FR2826488A3 - Automatic solar powered safety control for pedestrian crossings has automatic activation of lights and video recording to provide evidence if accident occurs - Google Patents

Abstract

The automatic solar powered safety control for a pedestrian crossing has a vehicle detector embedded in the road, which triggers an electronic management system to illuminate optical fibre lamps which signals the vehicle and display arrival of the vehicle. Video recording is automatically activated to provide evidence in event of an incident. The system is powered by a solar charged battery with a charging regulator.

Technical description.

The present invention is located in the technical fields of video surveillance but also of road movement detection as well as that of security.

The different techniques prior to this invention are the passages protected by nail or by marking on the ground with paint or else by the lighting system of the pedestrian passages by interactive terminals but none using optical fiber coupled to solar panels also coupled with a video recording of the facts taking place when the complete system is triggered and none of them also had a buried detection system on the ground of the vehicle as well as led panels signaling the danger by opposite way, the technical problem posed here was therefore to create an autonomous system managed by a microcontroller having an energy capacity allowing it to self-manage and to include a buried ground detection as well as the management of LED panels indicating presence in reverse position all this at night. I therefore created the autonomous solar security system for pedestrian passage with video recording having the following elements: it is characterized in that it consists of five parts, a first being characterized by the electronic management of the system also comprising a timer serving to limit the duration of lighting of optical fibers also consisting of another part s characterized by a bundle of optical fiber used for lighting the sensitive site also consisting of a video surveillance system itself composed of two micro cameras as well as a cyclic switch also made up of an autonomous management and energy system itself made up of solar panels as well as a charge regulator and an accumulator also made up of light panels used to warn of danger the reverse side of the place to be protected, these panels also used for advertising messages for the nearest town consisting of an electronic management system itself composed of a timer and a microcontroller used for the operation of the concept consisting of a plastic fiber optic lighting system and connector for optical fiber as well as a transceiver for optical fiber, characterized in that a video surveillance system itself composed of them micro-camera as well as a cyclic switch allow to film all actions which are triggered by the road motion detector as well as a mechanical recorder consisting of a road motion detection system placed on the road and buried in it, thus allow via electronic management to control the lighting of the optical fibers and therefore the desired location characterized in that an operating autonomy management itself is made up of charge regulator and servo accumulator solar panels t operating independently from the system of the present invention, characterized in that two LED light panels carrying a safety message are installed on the opposite side of the safety system in order to establish prevention by light display.

In order to understand how this system works, I describe below the embodiment: in a traditional crossroads have implanted at a legal distance of a stop 150 meters a lighting system by optical fiber (b) which will be triggered by the road motion detector (a) when a vehicle passes over it, on the other side of the road have installed in reverse position two light signaling panels (c), at the level of the motion detector (a) also place the electronic management system as well as the solar panel used for the autonomy of the system, and of course the video system

 Technical description (continued) monitoring. When a vehicle arrives at the buried motion detector (a) the electronic management records the passage and immediately triggers the lighting of the stop sign which is marked by optical fibers (b), in the same period of time the warning signs ( c) placed in the opposite position to the general layout, displays a message stating that a vehicle arrives at the stop, and as soon as the detection records the movement, the video surveillance system records the events taking place, the solar panel serving it thanks to its accumulator to store energy so as to restore it at night, so that this system is operational after dark.

The application of this invention is also intended for town halls, DDE, all communities but also all legal persons wishing to carry out security protection for these vehicle exits, and of course the individual.

Description of figure number 1: describing the implementation of the concept on a road with a crossroads: - a- underground vehicle detection system, as well as electronic management and solar power panels.

 - b- fiber optic lighting system - c-luminous display panels positioned in reverse of the basic concept of this invention.
