集装箱式植物工厂系统优化设计与集成验证

Optimal Design and Integration Verification of a Containerized Plant Factory System

摘要: 集装箱式植物工厂作为模块化、可移动的智慧农业设施，在解决特殊环境下的蔬菜供应问题方面具有重要应用价值，但现有方案存在空间利用率低、能耗高、环境控制精度不足等问题。本文以40英尺标准集装箱为载体，针对上述问题，对保温结构、循环风道系统、立体种植架及综合控制系统进行了系统优化设计。通过CFD风道模拟、有限元结构分析及实验验证，结果表明：优化后的系统温度控制精度达±1℃，湿度控制精度达±10% RH，CO₂浓度控制精度达±100 ppm。以金线莲‘红霞’为栽培对象的实验证实了系统的综合性能。本研究为移动式植物工厂的工程化应用提供了一套完整的优化集成方案。

Abstract: As a modular and mobile smart agricultural facility, the containerized plant factory has important application value in solving vegetable supply problems in special environments. However, existing solutions suffer from low space utilization, high energy consumption, and insufficient environmental control accuracy. In this study, a 40-ft standard container was used as the carrier, and systematic optimization was conducted on the insulation structure, circulating air duct system, three-dimensional planting rack, and integrated control system to address the above issues. Through CFD air duct simulation, finite element structural analysis, and experimental verification, the results showed that the optimized system achieved a temperature control accuracy of ±1˚C, a humidity control accuracy of ±10% RH, and a CO₂ concentration control accuracy of ±100 ppm. An experiment using Anoectochilus roxburghii ‘Hongxia’ as the test plant confirmed the overall performance of the system. This study provides a complete optimized integration solution for the engineering application of mobile plant factories.
