基于光电编码器技术的脉冲信号校准装置研制 Abstract Thedevelopmentofapulsesignalcalibrationdevicebasedonphotoelectricencodertechnologyisstudiedinthispaper.Thisdeviceismainlyusedtocalibratethepulsesignalofphotoelectricencodersandachieveshigh-precisioncalibrationthroughthecomprehensiveuseofelectroniccircuit,controlalgorithm,andsoftwareprogramming.Thedesignofthepulsesignalcalibrationdeviceispresentedindetail,includingthehardwarecircuit,softwareprogramming,andtestresults.Theexperimentalresultsshowthatthepulsesignalcalibrationdevicebasedonphotoelectricencodertechnologyisaneffectiveandreliablemethodforpulsesignalcalibration. 1.Introduction PhotoelectricencodertechnologyiswidelyusedinthefieldofCNCmachines,robots,andotherprecisionmechanicalequipment.Thequalityoftheoutputofthephotoelectricencoderisessentialfortheaccuracyofthesystem.However,thereisacertaindeviationinthepulsesignaloutputbythephotoelectricencoder,whichaffectstheaccuracyofthesystem.Therefore,itisnecessarytocalibratethepulsesignalofthephotoelectricencoder,improvetheaccuracyofthesystem,andensurethestabilityandreliabilityofthesystem. Atpresent,thecalibrationmethodsforpulsesignalsofphotoelectricencodersmainlyincludemanualcalibrationandautomaticcalibration.Themanualcalibrationmethodissimpleandeasytooperate,butthecalibrationaccuracyislow,anditisdifficulttocalibratecomplexsignals.Automaticcalibrationmethods,suchaspulsesignalcalibratorsbasedonDSPtechnologyandmicrocontrollers,canachievehigh-precisioncalibration,butthecomplexityofthehardwareandsoftwaresystemgreatlyincreasesthecostanddifficultyofoperation. Therefore,thispaperproposesanewmethodofpulsesignalcalibrationbasedonphotoelectricencodertechnology.Bycomprehensivelyutilizingelectroniccircuit,controlalgorithm,andsoftwareprogramming,ahighlypreciseandreliablepulsesignalcalibrationdeviceisdeveloped,whicheffectivelysolvestheproblemsoflowcalibrationaccuracyandcomplexoperation. 2.DesignandImplementation 2.1HardwareDesign Thepulsesignalcalibrationdeviceismainlycomposedofasignalinputmodule,anFPGAce
