Abstract

The installation consists of resistance type photosensitive cell which is placed at the tunnel entrance and generates a voltage inversely proportional to the lighting level. When external sunshine increases, the voltage falls and the relays which have maximum and minimum thresholds adjustable by potentiometer operate successively to close contactors controlling each lamp

Système de pilotage automatique sécurisé de l'éclairage de tunnels
La présente invention concerne un dispositif automatique de commande de projecteurs d'éclairage de l'entrée de tunnels routiers, grâce à un ensemble de capteur, de carte électronique, permettant d'éviter les phénomènes d'éblouissement dus au gradient dans les intensités lumineuses entre l'extérieur et l'intérieur du tunnel. Secure automatic control system for tunnel lighting
The present invention relates to an automatic device for controlling lighting projectors at the entrance to road tunnels, by means of a sensor and electronic card assembly, making it possible to avoid glare phenomena due to the gradient in the light intensities between outside and inside the tunnel.

La présente invention comprend un circuit ayant une entrée 220V, un raccordement sur une cellule photosensible, devant être placée sur un point dégagé de l'entrée du tunnel, de type Résistance photosensible (LDR), et un nombre de sorties ou projecteurs à commander. The present invention comprises a circuit having a 220V input, a connection to a photosensitive cell, to be placed on a point clear of the tunnel entrance, of photosensitive resistance (LDR) type, and a number of outputs or projectors to be controlled.

Dans les schémas qui suivent, nous avons 8 relais, donc 8 lampes possibles. In the diagrams which follow, we have 8 relays, therefore 8 possible lamps.

L'intensité lumineuse extérieure au tunnel est captée et mesurée par la LDR : elle est ensuite comparée aux 8 seuils pré paramétrés, pour chacune des 8 lampes. The light intensity outside the tunnel is captured and measured by the LDR: it is then compared to the 8 preset thresholds, for each of the 8 lamps.

Chaque fois qu'un seuil est dépassé, le relais correspondant est activé et la lampe associée, commandée. Whenever a threshold is exceeded, the corresponding relay is activated and the associated lamp, controlled.

Les seuils sont équidistants, mais peuvent aussi avoir un espacement logarithmique, en changeant la valeur de quelques résistances, permettant de mettre l'accent sur des plages de Lux préférentielles, en fonction de la physiologie humaine. The thresholds are equidistant, but can also have a logarithmic spacing, by changing the value of some resistances, allowing to focus on preferential Lux ranges, depending on human physiology.

Chaque relais est muni d'un circuit RC, réduisant les phénomènes d'étincelle, ce qui prolonge la durée de vie du contact. Each relay is fitted with an RC circuit, reducing sparking phenomena, which prolongs the life of the contact.

L'intensité lumineuse extérieure au tunnel captée par la LDR est convertie en tension interne, inversement proportionnelle, c'est à dire, si la lumière augmente, la tension interne diminue et inversement. The light intensity outside the tunnel captured by the LDR is converted into internal voltage, inversely proportional, that is, if the light increases, the internal voltage decreases and vice versa.

La LDR est sensible à une gamme étendue de luminosité allant de la lumière de la Lune (O. lLux), au plein soleil (30 000 Lux), en passant par une lampe de 60W à lm (50Lux). The LDR is sensitive to a wide range of luminosity going from the light of the Moon (O. lLux), in full sun (30,000 Lux), passing by a lamp from 60W to lm (50Lux).

Le Schéma (1) montre le déclenchement successif des 8 lampes par les 8 relais en fonction de l'intensité lumineuse externe au tunnel. The Diagram (1) shows the successive triggering of the 8 lamps by the 8 relays according to the light intensity external to the tunnel.

La sécurité dans les tunnels, peut donc être très largement améliorée par l'intégration de la présente invention. Sur tout le linéaire du tunnel, le même dispositif permet de conserver un niveau d'éclairement correspondant à celui de la nuit, de 50Lux à 100Lux ou plus, sans éblouïssement, de façon permanente.  Safety in tunnels can therefore be greatly improved by integrating the present invention. Throughout the entire length of the tunnel, the same device makes it possible to maintain a level of illumination corresponding to that of the night, from 50Lux to 100Lux or more, without glare, permanently.

Le dispositif s'adapte parfaitement à l'ensemble des tunnels existants, y compris les galeries souterraines diverses. The device adapts perfectly to all existing tunnels, including various underground galleries.

Les réglages initiaux du système sont réalisés grâce aux deux potentiomètres multi- tours PI et P2 : pour augmenter un seuil pour chaque relais, il faut tourner dans le sens des aiguilles d'une montre ; pour diminuer, dans le sens inverse. The initial system settings are made using the two multi-turn potentiometers PI and P2: to increase a threshold for each relay, turn clockwise; to decrease, in the opposite direction.

Le seuil mini de tension interne correspond au seuil maxi de la lumière captée par la LDR. Si la lumière augmente, la tension interne en volt diminue (variation de 2V à 22V). Au fur et à mesure que la tension interne descend en dessous des seuils, les relais correspondants se relâchent. Donc l'allumage d'un projecteur avec lumière extérieure croissante pourra se faire par le contact NC (Normally Closed) du relais pour commander le contacteur de puissance alimentant ce même projecteur. Si à l'inverse on veut éteindre un projecteur avec la lumière externe croissante, le contact NO (Normally Open) sera actionné.The minimum internal voltage threshold corresponds to the maximum threshold of the light captured by the LDR. If the light increases, the internal voltage in volts decreases (variation from 2V to 22V). As the internal voltage drops below the thresholds, the corresponding relays release. So the lighting of a projector with increasing exterior light can be done by the NC (Normally Closed) contact of the relay to control the power contactor supplying this same projector. If, on the other hand, we want to switch off a spotlight with increasing external light, the NO (Normally Open) contact will be activated.
