Web Service-based Status Monitoring And Fault Diagnosis System

Marine environment monitoring system provides necessary basic information and scientific foundation for marine developing, environment protecting, project designing and working safeguard of the marine, making the ocean developing regular and continuable. However, safeguard links of the monitoring system itself were neglected, including computer software resource safeguard, computer network expedite safeguard, veracity safeguard in data transmitting, completeness safeguard and so on.All the running phases of the Ocean monitoring system are analyzed in the thesis. For all the problems of every phase, referring to the actual problems fishery bureau in Fujian province, a feasible scheme is proposed and a condition monitoring system based on Web Service is designed. Software of the condition monitoring system is realized, which can monitor every phase of the integrated Ocean monitoring system, including running condition of the sensors, the computers collecting and managing the data, the network transmitting information, the necessary software and their condition. The condition monitoring system can live up to omnidirectional monitoring, detection problems and alarm in time, and provide solved ideas. Finally, the running condition of the system is gave our using the simulation tests.The main contributions of the thesis are list below:(1) The condition monitoring and malfunction safeguard in mechanism are amplified on software and data layer, every layer of the marine environment system can be monitored.(2) The condition monitoring and malfunction diagnosis frame working for the marine environment system is build. Adopting layered configuration in the frame, the system is divided into four layers, which are data layer, service layer, interface layer and application layer. Every layer can provide different service. The frame can apply in other systems for their condition monitoring and malfunction diagnosis.(3) The concept of service chain is introduced to use in the condition monitoring system, providing clews and foundations in the process of malfunction tracing.
