摘要
我国架空输电线路覆盖范围广,地形复杂,环境恶劣。因此,电力检测已成为保证电力系统安全稳定的重要任务。近年来,无人机(UAV)在巡检中的应用,克服了人工巡检的大部分缺点,引起了广泛的关注和实施。然而,目前无人机检测的运行对操作人员的技术要求仍然很高,需要两个或两个以上的操作人员同时配合。为此,基于虚拟现实技术和人在环设计思想,提出了一种采用头部跟踪控制和第一视角技术的无人机线路检测系统。借助于该系统,操作者只需转动头部即可观察无人机的周围环境,获得具有深度信息的实时场景。通过模拟实验,该检测系统能在110 kV电压水平和距电力线1.7 m的距离下有效工作。与目前广泛使用的无人机巡检相比,该系统将把巡检作业的安全性和效率提高到一个更高的水平,实现了将操作人员由两人以上减少到一人以上的目标。
In China,Overhead Transmission Lines cover a wide range of areas,and cross complex terrain as well as harsh environment.Therefore,power inspection has become an essential task to ensure the safety and stability of the power system.In recent years,the application of UAV(Unmanned Aerial Vehicle)in the inspection,which has overcome most shortcomings of manual lines inspection,has attracted wide attention and implementation.However,the operation of UAV inspection nowadays still requires high level of techniques for the operator,and it needs two operators or above to cooperate simultaneously.For this reason,based on the Virtual Reality(VR)technology as well as the Man-In-The-Loop design concepts,a UAV lines inspection system that uses the head-to-tracking control and the technology of the first person of view(FPV)is proposed in this paper.With the help of this system,the operator can observe the ambient environment of the UAV and obtain real-time scene with depth information simply by turning his head.By carrying out simulated experimentsˋthe inspection system can work efficiently under the circumstance of 110 kV voltage level and a distance of 1.7 m from power lines.Compared with the UAV line inspection widely used at present,this system will raise the safety and efficiency of inspection operation to a higher level,and achieve the goal of reducing the number of operators from two or above to one.
