摘　　要：针对农机精准作业规模化管理与农机作业服务计费需要准确的农机作业面积,设计北斗导航农机作业面积管理系统,其中包括北斗导航农机作业面积管理终端和北斗导航农机作业面积管理平台,实现农机作业面积测量与管理。基于北斗卫星导航定位系统、北斗地基增强系统及ARM32位Cortex-M3处理器设计并开发管理终端,采集农机作业位置信息;同时采用C#、JAVA语言及SQL Server 2008数据库设计并开发前后端分离结构的管理平台,实现农机作业监控、面积测量、数据统计等功能。通过田间试验,检验管理终端定位误差和管理平台面积测量精度。试验结果表明,该系统能够实现农机工作时间、工作地点、作业面积、作业轨迹等信息实时记录和回放。北斗导航农机作业面积管理终端水平定位误差仅为2.7 cm,作业面积平均测量误差为1.818%。该系统能够精准测量农机作业面积。Aiming at the accurate agricultural machinery operation area required by agricultural machinery precision operation scale management and agricultural machinery service charge,Beidou Navigation agricultural machinery operation area management system was designed.It was capable of measuring and managing operation area precisely with the combination of Beidou Navigation agricultural machinery operation area management terminal and Beidou navigation agricultural machinery working area management platform.To monitor operating location information,the management terminal was designed and developed with support from Beidou satellite navigation and positioning system,Beidou ground-based enhancement system and ARM32-bit Cortex-M3 processor.To implement funtions include operation monitoring,area measurement,data statistics and so on,C#、JAVA and SQL Server 2008 database were used for the design and development of front-end separation architecture management platform.The management terminal positioning error and the measuring accuracy of the management platform area were tested by field experiment.The result showed that the system could realize the real-time recording and playback of the agricultural machinery working time,working place,working area and working track.The horizontal positioning error of agricultural machinery operation area management terminal was only 2.7 cm,the average measurement error of the operating area was 1.818%.The system can accurately measure the agricultural machinery operations area.
