队列管理系统（Laravel 6）的通知声音实时更新

Question

我目前正在使用一个队列管理系统，该系统为客户提供一个队列号，并等待在display monitor.上可见的轮到他

当管理员端调用队列时，我该怎么做。队列号将自动显示在显示监视器上，而无需重新加载网页并发出通知声（如果可能的话，语音到文本的通知将读取队列号）？

到目前为止，系统可以调用队列。但是我需要在显示监视器上重新加载网页才能查看更新。

请帮助我。谢谢！

这是我用于呼叫队列的控制器：

public function callqueue(Request $request)
{
    $request->validate([
        'called'=>['max:255'],
        'counter'=>['max:255']
    ]);

    $dept=Auth::user()->department;
    Queue::where([
        ['department',$dept],
        ['called', 'no']
        ])
        ->whereDate('created_at', Carbon::today())
        ->orderBy('id', 'asc')
        ->first()
        ->update(['called'=>$request->called,'counter'=>$request->counter]);

    return redirect('admin')->withStatus(__('Queue has been called.'));

}

这是将显示队列的部分（在display.blade.php中）：
