Abstract

This study describes a system for the analysis of the fault diagnosis of marine equipments in inland rivers. Since the normal operation of the marine equipments significantly influences the ship safety, this study develops an efficient fault diagnosis information system for the condition monitoring and fault diagnosis of marine equipments. In this new system, field bus and ship-to-shore communication technologies have been integrated for the fault diagnosis information acquisition. Then the application of network bus, including CAN and RS485, has been employed to connect the fault diagnosis information with Ethernet in the ship. Lastly, for the real time and wireless transmission of the fault information, the Automatic Identification System (AIS) technology has been adopted to provide accurate and reliable fault diagnosis information transmission from ships to onshore diagnosis center. A comprehensive study of the application of proposed fault diagnosis information system has been implemented for remote diagnosis of marine equipments. The analysis results demonstrate that the newly developed fault diagnosis information system can enhance the fault diagnosis precision and hence is competent for the condition monitoring and fault diagnosis of marine equipments in inland rivers.

Highlights

The trouble shooting of the equipment installed in geographically distant locations brings the remote diagnosis technology, which would achieve savings in cost and time for both customers and manufacturers
With the help of computer and communication technology, the vessel field bus acquires the fault diagnosis information and the communication is achieved between the shore-based service center, so as to monitor the operation condition of the vessel device and provide technical service
The fault diagnosis and safety maintenance of the vessel equipments can be realized, which would be of great importance for the vessel to sail safety and reduce the cost

Summary

INTRODUCTION

The trouble shooting of the equipment installed in geographically distant locations brings the remote diagnosis technology, which would achieve savings in cost and time for both customers and manufacturers. The vessels in inland rivers work in an environment of complexity and uncertainty, with the lack of technical support, so the marine equipment condition monitoring and remote fault diagnosis would significantly improve the reliability of the marine equipment (Wang et al, 2004; Ramnath et al, 2011). Taking power equipments for communication speed, perfect reliability and strong example, there are three kinds of methods for fault anti-interference and so on, the CAN bus has already diagnosis, they are oil monitoring, vibration analysis become one of the most popular field bus and the above and parameter analysis and each method involves the advantages make it suitable for corresponding analysis of various physical quantities to interconnection of small and medium-scale industrial be collected, judged, processed and displayed. Respectively for a specific purpose and various data There are two modes in current version: standard mode interfaces or methods are formed, within which the and extended mode (Cavalieri et al, 1996)
