DESCRIPCIÓNDESCRIPTION

DISPOSITIVO DE AVISO DE CAÍDAS A DISTINTO NIVEL DE TIPO EXTENSÓMETROEXTENSOMETER TYPE FALL WARNING DEVICE AT DIFFERENT LEVELS

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION

La presente invención trata de un dispositivo de aviso de caídas a distinto nivel de tipo extensómetro destinado a unirse a una cinta que se une a un punto de anclaje y a un arnés de un usuario, dotada de un elemento conductor destinado a vincularse o integrarse en la cinta, donde en una situación de caída la cinta se tensa, variando el valor del potencial eléctrico del elemento conductor entre dos puntos y se emite una alarma.The present invention deals with a device for warning falls at different levels of the extensometer type intended to be attached to a strap that is attached to an anchor point and to a user's harness, provided with a conductive element intended to be linked or integrated into the tape, where in a fall situation the tape is tightened, varying the value of the electrical potential of the conductive element between two points and an alarm is emitted.

Concretamente la presente invención permite enviar un aviso justo en el momento que se ha producido la caída de modo que se reduce al mínimo la alerta a los servicios de rescate y emergencia, reduciendo el riesgo de que el operario pueda padecer un shock ortostático. Adicionalmente el dispositivo es acoplable a cualquier cinta existente en el mercado y ocupa poco volumen.Specifically, the present invention allows a warning to be sent just at the moment that the fall has occurred, so that the alert to the rescue and emergency services is reduced to a minimum, reducing the risk that the operator may suffer an orthostatic shock. Additionally, the device can be attached to any existing tape on the market and occupies little volume.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Actualmente son conocidos sistemas de sujeción que permiten asegurar al trabajador mediante arneses y cintas cuando está realizando trabajos a distinto nivel, de modo que si un operario sufre una caída este queda suspendido y no cae al suelo. En el caso de quedar suspendido y en estado de inconsciencia, el operario debe ser rescatado lo antes posible, puesto que en caso contrario corre el peligro de entrar en shock ortostático en cuestión de minutos. Son conocidos en el estado de la técnica dispositivos que amortiguan la presión del arnés en el individuo o que absorben la energía generada durante la caídaAt present, fastening systems are known that allow the worker to be secured by means of harnesses and straps when he is carrying out work at different levels, so that if an operator suffers a fall, he remains suspended and does not fall to the ground. In the case of being suspended and in a state of unconsciousness, the operator must be rescued as soon as possible, since otherwise he runs the risk of going into orthostatic shock in a matter of minutes. Devices that cushion the pressure of the harness on the individual or that absorb the energy generated during the fall are known in the state of the art.

Sin embargo, estos dispositivos se limitan a sujetar y evitar la caída del operario, y no reducen el riesgo de que el operario sufra un posible shock ortostático.However, these devices are limited to supporting and preventing the operator from falling, and do not reduce the risk of the operator suffering from possible orthostatic shock.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

El dispositivo de aviso de caídas de trabajos a distinto nivel de tipo extensómetro, está destinado a unirse a una cinta que está de un primer extremo destinado a unirse a un punto de anclaje y un segundo extremo destinado a unirse al arnés del usuario. El dispositivo comprende una carcasa que define una cavidad y que está destinada a vincularse a la cinta, un elemento conductor longitudinal limitado por un primer extremo y un segundo extremo, en el que el elemento conductor está destinado a integrarse o a vincularse a la cinta, al menos una batería de alimentación alojada en la carcasa y un microcontrolador alojado en la cavidad y alimentado por la batería.The extensometer-type work fall warning device at different levels is intended to be attached to a tape that is at a first end intended to be attached to a point anchorage and a second end intended to be attached to the user's harness. The device comprises a casing defining a cavity and intended to be attached to the tape, a longitudinal conductive element limited by a first end and a second end, in which the conductive element is intended to be integrated or attached to the tape, minus a power supply battery housed in the casing and a microcontroller housed in the cavity and powered by the battery.

El microcontrolador está dotado de un conector de red inalámbrica destinado a conectarse a una centralita, un pin de salida conectado al primer extremo del elemento conductor y un pin de entrada conectado al segundo extremo. El microcontrolador recibe y evalúa la diferencia del potencial eléctrico entre el primer extremo y el segundo extremo y en una situación de caída en el que la cinta se tensa, detecta una diferencia de tensión y envía una señal de alarma a la centralita y/o a un dispositivo móvil a través del conector de red inalámbrica.The microcontroller is provided with a wireless network connector intended to be connected to a switchboard, an output pin connected to the first end of the conductive element and an input pin connected to the second end. The microcontroller receives and evaluates the difference in electrical potential between the first end and the second end and in a fall situation in which the belt is tightened, it detects a difference in tension and sends an alarm signal to the control unit and/or to a mobile device through the wireless network connector.

De esta manera, en el mismo momento en el que se produce la caída, se envía una señal de alarma, reduciendo el tiempo de actuación. El elemento conductor tiene propiedades eléctricas conductoras de manera que los valores del potencial eléctrico varían en función de la tensión que soporta.In this way, at the very moment in which the fall occurs, an alarm signal is sent, reducing the action time. The conductive element has conductive electrical properties such that the values of the electrical potential vary as a function of the voltage it supports.

El elemento conductor puede ser un hilo de óxido de nitrón, donde el hilo puede estar o bien vinculado al exterior de la cinta o bien integrado en esta. Alternativamente el elemento conductor puede ser una pintura con propiedades conductoras.The conductive element may be a nitron oxide thread, where the thread may be either attached to the outside of the tape or integrated into it. Alternatively, the conductive element can be a paint with conductive properties.

El dispositivo puede comprender un emisor acústico y/o luminoso vinculado al microcontrolador que es activado por el microcontrolador en una situación de caída, de manera que se alerta a cualquier persona que esté cerca de que se ha producido un accidente.The device may comprise an acoustic and/or light emitter linked to the microcontroller that is activated by the microcontroller in a fall situation, so that anyone nearby is alerted that an accident has occurred.

El microcontrolador recibe los datos y los procesa evaluando si se ha producido o no una incidencia. Cuando éste mediante la lógica que posee en su interior detecta una incidencia, envía la información a través del conector de red y el protocolo por el que se le haya configurado. Ésta electrónica puede trabajar tanto con redes LoRaWAN, Bluetooth 5, WiFi, Sigfox, NBIoT, 5G y 4G de manera indistinta en función de las conexiones que se seleccionen en su placa, de esta manera se puede implementar su uso sea cual sea la estructura de red disponible. The microcontroller receives the data and processes it, evaluating whether or not an incident has occurred. When this, through the logic it has inside, detects an incident, it sends the information through the network connector and the protocol by which it has been configured. This electronics can work with both LoRaWAN, Bluetooth 5, WiFi, Sigfox, NBIoT, 5G and 4G networks indistinctly depending on the connections selected on its board, in this way its use can be implemented whatever the structure of network available.
