Application of Data Acquisition System for Superconducting Quantum Interface Devices (SQUID) at Remote Location [p. 967-970]

Abstract

Together with technological developments related to the specific area, the scope of remote data acquisition systems has become widened. The usages of these kinds of systems prevent waste of time and labor. Therefore, in this work, the introduction and design of a data acquisition system that can sense and send the output of Superconducting Quantum Interface Devices (SQUID) to main lab via wireless with GPRS is aimed to be provided. The system of this design uses FPGA and MCU together within the processes of collecting, packing and sending data. In this design, XILINX Spartan 3AN is used as a FPGA, ST Microelectronics ARM Cortex-M4 used as a MCU. The main purpose of FPGA is collecting analog data with using ADC and packing them in order. On the other hand, the main purpose of MCU is to send packed data through the GPRS. The processing load of MCU is decreased by using FSMC (Flexible static memory controller) of it while getting data from FPGA; also with parallel connection data transfer rate is increased. Also by using FSMC, first time 200Hz data collecting will actualized through the remote data acquisition systems based on GPRS.
