Research Of Database Synchronization Technology Of Ship Monitoring System

In recent years, with Distributed Control System (DCS) in the ship monitoring's widespread application,so there are a lot of decentralized control module in the ship monitoring system, including the host and its auxiliary systems, damage control system, power plants and related data systems and navigation systems,but the ship monitoring system also calls for these decentralized control module to carry on the centralism surveillance, the operation and the management. On the one hand, these scattered data acquisition control module to transmit real-time monitoring system to focus on the central monitoring server in order to ship all equipment operators informed of changes in real-time data; On the other hand, the ship made by the operator command to operate, but also should be notified in a timely manner at the bottom of each sub-station.which requires all data collected by these monitoring module in real time and accurately synchronization to the monitoring system's central server, so the research of application of database synchronization technology on ship monitoring system has a strong theoretical and practical value.This paper has discussed the ship monitoring system's development process and trends thoroughly, pointing out the need of database synchronization in the ship monitoring system; Then detail the development Status of the database synchronization(replication) technology, discuss database replication technology based on SQL Server 2000; Then in-depth study the consists of ship monitoring system , using SQL Server 2000 to create the database of ship monitoring system, using Visual C + + 6.0 to design man-machine interface of ship monitoring system, through the ODBC API technology to achieve access to the database; Finally in-depth study the application of database replication technology based on SQL Server 2000 in the ship monitoring system to update data synchronization, introduced in detail the process of its implementation and analysis of the results concluded that: Applying database replication technology in the ship monitoring system to achieve data synchronization update is feasible.
