4results about How to "Avoid manual collection" patented technology

This invention provides a transformer sound anomaly detection method based on sample generation and sequence alignment. The method includes: performing frame-by-frame processing on a sampled audio sequence to obtain a time series; dividing the time series into a training set and a test set; using the training set as input samples to train an autoencoder; using the test set as input to the trained autoencoder to output a predicted sequence; and applying delay correction to both the time series in the test set and the predicted sequence to align the test sequence with the predicted sequence; evaluating the error between the test sequence and the predicted sequence to identify the anomalous signal. This avoids the inconvenience of manually collecting and labeling anomalous sound signals. Furthermore, considering the time insensitivity of the autoencoder, a sequence alignment method is proposed to address the potential time delay effect in the autoencoder output.

The utility model relates to the field of automobile precision continuous stamping dies, in particular to a waste cutting device of an automobile precision continuous stamping die. Comprising a base, four hydraulic rods are installed on the upper surface of the base, the output ends of the hydraulic rods are fixedly connected with a machine body, a punching device is installed on the lower surface of the machine body, a cutting structure is arranged at one end of the machine body and comprises two sliding plates, and the two sliding plates are fixedly connected with the machine body; a connecting base is arranged on the side, close to the sliding plate, of the base, inserting rods are slidably connected to the two sides of the connecting base and the two sides of the base, and connecting rods are fixedly connected to the ends, away from the sliding plate, of the inserting rods. The waste cutting-off device of the automobile precise continuous stamping die has the advantages that discharged waste can be conveniently and rapidly cut off when stamping parts are stamped, continuous work can be conducted, and waste cutting-off can be conducted by means of stamping impulsive force.

The invention relates to the technical field of detection equipment, and discloses metal chain tension detection equipment which comprises a workbench, the top of the workbench is fixedly connected with a sliding rail, the top of the sliding rail is fixedly connected with a top plate, the inner wall of the top plate is fixedly connected with a motor, and the output end of the motor is fixedly connected with a lead screw. According to the chain detection device, when the chain detection work is started, the pull rod moves to drive the baffle to move, so that when the lifting plate moves upwards, the bearing capacity of the chain under different loads can be detected, and whether the strength standard of the design requirement is met or not is determined; according to the chain detection device, the situation that the chain is broken due to insufficient strength in use is avoided, meanwhile, the position of the chain can be limited, the chain is prevented from being suddenly bounced off or falling off under the action of pulling force, the chain can be rapidly installed at a proper position, the installation time is shortened, and the detection efficiency is improved.
