Abstract

L'invention concerne un dispositif de mesure et de commande pour assurer la sécurité de ponts roulants. Chaque pont roulant comprend un émetteur et un récepteur et un moyen de détection de l'amplitude du signal électromagnétique reçu. Le moyen de détection comprend trois étages d'amplification 32, 40, 44 et un moyen de modification simultanée du gain de chacun des trois étages, ce moyen étant commandé par un comparateur 48 recevant une tension de référence VR1, VR2 et la sortie du moyen de détection. La mesure des modifications de gain (compteur 52) est proportionnelle à la distance entre les ponts roulants. On évite ainsi les collisions grâce à une meilleure évaluation de leur écartement à tout instant.
