UDP Based Wireless Telemetry Network and Data Acquisition System for Rotary Application

Abstract

This paper presents an open system architecture with wireless network centric telemetry and data acquisition over UDP/IP. This networked solution was designed and developed for iron bird and helicopter rotor applications which present a significant challenge for data acquisition and telemetry. Traditionally slip rings were used for data transfer however these result in issues with low bandwidth, electrical noise, installation complexity, and high maintenance costs. This paper describes a networked system using standardized technologies and protocols that was used for data acquisition and recording of parameters such as vibration, strain, and video on DAQ installed on the rotating part. The acquired data was transmitted in real-time via the network-centric wireless telemetry link which was synchronized with a ground-based DAQ used for real time processing of the rotor data.
