ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

Dada la importancia que están tomando las redes de trasporte de gran capacidad y velocidad terrestres, bien sean autovías o autopistas, o las líneas de alta velocidad, en las que se centra la invención, aunque es Given the importance that land transport networks of great capacity and speed are taking, whether they are highways or highways, or high-speed lines, on which the invention focuses, although it is

extrapolable a todas las líneas de ferrocarril, y sus compromisos de seguridad, fiabilidad y puntualidad, que son altamente selectivos para este medio de trasporte, también se conoce que existen fenómenos atmosféricos no controlados e imprevisibles que pueden descargar gran cantidad de agua en un punto concreto de un trazado, dejando el tramo parcial o totalmente inhábil en cuestión de minutos. Este hecho aislado no tendría importancia si desde el punto de vista de seguridad se conociera en que punto y momento se está produciendo este fenómeno. Extrapolable to all railway lines, and their safety, reliability and punctuality commitments, which are highly selective for this means of transportation, it is also known that there are uncontrolled and unpredictable atmospheric phenomena that can discharge large amounts of water at a specific point. of a path, leaving the section partially or totally non-working in a matter of minutes. This isolated fact would not matter if from the security point of view it was known at what point and moment this phenomenon is occurring.

DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION

El sistema que se preconiza ha sido previsto precisamente para controlar en espacio y tiempo real las variables comentadas en el apartado anterior, pudiendo obrar en consecuencia antes de que haya que lamentar pérdidas humanas y materiales, que por otro lado son inevitables si el estado del trazado no es supervisado, ya que dadas las velocidades y masas que se desarrollan actualmente, no es posible detener un tren en la distancia de visión de un obstáculo. The system that has been recommended has been precisely designed to control the variables mentioned in the previous section in real time and space, and can act accordingly before it is necessary to regret human and material losses, which on the other hand are unavoidable if the state of the layout it is not supervised, since given the speeds and masses that are currently developing, it is not possible to stop a train in the viewing distance of an obstacle.

Mas concretamente, el sistema de la invención se basa en instalar a distintas alturas en los correspondientes postes de la catenaria, sondas de nivel, así como un detector de impactos y vibraciones, todo ello complementado con un autómata programable que gestiona cada tramo vigilado, y un sistema que integra las señales de alarma en el actual sistema de comunicaciones. More specifically, the system of the invention is based on installing at different heights in the corresponding catenary posts, level probes, as well as an impact and vibration detector, all complemented by a programmable automaton that manages each monitored section, and a system that integrates the alarm signals in the current communications system.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION

25 25
Como se puede ver en la figura referida, el sistema de la invención es aplicable a vías de ferrocarril en las que bajo los correspondientes carriles (1) está establecida la respectiva plataforma de balasto (2), vía de ferrocarril que se complementa con los clásicos postes (3) de catenaria (4), todo ello como es convencional. As can be seen in the aforementioned figure, the system of the invention is applicable to railroad tracks in which the respective ballast platform (2) is established under the corresponding rails (1), a railway track that is complemented with the classic posts (3) of catenary (4), all as conventional.

Según el sistema de la invención, en el tramo inferior de los postes    According to the system of the invention, in the lower section of the posts

(3), es decir el que va empotrado en el balasto (2) y queda lógicamente por debajo del carril (1), se han previsto, para cada poste, tres sensores (5, 6 y 7), a distinta cota, cotas que corresponden a un nivel bajo el carril (1), a un nivel intermedio y a un nivel inferior, respectivamente, de manera que esos sensores (5, 6 y 7) establecen tres niveles de actuación en el que el principio de funcionamiento es como sigue: (3), that is, the one that is embedded in the ballast (2) and is logically below the rail (1), three sensors (5, 6 and 7), at different levels, are provided for each post corresponding to a level under the rail (1), to an intermediate level and to a lower level, respectively, so that these sensors (5, 6 and 7) establish three levels of action in which the principle of operation is as follows :

Si dos sensores (7) consecutivos del nivel inferior detectan agua, se activa la señal de aviso por presencia de agua en la base de la plataforma de balasto (2). If two consecutive sensors (7) of the lower level detect water, the warning signal is activated due to the presence of water at the base of the ballast platform (2).

Si con la señal de alarma referida se activan sensores respectivos (6), es decir correspondientes al nivel intermedio, se activa la alarma por presencia importante de aguas sobre la plataforma de balasto (2). If the respective sensors are activated with the referred alarm signal (6), that is, corresponding to the intermediate level, the alarm is activated due to the significant presence of water on the ballast platform (2).

Por último, si con esas dos señales de alarma referidas de los niveles inferior e intermedio, se dispara un sensor (5) del nivel superior, la señal de alarma por inundación completa bajo las vías se haría efectiva. Finally, if with those two referred alarm signals of the lower and intermediate levels, a sensor (5) of the upper level is triggered, the full flood alarm signal under the tracks would become effective.

Por otro lado, se ha previsto que adosados al nivel de los sensores (7), se incluyan los sensores de impacto (8), también denominados de vibración, adosados al nivel de los sensores inferiores (7), de manera que siempre y cuando exista presencia de agua, esos sensores de impacto o vibración (8) reconocen a partir de que momento el balasto (2) comienza a desplazarse de su ubicación, hacia el exterior, dejando el carril (1) sin capacidad portante o inestable frente al paso de trenes. On the other hand, it is envisaged that attached to the level of the sensors (7), the impact sensors (8), also called vibration, included at the level of the lower sensors (7) are included, so that as long as If there is a presence of water, these impact or vibration sensors (8) recognize from which moment the ballast (2) begins to move from its location, towards the outside, leaving the lane (1) without bearing or unstable capacity in front of the passage of trains.


Por lo tanto, se puede conocer en tiempo real el estado de la vía y obrar en consecuencia según el nivel de alarma detectado.

Therefore, the status of the track can be known in real time and act accordingly according to the alarm level detected.


Por último, todo el funcionamiento está basado en un autómata programable (9) mediante el que se gestiona cada tramo vigilado y en base al cual se puede reprogramar en cada momento según las necesidades, e incluso introducir nuevos tipos de alarma o sensores con posterioridad.

Finally, all the operation is based on a programmable automaton (9) through which each monitored section is managed and on the basis of which it can be reprogrammed at any time according to the needs, and even introduce new types of alarm or sensors later.
