    Abstract:
      Objectives  In recent years, unmanned surface vehicles(USVs) have developed rapidly and will have wide application prospect. Hence it becomes quite urgent to deal with the massive information management problem on long-endurance USVs.
      Methods  According to the characteristics of six types of data in USVs' electronic information system, the topology of USV information management system based on time-series database and the data flow model are proposed, and a set of performance test methods for USV information management system are designed.
      Results  The test shows that the USV information management system is able to meet the information management needs of USVs' operation. Compared with the traditional relational database, the compression performance of the system is improved by about 10%. The retrieval performance and aggregation analysis capability are excellent, and the system is high universal applicability.
      Conclusions  This system is an excellent solution to the problems in information storage and communication transmission on long-endurance USV.
