| 摘 要： | 综合应用Ext JS、AJAX、MySQL等技术设计并实现了一个基于GPS/GPRS/Web的位置服务系统。它主要有移动终端、互联网络、数据网关、位置服务网站和电子地图等几部分组成。在系统实现过程中,为避免对特定终端的依赖,采用数据网关兼容多款终端方式接入系统;为减少电子地图对系统的侵入性,采用适配器模式调用电子地图。为解决B/S架构中实时性较差的问题,采用推送技术,将终端的位置信息推送到客户端浏览器。实践表明:它是一个能够兼容多款终端、为用户提供终端监控和导航服务的位置服务系统。

| Abstract: | This paper design and implement a location service system based on GPS/GPRS/Web. It includes terminal, mobile Internet, general gateway, LBS website and electronic map. In the process of implementing, it adopt general gateway compatible with various terminals to reduce the dependence of specific terminal; use electronic map adaptor to reduce the incursion of electronic map; adopt the push technology to deliver terminal location information to the client browser, and so as to solve the poor instantaneity existing in B/S structure. As Experience proves, it has the compatibility to a lot of (mobile) terminal, and can provide (mobile) terminal supervisory and navigation service. |
