摘要
针对目前交通行业GPS应用系统普遍缺乏统一规范,数据和功能难以交换共享,存在"应用孤岛"和"资源孤岛"问题,从整合现有资源和未来资源为出发点,设计GPS综合服务平台和GPS资源中心相分离的GPS信息资源整合方案,研究了数据格式转换、中间件技术、信息传输方式、应用接口连接等关键技术,最后分析了整合系统的运营模式和价值链。
It is difficult to share the functionality and data in present GPS application systems because of the lack of uniform standard.Therefore,the ＂application island＂ and ＂resource island＂ have appeared.In order to resolve this problem,the integration scheme of GPS information resources is proposed,while both the present resources and the future ones are taken into account.The comprehensive GPS service platform and the GPS resources center are separated in this scheme.Then,such key technologies as data format conversion,middleware,transmission mode,interface of application are studied in this paper.In addition,the operation mode and value chain are analyzed.
