Ship-shore connection system-based big data information transmission mode

Abstract

The invention belongs to the technical field of data transmission communication and relates to a ship-shore connection system-based big data information transmission mode. The ship-shore connection system-based big data information transmission mode comprises a ship-side data workstation, a shore-side data workstation, a first NEC data transmission modem, a second NEC data transmission modem, an optical fiber connection carrier and an SSL communication system; ship-shore communication is adopted as a carrier of big data exchange, and the network construction platform technology of the ship-shore communication is mature and convenient, good in compatibility and strong in universality, and can be suitable for various ships, platforms and oil gas terminals; the personalized requirements of customers can be met, the inclusiveness of transmitted data is wide, and the selectivity is high; the later maintenance cost is low, reading can be achieved just by decoding data through a photoelectric conversion module, most importantly, safety is high, interference of severe electricity and electromagnetic waves is avoided; and the data can be stored in real time, and even if connection is cut off in an emergency, the transmitted data cannot be lost.

Description

technical field [0001] The invention relates to the technical field of data transmission and communication, in particular to a large data information transmission method based on a ship-to-shore connection system. Background technique [0002] As a clean energy source, the market demand for LNG has been growing steadily. In LNG engineering ship and platform projects, it is more and more common for the shore side to demand data on the pressure, temperature, density and mooring of natural gas tanks of berthing ships or FSRU (floating storage and regasification units). In order to meet the needs of operation and communication, the application of ship-to-ship and ship-to-shore data transmission is increasing. Ship-to-shore big data exchange has been increasingly included in newbuilding or refit projects as a mandatory requirement by shipowners or ship leasing companies. [0003] The current applications are more based on satellite communication and maritime radio communication...

AI Technical Summary

Problems solved by technology

The cost of satellite communication equipment and later use is relatively high. At the same time, the hardware and software of satellite communication need to be regularly upgraded and maintained, which is very uneconomical

[0005] Although the maintenance cost of radio communication is relatively low, radio communication is relatively susceptible to interference from weather and electromagnetic wave signals, data transmission is unstable, data transmission volume is relatively small, and system reliability is relatively low
