备注

随着新冠肺炎疫情的发生,交通管制、设卡布控等防控措施相继实施,为管道线路的日常巡检带来挑战。针对疫情防控下管道巡线人员无法到现场开展巡护的问题,分析现有管道线路感知技术的不足,创建了天空地一体化管道线路智能感知技术体系。根据全面感知、无人感知、实时精准感知、全生命周期感知的感知原则,制定了人工智能技术与管道感知技术相融合的技术路线,设计了天上管道卫星遥感影像智能解译方法、空中基于自动机场的无人机智能巡检方法、地面管道重点区域智能视频方法及地下光纤综合智能感知方法,并对基于自动机场的无人机智能巡检技术开展了现场应用。结果 表明:基于自动机场的无人机智能巡检系统可在无人参与的情况下,实现自动起飞、降落、充电等操作,按照设定的巡检路径、巡检时间进行作业,并可智能识别机械挖掘、人员聚集等威胁事件。新冠肺炎疫情期间,无人机连续飞行80 余架次,识别威胁事件20 余次,为管道巡检人员掌握管道安全状态提供了强有力的技术支持。(图5,参[26]

With the outbreak of the epidemic of COVID-19, traffic control, setting of check posts and other control measures have been implemented and posed challenges to the routine inspection of the pipeline. Regarding the issue that pipeline inspection personnel cannot complete the on-site inspection and maintenance under epidemic prevention and control situation, the space-air-ground integrated pipeline intelligent perception technology system was proposed through analyzing the deficiencies of the existing pipeline perception technology. According to the principles of comprehensive perception, unmanned perception, real-time accurate perception and full life cycle perception, the technical route integrating artificial intelligence technology and pipeline perception technology was established. The intelligent interpretation method for satellite remote perception images of pipelines at space level, the unmanned aerial vehicle intelligent inspection method based on automatic airport in air, as well as the intelligent video method for key pipeline areas aboveground and the comprehensive intelligent perception method of underground optical fibers at ground level were designed. The field application of unmanned aerial vehicle(UAV) intelligent inspection technology based on automatic airport was explored. Field tests and applications show that the unmanned aerial vehicle intelligent inspection system based on automatic airport enables the automatic take-off, landing, charging and other operations without the human participation, and the operations following the set inspection path and inspection time. Besides, it can intelligently recognize threat events such as mechanical excavation and personnel gathering. During the epidemic of COVID-19, the UAV flew for more than 80 sorties and recognized more than 20 threats. This shows that it can provide strong technical support for pipeline inspection personnel to master the safety status of pipelines. (5 Figures, 26 References)
