Un circuit de comparaison (83) repond aux donnes d"adresse du passe et aux signaux de chronometrage pour effectuer la transmission d"un signal de position pendant la tranche de temps attribuee a la zone dans laquelle le vehicule se deplacait precedemment. Un circuit de comparaison supplementaire (82) repond aux donnees d"adresse du present et aux signaux de chronometrage pour que le vehicule puisse etre arrete lorsqu"un signal de position est recu pendant la tranche de temps assignee a la zone dans laquelle le vehicule circule presentement.
