Electric quantity data that electric quantity detection subsystem gathered, the humidity data that dehumidification subsystem gathered in the cabinet, the first temperature data of play that contact temperature measurement subsystem gathered, the ambient temperature humidity data that environmental temperature measurement humidity measurement subsystem gathered, SF6 and the concentration data of oxygen that SF6 and oxygen detection subsystem gathered, the water logging that water logging detection subsystem gathered, the transformer temperature data that transformer temperature detection subsystem gathered, smoke concentration data and the temperature data that fire detection subsystem gathered do machine learning model's real-time input to whether the relevant subsystem of real-time output appears unusually on fortune dimension platform, and start the unusual abnormal behavior of correcting the mechanism automatic correction of anomaly. For example, when the ambient temperature is determined to be too high, the air conditioner is automatically turned on, and when the ambient humidity is determined to be too high, the dehumidification function is automatically turned on, and the like. In the power distribution operation and maintenance system, the damage levels of flooding and fire are highest, in order to prevent errors possibly caused by judging only by using sensor data, video data acquired by a video subsystem is input into a svm model specially used for processing the video data to judge whether a water immersion phenomenon and a fire phenomenon occur or not, the abnormal type and the damage level occurring are displayed on an operation and maintenance platform in real time, operation and maintenance personnel are notified, under the condition that the abnormal damage level is lower, the operation and maintenance personnel determine whether to start a drainage system and/or a fire extinguishing program or not, and under the condition that the abnormal damage level is higher, the drainage system and/or the fire extinguishing program is automatically started. The method for judging whether the water logging phenomenon and the fire disaster phenomenon occur specifically comprises the following steps: (1) acquiring a video training set, marking each frame in the training set, and marking the frame with the flooding phenomenon as a vector according to different flooding degrees by using a frame marking toolWhereinw₁，w₂，w₃，w₄Respectively representing the probability that the flooding phenomenon is very unobvious, the probability that the flooding phenomenon is obvious and the probability that the flooding phenomenon is very obvious; marking the frame with fire phenomenon as vector according to different fire degree by using frame marking toolWhereinf₁，f₂，f₃，f₄Respectively showing the probability of fire phenomena being very unobvious, the probability of fire phenomena being obvious and the probability of fire phenomena being very obvious; (2) training an s upsilom model by using the marked data, training the s upsilom model by using the marked data, and marking a vector of each frameInputting the frame into an s upsilom model, outputting probability vectors of water immersion and fire of each frame, and inputting each frame in a video into an s upsilom classifier to obtain a characteristic value vector of the frameWherein t is₁，t₂Respectively representing the probability of the water logging phenomenon and the probability of the fire phenomenon of the frame, and further obtaining a characteristic matrix corresponding to the videom represents the number of frames of the video,respectively outputting a feature vector of each frame for the upsilom; (3) if p is₁＜(t_i)₁＜p₂，p₁＜(t_i-k)₁＜p₂If so, judging the water immersion danger level to be lower; if (t)_i)₁≥p₂，(t_i-k)₁≥p₂If so, judging that the water immersion hazard grade is higher; if q is₁＜(t_i)₂＜q₂，q₁＜(t_i-k)₂＜q₂If so, judging the fire hazard level to be lower; if (t)_i)₂≥q₂，(t_i-k)₂≥q₂Judging the fire hazard grade to be higher; wherein i > k, p₁，p₂，q₁，q₂Is a preset probability, k is an arbitrary value in (0, s), s is a preset window size, and i is a position of an ith frame in the video. For example: p is to be₁，p₂，q₁，q₂The video frame rate is 24fps, if the probability of occurrence of the water logging phenomenon is more than or equal to 0.7 in continuous 10 seconds and the probability of occurrence of the fire disaster phenomenon is more than or equal to 0.6 in continuous ten seconds, the drainage system and/or the fire extinguishing program is automatically started.
