Centralized Monitoring Using Database Replication

With the development of monitoring technology, the former scattered monitoring system cannot be suitable for the control of ship. Meanwhile, with the need of overall ship informatization, the problem of integrated monitoring system of overall ship appears, so establishing the ship integrated monitoring system will be a significant field.In this paper, the problem of second exploitation in ship integrated monitoring is solved by utilizing database replication system. Firstly, each monitoring module in ship monitoring system is studied, on which the proposition of technology of database replication is based and the detailed method is proposed. Then the theory and method of database replication technology is deeply developed in this paper, and the method of exploitation----SQL-DMO is studied.,At the same time, the database replication technology in integrated monitoring system is studied, and the detailed proposition of this method and configuration is carried out. Finally, the method proposed by us is to use to develop ship integrated monitoring system.Meanwhile, the important problem of ship integrated monitoring----the optimized of characteristic of real time data transmitting is well developed .The work has been well done as follows: propose the method of constructing integrated monitoring system based on applied database replication technology ,deeply study the database replication technology and proposition,the method and step of applied database replication technology in ship integrated monitoring system,propose method for the real time data transmitting problem in ship integrated monitoring.
