Abstract: This paper analysed and designed the pattern format of the electro-bar-tacking machine,including the storage format and format of the sewing-frame.Introduced the conversion process of the user coordinates and the machinery coordinates when sewing the pattern.Based on the characteristics of the servo motor and the step motor,put forward a controlling method of the sewing pattern control system using the DSP and the uC/OS-II as controlling platform.Researching results has been applied and verified in the intelligent electro-bar-tacking machine.The application results show that the control systems is acurate,reliable and practical.
