Development of Client-Server based Network Centric Remote Data Acquisition Systems

Abstract

A network centric remote data acquisition system was developed by utilizing the available network resources and technologies such as Java applets / applications and sockets. The digitizing hardware was based on an AD7569 chip that contains two ADC channels with conversion time of 2 μs and two DAC channels with settling time of 1 μs both with 8-bit resolution. The system enables the analysis and the displaying of dynamic analog signals that are acquired at a remote location, on a web browser based interface of a local PC.
