基于场景交互理论的智能道路清扫车安全设计研究

Safety Design of Intelligent Road Sweeper Based on Scene Interaction Theory

目的通过“场景交互理论”分析智能道路清扫车作业安全问题,以进行科学、合理的作业安全警示方式创新设计。方法基于场景交互理论内涵,将城市智能清扫语境下的交互场景细分为内部智能场景和外部现实场景;依据现实场景中道路使用者与智能道路清扫车交互关系的特殊性,构建以作业安全设计为目标的场景交互五要素,对主流作业安全警示方式进行分析得出创新方向;基于投影技术进行作业安全警示方式的框架构建和模块的结构设计,完成了作业安全警示图案的尺寸设计、位置设计及图案内容设计的方法构建。结果利用Lumion对设计方案进行了3D模拟,验证了其合理性。结论基于场景交互五要素设计的投影作业安全警示图案可为道路使用者营造更为安全的道路交通环境。

The work aims to analyze the operation safety of intelligent road sweepers through the"scene interaction theory"to carry out scientific and reasonable innovative design on operation safety warning methods.Based on the con-notation of scene interaction theory,the interaction scene in the context of urban intelligent cleaning was subdivided into internal intelligent scene and external realistic scene.According to the particularity of the interactive relationship between road users and intelligent road sweepers in real scenes,five elements of scene interaction aiming at operation safety de-sign were constructed,and the innovation direction was obtained by analyzing the mainstream operation safety warning methods.Based on the projection technology,the framework construction and module structure design of the operation safety warning mode were carried out,and the size design,location design and pattern content design methods of the op-eration safety warning pattern were completed.The design scheme was simulated by Lumion in 3D and its rationality was verified.The projection operation safety warning pattern designed based on the five elements of scene interaction can create a safer road traffic environment for road users.
