The invention discloses a PID control plant protection unmanned aerial vehicle spraying system and method, and the system comprises a sensor module, a flight controller module, a central processor module, a PID controller module, and a spraying module. The sensor module is used for detecting the real-time flight speed of the plant protection unmanned aerial vehicle and the height away from crops,converting the collected sensor data through an A/D converter and then transmitting the data to a flight controller; the flight controller packages and transmits speed information and radar height information to a PID controller module, and the PID controller calculates the speed information, the height information and flow information transmits the speed information, the height information and the flow information to a central processor module, and outputs new flight data and flow spraying data after operation, and the spraying system performs spraying. By means of the mode, the problem thatorganization flow spraying is difficult to control can be effectively solved, and spraying operation can be carried out more finely.

    本发明公开了一种PID控制植保无人机喷洒系统和方法,包括传感器模块、飞行控制器模块、中央处理器模块、PID控制器模块和喷洒模块,传感器模块用于检测植保无人机实时的飞行速度和距离作物的高度,把采集到的传感器数据经过A/D转换器转换后传输给飞行控制器,飞行控制器把速度信息和雷达高度信息打包传输给PID控制器模块,PID控制器把速度信息、高度信息和流量信息进行计算后传输给中央处理器模块,运算和后输出新的飞行数据和流量喷洒数据并由喷洒系统进行喷洒。通过上述方式,本发明能够有效解决组织流量喷洒难以控制的问题,可以更加精细的实施喷洒作业。
