生产制造追溯系统-在线打印
前言
很久没有写博客了(大概有4个月的样子了吧)，从2015年8月份开始一直忙于公司的系统，直到2016年6月底全部上线；包含4个厂区，每个厂区都是上千人的规模，而负责搞这个项目的算上我只有2个人，说多了都是泪：
美工？没有
测试人员？没有
DBA？没有
架构师？没有
运维？继续没有
估计大家都没遇见过这样的工作吧？哈哈.
历经艰难、跟各个部门(IE、PE、生产、PMC、QA等)唇枪舌战、好在在6月底总算是全部上线，总算是一点欣慰，毕竟决定了接手这个项目，那就要用心去做，只有用心了才能做好。
吐槽完毕，下面开始说正事儿
********我是华丽的分割线************************************************
公司的系统上线之后，我也稍微可以缓口气了，加班稍微少了一点，一般到了下午6点半就能下班，所以我还是决定将2015年初整理的这套项目拿出来继续优化，该项目已Web模式为主、客户端模式为辅，互相结合使用；目前主要包含以下几个主要功能模块：
本文主要说一下打印的问题，在生产制造业中条码打印是非常频繁的，也是必不可少的；我曾经亲身经历过这么一件事情：生产线在进行包装的时候，打印了两张卡通标签，但是操作员在将卡通标签贴在盒子上的时候贴反了，也就是说标签上面的序列号与盒子里面装的实物完全对不上，为此在海关被拦截了，当时厂里派了QA、生产、货仓与IT一同去海关处解决这个问题，我刚好在其中，整个过程是非常繁琐的，为此公司高层也要求必须杜绝这种品质事件，故我们也是采用了"在线打印"的方式进行包装，并且只有QA才有标签重打的权限。
这个故事反应了生产线的真实现象，所以我这边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) { }; } }); }
以上代码是Web应用程序中的脚本，主要是通过API获取需要打印的数据，这里返回的是text类型，其实也可以返回Json格式的数据；用户完成包装之后系统会按照包装规则产生一个唯一的卡通箱号，那么这个箱号就作为API的参数 carton_sn= box传进去，根据该箱号返回真实的包装数据；然后通过window.external调用客户端的打印函数。
通过如下代码获取本地默认打印机：
//获取默认打印机 System.Drawing.Printing.PrintDocument pringdocument = new System.Drawing.Printing.PrintDocument(); string pring_name = pringdocument.PrinterSettings.PrinterName;//打印机名
因为我这里的客户端程序就是对Web程式加壳了，通过这个客户端程序就可以方便的获取本地默认打印机，采用这种方式比在网页中安装 activex 控件要爽的多，谁用谁知道.
网页传过来的参数以键值对为标准：
string[] keys = key.Split(splitKey.ToCharArray(), StringSplitOptions.None); string[] values = value.Split(splitKey.ToCharArray(), StringSplitOptions.None);
我这里调用BarTender进行打印，代码如下：
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);
以下代码是Code 128格式的条码：

这样一来，操作员手上没有多的条码，必须包装完成之后系统才会一对一的打印一份条码出来，完成一个产品的包装就贴一个条码，很大程度上面避免了条码混乱的问题.
已完成的部分功能
#1工单维护：这个一般都是由PMC完成的，PMC根据排期计划合理创建工单，如果企业上了SAP系统，也可以直接链接到SAP系统进行下载工单资料，这样就更方便了.
#2工单优先级：PMC在创建工单的时候会指定该信息，生产过程中系统会体现该信息，起到提示用户的目的，管理者可根据实际情况随时变更该信息。
#3工艺路线维护：工艺路线由 IE 完成，生产部根据 IE 制定的工艺路线进行生产，系统会检测每一个工序的通过情况，比如上一个工序没有做则不可以直接跳到下一个工序。
#4目检过站：操作扫描条码过站，必须按照 IE 制定的工艺路线进行，如果扫描的条码不在当前工序，则系统会提示当前条码的正确位置。
#5目检过站：系统会将不良品强制打入维修中心，在完成修理之前无法进行其它的操作。
#6组装动态装配：系统支持动态配置装配规则，不同的工单采用不同的规则进行装配，每一个装配条码可独立配置条码规则，比如长度、前缀等信息，防止用户输入错误。
#7FQC送检：系统采用 AQL 标准动态抽检，打破传统的抽检模式，由系统自动计算需要抽检的产品，同时也由系统自动根据 AQL 标准进行结果判定，有效帮助品质人员进行品质监控与管理。
#8FQC抽检：生产方面将产品以批次单位送检至QC，系统提示QC需要抽检的产品序列号，QC针对需要抽检的产品检测并录入抽检结果，系统根据抽检情况按照 AQL 自动判定.
#9包装规则：针对每个工单配置相应的包装规则，比如卡通箱容量、箱号长度、箱号前缀等信息，并上传卡通标签模板。
