中文摘要：针对传统海水稻育秧方式中存在的土地利用效率低和人力财力资源浪费的问题。设计开发了一个以三菱PLC为核心,配合堆垛架、步进电机、电机驱动器、距离监测器、旋转增量解码器、光敏电阻、环境传感器、A/D采集模块、LED灯片矩阵、喷灌一体化装置等器件为一体的密集型海水稻大棚育秧种植系统。在该系统中,PLC通过A/D采集模块接收来自距离传感器的信号,并转换成脉冲信号输出给电机驱动器来驱动步进电机的转动,同时旋转增量解码器将接收步进电机的旋转量信号并转换成脉冲信号反馈给PLC从而达到闭环控制的效果,使定位更加精确。系统照明辅助装置以及智能培育装置中,分别采用光敏电阻和环境传感器为信号接收源并通过A/D采集模块将信号输入PLC中,然后通过PLC来控制LED灯片矩阵以及喷灌一体化装置。通过仿真、试验和分析计算,验证了设计方案的可行性,该系统大幅提高空间利用率,减少了资源的浪费,有效提高了秧苗的质量。

外文摘要：In response to the issues of low land utilization efficiency and waste of human and financial resources in traditional sea rice seedling cultivation methods,a compact sea rice seedling cultivation system for greenhouse cultivation is designed and developed.The system centers on the Mitsubishi PLC and integrates components such as stacking racks,stepper motors,motor drivers,distance monitors,rotary incremental encoders,light-dependent resistors,environmental sensors,A/D acquisition modules,LED matrix light panels,and integrated irrigation and spraying devices.In the system,the PLC receives signals from the distance sensors through the A/D acquisition module,converts them into pulse signals,and outputs them to the motor driver to drive the rotation of the stepper motor.Meanwhile,the rotary incremental encoder receives the rotation signal from the stepper motor,converts it into a pulse signal,and feeds it back to the PLC to achieve closed-loop control,thereby achieving more precise positioning.In the system′s lighting assistance devices and intelligent cultivation devices,light-dependent resistors and environmental sensors are used as signal receivers,respectively.Both of them input signals into the PLC through the A/D acquisition module,and the PLC controls the LED matrix light panels and the integrated irrigation and spraying devices accordingly.Through simulation,experimentation,and analytical calculations,the feasibility of the design is verified.This system significantly improves space utilization,reduces resource waste,and effectively improves the quality of seedlings.
