Ship-shore data communication system based on 3G wireless network

Abstract

The invention discloses a ship-shore data communication system based on 3G wireless network, which comprises at least one ship end server, a communication control device and a shore end server, wherein the ship end server is connected with the shore end server through the communication control device in a wireless mode. A video acquisition module at the ship end acquires video data; the video data is subjected to analog-to-digital conversion, analysis and processing; the video data is subjected to coded compression and storage according to the analysis and processing result, and transmitted to the shore end by using the communication control device through the 3G wireless network; and a video decoding and play module of the shore end server decodes and plays the video data, thereby implementing real-time transmission of video data. The invention solves the bottleneck of small data transmission bandwidth between the ship and the shore by using the 3G wireless transmission technology, implements the intelligent monitoring of the ship end by using the digital video processing technology, and implements intellectualized management on monitoring, thereby enhancing the work efficiency and greatly lowering the operating cost of the monitoring system.

Description

technical field [0001] The invention relates to the technical field of ship-shore communication, in particular to a ship-shore data communication system based on a 3G wireless network. Background technique [0002] In recent years, with the rapid development of computer technology, information technology, network technology and logistics technology, the maritime industry has made great progress in the use of the Internet. Such as electronic document business system, transportation database system (such as container tracking), customer and pallet management and other systems came into being, which greatly changed the development space of the shipping industry in logistics. As the ship itself, various supporting ship management systems, global satellite positioning systems and maritime satellite communication systems have deeper applications with the development of Internet communication technology, and ships are no longer an "information island". , but can communicate with a...

Problems solved by technology

[0008] 2. The confidentiality of data in the communication process can be solved by means of encryption, but this will bring a corresponding increase in operational difficulty, such as encryption and decryption tools and their process time costs, thus increasing the cost of entry into the implementation

[0011] At present, many well-known companies and enterprises, such as: SONY, Panasonic, SANYO, etc., have begun to use 3G wireless communication technology, but its application in mobile is limited to vehicle video surveillance, mobile phone video, etc.
