生產製造追溯系統-在線打印

前言

好久沒有寫博客了(大概有4個月的樣子了吧)，從2015年8月份開始一直忙於公司的系統，直到2016年6月底所有上線；包含4個廠區，每一個廠區都是上千人的規模，而負責搞這個項目的算上我只有2我的，說多了都是淚：

美工？沒有

測試人員？沒有

DBA？沒有

架構師？沒有

運維？繼續沒有

估計你們都沒碰見過這樣的工做吧？哈哈.

歷經艱難、跟各個部門(IE、PE、生產、PMC、QA等)脣槍舌戰、好在在6月底總算是所有上線，總算是一點欣慰，畢竟決定了接手這個項目，那就要用心去作，只有用心了才能作好。

吐槽完畢，下面開始說正事兒

********我是華麗的分割線************************************************

公司的系統上線以後，我也稍微能夠緩口氣了，加班稍微少了一點，通常到了下午6點半就能下班，因此我仍是決定將2015年初整理的這套項目拿出來繼續優化，該項目已Web模式爲主、客戶端模式爲輔，互相結合使用；目前主要包含如下幾個主要功能模塊：

本文主要說一下打印的問題，在生產製造業中條碼打印是很是頻繁的，也是必不可少的；我曾經親身經歷過這麼一件事情：生產線在進行包裝的時候，打印了兩張卡通標籤，可是操做員在將卡通標籤貼在盒子上的時候貼反了，也就是說標籤上面的序列號與盒子裏面裝的實物徹底對不上，爲此在海關被攔截了，當時廠裏派了QA、生產、貨倉與IT一同去海關處解決這個問題，我恰好在其中，整個過程是很是繁瑣的，爲此公司高層也要求必須杜絕這種品質事件，故咱們也是採用了"在線打印"的方式進行包裝，而且只有QA纔有標籤重打的權限。

這個故事反應了生產線的真實現象，因此我這邊採用以下方式完成打印：

     function PrintLabel(box) {
            var api = '<%=MTS.Utility.MtsTool.GetApi() %>';
            
            var lurl = api + "?type=3&action=get_carton_sn&carton_sn=" + box;
            $.ajax({ url: lurl,
                cache: false,
                dataType: "text",
                success: function (data) {
                    if (data == null || data == undefined) {
                        alert("");
                        return;
                    }
                    var arr = data.split("|");
                    if (arr[0] == "0") {
                        alert(arr[2]);
                        return;
                    }
                    var t = eval("(" + arr[2] + ")"); //                                                              
                    try {
                        var labelId = $("#hid_LabelId").val();
                        window.external.PrintLabel("", t.key, t.value, ",", labelId);

                    } catch (e) {

                    };
                }
            });
        }

以上代碼是Web應用程序中的腳本，主要是經過API獲取須要打印的數據，這裏返回的是text類型，其實也能夠返回Json格式的數據；用戶完成包裝以後系統會按照包裝規則產生一個惟一的卡通箱號，那麼這個箱號就做爲API的參數 carton_sn= box傳進去，根據該箱號返回真實的包裝數據；而後經過window.external調用客戶端的打印函數。

經過以下代碼獲取本地默認打印機：

 

  //獲取默認打印機
            System.Drawing.Printing.PrintDocument pringdocument = new System.Drawing.Printing.PrintDocument();
            string pring_name = pringdocument.PrinterSettings.PrinterName;//打印機名

 

由於我這裏的客戶端程序就是對Web程式加殼了，經過這個客戶端程序就能夠方便的獲取本地默認打印機，採用這種方式比在網頁中安裝 activex 控件要爽的多，誰用誰知道.

網頁傳過來的參數以鍵值對爲標準：

  string[] keys = key.Split(splitKey.ToCharArray(), StringSplitOptions.None);
  string[] values = value.Split(splitKey.ToCharArray(), StringSplitOptions.None);

我這裏調用BarTender進行打印，代碼以下：

 format = (BarTender.FormatClass)engine.Formats.Open(filename);
 format.SetNamedSubStringValue(key, value);
 format.PrintSetup.Printer = printerName;
 BarTender.Messages msg = null;
 format.Print("0", false, 1, out msg);

 如下代碼是Code 128格式的條碼：

  1  public class Code128
  2     {
  3         private DataTable m_Code128 = new DataTable();
  4         private uint m_Height = 40;
  5         /// <summary>
  6         /// 高度
  7         /// </summary>
  8         public uint Height { get { return m_Height; } set { m_Height = value; } }
  9         private Font m_ValueFont = null;
 10         /// <summary>

 14         private byte m_Magnify = 0;

這樣一來，操做員手上沒有多的條碼，必須包裝完成以後系統纔會一對一的打印一份條碼出來，完成一個產品的包裝就貼一個條碼，很大程度上面避免了條碼混亂的問題.

已完成的部分功能

 

#1工單維護：這個通常都是由PMC完成的，PMC根據排期計劃合理建立工單，若是企業上了SAP系統，也能夠直接連接到SAP系統進行下載工單資料，這樣就更方便了.

#2工單優先級：PMC在建立工單的時候會指定該信息，生產過程當中系統會體現該信息，起到提示用戶的目的，管理者可根據實際狀況隨時變動該信息。

#3工藝路線維護：工藝路線由 IE 完成，生產部根據 IE 制定的工藝路線進行生產，系統會檢測每個工序的經過狀況，好比上一個工序沒有作則不能夠直接跳到下一個工序。

#4目檢過站：操做掃描條碼過站，必須按照 IE 制定的工藝路線進行，若是掃描的條碼不在當前工序，則系統會提示當前條碼的正確位置。

#5目檢過站：系統會將不良品強制打入維修中心，在完成修理以前沒法進行其它的操做。

 #6組裝動態裝配：系統支持動態配置裝配規則，不一樣的工單採用不一樣的規則進行裝配，每個裝配條碼可獨立配置條碼規則，好比長度、前綴等信息，防止用戶輸入錯誤。

 #7FQC送檢：系統採用 AQL 標準動態抽檢，打破傳統的抽檢模式，由系統自動計算須要抽檢的產品，同時也由系統自動根據 AQL 標準進行結果斷定，有效幫助品質人員進行品質監控與管理。

 #8FQC抽檢：生產方面將產品以批次單位送檢至QC，系統提示QC須要抽檢的產品序列號，QC針對須要抽檢的產品檢測並錄入抽檢結果，系統根據抽檢狀況按照 AQL 自動斷定.

 

 

  #9包裝規則：針對每一個工單配置相應的包裝規則，好比卡通箱容量、箱號長度、箱號前綴等信息，並上傳卡通標籤模板。

 

#10包裝：包裝規則配置完成以後，便可掃描條碼進行包裝了。

 

結束包裝的時候，系統自動將標籤打印出來.

 

 

#11不良品維修：生產過程當中的不良都會被系統強制打入維修中心，必須通過修理以後才能進行其它工序。

#12不良預警：系統會自動監控指定生產線的不良狀況，當不良狀況達到了紅色預警值，則觸發警報，系統自動鎖定當前生產線，由管理者分析不良緣由並改善以後進行解除預警。

 

#13成品發貨：成品發貨過程當中支持上傳實物圖片。

 #14品質異常報告：用戶發起品質異常，由工程部分析緣由並給出改善，由QA確認是否可行。

 #15部分報表：

 #16電子看板：

由於工做日須要上班，白天必須作公司的事情，因此只有天天晚上熬夜和週末來作這個項目，說真的仍是有點累，若是您以爲文章過得去，還請多多支持，謝謝各位園友！！
