Design And Implementation Of The Visualized Command-aided System For Controlled Waterway

To ensure navigation safety, ships must be commanded by signal station, becausecontrolled waterway is fast-flowing and narrow and ships can not watch each other inthe upstream of the Yangtze River. With the development of shipping enterprise in theupper and middle reaches of the Yangtze River, vessels are tending to huge-size,high-speed and intensive, the security capacity of channel is faced with higherrequirements.The command method that the operator can obtain the requisiteinformation about vessels with telescope and VHF was unable to fulfill therequirement of intensive ships, and reduced traffic efficiency and safe capability ofcontrolled waterway.According to requirement and background of the command in Shenbeizuicontrolled area, with the help of Luzhou Navigation Bureau and ChongqingNavigation Bureau, to reduce the work stress of working staffs, improve the commandefficiency and level and promote the digital waterway and the intelligent construction,the visualized command-aided system and method are studied using AIS, GIS andmachine vision in this paper.The main work of the thesis and achievement are summed up as follows:Firstly, based on current situation and business content of the command forShenbeizui signal station, the demands of the visualized command-aided system wasstudied and discussed.Secondly, according to the actual needs of vessels command, the hardwarearchitecture and hardware architecture and functions of the visualized command-aidedsystem were designed.Thirdly, combining with characteristics of controlled waterway, a method ofdetermining the position and course of vehicles based on regional waterway was putforward, and the functions of system were implemented using VC++.Finally, the main equipments were selected based on the project, and the systemwas applied in field.The spot test shows that the system can real-time monitoring the information ofvessels on the sailing initiatively, offer a lot of correct information, such as positionand state of ship, for the operator, and the influence of the false location and bad weather can be reduced for accuracy and efficiency of the command effectively, andcontributes to digitalization and informatization of controlled waterway signal station.
