Marine gearboxes pose special challenges to a condition monitoring system. The installation of sensors cause an effort of cabling accompanied by inaccessibility in the hull of the ship. A wireless sensor network, consisting of several energy-autonomous sensor nodes, enables the integration of an online condition monitoring system without cabling effort. The sensor nodes record characteristic measurement data, send them actively to a receiving unit and harvest energy from the environment for electrical supply. The sensor node uses a thermoelectric generator that allows measurement intervals of less than 20 minutes. The data transmission was realized using the ZigBee technology. By evaluating the envelope spectrum of the measured vibration data, an artificial bearing damage could be identified.
講演者の経歴 (Sebastian Schirrmacher)
M. Eng. Sebastian Schirrmacher, studied mechanical engineering at the technical college in Hannover with specialization in production engineering in a dual study program at Continental AG. He gained a master degree in the study program "value-added management in mechanical engineering" in combination with a part-time employment as a project engineer at ContiTech AG. Since 2013 Sebastian Schirrmacher is employed as project engineer at IPH in the field of production automation. He was responsible for the research project entitled "Application of wireless technology for economic monitoring of maritime gearboxes", funded by Bundesministerium für Wirtschaft und Technologie (grant/award number: 03SX350A).
