中文摘要：

针对港口现场物流过程,港机健康状态等监测问题,提出一种分布式港口监测系统,并着重研究其监测终端子系统中的虚拟港口可视化建模.该虚拟港口将全球定位（GPS）技术、地理信息系统（GIS）技术与虚拟现实（VR）技术相结合,基于分布式港口监测系统实现对港口的虚拟可视化监测.通过构造港机零部件标准3D模型库,实现对虚拟港机面向对象的层级模块化几何建模和GPS数据驱动的运动建模.在构建的分布式港口监测系统网络原型上的测试实验表明,此建模方法能够满足监测可视化要求.

英文摘要：

This paper presented a distributed monitoring system for a container terminal with regard to monitoring container terminal logistics procedures and machine health states. Furthermore, the visual modeling of virtual container terminal （VCT） in a monitoring client was discussed. The VCT that is an integration of global position system （GPS）, geography information systems （GIS） and virtual reality （VR） technologies, can achieve virtually visual monitoring for container terminals under the support of the distribu- ted monitoring system. With a pre-built 3D model library of port machinery parts, an object-oriented modulized hierarchical geometry modeling and a GPS data driven movement modeling make virtually monitoring the working procedures of machines possible. The test on a network prototype of the distributed monitoring system demonstrates that this modeling method can satisfy the monitoring requirements.
