Abstract

The display (1) includes a speed limit information display (2) and two weather information displays (3) all supplied by a battery or a transformer. The displays are controlled by CMOS logical circuits. A humidity sensor (4) is placed on the road surface (7) and connected to the control circuits. A fog detector, which includes a receiver (5) and photoelectric emitters, is connected to the control circuits.

Description

La présente invention concerne un dispositif d'affichage lumineux servant de panneau de signalisation sur routes et autoroutes, adaptant la vitesse annoncée aux conditions climatiques. The present invention relates to a luminous display device serving as a traffic sign on roads and motorways, adapting the advertised speed to climatic conditions.

Actuellement, les panneaux indicateurs ne sont pas adaptés au fait que la météorologie change continuellement. Ainsi, les panneaux de signalisation indiquent une mauvaise vitesse s'il pleut ou s'il y a du brouillard. Currently, the signs are not adapted to the fact that the weather is constantly changing. Thus, the traffic signs indicate a bad speed if it is raining or if there is fog.

Le dispositif selon l'invention permet de remédier à ces inconvénients. En effet, comme il est possible de le voir page 1/1, le panneau lumineux (1) est composé de trois parties: un panneau indicateur de vitesse (2) et deux affichages d'informations (3). Alimenté par une batterie ou un transformateur (8), le dispositif est géré par des circuits intégrés électroniques de génération
CMOS logique. Un capteur d'humidité (4), placé sur le revêtement de la chaussée (7) permet de déceler si la route (7) est mouillée. De plus, un détecteur de nébulosité, composé d'un récepteur (5) et d'émetteurs (6) photoélectriques ou infra-rouge permettent de détecter la présence de brouillard, par baisse de visibilité relative.The device according to the invention overcomes these drawbacks. Indeed, as it is possible to see on page 1/1, the light panel (1) is composed of three parts: a speedometer panel (2) and two information displays (3). Powered by a battery or a transformer (8), the device is managed by electronic generation integrated circuits
Logical CMOS. A humidity sensor (4), placed on the road surface (7) makes it possible to detect whether the road (7) is wet. In addition, a cloud detector, composed of a receiver (5) and photoelectric or infrared emitters (6) can detect the presence of fog by decreasing relative visibility.

Ainsi, les circuits électroniques permettent de gérer la priorité de l'information donnée et d'afficher la vitesse et les informations adéquates sur le panneau lumineux. Thus, the electronic circuits make it possible to manage the priority of the information given and to display the speed and the adequate information on the light panel.

Par conséquent, I'automobiliste reçoit toujours l'information adaptée aux conditions climatiques. Consequently, the motorist always receives information adapted to the climatic conditions.

Selon les modes de réalisation: - le panneau peut être à double face, donnant ainsi les informations aux automobilistes roulant dans les deux sens. According to the embodiments: - the panel can be double-sided, thus giving information to motorists driving in both directions.

- la taille du panneau lumineux peut être adaptée suivant la configuration du site.- the size of the light panel can be adapted according to the configuration of the site.

- les textes d'informations peuvent être adaptés suivant la demande.- the information texts can be adapted according to the request.

- le nombre de capteurs est adaptable suivant les différentes configurations de sites.- the number of sensors is adaptable according to the different site configurations.

- le dispositif peut être installé sur tout terrain, I'alimentation pouvant être gérée par le biais d'une batterie ou, si le site d'installation est équipé d'une alimentation, à travers un transformateur fournissant le courant et la tension électriques nécessaires à la configuration installée.- the device can be installed on any ground, the power supply can be managed by means of a battery or, if the installation site is equipped with a power supply, through a transformer supplying the necessary electric current and voltage to the installed configuration.

Le dispositif selon l'invention est particuliérement destiné à la signalisation routiére et autoroutière, en ce qui concerne l'affichage de la vitesse conseillée et les informations de sécurité nécessaires suivant la configuration météorologique.  The device according to the invention is particularly intended for road and motorway signaling, as regards the display of the recommended speed and the necessary safety information according to the meteorological configuration.
