实时信号记录与流传输
通过信号记录或流式传输，可视化实时应用程序运行中的实时信号
要评估信号在实时应用程序中的行为，您可以向模型中添加仪表，调整参数并显示结果。
仪表包含以下信号：通过仿真数据检查器或 Simulink® Scope 模块标记用于可视化的信号、连接至 File Log 模块的信号，以及通过仪表对象连接至图形化仪表的信号。您可以在实时应用程序中通过使用 Simulink Real-Time™ Explorer 或 MATLAB® 语言来对信号进行监控。
使用仿真数据检查器调整标量、向量或矩阵参数，并以数字形式或带时间戳的轨迹形式查看信号值。要确定需要调整的参数或需要观察的信号，请浏览模型层次结构或创建参数和信号组。
设计并运行包含图形仪表的 App Designer 仪表板。当运行仪表板时，它会持续与实时应用程序交互，并更新相关的参数和信号。
