Definitions
- the present invention relates to a signaling device adapted to be triggered to warn of the crossing by a living being, for example a pedestrian, of traffic lanes.
- these signaling devices are of the type comprising first and second light devices arranged on either side of the tracks, and it requires intervention by a pedestrian to trigger them.
- the invention on the contrary, relates to a device adapted to warn of the crossing of a pedestrian, or of any living being, without direct intervention of the latter.
- the present invention provides for this purpose a signaling device to warn of the crossing by a living being of traffic lanes of the type comprising at least a first light volume disposed near these lanes; and comprising: at least one automatic detection device for the presence of this living being in the vicinity of these paths, adapted to cause, at least indirectly, the illumination, for a predetermined duration, of a light volume; - a transmission device controlled by the detection device for sending a signal of determined frequency; a device for receiving control of this signal, located close to these channels, tuned to the frequency of the transmitting device; and adapted to trigger the illumination, for said predetermined duration, of this light volume which is therefore illuminated each time the presence of a living being is detected by the detection device.
- This arrangement makes it possible to trigger the flashing of a light volume, for example at the right of a "pedestrian crossing" (on one side and / or the other of the roadway, and / or above it) without a pedestrian, who crosses, having to voluntarily make a pressure movement so as not to instill in him a false impression of security.
- This device can, of course, activate a greater number of light volumes.
- the device of the invention comprises two identical sets, arranged on either side of traffic lanes, each comprising:
- a light volume preferably flashing; a barrier for detecting the passage or presence of a living being;
- an interactive transceiver device a signal of determined frequency on either side of the channels.
- This arrangement has the great advantage of being very simple to implement.
- the device according to the invention comprises several timers connected respectively to the devices for controlling the light volumes and to the emission and detection devices; this timer connected to the detection device generating a detection invalidation signal for a time equal to the average time a crossing of the road by a pedestrian.
- This arrangement prevents a pedestrian from being redetected by the second detection device after crossing the road.
- the device according to the invention comprises a timer linked to the light volume control device which generates a control signal for a time equal to twice the average time a crossing of the road by a pedestrian.
- FIG. 1 represents a schematic side view of the device of the invention
- 2 shows a schematic view of the device of the invention according to arrow II of the figure
- FIG. 3 represents a block diagram of the electronic control circuit of the device according to the invention
- FIG. 4 represents a chronogram of operation of the circuit represented in FIG. 3.
- the device of the invention comprises two identical sets arranged on either side of a floor 10.
- the identical elements of the two sets are numbered in the same way, being assigned suffixes a and b respectively.
- Each set includes: - a flashing light volume 11a (11b) placed at the top of a pole 12a, (12b); - An automatic detection device 13a, 14a, (13b, 14b) of the presence of a pedestrian 15 on one side of the roadway 10, adapted to cause, at least indirectly, the illumination for a predetermined period, of the 'one of the light volumes 11a (11b) associated therewith.
- the detection device comprises a photoelectric barrier, that is to say, for example, an element 13a (13b) light emitter-receiver, for example infrared, located on the post 12a (12b), and a light reflecting element 14a (14b), which faces it, arranged on another post 17a (17b), at the same height as the first element 13a, (13b).
- the two posts 12a and 17a (12b and 17b) are arranged along the road, on the sidewalk 18a (18b); two barriers 19a and 20a (19b and 2.0b), are, in the embodiment shown in Figure 2, arranged on either side of these two posts 12a and 17a (12b and 17b), to channel the passage of pedestrians ( 15) wanting to cross pavement 20 on the pedestrian crossing.
- each flashing volume 11a (11b) comprises in its upper part an inclined plane 21a (21b) on which is disposed, for example, a solar panel.
- each flashing volume 11a (11b) comprises in its upper part an inclined plane 21a (21b) on which is disposed, for example, a solar panel.
- the electrical control circuit of each of the two sets of the device of the invention therefore comprises a solar panel 25 coupled to two batteries 26 and 27, a charge regulator 28, a transmitter 29 and a receiver 30 of a determined frequency signal; an emitter-detector 13 of an optical signal, shown before in FIGS. 1 and 2 in front of a reflector 14, a device 31 for controlling intermittent illumination of a lamp 32 and several timers 33, 34, 35 connected respectively to the transmitter 29, to the transmitter-detector 13 and to the control device 31.
- the transmitter-detector 13 is connected by an output to the first timer 33 and the receiver 30 to the second and third timers 34 and 35.
- the solar panels 25 make it possible to transform light energy into electrical energy allowing the batteries 26 and 27 to be charged. They are directed towards the south and inclined in the direction of the sunshine.
- the charge regulator 28 known to those skilled in the art has the function of maintaining the correct charge of the batteries 26 and 27 in an optimal operating range between a maximum threshold and a minimum threshold, thus avoiding overcharging and deep discharge of these.
- the operation of this electrical circuit is illustrated on the timing diagram of FIG. 4 in which: the signal S1 represents the signal received during the detection by the detector 13 of the passage of a pedestrian 15 between the two posts 12 and 17; the signal S2 represents the signal emitted by the transmitter 29; the signal S3 represents the signal transmitted by the receiver 30 to the timers 34 and 35; - signal S4 represents the detector disabling signal, at the output of timer 34; signal S5 represents the lamp control signal 32.
- the first corresponding transmitter 29 transmits a signal S5 for the time necessary so that the first receiver 30 can receive this signal.
- Each receiver 30 then transmits a pulse S3 to the timers 35 which respectively authorize the flashing of the two lamps 32 supplied by the two control devices 31 and the inhibition of the two detectors 13 for a certain period of time.
- a pulse (S1) received by the detector 13 controls the operation (S2) of the transmitter 29 whose signal is received by the receiver 30.
- the timer 34, controlled by this receiver 30 invalidates the detector 13 for a time equal to the mean time a, of crossing the roadway by a pedestrian which prevents the pedestrian from being detected again after having crossed the roadway and that the system is thus rebooted .
- the timer 35 linked to the receiver 30 controls the flashing of the lamp 32 for a determined time. Due to the invalidation of the detector 13, the second pulse, shown in FIG. 4, detected in S1 is therefore not taken into account.
- the third pulse detected is taken into account and causes a re-ignition 40 of the lamp control device 32.
- the flashing time of the lamp 32 is close to 2a, which prohibits a new reboot of the device if two pedestrians follow each other, spaced a time less than a.
- the volumes can blink using optical fibers, the first ends of which are coupled to a lamp and the second ends of which form a particular pattern against a side wall of the light volume visible by the conductors traveling on the nearest path.
- This flashing can also be done by means of light-emitting diodes, plasma plates, incandescent or fluorescent lamps.
- a panel provided with a particular design, for example that of a pedestrian, can, moreover, be placed in front of these light elements to form this side wall of said light volume.
- the device of the invention can be powered using batteries, from the mains or any other energy supply.
- the two flashing assemblies illustrated in FIG. 2 have been shown arranged on either side of the "pedestrian crossing” materialized on the road, but they could just as easily have been arranged on the same side of this "crossing for pedestrians ".
- the light volumes can, of course, be continuously lit when a pedestrian is detected.
- the detection of the pedestrian, or of any living being can, of course, be done by photoelectric, microwave, ultrasonic, infrared light, or any other presence detection device.
