在工业信息化行业,少不了生产可视化的模块,其中应用最多的是采用LED屏的方式,通过软件控制屏幕展示相关的生产计划完成状态,工位的状态,产线的运行状态,以及相关自动化设备的状态等,这就要求通信实时性,准确性。LED屏控制核心在于控制卡目前市场上各种控制卡种类繁多,今天先介绍下EQ系列的控制卡吧。其实通信实时性要求采用同步卡效果最佳,但是苦于现场不想增加专用的控制电脑(大部分同步卡原理即抓屏模式,实时展现电脑桌面的内容,电脑不能同时进行其他操作),所以决定采用异步卡异步通信,直接在后台通过程序建立和LED屏幕的连接,实时发送数据给LED屏幕。此篇就讲下根据官方二次开发包开发的问题。
此处我们采用的是网络通讯的方式,即EQ控制卡上需固定IP,用以识别并和控制程序建立连接。
EQ2008_Dll.dll是官方提供的开发接口,其中的接口方法包含如下:

EQ2008_Dll_Set.ini是LED屏幕的通信的配置文件,在屏幕初始化之前就要存在,可手动配置好放至程序运行的根目录,为了可复用性,在此将其在程序配置【通信地址(ip),端口号port),屏幕大小screenHeight,screenWidth),单双色colorStyle),控制卡型号cardType)】,在程序运行前(即Program.cs文件中动态生成EQ2008_Dll_Set.ini文件)
var screens = BLL.Common.DataSetCache.Screens; foreach var screen in screens) { if screen.screenType == Setting.屏幕类型.主控屏) ServiceCloud.Devices.Led.EQ2008.LedController.RegisterCardType.EQ2023, ScreenColorStyle.Multicolor, 224, 1024, screen.ip, 5005); if screen.screenType == Setting.屏幕类型.分装区屏) ServiceCloud.Devices.Led.EQ2008.LedController.RegisterCardType.EQ2023, ScreenColorStyle.Multicolor, 192, 192, screen.ip, 5005); if screen.screenType == Setting.屏幕类型.配发区屏) ServiceCloud.Devices.Led.EQ2008.LedController.RegisterCardType.EQ2023, ScreenColorStyle.Multicolor, 64, 384, screen.ip, 5005); } ServiceCloud.Devices.Led.EQ2008.LedController.Initialize);

在生成控制卡的通信配置文件以后再程序里面(如下图)
通过点击开始连接按钮(按钮事件如下)
private void OpenConnect) { try { var index = 0; var screenNumbers = GetCheckValuesfalse); if screenNumbers.Count <= 0) { MessageBoard.Errorthis, "请先勾选您所要操作的LED屏"); return; } foreach var screenNumber in screenNumbers) { var screenModel = DataSetCache.Screens.FirstOrDefaulto => o.number == screenNumber); var ledBasics = DataSetCache.LedBasics.FirstOrDefaulto => o.ScreenModel.ip == screenModel.ip); if ledBasics.ScreenState == EnumScreenState.Open) continue; if !ledBasics.ScreenModel.ip.PingIp)) { var message = string.Format"{0}-启动失败!可能原因:未找到当前屏幕的通信地址,请检查当前屏幕网络通信。", ledBasics.ScreenModel.name); MSGLSBOXmessage); Logger.Errormessage); continue; } var controller = ServiceCloud.Devices.Led.EQ2008.LedController.GetFromIPledBasics.ScreenModel.ip); if controller == null) { var message = string.Format"{0}-启动失败!可能原因:屏幕初始化失败。", ledBasics.ScreenModel.name); MSGLSBOXmessage); Logger.Errormessage); continue; } else if !controller.Open)) { var message = string.Format"{0}-启动失败!可能原因:屏幕打开失败。", ledBasics.ScreenModel.name); MSGLSBOXmessage); Logger.Errormessage); continue; } else { ledBasics.ScreenState = EnumScreenState.Open; if ledBasics.ScreenModel.screenType == Setting.屏幕类型.主控屏) { ledBasics.LedThread = new Threadnew ParameterizedThreadStartLedMainDrive)); ledBasics.LedThread.StartledBasics); } else if ledBasics.ScreenModel.screenType == Setting.屏幕类型.分装区屏) { ledBasics.LedThread = new Threadnew ParameterizedThreadStartLedPackingDrive)); ledBasics.LedThread.StartledBasics); } else if ledBasics.ScreenModel.screenType == Setting.屏幕类型.配发区屏) { if index == 0) ledBasics.LedThread = new Threadnew ParameterizedThreadStartLedDistributionDriveN4_1)); if index == 1) ledBasics.LedThread = new Threadnew ParameterizedThreadStartLedDistributionDriveN4_2)); if index == 2) ledBasics.LedThread = new Threadnew ParameterizedThreadStartLedDistributionDriveN4_3)); index++; ledBasics.LedThread.StartledBasics); } else MessageBoard.Errorthis, string.Format"未识别{0}的屏幕类型", ledBasics.ScreenModel.name)); } } RefreshScreenList); } catch { throw; } }

因为当前项目需要控制多个LED屏幕,所以此处采取独立线程去分别控制显示,以下是一个线程内的控制通信的代码
public void LedPackingDriveobject source) { while true) { try { var ledBasics = source as LedBasics; var packingScreenTwoSwitchingTime = Sys_SystemInfoManager.packingScreenTwoSwitchingTime * 2; var packingScreenOneSwitchingTime = Sys_SystemInfoManager.packingScreenOneSwitchingTime * 2; this.LedControllerForPackingBasic = ServiceCloud.Devices.Led.EQ2008.LedController.GetFromIPledBasics.ScreenModel.ip); this.LedControllerForPacking = new LedController.LedControllerForPackingthis.LedControllerForPackingBasic); if indexForPacking <= packingScreenTwoSwitchingTime) SendToPackingLedledBasics, false); else if indexForPacking > packingScreenTwoSwitchingTime && indexForPacking < packingScreenTwoSwitchingTime + packingScreenOneSwitchingTime) SendToPackingLedledBasics, true); else if indexForPacking >= packingScreenTwoSwitchingTime + packingScreenOneSwitchingTime) { indexForPacking = 0; continue; } indexForPacking++; Thread.Sleep500); } catch System.Exception ex) { Logger.Errorex); } } } private void SendToPackingLedLedBasics ledBasics, bool isSecondPages) { try { var dataItem = new LedController.LedControllerForPacking.ScreenDataItemForPacking); List<Obj_TaskManager> tasksForLackMaterial; var tasksForAll = ledBasics.Tasks; tasksForLackMaterial = from task in tasksForAll where task.taskState == Setting.作业状态.待执行 || task.taskState == Setting.作业状态.分拣中) && task.completeKit == Setting.齐套状态.缺料 select task).OrderByo => o.sequence).ToList); if tasksForLackMaterial.Count > 0) { dataItem.WorkNumber1 = tasksForLackMaterial[0].workNumber; dataItem.Line1 = tasksForLackMaterial[0].line; dataItem.WorkNumber2 = tasksForLackMaterial.Count > 1 ? tasksForLackMaterial[1].workNumber : "No Task"; dataItem.Line2 = tasksForLackMaterial.Count > 1 ? tasksForLackMaterial[1].line : "No Task"; var currentTaskChildMaterialCount1 = tasksForLackMaterial[0].CurrentTaskChildMaterialCount.Selecto => string.Format"{0}{1}", RemoveMaterialMemoEnglisho.childMaterialMemo), o.childMaterialCount)).ToArray).Join","); if scroll_Packing1 >= currentTaskChildMaterialCount1.Length) { dataItem.ScrollContent1 = currentTaskChildMaterialCount1; scroll_Packing1 = 0; } else { dataItem.ScrollContent1 = currentTaskChildMaterialCount1.Substringscroll_Packing1, currentTaskChildMaterialCount1.Length - scroll_Packing1); scroll_Packing1++; } if tasksForLackMaterial.Count > 1) { var currentTaskChildMaterialCount2 = tasksForLackMaterial[1].CurrentTaskChildMaterialCount.Selecto => string.Format"{0}{1}", RemoveMaterialMemoEnglisho.childMaterialMemo), o.childMaterialCount)).ToArray).Join","); if scroll_Packing2 >= currentTaskChildMaterialCount2.Length) { dataItem.ScrollContent2 = currentTaskChildMaterialCount2; scroll_Packing2 = 0; } else { dataItem.ScrollContent2 = currentTaskChildMaterialCount2.Substringscroll_Packing2, currentTaskChildMaterialCount2.Length - scroll_Packing2); scroll_Packing2 = scroll_Packing2 + 2; } } if isSecondPages) this.LedControllerForPacking.SendToScreendataItem, EnumScreenPackingType.ScreenDataForScrollContent); else this.LedControllerForPacking.SendToScreendataItem, EnumScreenPackingType.ScreenImageForTask); } else this.LedControllerForPacking.SendToScreendataItem, EnumScreenPackingType.ScreenImageForNoTask); } catch { throw; } }

其中
this.LedControllerForPacking.SendToScreendataItem, EnumScreenPackingType.ScreenImageForNoTask);
就是往控制卡(屏幕)中发送数据。此处只是简单的介绍下开发包的使用,以及简单设计。
