Description

Catenary real-time monitoring system for railway electric power {SYSTEM FOR REAL TIME MONITORING OF CATENARY OF RAILWAY ELECTRIC POWER}

The present invention relates to a real-time monitoring system for railway power on catenary lines.

The catenary of railway electric power is an uncovered copper wire (aka bare copper wire) that contacts the current collector plate of the pantograph to supply the necessary load to the railway car, and is installed at a certain height from the track surface in order to contact the pantograph mounted on the top of the railway car. is installed in

Meanwhile, birds such as magpies have a habit of building nests in high places to avoid natural enemies such as snakes. They build nests not only in trees in the forest, but also on telephone poles and tram tracks that supply electricity to railroad cars. Additionally, wet tree branches or wires that they use to build houses can come in contact with power lines or fall on the roadway, causing short circuits and power outages.

In particular, if a magpie's nest touches a tram line carrying a high-voltage current of 25,000 volts, or if wire, tin foil, or wet tree branches fall, there is a risk of a power outage and even an explosion.

Accordingly, technologies for monitoring the status of such tram lines in real time have been disclosed.

Korean Patent No. 10-2169211 discloses an automatic detection device and method for bird nests on tram tracks that can automatically detect bird nests on tram tracks using image analysis technology.

According to the above patent, images are collected through cameras installed in trams that run every day along the tracks, and the images are analyzed to automatically detect bird nests that exist on the entire track, thereby preventing short circuits in tram tracks caused by bird nests such as magpie nests. Accidents can be prevented, and the patrol inspection manpower and time required to find and remove magpie nests can be significantly reduced.

However, the above technology can only provide information to remove already completed bird nests by monitoring tram lines through the analysis of images taken using cameras installed on operating railroad cars, and can only provide information to remove bird nests for nesting. By failing to effectively prevent access, there was a problem that the nest-building act itself could not be prevented in advance.
