[0002] Under existing technical conditions, the controller of the quilting equipment is an embedded system based on PLC or microcontroller. The operation sequence is set according to a certain production process to complete the quilting task of fabrics such as quilts. In order to cooperate with the operation of the quilting machine, manual assistance is required. Taking the need for needle quilting and embroidery of decorations on general clothing fabrics as an example, the plush decorations that need needle quilting can only be pre-processed by placing the pattern based on the operator's feeling or experience. After the pre-processed pattern, the decoration is needle quilted and composited to the fabric through manual tools. If the embroidery process is performed on the basis of the needle quilting process, the fabric after needle quilting needs to be fixed to the embroidery machine, and then the embroidery pattern is sewn to the required position with the embroidery machine. The fabric made with such a structure will have the following shortcomings:
