摘要: 为保证大田有机肥撒施量精确可控,符合大田作物生长需求,设计一个基于BP神经网络算法的固体有机肥撒施装置控制系统。该系统配套设备采用链板及挡肥板配合控制撒肥量的固体有机肥撒施机,控制系统以数据采集与监视控制系统(SCADA)为核心,人机交互由触摸屏实现。通过输入大田基础肥料需求量为控制算法提供基础数据,结合车辆行进速度,采用动量BP神经网络算法先行对挡肥板开度进行控制并为输肥链板转速控制提供输入值,再利用弹性BP神经网络算法对及链板转速进行控制。实验结果表明,控制系统能够根据设定的基础肥料需求量及车辆行进速度,实时改变挡肥板开度及撒肥机链板转速,撒肥量控制偏差小于9%。

Abstract: In order to ensure that the amount of organic fertilizer applied in the field is accurately controllable and meets the needs of field crop growth, a solid organic fertilizer application control system based on BP neural network algorithm is designed. The supporting equipment of the system adopts a solid organic fertilizer spreader with chain plate and fertilizer baffle to control the amount of fertilizer. The control system is developed based on supervisory control and data acquisition (SCADA), and the human-computer interaction is realized by the touch screen. The basic data of the control system is provided by the actual demand for basic fertilizer in farmland and input into the system through the input box. According to the speed of the vehicle, the momentum BP neural network algorithm is used to first control the opening size of the fertilizer blocking device and provide an input value for the rotating speed control of the fertilizer chain plates. Finally, the elastic BP neural network algorithm is used to control the rotating speed of the fertilizer chain plates. The experimental results show that the control system can change the opening size of the fertilizer blocking device and the speed of the chain plate of the fertilizer spreader in real time according to the set basic fertilizer demand and the traveling speed of the vehicle, and the control deviation of the fertilizer amount is less than 9%.
