La lógica del sistema podrá realizarse de manera centralizada o distribuida: 1 . En la lógica centralizada, el procesado periódico de la información proporcionada en cada HUB (1 ) dará como resultado la generación de distintas acciones a realizar sobre las distintas cargas (o equipos inversores, de acumulación, etc.)- Estas acciones permiten actuar sobre los nodos (60) vía la transmisión de mensajes (6) donde se definen las acciones. The system logic can be performed centrally or distributed: one . In the centralized logic, the periodic processing of the information provided in each HUB (1) will result in the generation of different actions to be carried out on the different loads (or inverting, accumulation equipment, etc.) - These actions allow acting on the nodes (60) via the transmission of messages (6) where the actions are defined.

The configuration of the distributed logic is made from the HUB (1), responsible for transmitting in a message (6) the logical rules that a node (60) must process locally. Once the node (60) has been configured, it does not need the intervention of the HUB (60) to carry out the actions.
El diseño de la arquitectura del HUB presenta las siguientes características:The HUB architecture design has the following characteristics:
• Es independiente de la tecnología de comunicaciones. Para cada tecnología de comunicaciones existe un módulo software genérico o controlador que permite recibir y transmitir los mensajes (6) del sistema a través de cualquier tipo de tecnología. • It is independent of communications technology. For each communications technology there is a generic software module or controller that allows receiving and transmitting the messages (6) of the system through any type of technology.
• Es extensible a nuevas tecnologías. Siguiendo el formato del controlador, es posible añadir nuevas tecnologías sin necesidad de cambios en la arquitectura.  • It is extensible to new technologies. Following the format of the controller, it is possible to add new technologies without changing the architecture.
• La información y el procesado de lógica se encuentran separados. Las funciones a realizar mediante la lógica del sistema se define mediante el intercambio de mensajes (6) entre el HUB (1 ) y los nodos (60), de forma totalmente independiente a como es obtenida o transmitida esta información en función de la tecnología.  • The information and logic processing are separated. The functions to be carried out through the system logic are defined by the exchange of messages (6) between the HUB (1) and the nodes (60), completely independent of how this information is obtained or transmitted depending on the technology.
• La ejecución de lógica se lleva a cabo mediante las Interfaces de aplicación (APIs) (2, 3, 4), es decir, la ejecución de las acciones, o lo que es lo mismo, el envío de mensajes (6) hacía los nodos (60) se lleva a cabo a través de aplicaciones que utilizan las Interfaces de aplicación (APIs) (2, 3, 4) definidas para el control del HUB (1 ). • The logic execution is carried out through the Application Interfaces (APIs) (2, 3, 4), that is, the execution of the actions, or what is the same, the sending of messages (6) to the nodes (60) takes carried out through applications that use the Application Interfaces (APIs) (2, 3, 4) defined for the control of the HUB (1).
En la Figura 2 se muestra como se realiza el control de un HUB (1 ) mediante un dispositivo de acceso (32) y un dispositivo de procesado (33) a la base de datos (30) de los nodos (60) asociados al HUB (1 ) y la utilización de las Interfaces de aplicación APIs (2, 3, 4) para la ejecución de los distintos mensajes hacía los nodos (60) a través de una línea de transmisión y recepción (34) precedida de un dispositivo de agregación de datos (35). Figure 2 shows how the control of a HUB (1) is performed by means of an access device (32) and a processing device (33) to the database (30) of the nodes (60) associated to the HUB (1) and the use of API Application Interfaces (2, 3, 4) for the execution of the different messages to the nodes (60) through a transmission and reception line (34) preceded by an aggregation device of data (35).
El sistema (50) comprende tres Interfaces de aplicación APIs (2, 3, 4) que utilizan conexiones TCP (siglas en ingles de "Transmission Control Protocol") para el intercambio de mensajes (6): The system (50) comprises three API application interfaces (2, 3, 4) that use TCP ("Transmission Control Protocol") connections for the exchange of messages (6):
• Una Interface de aplicación (2) para el nodo (60) que permite el envío de mensajes (6) a los nodos que ((60) se encuentran conectados en el HUB (1 ). Acepta conexiones tan sólo de aplicaciones locales. • An Application Interface (2) for the node (60) that allows the sending of messages (6) to the nodes that ((60) are connected in the HUB (1). Accepts connections only from local applications.
• Una Interface de aplicación (3) para los controladores (40, 41 , 42, 43) que permite el control de los distintos controladores (40, 41 , 42, 43) de red de las tecnologías descritas anteriormente. Acepta conexiones tan sólo de aplicaciones locales, y  • An Application Interface (3) for the controllers (40, 41, 42, 43) that allows the control of the different network controllers (40, 41, 42, 43) of the technologies described above. Accept connections only from local applications, and
• Una Interface de aplicación (4) para cada HUB (1 ) que permite la comunicación entre HUBs (1 ) y la recepción de mensajes (6) de otra Interface de aplicación global (5) que es utilizada por las aplicaciones que tienen acceso a la red del sistema (50).  • An Application Interface (4) for each HUB (1) that allows communication between HUBs (1) and the reception of messages (6) from another Global Application Interface (5) that is used by applications that have access to the system network (50).
La conexión de la Interface de aplicación (4) para cada HUB (1 ) es realizada desde el propio HUB (1 ) hacia un servidor central (70) o hasta el controlador de HUBs, en función del rol que tenga cada HUB (1 ) dentro del sistema (50).  The connection of the Application Interface (4) for each HUB (1) is made from the HUB itself (1) to a central server (70) or to the HUB controller, depending on the role of each HUB (1) within the system (50).
En la Figura 3 se muestra como se realiza el control del HUB (1 ) mediante el acceso a la base de datos (BBDD) (30) de los nodos (60) asociados al HUB (1 ) y la utilización de las Interfaces de aplicación (APIs) (2, 3, 4) para la ejecución de los distintos mensajes (6) hacía los nodos (60). Figure 3 shows how the control of the HUB (1) is performed by accessing the database (DB) (30) of the nodes (60) associated to the HUB (1) and using the Application Interfaces (APIs) (2, 3, 4) for execution of the different messages (6) to the nodes (60).
En el nivel de granularidad más pequeño, la red del sistema está formada por los nodos (60), los cuáles agrupan todos los datos en los HUBs (1 ) donde se encuentran asociados. En la arquitectura de la red del sistema (1 ) definida, los distintos datos de los HUBs (1 ) que se encuentran en una misma zona con un mismo dominio son agregados hacia un HUB principal (10) (ver Figura 3). Este HUB principal (10) tiene en su base de datos (30), toda la información del domino del sistema (50) que mantiene, a través de la Interfaz de aplicación de HUB (4), que le permitirá realizar las acciones pertinentes entre los diferentes HUBs (1 ). At the smallest level of granularity, the system network consists of nodes (60), which group all the data in the HUBs (1) where they are associated. In the system network architecture (1) defined, the different data of the HUBs (1) that are in the same area with the same domain are added to a main HUB (10) (see Figure 3). This main HUB (10) has in its database (30), all the information of the system domain (50) that it maintains, through the HUB Application Interface (4), which will allow it to perform the relevant actions between the different HUBs (1).
Del mismo modo, los distintos HUBs principales (10) enviarán los datos agregados hacia el servidor central (70), tal y como muestra la Figura 4. Es el servidor central (70) el que permitirá el acceso a las distintas aplicaciones a través de la Interfaz de aplicación (4), distribuyendo las peticiones de la Interfaz de aplicación (4) hacia los HUBs principales (10) específicos y ofreciendo a las aplicaciones la información del sistema (1 ) almacenada en una base de datos global (31 ), la cual agrega toda la información de las bases de datos (30) distribuidas de cada uno de los HUBs (1 ). Similarly, the different main HUBs (10) will send the aggregated data to the central server (70), as shown in Figure 4. It is the central server (70) that will allow access to the different applications through the Application Interface (4), distributing the requests of the Application Interface (4) to the specific main HUBs (10) and offering the applications the system information (1) stored in a global database (31), which adds all the information of the distributed databases (30) of each of the HUBs (1).
El sistema establece, a través de la Interfaz de aplicación del sistema (5) y de la Interfaz de aplicación del HUB (4) una transmisión de mensajes (6), preferentemente de tipo JSON (JavaScript Object Annotation) para realizar las distintas funciones de acción y configuración de la red del sistema. Cada petición de transmisión de mensajes JSON realizada deberá esperar el mensaje JSON de respuesta con los resultados de la acción o la información solicitada por las aplicaciones. La Figura 5 muestra los distintos flujos de mensajes (6) en función del tipo de mensaje JSON procesado, ya que no siempre resultará en un mensaje (6) directo al nodo (60). The system establishes, through the System Application Interface (5) and the HUB Application Interface (4) a message transmission (6), preferably of JSON type (JavaScript Object Annotation) to perform the various functions of action and configuration of the system network. Each request for transmission of JSON messages made must wait for the response JSON message with the results of the action or the information requested by the applications. Figure 5 shows the different message flows (6) depending on the type of JSON message processed, since it will not always result in a message (6) direct to the node (60).
Cada HUB (1 ) dispone de una base de datos SQL (Structured Query Language), en concreto MySQL, para almacenar toda la información de los nodos (60) controlados por este HUB (1 ). Each HUB (1) has an SQL database (Structured Query Language), specifically MySQL, to store all the information of the nodes (60) controlled by this HUB (1).
