RIASSUNTO

T121 are more than 50 thousands fishing vessels that have installed BEIDOU satellite navigation and positioning system in coastal waters of China and this system can send back the fishing vessels ‘position, speed and direction with temporal resolution of 3 min and spatial resolution of 10m. The server have to receive more than millions of records every day. The key to provide an efficient service is trying to make a quick search and get data records instantly. The data management and search work of distributed Beidou system is through the application server to process data and the processed data will be saved into the file server dispersedly by management sever according to the allocation, also the saving position will be recorded. The web server provides access service for external network, for it will send external access requests to application server and next the application server will get dispersive file data through manage sever, finally the data will be processed based on their access requests by application server and sent back to web server. So the data described can be divided into two parts, one part is the basic data and the other is the service data. When the system is ongoing, the data can be read into the memory and the system can operate date file directly by using the memory buffer, so that to implement the spatial and temporal distribution searching works of the fishing vessels accurately and visually.
