This application discloses a loom control method, a loom control cabinet, and a loom, belonging to the field of loom control technology. The method includes: acquiring user-defined information; obtaining process control information corresponding to the user-defined information based on a process control library; driving the movement of each heald frame according to the shedding control information; detecting the motion state information of the shedding mechanism in real time; using an adaptive learning model to obtain process adjustment information based on the motion state information; and adjusting the motion state of each heald frame according to the shedding adjustment information. This application solves the problems of inconvenience and reduced production efficiency when changing fabric patterns or types in a loom, achieving the effect of process control of the shedding mechanism and real-time adjustment of the motion state of each heald frame for different fabric patterns or types.

To provide an image generation method capable of easily removing a trouble which may be inherent in a fabric pattern image, a program, and an image generation device.SOLUTION: There is provided an image processing method including an output pattern image generation step. The output pattern image generation step generates an output pattern image from a fabric pattern image by correcting the fabric pattern image using a loss function. Each pixel value of the fabric pattern image is binarized to a first or a second pixel value so that a hierarchical relationship between warp and weft is identified. A value of the loss function is calculated per pixel. In correction processing, a pixel in which the value of the loss function decreases before and after correction serves as a pixel to be corrected. A pixel value of the pixel to be corrected is reversed from one of the first and second pixel values to the other pixel value.SELECTED DRAWING: Figure 1

The application relates to a jacquard opening transmission system of a loom and a design method thereof, and belongs to the technical field of jacquard opening of looms. The transmission system comprises a main shaft, a crank rocker mechanism, a parallel four-bar linkage mechanism and two groups of parallel multi-link mechanisms. The multi-link mechanism comprises a rocker slider mechanism. The crank rocker mechanism drives the multi-link mechanism to move, so that vertical reciprocating motion and rotary motion of a lifting knife frame are realized to form an opening. The main shaft can be driven by a servo motor to realize variable speed input. The design method combines rigid body guidance and quick return characteristics. Design equations, transmission function models and evaluation models of the rocker slider mechanism and the crank rocker mechanism are constructed, and the size of the mechanism is optimized. The application has the advantages of low gravity center, simple motion range adjustment, high transmission efficiency, smooth motion and the like, is suitable for looms with different widths, and can improve weaving quality.

Conventionally, validating a configured jacquard card is manual, difficult and time-consuming process. Automated techniques require complex and costly hardware setup. Embodiments of present disclosure provide a method and system to verify and reconfigure design values of reconfigurable jacquard cards. It obtains a design from user and generates reference images of patterns required to weave the design. The user then configures the jacquard card based on the reference images and scans them after configuration. Patterns in the scanned images are validated against the reference images by identifying position of first top left hole and iteratively verifying the remaining holes by traversing one hole at a time and comparing its pixel value with that of the reference image. If the user has to create a new design using the same set of configured jacquard cards, order of the cards to be used for reconfiguring the new design with minimal cost is suggested.
