SCADA之JS脚本

产生虚拟数据

//产生随机数函数 function randomNum(minNum,maxNum){ switch(arguments.length){ case 1: return parseInt(Math.random()*minNum+1,10); break; case 2: return parseInt(Math.random()*(maxNum-minNum+1)+minNum,10); break; default: return 0; break; } } var sNodeIdArr1 =new Array();//电流 var sNodeIdArr2 =new Array();//电压 var sNodeIdArr3 =new Array();//焊接速度 var sNodeIdArr4 =new Array();//焊弧状态 var sNodeIdArr5 =new Array();//设备状态 for (var i=0;i<63;i++){ sNodeIdArr1[i]="ns=128;s=EQ_00"+(i+1)+".Current.PV";//电流 sNodeIdArr2[i]="ns=128;s=EQ_00"+(i+1)+".Voltage.PV";//电压 sNodeIdArr3[i]="ns=128;s=EQ_00"+(i+1)+".WireSpeed.PV";//焊接速度 sNodeIdArr4[i]="ns=128;s=EQ_00"+(i+1)+".WeldDetect.PV";//焊弧状态 sNodeIdArr5[i]="ns=128;s=EQ_00"+(i+1)+".State.PV";//设备状态 } var retVal1 = GetMulItemValue(sNodeIdArr1,0);//电流 var retVal2 = GetMulItemValue(sNodeIdArr2,0);//电压 var retVal3 = GetMulItemValue(sNodeIdArr3,0);//焊接速度 var retVal4 = GetMulItemValue(sNodeIdArr4,0);//焊弧状态 var retVal5 = GetMulItemValue(sNodeIdArr5,0);//设备状态 WriteDataToFile ("D:\\sNodeIdArr1.txt",sNodeIdArr1+"\r\n"); WriteDataToFile ("D:\\retVal1.txt",retVal1+"\r\n"); for (var j=0;j<63;j++){ var k=j*1; var run_id=k*3+1; var run5=retVal5[run_id];//设备状态 var Current;//电流 var Voltage;//电压 var WireSpeed;//焊接速度 var WeldDetect;//焊弧状态 if(run5==1){ Current=randomNum(294,310); Voltage=randomNum(25,29); WireSpeed=randomNum(7,10); WeldDetect=1; } else { Current=0; Voltage=0; WireSpeed=0; WeldDetect=0; } var Current_node="ns=128;s=EQ_00"+(j+1)+".Current.PV"; var Voltage_node="ns=128;s=EQ_00"+(j+1)+".Voltage.PV"; var WireSpeed_node="ns=128;s=EQ_00"+(j+1)+".WireSpeed.PV"; var WeldDetect_node="ns=128;s=EQ_00"+(j+1)+".WeldDetect.PV"; WriteDataToFile ("D:\\Current.txt",Current_node+":"+Current+"\r\n"); SetOneItemValue(Current_node,Current); SetOneItemValue(Voltage_node,Voltage); SetOneItemValue(WireSpeed_node,WireSpeed); SetOneItemValue(WeldDetect_node,WeldDetect); } WriteDataToFile ("D:\\Current.txt","循环完成"+"\r\n");

JS延迟

var sleep = function(time) { var startTime = new Date().getTime() + parseInt(time, 10); while(new Date().getTime() < startTime) {} }; sleep(1000); // 延时函数，单位ms

延迟+权限控制

var acookie=document.cookie.split(";"); console.log(acookie); var user = getUser(acookie); console.log(user); function getUser(acookie){ for(var i = 0;i < acookie.length;i ++){ acookie[i]=acookie[i].trim(); if(acookie[i].indexOf("_usr=")>=0){ return acookie[i].split("_usr=")[1] } } }; let arr = ['Admin', 'O管理员1']; let index = arr.indexOf(decodeURI(user)); console.log(index) //结果是2 let dm = data.getDataModel(); dm.getDataByTag("Text_4").s("text",decodeURI(user)); dm.getDataByTag("Text_10").s("text",index); if (index != -1){ var write0=writePointValue("ns=113;s=EQ_001.DI_001.PV",1); console.info(write0); setTimeout(function(){ writePointValue("ns=113;s=EQ_001.DI_001.PV",0); },500);}
