摘　　要：利用三维激光扫描技术对变电站进行精确三维实景重构,并在虚拟仿真层面上,在三维场景平台中对变电站设备进行正常巡视和故障检修的推演仿真,形成现场作业的辅助指导方案.然后,结合惯性导航与实时视觉定位技术,获得实际工作人员、工程车辆等在变电站中的位置,分析得到实际工作人员与车辆的运动趋势,并与变电站三维实景模型中建立的高压带电危险区域进行软碰撞检测,从而实现现场作业与巡检的风险管控,及时制止作业过程中误入带电危险区域的操作.This paper uses the 3Dlaser scanning technology to reconstruct the substation in accurate 3Drealism.At the virtual simulation level,the derivation and simulation of the normal inspection and troubleshooting of the substation equipment are carried out in the 3Dscene platform,and the auxiliary guidance program of the field operation is formed.Then,combined with inertial navigation and real-time visual positioning technology,the location of actual workers and engineering vehicles is obtained to analyze their movement trends,which can be used to make soft collision detection with the high-voltage live dangerous areas of substation in 3Dreal model.The soft collision detection can achieve on-site operation and inspection of the risk control,and therefor,which can timely stop entering dangerous areas during the operation process.
