基于近实时海洋遥感数据的渔场预报系统设计与实现

Design and implementation of fishing ground forecasting system based on near real-time remote sensing data

针对国内渔业企业对于渔场预报系统的需要,设计和开发基于近实时海洋遥感数据的渔场预报系统。系统分为陆地数据服务和渔情预报软件两个模块,其中:陆地服务模块负责收集全球近实时海洋环境数据,并提供环境数据下载服务;渔情预报软件可以从陆地服务器下载海洋环境数据,并通过这些数据,使用栖息地适应性指数模型进行渔场预报,为渔业企业和作业渔船的捕捞决策提供辅助。两个模块之间以国际海事卫星船队宽带系统作为数据传输手段。前期的远洋渔船应用试验表明,该系统能稳定下载海洋环境数据并实现渔场预报,预报结果作为捕捞决策的重要辅助信息,可为渔业生产者选择作业地点提供很好的参考。

To fulfill the needs of fishing ground forecasting system of domestic fishery companies, a fishing ground forecasting system is developed based on near real-time remote sensing data. The system has two modules, the land data service module and the fishing ground forecasting software module. The land service module is responsible for collecting the global near real-time marine environment data and providing the environmental data downloading service. The fishing ground forecasting software module can download the marine environment data from the land server and use the data to forecast the fishing ground using the habitat suitability index model. The system uses the International Maritime Satellite broadband services as data transmission channel. Former application tests of deep-sea fishing vessels indicated that the system can download the environmental data stably and calculate the potential fishing ground, which is important auxiliary information for fishing decision and can be used as a reference for fishing location selection.
