摘  要:
针对我国精准农业中变量喷雾技术的发展需求现状,对精准变量喷雾控制系统进行了研究。根据农作物喷雾系统的工作原理(即保证农田单位面积喷雾量恒定的喷雾作业),对喷雾作业中的数据进行实时检测,为设计的核心内容。对农作物喷雾系统的动态响应进行试验分析,结果表明:农作物喷雾系统在工作状态下,系统的动态性能良好;根据模拟车速的变化,实时记录控制器流量、实际流量与理论设定喷雾量并进行分析,结果表明:农作物喷雾系统控制喷雾量满足了设定要求。

摘  要:
For the current development needs of Precision Agriculture Variable spray technology,the paper precision variable spray control system research. Based on technical requirements,by means of analysis of closed-loop control principles and crop sprayer controller works through modular design method,we developed a microcontroller to control the core,control valve actuators for the controller design,depth of research programs around. Dynamic response to crop spray controller test analysis,test results showed that crop sprayer in working condition,good dynamic performance of the controller; Finally,according to changes in simulation speed,real-time recording control flow rate,the actual flow rate and spray amount set theory to analyze test results show that crop sprayer spray volume controller to meet the set requirements.
