Embodiment 1

[0043] figure 1 An exemplary block diagram for the implementation of the method of the present invention. Processing flow chart such as figure 2 As shown, it includes positioning of fishing boats and receiving and processing of feedback information from fishing boats, extraction and transformation of surrounding environmental information of boats, forecasting of fishing grounds around boats, coding of forecast information and related environmental information, sending fishery service information to fishing boats, etc. Here is an L2-level product of MODIS (Moderate Resolution Imaging Spectrometer) data—the image size is 2160×4320 pixels, including sea surface temperature and chlorophyll concentration products, which already have geocoding information. At the same time, the corresponding ocean current data is selected. image 3 Displays environmental information such as sea surface temperature, chlorophyll concentration, and ocean current vector.

Abstract

The invention relates to a position-based marine fishery information serving method. Particularly, by utilizing positioning and communication functions of a Beidou navigation satellite, position information, production data and actually measured environment data of a fishing boat are acquired, data of fishing area grids around a position of the fishing boat and the data conversion is carried out to obtain environment data in a vector form; a formed fishing ground forecasting model is subjected to online training optimization by utilizing the acquired production data and actually measured environment data of the fishing boat so as to improve the accuracy and the generalization ability; a selection region around the fishing boat is subjected to fishing ground forecasting by utilizing the forecasting model to obtain information of the fishing area grids and the fishing ground probability; obtained environment parameter information of the fishing ground probability and the fishing area grids are coded and is sent to the fishing boat as fishery service information for the single boat. According to the invention, a position-based customized high-accuracy service is implemented; the data communication quantity of the position-based marine fishery information serving method is much lower than that of a conventional method; the position-based marine fishery information serving method has low communication cost, is easy to popularize and apply and can be used for providing the low-cost customized high-accuracy fishery information service which is based on the position and the data grids and faces the single boat for the fishery production department.

Description

technical field [0001] The invention belongs to the technical field of fishery information, and in particular relates to a location-based marine fishery information service method. Background technique [0002] Marine fishery is an important component industry of the marine economy. The development of marine fishery resources is a production activity that relies on marine space. The marine space environment and fishery resources are the necessary platforms and carriers for these industrial activities. In marine fishery production and management, marine fishery information services have become an important guarantee for the realization of marine fishery production and management planning goals. Relevant research and applications have been carried out at home and abroad to provide information services for marine fisheries using high-tech such as computer network communications and satellite applications. Most of them focus on using marine environmental information obtained by ...
