Abstract

The invention relates to a marine VMS data transmission optimization method based on edge calculation. The traditional marine VMS adopts a centralized operation mode; all visual display and mode mining of fishing boat data are completed in a monitoring center, but marine communication resources are insufficient, data collected by fishing boat terminal equipment cannot be fully transmitted to a shore monitoring center, and the requirement for high real-time performance cannot be met due to communication delay. According to the invention, an edge calculation mode is applied to the marine VMS, and a unified and perfect self-adaptive track transmission strategy is established in a fishing boat and a monitoring center by utilizing the calculation capability of edge nodes. Redundant data are reduced through an LDR algorithm and an SQUISH algorithm, and the number of times of satellite communication is reduced. The reliability of data transmission is ensured through a packet loss feedback mechanism and an error verification strategy.

Description

technical field [0001] The invention applies the edge computing mode to the marine VMS (fishing vessel monitoring system), and optimizes the data transmission of the fishing vessel on this basis. Background technique [0002] Marine VMS is a comprehensive fishing vessel monitoring system that combines global positioning and navigation technology, satellite communication technology, computer technology and geographic information technology. It is mainly divided into two parts: ground monitoring center and shipboard terminal equipment. Among them, the main function of the monitoring center is to provide low-cost flexible computing and storage services. It can receive fishing boat information transmitted by ship-borne terminal equipment through shore-based or satellite and visualize it based on GIS (Geographic Information System), so as to facilitate relevant departments. Supervision of fishing vessels. The monitoring center is designed to provide central control and is mainly...
