Chen Chen · Navigation of China · 2010
It is the foundation of Yangtze intelligent maritime management to collect real-time and accurate river traffic flow data.Based on the demand analysis of data collecting system for the Yangtze River traffic flow,a frame of multi-source information fusion system is designed,of which the information collection layer consists of IC card subsystem,GPS subsystem,CCTV subsystem,radar subsystem,AIS subsystem,RFID subsystem and laser Scanning subsystem.Its information transmission layer is composed of existing Yangtze shipping information network and the public communication network,and its information processing layer is made up of traffic flow database,electronic waterway map and information processing system.Key technologies of AIS subsystem,RFID subsystem and laser Scanning subsystem are analyzed,and prospects of the future research are brought forward.
