用来给rfid设备定义端口及读写地址

// 定义一个config文件，放在下面目录
 QSettings settings("C:/Users/Administrator/.y/config.ini", QSettings::IniFormat);

 settings.beginGroup("PLC1"); // 指定当前操作组，开始组
 QString rfidPort1 = settings.value("rfidPort").toString();
 QString plcAddress1 = settings.value("plcAddress").toString();
 int plcPort1 = settings.value("plcPort").toInt();
 quint16 workpoint1 = settings.value("workpoint").toString().toUInt(nullptr, 16);
 quint16 plcSavePoint1 = settings.value("plcSavePoint").toString().toUInt(nullptr, 16);
 settings.endGroup(); // 结束组

 // 初始化第一个PLC读取器,此时的p是另外定义的一个cpp
 p = new PlcReader(rfidPort1,plcAddress1,plcPort1,workpoint1);
 p->plcSavePoint = plcSavePoint1;
 p->connectToPLC();
 p->waitForSignal();
