如何使用计时器与后台工作程序同步？

Question

我在应用程序中使用后台工作程序从硬件获取数据并在UI中不断更新。我需要配置硬件以从中获取信息。这里我的要求是每2秒更改一次硬件配置，并需要在UI中更新相应的信息。如何通过适当的同步实现这一目标？

编辑：  我在这里发布我的逻辑：

         worker3.WorkerReportsProgress = true;        
        worker3.WorkerSupportsCancellation = true;
        worker3.DoWork += new DoWorkEventHandler(worker3_DoWork);
        worker3.ProgressChanged += new ProgressChangedEventHandler(worker3_ProcessChanged);
         DispatcherTimer timer = new DispatcherTimer();
    private void Button_Click_1(object sender, RoutedEventArgs e)
    {
      timer.Interval = TimeSpan.FromSeconds(5);
       timer.Tick += timer_tick;
        timer.Start();

        worker3.RunWorkerAsync();

  }
    private void worker3_DoWork(object sender, DoWorkEventArgs e)
    {
       // Here running infinite loop. In that loop
      // i am calling the function in dll which will get the data from harware. Passing info which  i got to process changed event
    } 
      private void worker3_ProcessChanged(object sender, ProgressChangedEventArgs e)
    {
      // Here updating the UI with the information which i got from hardware.
    }

    private void time_tick(object sender, EventArgs )
  {
    if(worker3.IsBusy==true) 
         worker3.CancelAsync();

    // Configuring hardware with new options.
    // Again start the Background worker
    if(worker3.IsBusy!=true)
       worker3.RunAsync(); 
  }
