【摘要】：随着变电站综合大检修和状态检修的不断深入,变电站临停临检所做的班前会已经满足不了多班组、多专业协同工作的要求。本文研究将三维建模技术、虚拟现实技术、远程视频采集技术、UWB无限脉冲定位技术相结合,研发基于虚拟现实的变电检修综合布控系统。本系统实现了变电检修前的布控模拟功能,方便检修人员在虚拟变电站中进行多专业、多班组的协同桌面推演;同时与具有网络功能的变电检修智能单兵作业装置集成,并以该装置为现场信息采集手段,实现检修过程的远程管控,包括远程安全监督和远程技术支援;检修完成后,管理人员可以借助本系统回放检修过程,对检修过程进行研讨和分析,优化提升检修方案,为下次检修提供经验;此外,本系统还专门为初级员工提供专业的变电检修培训功能,让员工快速掌握变电检修布控技能。技术实现上本系统按照1:1比例建立高仿真变电检修场景,通过基于多人协同的分布式虚拟现实布控在三维场景中标注工作区域及危险点,实现检修前的三维布控模拟;通过坐标匹配与TDOA相结合的测量技术将三维场景与现实人员定位相结合,实现现场人员位置预警;同时通过视频采集安全帽收集现场音视频信息,与指挥中心进行视频语音交流,实现变电检修现场的突发情况的远程问诊。本系统通过三维仿真平台进行展示,采用离线语音合成,将危险信息通过语音的形式进行现场预警,达到定位精确、控制方便、展示生动、预警提示全面的目的。本系统的应用能够提高布控效率,降低检修现场事故发生率,大幅度提高检修工作效率。
[Abstract]:With the deepening of substation comprehensive overhaul and condition maintenance, the pre-shift meeting of substation temporary inspection can not meet the requirements of multi-team and multi-professional cooperative work. In this paper, 3D modeling technology, virtual reality technology, remote video capture technology and UWB infinite pulse positioning technology are combined to develop a comprehensive distribution and control system of substation maintenance based on virtual reality. The system realizes the simulation function of distribution and control before substation maintenance, which facilitates the maintenance personnel to carry on the cooperative desktop deduction of multi-specialty and multi-team in virtual substation, and integrates with the intelligent single military operation device of substation maintenance with network function, and takes this device as the field information collection means to realize the remote control of maintenance process, including remote security supervision and remote technical support. After the maintenance is completed, the management can use the system to play back the maintenance process, discuss and analyze the maintenance process, optimize the maintenance scheme, and provide experience for the next maintenance. In addition, the system also provides the junior staff with the professional substation maintenance training function, so that the staff can quickly master the substation maintenance layout and control skills. The technical realization of the system is to establish a high simulation substation maintenance scene according to the 1:1 ratio, and to realize the 3D distribution and control simulation before maintenance by marking the working area and dangerous points in the 3D scene by distributed virtual reality distribution and control based on multi-person coordination, and to realize the field personnel position early warning by combining the 3D scene with the realistic personnel positioning through the measurement technology of coordinate matching and TDOA. At the same time, the audio and video information is collected through the video capture helmet, and the video voice communication is carried out with the command center to realize the remote consultation of the emergency situation on the spot of substation maintenance. The system is displayed through three-dimensional simulation platform, adopts off-line speech synthesis, and carries on the field early warning of dangerous information in the form of voice, so as to achieve the purpose of accurate positioning, convenient control, vivid display and comprehensive early warning prompt. The application of this system can improve the efficiency of distribution and control, reduce the incidence of on-site accidents, and greatly improve the efficiency of maintenance.
