Description

Sistema y método para la detección automática de accidentes de vehículos DESCRIPCIÓN La presente invención hace referencia a un sistema y a un método para la detección automática de accidentes de vehículos tales como por ejemplo, un automóvil o una motocicleta, entre otros.  System and method for the automatic detection of vehicle accidents DESCRIPTION The present invention refers to a system and a method for the automatic detection of vehicle accidents such as, for example, a car or a motorcycle, among others.
En particular, la presente invención hace referencia a un sistema y a un método que permite detectar de manera automática accidentes de vehículos evitando al máximo las falsas alarmas. In particular, the present invention refers to a system and a method that allows automatic detection of vehicle accidents avoiding false alarms.
Como es bien conocido, los accidentes de tráfico suponen una de las primeras causas de muerte para la humanidad. Es por ello que se necesitan sistemas de detección de accidentes que permitan detectar en el mínimo tiempo posible el accidente producido y comunicar de manera automática a los servicios de emergencia el lugar geográfico donde se ha producido el accidente, independientemente de que el accidente haya sido al volante de un vehículo a motor, montando en bicicleta por la montaña, montado en motocicleta por una carretera secundaria, etc. As is well known, traffic accidents are one of the leading causes of death for humanity. That is why accident detection systems are needed that allow the accident to be detected in the minimum possible time and automatically communicate to the emergency services the geographical location where the accident occurred, regardless of whether the accident has been at steering wheel of a motor vehicle, riding a mountain bike, riding a motorcycle on a secondary road, etc.
Es bien sabido que la Unión Europea está invirtiendo en un proyecto llamado "HeERO 2" basado en el conocido proyecto y servicio de llamadas de emergencia a nivel europeo denominado "eCall" basado en el número 1 12 común en toda Europa para servicios de emergencia. El proyecto "eCall" consiste en que todos los coches puedan llevar insertado de fábrica un sistema de detección de accidentes. Se espera que a partir de 2018 la incorporación del sistema "eCall" sea obligatoria en todos los coches nuevos en Europa. No obstante, a partir de 2018, se estima que se necesitará un mínimo de 20 años para que el parque automovilístico se haya renovado completamente en Europa. Adicionalmente, tanto el proyecto HeERO 2 como el proyecto "eCall" únicamente están previstos en automóviles, no incluyendo su disposición en motocicletas, bicicletas ni en cualquier otro vehículo que no sea un automóvil. It is well known that the European Union is investing in a project called "HeERO 2" based on the well-known project and emergency call service at European level called "eCall" based on the number 1 12 common throughout Europe for emergency services. The "eCall" project is that all cars can have an accident detection system inserted at the factory. It is expected that from 2018 the incorporation of the "eCall" system will be mandatory in all new cars in Europe. However, as of 2018, it is estimated that a minimum of 20 years will be required for the car park to be completely renovated in Europe. Additionally, both the HeERO 2 project and the "eCall" project are only provided for cars, not including their provision on motorcycles, bicycles or any vehicle other than a car.
Son conocidos en el estado de la técnica procedimientos de detección de impactos mediante la utilización de un acelerómetro. Este último es un sensor que viene incorporado de serie en la gran mayoría de los dispositivos electrónicos móviles de tipo inteligente o comúnmente conocidos del inglés como "smartphones". Dicho acelerómetro en un teléfono inteligente es capaz de medir la aceleración, así como otras variables tales como por ejemplo, el ángulo de inclinación, la rotación, la vibración, el choque y la gravedad del teléfono inteligente. Así pues, existen procedimientos de detección de impactos que se basan en medir la fuerza de aceleración que genera el teléfono inteligente tras por ejemplo, un impacto como puede ser un accidente y automáticamente el teléfono inteligente realiza una llamada automática al centro de emergencias. Sin embargo, este tipo de procedimientos técnicos genera un problema sustancial y muy peligroso: la gran mayoría de impactos que recibe el teléfono inteligente no son necesariamente accidentes que sufre el usuario de dicho teléfono móvil, sino impactos fortuitos del propio teléfono inteligente (por ejemplo, una caída del teléfono al suelo, o que el usuario esté realizando motocross o trial con el teléfono móvil encima, etc.). Del mismo modo, cuando un vehículo dispone de un dispositivo integrado en el mismo que permite medir las aceleraciones y se utilizan procedimientos de detección de accidentes únicamente midiendo los cambios de aceleración que sufre dicho acelerómetro integrado en dicho vehículo, pueden sucederse situaciones de falsa alarma como por ejemplo que se caiga la moto aparcada. Si los citados sistemas y procedimientos o similares fuesen establecidos de forma masiva o bien en todos los teléfonos inteligentes, o bien en todos los vehículos o accesorios de vehículos (navegadores, etc.), la gran cantidad de falsos positivos o llamadas por error podrían saturar los recursos de los centros de emergencias, impidiendo atender los verdaderos accidentes. Es pues un objetivo de la presente invención conseguir un sistema y un método de detección automática de accidentes que sea capaz de diferenciar un simple impacto de un teléfono móvil de un accidente real en un vehículo y luego sea capaz de transmitir la información para que se pueda gestionar la emergencia. Asimismo, es un objetivo de la presente invención dar a conocer un sistema y un método de detección automática de accidentes que permita ser utilizado en cualquier tipo de vehículo existente de una manera eficaz y eficiente. Methods of detecting impacts by using an accelerometer are known in the state of the art. The latter is a sensor that comes incorporated as standard in the vast majority of mobile electronic devices of intelligent type or commonly known in English as "smartphones". Said accelerometer in a smartphone is capable of measuring acceleration, as well as other variables such as, for example, the angle of inclination, rotation, vibration, shock and gravity of the smartphone. Thus, there are impact detection procedures that are based on measuring the acceleration force generated by the smartphone after, for example, an impact such as an accident and the smartphone automatically makes an automatic call to the emergency center. However, this type of technical procedures generates a substantial and very dangerous problem: the vast majority of impacts that the smartphone receives are not necessarily accidents suffered by the user of said mobile phone, but rather accidental impacts of the smartphone itself (for example, a fall of the phone to the ground, or that the user is performing motocross or trial with the mobile phone on top, etc.). In the same way, when a vehicle has an integrated device that allows acceleration to be measured and accident detection procedures are used only by measuring the acceleration changes suffered by said accelerometer integrated in said vehicle, false alarm situations can occur such as for example that the parked motorcycle falls. If the aforementioned systems and procedures or the like were established massively or in all smartphones, or in all vehicles or vehicle accessories (browsers, etc.), the large number of false positives or error calls could saturate the resources of the emergency centers, preventing to attend the true accidents. It is therefore an objective of the present invention to achieve a system and an automatic accident detection method that is able to differentiate a simple impact of a mobile phone from a real accident in a vehicle and then be able to transmit the information so that it can Manage the emergency It is also an objective of the present invention to provide a system and an automatic accident detection method that allows it to be used in any type of existing vehicle in an effective and efficient manner.
Según la presente invención, esto se consigue mediante un sistema para la detección automática de accidentes de vehículos que comprende al menos un primer dispositivo electrónico asociado a un usuario, tal como por ejemplo un teléfono móvil inteligente. Dicho primer dispositivo electrónico comprende adicionalmente: al menos un módulo de comunicación de voz y datos por al menos un tipo de red inalámbrica; al menos un módulo de localización de posición geográfica y al menos un acelerómetro. Dicho sistema se caracteriza porque comprende adicionalmente al menos un segundo dispositivo electrónico asociado a al menos un vehículo de dicho usuario adaptado para enlazarse con al menos dicho primer dispositivo electrónico. Preferentemente, el enlace entre dicho primer y segundo dispositivo electrónico se hace mediante una conexión inalámbrica de área personal, tal como por ejemplo, Bluetooth. Opcionalmente, el enlace entre dicho primer y segundo dispositivo electrónico puede realizarse mediante una conexión física, tal como por ejemplo, una conexión por cable. Adicionalmente, el sistema se caracteriza porque comprende al menos un servidor de datos adaptado para recibir y procesar al menos datos de localización geográfica y de aceleración de dicho primer dispositivo electrónico cuando éste se encuentra enlazado con dicho segundo dispositivo electrónico. De este modo, cuando el acelerómetro del primer dispositivo electrónico ya enlazado con el segundo dispositivo electrónico (esto es, el usuario se encuentra en disposición de conducir o conduciendo ya el vehículo), sufre un cambio en la fuerza de aceleración, el sistema se activa en una primera instancia por un supuesto accidente, descartando un porcentaje alto de falsas alarmas por caída espontánea del móvil al suelo sin estar el usuario conduciendo ningún vehículo. According to the present invention, this is achieved by a system for the automatic detection of vehicle accidents comprising at least a first electronic device associated with a user, such as for example a mobile smart phone. Said first electronic device further comprises: at least one voice and data communication module for at least one type of wireless network; at least one location module for geographic position and at least one accelerometer.

Additionally, the system is characterized in that it comprises at least one data server adapted to receive and process at least geographic location and acceleration data of said first electronic device when it is linked to said second electronic device. Thus, when the accelerometer of the first electronic device already linked to the second electronic device (that is, the user is ready to drive or already driving the vehicle), undergoes a change in the acceleration force, the system is activated in the first instance due to an alleged accident, discarding a high percentage of false alarms due to spontaneous fall of the mobile to the ground without the user driving any vehicle.
Opcionalmente, dicho primer dispositivo electrónico comprende adicionalmente un giroscopio cuyos datos se envían y analizan por dicho servidor de datos. Optionally, said first electronic device further comprises a gyroscope whose data is sent and analyzed by said data server.
Opcionalmente, dicho segundo dispositivo electrónico comprende adicionalmente un acelerómetro cuyos datos se envían y se analizan conjuntamente con los datos del acelerómetro de dicho primer dispositivo electrónico por dicho servidor de datos. Preferentemente, dicho primer dispositivo electrónico es un teléfono móvil inteligente que comprende una aplicación que se comunica con dicho segundo dispositivo electrónico y es capaz de enviar datos de diferentes tipos medidos por dicho primer dispositivo electrónico al servidor de datos. Preferentemente, dicho vehículo puede ser un automóvil, una motocicleta o una bicicleta, entre otros. Optionally, said second electronic device further comprises an accelerometer whose data is sent and analyzed in conjunction with the accelerometer data of said first electronic device by said data server. Preferably, said first electronic device is a mobile smart phone comprising an application that communicates with said second electronic device and is capable of sending data of different types measured by said first electronic device to the data server. Preferably, said vehicle can be a car, a motorcycle or a bicycle, among others.
Según la presente invención, dicho sistema puede implementar un método de detección de accidentes que se caracteriza porque comprende las siguientes etapas: According to the present invention, said system can implement an accident detection method characterized in that it comprises the following steps:
- una etapa inicial en la que dicho primer dispositivo electrónico se enlaza con dicho segundo dispositivo electrónico;  - an initial stage in which said first electronic device is linked to said second electronic device;

¡i. dicho servidor de datos capta y analiza durante un intervalo de tiempo predeterminado si se producen cambios en al menos los datos de localización geográfica y los datos de dicha fuerza de aceleración del primer dispositivo electrónico;  I. said data server captures and analyzes for a predetermined time interval if changes occur in at least the geographic location data and the data of said acceleration force of the first electronic device;
Ni. en caso de no haber cambios en dichos datos de localización geográfica y en dichos datos de fuerza de aceleración durante dicho intervalo de tiempo, dicho servidor de datos notifica a al menos un equipo de emergencia enviando al menos datos personales y/o médicos del usuario de dicho primer dispositivo electrónico.  Neither. in case there are no changes in said geographic location data and in said acceleration force data during said time interval, said data server notifies at least one emergency team sending at least personal and / or medical data of the user of said first electronic device.
Preferentemente, dicho cambio en la fuerza de aceleración del primer dispositivo electrónico tiene que ser mayor o igual a 3,5g (siendo "g" la aceleración de la gravedad en la superficie de la tierra) para que el sistema de detección de accidentes se active.

Asimismo, dicho primer dispositivo electrónico -1 1- es capaz de comunicarse con un servidor remoto de datos -14- y enviarle a través de dicha aplicación todos los datos anteriormente citados. Adicionalmente, el usuario del primer dispositivo electrónico -1 1- puede configurar a través de dicha aplicación sus datos personales, así como sus datos médicos y otros tipos de datos como por ejemplo, las características del vehículo y matricula que suele utilizar. Said first electronic device -1 1- has an application that allows obtaining and processing the different data of the different internal components (GPS, Bluetooth, accelerometer, gyroscope, etc.) that allows measuring the first electronic device itself -1 1-. Likewise, said first electronic device -1 1- is able to communicate with a remote data server -14- and send it through said application all the aforementioned data. Additionally, the user of the first electronic device -1 1- can configure through said application their personal data, as well as your medical data and other types of data such as the characteristics of the vehicle and license plate that you usually use.
Según se puede apreciar en la figura 1 , el sistema -1- también comprende un segundo dispositivo electrónico -12- que se asocia con al menos un vehículo -13- susceptible de ser utilizado por el mismo usuario propietario del primer dispositivo electrónico -1 1-. Dicho segundo dispositivo electrónico -12- puede comprender un módulo de tipo Bluetooth del mismo tipo que el citado anteriormente para el primer dispositivo electrónico -11-. Alternativamente, dicho segundo dispositivo electrónico -12- también puede ser un conector del propio vehículo -13-, tal como por ejemplo, un cable auxiliar a un sistema de entretenimiento para vehículos del tipo "CarPlay" de Apple® o "Android Auto" de Google®, entre otros. As can be seen in Figure 1, the system -1- also comprises a second electronic device -12- that is associated with at least one vehicle -13- capable of being used by the same user who owns the first electronic device -1 1 -. Said second electronic device -12- can comprise a Bluetooth type module of the same type as the one mentioned above for the first electronic device -11-.

Por último, según se puede apreciar en la figura 1 , el sistema -1- comprende al menos un servidor remoto de datos -14- adaptado para recibir y procesar diferentes tipos de datos, tales como por ejemplo, datos de localización geográfica y de aceleración medidos por dicho primer dispositivo electrónico -1 1- y/o por dicho segundo -12- dispositivo electrónico a través de la aplicación anteriormente mencionada. Dicho servidor de datos -14- es el encargado de analizar los datos recibidos y verificar mediante sus procedimientos técnicos cuando se trata de un accidente o de un impacto fortuito. Adicionalmente, dicho servidor de datos -14- es capaz de comunicarse con al menos un centro de emergencias -15- para alertar de un posible accidente transmitiendo toda la información relevante medida por el primer -1 1- y/o segundo -12- dispositivo electrónico en relación con el supuesto accidente y enviando un servicio de emergencias (por ejemplo, una ambulancia -16-) a la posición geográfica del accidente. Además, el servidor de datos -14- es capaz de comunicarse con los diferentes centros de emergencias a escala global a través de diferentes redes de voz y datos. El servidor de datos -14- es el elemento que gestiona y almacena toda la actividad del sistema -1-. La figura 2 muestra un diagrama de flujos con las etapas de un método -2- de detección automática de accidentes según una primera realización de la presente invención. En una primera etapa inicial -21-, es necesario que el primer dispositivo electrónico -11- se enlace con el segundo dispositivo electrónico -12-. Para ello, tal y como se ha mencionado anteriormente dicho enlace puede realizarse de manera inalámbrica. Un ejemplo de realización de un enlace por medios inalámbricos puede consistir, por ejemplo, en que el segundo dispositivo electrónico -12-, una vez encendido, envía un identificador o una notificación de tipo "push", mediante por ejemplo la tecnología "Bluetooth Low Energy", dentro de un rango de cobertura de corto alcance de modo que cuando el primer dispositivo electrónico -1 1- entra dentro de dicho rango de alcance recibe dicha notificación "push" y activa automáticamente la aplicación de dicho primer dispositivo electrónico -1 1- y posteriormente realiza un vínculo con dicho segundo dispositivo electrónico -12-. Dicho enlace permite asegurar al sistema -1- que el usuario se encuentra en disposición de conducir o conduciendo ya el vehículo -13-. Finally, as can be seen in Figure 1, the system -1- comprises at least one remote data server -14- adapted to receive and process different types of data, such as, for example, geographic location and acceleration data measured by said first electronic device -1 1- and / or by said second -12- electronic device through the aforementioned application. Said data server -14- is responsible for analyzing the data received and verifying through its technical procedures when it is an accident or a fortuitous impact. Additionally, said data server -14- is able to communicate with at least one emergency center -15- to alert of a possible accident by transmitting all the relevant information measured by the first -1 1- and / or second -12- device electronic in relation to the alleged accident and sending an emergency service (for example, an ambulance -16-) to the geographical position of the accident. In addition, the data server -14- is able to communicate with the different emergency centers on a global scale through different voice and data networks. The data server -14- is the element that manages and stores all system activity -1-. Figure 2 shows a flow chart with the steps of a -2- method of automatic accident detection according to a first embodiment of the present invention. In a first initial stage -21-, it is necessary that the first electronic device -11- be linked to the second electronic device -12-. To do this, as mentioned above, this link can be made wirelessly. An example of making a link by wireless means may be, for example, that the second electronic device -12-, once switched on, sends an identifier or a "push" type notification, for example by "Bluetooth Low" technology Energy ", within a range of short-range coverage so that when the first electronic device -1 1- enters within said range it receives said" push "notification and automatically activates the application of said first electronic device -1 1 - and subsequently make a link with said second electronic device -12-. Said link allows to assure the system -1- that the user is ready to drive or already driving the vehicle -13-.
En caso de que el enlace entre el primer -11- y segundo -12- dispositivo electrónico se lleve a cabo, se procede con la etapa -22- donde el sistema -1- queda en espera para ver si se produce un cambio de aceleración en el acelerómetro de dicho primer -1 1- dispositivo electrónico. Cuando dicho primer dispositivo electrónico -11- detecta, mediante el acelerómetro, un cambio en la fuerza de aceleración cercana a 4g (tal como por ejemplo 3,5g), la aplicación de dicho primer dispositivo electrónico -11- recoge, como mínimo, los datos de dicha fuerza de aceleración y los datos de la localización geográfica de dicho primer dispositivo electrónico -1 1- en el momento de dicho cambio en la fuerza de aceleración y los reenvía al servidor de datos -14- (etapa -23-). Adicionalmente, la aplicación de dicho primer dispositivo electrónico -1 1- puede recoger y enviar al servidor de datos -14- datos del giroscopio (en el caso de que dicho primer dispositivo electrónico -1 1- disponga del mismo) y de otros sensores adicionales que pueda incorporar dicho primer dispositivo electrónico -1 1-. En la siguiente etapa -24-, el servidor de datos -14- procede a captar y analizar durante un intervalo de tiempo predeterminado, por ejemplo, menor o igual a 20 segundos, si se producen cambios en, al menos, los datos de localización geográfica y los datos de dicha fuerza de aceleración del primer dispositivo electrónico -1 1-. Adicionalmente, el servidor de datos -14- también puede captar y analizar otras variables susceptibles de ser medidas por el primer dispositivo electrónico -11-, tal como por ejemplo, cambios de movimiento o de sentido a través del giroscopio, análisis del ritmo cardiaco de la persona en el caso de que dicho primer dispositivo electrónico -11- consista en un reloj o pulsera inteligencia y sea susceptible de medir el pulso del usuario o comprenda un medidor de constantes vitales. Cuantas más variables se puedan llegar a medir, ello permitirá reducir un porcentaje relevante de falsos positivos. In case the link between the first -11- and second -12- electronic device is carried out, proceed with step -22- where the system -1- is waiting to see if an acceleration change occurs in the accelerometer of said first -1 1- electronic device. When said first electronic device -11- detects, by means of the accelerometer, a change in the acceleration force close to 4g (such as 3.5g), the application of said first electronic device -11- collects at least the data of said acceleration force and geographic location data of said first electronic device -1 1- at the time of said change in acceleration force and forwards them to the data server -14- (step -23-). Additionally, the application of said first electronic device -1 1- can collect and send data from the gyroscope to the data server -14- (in case said first electronic device -1 1- has the same) and other additional sensors which may incorporate said first electronic device -1 1-. In the next step -24-, the data server -14- proceeds to capture and analyze for a predetermined time interval, for example, less than or equal to 20 seconds, if changes occur in at least the location data geographic and the data of said acceleration force of the first electronic device -1 1-. Additionally, the data server -14- can also capture and analyze other variables that can be measured by the first electronic device -11-, such as for example, changes of movement or direction through the gyroscope, analysis of the person's heart rhythm in the event that said first electronic device -11- consists of an intelligence watch or bracelet and is capable of measuring the user's pulse or understand a vital signs meter. The more variables that can be measured, this will reduce a relevant percentage of false positives.
Durante dicho análisis por parte del servidor de datos -14- en la etapa -24-, opcionalmente se puede proceder (-242-) a realizar una llamada al usuario propietario de dicho primer dispositivo electrónico -11- (etapa -244-). En el caso de que el usuario no responda o no haya cobertura (-243-) se podrá tener en cuenta por parte del servidor de datos -14- para decidir si conjuntamente con otras variables medidas se puede tratar de un accidente o no. En caso (-241 -) de que, transcurridos los 20 segundos de análisis por parte del servidor de datos -14-, coincida que no se han detectado cambios en los datos de localización geográfica ni en los datos de fuerza de aceleración medidos por el primer dispositivo electrónico -11-, dicho servidor de datos -14- procede a notificar (etapa -25- ) a al menos un centro de emergencias -15- que esté dispuesto lo más cercano a la posición geográfica del supuesto accidente para alertar del mismo, enviando los datos personales y/o médicos del usuario de dicho primer -1 1- y segundo -12- dispositivos electrónicos, así como otros datos de interés como por ejemplo, las características del vehículo y matricula del vehículo que comprende dicho segundo dispositivo electrónico -12-. During said analysis by the data server -14- in step -24-, optionally (-242-) it is possible to make a call to the user who owns said first electronic device -11- (step -244-). In the event that the user does not respond or there is no coverage (-243-) it may be taken into account by the data server -14- to decide if together with other measured variables it can be an accident or not. In case (-241 -) that, after 20 seconds of analysis by the data server -14-, it is agreed that no changes have been detected in the geographic location data or in the acceleration force data measured by the first electronic device -11-, said data server -14- proceeds to notify (step -25-) to at least one emergency center -15- that is arranged as close to the geographical position of the alleged accident to alert it , sending the personal and / or medical data of the user of said first -1 1- and second -12- electronic devices, as well as other data of interest such as, for example, the characteristics of the vehicle and vehicle registration comprising said second electronic device -12-.
En caso contrario (-245-), el sistema -1- descarta un supuesto accidente y vuelve a la etapa -22- quedando a la espera de un cambio significativo en la fuerza de aceleración del acelerómetro de dicho primer dispositivo electrónico -1 1-. La figura 3 muestra un diagrama de flujos con las etapas de un método -3- de detección automática de accidentes según una segunda realización de la presente invención. En una primera etapa inicial -31- es necesario que el primer dispositivo electrónico -11- se enlace de un modo similar con el segundo dispositivo electrónico - 12- tal y como se ha explicado anteriormente en relación con la primera realización (figura 2). Del mismo modo, dicho enlace permite asegurar al sistema -1- que el usuario se encuentra en disposición de conducir o conduciendo ya el vehículo -13-. Otherwise (-245-), the system -1- discards an alleged accident and returns to stage -22- while waiting for a significant change in the acceleration force of the accelerometer of said first electronic device -1 1- . Figure 3 shows a flow chart with the steps of a method -3- of automatic accident detection according to a second embodiment of the present invention. In a first initial stage -31- it is necessary that the first electronic device -11- be linked in a similar way with the second electronic device -12- as explained above in relation to the first embodiment (Figure 2). In the same way, this link allows to ensure the system -1- that the The user is ready to drive or already driving the vehicle -13-.
En caso de que el enlace entre el primer -11- y segundo -12- dispositivo electrónico se lleve a cabo, se procede con la etapa -32- donde el sistema -1- queda en espera para ver si se produce un cambio de aceleración en el acelerometro de dicho primer -11- y segundo -12- dispositivo electrónico. A diferencia de la primera realización (figura 2), en este caso dicho segundo -12- dispositivo electrónico tiene que comprender también un acelerometro. Cuando dichos primer -1 1- y segundo -12- dispositivos electrónicos detectan, mediante sus respectivos aceleró metros, al menos un cambio en la fuerza de aceleración, por ejemplo, una fuerza cercana a 4g (por ejemplo 3,5g), se envían al servidor de datos -14-, como mínimo, los datos de dicha fuerza de aceleración tanto del primer -1 1- como del segundo -12- dispositivo electrónico, así como los datos de la localización geográfica de dicho primer dispositivo electrónico -1 1- en el momento de dichos cambios en la fuerza de aceleración (etapa -33-). Adicionalmente, se pueden enviar al servidor de datos -14- datos del giroscopio (en el caso de que tanto dicho primer -1 1- como segundo -12- dispositivo electrónico dispongan del mismo) y de otros sensores adicionales que puedan incorporar los mismos dispositivos -1 1- y -12-. En este caso, el sistema -1- lleva a cabo un doble control de posibles impactos para obtener una doble verificación de un supuesto accidente del usuario. In case the link between the first -11- and second -12- electronic device is carried out, proceed with step -32- where the system -1- is waiting to see if there is an acceleration change in the accelerometer of said first -11- and second -12- electronic device. Unlike the first embodiment (Figure 2), in this case said second electronic device must also comprise an accelerometer. When said first -1 1- and second -12- electronic devices detect, by their respective accelerated meters, at least one change in the acceleration force, for example, a force close to 4g (for example 3.5g), they are sent to the data server -14-, at a minimum, the data of said acceleration force of both the first -1 1- and the second -12- electronic device, as well as the geographic location data of said first electronic device -1 1 - at the time of said changes in the acceleration force (step -33-). Additionally, gyroscope data -14- can be sent to the data server -14- in the case that both said first -1 1- and second -12- electronic device have the same) and other additional sensors that can incorporate the same devices -1 1- and -12-. In this case, the system -1- carries out a double control of possible impacts to obtain a double verification of a supposed user accident.
En caso de que únicamente uno de los dos dispositivos (-1 1- y -12-) tengan un cambio significante en la fuerza de aceleración, el sistema -1- no interpreta dicho cambio como posible accidente y se mantiene a la espera en la etapa -32-. Posteriormente, en la siguiente etapa -34-, el servidor de datos -14- procede a captar y analizar durante un intervalo de tiempo predeterminado, por ejemplo, menor o igual a 20 segundos, si se producen cambios en, al menos, los datos de localización geográfica y los datos de dicha fuerza de aceleración del primer -11- y segundo -12- dispositivo electrónico. Adicionalmente, el servidor de datos -14- también puede captar y analizar otras variables susceptibles de ser medidas por el primer -11- y segundo - 12- dispositivo electrónico, tal como por ejemplo, cambios de movimiento o de sentido a través del giroscopio. Adicionalmente, el servidor de datos -14- también puede captar y analizar otras variables susceptibles de ser medidas únicamente por el primer -1 1- dispositivo electrónico, tal como por ejemplo, ritmo cardiaco de la persona en el caso de que dicho primer dispositivo electrónico -1 1- consista en un reloj o pulsera inteligencia y sea susceptible de medir el pulso del usuario o comprenda un medidor de constantes vitales. In the event that only one of the two devices (-1 1- and -12-) have a significant change in the acceleration force, the system -1- does not interpret this change as a possible accident and is kept waiting in the stage -32-. Subsequently, in the next step -34-, the data server -14- proceeds to capture and analyze for a predetermined time interval, for example, less than or equal to 20 seconds, if changes occur in at least the data of geographic location and the data of said acceleration force of the first -11- and second -12- electronic device. Additionally, the data server -14- can also capture and analyze other variables that can be measured by the first -11- and second -12- electronic device, such as, for example, changes in movement or direction through the gyroscope. Additionally, the data server -14- can also capture and analyze other variables that can only be measured by the first -1 1- electronic device, such as, for example, the person's heart rate in the event that said first electronic device -1 1- consists of a watch or bracelet intelligence and be able to measure the user's pulse or understand a vital signs meter.
Durante dicho análisis por parte del servidor de datos -14- en la etapa -34-, opcionalmente se puede proceder (-342-) a realizar una llamada al usuario propietario de dicho primer dispositivo electrónico -11- (etapa -344-). En el caso de que el usuario no responda o no haya cobertura (-343-), este hecho se podrá tener en cuenta por parte del servidor de datos -14- para decidir si conjuntamente con otras variables medidas se puede tratar de un supuesto accidente o no. During said analysis by the data server -14- in step -34-, optionally (-342-) it is possible to make a call to the user who owns said first electronic device -11- (step -344-). In the event that the user does not respond or there is no coverage (-343-), this fact can be taken into account by the data server -14- to decide if together with other measured variables it can be an alleged accident or not.
En caso (-341 -) de que, transcurridos los 20 segundos de análisis por parte del servidor de datos -14-, coincida que no se han detectado cambios en los datos de localización geográfica ni en los datos de fuerza de aceleración medidos por el primer -1 1- y segundo -12- dispositivo electrónico, dicho servidor de datos -14- procede a notificar (etapa -35-) a al menos un centro de emergencias -15- que esté dispuesto lo más cercano a la posición geográfica del supuesto accidente para alertar del mismo, enviando los datos personales y/o médicos del usuario de dicho primer -1 1- y segundo -12- dispositivo electrónico, así como otros datos de interés como por ejemplo, las características del vehículo y matricula del vehículo que comprende dicho segundo dispositivo electrónico -12-. In case (-341 -) that, after 20 seconds of analysis by the data server -14-, it is agreed that no changes have been detected in the geographic location data or in the acceleration force data measured by the first -1 1- and second -12- electronic device, said data server -14- proceeds to notify (step -35-) to at least one emergency center -15- that is arranged as close to the geographical position of the alleged accident to warn of it, sending the personal and / or medical data of the user of said first -1 1- and second -12- electronic device, as well as other data of interest such as, for example, the characteristics of the vehicle and vehicle registration comprising said second electronic device -12-.
En caso contrario (-345-), el sistema -1- descarta un supuesto accidente y vuelve a la etapa -32- quedando a la espera de un cambio significativo en la fuerza de aceleración tanto del acelerómetro de dicho primer dispositivo electrónico -1 1- como del segundo - 12- dispositivo electrónico. Otherwise (-345-), the system -1- discards an alleged accident and returns to step -32- while waiting for a significant change in the acceleration force of both the accelerometer of said first electronic device -1 1 - as of the second - 12- electronic device.
Opcionalmente, tanto en la primera como en la segunda realización (figuras 2 y 3 respectivamente), una vez el servidor de datos -14- detecta un supuesto accidente a la vista de las variables medidas, el sistema -1- puede comprender un centro de gestión (no ilustrado), donde recibe la notificación emitida por dicho servidor de datos -14- de manera que una persona de dicho centro de gestión pueda, o bien realizar una llamada por VolP (Voz sobre IP) con el primer dispositivo electrónico -11- del usuario, activando automáticamente el altavoz y micrófono de dicho primer dispositivo electrónico -1 1-, o bien activando el propio teléfono para que éste realice una llamada por VolP con dicho centro de gestión permitiendo comunicarse mediante voz con el usuario de dicho primer dispositivo electrónico -11- y adicionalmente con las personas que pudieran estar eventualmente en el interior del vehículo. Esto permite que el sistema -1- pueda asistir y gestionar la emergencia estando en todo momento en contacto con el usuario propietario del primer dispositivo electrónico -1 1- y resto de personas que acompañan a dicho usuario en el interior del vehículo -13-. Optionally, both in the first and in the second embodiment (Figures 2 and 3 respectively), once the data server -14- detects an alleged accident in view of the measured variables, the system -1- can comprise a center of management (not illustrated), where it receives the notification issued by said data server -14- so that a person from said management center can either make a call by VolP (Voice over IP) with the first electronic device -11 - of the user, automatically activating the loudspeaker and microphone of said first electronic device -1 1-, or activating the phone itself so that it makes a call by VolP with said management center allowing voice communication with the user of said first electronic device -11- and additionally with people who could possibly be inside the vehicle. This allows that the system -1- can assist and manage the emergency being at all times in contact with the owner of the first electronic device -1 1- and other people accompanying said user inside the vehicle -13-.
Finalmente, el sistema -1- y método según la presente invención reduce los falsos positivos y aumenta la eficiencia y eficacia del sistema -1- para la gestión remota de los accidentes en la conducción. Finally, the system -1- and method according to the present invention reduces false positives and increases the efficiency and effectiveness of the system -1- for the remote management of driving accidents.
