油气长输管道事故发生后,需要及时了解事故现场情况,掌握周边环境信息,建立应急通讯等,而管道所处地理环境复杂、事故定位及处置难度高、进场道路不便、现场通信条件差等特点,严重制约了应急抢修工作的开展。无人机具备高空、远距离、快速、自行作业的能力,通过搭载不同设备、配合不同技术,可应用于管道泄漏、燃爆、溢油等事故判断,并协助开展应急抢修作业。通过分析各种无人机技术特点,结合国内外行业内无人机应用现状,围绕油气管道应急场景,明确了无人机技术在油气管道应急场景中可实现的功能,并从远程图传和图像合成方面开展了无人机应急系统构建及实践。研究结果有助于提升企业应急抢修和指挥决策能力。

Immediately after the occurance of an oil and gas pipeline incident, it is necessary to understand the actual site situations, grasp the surrounding environment information, and establish emergency communication in a timely manner. However, the complex geographical environment along the pipeline route, the extreme difficulty in locating the incident site and disposition of the situation, inconvenient road access and the poor communication infrastructure at the site have imposed major limitation to the emergency repair work. The unmanned aerial vehicle (UAV) has the ability of high altitude, long flight distance, high speed and can operate independently. By carrying different equipment and equipped with different technologies, UAV can be used to assess pipeline leakage, fire and explosion, oil spill and other incidents, and assist in implementing emergency repair operations. By analyzing the characteristics of various UAV technologies and combining the current UAV application experience at home and abroad, the achievable functions of UAV technology in oil and gas pipeline emergency were defined focusing on the oil and gas pipeline emergency response. UAV based emergency response system was developed based on the aspects of remote image transmission and image synthesis. The study results presented in this paper will help enterprises to enhance their emergency response and management, emergency repair and decision-making capabilities.
