The Improvement And Code Optimization Of Pattern Information Processing And Human Machine Interface For Ⅰ Embroidery Machine Controller

The industrial embroidery machine is highly automatic equipment entailing a high level of efficiency.This type of embroidering machine was maturing under the aid of application and development of microelectronics, computer technology and precision mechanisms. Research and development of I industrial embroidery machine controller based on ARM7 andμC/OS -Ⅱachieved initial success.The paper realized and improved several important modules for industrial embroidery machine based on the confirmation of the system's hardware and software structure including pattern information processing, USB host,flash file system and human machine interface.This topic focused on pattern information processing, the creation of file system, the implementation and improvement of human machine interface for the industrial embroidery machine based on the platforms of ARM7 andμC/OS -Ⅱ.The paper analyzed the composition and the working principle of industrial embroidery machine.It researched the control system solution based on the functional requirements.It introduced the design of pattern file. And after the analysis and compare of several pattern formats prevalent in the world such as DST, DSB and DSZ, this paper designed the customized SYT pattern for these pattern formats without the whole embroidery information and to be compatible of these pattern formats. And the paper researched in the transformation between the prevalent pattern format and the SYT pattern format.The system used ISP1160 as the USB Host controller.The paper analyzed the the principle of embedded USB Host and the realization with the software and hardware.To manage the pattern files in the flash memory effectively, it established a FLASH file system in the NOR FLASH memory.For the characteristics of FLASH memory and the shortcoming of general FAT file system, it established and improved FAT16 file system based on the reliability, wear leveling and sector management.And the design improved the reliability and optimized the performance.At last it realized the transformation of pattern files between FLASH memory and external storage device.The paper analyzed the hardware design of human-machine interface. It designed a customized GUI module and analyzed the realization of the GUI at all levels.It researched the human machine interface based onμC/OS operating sysrem.And against the problems in the development, it proposed the solutions. For practical application, it analyzed the methods of code optimization. In order to make better use of resources, it analyzed the programe solidifination.In this paper, the design has been fully verified and it has been runing stable in the testing.And the function of the system was easy to extend and maintain.
