A Design of Marine Propulsion Shaft Power Telemetry System

Abstract

In order to achieve the marine shaft power’s dynamic telemetry, on the basis of the analysis of shaft power measurement’s fundamental principles, from both hardware and software, the telemetry system has designed basing on magnetic sensing phase difference type. The system can real-time acquire and analysis process to the torque and rotational speed signal, and online real-time calculate shaft power. It can meet needs of the ship shaft power telemetry and shaft conditions in real-time monitoring.
