Abstract

A frame structure configuration method for VDES data transmission is used for data transmission between a coast station and a management center. An application data field of a frame structure includesservice data and configuration management data, the service data includes automatic identification system service data, specific application message service data, and VHF data exchange service data,and the VHF data exchange service data includes but is not limited to a certificate file and electronic chart data. According to a carrier frequency in the configuration data, the electronic chart data in the service data is subcontracted, and then the management center sends the subcontracted electronic chart data to the coast station. Dynamic data management and transmission are used, so that operating efficiency and flexibility of a system are greatly improved, and a capability of managing multi-station stations of the system is improved.

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...
