    [0002] UNIVERSAL DEVICE FOR WIRELESS CAPTURE OF ROAD SIGNAL DATA IN REAL TIME, SOLAR AUTONOMOUS
    [0004] TECHNOLOGY SECTOR
    [0006] The road infrastructure of most countries, the old technology that is not very compatible between different manufacturers of traffic lights and mobility and road safety control systems, does not allow obtaining any real-time data from these systems and infrastructure that were not conceived at the time to interconnect with data with everything that is around it in real time. Traffic lights, for example, in many countries, especially those under development, are old and there is no way to obtain their status and configuration data in real time without changing the entire control system to modern equipment that can communicate with each other, many cities in the world. The world does not have the money to buy high-cost traffic equipment from recognized brands and the latest technology that allows these interconnections of data in real time to share the data with other road users and other signals and traffic lights in real time.
    [0008] Many regulations for safety issues prevent that traffic lights as road safety devices are electrically connected with cables and invasive accessories to obtain information from them in real time, there are many brands, technologies and many different systems so there is no system compatible with all brands regardless of manufacturer, age, type of technology, type of energy they use, etc.
    [0010] Local governments do not allow private persons outside the government to manipulate the electrical circuits and electronic devices of the traffic lights to obtain their operation data, since it represents a risk to road safety and affects the warranty offered by the manufacturer of the equipment.
    [0012] When there is no conventional electrical power or when there is damage to fiber optic or wired networks, it is not possible to have data on what happened with the traffic lights or what their status is, even more so, it is difficult to obtain more complex data in real time such as the time of a traffic light of vehicles or people, the times in their green lights, yellow and red in relation to the time it takes for a vehicle to pass the intersection and reach the pedestrian zone or to a pedestrian crossing or stop sign or calculate simultaneously with the traffic light times based on stopping distance, speed the humidity status of the floor according to the vehicles approaching that point and the time of the traffic light versus pedestrians who want to pass the road the time of the pedestrian traffic light, but ignore when the traffic light changes or if it has already changed and the vehicles are going to stop or not.
    [0014] Nor is there a universal device that allows data to be captured and shared in real time on any traffic light signal without having to intervene and electrically connect the traffic light system or buy a new high-cost one that has these functions, nor is the data shared or displayed. in voice mode on the roads to road users.
    [0016] The proposed invention seeks to obtain a device with a universal shape for any type of signal or traffic light, a very small device, easy to install on all types of signal, lightweight, autonomous with solar energy and integrated speed, humidity and presence sensors, which Regardless of the manufacturer or type of technology, it can read without electrical connection the road signs and time of each of the traffic lights, their programming and other variables of the site in real time through integrated sensors that detect without electrical contact variables in the signal via , sharing that data in real time with other similar devices in other road signs, traffic lights and vehicles where the data is translated into voice messages spoken on the road and then shared to the internet at a very low cost without having to buy new traffic light control equipment or control centers of billions and regardless of whether the traffic lights are old, if they lose power or do not count. still with systems to monitor them.
    [0018] PREVIOUS TECHNOLOGY
    [0020] The traffic signals, vehicular and pedestrian traffic lights, as well as the new traffic light technologies use an internal system incorporated into the traffic light control system and computers to share that data of times and traffic light status to the control centers of the cities that have to be of the same brand and costs of billions of pesos. But at no time do they share these important data with the users of the roads that are close to those sites and They can improve their mobility if they know in advance the status of road signs and other variables.
    [0022] When the power goes out in a sector of the city, the traffic lights turn off and / or the communication systems incorporated into the traffic light that depend on conventional energy stop working, this in those cities that have the budget to have a power plant. high cost control for traffic lights and they are left without knowing what type of failure occurred, whether it was the wired or fiber optic communication system in some part of the city or a total failure of the power or the traffic light system. In any case, the users of the roads that are close to those places never know the data of the traffic signals and they cannot avoid a traffic jam or congestion due to a traffic light without power, damaged or without communication with the control center.
    [0024] Most small or intermediate cities do not have the budget to assemble high-cost technology. Many of these systems are more than 10 or 20 years old and do not even have the option of being able to monitor them from a central office, they must make a visual inspection or wait for an accident or call from the community to go and solve the problem of the traffic lights.
    [0026] Pedestrian traffic lights with sound by means of an audible or luminous signal indicate to people the right moment to pass a road with traffic lights safely, but they do not produce data in real time, nor do they share it with other devices on the roads, with pedestrians or vehicles or with the internet and do not use them for purposes other than monitoring by the cities of the state of the traffic lights and their lights. Not so that nearby drivers and pedestrians know this data in real time avoid congestion and risks.
    [0028] DESCRIPTION OF THE INVENTION
    [0030] The device for wireless data capture for road signs and traffic light programs in real time autonomous solar, arises from the need to have a device with a universal shape and use that can be implemented in any road sign or traffic light, independent of the manufacturer and the type of technology, which without electrical contact with the road signal system or traffic light using optical detection of the lights, can determine the status of the traffic light road signal and the times of programming of the lights as well as other variables of the site, which you can share in order that other road actors near these sites can have access to this data in real time through spoken messages. Wet floor speed sensors for the presence of vehicles and pedestrians complement the reading data of the device that is shared in real time to other nearby similar devices and to the Internet.
    [0032] The device is a single unit in the shape of a very thin and flattened "U", which enters like a clamp on the sheets of the traffic lights that form the hood, visor or protective cap so that the sun's rays do not hit on the traffic lights. Due to the fact that the traffic light caps are standard size, this device can be placed on any type of traffic light, the sides of the "U" are retractable allowing the distance of the legs of the U to be adjusted between 5 to 19 cm. The lower leg of the U that remains on the inside of the traffic light cap is just 3 millimeters thick, so it does not obstruct the visibility of the traffic light.
    [0034] The U-shaped device has integrated a small solar panel, a long-life battery, a microprocessor with communication module, an audio output, a humidity sensor, ccd sensor, optical sensor, presence and speed connected to each other by inside the U and fused into the unit looking like a bulge on the upper leg of the U before the bend. It also has on the upper leg of the U on one of its sides an output and input port for digital and audio signals.
    [0036] The way to use this invention is by inserting the U in the upper part of the sheet of the cap of the road sign or traffic light and securing it with a screw to the traffic light cap, which takes a few seconds, does not require any configuration or electrical connection being ready for use and even installing it without contact with the traffic light, it can detect the status of the lights from several meters away. At the bottom of the U, at the tip that is pointing to the traffic light, there is an optical sensor that monitors the state of the traffic light signal light without electrical contact with the traffic light, nor with its electrical circuit, nor with your data networks, not with your computer, not with your lights.
    [0037] The solar panel provides enough energy for autonomous work during the day, without the need for direct sunlight and even on cloudy days with only daylight and stores excess energy in the battery for night operation. In the upper part of the curve of the U, the sensors and electronic system are embedded which are seen as a protrusion and at the end of the upper part of the U is embedded the small solar panel.
    [0039] During the daily operation of the traffic light and the change of the lights, the microprocessor stores and learns how the lights behave according to the day and time, obtaining the traffic light programming and anticipating when it will change its sequence of lights, simultaneously takes data from the sensors, analyzes them and this set of data sends them to other equal devices that receive the information and reproduce it in the form of a voice, this information is also sent to the internet and has a logic output from the microprocessor through a port on the side. top of the U to activate other light or sound devices or connect external sensors.
    [0041] The device has high energy efficiency, which allows it to work autonomously with a small solar panel even on cloudy days or without only direct and without requiring conventional electrical energy or any type of electrical connection with the traffic light road sign, working universally in any road sign.
    [0043] The same device operates in 2 modes, Master and Slave, the master allows sending the traffic light data to other devices and the slave allows receiving the data sent by the master and reproducing the sound alerts.
    [0045] The orange economy technologies and the fourth industrial revolution or industry 4.0 is based on the power of data to connect and obtain information in real time that allows the efficiency and effectiveness of actions to solve complex and expensive problems, this device seeks to obtain these data from road signs semaphores that due to their age, technology or lack of budget do not have the ability to generate this data and share it.
    [0047] With this device you can obtain data in real time of: The color in which each of the traffic lights is found from centimeters to meters away, the time it takes for each light to be turned on, the days and hours of the week in which that these lights are programmed with different times, obtain the data of whether lights burned out, obtain data on the average speed at that site and if there are vehicles or people present, obtain data on whether the power of the traffic light has gone, regardless of whether the traffic light can transmit data on its status and whether or not it has power electrical. This device economically provides important data both to the city authorities with old traffic lights without monitoring systems, as well as to other people, data in real time that allows anticipating mobility, maintenance and road safety actions, being able to obtain this data without need for conventional electrical energy and regardless of whether the traffic light has energy or not to communicate this data.
