1. Mapping映射表规范

1.1. Mappingtemplate（映射表模板）

Mapping_template出脚本主要作用于设备信息的扩展字段，在设备信息信息中需要显示哪些设备字段在此配置即可。

Image - 扩展字段示例

上图显示扩展字段代码模板如下：

[{
    "title": "锅炉信息",
    "data": [
        ["燃料类型", "天然气"],
        ["锅炉重量", "2吨"],
        ["出厂日期", "2018-03-03"]
    ]
}, {
    "title": "能效指标信息",
    "data": [
        ["热效率", 0.8],
        ["燃料热值", 7000],
        ["*吨汽燃料指标*", 0.21]
    ]
}]

Title：为段落标题，名称可自定义，即代码中“锅炉信息”、“能效指标信息”可更改。
Data：为段落中字段内容，字段名和字段值可自定义。

1.2. Mappingscript（映射表脚本）

Mapping_script处脚本主要将适配器上报的key映射为系统可识别的变量，并将适配器和设备的关系进行关联对应。

代码模板如下：

[
    ["S02","Instant Flow","瞬时流量","$AprusID-1","L1_3_0","STA"]
]

依次顺序说明：

变量
英文标签
中文标签
适配器标识
设备上报KEY
数据类型

*中文说明*	变量	英文标签	中文标签	适配器标识	设备上报KEY	数据类型
示例参考	S02	Instant Flow	瞬时流量	$AprusID-1	L1_3_0	STA

注：上述映射表中还有一类书写规则，离线数据和统计计算数据，这一类数据不是通过适配器上报的数据，而是通过外部程序获取数据，目前规则还未完善，待后续补充。

1.2.1. 变量

变量是系统可识别的KEY又名，适配器识别KEY，系统识别变量。通过映射，变量、参数名称、KEY可进行相互转换。

1.2.2. 标签

标签分为英文标签和中文标签。表示的是KEY的含义。

1.2.3. 适配器标识

$AprusID-1这样的适配器标识是将适配器标识经过宏替换后转化而来，后续的生产环境中也大多使用这种方式，也可以直接使用适配器标识，例如：瞬时流量中就直接写入的适配器标识。

具体规则见如下举例：

Image - 适配器的组合

如果这个是一个特定的设备与适配器的组合，我们把设备1-4定义为“设备”，Mapping我们可以这样写：

[
    ["X1","Device1Temperature","设备1温度","A8901","L1_1_123","STA"],
    ["X2","Device1Pressure","设备1压力","A8901","L1_1_234","STA"],
    ["X3","Device1Current","设备1电流","A8902","L1_1_123","STA"],
    ["X4","Device1Voltage","设备1电压","A8902","L1_1_234","STA"],
    ["X5","Device2Current","设备2电流","A8902","L1_1_345","STA"],
    ["X6","Device2Voltage","设备2电压","A8902","L1_1_456","STA"],
    ["X7","Device2Gas","设备2气量","A8903","L1_1_123","STA"],
    ["X8","Device2Hydro","设备2电量","A8903","L1_1_234","STA"],
    ["X9","Device3Gas","设备3气量","A8903","L1_1_345","STA"],
    ["X10","Device3Hydro","设备3电量","A8903","L1_1_456","STA"],
    ["X11","Device3Temperature","设备3温度","A8904","L1_1_123","STA"],
    ["X12","Device3Pressure","设备3压力","A8904","L1_1_234","STA"],
    ["X13","Device3Gas","设备3气量","A8905","L1_1_123","STA"],
    ["X14","Device3Hydro","设备3电量","A8905","L1_1_234","STA"],
    ["X15","Device4Gas","设备4气量","A8905","L1_1_345","STA"],
    ["X16","Device4Hydro","设备4电量","A8905","L1_1_456","STA"],
    ["X17","Device4Temperature","设备4温度","A8906","L1_1_123","STA"],
    ["X18","Device4Pressure","设备4压力","A8906","L1_1_234","STA"]
]

下面就是宏替换

[
    ["X1","Device1Temperature","设备1温度","$AprusID-1","L1_1_123","STA"],
    ["X2","Device1Pressure","设备1压力","$AprusID-1","L1_1_234","STA"],
    ["X3","Device1Current","设备1电流","$AprusID-2","L1_1_123","STA"],
    ["X4","Device1Voltage","设备1电压","$AprusID-2","L1_1_234","STA"],
    ["X5","Device2Current","设备2电流","$AprusID-2","L1_1_345","STA"],
    ["X6","Device2Voltage","设备2电压","$AprusID-2","L1_1_456","STA"],
    ["X7","Device2Gas","设备2气量","$AprusID-3","L1_1_123","STA"],
    ["X8","Device2Hydro","设备2电量","$AprusID-3","L1_1_234","STA"],
    ["X9","Device3Gas","设备3气量","$AprusID-3","L1_1_345","STA"],
    ["X10","Device3Hydro","设备3电量","$prusID-3","L1_1_456","STA"],
    ["X11","Device3Temperature","设备3温度","$AprusID-4","L1_1_123","STA"],
    ["X12","Device3Pressure","设备3压力","$AprusID-4","L1_1_234","STA"],
    ["X13","Device3Gas","设备3气量","$AprusID-5","L1_1_123","STA"],
    ["X14","Device3Hydro","设备3电量","$AprusID-5","L1_1_234","STA"],
    ["X15","Device4Gas","设备4气量","$AprusID-5","L1_1_345","STA"],
    ["X16","Device4Hydro","设备4电量","$AprusID-5","L1_1_456","STA"],
    ["X17","Device4Temperature","设备4温度","$AprusID-6","L1_1_123","STA"],
    ["X18","Device4Pressure","设备4压力","$AprusID-6","L1_1_234","STA"]
]

只要符合这样对应关系的设备,只需要保证在设备的AprusList属性中的顺序是（AprusID-1,AprusID-2,….,AprusID-6)就行了。MosaicMaker程序就是根据这个,去进行Mosaic拼图,拼出来的结果,就是Mosaic={"X1":$X1,"X2":$X2,….,"Xn":$Xn},每个Xi就是对应的某个设备的参数。

1.2.4. 上报数据KEY

定义的KEY直接在数据表中可获取。为区分数据类型，所以KEY的开头字母根据不同,数据类型有所不同

事件：E开头，例如E1_2_3
报警：A开头，例如A1_2_3
故障：F开头，例如F1_2_3
运行参数：L开头，例如L1_2_3
运行状态：直接以Z表示

1.2.5. 数据类型

数据类型分别为：STA（状态）、SET（设置）、CMD（控制）、FLT（故障）、ALT（报警）、EVNT（事件）

注：脚本中所需书写的数据类型在数据表中可直接查询。
