摘　　要：针对目前高空作业人员初期训练手段较少、安全性不高等问题,研制一套虚实融合的高空应激诱发系统,系统由物理反馈、高空虚拟场景和多维数据传输等模块组成。对木板进行倾斜角度设计和静应力载荷仿真,在保障系统安全的前提下提升高空应激强度;构建迷雾粒子特效,消除高空虚拟场景边界线暴露问题,同时减少渲染内容以提高帧率;组织志愿者身穿智能衣采集生理数据,验证系统效果。结果表明,与其他高空应激范式相比,系统心理应激诱发程度较高,可用于高空应激测试训练与儿童防坠楼教育。In order to address the current scarcity of initial training methods for high-altitude workers and concerns about safety,a virtuality-reality combination-based high-altitude stress induction system was developed.The system comprises modules of physical feedback,high-altitude virtual scenarios,and multi-dimensional data transmission.The plank module is designed with an inclination angle and subjected to static stress load simulations,ensuring system safety while enhancing the intensity of high-altitude stress.Fog particle effects are constructed to eliminate the exposure of boundary lines in high-altitude virtual scenes.Additionally,we reduced rendering content to improve frame rates.The system’s efficacy was validated through an experiment involving five volunteers wearing smart clothing to collect physiological data.The results indicate that,compared to other high-altitude stress paradigms,this system elicits a higher degree of psychological stress,making it suitable for high-altitude stress training and child fall prevention education.
