Study Of Visualized Data Processing System For Computerized Flat Knitting Machine Based On Embedded System

Computerized flat knitting machine(CFKM) is a kind of high-technology knitting equipment,which integrates computer science,mechatronic technology and knitting technics.Visualized data processing system is the important component of CFKM system.The visualized data processing system for CFKM is in charge of managing and monitoring the whole knitting system.It sends the processed data to slave-computer implement system by CAN bus.At the same time,it processes the real-time data which collected by the slave-computer,and displays them in the multi-menu,so as to realize the well readable man-machine interaction.The development history of CFKM and the current research situation of embedded system are introduced in the beginning of this thesis.Based on the analysis of hierarchic control structure of the CFKM system,an idea which applies embedded technology to the CFKM system is put forward.The thesis also anatomized the structure of data information of the CFKM,carefully researched the method of the data processing and then summarized the functions of visualization.Through the functional and structural analysis of the visualized data processing system for CFKM, design procedure and principle of the system are proposed.In contrast with the typically conventional design,the method based on a 32-bit embedded microprocessor ARM and real-time operating systemμC/OS-Ⅱis proposed.This method can make full use of the high performance of ARM,the excellent real-time character and transplantable nature ofμC/OS-Ⅱ.Considering the end-user operation convenience,the Human Machine Interface(HMI) characteristics and the embedded system actual performance,MiniGUI which is little size Graphics User Interface(GUI) support system is used to develop HMI.Both hardware and software of the system functional modules are dissertated by using modularization theory.The key arithmetic and data structure are discussed.In order to make sure that the system work steadily in different situations,the reliability technic are also expatiated.Finally,some sweater with different patterns are knitted used the CFKM with visualized data processing system.The problems which emerged in knitting process and debugging results are analyzed.In the end,not only the conclusions of this thesis are summarized,but also the future research work is sketched out.The main innovation of this thesis focused on the CFKM supervisory system. Simultaneously,the visualized data processing system for CFKM based on embedded technology is designed.Practical application shows that the system can reach anticipative functions with high real time quality and good stability.The thesis also discussed the further study on the visualized data processing system for CFKM.
