The Network Information For Marine Propulsion Power Plant Condition Monitoring

The marine propulsion power plant is an important constituent of ship. It is the crucial work to maintain the technical condition of marine propulsion power plant condition monitoring and shafting well. Following with the continual increase of the large scale, the automation, the speediness and the digital of the marine power, the difficulty of failure diagnosis and maintenance enlarged everyday. The ships what under sail on the oceans of all parts of the worlds want to obtain the powerful technical support from land or the failure diagnosis and the maintenance center more and more. Along with the swift development of the Internet technology and the mature application of the failure diagnosis technology, it is the important content of marine engine research field and the one of pursued goal to grasp the running status of marine propulsion power plant promptly, accurately and dynamically and to forecast and diagnose the existent and potential failure with the network technology.This article takes it as the main core that establishes a network information platform of marine propulsion power plant intelligence supervisory system. At first it convenes some essential technology bases about the information platform, including the oil monitoring technology of marine propulsion power plant failure diagnosis method, ships shafting centering and computer network information technology. At the basic of mastering the oil monitoring expert system of marine engine develop by the center, the article unifies the plan of the network information platform of marine propulsion power plant intelligence supervisory system, and analyses some sorts of the main technologies, for example: the network technology, the ASP technology, the IIS technology and the network data bank technology and so on.The author selected Access as the backstage database and ASP as the onstage development instruments, and then realized the establishment and performance of the network information platform of the marine propulsion power plant intelligence supervisory system with the present condition and concrete actual situation. Above this foundation, this article has carried on the analysis to the system security, and hasselected the ways to meet the platform and the campus net, finally realized the movement and the test of the information platform.The network information platform of the marine propulsion power plant intelligence supervisory system which is established by the article is the gateway website of oil analysis center in Dalian Maritime University. It offers an information platform for engine long-distance monitoring and intelligent diagnosis. Meanwhile it has the certain meaning for promoting the level of marine engine condition monitoring technical research and enhancing the further cooperation and communication with outside.
