Abstract

This paper describes a new digital wireless data acquisition system that can be used to measure electromagnetic interference (EMI) in power stations or other similar harsh environments. It comprises of a Remote Acquisition Unit (RAU), a Wireless Data Communication Network (WDCN) and a PC-based Control Platform As a front end of the fleld-distributed-data-acquisition system, RAU captures, digitizes and stores the EMI signals in its memory and sends the information to the PC using the Wireless Data Communication Network. The WDCN acts as a bi-directional data communication link between the RAU & the Control platform. It is based on Bluetooth technology and has a point-to-multipoint topology. The RAU serves as the acquisition function of a Digital Storage Oscilloscope (DSO) while the Control Platform carries out the display & control function of a DSO. The whole system, as such, may be regarded as a 'Computerised Wireless Oscilloscope'.
