Extra-high voltage converter station screen cabinet pressing plate monitoring and reflection interference removing network and method

Abstract

The invention discloses an extra-high voltage converter station screen cabinet pressing plate monitoring reflection interference removing network and method, the extra-high voltage converter station screen cabinet pressing plate monitoring reflection interference removing network comprises a plurality of sequentially cascaded encoders and a plurality of sequentially cascaded decoders, each encoder comprises two residual error blocks and a WRNL block which are sequentially connected, each decoder comprises a convolution layer, two residual error blocks and a WRNL block which are sequentially connected, the convolutional layer is connected with an SE block, an upper-level output result fused at the input end of the current decoder and an output result of each encoder are input into the SE block in the current decoder, the SE block adjusts the number of channels through the convolutional layer and then inputs the result into a residual block in the current decoder, an image with reflection interference is input into the first-level encoder, and the second-level encoder is connected with the second-level encoder. The last-stage decoder outputs a picture of which the reflection interference is removed; the method has the advantages that the problem that partial areas of the acquired images are difficult to monitor due to light reflection of the surface glass of the screen cabinet in the panoramic monitoring process of the extra-high-voltage direct-current converter station equipment is solved.

Description

technical field [0001] The invention relates to the field of distributed data processing on the edge side of a lightweight artificial intelligence UHV DC protection system, and more specifically relates to a monitoring anti-reflection interference network for a panel cabinet pressure plate of an UHV converter station. Background technique [0002] Sometimes the protection device of UHV converter station should act, but the device itself does not act. Before there was no monitoring method, the on-site operators did not know this situation. After the subsequent installation of monitoring facilities, due to the experience of the operators, Subjective factors such as responsibility will lead to missed inspections. Therefore, video analysis technology is now used to assist operators in judging the actions of protective devices. [0003] The state signal parameters applicable to the core links of UHV DC protection that need to be monitored by the UHV converter station protection d...

Problems solved by technology

[0006] However, in the current video inspection process of converter station equipment, some specific scenes are affected by reflected light, and the collected images will show a large area of ​​reflection, which affects the effect of image information processing

Although some scenarios can be solved by changing the orientation of the camera, in the practice of monitoring the screen cabinet of the secondary equipment, there is always the problem that some areas of the collected images are difficult to monitor due to the reflection of the glass on the surface of the screen cabinet (such as figure 1 input image), which largely affects subsequent machine vision tasks such as target detection and semantic segmentation.

In severe cases, the reflection interference area may even cover the entire area to be detected, making the task impossible to complete or interrupted. This is also an unresolved problem in the research on the panoramic monitoring of UHV DC converter station equipment
