整体交互图
[小 迪 导读]：应用条码系统整体优势
1.条形码是迄今为止最经济、实用的一种自动识别技术。条形码技术具有以下几个方面的优点；
2.输入速度快：与键盘输入相比，条形码输入的速度是键盘输入的5倍，并且能实现“即时数据输入”；
3.可靠性高：键盘输入数据出错率为三百分之一，利用光学字符识别技术出错率为万分之一，而采用条形码技术误码率低于百万分之一；
4.灵活实用：条形码标识既可以作为一种识别手段单独使用，也可以和共它识别设备组成一个系统实现自动化识别，还可以和其他控制设备联接起来实现自动化管理。
生成条码打印
1.生产部门在每一次报工时会生成生产单据,利用数据内部关系生成一个唯一标识编码，
get_id(DevAddr, Type) ->
Time = dgiot_utils:to_binary(dgiot_datetime:timestamp()),
Bin = dgiot_utils:to_binary(Type),
<<ObjID:10/binary, _/binary>> = dgiot_utils:to_md5(<<Bin/binary, DevAddr/binary, Time/binary>>),
Res = string:to_upper(dgiot_utils:to_list(ObjID)),
dgiot_utils:to_binary(Res).
2.通过dgiot_amis下发给dgiot_dtu
{
"type": "page",
"body": [
{
"tabs": [
{
"body": [
{
"id": "u:04459a03cf7c",
"api": {
"url": "iotapi/amis/Device/parse_objectid",
"method": "get",
"adaptor": "return {\r\n \"status\":0,\r\n \"msg\":\"\",\r\n \"data\":response\r\n }",
"headers": {
"store": "localStorage",
"dgiotReplace": "parse_objectid"
}
},
"body": [
{
"id": "u:94629dd6e880",
"api": {
"url": "iotapi/classes/Device/parse_objectid",
"method": "put",
"headers": {
"store": "localStorage",
"dgiotReplace": "parse_objectid"
},
"requestAdaptor": "return{\r\n ...api,\r\n data:{\r\n profile:{\r\n ...api.data\r\n }\r\n }\r\n}"
},
"body": [
{
"mode": "inline",
"name": "data",
"size": "",
"type": "input-text",
"label": "打印内容",
"disabled": false,
"readOnly": false,
"horizontal": {
"left": 4,
"right": 8,
"leftFixed": ""
},
"validateApi": "",
"autoComplete": false
},
{
"mode": "inline",
"name": "cmd",
"size": "",
"type": "input-text",
"label": "操作",
"disabled": false,
"readOnly": false,
"horizontal": {
"left": 4,
"right": 8,
"leftFixed": ""
},
"validateApi": "",
"autoComplete": false
}
],
"type": "form",
"title": "",
"submitText": "打印"
}
],
"type": "form",
"title": "表单",
"submitText": ""
}
],
"icon": "fa fa-slideshare",
"title": "设备信息"
}
],
"type": "tabs"
}
]
}
3.dgiot_dtu通过唯一标识编码生成条形码
public static Image Get_image()
{
CodeLib.Barcode b = new CodeLib.Barcode();
CodeLib.TYPE type = CodeLib.TYPE.CODE128B;
b.IncludeLabel = false;
string familyName = "宋体";
Font Label = new Font(familyName, 10.0F);
b.LabelFont = Label;
CodeLib.AlignmentPositions Align = CodeLib.AlignmentPositions.CENTER;
b.Alignment = Align;
b.LabelPosition = CodeLib.LabelPositions.BOTTOMCENTER;
return b.Encode(type, textData, 157, 80);
}
4.再给默认打印机下发打印指令
public static void PrintPage(string data, string url, Dictionary<string, object> json)
{
SetTextData(data);
SetTextUrl(url);
Setjson(json);
PrintDialog PD = new PrintDialog();
PageSettings pageSettings = new PageSettings();
//pageSettings.PaperSize = new PaperSize("Size", 30, 40);
string Name = fPrintDocument.PrinterSettings.PrinterName;
LogHelper.Log("PrinterName: " + Name.ToString());
System.Drawing.Printing.PrinterSettings Ps = new System.Drawing.Printing.PrinterSettings();
//SetDefaultPrinter("Deli DL-888B(NEW)");
fPrintDocument.DefaultPageSettings.PaperSize = new PaperSize("Size", 393, 275); //单位1/100英寸
SetDefaultPrinter(Name);
PD.PrinterSettings = Ps;
fPrintDocument.PrintPage += document_PrintPage;
PD.Document = fPrintDocument;
fPrintDocument.Print();
}
追溯条码
1.品检部门在检查时通过amis配置的表单按钮，向dgiot_app发起扫码请求
{
"type": "button",
"api": {
"url": "http://192.168.2.5:12345/scancode",
"method": "get",
"headers": {
"Origin": "asdaszxc"
},
"requestAdaptor": "console.log('请求参数',api)\r\ndelete api.headers.author\r\ndelete api.headers.email\r\nreturn {\r\n ...api\r\n}"
},
"label": "扫码",
"actionType": "ajax"
}
2.dgiot_app收到请求，验证接口参数，下发扫码指令
public Response scancode(IHTTPSession session) {
JSONObject map = new JSONObject();
JSONObject data = new JSONObject();
String Json = "{'code':200,'datetimes':'','deviceid':'1db7727cc6','instruct':'scancode','msg':'success','objectId':'1db7727cc6','username':'username'}";
ReceiveMsgBean msgBean = JSONObject.parseObject(Json, ReceiveMsgBean.class);
Log.d("hallow", "Json=" + Json);
Log.d("hallow", "msgBean=" + msgBean);
EventBus.getDefault().post(msgBean);
String text=webActivity.geturl();
data.put("scancode", text);
map.put("status", 0);
map.put("msg", "");
map.put("data", data);
Response resp = newFixedLengthResponse(map.toJSONString());
resp.addHeader("Access-Control-Allow-Methods", "GET, PUT, POST, DELETE, HEAD, OPTIONS, TRACE, CONNECT, PATCH, PROPFIND, PROPPATCH, MKCOL, MOVE, COPY, LOCK, UNLOCK");
Log.d("hallow", "map=" + map.toJSONString());
String origin=session.getHeaders().get("origin");
resp.addHeader("Access-Control-Allow-Origin", origin);
resp.addHeader("Access-Control-Allow-Headers", "*");
resp.addHeader("Access-Control-Max-Age", "3600");
resp.addHeader("Access-Control-Allow-Credentials", "true");
return resp;
}
3.通过人工扫码，dgiot_app再获取条码编码
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch ( resultCode ){
case 33:
jsonObject = new JSONObject();
jsonObject.put("deviceid",receiveMsgBean.getDeviceid());
jsonObject.put("instruct",QR_KEY);
jsonObject.put("url",data.getStringExtra("mCode"));
seturl(data.getStringExtra("mCode"));
DgiotService.publish( JSONObject.toJSONString( jsonObject ) );
// rdb.setInstruct(data.getStringExtra("mCode"));
break;
default:break;
}
}
4.dgiot_app通过Response响应把条码编号返回给dgiot_amis搜索框
{
"type": "input-text",
"id": "u:6b51eebdf49c",
"name": "scancode",
"label": "扫码结果"
}
5.搜索框调用get_data接口通过条码编号可迅速的把生产单据信息作为表格返回
get_all_sheet(ProductId, Start, End, Channel, DeviceId, Where, Limit, Skip, New) ->
UnflattenWhere = unflatten_where(Where),
case dgiot_hook:run_hook({factory, get_sheet_list}, [ProductId]) of
{ok, [{ok, SheetList}]} ->
SheetsData = lists:foldl(
fun(X, Acc) ->
SheetWhere = get_sheet_where(X, UnflattenWhere),
case dgiot_factory_getdata:get_work_sheet(ProductId, X, Start, End, Channel, DeviceId, SheetWhere, undefined, undefined, New) of
{ok, {_, Res}} ->
Acc ++ [Res];
_ ->
Acc
end
end, [], SheetList),
IdData = get_sheet_id(SheetsData, SheetList),
MergedData = merge_sheets(IdData, SheetList),
%% Data = maps:values(MergedData),
{Total, Res} = filter_data(Limit, Skip, MergedData),
{ok, {Total, Res}};
_ ->
error
end.
