Abstract

The invention discloses a VDES-based maritime service set information data interaction method. The method comprises the steps that S1, a shore-based system sends information to be sent to a VDES gateway management center through a network in an HTTP interface mode; S2, the VDES gateway management center receives and processes the information and then sends the information to be sent to the VDES base station through a network; S3, the VDES base station transmits the information to a VDES slipway, the slipway receives the message and then completes message analysis, and generates a corresponding network transmission packet, and the transmission packet is sent to a shipborne ECS through a network port; S4, the ship-borne ECS receives the data transmitted by the network port and then analyzes the data. According to the invention, data exchange between the shore-based system and the VDES gateway management center, the VDES base station and the VDES slipway is realized; and all data exchange services between ships and between ships and shores can be satisfied.

Description

technical field

[0001] The invention belongs to the technical field of communication, relates to maritime information data exchange, in particular to a VDES-based maritime service set information data exchange method. Background technique

[0002] With the continuous improvement of the demand for data communication on the water in recent years, AIS, which originally aimed to realize the mutual identification of ships and avoid collisions, has gradually assumed the task of ship-to-shore data communication. The increase in the AIS system's communication requirements in the VHF frequency band has caused the AIS system's usable frequency band to be very crowded. Due to the relatively narrow bandwidth, the communication rate is only 9.6 kilobits per second. This transmission speed is roughly equivalent to the transmission speed we used many years ago. Simple voice, short message 2G mobile phone, and the transmission rate is relatively slow. Contents of the invention
