便携式GPS轨迹记录仪方案的设计

摘要

The applications of global positioning system(GPS)are more and more widely used in people’s life. With a high precision, long standby time, global coverage, convenience, flexibility and high quality but low price, the GPS plays an essential role to people around the world. At present, GPS positioning and navigation technologies are not only used in geodesy, vehicle location and other professional fields, but also in the individual applications. According to the individual applications, the portable GPS track logger scheme has been designed and developed, basing on the STR711FR2 micro control unit(MCU)of STMicroelectronics and the GPS receiving module of MStar. The paper emphasizes on the parts of software which is based onμC/OS-II embedded operation system. The subject designs a software system that can meet the requirement on portable GPS track logger and realize four founctions which include communication function, connecting function, storage function and human-computer interaction function.%　　全球定位系统（GPS）在生产生活中的应用越来越广泛，全世界需要导航、定位的用户中绝大多数都被GPS的高精度、全天候、全球覆盖、方便灵活和质优价廉的特点所吸引。目前，GPS定位导航技术不仅应用于大地测量与车辆定位等专业领域，在个人应用方面也相当广泛。为此，文章主要针对个人应用方面，设计开发出了基于意法半导体公司STR711FR2微控制器（MCU）和MStar公司的GPS接收模块的便携式GPS轨迹记录仪的方案。文章主要侧重软件部分，其中软件系统基于μC/OS-II嵌入式操作系统。文章完成了四个功能的实现，包括通信功能、连接功能、存储功能、人机交互功能。
