Virtual Simulation for Training of Oil-field Safety Task Operation

利用虚拟现实技术构建油田安全作业虚拟仿真训练系统,提供交互式训练功能。提出了封闭式演示、指南式向导操作和开放式自由操作三种培训模式,给出了油田安全作业虚拟仿真训练系统的开发框架,定义了虚拟人基本动作及其参数化表示,解决了行为定义以及可重用性问题,并对虚拟人的操作手形进行了分类。最后从感知环境、行为控制、运动控制和碰撞检测四个方面分析了场景驱动执行引擎的功能,协调虚拟人和操作物体的交互活动,控制虚拟场景的变化。本系统的应用有效地解决了油田安全作业培训的成本、安全和效果问题。

Virtual simulation for the training system of oil-field safety task operation was created based on virtual reality technology. This system has the function of interactive training. Close demostration, guided operation and open operation training mode were proposed. The development framework of 3D interactive virtual simulation was given and the developed process and technologies of four stages for the framework are discussed in detail The virtual human elementary actions which used to represent the simulation were abstracted to resolve behavior defining and re-availability. Hand shapes of virtual human appeared in virtual simulation were also classified and described. Finally, the functions of scene driving engine were introduced by descriptions of perception environment, behavior controlling, motion controlling and collision detecting, which coordinated the interactive action between virtual human and operated objects and controlled the changes of virtual scene. The cost, safety and effect for the training of oil-field task operation can be effectively improved by application of our system.
