开放式形位误差在线检测上位机SPC软件设计摘要随着我国工业的不断发展，检测技术在装备制造业的地位也日益重要。而作为生产操作指导的有力工具，研制适用于生产线工位需求的小型化、操作简便、检测模式灵活的在线仪器具有十分重要的意义。此次设计的主要意义是检测工业现场加工零件的精度以降低次品率，提高工厂生产效率。通过在上位机设计不同的组态表达式及对应的组态按键，按下不同按键用串口通信指导下位机测量不同的组态，如：圆度、线性度、平行度、最大值最小值。在工件表面的不同位置设置几个电感传感器，先检测标准件的数据，再检测所需工件的数据，将两个数据做差得到的数据值通过信号调理电路传送到ADUC812的AD模块，进行AD转换。同时对单片机进行编程，实现12864液晶显示，矩阵键盘按键控制菜单显示，以及与上位机部分进行串口通讯。通过串口将数据传送到上位机软件，并在上位机对数据进行实时图形显示和SPC（过程统计控制）参数统计，根据所得参数值对工业生产过程进行在线检测和实时控制。实现对生产操作的指导和产品质量的控制。关键词开放式在线检测；传感器组态模式；SPC统计过程控制；数据采集；串口通信；ADUC812SoftwareDesignfortheHostComputerSPCFunctionofOpenFormMode-LineTestingErrorofShapeandPositionAbstractWiththecontinuousdevelopmentofourindustry,thepositionofthedetectiontechnologyintheequipmentmanufacturingindustryisalsoincreasinglyimportant.Asapowerfultoolforproductionoperationguidance,appliedtothedevelopmentoflinestationneedsminiaturization,simpleoperation,detectionmodeflexibleequipmenton-linehasveryimportantsignificance.Thedesignofthemainsignificanceisthedetectionofindustrialprecisionmachiningpartstoreducefailurerate,improvetheproductionefficiency.Thesoftwaredesignofdifferentconfigurationofexpressionandthecorrespondingconfigurationbutton,pressdifferentkeysusingserialcommunicationmachinemeasuringdifferentconfigurationguide,forexample:circulardegree,lineardegree,paralleldegree,minimumandmaximumvalues.Inthesurfaceoftheworkpieceindifferentpositionsetseveralinductancesensor,detectionofstandardpartsofthedata,andthenrequiredtodetecttheworkpiecedata,ThetwodataisobtainedbysubtractingthevalueofthedatathroughthesignalconditioningcircuitistransferredtoADmoduleofADUC812.Atthesametimeprogramonthesinglechip,lightthe12864LCD,controlmatrixkeyboardkeysandcommunicatewiththehostcomputerthroughtheserialport.Throughtheserialporttotransmitdatatothehostcomputersoftware,thehostcomputerfordatarealtimegraphicaldisplayandstatisticsSPCdata,accordingtotheparametervaluesforindustrialproductionprocessforon-linedetectionandreal-timecontrol.Achievetheproductionoperationguidanceandproductqualitycontrol.K
