caractérisé par le fait qu'il comporte une carte de détection d'anomalies de circulation (9) programmée avec un ensemble de paramètres permettant de détecter les anomalies, en fonction des seuils et des mesures effectuées par dialogue permanent avec la carte unité logique de traitement (8), la carte de détection des anomalies (9) commande la caméra adéquate (21, 22) et demande la transmission d'images, le calculateur de gestion de communication (31) reçoit l'image, ainsi que les valeurs de comptage associées, le décodage des images est assuré par une carte de détection d'anomalies de circulation (32) interne au poste de gestion central (15), incluant les moyens (24) de restitution d'images qui sont alors restituées sur un moniteur (26) du poste de gestion central (15).2. Device according to claim 1, of the type using a traffic light cabinet (1) comprising: - a supply device (2, 3), - an input / output control device (4) - a logic processing unit card (8) - traffic light / power control cards (10) (11, 12, 13) - a link card (14) with the centralized regulation device (15), - vehicle detectors (17), - cameras (21, 22), - a central management station (15),
characterized by the fact that it comprises a circulation anomaly detection card (9) programmed with a set of parameters making it possible to detect the anomalies, as a function of the thresholds and of the measurements carried out by permanent dialogue with the logic processing unit card (8), the anomaly detection card (9) controls the appropriate camera (21, 22) and requests the transmission of images, the communication management computer (31) receives the image, as well as the count values associated, the decoding of the images is ensured by a circulation anomaly detection card (32) internal to the central management station (15), including the means (24) for restoring images which are then restored on a monitor ( 26) from the central management station (15). 3. Dispositif selon la revendication 1 ou 2, caractérisé par le fait
que la carte (8) est programmée avec un ensemble de paramètres permettant de détecter les anomalies, notamment : - un seuil haut concernant le taux d'occupation de la boucle voie I, - un seuil bas concernant le taux d'occupation de la boucle voie I, - un seuil haut concernant la valeur du débit de la boucle voie I, - un seuil bas concernant la valeurdu débit de la boucle voie I,
et ainsi de suite pour chacune des voies concernées II, III.3. Device according to claim 1 or 2, characterized in that
that the card (8) is programmed with a set of parameters making it possible to detect anomalies, in particular: - a high threshold concerning the occupancy rate of the track I loop, - a low threshold concerning the occupancy rate of the track I loop, - a high threshold concerning the value of the flow rate of the channel I loop, - a low threshold concerning the value of the flow rate of the channel I loop,
and so on for each of the channels concerned II, III.
