Abstract

A frame structure configuration method for VDES data transmission, used for data transmission between a shore station and a management center, the application data domain of the frame structure includes business data and configuration management data, and the business data includes automatic identification system business data, specific Application message business data, VHF data exchange business data, wherein VHF data exchange business data includes but not limited to certificate files, electronic chart data. According to the carrier frequency in the configuration data, the electronic chart data in the business data is subpackaged, and then the management center sends the subcontracted electronic chart data to the shore station. Adopt dynamic data management and transmission methods, greatly improve the operating efficiency and flexibility of the system, and improve the management ability of the system's multi-shore stations.

Description

technical field [0001] The invention relates to a frame structure configuration method, a transmission device and a system for VDES data transmission, and belongs to the technical field of VDES shore station management. Background technique [0002] VDES (VHF Date Exchange System, VHF Data Exchange System) system is an important supporting technology for IMO (International Maritime Organization) to implement the E-navigation strategy. "On-demand service" capability information interaction carrier. [0003] The narrow VDES system consists of ship station equipment and shore station equipment. The ship station equipment and the shore station equipment analyze the standard message through the self-organizing network to realize the communication between the equipment. The goal of the VDES system is to better let the management personnel on the shore understand the status of the ship, and provide the management personnel with more convenient and richer means of ship safety mana...
