基于EVC的嵌入式导航电子地图设计

Design of embedded navigation digital map based on EVC

针对嵌入式系统的特点,设计并开发了一种基于Windows CE操作系统平台的嵌入式电子地图系统。利用Visual C++6.0实现地图数据的解析与转换;设计了一种适合于嵌入式设备运行的地图数据结构;以EVC 4.0为平台,采用双缓冲技术实现电子地图的绘制。实验结果表明该电子地图系统简单易行,所占资源小,运行良好,可用在移动设备、导航等领域,具有较好的实用价值。

Considering the feature of the embedded system, an embedded digital map system based on Windows CE operating system was designed and developed. The resolution and conversion of the map data were realized using the Visual C ＋＋ 6.0; a map data structure for embedded devices was designed; the drawing of the digital map was realized through double buffering technique based on EVC 4.0. The experiments indicate the simple and feasible digital map system takes fewer resources and runs good, which can be used in mobile devices, navigation, etc., with good practical value.
