摘要
针对土地面积的精准测量的需求,研制了一种基于GPS卫星定位的面积测量装置。该装置由数据处理模块、GPS北斗模块、电源模块、人机交互模块等组成;软件基于μC/OS-Ⅱ,将系统划分为主控任务、定位数据接收、面积计算、界面显示等4个任务。该仪器能够利用所接收的定位信息计算土地面积并在液晶屏上显示。
The portable agricultural area measuring device based on GPS satellite positioning is designed for the demand for accurate measurement of land area. The mode is composed of data processing module,GPS Beidou module,power module and Human-computer interaction module. Based on the software of μC/OS-Ⅱ system is divided into 4 tasks:the main control task:positioning data receiving task,area calculation task,interface display task. Using the received location information to calculate the land area and display on the LCD screen.
