The invention relates to artificial intelligence and provides a system abnormality detection method, device, equipment and storage medium. The method comprises: respectively inputting the marked log, unmarked log and extended log of the system to be detected into three identical training models in the training model set for training, and outputting the probability distribution of each abnormal level of the three; and then calculating the output of the training model The cross-entropy loss and consistency loss; then predict the abnormal level of the unmarked log and the extended log according to the consistency loss, and iterate the training model set according to the cross-entropy loss until the training model set converges to obtain the log anomaly detection model; finally Detect abnormal logs during system operation through the log anomaly detection model. In addition, the present invention also relates to block chain technology, and its marked log, unmarked log and extended log can be stored in the block chain. By optimizing the model training method, it prevents the model from overfitting and reduces the difficulty of the detection model in detecting abnormal points in the system.

The invention discloses a method for automatic segmentation of ultrasonic breast tumors based on attention-enhanced improved U-shaped network, step (A), constructing an attention-enhanced improved U-shaped network structure for extracting the target features of ultrasonic breast tumors; step (B) ), establish a mixed attention loss function that improves the U-shaped network structure with attention enhancement, and is used to obtain a more accurate network loss value; step (C), improves the U-shaped network structure and the mixed attention loss function according to the attention enhancement, by The network layered training method combining thickness and fineness fine-tunes the network parameters, improves the accuracy of the network parameters, and realizes the rapid positioning and segmentation of the lesion area in the breast ultrasound image. The invention can be used to extract the lesion area of ​​breast ultrasound images, which can effectively improve the accuracy of breast tumor segmentation, assist doctors to quickly and accurately locate the lesion area, reduce the workload of doctors, and alleviate the defects of young doctors' lack of clinical experience. Medicine has very important research value and application prospect.

The invention discloses an electric energy metering device simulation training platform. The electric energy metering device simulation training platform comprises a cabinet, an acquisition terminal, a main three-phase electric energy meter, an auxiliary three-phase electric energy meter, a main meter junction box, an auxiliary meter junction box and terminal blocks. A 220V alternating-current power supply supplies power to the acquisition terminal, the main three-phase electric energy meter and the auxiliary three-phase electric energy meter; the main three-phase electric energy meter and the auxiliary three-phase electric energy meter are respectively connected with the acquisition terminal through a 485 communication interface; the acquisition terminal, the main three-phase electric energy meter, the auxiliary three-phase electric energy meter, the main meter junction box, the auxiliary meter junction box and the terminal blocks are connected to form A-phase, B-phase and C-phase voltage and current circuits. The electric energy metering device simulation training platform has the advantages that actual operation conditions of the onsite electric energy meters and the acquisition terminal are simulated under off-site test room conditions, all work contents of metering and acquisition operations of a substation are covered, requirements on staff training and defect elimination simulation are met, and safety and stability in operation of electrical metering equipment and efficiency in stable acquisition of electric quantity data are improved; further, equipment movement is facilitated owing to wheels mounted at the bottom of the cabinet.

The invention discloses a Wushu arm power training device capable of preventing muscle atrophy. The training device comprise a cement base, wherein upright rods are symmetrically mounted at the top end of the cement base; a suspended cross rod is mounted at the tops of the upright rods; first fixed pulleys are rotatably connected in the middle of the suspended cross rod at equal distances in an embedded manner; a training belt is slidingly connected to the top end of each of the first fixed pulleys; a first handle is hanged at a bending part of each of the training belts; a counterweight blockis slidingly connected to one side of the middle of a counterweight rod, which corresponds to a traction belt. The training device is scientific and reasonable in structure, and safe and convenient to use; the training belts, the traction belt, the first handles, the counterweight rod and the counterweight blocks are arranged, so that the different quantities of counterweight blocks are placed atthe two ends of the counterweight rod, and a user pulls each of the first handles with different arm power. Therefore, the problem that the user has weaker arm power before onset of muscle atrophy issolved. In addition, after the user is trained for a long time, the arm power of the user can be effectively improved, and the muscle atrophy can be effectively prevented.
