Intelligent video online monitoring and evaluation system for foreign body intrusion in transmission lines

Abstract

The invention provides a power-transmission-line foreign-matter-invasion intelligent-video on-line monitoring evaluation system and belongs to the intelligent power grid technology field. The system comprises a video image acquisition module, a data analysis processing module and a communication module. The video image acquisition module collects video images of a power transmission line and sends to the data analysis processing module so as to analyze a motion trend of a foreign matter relative to the power transmission line and classify the foreign matter. Based on that, early warning or alarm is performed on the invasive foreign matter. Simultaneously, historical data is formed and a power-transmission-line foreign-matter invasion environment is evaluated and analyzed. The system possesses power transmission line foreign matter invasion early warning and alarm functions; the foreign-matter invasion environment is evaluated and generation of power transmission line potential safety hazards caused by the foreign matter invasion is effectively reduced; simultaneously interferences of icing and snow coating, waving and sag changes are eliminated and accuracy of a monitoring result is increased. The system possesses advantages that an intelligent degree is high; cost is low; installation and maintenance are convenient and so on. The system can be widely applied to power-transmission-line foreign-matter-invasion intelligent on-line monitoring.

Description

technical field [0001] The invention provides an intelligent video online monitoring and evaluation system for foreign matter intrusion on transmission lines, which belongs to the technical field of smart grids. Background technique [0002] Transmission lines work in the wild all year round, and also cross complex environments such as urban economic belts, roads, and bridges. During urban construction, large mechanical vehicles often invade the protection area of ​​transmission lines, and accidents such as line short circuit, tripping, and power outages occur frequently due to mechanical contact or insufficient safety distance between machinery and transmission lines resulting in discharge. In addition, the invasion of foreign matter caused by natural factors such as birds flying over, trees falling, and branches falling will also endanger the safe and stable operation of transmission lines. Therefore, it is necessary to monitor and evaluate the intrusion of foreign object...

Problems solved by technology

[0003] At present, with the rapid development of intelligent video technology, there is also a technology that uses video and images to monitor foreign matter intrusion on transmission lines. The Chinese patent "A Video Monitoring System for Foreign Object Invasion on High-Voltage Transmission Lines" (Application No.: 201110385906.6 ), and the Chinese patent "A Method for Detecting Foreign Objects Intruded on High-Voltage Lines" (Application No.: 201410484914.X), both use image processing to monitor intruded foreign objects on transmission lines, but both lack the distinction of the types of intruded foreign objects, As well as the assessment of the environment for foreign matter intrusion, it is impossible to accurately assess the harm of foreign matter intrusion to transmission lines; nor does it eliminate the impact of transmission lines on the monitoring of foreign matter intrusion on transmission lines due to ice and snow, galloping, and sag changes. There are many defects that need to be improved urgently
