目前输电线路大量配置前端感知装置，种类多、版本迭代快、可靠性参差不齐，如何高效实现人机协同，最大限度提高输电线路巡检效率成为困扰一线班组的难题。对此，通过设计基于人机协同的立体巡检系统，搭建了感知层装置可信度评估模型，开发了五种典型应用场景，实现了输电线路巡检多源数据融通、工作场景构建、人机协同配合、巡检策略优化、应急处置及时的目标。实践结果表明，输电线路立体巡检系统可以有效降低生产成本，提升人员和设备安全水平。

Transmission lines are now copiously equipped with front-end sensors characterized by a great variety,fast version iteration,and varying reliability levels,and how to efficiently achieve human-machine collaboration and maximize the efficiency of transmission line inspection has become a thorny problem plaguing the front-line team. In this regard,through the design of a three-dimensional inspection system based on human-machine collaboration,a perception layer device credibility assessment model is built,and five typical application scenarios are developed to achieve the goals of transmission line inspection multi-source data integration,work scenario construction,humanmachine collaboration,inspection strategy optimization,and timely emergency handling. The practice results show that the three-dimensional transmission line inspection system can effectively lower production costs and improve personnel and equipment safety levels.
