A Reconfigurable On-Chip Multichannel Data Acquisition and Processing (DAQP) System with Online Monitoring Using Network Control Module 

Abstract

The data acquisition and processing architecture covers the most demanding applications in continuous patient monitoring for chronic diseases in medical field and also measuring the signals from industrial plants. The multichannel data acquisition is essential for acquiring and monitoring the various biomedical signals from biomedical sensors or signals from industrial sensors. The problem is that the data storage, hardware size and remote monitoring of the sensed signal/data, so the multichannel data obtained is processed at runtime and stored in an external storage for future reference and remote monitoring of the system is done using Ethernet/Wi-Fi supportive network control module. The method of implementing the proposed design is the system on-chip via field programmable gate array (SoC-FPGA) to reduce the hardware size and for memory size. The Soc-FPGA attains high resolution and real time processing of data acquisition and signal processing. A four channel data acquisition and processing (DAQP) was designed, developed using the Lab VIEW graphical programming. NI DAQ and NI FPGA module is used to test and implement the design for real time. The module was designed in order to provide high accuracy, storage and portability.
