Abstract: The training of petrochemical employees uses the model of classroom and book teaching with stereotyped content and single pattern. This training form has many deficiencies，such as loss of interest and puny abilities. With the aim of resolving the problems，a new scheme based on interactive environment was proposed. The system built the enterprise three-dimensional scene model，used inverse kinematics algorithm to resolve the data glove of interaction in scene，and a three-dimensional rendering acceleration method based on the idea of graphic processing unit was introduced. The three-dimension training system was developed based on virtual reality engine. The training made use of multimedia computer system to provide cognition cultivation，used human-computer interaction to enhance operation level，and evaluated performance by assessment modules. Finally，experimental results demonstrated that the system could help users master the operation and emergency treatment much better than traditional training and was approved by the enterprise.

摘要： 石化企业员工培训主要采用课堂式和书本式教学，培训教材固定、形式单一，存在易导致员工兴趣丧失、眼高手低、实操能力弱等不足。为解决目前企业培训中存在的诸多问题，本文提出了研发一种基于交互环境的虚拟培训系统，系统通过搭建企业三维数字化场景，利用逆运动学算法实现虚拟手对设备的交互操作，结合事故模拟专业软件，利用图形处理技术实现泄漏、火灾等事故的数值模拟和三维可视化，最终利用虚拟现实引擎研发可交互的三维培训系统，通过视频、音频等多媒体形式对员工进行认知培训，利用人机交互方式使员工在三维场景中熟悉相关操作，最后通过评估模块对员工知识掌握情况进行考核。通过实例验证，利用该系统，员工所掌握的知识和效率都优于传统的培训方法，得到企业的认可。
