摘　　要：为了提高港口物流专业的教学和培训效率,开发了集理论教学、物流仿真和实训操作于一体的集装箱码头装卸仿真实训系统。基于三维建模技术、遮挡剔除技术以及纹理映射技术,以Unity为平台搭建了集装箱码头三维场景;以集装箱码头装卸系统的层次模型为基础,使用面向对象的Petri网建模技术构建了集装箱码头装卸仿真模型,并采用Dijkstra算法,对码头水平运输系统进行路径规划,实现了码头装卸的动态仿真;建立车辆、岸桥等运动学、动力学数学模型,实现了对集卡、岸桥和龙门吊的实训操作。系统使用虚拟现实技术搭建了港口虚拟环境,实现了集装箱码头数值仿真功能及实训功能,为后续对集装箱码头的研究提供了基础,同时为港口物流专业提供了高度结合理论和实践的教学培训平台。应用实践表明,系统真实感强,理论与实操结合度高,教学效果良好。In order to improve the teaching and training efficiency of port logistics, a container terminal training system that integrates theoretical teaching, logistics simulation and training operations has been developed. Based on 3D modeling technology, occlusion culling technology, and texture mapping technology, the container terminal 3D scene is built on Unity. The container terminal is built using the object-oriented Petri net modeling technology based on the hierarchical model of the container terminal handling system. Dijkstra algorithm is used to plan the path of the horizontal transportation system of the wharf and realize the dynamic simulation of loading and unloading of the wharf. the kinematics and dynamics mathematical models of vehicles, quay cranes, etc. are established to realize the practical operation of trucks, quay cranes and gantry cranes. The system uses virtual reality technology to build a port virtual environment, realizes container terminal numerical simulation and training functions, and provides a foundation for subsequent research on container terminals, and a highly integrated theoretical and practical teaching and training platform for port logistics majors. Application practice shows that the system has a strong sense of reality, a high degree of integration between theory and practice, and a good teaching effect.
