Procedimiento de calculo de un intervalo de posiciones de un vehlcuio ferroviario sobre una via ferrea y dispositivo asociado 5Procedure for calculating a range of positions of a railway vehicle on a railway track and associated device 5
[0001] La presente invencion se refiere a un procedimiento de calculo de un intervalo de posiciones de un[0001] The present invention relates to a method of calculating a range of positions of a
vehlcuio ferroviario sobre una via ferrea, dicho intervalo de posiciones correspondiendo a un segmento de la via entre una extremidad delantera y una extremidad trasera.railway vehicle on a railway track, said range of positions corresponding to a segment of the track between a front limb and a rear limb.
10 [0002] La invencion se aplica al ambito de la seguridad ferroviaria, en particular a los sistemas de control10 [0002] The invention applies to the field of railway safety, in particular control systems
automatico del trafico ferroviario. Dichos sistemas son, por ejemplo, los llamados sistemas «de control de trenes basados en comunicaciones», CBTC (del ingles Communication Based Train Control»).automatic rail traffic. Such systems are, for example, the so-called "train-based communication control systems", CBTC (Communication Based Train Control).
[0003] De forma clasica, para un vehlculo ferroviario que circula sobre una via ferrea, el intervalo de 15 posiciones del vehlculo sobre la via ferrea esta determinado por un calculador embarcado a bordo del vehlculo. El[0003] Classically, for a railway vehicle that circulates on a railway, the range of 15 positions of the vehicle on the railway is determined by a calculator on board the vehicle. He
intervalo de posiciones del vehlculo se envla a continuacion, por ejemplo, mediante ondas de radio, a un ordenador central en el suelo. El ordenador en el suelo esta adaptado para recibir el intervalo de posiciones de una pluralidad de vehlculos ferroviarios y para ordenar la marcha o la parada de cada vehlculo en funcion del intervalo de posiciones de los otros vehlculos y de otros puntos de tensiones presentes sobre la via. Por ejemplo un cambio de 20 agujas mal posicionado conducira al ordenador en el suelo a ordenar la parada de los trenes que se acercan a ese cambio de agujas.The vehicle's range of positions is then sent, for example, by radio waves, to a central computer on the ground. The computer on the ground is adapted to receive the range of positions of a plurality of railway vehicles and to order the progress or stop of each vehicle based on the range of positions of the other vehicles and other stress points present on the track . For example, a change of 20 badly positioned needles will lead the computer on the ground to order the stop of the trains that approach that needle change.
[0004] Por «intervalo de posiciones», se entiende en el sentido de la presente invencion un segmento de una via ferrea en el que el vehlculo ferroviario es susceptible de encontrarse con una incertidumbre inferior a un umbral[0004] "Interval of positions" means in the sense of the present invention a segment of a railway track in which the railway vehicle is capable of encountering an uncertainty below a threshold

[0005] El calculador embarcado esta adaptado para determinar la posicion del vehlculo a partir por ejemplo de balizas dispuestas sobre la via ferrea, y cuyos emplazamientos sobre la via ferrea se conocen previamente. Mas precisamente, el calculador embarcado determina el intervalo de posiciones del vehlculo ferroviario a partir del[0005] The on-board calculator is adapted to determine the position of the vehicle from, for example, beacons arranged on the railway, and whose locations on the railway are previously known. More precisely, the on-board calculator determines the range of positions of the rail vehicle from the
30 emplazamiento de la ultima baliza encontrada y del desplazamiento del vehlculo a partir de esta ultima baliza, dicho desplazamiento siendo medido por ejemplo por un odometro.30 location of the last beacon found and the displacement of the vehicle from this last beacon, said displacement being measured for example by an odometer.
[0006] En ciertas situaciones, el calculador embarcado deja de estar en condiciones de calcular el intervalo de posiciones del vehlculo ferroviario con una precision suficiente. En ese caso se habla de perdida de localizacion.[0006] In certain situations, the on-board calculator is no longer able to calculate the range of positions of the railway vehicle with sufficient accuracy. In that case there is talk of loss of location.
35 Una perdida de localizacion ocurre por ejemplo si no se ha detectado ninguna baliza nueva despues de que el vehlculo ferroviario haya recorrido una distancia superior o igual a un umbral predeterminado, desde la ultima baliza detectada. Por razones de seguridad, un sistema de control del vehlculo ferroviario ordena entonces la parada del vehlculo.35 A loss of location occurs, for example, if no new beacon has been detected after the rail vehicle has traveled a distance greater than or equal to a predetermined threshold, since the last beacon detected. For safety reasons, a rail vehicle control system then orders the vehicle to stop.
40 [0007] En caso de parada del vehlculo ferroviario, es habitual hacer intervenir a un operario para maniobrar40 [0007] In the event of a stop of the railway vehicle, it is usual to have an operator intervene to maneuver
manualmente el vehlculo ferroviario parado y enviarlo hasta la siguiente baliza funcional, para que el calculadormanually stop the rail vehicle and send it to the next functional beacon, so that the calculator
embarcado determine de nuevo el intervalo de posiciones del vehlculo para permitir un regreso al funcionamiento autonomo y automatico del vehlculo ferroviario.embarked to determine again the range of positions of the vehicle to allow a return to the autonomous and automatic operation of the railway vehicle.
45 [0008] Tambien es habitual permitir a un operario que se encuentre lejos que maniobre el vehlculo ferroviario,[0008] It is also customary to allow an operator who is far away to maneuver the rail vehicle,
despues de que el operario haya verificado la ausencia de obstaculos en la direccion hacia la que desea enviar el vehlculo ferroviario. Como anteriormente, se recupera un funcionamiento automatico desde que el vehlculo ferroviario encuentra una baliza funcional.after the operator has verified the absence of obstacles in the direction to which he wishes to send the rail vehicle. As before, an automatic operation is recovered since the railway vehicle finds a functional beacon.

[0010] Sin embargo, dichos procedimientos no ofrecen una satisfaction completa.[0010] However, such procedures do not offer complete satisfaction.
55 [0011] De hecho, dichos procedimientos necesitan la intervention de un operario, lo que es susceptible de55 [0011] In fact, such procedures require the intervention of an operator, which is susceptible to
producir incidentes relacionados con los errores humanos. Ademas, dichos procedimientos implican la inmovilizacion del vehlculo ferroviario durante largos ratos, por ejemplo, el tiempo que dura la intervencion del operario, lo que todavla es mas perjudicial para los sistemas de transporte sin conductor. Esto perjudica a la calidad del trafico, en concreto en las redes de transporte urbanas.produce incidents related to human errors. In addition, such procedures involve the immobilization of the rail vehicle for long periods, for example, the duration of the operator's intervention, which is still more harmful for driverless transport systems. This hurts the quality of traffic, particularly in urban transport networks.
[0012] Un objetivo de la invencion es por tanto proponer un procedimiento de localizacion de un vehlcuio ferroviario que permite un funcionamiento seguro y automatizado, y un restablecimiento rapido del trafico ferroviario en caso de perdida de localizacion.[0012] An objective of the invention is therefore to propose a procedure for locating a railway vehicle that allows safe and automated operation, and a rapid restoration of railway traffic in the event of a location loss.

Por ejemplo, en el caso de los instrumentos de medicion adaptados para medir el desplazamiento del vehlculo ferroviario 2, el calculador embarcado 10 es capaz de determinar la velocidad del vehlculo ferroviario 2 por derivation respecto del tiempo de desplazamiento. Por ejemplo, en el caso de los instrumentos de medicion adaptados para medir la velocidad 10 instantanea de desplazamiento del vehlculo ferroviario 2, el calculador embarcado 10 es capaz de calcular la distancia recorrida por el vehlculo ferroviario 2 por derivacion respecto del tiempo de la velocidad del vehlculo ferroviario 2. Por ejemplo, en el caso de los instrumentos de medicion adaptados para medir la aceleracion instantanea del vehlculo ferroviario 2, el calculador embarcado 10 es capaz de calcular la velocidad del vehlculo ferroviario 2, y despues la distancia recorrida por el vehlculo ferroviario 2, mediante integraciones sucesivas respecto 15 del tiempo de la aceleracion del vehlculo ferroviario 2.measurement in a measurement of displacement and / or speed of the railway vehicle 2. For example, in the case of measuring instruments adapted to measure the displacement of the railway vehicle 2, the on-board calculator 10 is capable of determining the speed of the railway vehicle 2 by derivation with respect to travel time. For example, in the case of measuring instruments adapted to measure the instantaneous speed of travel of the railway vehicle 2, the on-board calculator 10 is able to calculate the distance traveled by the railway vehicle 2 by derivation with respect to the time of the speed of the railway vehicle 2. For example, in the case of measuring instruments adapted to measure the instantaneous acceleration of railway vehicle 2, the on-board calculator 10 is able to calculate the speed of railway vehicle 2, and then the distance traveled by the railway vehicle 2, by successive integrations with respect to 15 of the acceleration time of the rail vehicle 2.
[0034] El calculador embarcado 10 es igualmente capaz de calcular un intervalo de posiciones S0 del vehlculo ferroviario 2. Como ilustra la figura 2, el intervalo S0 corresponde a un segmento de extremidad delantera A0 y de extremidad trasera Z0. En concreto, el calculador embarcado 10 es capaz de calcular un intervalo S0 del[0034] The on-board calculator 10 is also capable of calculating a range of positions S0 of the railway vehicle 2. As Figure 2 illustrates, the interval S0 corresponds to a segment of the front end A0 and the rear end Z0. Specifically, the on-board calculator 10 is able to calculate an interval S0 of the
20 vehlculo ferroviario 2 a partir del emplazamiento de la ultima baliza detectada por el detector de baliza. En particular, el calculador embarcado 10 es capaz de determinar un intervalo S0 del vehlculo ferroviario 2 a partir del emplazamiento de la ultima baliza detectada y del desplazamiento del vehlculo ferroviario desde dicha ultima baliza detectada, el desplazamiento siendo medido por los instrumentos de medicion del vehlculo ferroviario 2 o calculado por el calculador embarcado 10 a partir de las mediciones realizadas por los instrumentos de medicion del vehlculo 25 ferroviario 2. Ventajosamente, el calculador embarcado 10 es capaz de tener en cuenta, durante el calculo del intervalo S0, un margen de error potencial relacionado con la precision de los instrumentos de medicion utilizados, lo que conduce a un calculo seguro del intervalo de position S0. Por ejemplo, en el caso de un odometro, el margen de error tiene en cuenta el coeficiente de adherencia entre una rueda del vehlculo ferroviario 2 y un rail de la via ferrea 4, no siendo este coeficiente del 100 %.20 railway vehicle 2 from the location of the last beacon detected by the beacon detector. In particular, the on-board calculator 10 is able to determine an interval S0 of the railway vehicle 2 from the location of the last beacon detected and the displacement of the railway vehicle from said last beacon detected, the displacement being measured by the measuring instruments of the vehicle rail 2 or calculated by the on-board calculator 10 from the measurements made by the measuring instruments of the railway vehicle 25 2. Advantageously, the on-board calculator 10 is able to take into account, during the calculation of the interval S0, a margin of error potential related to the accuracy of the measuring instruments used, which leads to a safe calculation of the position range S0.

[0035] El calculador embarcado 10 ademas es capaz de generar una senal de alerta en caso de perdida de localization. Por «perdida de localizations se entiende una situation en la que los datos recibidos por el calculador embarcado 10 no permiten determinar el intervalo de posiciones S0 del vehlculo ferroviario 2 con un error inferior a un umbral predeterminado. El calculador embarcado 10 esta por ejemplo configurado para generar una senal de[0035] The on-board calculator 10 is also capable of generating an alert signal in case of loss of localization. “Loss of localizations means a situation in which the data received by the on-board calculator 10 does not allow determining the range of positions S0 of the railway vehicle 2 with an error below a predetermined threshold. The on-board calculator 10 is for example configured to generate a signal of
