Problems solved by technology

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 slow

specific Embodiment 1

[0033] Specific embodiment one. Shore-based system broadcasting service

[0034] The shore-based system broadcasts given information to the surrounding area through the base station; the shore-based system can specify to broadcast information through the ASM channel or VDE channel. The process is as follows:

[0035] The shore-based system sends the information to be sent to the VDES gateway management center through the network through the HTTP interface;

[0036] After receiving the information, the VDES gateway management center processes the information and sends the information to be sent to the base station through the network;

[0037] If the shore-based system specifies the ASM channel to send, the base station broadcasts the corresponding message on the ASM channel;

[0038] If the shore-based system specifies the VDE channel to send, the base station broadcasts the corresponding message on the VDE channel;

[0039] After the shipyard receives the message, it comp...

specific Embodiment 2

[0041] Specific embodiment two. Shore based system addressing service

[0042] The shore-based system sends given information to the designated ship through the base station. The shore-based system can specify to send information through the ASM channel or VDE channel, and the principle of data exchange is as follows: figure 1 . The specific process is as follows:

[0043] The shore-based system sends the information to be sent to the VDES gateway management center through the network through the HTTP interface;

[0044] After receiving the information, the VDES gateway management center processes the information and sends the information to be sent to the base station through the network;

[0045] If the shore-based system specifies the ASM channel to send, the base station will broadcast the corresponding message on the ASM channel;

[0046] If the shore-based system specifies the VDE channel to send, the base station broadcasts the corresponding message on the VDE chan...

specific Embodiment 3

[0052] Specific embodiment three. VDES and external interface communication service

[0053] The client, namely the ship, uses the berth to send service requests to the shore-based system. The service request includes a service list request and a service item request.

[0054] Among them, the service list request realizes that the ship end requests the shore-based system to obtain the local available service list information; the service item request realizes that the ship end requests the shore-based specific services given in the service list. Service requests are made through ASM messages.

[0055] The shore-based system responds after receiving the service request from the ship. It is designated by the shore-based system to send information through ASM channel or VDE channel. The communication between the berth and the onboard ECS server ECS is carried out in TCP mode, in which the berth is the server end, and the onboard ECS server ECS is the client.

[0056] After t...

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 [0003] I...
