SENSOR DE VELOCIDAD Y CADENCIA DE GIRO OBJETO DE LA INVENCIÓN SPEED SENSOR AND SPINNING CADENCE OBJECT OF THE INVENTION
La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un sensor de velocidad y cadencia de giro, el cual presenta una serie de ventajas y características de novedad, que se explicarán en detalle más adelante, que suponen una destacable mejora en el estado actual de la técnica. The invention, as expressed in the statement of the present specification, refers to a speed sensor and rotation rate, which presents a series of advantages and characteristics of novelty, which will be explained in detail later, which represent a remarkable improvement in the current state of the art.
El objeto de la presente invención se centra, concretamente, en un sensor que, siendo principalmente aplicable en ciclismo, permite medir la velocidad y cadencia de un elemento que gira en un eje a partir de la generación de la fuerza electromotriz inducida por la parte móvil que gira alrededor de dicho eje. The object of the present invention focuses, specifically, on a sensor that, being mainly applicable in cycling, allows to measure the speed and cadence of an element that rotates on an axis from the generation of the electromotive force induced by the moving part that revolves around said axis.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de dispositivos de medición, en particular sensores de velocidad y cadencia de giro. The field of application of the present invention is part of the industry sector dedicated to the manufacture of measuring devices, in particular speed and rotation rate sensors.
ANTECEDENTES DE LA INVENCIÓN Como referencia al estado actual de la técnica, los sensores para medir la velocidad y cadencia de giro de otro elemento que gira alrededor de un eje, requieren un parámetro externo de configuración para obtener el valor correcto, así como la existencia de una fuente de alimentación para la circuitería, por ejemplo una pila o batería. BACKGROUND OF THE INVENTION As a reference to the current state of the art, sensors to measure the speed and cadence of rotation of another element that rotates around an axis, require an external configuration parameter to obtain the correct value, as well as the existence of a power source for the circuitry, for example a battery or battery.
Así, los sensores convencionales para medir la velocidad de un ciclista, precisan de la colocación del sensor en la propia bicicleta, dado que las señales se generan en la propia bicicleta y, asimismo, se requiere el uso de mediciones en diferentes puntos para medir la velocidad de giro de la rueda de la bicicleta y de la biela del pedal. Es necesario colocar un punto de medición en la rueda para adquirir el valor de la velocidad, y otro punto de medición en la biela del pedal para adquirir el valor de cadencia de pedaleo. Thus, conventional sensors to measure the speed of a cyclist, require the placement of the sensor on the bike itself, since the signals are generated in the bicycle itself and, also, the use of measurements at different points is required to measure the turning speed of the bicycle wheel and the pedal rod. It is necessary to place a measuring point on the wheel to acquire the value of the speed, and another measurement point on the pedal rod to acquire the value of pedaling cadence.
Ello hace que, para obtener dichas mediciones se tenga que realizar una serie de actuaciones sobre cada bicicleta que se quiera utilizar sumando, además del coste del sensor o sensores con sus correspondientes componentes, electrónica y fuente de alimentación, el coste del trabajo de acople de los sensores a la rueda y a la biela del pedal de cada bicicleta. This means that, in order to obtain these measurements, a series of actions must be carried out on each bicycle that is to be used, adding, in addition to the cost of the sensor or sensors with their corresponding components, electronics and power supply, the cost of the coupling work of the sensors to the wheel and the pedal crank of each bicycle.
El objetivo de la presente invención es, por tanto, el desarrollo de un sensor de velocidad y candencia mucho más sencillo, que permita realizar la medición de dichos valores sin necesidad de una fuente de alimentación externa y, por ejemplo en el caso de la bicicleta, poder medir la velocidad de giro de la rueda a través de uno de los rodillos de una estructura de rodamiento fija, evitando la necesidad de incorporar el sensor en la propia bicicleta y de configurar ningún parámetro externo, por tanto, permitiendo dicha medición con cualquier bicicleta que se incorpore y se haga rodar sobre dicha estructura. The object of the present invention is, therefore, the development of a much simpler speed and refresh sensor, which makes it possible to measure said values without the need of an external power source and, for example in the case of the bicycle , to be able to measure the speed of rotation of the wheel through one of the rollers of a fixed bearing structure, avoiding the need to incorporate the sensor in the own bicycle and to configure any external parameter, therefore, allowing said measurement with any bicycle that is incorporated and rolled over said structure.
Por otra parte, y como referencia al estado actual de la técnica, hay que señalar que, al menos por parte del solicitante, se desconoce la existencia de ningún otro sensor de velocidad y cadencia que presente unas características técnicas, estructurales y constitutivas semejantes a las que presenta el que aquí se reivindica. On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of any other speed and cadence sensor that has technical, structural and constitutive characteristics similar to those of which presents the one claimed here.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
El sensor de velocidad y cadencia de giro que la invención propone, se configura, pues, como una destacable novedad dentro de su campo de aplicación, ya que a tenor de su implementación se alcanzan satisfactoriamente los objetivos anteriormente señalados, estando los detalles caracterizadores que lo distinguen, convenientemente recogidos en las reivindicaciones finales que acompañan a la presente memoria descriptiva. The sensor of speed and cadence of rotation that the invention proposes, is configured, then, as a remarkable novelty within its field of application, since according to its implementation the objectives previously indicated are satisfactorily achieved, the characteristic details being that distinguish, conveniently collected in the final claims that accompany the present specification.
De una manera concreta, lo que la invención propone, es un sensor que, principalmente aplicable en ciclismo, aunque no limitado exclusivamente a ello, permite medir la velocidad y cadencia de un elemento que gira en un eje a partir de la generación de la fuerza electromotriz inducida por la parte móvil que gira alrededor de dicho eje. In a concrete way, what the invention proposes, is a sensor that, mainly applicable in cycling, although not limited exclusively to it, allows to measure the speed and cadence of an element that rotates on an axis from the generation of force electromotive induced by the mobile part that rotates around said axis.
Para ello, el sensor en cuestión se configura a partir de un soporte al que se acoplan una serie de imanes, vinculados, a su vez, a una o varias bobinas conectadas a la electrónica que procesa la fuerza electromotriz generada para obtener los valores de velocidad y cadencia generados, estando este soporte destinado a fijarse solidariamente alrededor de la parte móvil giratoria del antedicho eje. De este modo, al girar dicha parte del eje, el soporte con los imanes gira alrededor del eje generando una variación de flujo magnético induciendo una fuerza electromagnética que se transmite a la bobina en forma de señal eléctrica utilizada por los componentes electrónicos que los transforman en señales digitales. Lógicamente, cuanto mayor es el número de imanes que incorpora el soporte, mayor es la resolución que se obtiene en la medición. For this, the sensor in question is configured from a support to which a series of magnets are attached, linked, in turn, to one or more coils connected to the electronics that process the generated electromotive force to obtain the velocity values and cadence generated, this support being intended to be fixed integrally around the rotating mobile part of the aforesaid axis. In this way, when rotating said part of the axis, the support with the magnets rotates around the axis generating a variation of magnetic flux inducing an electromagnetic force that is transmitted to the coil in the form of electrical signal used by the electronic components that transform them into digital signs. Logically, the greater the number of magnets that the support incorporates, the greater the resolution obtained in the measurement.
Así, en el caso de la aplicación del sensor sobre una estructura de rodillos para medir la velocidad y cadencia de pedaleo de un ciclista, la velocidad instantánea se obtiene a partir de la señal generada por el giro del rodillo al ser movido por la rueda de la bicicleta, y la adquisición de la cadencia se obtiene a partir de la fluctuación que la cadencia de pedaleo provoca en la generación eléctrica, debido a la gran resolución que permite la señal. Con ello, el sensor de la invención ofrece, frente a lo ya conocido en el mercado, las siguientes ventajas e innovaciones: Thus, in the case of the application of the sensor on a roller structure to measure the speed and cadence of a cyclist, the instantaneous speed is obtained from the signal generated by the rotation of the roller when moved by the wheel of a cyclist. the bicycle, and the acquisition of the cadence is obtained from the fluctuation that the pedaling cadence causes in the electric generation, due to the high resolution that the signal allows. With this, the sensor of the invention offers, against what is already known in the market, the following advantages and innovations:
- la propia energía electromotriz generada, conlleva la capacidad de adquirir los valores de velocidad y cadencia, - the generated electromotive energy itself, carries the capacity to acquire the values of speed and cadence,
- no es necesario una alimentación externa para la alimentación eléctrica de la circuitería, - no external power is necessary for the electrical supply of the circuitry,
- en el caso de las bicicletas, permite utilizar el rodillo de una estructura para colocar el sensor, en lugar de tener que incorporarlo directamente en la bicicleta, - sólo es necesario un punto de medición para conseguir la medida de la velocidad y la de cadencia de pedaleo, - permite incorporar más dispositivos y aumentar la capacidad de medición sensorial (temperatura, vibraciones,...) - in the case of bicycles, it allows to use the roller of a structure to place the sensor, instead of having to incorporate it directly on the bicycle, - only one measuring point is necessary to achieve the measurement of the speed and the pedaling cadence, - it allows to incorporate more devices and increase the capacity of sensory measurement (temperature, vibrations, ...)
- no es necesaria la manipulación de la bicicleta para conseguir la medición de la velocidad y la cadencia de pedaleo, - el propio sensor genera la energía necesaria para el funcionamiento de la electrónica,  - it is not necessary to manipulate the bicycle to achieve the measurement of the speed and the pedaling cadence, - the sensor itself generates the energy necessary for the operation of the electronics,
- no es necesaria la entrada de dos fuentes de señal independientes, - permite aumentar la resolución de las mediciones, - the input of two independent signal sources is not necessary, - it allows to increase the resolution of the measurements,
- el sensor puede ir incorporado en el buje de la rueda de la bicicleta, - the sensor can be incorporated in the wheel hub of the bicycle,
- la medición en el rodillo no requiere de configuración de la medida, y - the measurement on the roller does not require configuration of the measurement, and
- proporciona una mejor medioambiental, al no generar residuos por la no utilización de pilas o baterías de alimentación, - provides a better environmental, by not generating waste by not using batteries or power batteries,
El descrito sensor de velocidad y cadencia de giro consiste, pues, en una estructura innovadora de características desconocidas hasta ahora para el fin a que se destina, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita. The described sensor of speed and rotation rate consists, therefore, in an innovative structure of characteristics unknown until now for the purpose for which it is intended, reasons that together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that is requested.
DESCRIPCIÓN DE LOS DIBUJOS DESCRIPTION OF THE DRAWINGS
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características de la invención, se acompaña a la presente memoria descriptiva, como parte integrante de la misma, un plano en que con carácter ilustrativo y no limitativo se ha representado lo siguiente: To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part of the same, a plan in which the illustrative and non-limiting It has represented the following:
La figura número 1 y única.- Muestra una vista en sección de un rodillo al que se ha incorporado un ejemplo de realización del sensor de velocidad y cadencia de giro, objeto de la invención, apreciándose en ella las principales partes y elementos que comprende, así como su configuración y disposición.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
A la vista de la dicha figura 1 , y de acuerdo con la numeración adoptada, se puede apreciar en ella un ejemplo no limitativo del sensor de la invención, el cual comprende las partes y elementos que se indican y describen en detalle a continuación. In view of said figure 1, and according to the numbering adopted, a non-limiting example of the sensor of the invention can be seen, which comprises the parts and elements that are indicated and described in detail below.
Así, tal como se observa en dicha figura 1 , el sensor (1 ) en cuestión, es aplicable para medir la velocidad y cadencia de giro de un elemento (2) que gira alrededor de un eje (3), por ejemplo en ciclismo, la velocidad de giro de la rueda de una bicicleta situada sobre una estructura de rodillos y la cadencia de pedaleo, donde uno de dichos rodillos es el citado elemento (2) que gira, mediante rodamientos (4) sobre un eje (3) fijo. Thus, as seen in said figure 1, the sensor (1) in question is applicable to measure the speed and cadence of rotation of an element (2) that rotates around an axis (3), for example in cycling, the speed of rotation of the wheel of a bicycle placed on a roller structure and the pedaling cadence, where one of said rollers is the said element (2) that rotates, by means of bearings (4) on a fixed axis (3).

For this, the sensor (1) comprises one or more magnets (11), preferably incorporated into a support (10) that is incorporated, joined together, to the element (2) that rotates around the axis (3), and to which radially coupled magnets (11) linked to at least one coil (12) of copper or similar conductive material, connected, in turn, by wiring (13) to a component or electronic board (14) that collects the reading of electrical signals and electromagnetic force generated with the rotation and where, preferably, said electronics (14) is fed by the own electricity induced in the coil (12) by the magnets (11).
Así, cuando el elemento (2) al que se une el soporte (10) y que gira alrededor del eje (3) es uno de los rodillos de una estructura de rodillos para bicicletas, el sensor (1 ) permite medir la velocidad de giro de la rueda de la bicicleta que se incorpora a dicha estructura y la cadencia de pedaleo aplicada.

Opcionalmente, sin embargo, el elemento (2) al que se une el soporte (10) y que gira alrededor del eje (3), también puede ser el propio buje de la rueda y, en general, cualquier otro elemento. Optionally, however, the element (2) to which the support (10) joins and which rotates around the axis (3), can also be the hub of the wheel itself and, in general, any other element.
En cualquier caso, el sensor (1 ), al contar con generación propia de alimentación, es susceptible de acoplarse a otros dispositivos de medición, por ejemplo sensores de temperatura, vibración, etc, sirviendo como alimentación de los mismos.

Además, mediante el procesado de la medida de velocidad, el sensor es capaz de determinar ratios como: In addition, by processing the speed measurement, the sensor is able to determine ratios such as:
