\global\parskip0.900000\baselineskip\ global \ parskip0.900000 \ baselineskip
La presente invención se refiere a un dispositivo de comprobación para tacógrafos de vehículos comerciales, más concretamente para la comprobación del buen funcionamiento o la no manipulación del sensor de movimiento de un tacógrafo.The present invention relates to a test device for vehicle tachographs commercial, more specifically for checking the good operation or non-manipulation of the motion sensor of a tachograph.
En la actualidad, los vehículos comerciales que pueden transportar a partir de cierta carga, tales como camiones, autocares, y cabezas tractoras, están obligados a llevar instalado un dispositivo tacógrafo que permite registrar el movimiento del vehículo, con el fin de asegurar unas correctas condiciones de trabajo del conductor o conductores y no incurrir en prácticas de peligro por exceso de horas de trabajo o por exceso de velocidad.At present, commercial vehicles that they can transport from a certain load, such as trucks, coaches, and tractor units, are required to carry installed a tachograph device that allows to record the movement of the vehicle, in order to ensure correct conditions of work of the driver or drivers and not incur practices danger due to excessive working hours or excessive speed.
Un tacógrafo convencional está constituido por el dispositivo registrador o tacógrafo propiamente dicho, alojado en la cabina del vehículo, un sensor de movimiento, asociado a la transmisión o a una de las ruedas del vehículo y un cable intermedio de alimentación y comunicación entre ambos. Este cable presenta tres hilos correspondientes a una masa de tensión, preferentemente el negativo de la batería, una tensión de 8 voltios de alimentación, que es suministrada por el dispositivo registrador, y un hilo de retorno o captura de los impulsos o señales que genera el sensor de movimiento al dispositivo registrador, el cual calcula a partir de estos impulsos la velocidad y el movimiento del vehículo que se debe registrar.A conventional tachograph is made up of the recording device or tachograph itself, housed in the cabin of the vehicle, a motion sensor, associated with the transmission or to one of the wheels of the vehicle and a cable intermediate power and communication between them. This cable it has three wires corresponding to a tension mass, preferably the negative of the battery, a voltage of 8 volts power supply, which is supplied by the recording device, and a return or capture thread of the impulses or signals it generates the motion sensor to the recording device, which calculates from these impulses the speed and movement of the vehicle to be registered.
Sin embargo, existen dueños y conductores de camiones que desean que parte de su conducción no quede registrada en el tacógrafo, haciendo circular el vehículo sin que el tacógrafo realice ningún registro nada. Esta práctica constituye un fraude y una competencia desleal, que puede ser penado con severas multas si es descubierto.However, there are owners and drivers of trucks that want part of their driving not registered on the tachograph, circulating the vehicle without the tachograph Do not register anything. This practice constitutes fraud and unfair competition, which can be punished with severe fines if It is discovered.
La mayoría de los fraudes se llevan a cabo mediante la manipulación del sensor de movimiento, de forma que se consigue evitar o modificar el envío al dispositivo registrador de impulsos eléctricos, correspondientes al movimiento del vehículo. Esta manipulación no se puede detectar en las inspecciones y certificaciones de funcionamiento por parte de los talleres, ya que no existen disponibles dispositivos que permitan esta comprobación de forma fácil y fiable, basándose dicha inspección y certificación a que el dispositivo registrador esté en buenas condiciones de funcionamiento y los precintos que presenta no se hayan manipulado.Most frauds take place by manipulating the motion sensor, so that it manages to avoid or modify the sending to the recording device of electrical impulses, corresponding to the movement of the vehicle. This manipulation cannot be detected in inspections and Certifications of operation by the workshops, since there are no devices available that allow this check easily and reliably, based on such inspection and certification that the recording device is in good condition for operation and the seals it presents have not been manipulated.
El dispositivo de comprobación para tacógrafos, objeto de esta invención, presenta unas particularidades técnicas que permiten la correcta evaluación del funcionamiento del sensor de movimiento del tacógrafo.The checking device for tachographs, object of this invention, presents some technical peculiarities that allow the correct evaluation of the sensor operation of movement of the tachograph.
En efecto, el dispositivo comprende una fuente de alimentación estabilizada alimentada por una batería, un testigo de alimentación y un indicador de impulsos, asociados a un conector. Este dispositivo es apto para su conexión directa mediante el conector al sensor de movimiento del tacógrafo, alimentándolo y capturando los impulsos generados en su funcionamiento, simulando un dispositivo registrador convencional. Así al realizar la inspección o comprobación, se sustituye en el cable del sensor de movimiento el dispositivo registrador por el dispositivo de la invención, y se alimenta éste sensor de movimiento desde la propia batería del vehículo, adaptando la alimentación a la necesaria, a unos 8 voltios, por el sensor de movimiento para su funcionamiento. Esta adaptación se realiza mediante un regulador de tensión debidamente estabilizado y protegido.In effect, the device comprises a source of stabilized power powered by a battery, a warning light supply and an impulse indicator, associated with a connector This device is suitable for direct connection via the connector to the motion sensor of the tachograph, feeding it and capturing the impulses generated in its operation, simulating a conventional recording device. So when performing the inspection or verification, it is replaced in the motion sensor cable the recording device by the device of the invention, and this sensor is fed movement from the vehicle's own battery, adapting the power to the necessary, about 8 volts, by the sensor movement for its operation. This adaptation is done through a properly stabilized voltage regulator and protected.
Para constatar que dicha alimentación se realiza correctamente el testigo de alimentación incorporado debe indicarlo, por ejemplo mediante un diodo LED con su correspondiente carga que ilumina al someterse a una tensión correcta.To verify that this feeding is done correctly the built-in power indicator must indicate it, for example by means of an LED with its corresponding load that illuminates when subjected to a correct tension.
El indicador de impulsos está dispuesto entre el terminal de alimentación y el terminal de captura de impulsos, y puede estar constituido de forma simple mediante un diodo LED y su correspondiente resistencia de carga, con lo que es fácilmente observable el funcionamiento correcto del sensor de movimiento cuando se mueve el vehículo porque el diodo LED parpadea en correspondencia con los impulsos generados.The pulse indicator is arranged between the power terminal and pulse capture terminal, and It can be constituted simply by means of an LED and its corresponding load resistance, so it is easily observable correct operation of the motion sensor when the vehicle is moving because the LED flashes correspondence with the impulses generated.
