【摘要】 架空电缆巡检对电力系统的维护具有重要的意义。Petri网是一种通过图形化的方式描述复杂系统的数学模型，具备非常丰富的分析方法。文章对架空电缆无人机巡检进行Petri建模分析后，在此基础上增加红外感应设备，借助物联网技术，添加库所变迁，建立优化后的架空电缆无人机巡检的Petri网模型。并用PIPE软件对优化后的巡检方式进行建模分析，验证了该巡检的合理性、有效性。更多还原

【Abstract】 Overhead cable inspection is of great significance for the maintenance of the power system. Petri network is a mathematical model that graphically describes complex systems with a very rich range of analytical methods. In this paper, after the Petri modeling and analysis of the overhead cable UAV inspection, the infrared sensing device is added on this basis, and with the help of the Internet of Things technology, the change of the library is added, and the Petri network model of the optimized overhead cable UAV inspection is established. The optimized inspection method is modeled and analyzed by PIPE software, which verifies the rationality and effectiveness of the inspection.更多还原
