基于4G的自动化施肥控制系统设计

Design of Automatic Fertilization Control System Based on 4G

为推动施肥机的智能化、多元化发展,以STM32单片机为中心设计了一款智能施肥控制系统。系统采用C语言设计,结合4G网络通信,实现了设备的远程控制、远程充值、运行状态实时监测。在实验室和试验田中进行验证,试验结果表明该系统能根据行驶速度并利用比例-积分-微分(Proportional Integral Differential,PID)算法实时调整施肥电机的转速,从而达到精准施肥的要求,施肥误差平均值为3.02%。

To promote the intelligent and diversified development of fertilizer spreaders.An intelligent control system for fertilizing machine is designed with STM32 microcontroller as the center.The system uses C language design,combined with 4G network communication,to achieve remote control of equipment,remote recharge,real-time monitoring of equipment operating status.It is verified by the laboratory and the test field.The test results show that the system can adjust the rotation speed of the fertilization motor in real time according to the speed of the driving speed and use the proportional integral differential(PID)algorithm to achieve precise fertilization requirements.The average fertilization error of the fertilizer is 3.02%.
