1。添加采集数据初始化接口 2.格式要求
{ rows:[], columns:[] }
{ "rows": [ { watertemperature:"-", flow:'-', pressure_out:'-', pressure_in:'-', rotate:'-', vol:'-', current:'-', power:'-', head:'-' } ], "columns": [ { "label": "水温度(°C)", "prop": "watertemperature", "name": "watertemperature", "className": "watertemperature" }, { "label": "流量(m³/h)", "prop": "flow", "name": "flow", "className": "flow" }, { "label": "出口压力(MPa)", "prop": "pressure_out", "name": "pressure_out", "className": "pressure_out" }, { "label": "进口压力(MPa)", "prop": "pressure_in", "name": "pressure_in", "className": "pressure_in" }, { "label": "转速(r/min)", "prop": "rotate", "name": "rotate", "className": "rotate" }, { "label": "电压(V)", "prop": "vol", "name": "vol", "className": "vol" }, { "label": "电流(A)", "prop": "current", "name": "current", "className": "current" }, { "label": "功率(kW)", "prop": "power", "name": "power", "className": "power" }, { "label": "扬程(m)", "prop": "head", "name": "head", "className": "head" }, { "label": "机组效率(%)", "prop": "effect", "name": "effect", "className": "effect" } ] }
## 3.数据采集下发  过程：增加一个控制下发的采集接口，点击按钮触发接口，后端发送要采集的数据 ## 4.实时数据展示  - 实时数据替换 ```javascript //conversion_flow：该数值为物模型的变量名 document.getElementsByClassName('conversion_flow')[3].innerHTML
