Thus, even the sensor unit 1 could be put into stand-by mode when the traffic situation, eg. B. by temporary road closures, can expect that no traffic violations can be committed.

Abstract

L'invention concerne un système de surveillance de la circulation consommant peu de courant. L'invention vise à abaisser encore la consommation d'énergie de systèmes de surveillance de la circulation mobiles et/ou fixes par rapport à l'état de la technique. A cet effet, le système de surveillance de la circulation selon l'invention, qui comprend les principales unités fonctionnelles suivantes : un capteur servant à enregistrer un véhicule routier qui roule à une vitesse supérieure à la limite autorisée ou passe au rouge par exemple, une caméra numérique qui prend une vue du véhicule enregistré, un ordinateur qui sauvegarde toutes les données nécessaires, ainsi qu'un dispositif d'éclairage tel qu'un flash, est caractérisé en ce que toutes les unités fonctionnelles excepté le capteur sont mises en mode de veille et s'activent mutuellement ou sont activées par un contrôleur uniquement aux moments nécessaires.
