[Abstract]:The rapid development of garment industry has brought continuous innovation of sewing equipment. As the most representative sewing equipment, electronic pattern machine has become the research object of this subject. According to the current research situation of the control system of the pattern machine, based on the analysis of the functional characteristics of the 2010 model and the requirements of the user, the paper designs a control software system to meet the needs of the control system, and promotes the design of the product in pattern design and parameter management. Serial communication and other aspects of the ability. In this paper, the embedded platform based on Linux and the ARM9 controller based on S3C2416 are developed, and a control software system based on electronic pattern machine is designed. The main functions and achievements of this paper are as follows: (1) deeply study the computer graphics and related geometric knowledge, and design a pattern rendering algorithm to meet its needs; Secondly, the paper analyzes the DXF general graphic data file format, designs the conversion interface, and realizes the conversion from DXF file to pattern file. Through the design of two aspects, the design ability of the control software system for pattern design is improved. (2) analyze the XML data model and the QtXml module provided by Qt, and design the function of parameter management. According to the parameter content, design the data format, rely on the XML file to save the data, and transform the XML document into the tree structure that the application program can traverse by the DOM parser, design the function interface of the data operation. In order to manage the equipment configuration information efficiently and quickly. (3) study the data transmission protocol and design a serial communication mode to meet the requirements. According to the reliability and real-time requirement of the software system, the serial communication protocol is designed, and the serial communication is designed based on the Linux platform and the serial port programming mode of multithreading and blocking.
