基于Web Service的车辆导航系统管理机制研究

通过分析现有车载导航系统存在的主要问题,提出了基于Web Service的中心服务式车辆导航服务系统的整体架构;在此基础上,讨论了服务器端数据和服务管理机制等车辆网络导航系统的关键问题的实现机制;该架构立足于适应导航数据大容量、多源化、现势性的趋势和解决导航终端计算能力不足的问题,同时也考虑传输性能和负载均衡等问题;最后,通过建立试验系统,对基于Web Service的车辆网络导航系统可行性进行了分析。

Technology of Web Service based Vehicle Navigation System

This paper discusses the disadvantage of current vehicle navigation system,and proposes the structure of a Web Service based Network Navigation System.Then,the key technologies of this structure,which include data organization and navigation service management on server,are discussed.This structure adapts to the navigation data with high-capacity,multi-source and real-time trends,and can also solute the low processing capacity on navigation terminal.An experimental prototype system has been developed to tes...
