  • 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:

      1  public class Code128
      2     {
      3         private DataTable m_Code128 = new DataTable();
      4         private uint m_Height = 40;

    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。

    #10包装:包装规则配置完成之后,即可扫描条码进行包装了。

    结束包装的时候,系统自动将标签打印出来.

    #11不良品维修:生产过程中的不良都会被系统强制打入维修中心,必须经过修理之后才能进行其它工序。

    #12不良预警:系统会自动监控指定生产线的不良情况,当不良情况达到了红色预警值,则触发警报,系统自动锁定当前生产线,由管理者分析不良原因并改善之后进行解除预警。

    #13成品发货:成品发货过程中支持上传实物图片。

     #14品质异常报告:用户发起品质异常,由工程部分析原因并给出改善,由QA确认是否可行。

     #15部分报表:

     #16电子看板:

    结尾

     

     

    因为工作日需要上班,白天必须做公司的事情,所以只有每天晚上熬夜和周末来做这个项目,说真的还是有点累,如果您觉得文章过得去,还请多多支持,谢谢各位园友!!
