Research On Image Positioning System Of Commutator Generator Scraping Groove Edge Rounding Device Based On S3C2440A

Orientate the phenomenon of commutator surface deteriorated working status,it needs repairing operation of scraping groove,edge rounding and others.Traditional repairing procedure adopts artificial processing,but it is low efficient,large workload,low processing accuracy and high scrap rate,in recent years,though appeared machine tool,however,its processing and positioning accuracy cannot meet requirement.Paper melted single chip technology,image acquisition technology,image processing techniques,AC servo technology,developed a set of image positioning system of generator commutator Scraping groove edge rounding device,for realizing rapid check to processing position and accurate positioning,and then come true processing automation,improve repairing and processing efficiency to commutator which has important significance.Paper combine with current status of positioning technology of generator commutator scraping groove edge rounding device,analyze its advantages and disadvantages,and then propose a design plan for image positioning system which based on S3C2440 A generator commutator scraping groove edge rounding device.Firstly,make sure the general structure of the system and working principle and ensure positioning calculation.Secondly,it designed principle image of every parts of S3C2440 A single chip in the system,decided hardware devices of generator commutator scraping groove edge rounding device,according to the current conditions and functions which the system needs to realize,it chooses some unite model like CCD camera,touch screen,display,servo driver and servo motor which used in the system,introduced design principle of PCB circuit board in the system.On this basis,utilize JTAG downloader as development tool,established software platform for the system,transplanted Linux operation system,and compile relevant procedure code of functional model according to S3C244 A firmware library,realized USB driver,touch screen driver,servo driver and other bottom driver,allocate task and finish man-machine interface development of the system.At last,debug and try operation for software and hardware of generator commutator scraping groove edge rounding device,record and process experiment data,analyze the cause of mistake,proposed suggestion in decreasing mistake and proved availability of system.Paper researched part of theory,basis and enlightenment provided by generator commutator scraping groove edge rounding device for realizing accuracy and batch processing of the commutator.
