摘要
在道路巡检过程中,需要通过GPS导航仪实时掌握巡检车辆的动态信息,因此,导航功能的设计是巡检系统实时性和准确性的基本条件。文中以MapX组件为平台,采用Visual C++开发工具,针对道路巡检的特殊环境要求,详细地探讨了GPS导航软件功能的实现。在传统GPS导航功能的基础上,如地图控制、路径规划,结合数据库系统,实现了导航仪的历史轨迹回放和实时绘制轨迹,通过GPRS无线网络能够准确地反馈道路信息给计算机终端。
In the process of road patrol,it is important to know the vehicle＇s dynamic information of whole system by GPS navigation.The realization of navigation is the basis of veracity.By the use of Visual C＋＋ and MapX component,aims at design the function of GPS navigation under the special environment of road patrol system.On the basis of tranditional GPS navigation,such as map control,path planning,the system realizes the function of trace replay and plotting real-time track curves which can feedback the road informations to the computer correctly and timely by the GPRS wireless network.
