从中找出数据的头，然后读取数据

if(readedDataBuffer.Count>=20){intremoveCount=0;for(inti=0;i<readedDataBuffer.Count-18;++i){//147B节点if(readedDataBuffer[i]==0xFD&readedDataBuffer[i+4]==0x28&readedDataBuffer[i+5]==0x7B){byte[]data=newbyte[20];/*节点*/intdata31,data32;doublev3,T3;data31=readedDataBuffer[i+12];//高八位data32=readedDataBuffer[i+13];//低八位v3=(data31*256+data32);//电压值T3=-39.66+0.01*v3+0.026;tcure=T3;wendu=T3.ToString();}removeCount++;}}
