Design And Realization Of Tacking Machine Motion Control System Based On Embedded System

With the development of embedded technology and market demanding, people are now paying more attention to the performance of sewing equipments. However, some domestic special sewing equipments, such as embroidery machines, electron tacking machine, which not only bear low cost performance ratio, but also depend on imports mostly, already can't satisfy the market demand. In order to satisfy the need of real-time, precision and speed, a controller of high speed industry tacking machine is developed based on ARM9+Windows CE in the paper.On the hardware design part, first analysis the functional requirements of the system, and select development environment of software and development platform of hardware. We choose a strong real-time operating system-Windows CE as our software development environment and embedded microprocessor S3C2410 as our host controller of the hardware platform. Then made a presentation to overall design of the system, and gives the structure of the system. Then introduced the system in various functional modules, and gives the design diagram. This paragraph focused on the hardware implementation of the main control board, servo electrical module and stepper motor module. In driven design part, complete the driver of main-axis part and stepping motor part by the means of stream driver. And in order to meet requirement of real-time, we adopted multi-threaded and interrupt handling mechanism of Windows CE. In the application software design part, first analysis the workflow of tacking manhine, and focus on software implementation of two main modules:servo electrical module and stepper motor module. And introduce the motion control algorithm, including single axis zero positioning algorithm and multi-axis coordinated control algorithm. By comparing and analyzing several existing algorithms, a more efficient and reliable method of three-axis coordinated motion control was presented. The method has been applied to the systems successfully. This paper also gives the debugging process. First test the individual modules, and based on this, test the system. According to the result of the patterns, it has proved our method has been applied to the system successfully. At last, sumed up the issues in the process of research and development, and prospected the next-step development and research focus of tacking machine.Through the design and realization of system and the analysis of test results, it indicates that the motion control system can satisfy the performance requirements of high-speed tacking machine system. At present, the performance of China-made high-speed industrial tacking machine still lags behind others abroad. The task is to develop one high capability and low cost tacking machine controller. It has a good influence to the tacking machine industry.
