摘要
电气、用火不慎引燃可燃物是我国建筑施工现场火灾频繁发生的主要原因,通过智能提示保持使用中的火源设备和大体积可燃物之间的安全距离可预防火灾发生,自动判定它们之间是否突破安全距离成为亟待解决的关键问题。基于国内外现有的研究成果和最新研究进展,提出了RFID移动目标定位与虚拟现实场景实现碰撞检测相结合的方案。基于RFID技术的目标定位算法实时感知移动火源设备位置并更新虚拟场景中模型的坐标,三维模型的碰撞检测确保火源设备移动使用时一旦与可燃物突破安全距离,立即产生警报信息发送到现场硬件模块提醒相关人员做好防护措施。
： Combustibles ignited by careless use of fire and electric fire are the main cause of frequent fire in the construction site. Keeping a safe distance between portable fire equipments and bulky combustible by smart tips can prevent fires. Determining the safe distance between them automatically is a key issue to be resolved. Based on the latest scientific achievements and development at home and abroad, a scheme combining the RFID target location and collision detection in virtual reality scene is proposed. With the help of RFID, real-time location of mobile fire equipment can be obtained and update the model coordinates in the virtual scene. By collision detection of these 3D models, it is ensured that once safety distance between mobile fire equipments and combustible is breakthrough alarm information will immediately be sent to the scene hardware modules and alert relevant people to take precautions against fire.
