Marine engine state monitoring system using distributed precedence queue mechanism in CAN networks

Abstract

This paper proposes a marine engine state monitoring system using distributed precedence queue mechanism which collects the state of bearings, temperature and pressure of engine through the CAN network. The CAN is developed by Bosch Corp. in the early 1980'. The data from various sensors attached in the marine engine are converted to digital by the analog to digital converter and formatted to fit the CAN protocol at the CAN module. All the CAN modules are connected to the SPU module for the efficient communication and processing. This design reduces the cost for wiring and improves the data transmission reliability by recognizing the sensor errors and data transmission errors. The distributed precedence queue mechanism is developed for the performance improvement of the marine engine system, which is demonstrated through the experiments. © 2010 Springer-Verlag.
