摘要
本研究设计了集成式智能灌溉阀门远程控制系统。该系统以STM32L151C8T6为主控硬件,以2W-025-08型电磁阀为核心,结合远距离无线电(Long Range Radio,LoRa)、4G双模通信实现低功耗远程控制,采用模糊控制模型为控制策略,运用遗传算法优化控制策略。仿真实验表明,与传统阈值法相比,优化后的控制算法策略使智能阀门超调量降至3.1%,调节时间缩短至18 min。稳态误差收窄为±1.8%。在山东寿光的番茄温室中实地部署后,单位平均用水量能够减少19.52%,表明该系统能够缩短温室大棚的灌溉时长,提升灌溉精度,减少灌溉用水量,从而为智慧农业发展提供可靠的技术支撑。
This study designed an integrated intelligent irrigation valve remote control system.The system is mainly controlled by STM32L151C8T6,with 2W-025-08 solenoid valve as the core,combined with Long Range Radio(LoRa)and 4G dual-mode communication to achieve low-power remote control.Fuzzy control model is adopted as the control strategy,and genetic algorithm is used to optimize the control strategy.Simulation experiments show that compared with the traditional threshold method,the optimized control algorithm strategy reduces the overshoot of the intelligent valve to 3.1%and shortens the adjustment time to 18 minutes.The steady-state error narrowed to±1.8%.After on-site deployment in the tomato greenhouse in Shouguang,Shandong,the average water consumption per unit can be reduced by 19.52%,indicating that the system can shorten the irrigation time of the greenhouse,improve irrigation accuracy,reduce irrigation water consumption,and provide reliable technical support for the development of smart agriculture.
