Abstract

Historical database is a key technology in the field of ship platform monitoring, which is widely used in ship platform monitoring system. It is of great significance for the development of ship platform monitoring technology to establish a historical database system with easy expansion, good openness, high access efficiency and standardized data model. Aiming at the application requirements of data acquisition and process control in real-time monitoring system, this paper puts forward a design idea of historical database system, designs the overall structure of historical database system, and analyzes and designs some important working mechanisms, such as historical data storage mechanism, historical data query mechanism, historical database concurrency control mechanism, historical data synchronization mechanism, etc. The historical database system implemented by this scheme has been running stably in a certain type of ship platform monitoring system, and the practice has proved that it has good storage and query efficiency.
