Orientable information support system Technical field and state of the art In the field of information display, especially around road traffic lanes, it is known in particular systems adapted to display one or more information, possibly in alternation, with a change of information if necessary at predefined intervals of time.

It is admitted, however, that the information posted may distract a motorist, a cyclist, a pedestrian or, more generally, any person looking at the information displayed; This can be dangerous if the user of the traffic lanes is not attentive enough to his environment. DESCRIPTION OF THE INVENTION The invention proposes a new animated information support system that does not have the drawbacks of existing systems. More specifically, the invention proposes a new information support system comprising: a display panel comprising means for displaying information - orientation means for orienting the panel in a first direction or in a second direction; function of a control signal, - a detection device for detecting a stopped or moving state of a person in the vicinity of the display panel and - a control device adapted to produce the control signal in accordance with a stopped or moving state detected. The person in the vicinity of the billboard may be any person likely to be stationary or moving near the billboard, and in particular: - a motor vehicle such as a moped, a car, a car bus, etc., in which there is at least one person, - a person on foot, by bike, etc. With a system according to the invention, the orientation of the panel, and therefore the direction in which the information displayed by the panel is visible, is a function of the stopped or moving state of the person in the vicinity of the billboard for example on a taxiway. Thus, the user can consult the information displayed only when he is motionless, and is not distracted while he is moving. The system according to the invention also makes it possible to better target the display of information according to the actual situation, and no longer to the public, for which it is intended. The system according to the invention also makes it possible to better respond to the regulations of certain countries, in particular France and Europe, which prohibit the display of advertising information for moving vehicles in the vicinity of zones. crossing.

The detection device is for example adapted to detect a color of a traffic light; the control device in this case produces the control signal if the detected color of the traffic light corresponds to a person stop instruction (red). The information displayed on the sign is thus visible only to those stopped on the taxiway. According to one embodiment, the color detection device comprises an imaging device, for example a camera, provided with image processing means for recognizing a color of the traffic light and detecting moments of color changes. from the said traffic light. The device is thus totally independent of the traffic lights: the system according to the invention is not likely to disturb the operation of the traffic lights, and it is not disturbed by a possible malfunction of a traffic light management system. .

According to one variant, the detection device comprises an image taking device, for example a camera, for taking successive images at predefined time intervals, and image processing means for detecting a stopped state of an image. nobody in successive pictures; the control device in this case produces the control signal if a stopped state is detected. According to another variant, the color of the fire and the stopped state of the persons are detected, and the control device produces the control signal if the detected color of the traffic light corresponds to a stop instruction of the persons (red) and if a stopped state of a person is detected. According to another variant, the detection device is a device for detecting GPS signals transmitted by an electronic device of a user of the public space, for example a mobile phone or a GPS navigation device, provided with processing means signal to identify a place of emission of signals and deduce a stopped or moving state of the electronic device. To be orientable, the display panel is rotatably mounted relative to the ground. Alternatively, the display panel is attached to an upper end of a mast rotatably mounted relative to a grounded mast foot, and wherein the orientation means comprises means for rotating the mast by compared to the foot of the mast. The means for rotating the mast is for example a motor coupled to a gearbox. Thus the mast and the panel are rotated relative to the mast foot. The advantage of this solution is its technical ease of installation and maintenance because a part of the installation, the rotating drive means in particular, can be installed on the ground or near the ground. This solution is preferred for small panels that can be fixed on small masts, for example less than six meters. According to another variant, the display panel is rotatably mounted at an upper end of a mast, and the orientation means comprises means for rotating the panel relative to the mast according to the control signal. The means for driving the rotating panel is for example a motor coupled to a gearbox, all installed at the top of the mast next to or on the panel. The advantage of this solution is its robustness, in particular with respect to vandalism, since the most fragile elements of the system, in particular the panel, the rotation drive means, the control device, are installed in height and are therefore more difficult to access. This solution is preferred for large panels (much more expensive than small panels), which can be installed on taller masts and positioned further from the traffic lanes. In a version adapted to a crossroads of at least two lanes, crossroads equipped with a first signaling light adapted to alternatively authorize or prohibit traffic on a first lane and a second traffic light adapted to prohibit or alternatively authorizing traffic on a second lane according to the color of the first light, the device for detecting a color of a light may be rotatably mounted between: a first direction pointing to the first light or to the first lane; traffic, and - a second direction pointing to the second traffic light or to the second traffic lane.

In a variant, the detection device comprises two imaging devices, one pointing towards the first light and the other pointing towards the second light. The control signal produced is then a combination of the signals produced by each image pickup device. This version allows to take into account a possible failure of one of the traffic lights. Finally, the signaling panel may also comprise means of connection to an external communication network, for example the Internet network, in particular for receiving a plurality of information to be displayed and criteria for selecting one of the plurality of information items. information according to a panel orientation. This allows a regular updating of the information that may be displayed on the panel, and display on the panel relevant information depending on the position of a user likely to look at the panel, the direction it takes , places he is likely to approach in the chosen direction, etc.
