Design Improvements Of Wirelesshart Enabled Field Device, Yuxuan Zeng

Graduate Theses - Electrical and Computer Engineering

WirelessHART, as an improvement of HART (Highway Addressable Remote Transducer), provides a simple, reliable, and cost-effective method to deliver information without the trouble of wiring in the field. WirelessHART is being used more and more in field devices. Several years ago, Endress + Hauser (U.S.) Automation Instrumentation Inc. designed a WirelessHART solution by attaching a wireless adapter to a field device. The goal of this thesis is to improve the WirelessHART solution of Endress + Hauser to make it less expensive, smaller, and less power-consuming. The work is done in two parts. The first part is to redesign an I/O …
