Esta invención tiene su aplicación dentro de la industria electrónica y de las telecomunicaciones.This invention has its application within the electronics and telecommunications industry.
Uno de los mayores problemas que presentan las redes de comunicación por cable es que pueden quedar completamente bloqueadas si se produce una avería en un punto de la red que provoque un cortocircuito eléctrico o bien se produce un exceso de consumo eléctrico por avería en alguna de las estaciones de control remoto.One of the biggest problems presented by cable communication networks is that they can be completely blocked if a fault occurs at a point in the network that cause an electrical short circuit or an excess of power consumption due to breakdown in any of the control stations remote.
Actualmente no se tiene constancia de la existencia de ningún equipo en el mercado que permita habilitar y deshabilitar automáticamente los distintos ramales de una red de comunicación por cable que tengan sus equipos de control dispersos en un área geográfica que puede ser muy extensa.There is currently no record of the existence of any equipment in the market that allows to enable and automatically disable the different branches of a network Cable communication that has scattered control equipment in a geographical area that can be very extensive.
Frente a ello, la invención que se propone consiste en un supervisor de línea para red de estaciones de control remotas interconectadas por medio de cable eléctrico que, ante la eventualidad de que se produzca un fallo en la red, desconecta automáticamente el ramal en el que se ha originado el problema y permite al resto de la red seguir en funcionamiento normal.Against this, the proposed invention consists of a line supervisor for network of stations remote control interconnected by means of electric cable that, in the event of a network failure, automatically disconnects the branch where the problem and allows the rest of the network to remain operational normal.
Por otra parte, este equipo se encuentra en comunicación con el centro de control, al cual informa del estado de la red y de las actuaciones realizadas, y del que a su vez puede recibir instrucciones de actuación.Moreover, this team is in communication with the control center, which reports status of the network and of the actions carried out, and of which in turn it can Receive acting instructions.
El supervisor de línea para red de estaciones de control remotas interconectadas por medio de cable eléctrico que la presente invención propone es un aparato electrónico que permite proteger la red frente a averías o fallos en puntos determinados de la red, ya que es capaz de desconectar automáticamente el ramal en el que se ha producido el problema para que el resto de la red continúe operativa, evitando, por lo tanto, la pérdida de comunicaciones o de funcionamiento de las estaciones de control remoto que no se encuentran conectadas directamente en el cable afectado.The line supervisor for the network of stations remote control interconnected by means of electric cable that the The present invention proposes is an electronic device that allows protect the network against breakdowns or failures at certain points of the network, since it is able to automatically disconnect the branch in the one that has occurred the problem so that the rest of the network continue operational, thus avoiding the loss of communications or operation of control stations remote that are not connected directly to the cable affected.
En particular, este equipo puede ser instalado en los nodos de ramificación de la red, para controlar varios ramales simultáneamente, pudiendo habilitar o deshabilitar cada ramal de forma independiente.In particular, this equipment can be installed in network branch nodes, to control several branches simultaneously, being able to enable or disable each branch of independently.
Adicionalmente, el supervisor de línea se encuentra en comunicación con el centro de control de la red, el cual puede enviarle instrucciones de habilitar o deshabilitar ramales de la red, según convenga para el buen funcionamiento del sistema, realizar actuaciones de mantenimiento, utilizar ramales redundantes de seguridad o emergencia, etc.Additionally, the line supervisor will is in communication with the network control center, the which can send you instructions to enable or disable network branches, as appropriate for the proper functioning of the system, perform maintenance actions, use branches redundant security or emergency, etc.
La red de cable que incluye estos elementos supervisores de línea opera a modo de bus inteligente.The cable network that includes these elements Line supervisors operate as a smart bus.
El supervisor de línea (6) para red de estaciones de control remotas interconectadas por medio de cable eléctrico, se conforma a partir de un circuito de supervisión (2), un circuito de comunicaciones (3) e interruptores de línea (4), intercalándose en el circuito, para lo cual presenta una conexión para la línea (1) de cable que viene desde la cabecera de la red (estación central) y un número de conexiones para las líneas (5) de cable que van hacia las estaciones de control remoto. De esta forma, este elemento puede ser colocado en cualquier nodo de bifurcación de la red para controlar las líneas que salen de dicho nodo.The line supervisor (6) for station networks of remote control interconnected by means of electric cable, it conforms from a supervision circuit (2), a circuit of communications (3) and line switches (4), intercalating in the circuit, for which it presents a connection for the line (1) of cable coming from the network header (central station) and a number of connections for the cable lines (5) that go to The remote control stations. In this way, this element can be placed on any branch node of the network to control the lines that leave said node.
Dichas líneas de salida (5) pueden ser un número indefinido de líneas de salida.Said output lines (5) can be a number undefined output lines.
El circuito de supervisión (2) monitoriza el estado físico de la línea de entrada (1): intensidad y tensión eléctrica. Los valores de estas variables son monitorizados por el elemento, y en el caso de que detecte valores fuera de rango, automáticamente actúa sobre los interruptores de línea (4) y desconecta todas las líneas de salida (5).The supervision circuit (2) monitors the physical state of the input line (1): intensity and voltage electric The values of these variables are monitored by the element, and in case it detects out of range values, automatically acts on the line switches (4) and disconnect all output lines (5).
A continuación el elemento prueba a conectar una a una las líneas de salida (5), actuando consecutivamente sobre cada interruptor (4), con el objeto de comprobar cuál o cuáles de las líneas de salida provocan la avería al ser conectadas. De esta forma son identificadas las líneas problemáticas y se dejan desconectadas para que no afecten al resto de la red, que se mantiene operativa.Then the element tries to connect a to one the output lines (5), acting consecutively on each switch (4), in order to check which or which of the output lines cause the fault to be connected. This way the problem lines are identified and left disconnected so that they do not affect the rest of the network, which It remains operational.
