Automatic ship identification monitoring method fusing multiple data sources and supervisory system

Abstract

The invention relates to an automatic ship identification monitoring method fusing multiple data sources and a supervisory system. The method comprises the following steps: (1) performing laser scanning on a ship; (2) triggering a radio frequency identification (RFID) system to read radio frequency tag information of the ship and shoot a video image; (3) establishing a matching relation between a shore-based RFID reader and the ship; (4) acquiring the ship information through laser; (5) judging the data information of the detected ship, and counting the data; (6) performing manual intervention on the measurement result. The system comprises multiple monitoring sites, a data center room communicating with the multiple monitoring sites through a local area network, and a monitoring client and a service client. Three technical data sources from the RFID, the video image and the laser are fused, unique abstract data description is established for actual conditions such as identity, physical size, shipping conditions and cargo transport of the ship in inland waterways, the underway ship is comprehensively and effectively supervised by the channel and maritime affair department in real time, and a metadata support is provided for integrated management.

Description

technical field [0001] The present invention relates to a ship automatic identification monitoring system and method thereof which integrates multiple data sources, specifically a ship automatic identification monitoring method and a monitoring system which integrates three technical data sources from RFID, video image and laser. Background technique [0002] As an ancient way, water transport has attracted more and more attention and attention in recent years due to its advantages of large transport capacity, low energy consumption, and less pollution. How to improve water traffic conditions and reduce the incidence of ship traffic accidents has been highly valued by maritime agencies and port and shipping departments, and many experts and scholars have also conducted a lot of research. At present, in order to improve the safety of ship navigation, relevant departments have strengthened the supervision of ships, and the first problem to be solved is how to monitor the traff...

Problems solved by technology

The existing ship monitoring technology is limited by many factors, and there are still many deficiencies in the application. In most cases, accurate and all-weather automatic ship monitoring cannot be realized. Therefore, new and feasible technologies are urgently needed to solve the problem of ship types, Monitoring issues of ship length, ship width, ship speed, draft, gross tonnage, and actual cargo volume

[0003] Chinese Patent No. ZL 201220683562.7 disclosed a system for monitoring ship traffic in inland waterways on June 26, 2013. It is based on shore-based active scanning detection, using laser measurement as a means and ship feature recognition as a basis. The collected data is analyzed and calculated mathematically to realize uninterrupted monitoring of ship type, ship length, ship width, ship speed, draft, gross tonnage, actual cargo capacity and other data. This technology solves the actual physical properties of the ship , but the identity of the ship cannot be determined

Offshore identification technology can identify the identity of the ship offshore, and then can obtain the registration scale of the ship (including the length, width, tonnage, etc.) of the ship, but it cannot determine the true scale of the ship, which brings great inconvenience to the inspection and management. Unable to guarantee the course of the ship and the safety supervision of the passage, it is easy to lead to the occurrence of unsafe hidden dangers such as inconsistent licenses and overloading
