Title (EN) ANTI-COLLISION DETECTION AND WARNING SYSTEM
(FR) SYSTEME DE DETECTION ET D'AVERTISSEMENT ANTI-COLLISION
Abstract:
(EN) An anti-collision detection and warning system comprising a plurality of detectors (2) mounted on a vehicle (5) which receive light pulses emitted by a transmitter (1) located on a vehicle (4) whose location is to be communicated to an operator of the vehicle (5) by means of a receiver (3) mounted, for example, in the operator's cabin. The detectors (2) include a shield (18) having a window (17) shaped so that the detector (2) receives light only from within a predefined zone. In a particular form the zone is divided into an inner zone and an outer zone, the inner zone being closed to the vehicle (5). This arrangement allows an operator of the vehicle (5) to detect the presence of the vehicle (4) before a collision occurs.
(FR) Un système de détection et d'avertissement anti-collision comprend plusieurs capteurs (2) montés sur un véhicule (5) qui reçoivent les impulsions lumineuses émises par un émetteur (1) placé sur un autre véhicule (4) dont l'emplacement doit être communiqué au conducteur du véhicule (5) au moyen d'un récepteur (3) monté par exemple dans la cabine du conducteur. Les capteurs (2) comportent un bouclier (18) présentant une fenêtre (17) dont la forme est conçue de sorte que le capteur ne reçoive que la lumière émise depuis l'intérieur d'une zone prédéfinie. Dans une forme particulière, la zone est divisée en une zone interne et en une zone externe, la zone interne étant plus proche du véhicule (5). Cet agencement permet au conducteur du véhicule (5) de détecter la présence de l'autre véhicule (4) en prévision d'une collision éventuelle.
