void Serie::Cfg()
{
   serial =  new QSerialPort();
   _thrSerial = new QThread;
   this->moveToThread(_thrSerial);
   serial->moveToThread(_thrSerial);
   _thrSerial->start();

   connect(_thrSerial, SIGNAL(started()), this, SLOT(PortProcess()));
   connect(_thrSerial, SIGNAL(finished()), this, SLOT(deleteLater()));

   connect(_thrSerial, SIGNAL(finished()), _thrSerial, SLOT(terminate()));
   connect(_thrSerial, SIGNAL(finished()), _thrSerial, SLOT(quit()));
}
void Serie::PortProcess()
{ 
   connect(serial, SIGNAL(readyRead()), this, SLOT(Receive8bits()));//,Qt::QueuedConnection);
   connect(serial, SIGNAL(error(QSerialPort::SerialPortError)), this, SLOT(ErrorHandle(QSerialPort::SerialPortError)));
   connect(_thrSerial, SIGNAL(finished()), this, SLOT(deleteLater()));
}
void Serie::Receive8bits()
{
   QByteArray lTmpByteArray = this->serial->readAll();
   if(!lTmpByteArray.isEmpty())
   {
       for(int i= 0; i< lTmpByteArray.size(); i +=1)
       {
          lData = lTmpByteArray[i]& 0x000000FF;
          FrameStateAdd(lData);
       }

   }
}

Serie::~Serie()
{
  if(serial !=NULL)
  {
    if(serial->isOpen())
        serial->close();//it is the source of problem
    delete serial;// problem
    serial = NULL;
  }
}

当我决定关闭qserialport（serial）的端口时，我有这个错误：

`Invalid parameter passed to C runtime function.
 ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to objects owned by a different thread. 
 Current thread 122f1b28. Receiver '' (of type 'QSerialPort') was created in thread 146b8c40", file kernel\qcoreapplication.cpp, line 502.`

QWinEventNotifier：无法从另一个线程禁用事件通知程序（movetothread和qserialport）
