SISTEMA DE VIDEO ANTICIPACION Y VIGILANCIA PARA EL TRANSPORTE FERROVIARIO  ANTICIPATION AND SURVEILLANCE VIDEO SYSTEM FOR RAILWAY TRANSPORTATION
D E S C R I P C I Ó N D E S C R I P C I Ó N
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a un sistema de videoanticipación y vigilancia para el transporte ferroviario, especialmente concebido para permitir advertir con la suficiente antelación a trenes en circulación, de cualquier anomalía en las vías, en orden a que éstos puedan actuar con la suficiente anticipación como para permitir impedir un accidente. The present invention relates to a video-participation and surveillance system for rail transport, specially designed to allow trains in traffic to be warned in advance of any anomaly on the tracks, in order that they can act sufficiently in advance as to allow to prevent an accident.
La invención se sitúa pues en el ámbito de los sistemas de seguridad ferroviarios. The invention thus falls within the scope of railway safety systems.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Como es sabido, en el ámbito de aplicación práctica de la invención, el de los trenes ferroviarios, éstos presentan una importante volumetría y peso que hace que los mismos cuando se desplazan alcancen una elevada inercia, de manera que las maniobras de frenado del tren, hasta la completa parada del mismo requieren de una distancia considerable. As is known, in the field of practical application of the invention, that of railway trains, they have an important volumetry and weight that makes them reach high inertia, so that train braking maneuvers, until the complete stop of the same they require a considerable distance.
Así pues, y ante un obstáculo ocasional, como puede ser la caída de un árbol, el desprendimiento de rocas o cualquier otro elemento que pueda obstaculizar las vías, el tiempo que transcurre desde que el maquinista advierte de la existencia de dicho obstáculo, hasta realizar la maniobra de frenado de emergencia, en muchos casos no resulta suficiente como para asegurar que el tren no impacte contra dicho obstáculo antes de su parada total. Esto trae consigo el tener que llevar a cabo unas labores de vigilancia continua del estado de las vías, las cuales no siempre son lo suficientemente eficaces, de manera que ante el descubrimiento de algún obstáculo se avisa al centro de control, para que éste, a través del sistema de radio, avise al correspondiente tren para que lleve a cabo la correspondiente maniobra de frenado. Thus, and before an occasional obstacle, such as the fall of a tree, the detachment of rocks or any other element that may hinder the tracks, the time that elapses since the driver warns of the existence of said obstacle, until performing the maneuver of emergency braking, in many cases it is not enough to ensure that the train does not hit the obstacle before its total stop. This entails having to carry out continuous monitoring of the state of the roads, which are not always efficient enough, so that in the event of the discovery of an obstacle, the control center is notified, so that it through the radio system, notify the corresponding train to carry out the corresponding braking maneuver.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
El sistema de videoanticipación y vigilancia para el transporte ferroviario que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, de manera que mediante el mismo es posible prescindir de las fases de alerta al centro de control, y de éste último al tren que se aproxima al obstáculo, permitiendo advertir a dicho tren de forma directa, con la suficiente antelación, y a través de la propia catenaria. The video-participation and surveillance system for rail transport that the invention proposes solves in a completely satisfactory way the problem described above, so that through it it is possible to dispense with the alert phases to the control center, and from the latter to the train that Approaches the obstacle, allowing to warn said train directly, well in advance, and through the catenary itself.
Para ello, y de forma más concreta, el sistema que se preconiza está constituido a partir de una pluralidad de videocámaras, convenientemente instaladas en los postes de sujeción de las catenarias, cada cierta distancia a lo largo de toda la vía y convenientemente orientadas, videocámaras cuya señal es gestionada por un circuito de control asociada a las mismas, basado en la tecnología OFMD (Ortogonal Frecuency-Division Multiplexing), mediante el cual se transmite la señal recibida por las videocámaras, a través de la línea catenaria de tensión, de manera que el tren que circula por dicha vía incorporará un circuito complementario asociado a su pantógrafo, a través del cual se podrán recibir las señales provenientes de las videocámaras con el tren en movimiento, para ser visualizadas a través de una pantalla situada junto al panel de mandos del tren. Así pues, a partir de esta estructuración, es posible que el maquinista de un tren pueda advertir la existencia de un obstáculo con suficiente antelación como para poder realizar las maniobras de frenado sin riesgo alguno, como por ejemplo, 10 kilómetros antes de llegar al obstáculo. El sistema descrito se complementará con un software de programación, a través del cual se selecciona automáticamente la señal que se emite a través de la pantalla del cuadro de mandos correspondiente a la videocámara que se estime más adecuada en cada momento, pudiendo no obstante ofrecer una interfaz a través de la cual se puedan seleccionar las señales provenientes de otras cámaras a lo largo de las vías. Cada imagen enviada llevará consigo información adicional acerca del kilómetro de vía de que se trate, así como cualquier otro dato que pueda ser de interés. To do this, and more specifically, the system that is recommended is constituted from a plurality of camcorders, conveniently installed in the catenary holding posts, every certain distance along the entire track and conveniently oriented, camcorders whose signal is managed by a control circuit associated with them, based on OFMD (Orthogonal Frecuency-Division Multiplexing) technology, through which the signal received by the camcorders is transmitted, through the catenary voltage line, so that the train that circulates on said route will incorporate a complementary circuit associated with your pantograph, through which you can receive the signals from the camcorders with the train in motion, to be displayed through a screen next to the train's control panel. Thus, from this structuring, it is possible that the train driver of a train can warn of the existence of an obstacle well in advance to be able to perform the braking maneuvers without any risk, such as 10 kilometers before reaching the obstacle . The described system will be complemented with a programming software, through which the signal that is emitted through the screen of the control panel corresponding to the camcorder that is deemed most appropriate at any time is selected, being able, however, to offer a interface through which signals from other cameras can be selected along the tracks. Each image sent will carry additional information about the kilometer of road in question, as well as any other data that may be of interest.
De acuerdo con otra de las características de la invención, se ha previsto que el software que controla las videocámaras esté dotado de un sistema informático de sensor de movimiento, de manera que ante la detección de un posible incidente, y a través del comentado software, se genere una señal de alerta, visualizándose el incidente a través de la repetidamente citada pantalla. According to another of the features of the invention, it is provided that the software that controls the camcorders is provided with a motion sensor computer system, so that in the event of detecting a possible incident, and through the aforementioned software, generate an alert signal, displaying the incident through the repeatedly cited screen.
