Research on Power Security Control Technology Based on Multimode Data Fusion

Power grid operation, equipment maintenance, construction and other power grid field operations, the task is heavy, many points and wide. There are many dangerous factors in the process of power grid operation, including human factors, environmental factors, equipment factors, management factors and other influencing factors. Aiming at the problems of single mode and complex factor, a multi-mode fusion method is proposed. Based on the operation ticket mechanism in the "two votes and three systems" of the power system, under the supervision of the original traditional IP layout and control ball, various influencing factors on the site are collected as comprehensively as possible combined with sensors such as blood oxygen, gas concentration, tension, pressure and inclination Angle, and the information characteristics feedback from these factors are utilized across modes. Multi-level fusion method is adopted to fuse the text features extracted by BERT and the image features extracted by Faster R-CNN at an early stage, which improves the normalization of the operation process. By making decision fusion of image features and sensor features extracted by LSTM, the alarm of potential hazards is advanced. Under the multi-mode integration, the average level of overall risk prevention and control on the job site has been improved.
