前言
很久沒有寫博客了(大概有4個月的樣子了吧)，從2015年8月份開始一直忙于公司的系統，直到2016年6月底全部上線；包含4個廠區，每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個人，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
估計大家都沒遇見過這樣的工作吧？哈哈.
歷經艱難、跟各個部門(IE、PE、生產、PMC、QA等)唇槍舌戰、好在在6月底總算是全部上線，總算是一點欣慰，畢竟決定了接手這個項目，那就要用心去做，只有用心了才能做好。
吐槽完畢，下面開始說正事兒
********我是華麗的分割線************************************************
公司的系統上線之后，我也稍微可以緩口氣了，加班稍微少了一點，一般到了下午6點半就能下班，所以我還是決定將2015年初整理的這套項目拿出來繼續優化，該項目已Web模式為主、客戶端模式為輔，互相結合使用；目前主要包含以下幾個主要功能模塊：
本文主要說一下打印的問題，在生產制造業中條碼打印是非常頻繁的，也是必不可少的；我曾經親身經歷過這么一件事情：生產線在進行包裝的時候，打印了兩張卡通標簽，但是操作員在將卡通標簽貼在盒子上的時候貼反了，也就是說標簽上面的序列號與盒子里面裝的實物完全對不上，為此在海關被攔截了，當時廠里派了QA、生產、貨倉與IT一同去海關處解決這個問題，我剛好在其中，整個過程是非常繁瑣的，為此公司高層也要求必須杜絕這種品質事件，故我們也是采用了"在線打印"的方式進行包裝，并且只有QA才有標簽重打的權限。
這個故事反應了生產線的真實現象，所以我這邊采用如下方式完成打印：
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，主要是通過API獲取需要打印的數據，這里返回的是text類型，其實也可以返回Json格式的數據；用戶完成包裝之后系統會按照包裝規則產生一個唯一的卡通箱號，那么這個箱號就作為API的參數 carton_sn= box傳進去，根據該箱號返回真實的包裝數據；然后通過window.external調用客戶端的打印函數。
通過如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
因為我這里的客戶端程序就是對Web程式加殼了，通過這個客戶端程序就可以方便的獲取本地默認打印機，采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為標準：
string[] keys = key.Split(splitKey.ToCharArray(), StringSplitOptions.None); string[] values = value.Split(splitKey.ToCharArray(), StringSplitOptions.None);
我這里調用BarTender進行打印，代碼如下：
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);以下代碼是Code 128格式的條碼：
public class Code128
{
private DataTable m_Code128 = new DataTable();
private uint m_Height = 40;
/// <summary>
/// 高度
/// </summary>
public uint Height { get { return m_Height; } set { m_Height = value; } }
private Font m_ValueFont = null;
/// <summary>

已完成的部分功能
#1工單維護：這個一般都是由PMC完成的，PMC根據排期計劃合理創建工單，如果企業上了SAP系統，也可以直接鏈接到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在創建工單的時候會指定該信息，生產過程中系統會體現該信息，起到提示用戶的目的，管理者可根據實際情況隨時變更該信息。
#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，系統會檢測每一個工序的通過情況，比如上一個工序沒有做則不可以直接跳到下一個工序。
#4目檢過站：操作掃描條碼過站，必須按照 IE 制定的工藝路線進行，如果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，在完成修理之前無法進行其它的操作。
#6組裝動態裝配：系統支持動態配置裝配規則，不同的工單采用不同的規則進行裝配，每一個裝配條碼可獨立配置條碼規則，比如長度、前綴等信息，防止用戶輸入錯誤。
#7FQC送檢：系統采用 AQL 標準動態抽檢，打破傳統的抽檢模式，由系統自動計算需要抽檢的產品，同時也由系統自動根據 AQL 標準進行結果判定，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需要抽檢的產品序列號，QC針對需要抽檢的產品檢測并錄入抽檢結果，系統根據抽檢情況按照 AQL 自動判定.
#9包裝規則：針對每個工單配置相應的包裝規則，比如卡通箱容量、箱號長度、箱號前綴等信息，并上傳卡通標簽模板。
#10包裝：包裝規則配置完成之后，即可掃描條碼進行包裝了。
結束包裝的時候，系統自動將標簽打印出來.
#11不良品維修：生產過程中的不良都會被系統強制打入維修中心，必須經過修理之后才能進行其它工序。
#12不良預警：系統會自動監控指定生產線的不良情況，當不良情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，由管理者分析不良原因并改善之后進行解除預警。
#13成品發貨：成品發貨過程中支持上傳實物圖片。
#14品質異常報告：用戶發起品質異常，由工程部分析原因并給出改善，由QA確認是否可行。
#15部分報表：
#16電子看板：

因為工作日需要上班，白天必須做公司的事情，所以只有每天晚上熬夜和周末來做這個項目，說真的還是有點累，如果您覺得文章過得去，還請多多支持，謝謝各位園友！！
