农用无人机进行植保喷洒作业成为智能农业机械发展的新热点,这使得测试喷洒效果优劣、测试喷洒效果影响因素等实验需求大量增加.然而目前农用农用无人机价格仍然比较昂贵,同时安全事故频发,飞行喷洒试验周期长等因素限制了植保无人机技术的开发与应用.本研究设计并开发了一套高精度、高可控性的无人机喷洒模拟平台,并进行了试验验证效果.该系统机械部分水平精度最大误差2mm,垂直精度最大误差1mm,最大承载重量50kg,控制部分,采用MFC设计上位机控制软件,与主控板STM32通过串口进行通讯,实现对水平和垂直两个方向上伺服电机的控制,同时采用CAN总线与喷洒控制器通讯和远程操控,可以实现喷洒流量控制以及旋翼风速控制.本系统可以有效降低喷洒试验载具成本,降低试验风险,对推进无人机喷洒技术开发与测试有积极意义,并且该系统可以拓展到农业植保喷洒测试领域很多地方.
