实例INCA(变量测量实例功能工具)「inca常用变量」

ETAS通过INCA软件产品，为汽车电子系统的标定、诊断和验证提供灵活的工具
INCA工具用于ECU开发和试验，以及车辆、试验台、工作台或电脑虚拟环境中电子控制系统的验证和标定
在全球范围内，超过35000台用于开发和省擦痕那个项目的装置使用INCA工具
INCA工具具有多种功能，包括计算机上功能模型的预标定、ECU闪存编程、测量数据分析、标定数据管理以及ECU参数的自动优化
生成的标定和测量数据可以进行持续处理和评估
由于PVE测试项目工作中需要实现对INCA的操控以更好的达到实操体验，因此需要运用INCA官方提供的虚拟COM组件incacome.dll进行二次开发，本文展示INCA操控的模块，以供和大家一起探讨、学习交流心得
上位机软件的INCA模块如图：INCA的操控包含：INCA的配置、INCA的启动、INCA初始化硬件配置、进入试验环境、设定参数或启动某些功能、添加变量到INCA、读取测量变量与标定变量、设定标定变量、批量导入INCA变量、批量设定标定变量等
定义部分需要的全局变量，启动INCA，实例化INCA就能打开INCA软件：

private Inca inca;        private Experiment experiment;        private IncaExperimentView experimentView;public void StartInca()        {            this.inca = new Inca();        }

进入试验环境或工作空间：

IncaDataBase incaDataBase = inca.GetCurrentDataBase();OpenDBWrokSpace(incaDataBase);private void OpenDBWrokSpace(IncaDataBase incaDB)        {            HardwareConfiguration myHWC = incaDB.GetActiveHardwareConfiguration();            if (myHWC == null)            {                System.Windows.Forms.MessageBox.Show("获取硬件配置失败
", "提示", MessageBoxButtons.OK, MessageBoxIcon.Error);                return;            }            ExperimentEnvironment myExpEnv = myHWC.GetAssignedExperimentEnvironment();            var success = myExpEnv.SetHardwareConfiguration(myHWC);            //Opens the INCA Experiment assigned to the active workbase            IncaExperimentView myExpEnvView = myExpEnv.OpenExperiment();            GetExperiment();        }private void GetExperiment()        {            if (inca != null && experiment == null)            {                experiment = inca.GetOpenedExperiment();//试验中                experimentView = this.inca.GetOpenedExperimentView();                //init params                var b = this.experiment.IsIncaOnlineExperiment();                IncaOnlineExperiment onlineExperiment = this.experiment as IncaOnlineExperiment;                WorkbaseDevice myDevice = experiment.GetDevice("XCP: 1") as WorkbaseDevice            }        }

读取所有标定变量，并添加到集合：

public List<string> ReadIncaAllCalibrationElement()        {            CalibrationElement[] calibrationElementArray = experiment.GetAllCalibrationElements();            List<string> calist = new List<string>();            foreach (var calElement in calibrationElementArray)            {                calist.Add(calElement.GetName());            }            return calist;        }

读取所有测量变量，并添加到集合：

 public List<string> ReadIncaAllMeasureElement()        {            MeasureElement[] measureElementArray = experiment.GetAllMeasureElements();            List<string> meslist = new List<string>();            foreach (var mElement in measureElementArray)            {                meslist.Add(mElement.GetName());            }            return meslist;        }

启动读取变量值：

public bool StartReadIncaMeasure()        {            if (this.experiment == null)                return false;            OnlineExperiment onlineExperiment = experiment as OnlineExperiment;            return onlineExperiment.StartMeasurement();        }

添加变量到INCA：

public bool AddIncaMeasureElement(string measure)        {            if (this.experiment == null)                return false;            var measureElement = this.experiment.GetMeasureElement(measure);            if (experimentView.OpenViewForMeasureElementWithMaxLabels(measureElement, 1))                return StartReadIncaMeasure();            return false;        }

根据标定变量名称获取标定变量值：

 public string GetCalibrationElementValue(string calibrationElement)        {            try            {                if (experiment == null)                    return "";                var calibElement = experiment.GetCalibrationElement(calibrationElement);                var calibrationData = calibElement.GetValue();                CalibrationScalarData scalarData = calibrationData as CalibrationScalarData;                var arra = scalarData.GetDoublePhysValue();                var type = scalarData.GetPhysType();                var tValue = "";                switch (type)                {                    case "char":                        tValue = scalarData.GetCharPhysValue();                        break;                    case "real64":                        tValue = scalarData.GetDoublePhysValue().ToString();                        break;                    default:                        break;                }                return tValue;            }            catch (Exception ex)            {                return "";            }        }

根据测量变量名称获取测量变量的值：

        public string GetMeasureElementValue(string measureElement)        {            try            {                if (experiment == null)                    return "";                AddIncaMeasureElement(measureElement);                MeasureScalarData measureData = experiment.GetMeasureElement(measureElement).GetValue() as MeasureScalarData;                var type = measureData.GetPhysType();                var tValue = "";                switch (type)                {                    case "char":                        tValue = measureData.GetCharPhysValue();                        break;                    case "real64":                        tValue = measureData.GetDoublePhysValue().ToString();                        break;                    default:                        break;                }                return tValue;            }            catch (Exception ex)            {                return "";            }            finally            {            }        }

设定标定变量的值，标定前一定要切换到WD：

 public bool SetCalibrationElement(string calibrationElement, string setValue)        {            try            {                if (experiment == null)                    return false;                var caliElement = experiment.GetCalibrationElement(calibrationElement);                WorkbaseDevice workDev = caliElement.GetDevice() as WorkbaseDevice;                workDev.SwitchToReferencePage();//切换wd                CalibrationScalarData calibrationData = caliElement.GetValue() as CalibrationScalarData;                var type = calibrationData.GetPhysType();                switch (type)                {                    case "char":                        {                            return calibrationData.SetCharPhysValue(setValue);                        }                    case "real64":                        {                            double val;                            double.TryParse(setValue, out val);                            return calibrationData.SetDoublePhysValue(val);                        }                    default:                        break;                }                return false;            }            catch (Exception ex)            {                return false;            }        }

关闭INCA软件： public bool CloseIncaTool() { return this.inca.CloseTool(); }INCA中还有很多其他功能，可根据自己需要进行二次开发
