Abstract

This paper describes a new digital wireless data acquisition system that can be used to measure electro-magnetic 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. Using digital technology, the system transmits a signal (transient or steady state) of short duration & wide band through a narrowband channel over a longer duration. The RAU captures and stores the EMI signals and sends the information to the Control Platform at a convenient time, using the Wireless Data Communication Network The Wireless Data Communication Network 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.'
