Estado de la tecnicaState of the art
Respecto al uso del dispositivo en semaforos, en la tecnica se reconoce ampliamente desde hace mucho tiempo la necesidad de dotar a los semaforos de capacidades acusticas para ayudar a las personas invidentes a cruzar las calles. Dichos semaforos emiten senales que indican a estas personas que el semaforo se encuentra en verde y por tanto pueden comenzar a cruzar la calle. Se han propuesto varias soluciones alternativas a esta solucion.With regard to the use of the device in traffic lights, the need for providing traffic lights with acoustic capabilities to help blind people to cross the streets has been widely recognized for a long time. These traffic lights emit signals that indicate to these people that the traffic light is green and therefore can begin to cross the street. Several alternative solutions to this solution have been proposed.
En primer lugar, existen muchos semaforos acusticos que emiten un sonido con un tono especlfico para indicar que el semaforo esta en estado verde, indicando que la persona puede cruzar la calle. En algunos casos, estos semaforos tambien emiten un tono especlfico distinto indicando que el semaforo esta en rojo y por tanto no puede cruzarse la calle, aunque as! ayudan a la persona invidente a localizar la situacion del cruce. Estos sistemas presentan el inconveniente de que suponen una contamination acustica importante que puede generar malestar y protestas por parte del resto de transeuntes y el vecindario de la zona, ya que funcionan de manera constante aunque no sea necesario. Ademas, durante ciertas horas (por ejemplo por la noche) estos sistemas se desactivan completamente, de modo que no ofrecen ningun servicio a las personas invidentes que lo necesiten.First, there are many acoustic traffic lights that emit a sound with a specific tone to indicate that the traffic light is in a green state, indicating that the person can cross the street. In some cases, these traffic lights also emit a different specific tone indicating that the traffic light is red and therefore the street cannot be crossed, although! They help the blind person to locate the crossing situation. These systems have the disadvantage that they imply an important acoustic contamination that can generate discomfort and protests on the part of the rest of passers-by and the neighborhood of the zone, since they work in a constant way although it is not necessary. In addition, during certain hours (for example at night) these systems are completely deactivated, so that they do not offer any service to blind people who need it.
Tambien existen sistemas tactiles como alternativa a los semaforos acusticos. Estos sistemas comprenden un dispositivo ubicado en el poste del semaforo que vibra para indicar si el semaforo esta en verde, de modo que la persona invidente sabe que puede cruzar la calle. Aunque este sistema soluciona los inconvenientes planteados anteriormente, tambien plantea otras muchas desventajas. Por ejemplo, el usuario debe tocar el dispositivo en cada cruce, con los riesgos higienicos y de salud que ello conlleva. Ademas pueden existir obstaculos entre la persona y el dispositivo que impidan que la persona invidente llegar adecuadamente al mismo, tales como por ejemplo otros transeuntes. Por ultimo, estos semaforos no aportan ninguna information a la persona invidente sobre la position de los semaforos y la direction en que debe cruzar.There are also tactile systems as an alternative to acoustic traffic lights. These systems comprise a device located on the traffic light pole that vibrates to indicate if the traffic light is green, so that the blind person knows that they can cross the street. Although this system solves the drawbacks outlined above, it also poses many other disadvantages. For example, the user must touch the device at each junction, with the hygienic and health risks that this entails. There may also be obstacles between the person and the device that prevent the blind person from getting there properly, such as other passersby. Finally, these traffic lights do not provide any information to the blind person about the position of the traffic lights and the direction in which they should cross.
Tambien existe una serie de sistemas bajo demanda, en los que el semaforo acustico tan solo emite sus indicaciones acusticas cuando un usuario lo solicita mediante un mando a distancia especlfico. Aunque este sistema soluciona los problemas planteados anteriormente, presenta el inconveniente de que el usuario debe disponer de un mando a distancia especlfico y debe activarlo expresamente cada vez que desee realizar un cruce.There are also a series of systems on demand, in which the acoustic traffic light only emits its acoustic indications when a user requests it through a specific remote control. Although this system solves the problems outlined above, it has the disadvantage that the user must have a specific remote control and must activate it expressly every time he wishes to make a crossing.
Por ultimo, existe un sistema en el cual mediante comunicacion inalambrica el invidente puede activar mediante su telefono movil un dispositivo de indication acustica situado enFinally, there is a system in which, through wireless communication, the blind person can activate an acoustic indication device located in his mobile phone

el semaforo que emitira un primer tono indicativo del estado verde del semaforo para indicar a las personas invidentes que pueden cruzar la calle. Ademas el sistema facilita information adicional sobre la arquitectura del cruce tal como el numero de carriles, si existe mediana, nombre de la calle, puntos de interes proximos, etc... Esta informacion debe ser solicitada de forma expresa desde el telefono movil. El sistema tambien dispone de un segundo tono indicativo del estado rojo del semaforo distinto del tono que indica el verde. Aunque este sistema soluciona los problemas planteados anteriormente, presenta el inconveniente de seguir necesitando de la existencia de avisadores acusticos en los semaforos para la indication del estado lumlnico del cruce. Ademas no proporciona informacion del estado lumlnico del cruce cuando el semaforo esta verde intermitente ni cuando el semaforo esta averiado.the traffic light that will emit a first tone indicative of the green state of the traffic light to indicate blind people who can cross the street. In addition, the system provides additional information on the architecture of the crossing such as the number of lanes, if there is a median, name of the street, nearby points of interest, etc ... This information must be expressly requested from the mobile phone. The system also has a second tone indicative of the red state of the traffic light other than the tone indicated by the green. Although this system solves the problems outlined above, it has the disadvantage of continuing to need the existence of acoustic warning lights in the traffic lights for the indication of the light state of the crossing. In addition, it does not provide information on the light state of the junction when the traffic light is flashing green or when the traffic light is broken.
Por lo tanto, sigue existiendo en la tecnica la necesidad de un sistema que facilite toda la informacion necesaria en tiempo real que precisan las personas invidentes en cruces con semaforo que se active a distancia y que no precise de la necesidad de ningun avisador acustico instalado en el semaforo.Therefore, there is still a need in the art for a system that provides all the necessary information in real time required by blind people at traffic lights that are activated remotely and does not require the need for any acoustic warning system installed in the traffic light.
Respecto al uso del sistema para dar informacion adicional a las personas invidentes con la que puedan orientarse en zonas urbanas, en la tecnica se reconoce ampliamente de la necesidad de dotar al entramado urbano de un sistema de orientation para las personas invidentes.Regarding the use of the system to provide additional information to blind people with whom they can find their way in urban areas, the technique widely recognizes the need to provide the urban framework with a guidance system for blind people.
Existen dispositivos gps que facilitan la movilidad de este colectivo por las ciudades, pero tienen la desventaja de no facilitar informacion sobre obstaculos ocasionales o temporales como pueden ser terrazas de bares o vallas de obra.There are GPS devices that facilitate the mobility of this group through the cities, but they have the disadvantage of not providing information about occasional or temporary obstacles such as bar terraces or work fences.
Por lo tanto, sigue existiendo en la tecnica la necesidad de un sistema que facilite informacion adicional y en tiempo real a las personas invidentes para que puedan orientarse y desplazarse con seguridad en zonas urbanas.Therefore, there is still a need in the art for a system that provides additional information in real time to blind people so that they can orient themselves and move safely in urban areas.

En el caso de que el dispositivo este situado en un semaforo de peatones se emitira un mensaje nuevo al telefono movil que ha solicitado informacion en cuanto el estado lumlnico del semaforo de peatones varle con lo que se consigue tener informacion en tiempo real.This device, when it receives the request for information from the user's mobile phone (1), processes the necessary signals through the microcontroller (4) and sends the corresponding information stored on the memory card (7) through the bluetooth transmitter ( 5) to the user's mobile phone (1). In the event that the device is located in a pedestrian traffic light, a new message will be issued to the mobile phone that has requested information as to the light status of the pedestrian traffic light varies with which it is possible to have information in real time.
- Telefono movil (1):- Mobile phone (1):
Mediante una aplicacion de movil el usuario podra seleccionar la informacion que desea recibir del dispositivo (2) (estado lumlnico del semaforo de peatones, informacion adicional en cruces como existencia de mediana o longitud del cruce, vallas de obra, existencia de terrazas...) sobre el entorno y la manera en que quiere recibirla (Mensajes orales, codigo de melodlas o codigo de vibraciones).Through a mobile application, the user can select the information they wish to receive from the device (2) (pedestrian traffic light status, additional information at crossings such as existence of median or length of the crossing, work fences, existence of terraces ... ) about the environment and the way you want to receive it (oral messages, code of melodlas or code of vibrations).
Ejemplos de modo de realizacionExamples of embodiment
A continuation se exponen unos ejemplos de realizacion de la invencion que no es limitativo a su alcance:Below are some examples of realization of the invention that is not limited to its scope:
Si el usuario va desplazandose por la calle y tiene activada en la aplicacion de movil la reception de informacion del estado lumlnico del semaforo de peatones, cuando se aproxime a un cruce, la senal emitida mediante tecnologla bluetooth por su telefono movil sera recibida por el modulo bluetooth del dispositivo situado en el semaforo, entonces el microcontrolador del dispositivo procesara las senales del semaforo de peatones y enviara el mensaje correspondiente almacenado en la tarjeta de memoria de vuelta al telefono movil, el cual comunicara la informacion al usuario mediante la option seleccionada en la aplicacion. En cuanto el estado lumlnico del semaforo varle, se enviara inmediatamente un nuevo mensaje al telefono movil del usuario indicandole dicha variacion.If the user moves along the street and has activated in the mobile application the reception of information of the light status of the pedestrian traffic light, when approaching a crossing, the signal emitted by bluetooth technology by his mobile phone will be received by the module Bluetooth of the device located in the traffic light, then the device's microcontroller will process the signals of the pedestrian traffic light and send the corresponding message stored in the memory card back to the mobile phone, which will communicate the information to the user through the option selected in the application. As soon as the light status of the traffic light varies, a new message will be immediately sent to the user's mobile phone indicating that variation.
Si el usuario tiene seleccionada la option de recibir information de obras en la via publica y se aproxima a una valla de obra donde esta situado el dispositivo, de la misma forma que en el ejemplo anterior este emitira el mensaje correspondiente al telefono movil del usuario advirtiendole de la situation de riesgo. La unica diferencia en este caso es que el 5 microcontrolador del dispositivo no necesita procesar senales externas como en el semaforo, simplemente enviar el mensaje correspondiente a la solicitud recibida.If the user has selected the option to receive information of works on the public road and approaches a work fence where the device is located, in the same way as in the previous example this will emit the corresponding message to the user's mobile phone warning of the risk situation. The only difference in this case is that the device's microcontroller does not need to process external signals as in the traffic light, simply send the corresponding message to the request received.
