Abstract： In western colleges and universities， there are problems such as insufficient teaching resources and disconnection between teaching content and real life in the practical training of Internet of Things. The use of virtual simulation can improve the teaching effect of practical training. The experiment only focuses on the three levels （perception layer， transmission layer and application layer） of the core technology of the Internet of things. Using the "Internet of things industry training simulation" platform， the monitoring and early warning of the data in the vegetable greenhouse are realized. The host computer program is compiled to display the data， draw the curve and observe the dynamic change trend. The practical results show that through this comprehensive design case， the students' ability of analysis， design and comprehensive practice of the Internet of things system is improved， and their enthusiasm for learning is stimulated.

Key words： Internet of things; intelligent agriculture; virtual simulation; comprehensive training

物聯網作為一門新型交叉學科，涉及通信技術、傳感技術、網絡技術等，被認為是信息時代的第三次浪潮[1]。物聯網專業實踐教學體系中，綜合實訓是實現人才培養目標、提升學生綜合實踐能力的重要環節。傳統物聯網實訓環節存在一些不足，如實驗教學內容過于陳舊，與實際生活脫節;綜合性實驗較少，不能融合多學科知識;實驗內容多為驗證性實驗，學生積極性不高[2]。對于西部地區應用型本科院校來講，實驗室建設經費不足，實驗教學資源不充裕，教學效果不理想;為了能夠滿足實踐教學的需求，虛擬仿真系統逐漸成為教師關注的熱點。

因此，將虛擬仿真系統引入綜合實訓課程，不僅有效緩解實驗教學資源匱乏的問題，而且仿真系統逼真的實驗環境有效的還原真實的實驗情境，提升學生學習的積極性。……
