摘　　要：针对目前农机作业中信息发布滞后、农机资源调度不合理、效率低下等问题,提出一种基于地理信息系统(GIS)、通用分组无线业务(GPRS)及全球定位系统(GPS)技术的农机监控调度系统,运用GPRS数据传输技术和GIS组件MapObjects,实现农机作业信息的即时采集与监控调度。为满足实时计算的需要,采用A-Star寻路算法规划农机的调度路径。应用结果表明,该系统能有效管理和调度农机,提高作业效率。To solve the problems in agricultural machinery working field, such as information lag, lack of effective means of scheduling agricultural machinery, and low efficiency, an agricultural machinery monitoring and scheduling system integrated with Geographic Information System（GIS）, General Packet Radio Service（GPRS） and Global Positioning System（GPS） technologies is presented. To realize data collection immediately and real-time monitoring and scheduling agricultural machinery remotely, GPRS data transmission technology and MapObjects are adopted in the system. To overcome traditional pathfinding algorithm＇s shortcomings in real-time computation, A-Star algorithm is applied to plan the route of agricultural machinery. Application results show this system can schedule agricultural machinery effectively and improve the efficiency.
