La invención se refiere a un sistema de mantenimiento en línea (on line) para instalaciones de calentamiento por inducción y similares, que proporcionan medios de control y verificación, locales y/o remotos, de los distintos parámetros de funcionamiento del sistema de calentamiento por inducción que se materializa en un generador.The invention relates to an online maintenance system for induction heating installations and the like, which provide control and verification means, local and / or remote, of the different operating parameters of the induction heating system. that materializes in a generator.

Otro objeto de la invención consiste, por una parte en dotar al generador de medios que faciliten y simplifiquen la sustitución de los principales componentes electrónicos que lo componen, y por otra disponer un sistema teleasistencial que permite al operario del generador ser guiado por un técnico remoto en las labores de mantenimiento y servicio técnico.Another object of the invention consists, on the one hand, in providing the generator with means that facilitate and simplify the replacement of the main electronic components that compose it, and on the other, having a telecare system that allows the operator of the generator to be guided by a remote technician. in maintenance and technical service.

Para tal fin la invención permite establecer una video conferencia entre un operario local y un técnico remoto, de manera que el operario pueda mostrar partes del generador al técnico remoto, de modo que junto con los objetivos anteriormente señalados, se facilita enormemente la reparación y/o sustitución de los principales componentes electrónicos que componen el generador, efectuando la transmisión simultánea de datos, sonido y video.For this purpose, the invention allows a video conference to be established between a local operator and a remote technician, so that the operator can show parts of the generator to the remote technician, so that together with the aforementioned objectives, repair and / or or replacement of the main electronic components that make up the generator, making the simultaneous transmission of data, sound and video.

Evidentemente la invención es de especial aplicación en generadores para calentamiento por inducción empleados en múltiples aplicaciones, como por ejemplo calentamiento de metales para obtener variación de los parámetros físicos del metal, o para templar una pieza o partes de ella, etc., pero evidentemente también puede ser aplicado en cualquier dispositivo electrónico que requiera un mantenimiento constante y especializado. ANTECEDENTES DE LA INVENCIÓN En el estado de la técnica son sobradamente conocidos los generadores para calentamiento por inducción que se basan en la generación de un campo magnético de corriente alterna para efectuar el calentamiento de metales . El calentamiento producido varía en función de los parámetros de la corriente generadora, lo que permite controlar con gran exactitud dicho calentamiento.Obviously the invention is of special application in generators for induction heating used in multiple applications, such as metal heating to obtain variation of the physical parameters of the metal, or to temper a piece or parts thereof, etc., but obviously also It can be applied to any electronic device that requires constant and specialized maintenance. BACKGROUND OF THE INVENTION In the state of the art they are amply known are the generators for induction heating that are based on the generation of a magnetic field of alternating current to effect the heating of metals. The heating produced varies depending on the parameters of the generating current, which allows the heating to be controlled with great accuracy.

Estos equipos son muy complejos y requieren un mantenimiento constante y especializado. Básicamente los generadores cuentan con una serie de módulos de potencia, que en la mayoría de las aplicaciones se refrigeran mediante un circuito de agua, para lo que los módulos de potencia están dispuestos sobre unos radiadores refrigerados por agua. Además cuentan con la acometida eléctrica y conectores de comunicación entre módulos. Todo el conjunto está ubicado en un armario que incluye las tomas de entrada y salida de agua, así como la acometida eléctrica y conectores de comunicación. Además en el armario se incluyen los diferentes elementos que posibilitan el correcto funcionamiento del generador, y que no es necesario comentarlos por ser sobradamente conocidos y por no aportar una mejor comprensión de la novedad de la invención que nos ocupa.These equipments are very complex and require constant and specialized maintenance. Basically, the generators have a series of power modules, which in most applications are cooled by a water circuit, for which the power modules are arranged on water-cooled radiators. They also have the electrical connection and communication connectors between modules. The whole set is located in a closet that includes the water inlet and outlet sockets, as well as the electrical connection and communication connectors. In addition, the different elements that enable the correct operation of the generator are included in the cabinet, and that it is not necessary to comment on them because they are well known and for not providing a better understanding of the novelty of the invention that concerns us.

En el momento en el que alguno de los módulos refrigerados sufre una avería, su reparación y/o sustitución es muy complicada y precisa que se efectúe por técnicos especializados en la mayoría de las ocasiones, dado el elevado número de componentes electrónicos de que consta, lo que obliga a que los técnicos especializados se trasladen hasta el lugar donde esté instalado el generador.At the time when any of the refrigerated modules suffers a breakdown, their repair and / or replacement is very complicated and precise to be carried out by specialized technicians in most cases, given the high number of electronic components that it consists of, which forces specialized technicians to move to the place where the generator is installed.

DESCRIPCIÓN DE LA INVENCIÓN Para resolver los inconvenientes anteriormente indicados, la invención aporta mejoras en los generadores para calentamiento de metales del tipo de los descritos en el apartado anterior, en los que una de las mejoras reside en el hecho de que los módulos de potencia están montados en diferentes placas que se sujetan a una guía telescópica, que a su vez se soportan en el bastidor del armario; en el que además se incluye al menos un conector por cada módulo, del que emerge al menos un conector dispuesto en correspondencia con el del bastidor. Los conectores son de potencia, dada la aplicación.DESCRIPTION OF THE INVENTION To solve the aforementioned drawbacks, the invention provides improvements in the generators for heating metals of the type described in the previous section, in which one of the improvements lies in the fact that the power modules are mounted on different plates that are attached to a telescopic guide, which in turn are supported on the cabinet frame; which also includes at least one connector for each module, from which at least one connector arranged in correspondence with that of the rack emerges. The connectors are power, given the application.

Además, cuando los módulos de potencia están refrigerados, cada placa está dotada de conexiones rápidas de entrada y salida de agua al circuito de refrigeración.In addition, when the power modules are refrigerated, each board is equipped with quick water inlet and outlet connections to the cooling circuit.

Esta estructura tiene la ventaja de que en el caso de que se produzca una avería, la sustitución del módulo se efectúa tirando de éste, de modo que se desplaza la guía telescópica, y se desconecta el módulo del conector del bastidor. Además en el caso de que se refrigere por agua, se cierran las conducciones de entrada y salida de agua al armario para permitir soltar las conexiones rápidas de entrada y salida de agua al módulo, y se sustituye el módulo por uno nuevo de forma inversa a la descrita. Por consiguiente, el número de operaciones a efectuar para sustituir el módulo son mínimas, simplificándose considerablemente el proceso de recambio del mismo, y por tanto se reduce considerablemente el tiempo que se precisa para sustituir una posible placa averiada. En una realización preferida el al menos conector previsto en el bastidor por cada módulo, es un conector hembra y el del módulo es un conector macho .This structure has the advantage that in the event of a breakdown, the module is replaced by pulling it, so that the telescopic guide is moved, and the module is disconnected from the frame connector. In addition, in the case of water cooling, the water inlet and outlet pipes are closed to the cabinet to allow quick release of water inlet and outlet connections to the module, and the module is replaced with a new one in reverse the one described Therefore, the number of operations to be carried out to replace the module is minimal, considerably simplifying the process of replacing it, and therefore considerably reducing the time required to replace a possible damaged plate. In a preferred embodiment, the at least one connector provided in the frame for each module is a female connector and that of the module is a male connector.

Las placas están dispuestas verticales y paralelas para favorecer la refrigeración, para lo que las guías telescópicas van fijadas al bastidor paralelas y horizontales .The plates are arranged vertically and parallel to favor cooling, for which the telescopic guides are fixed to the parallel and horizontal frame.

Otra mejora de la invención reside en el hecho de que se ha previsto un sistema de comunicación, debidamente programado y basado en ordenador personal, que está conectado al generador y a un ordenador personal local, y/o a un ordenador personal remoto para controlar los parámetros de funcionamiento del generador local y/o remotamente y para testear en tiempo real posibles averías o mal funcionamientos . En una realización preferente el sistema de comunicación consta de una consola que está conectada a una cámara de video, para establecer una video conferencia de enlace directo (on line: RS 232, red básica telefónica, vía red local o internet) entre un operario local y un técnico remoto, de manera que el operario local pueda mostrar las partes del generador al técnico remoto, el cual además conoce los parámetros de funcionamiento del generador enviados a través del sistema de comunicación, de modo que puede solicitar al operario que realice medidas complemen- tarias en las partes que le va mostrando con la cámara para poder determinar la naturaleza de la avería, de forma que se evita que el técnico especialista tenga que desplazarse para reparar los generadores. Estos desplazamientos, por la naturaleza de los equipos, en muchas ocasiones son distan- cias muy largas, como por ejemplo es el caso de realizar reparaciones en países diferentes en los que se encuentran los técnicos especialistas. Por tanto la estructura descrita de la invención presenta la gran ventaja de que la reparación de avería se puede efectuar de forma rápida y sencilla, por el propio operario del generador, guiado por el técnico especialista teleasistido, de manera que los tiempos y costes de reparación se reducen al máximo.Another improvement of the invention lies in the fact that a communication system, duly programmed and based on a personal computer, which is connected to the generator and a local personal computer, and / or is provided to a remote personal computer to control the operating parameters of the generator locally and / or remotely and to test in real time possible failures or malfunctions. In a preferred embodiment, the communication system consists of a console that is connected to a video camera, to establish a direct link video conference (online: RS 232, basic telephone network, via local network or internet) between a local operator and a remote technician, so that the local operator can show the parts of the generator to the remote technician, who also knows the generator operating parameters sent through the communication system, so that he can request the operator to perform complementary measures - The parts that are shown with the camera to determine the nature of the fault, so that the specialist technician has to travel to repair the generators. These displacements, due to the nature of the equipment, are often very long distances, for example, in the case of repairs in different countries where specialist technicians are located. Therefore, the described structure of the invention has the great advantage that the fault repair can be carried out quickly and easily, by the generator operator himself, guided by the teleassisted specialist technician, so that repair times and costs They are reduced to the maximum.

Para conseguir toda esta funcionalidad el sistema de comunicación comprende tarjetas de adquisición de señales de alta y baja frecuencia, para mostrar al técnico remoto señales y formas de onda, así como los parámetros del estado del generador.To achieve all this functionality, the communication system comprises high and low frequency signal acquisition cards, to show the remote technician signals and waveforms, as well as the generator status parameters.

Además el sistema de comunicación cuenta con una tarjeta de adquisición de datos de alta velocidad que comprende entre otros elementos un osciloscopio para la medida de parámetros .In addition, the communication system has a high-speed data acquisition card that includes among other elements an oscilloscope for the Parameter measurement

También se ha previsto que el sistema de comunicación comprenda una tarjeta de adquisición de datos de baja velocidad empleada para medir los parámetros básicos como la apertura de la puerta, temperatura etc., la correspondiente unidad central de procesos que está conectada a la línea de comunicación y que incluye el correspondiente software necesario y el hardward para el establecimiento de la video conferencia mediante la cámara y los correspondientes dispositivos de audio.It is also provided that the communication system comprises a low speed data acquisition card used to measure the basic parameters such as the door opening, temperature etc., the corresponding central process unit that is connected to the communication line and that it includes the corresponding necessary software and the hardward for the establishment of the video conference by means of the camera and the corresponding audio devices.

A continuación para facilitar una mejor comprensión de esta memoria descriptiva y formando parte integrante de la misma, se acompañan una serie de figuras en las que con carácter ilustrativo y no limitativo se ha representado el objeto de la invención.Next, in order to facilitate a better understanding of this descriptive report and forming an integral part thereof, a series of figures are attached in which the object of the invention has been represented by way of illustration and not limitation.

A continuación se realiza una descripción de la invención basada en las figuras anteriormente comentadas .Below is a description of the invention based on the figures mentioned above.

El generador está alojado en un armario 1 en cuyo bastidor 2 se soportan los diferentes elementos que lo componen, como por ejemplo el cuadro de control 3, el correspondiente diferencial 4, el contactor de potencia 5, transformador de alimentación 6, toma de tierra 7, filtros 8, contactores de protección 9 fusibles 10 de protección de las tres fases, etc. Esta parte del generador no se describe en mayor detalle, por no ser objeto de la invención y ser conocida.The generator is housed in a cabinet 1 in whose frame 2 the different elements that compose it are supported, such as the control panel 3, the corresponding differential 4, the power contactor 5, power transformer 6, ground 7 , filters 8, protection contactors 9 fuses 10 for protection of the three phases, etc. This part of the generator is not described in greater detail, as it is not an object of the invention and is known.

Además el generador cuenta con una serie de módulos 11 de potencia que están refrigerados por radiado- res que forman parte de un circuito de agua.In addition, the generator has a series of power modules 11 that are cooled by radiators that are part of a water circuit.

Para realizar el circuito de refrigeración por agua, el armario 1 cuenta con las tomas de entrada y salida 13 de agua.To carry out the water cooling circuit, cabinet 1 has water inlet and outlet 13 inlets.

Los módulos están montados en diferentes placas 17 en las que se establece un circuito de refrigeración de agua, cuyos tubos 16 están dotados de unas conexiones rápidas 18 - 18'.The modules are mounted on different plates 17 in which a water cooling circuit is established, whose tubes 16 are provided with quick connections 18-18 '.

Un módulo 11 puede estar constituido por una o más placas 17, de forma que cada módulo 11 se fija a una guía telescópica 19 que se soporta en el bastidor 2, para lo que en dicho bastidor 2 se han previsto unos perfiles en "U" invertidos 20 al que se fijan, mediante unas pletinas 21, las guías telescópicas 19.A module 11 may be constituted by one or more plates 17, so that each module 11 is fixed to a telescopic guide 19 that is supported on the frame 2, for what in said frame 2 are provided with inverted "U" profiles 20 to which the telescopic guides 19 are fixed by means of plates 21.

Tal y como se aprecia en las figuras 4 y 5, las guías telescópicas 19 quedan dispuestas paralelas y horizontales, de modo que las placas 17 se disponen paralelas y verticales para facilitar la refrigeración.As can be seen in Figures 4 and 5, the telescopic guides 19 are arranged parallel and horizontal, so that the plates 17 are arranged parallel and vertical to facilitate cooling.

Además en el bastidor 2 se han previsto unos conectores hembra 22, ubicados en correspondencia con unos conectores macho 23, que sobresalen respecto a los módulos 11, para facultar la correcta conexión de los mismos al resto de los elementos que componen el generador.Furthermore, in the frame 2, female connectors 22 are provided, located in correspondence with male connectors 23, which protrude with respect to the modules 11, to enable their correct connection to the rest of the elements that make up the generator.

Por tanto, en base a la descripción realizada se comprende fácilmente que para realizar el recambio de uno de los módulos 11, basta con tirar de éstos sacando la guía telescópica 19, en cuyo desplazamiento se produce la desconexión de los conectores 22 y 23 de modo que tras desconectar las conexiones rápidas 18 - 18' del cicuito de refrigeración de agua, se faculta la extracción completa de los módulos 11, cuyo recambio se efectúa de forma inversa a la descrita. Para ello el tramo deslizable de la guía telescópica 19 es solidario del extremo superior de la placa 17.Therefore, based on the description made, it is easily understood that to carry out the replacement of one of the modules 11, it is enough to pull them out by removing the telescopic guide 19, in which displacement of the connectors 22 and 23 takes place so that that after disconnecting the quick connections 18 - 18 'from the water cooling circuit, the complete extraction of the modules 11 is authorized, the replacement of which is carried out in an inverse manner to that described. For this, the sliding section of the telescopic guide 19 is integral with the upper end of the plate 17.
