The Design Of Dredger's Equipment Remote Monitor And Diagnosis System

The condition monitoring and fault diagnosis of mechanical equipments came from the west in 1960. And it was rapidly developed between 1980 and 1990. When its technology and ways of analyses were consummated and improved continuously. It was applied to space flight and some large military equipment at first. Now it is applied to public establishments slowly. But it is never reported in China that the long-distance diagnosis system for dredger is reported. So it is important to make interrelated research.The requirement of dredger's mechanical and electrical equipments' is more and more high because of the continuing consummation of dredger's capability and continuing improving of automation of operation and construction. But the technology and management at present are not satisfied with the requirement of dredger's technical management. With the development of science and technology, the distance diagnosis can come into practice with the necessary technical base of the continuing development of technology of computer, web communication and failure diagnosis. Under the condition of applied technology based on internet combined with intellective computational ways and traditional marine condition monitoring, we can construct a new failure diagnosis system (to develop a distance condition monitoring and failure diagnosis system for main mechanic equipments) in dredger. It can offer timely credible technical guidance and steps to dredging technician. It is satisfied with the need of dredging security, equipments' condition monitoring and failure diagnosis, maintenance decision of the shipping and its base. So it can improve the equipments' using efficiency and management level.This paper discusses the native and foreign development in this field firstly. Then the configure of the researched object and the need of monitoring and failure diagnosis are showed. Thirdly, the systemic failure is analyzed. Fourthly, the functional structure of mechanical equipments' monitoring and diagnosis is designed. Lastly, the structure and systemic designing of the distance monitoring and diagnosis system are discussed.The research result in this article will help improving the dredger's equipment management level, the marine ship using rate, the efficiency and benefit of marine work.
