项目摘要

As to a countermeasure to improve safety of ship navigation in congested waterways, the concept of Virtual Vessel Traffic Service (V-VTS) is established and developed. V-VTS is made of a database server set up on land and individual PC installed on board. Each ship sends own ship's information such as her position and waypoints to the server. In return the server sends information of those which are nearby her. On board the ship master can recognize information of other ships just like radar, but with much more information. Besides, the server has a function of automatic navigation subsystem. If required, the server can provide suitable operational guidance to the master such as collision avoidance manoeuvre. Marine traffic simulation system was developed to confirm the effectiveness , the applicability and feasibility of the V-VTS.It is convinced that the system is quite useful, but it should be combined with precise GPS system. Furthermore, AIS (Automatic Identification System) which will be obliged to install for large ships from 2002 by IMO (International Maritime Organization) can be used for the communication tool between the server and the individual ship. Finally, if it is connected with MARTIS (Marine Traffic Information Service, normally equivalent facility with VTS), the system and VTS will be compensate each other, i.e. the system can obtain ship data only available from radar and VTS can get information available through AIS transmission. From the practical point of view, it is expected to meet with some non-technical problems such as security, but it is worthy to investigate this direction of further research. For the AIS communication, the capacity of the transmission is another factor to be checked. At this moment, it is found the present requirement meets for congested waterways, but it will be soon reach to the limit, considering further applications such as future e-shipping business and management.

针对提高拥堵航道船舶航行安全的对策，提出并发展了虚拟船舶交通服务（V-VTS）的概念。 V-VTS由设置在陆地上的数据库服务器和安装在船上的个人PC组成。每艘船都会将自己的船舶信息（例如其位置和航路点）发送到服务器。作为回报，服务器发送她附近的人的信息。在船上，船长可以像雷达一样识别其他船只的信息，但信息量要多得多。此外，服务器还具有自动导航子系统的功能。如果需要，服务器可以向主机提供适当的操作指导，例如避免碰撞动作。开发海上交通仿真系统是为了验证V-VTS的有效性、适用性和可行性，确信该系统很有用，但需要与精确的GPS系统相结合。此外，IMO（国际海事组织）自2002年起强制要求大型船舶安装AIS（自动识别系统），可用作服务器与单船之间的通信工具。最后，如果与MARTIS（海上交通信息服务，通常与VTS等效设施）连接，系统和VTS将相互补偿，即系统可以获得只能从雷达获得的船舶数据，而VTS可以通过AIS获得可用信息传播。从实践的角度来看，预计会遇到一些安全等非技术问题，但值得进一步研究这个方向。对于AIS通信，传输容量是另一个需要检查的因素。目前来看，目前的要求可以满足拥堵航道的要求，但考虑到未来的电子航运业务和管理等进一步的应用，很快就会达到极限。
