Research And Application Of Servo Controller In Slubby Yarn Device Based On ARM

In the domestic market, the prevalent spinning equipments are ring spinners based on Programming Logic Controller (PLC), which mainly include Human Machine Interface (HMI), PLC, driver and servo motor. But the whole system is expensive for small corporations. And it's difficult to form competition compared to others. So developing totally digital spinning apparatus with the same or alike functions, which is also low-cost, is urgent for many application companys.According to the producing demand of the servo controller, sereval modules have been designed, which mainly consist of extended memory module, displaying interface module, serial communication module and counter module. Windows CE has been transplanted into ARM. The developments of boot loader and OEM Adaption Layer have completed, and the stream interface driver of main modules in Windows CE has also been developed. Finally the application programming for producing slubby yarn has been developed. The controller has function of both PLC and HMI. It has function of process controlling and function of displaying and inputting of parameters.Through the measurement of every part of slubby yarn produced, comparison to the corresponding parameters inputted through touch screen, slubby yarn weighing and other methods, the result is sastisfactory. The advantages including easy operation, high control accuracy, low cost and so on of the device make the device have high popularization value and use value.
