Electric power emergency command system

The invention belongs to the field of emergency command, and discloses an electric power emergency command system which comprises an image recognition device. The image recognition device comprises an image noise reduction module; the image noise reduction module comprises a noise reduction unit, a calculation unit and a merging unit; the noise reduction unit is used for performing noise reduction on the aerial image of the affected area by adopting various types of noise reduction algorithms to obtain a plurality of processed images; the calculation unit is used for respectively acquiring the merging proportion of each processed image by adopting a particle swarm algorithm; and the merging unit is used for merging the processed images based on the merging proportion to obtain a noise-reduced image. According to the invention, the quality of the obtained noise-reduced image can be further improved, more accurate disaster conditions can be obtained, and the total time required for overall recovery of power sup
