Problems solved by technology

[0003] Space-borne VDE satellites usually use low-orbit satellites, which run fast and have a short overhead time. According to the space-borne communication protocol stipulated by VDES, ships often lose during data transmission, resulting in high communication failure rates and low channel utilization. Therefore, it is necessary to design a satellite VDE channel resource management system

Abstract

The invention provides a satellite VDE channel resource management system, which comprises a resource statistics unit, a ship list management unit, a communication queue management unit and a resource distribution unit, and is characterized in that the resource statistics unit is used for monitoring shore station messages, analyzing whether satellites in a current sea area can use ground VDE channels in an expanded manner, and performing statistics on satellite VDE available resources; the ship list management unit is used for establishing a ship list and maintaining ship attributes by monitoring ship AIS information, including predicting a ship communication period and predicting ship signal quality changes; the communication queue management unit is used for maintaining a satellite-based VDE transmitting queue and a ship VDE resource request queue; and the resource allocation unit is used for reasonably arranging resource use in a cyclic allocation mode according to the channels provided by the resource statistics unit, the ship list management unit and the communication queue management unit. According to the technical scheme of the invention, reasonable management of satellite VDE channel resources is realized, and the communication success rate and the channel utilization rate can be obviously improved.

Description

technical field [0001] The present invention relates to the technical field of VHF data exchange system, in particular to a satellite VDE channel resource management system. Background technique [0002] VDES (VHF Data Exchange System, VHF Data Exchange System) is an enhanced and upgraded version of the ship's automatic identification system (AIS) in the field of maritime mobile services. It integrates the existing AIS system and adds special application messages ( ASM) and broadband very high frequency data exchange (VDE) functions can effectively relieve the pressure of existing AIS data communication and meet the needs of all data exchange services between ship-to-ship, ship-to-shore, ship-to-satellite, and shore-to-satellite , belonging to the third generation maritime communication system. [0003] Space-borne VDE satellites usually use low-orbit satellites, which run fast and have a short overhead time. According to the space-borne communication protocol stipulated by...
