Design and Development of FPGA Based Data Acquisition System for Process Automation

This paper presents a novel approach to the design of data acquisition system for process applications. The core heart of the proposed system is Field Programmable Gate Array (FPGA) which is configured and programmed to acquire a maximum of 16 MB real time data. For the real time validation of the designed system, a process plant with three parameters i.e. pressure, temperature and level is considered. Real time data from the process is acquired using suitable temperature, pressure and level sensors. Signal conditioners are designed for each sensor and are tested in real time. Designed FPGA based data acquisition system along with corresponding signal conditioners is validated in real-time by running the process and comparing the same with the corresponding references. The data acquired in real time compares well with the references.
