Diseño de una arquitectura basada en FPGA para la emulación de sistemas de adquisición de consumo eléctrico en redes de energía

En este trabajo se realiza el diseño e implementación de una arquitectura SoC (System-on-Chip) para un emulador de un contador inteligente para la experimentación con técnicas NILM, así como el sistema de adquisición de datos que recoge la información enviada por el emulador. El sistema se implementa en la Zybo z7-20, con un dispositivo SoC de la familia Zynq 7000 de Xilinx, Inc; para tanto el envío como la recepción de datos se utilizan dos conversores con interfaz Pmod conectados entre sí. En el procesador se cargarán inicialmente las bases de datos que utilizará el emulador y se enviarán a un terminal una vez pasen por todo el sistema para el análisis de los resultados; en la FPGA se implementan tanto los drivers de los conversores como el controlador que los gestiona.This work involves the design and implementation of a SoC (System-on-Chip) architecture for a smart meter emulator for experimentation with NILM techniques, as well as the data acquisition system that collects the information sent by the emulator.

Definition of a FPGA-based SoC architecture for PRBS transmission in optical spectroscopy

Optical spectroscopy is a well-known tool typically employed for characterizing the properties of materials by analyzing their iteration with light. One of the most spread techniques is the dual comb spectroscopy, since it accomplishes ultra-high resolution, and high sensitivity measurements with a relatively simple platform including a single, relatively narrowband photodetector. The employed optical dual comb can be implemented through electro-optical (EO) modulation driven by pseudo-ransom binary sequences (PRBS) at high data rates, commonly in the range of tens of Gbps. For that purpose, the runtime generation and transmission of adaptive PRBS is still an open challenge, often involving expensive and not flexible high-speed digital systems, with a few commercially available solutions that sometimes do not match the application requirements efficiently. In this context, this work describes the definition and implementation of a System-on-Chip (SoC) architecture, based on a FPGA device, capable of generating and transmitting two PRBS for a dual comb, at a data rate up to 5 Gbps. The architecture can be configured and its operation modified in run time, thanks to the general-purpose processor involved, in charge of managing an Ethernet link to receive new PRBS to be transmitted or set up certain parameters. The proposed design has been validated experimentally on a dual comb spectroscopy measurement, where the absorption of a hydrogen cyanide (HCN) gas cell has been successfully characterized.Agencia Estatal de InvestigaciónMinisterio de Ciencia e Innovació
