BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a road safety installation with emission of sound messages.
A driver driving a motorvehicle is guided on his way by signalling panels bordering the road. The driver is therefore obliged to remain very attentive to the signalling panel and to their signification, in order to drive carefully and thus to avoid to a maximum all risks of accidents. The driver must also now and again look at his speedometer, in order not to exceed the authorized speed limits, and at his rearview mirrors in order to keep a watch on the traffic behind his vehicle. Because of these various obligations, it is obvious that the various signalling panels warning of danger, stop, or right of way, for example, are sometimes overlooked for a number of reasons. It is therefore of the greatest importance, to warn the driver of a vehicle against any situation or danger already materialized by a fixed signalling panel.
SUMMARY OF THE INVENTION
The installation according to the invention has been designed to this effect, and its object is to give the driver a maximum of information by sound means, due to a particularly simple combination of means.
To this effect, the road safety installation according to the invention with emission of sound messages is characterized in that it comprises, for every type of signalling panel fixed along a road, a device emitting a coded infrared radiation signal corresponding to the type of signalling panel to which it is associated and, on every vehicle circulating along the road, a device receiving the coded infrared radiation signal delivered by the fixed emitter device and converting it into a clear sound message emitted for the attention of the driver of the vehicle, the emitter device comprises a source of power feeding, via an encoder, an infrared radiation emitter, so that the device delivers, in the direction of the vehicles arriving on the road, a coded infrared signal, and a sound level detector or sound sensor which controls a normally open switch which is closed in order to start the emitter device in operation, when the sound sensor perceives the noise emitted by the engine of a vehicle, and the receiver device comprises an infrared radiation sensor which is mounted on the vehicle, at the front part thereof, inside or outside, said sensor being connected to a decoder of which the output is connected to a selector of the appropriate sound message.
BRIEF DESCRIPTION OF THE DRAWINGS
One embodiment of the invention is described hereinafter, by way of example and non-restrictively, with reference to the accompanying drawings in which:
FIG. 1 is a block diagram of an emitting road safety installation according to the invention.
FIG. 2 is a perspective view of a coded infrared radiation emitter used in the installation according to the invention.
FIG. 3 is a vertical section along line III--III of FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The installation according to the invention which is diagrammatically illustrated as a whole in FIG. 1, comprises, for each type of signalling panel fixed along a road, a device 1 emitting a coded infrared radiation signal i corresponding to the type of signalling panel P to which it is associated and, on each vehicle 2 circulating on the road, a device 3 receiving the coded infrared radiation issued from the fixed emitter device 1 and converting it into a clear sound message delivered for the attention of the driver of the vehicle. For example, in the case illustrated by way of example in FIG. 1, the emitter device 1 is associated to a "STOP" panel and the coded infrared radiation signal, once it has been decoded in the receiver device 3, becomes a clear sound message which can be as follows: "compulsory stopping. Failure to comply will entail a risk of fine and of withdrawal of the driving license".
The emitter device 1 comprises an autonomous source of power 4, such as a battery or a solar cell, or it can also be connected to the mains electrical supply if the position of the panel allows it.
