Abstract

The invention relates to a transmission system which transmits a command to an appointed ship end from a shore end by a satellite. The system comprises a satellite communication device, a shore end device and a ship end device; the satellite communication device comprises a satellite, a shore end satellite communication terminal and a ship end satellite communication terminal; the shore end device consists of a control center and a plurality of terminals connected with the control center by a local area network; wherein, the control center is connected with the communication terminal of the shore end satellite by a land network; the ship end device which comprises a communication controller that is connected with the communication terminal of the ship end satellite and used for analyzing the communication protocol of the received command. An independent communication channel is set by the system, so as to give out the command from the land and then receive the command and execute the command by the communication terminal of the ship end satellite. Compared with the existing Polling technology of transmitting the command on a public channel, the independent command transmission channel is built between the independent networks of the ship and the shore for transmitting the command to the ship end in the mode of point to point, thus solving the problem of unstable transmitting of the command.

Description

technical field

[0001] The invention relates to a command transmission system between ships and shores, in particular to a transmission system in which the command is sent from the shore to a designated ship via satellite. Background technique

[0002] How to realize the effective monitoring of ships sailing around the world has always been a problem that plagues the shipping industry. The key to effective monitoring is that the shore end needs to send instructions directly to the ship end, and the ship end can receive the order stably and quickly.

[0003] With the continuous improvement of IT technology and maritime satellite communication means, the global shipping industry and related software developers are trying to solve this problem. No real breakthrough.

[0004] At present, the ship monitoring technology scheme commonly used in the industry is to use the Inmarsat-C system of the International Maritime Satellite Organization (Inmarsat) to retrieve ship information...
