PEDESTRIAN TRAFFIC LIGHT WITH AUTONOMOUS ENERGY

Abstract

This invention is in the field of electricity and electronics, it focuses on reducing the risk of traffic accidents in people with visual or other disabilities who try to cross a road when there is no power or there is no one to guide them. To solve this problem, this device is proposed to be used in public spaces and roads. Characterized by a solar panel (3), some lamps (1), a mast (2) and housing (4) with sensors infrared, CCD, time of flight sensors, and mechanical sensors that are connected to the processor and connected to one audio output elements that gives spoken messages of risk to pedestrians, with energy autonomy and disconnected from the electricity grid.

[0030] FIG. 2: Is a diagram illustrating interaction between solar panel (3), battery (5), at least one lamp (1), communication module (7), and electronic circuits (6).

[0031] FIG. 3: Is an exemplary block diagram illustrating the connection of the communication module (7), the electronic circuits (6), the at least one lamp (1) including light emitting diodes (LEDs) (9)

[0032] FIG. 4: Is a block diagram of electronic circuits shown in FIG. 3. The electronic circuits (6) having optical sensor (11), infrared sensor (12), charge-coupled device (13), lidar sensor (14), infrared time of flight sensor (15), mechanical sensor (16) all connected to a processor (8) connected to an audio output element (17).

BEST WAY TO REALIZE THE INVENTION

[0033] This invention is made by putting a metal or plastic mast (2) on a sidewalk or mast (2) with or without arm with height between 2 to 9 meters and 2 to 25 centimeters in diameter that can be totally circular or with polygon type edges including the dodecagon and the square, at the top of the mast (2) or arm a solar panel (3) is placed and secured with a plurality of means of grip such as screws, pins or guayas. From the solar panel (3) a cable is connected to the pedestrian traffic lights where the electronic circuit (6), audio, sensors and battery (5) are located and in the front are the lamps (1) that emit light in a plurality of colors, which operate at voltages between 3 Volts and 40 Volts DC in pulses or in AC and that are arranged facing the tracks, to sidewalks or pedestrian crossings, if the batteries do not fit in the traffic light housing (4), an external housing can be used to put batteries and circuits (6) there. Electrical connections are made to the previously charged battery (5) and between the components and a traffic light is ready that can operate autonomously with solar energy and with additional accessory functions such as talking to pedestrians and transmitting information among others. Being able to operate as an accessory but not indispensable in a hybrid way with energy from the grid to charge the batteries or give direct energy to the electronic components and use renewable energy to reduce consumption or serve as support when the grid power fails. But without abandoning that the main purpose and the most important technical advantage that arises is the totally autonomous operation reducing to zero the consumption of the electrical network and without the need to consume energy from the network.
