Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of intelligent monitoring of substations, and in particular to a modular intelligent monitoring terminal for substations based on Dianhong. Background Art
[0002] With the advancement of power equipment technology, smart substation technology has been significantly developed, which has prompted the renewal of substation design concepts and the development of substation design towards prefabricated modularization. Substation patrol monitoring equipment is the most widely used intelligent terminal in smart substations. Its design, production and manufacturing are all integrated. In the case of camera damage, the maintenance method adopted is to replace the whole camera. In addition, patrol monitoring equipment lacks built-in self-checking algorithms, which is prone to abnormal situations that affect patrol monitoring without faults, affecting the normal operation of patrol monitoring.
[0003] Video detection algorithms mainly analyze image frames in video sequences and use computer vision algorithms to identify and locate target objects in images. The core principle of this technology is to combine deep learning models, especially convolutional neural networks (CNNs), to extract image features and use these features to identify the location and category of target objects. In this process, the algorithm learns the visual attributes of the target, such as shape, texture, and color, and can stably detect targets under different environments and lighting conditions. In addition, in order to process the temporal information in the video, recurrent neural networks (RNNs) or long short-term memory networks (LSTMs) are usually incorporated to consider the dynamic changes of targets in the time dimension. Overall, video object detection technology emphasizes accurate and real-time identification and tracking of targets in continuous image frames, thereby achieving a deep understanding of the video content. It is a solution to the problem of how to locate and identify targets that appear in each video. Compared with image object detection, video detection has the characteristics of high redundancy.
