园艺设施建造与系统安装虚拟仿真课程构建初探

A Preliminary Study on the Construction of a Virtual Simulation Course for Horticultural Facility Construction and System Installation Guided

园艺设施建造与系统安装是设施农业科学与工程专业课程《温室建筑与结构设计》的拓展版块,课程在温室设计的基础上重点介绍常见温室类型(拱棚、日光温室、圆拱型连栋温室、锯齿型连栋温室、文洛型连栋温室等)的建造与安装,以功能及构造划分,包括温室的基础建造、温室主体钢骨架建造、加温与通风系统安装、开窗拉幕系统安装、温室覆盖系统安装、温室控制系统安装等。传统的温室建造与系统安装实验教学受场地和实验周期的限制,只能采用分散教学的形式进行,由于时间限制,学生只能接触和了解到其中某一环节,实验开展效果不佳,难以达到提升温室建造职业技能的效果。以工程建模和虚拟仿真为技术手段,通过三维图形的直观认识及动画施工模拟,激发学生的学习兴趣,培养学生读图、识图能力,加深其对温室建造和安装技术的理解运用能力,促进职业技能的提升。

The construction and installation of horticultural facilities is the core content of the Greenhouse Design course in the field of facility agriculture science and engineering.The course introduces the design and construction of various common types of greenhouses(arch greenhouse,solar greenhouse,circular arch multi-span greenhouse,serrated multi-span greenhouse,Venlo multi-span greenhouse,etc.)systematically,including the structural design of greenhouse buildings,main steel frame assembly,heating and ventilation design of greenhouses,the principle and design of greenhouse window opening and curtain pulling systems,the design and installation of greenhouse coverage systems,and the design of greenhouse control systems.The traditional experimental teaching of greenhouse construction and installation can generally only be conducted in a decentralized manner due to the limitations of the site and experimental period.The students can only access and understand one of the links,and the effectiveness of the experiment is not satisfactory,making it difficult to achieve the effect of improving vocational skills in greenhouse construction.This article uses engineering modeling and virtual simulation as technical means.Through the intuitive understanding of three-dimensional graphics and a systematic evaluation system,it improves students'understanding of drawings and stimulates their interest in learning.This not only improves their understanding and application of construction and installation technology,but also deepens their understanding of drawings and enhances their professional skills in horticultural facility design.
