Study on remote fault diagnosis system using multi monitoring methods on dredger

Power machinery and key equipments are regarded as the monitoring objects. Remote fault diagnosis system based Web is proposed using multi monitoring methods in dredger, which gives a comprehensive consideration of monitoring technology about performance parameters, lubricant oil, vibration and instantaneous speed. The modern ship maintenance management mode of ¿two modes, three levels and four methods¿ is established and used in the selected dredgers of Changjiang Waterway Bureau. Monitoring subsystem on ship, diagnostic subsystem in lab and maintenance decision subsystem in dredgers maintenance management center are designed and realized using computer technology and data fusion technology. Remote fault diagnosis system has been realized using wireless communication technology between the dredger and the technology center. The system to be used on the dredgers has proved to be effective.
