输电线路视频图像识别管理系统

研究输电线路的监测、预警技术,对预防和减少输电线路事故的发生是十分必要的。据此,研制了一种输电线路视频图像识别管理系统。该系统包括输电线路远程监控、故障识别以及信息管理3个功能模块。其中故障识别模块采用图像处理技术,实现了对导线覆冰厚度计算和舞动幅度计算的功能,并且各功能根据其识别对象的关联性相互协调工作。信息管理功能模块以数据库为支撑,可以实现对设备信息、报警信息、微气象信息以及识别结果的管理。此外,系统还将特定的微气象参数作为启动覆冰和舞动识别计算子程序的判定条件,一旦监测地点的微气象条件达到启动条件,则自行启动相应的识别程序,大大提高了系统的可靠性与工作效率。

Video and Image Identification Management System for Transmission Lines

A video and image identification management system for transmission lines is developed and implemented in this paper. The system has three modules, including remote monitoring module, fault identification module and information management module. The image processing technology is used in the fault identification module to realize two functions of ice thickness calculation and conductor galloping amplitude calculation. Different functions work in a coordinated way according to the identified faults. The information management module, which is based on the database, can manage the device information, alarm information and micro-meteorological information as well as identification results. In addition, the system sets certain micro-meteorological parameters as conditions to call the identification subprogram. Once the micro-meteorological conditions of the monitored sites reach the conditions, the identification program will be started, greatly improving the reliability and efficiency of the system.
