Method and system for transmission line cable duct obstacle clearing based on video visualization

Abstract

The invention discloses a method and a system for transmission line cable duct obstacle clearing based on video visualization. The method comprises the steps that: workers send related devices to proper positions at a blocking position; a checking device collects image data in a duct and transmits the data to a control center; the control center constructs a scale space and an image pyramid for the image data, performs positioning for a local extreme point of a differential pyramid, performs data comparison and analysis to determine the blocking condition in the pipeline of the duct and outputs and displays the severity of the blocking of the duct; an obstacle clearing device is started to perform cleaning of the pipeline of the duct and regulates the cleaning force according to the severity of the blocking; and the checking device and the obstacle clearing device in the duct are controlled to perform alternate work according to set programs and time parameters until the blocking in the duct is completely removed, and the checking device and the obstacle clearing device is controlled to be taken back. The method and the system for transmission line cable duct obstacle clearing based on video visualization employ a scientific method to effectively solve the cable duct blocking problem so as to greatly improve the working efficiency.

Description

technical field [0001] The invention relates to the fields of pipeline obstacle removal technology and electric power transmission technology, in particular to a video visualization-based cable pipe removal method and system for power transmission lines. Background technique [0002] In the process of laying cable pipes, the situation that the pipes are blocked and the cables cannot pass through is the most serious and troublesome problem. Power cables are laid through cable ducts, and some problems are gradually exposed. The most difficult to solve is that the cables cannot pass due to the blockage of the ducts. Due to the large amount of sediment at the construction site, rain and accumulated water will cause the sediment to flow into the pipeline and block the pipeline for a long time, especially when the backup pipe is used for pipe jacking across rivers and roads. At the same time, some cable ducts that have been running for a long time may be blocked by foreign matter...

Problems solved by technology

[0004] The object of the present invention is to provide a method and system for clearing obstacles of cable pipes in transmission lines based on video visualization, so as to solve the problem that the prior art proposed in the above-mentioned background technology cannot exactly know the specifics of the blockage when clearing the pipes. The situation, the method is not scientific enough, which leads to the problem of poor work efficiency
