Ship trajectory monitoring system based on block chain

Abstract

The invention discloses a ship track monitoring system based on a block chain. The ship track monitoring system comprises a main communication node A0 and n replica communication nodes, the main communication node A0 and the n replica communication nodes form a block chain; the block chain stores AIS information; the replica communication node obtains AIS information from the block chain, and track backtracking query is completed; the invention relates to a ship trajectory monitoring system based on a block chain technology, which mainly solves the problem of accurate backtracking of a channel supervision mechanism on the whole process of a ship moving trajectory, and effectively prevents data missing caused by ship trajectory data tampering and node abnormity. The strong-collisiveness cryptographic algorithm used in the invention ensures the security and confidentiality of the data, the load of all nodes is reduced by using a node marginalization calculation summarization mode, the resource waste is reduced, and hacker attacks can be prevented.

Description

technical field [0001] The invention relates to the field of data encryption secure communication, in particular to a blockchain-based ship track monitoring system. Background technique [0002] Inland waterway shipping is an important channel for water transportation in my country. It has the characteristics of convenience, speed and large transportation volume. my country relies on its unique geographical advantages. The volume is also increasing year by year. According to statistics, the cargo volume in a single month in 2020 has reached 706.59 million tons. Therefore, the safety and smoothness of the waterway has become an important guarantee for water transportation. At present, inland waterways have basically realized digitization, intelligence and networking. Although the construction of digital waterways has brought certain results, due to the complex and harsh environment of the waterway, such as: deep water and rapid currents, frequent evolution of continental beac...

AI Technical Summary

Problems solved by technology

Although the construction of digital waterways has brought certain results, due to the complex and harsh environment of the waterway, such as: deep water and rapid currents, frequent evolution of continental beaches, severe riverbed evolution, unstable communication signals, and many signal blind spots, the ship traffic command system is vulnerable to hackers Intrusion, the above factors lead to the loss or tampering of received AIS data, discontinuous trajectory traceback, and difficulty in obtaining evidence for accidents, etc.

When there are average damage accidents in the controlled river section, such as: falsely reporting the position of the ship and causing the upper and lower ships to enter the trough and collide at the same time, the ship causing the accident collides with the navigation mark and escapes, causing the following ship to yaw, run aground or collide, and the ship damages the shore-based equipment and escapes, etc., if the The signal station in the jurisdiction cannot accurately and continuously trace back the AIS position information of the ship, and the waterway supervision department cannot locate the ship involved in the accident due to insufficient data evidence, which leads to difficulties in the verification of the waterway supervision department, provocative authority, and losses to the national economy

[0003] At present, the ship trajectory backtracking solution for the inland waterway control section only solves the problem of how to store AIS data on a single node, and does not have the trajectory data anti-tampering and disaster recovery capabilities
