[Objectives] In response to the practical challenges encountered in the hilly agricultural equipment training within agricultural higher vocational colleges, specifically, “the inability to access real scenarios, afford actual equipment, and fully practice real processes”, a virtual-real fusion training system has been developed, and the effectiveness of this system is demonstrated through its application to mountain drip irrigation technology. [Methods] Utilizing the actual technology project titled “Research and Promotion of Integrated Application of Internet of Things Drip Irrigation Technology in Mountain Planting” as a technical blueprint, a three-tiered progressive training model comprising “virtual simulation, semi-physical joint debugging, and real scene verification” has been developed. It includes four core skill modules: terrain mapping and pipeline network design, LoRa wireless networking, fuzzy PID water and fertilizer decision-making, and cloud-edge collaborative platform operation and maintenance. The framework is also supported by a practical training management platform alongside an assessment and evaluation system. [Results] In the pilot implementation of the system at Huizhou Engineering Vocational College, the per-student training cost has been reduced by approximately 70% compared to the traditional “whole-orchard field attachment” model. Students are able to complete typical training scenarios, such as 30°slope irrigation uniformity control and 1500-m LoRa communication range, without leaving the campus. Furthermore, their capabilities in managing the entire closed-loop process have been significantly improved. [Conclusions] This system has implemented a practical training teaching reform characterized by “real project-driven, real data training, and real scene transfer”, thereby offering a replicable practical pathway for agricultural higher vocational colleges situated in hilly agricultural regions. |
