摘要：受到部分交通设施限载和限高的影响,货车司机需要合理的导航路径规划,该路径规划既要满足全路径交通设施限载和限高,又要实现运行的最小成本,目前缺乏高效的算法流程,因此本文对基础路网进行拓扑,提出了将道路上的货车限制信息相匹配,形成面向货车的约束路网,考虑道路约束信息对路径规划的相互关系,通过计算通行成本,标记合适道路,构建面向超载超限货车的导航系统路径规划方法。最后本文以浙江大学紫金港校区区域为例,构建了与地图相匹配的路径规划算法,展示了货车路径规划工作原理的工作逻辑。Affected by some traffic facilities with load and height restrictions, truck drivers need reasonable navigation path planning, which should satisfy the full path traffic facilities with load and height restrictions, and also realize the minimum cost of operation, so this paper topologizes the basic road network, proposes to match the truck restriction information on the road to form a truck-oriented constrained road network, and considers the interrelationship of road constraint information on path planning. By calculating the access cost and marking the suitable roads, the path planning method of the navigation system for overloaded and overloaded trucks is constructed. Finally, this paper takes the Zijingang campus area of Zhejiang University as an example, constructs the path planning algorithm matching with the map, and shows the working logic of the working principle of truck path planning.

摘要：在BIRTV2004展会上，由大洋公司和中央电视台合作建设的国家音像资料馆媒体资产管理系统项目，获得了应用大奖。此项目系统涵盖了对视／音频数据从产生、处理、存储、检索到发布的完整生命周期的管理，大洋参与了存储管理平台，编目检索系统、资料上载、下载处理系统、转码中心，视听审看系统的设计建设和软件开发。如何将相关技术和实施经验应用在城市电视台较小规模的媒资系统中，是一个富有挑战性的问题。通过苏州广播电视总台的媒资系统项目，大洋又做出了新的尝试，提供了适用的解决方案。
