Abstract: A direct-current electric energy generation circuit for new energy application. When an input alternating-current voltage (Vin) is in a high-voltage range, an output voltage of a rectifier circuit (1) is reduced to obtain an output voltage (Vout) of the direct-current electric energy generation circuit; when the input alternating-current voltage (Vin) is in a low-voltage range, the output voltage of the rectifier circuit (1) is directly taken as the output voltage (Vout) of the direct-current electric energy generation circuit, so that the output voltage (Vout) of the AC-DC voltage is close to each other when the input alternating-current voltage (Vin) is in the high-voltage range and the low-voltage range. The output voltage range of the direct-current electric energy generation circuit is reduced, the optimization and selection of post-stage power devices are facilitated, and the direct-current electric energy generation circuit has obvious advantages especially in the aspect of new energy application.

Abstract: Disclosed is an online detection method for circular weft knitting horizontal stripe defects based on a grayscale gradient method, belonging to the technical field of textile product detection. The method provides a defect detection and positioning method based on a grayscale gradient method. Before a new product is detected, only a model needs to be trained to acquire feature images of horizontal stripe defects of different organization types and different fabric densities, and subsequently, detection is performed directly. Not only can the defects be quickly and accurately identified, but triangular positions causing the horizontal stripe defects can also be calculated according to the number of photographed images between the feature images and mark images, horizontal columns on which marks in the mark images are located, horizontal columns on which the defects in the defect images are located, and machine operating parameters. In addition, a defect detection apparatus required in the present application can be modified from an original circular knitting machine, thereby saving on detection costs.
