Ship-shore communication method and system in ship management system

Abstract

The invention discloses a ship-shore communication method and system in a ship management system, wherein the method includes: a ship end sets a first mark field for the first data to be synchronized in a first database, and assigns the first mark field to the first data according to the priority data. The first data in a database is set with a second mark field; the first data with the first mark field is divided according to the second mark field to obtain a plurality of groups, and the first data in each group is encapsulated to obtain the corresponding first data A data packet is stored in a plurality of first message queues; the ship terminal sends the first data packet in the target first message queue to the shore terminal according to the current network type; the shore terminal receives and verifies the first data packet, if If the verification is passed, a reception success message is sent to the ship end, and the first data in the first data packet is stored in the second database. The solution can effectively manage data synchronization and update, and realize reliable communication between ship and shore.

Description

technical field [0001] The invention relates to the field of data communication in a ship management system, in particular to a ship-shore communication method and system in the ship management system. Background technique [0002] figure 1 A schematic diagram of the application scenario of the ship management system is shown, such as figure 1 As shown, data communication is performed between the ship side 101 and the shore side 102 via the public Internet 103 . In the ship management system, because the communication link is extremely unstable and the network bandwidth is seriously insufficient, the data transmission process between the ship and the shore is abnormal, which seriously affects the data synchronization and update between the ship and the shore. Sending and receiving use the public Internet such as satellite communication, mobile communication network (such as 5G network, 4G network, 3G network, etc.), while the internal network (that is, the intranet) is use...

AI Technical Summary

Problems solved by technology

In the ship management system, due to the extremely unstable communication link and the serious shortage of network bandwidth, the data transmission process between the ship and the shore is abnormal, which seriously affects the data synchronization and update between the ship and the shore. Public Internet such as satellite communication and mobile communication network (such as 5G network, 4G network, 3G network, etc.) are used for sending and receiving, while internal network (i.e. intranet) is used inside the shore terminal, which is subject to information security protection constraints. The data transmission between the Internet and the public Internet is not smooth and prone to information security vulnerabilities

Therefore, in the existing technology, there is a lack of reliable data communication between the ship and the shore, and problems such as data loss, data duplication, and limited access are prone to occur during data synchronization.
