教育新视野

随着我国电梯产业逐渐向智能化转型，市场对电梯装调人才的需求日益增加，但电梯行业职业教育面临实训设备昂贵易损、教学内容滞后等问题。基于此，文章融合MCD 与UG NX工业软件，构建电梯教学数字孪生系统，提出数字孪生三阶教学法。在实训设备上部署传感器，采集实际环境数据，利用UGNX软件构建高精度数字模型，并基于MCD软件，实现虚实结合教学。配合四级故障诊断训练模块，设计实验组与对照组学员对比实验，结果发现，实验组学员故障排查时间缩短58.4%，首次定位准确率达82.0%，设备维护成本降低76.6%，且系统对学员的智能评分公正率达89.0%，显著提高了电梯实训教学效果。

With the gradual intelligent transformation of Chi- na's elevator industry, the market demand for elevator in- stallation and adjustment talents is increasing.However, the vocational education in the elevator industry is faced with problems such as expensive and vulnerable training equip- ment and lagging teaching content. Based on this, this paper integrates MCD and UG NX industrial software, establishes the digital twin system for elevator teaching, and puts forward three-stage digital twin teaching method. By deploy sensors on the training equipment, collecting actual environmental data, using UG NX software to build a high-precision digital model, blended virtual-physical teaching is realized based on MCD software. By using the four-level fault diagnosis train- ing module, a comparative experiment between students in experimental group and students in control group is designed,and the results show that the fault troubleshooting time of the students in the experimental group is shortened by 58.4%, the initial positioning accuracy is 82.0%, the equipment mainte- nance cost is reduced by 76.6%, and the system's intelligent scoring fairness rate for students reaches 89.0%, significantly improving the elevator training teaching effect.
