摘要
本课题旨在设计一套基于PLC的家用水培蔬菜控制系统，以契合现代家庭智能化种植的要求。此系统具备自动监测环境参数、智能调控、以及远程监控等多项功能。
设计伊始，充分考量水培蔬菜的生长所需，遵循模块化理念开展硬件与软件设计工作。硬件设计重点涵盖核心控制器的挑选以及各功能模块的构建，具体有PLC控制模块、集温湿度/光照/CO?于一体的四合一环境传感器、PH值检测、液位传感器、执行机构驱动模块以及无线通信模块等部分。软件设计依托STEP7-Micro/WIN开发环境，运用梯形图编程语言达成数据采集、自动控制、报警管理以及通信协议等关键程序的设计。经系统联调对控制参数加以优化，成功处理了传感器干扰、执行机构响应滞后等难题，达成水培蔬菜生长环境的精确控制与智能化管理。该系统借助规范的电气接线与通信协议，让各模块协同运作，为家庭用户打造出一套稳定可靠、操作便捷的智能种植系统。
