CoaXPress-over-Fiber 是什么?
CoaXPress-over-Fiber 是什么?

CoaXPress-over-Fiber 是对现有 CoaXPress 规范进行的较少但却很重要的扩展,旨在支持光纤传输。
CoaXPress (CXP)是业界高带宽计算机视觉应用标准。最新版CoaXPress 2.1规范中规定了CXP-12速度,即通过同轴铜缆进行12.5 Gbps(千兆位每秒)连接。由于链路聚合在CoaXPress中很常见,因此四路CXP-12连接可以轻松实现50 Gbps (12.5 x 4)的带宽。CoaXPress-over-Fiber是CoaXPress规范的附加部分。它提供了一种通过标准以太网连接(包括光纤)运行未经修改的CoaXPress协议的方法。因此,CoaXPress-over-Fiber使用为以太网设计的标准电子设备、连接器和电缆,但所采用的协议既不是以太网,也不是GigE Vision,而是CoaXPress。

使用光纤有何优缺点?


优点

  • 首先,由于光纤连接长度基本不受限制,因此电缆长度不再是问题。
  • 光纤提供更高的带宽,如今每条光纤的标准连接速度为 10 Gbps 和 25 Gbps,并且在数据中心得到广泛使用。
  • 光纤不受电噪声的影响,对于生产车间和某些医疗应用而言,这是一大重要优势。
  • 光纤比同等的铜缆更轻便、小巧,很适合于必须具备这一特点的应用,例如飞机或车辆。

缺点
  • 不能“通过光纤传送电能”。由于光纤中的信号通过光传输,因此无法通过光纤传送电能,诸如相机等设备必须单独供电。


CoaXPress-over-Fiber 的抖动和延迟是多少?它们与“传统”CoaXPress 相比如何?

CoaXPress-over-Fiber 基于 CoaXPress 协议,在抖动和延迟方面,其性能与 CoaXPress 一样高。另外,CoaXPress-over-Fiber 比 CoaXPress 支持的传输速度更高,因此这些版本中的抖动和延迟将得到进一步改善。


Memento 事件日志工具

  • Memento是供Coaxlink和Grablink卡使用的高级开发和调试工具。
  • Memento 记录与相机、图像采集卡及其驱动程序以及应用程序相关的所有事件的准确日志。
  • 对于包含时间戳的时间,它为开发人员提供精确的时间表,也提供上下文信息和逻辑分析器视图。

  • 触发器用于在零件就位时启动采集。硬件触发器来自主板 I/O 线。软件触发器来自于应用程序。
  • 启动以后,采集将:
    • 无限进行下去 (用于滚网式监测应用)
    • 继续进行可编程的行数(以采集已知长度的目标图像)
    • 继续进行直至收到结束触发信号(以采集可变长度的目标图像)
  • 可控的延时触发器,用来以可编程的行数推迟开始采集。

CoaXPress-over-Fiber 的电缆选择有哪些?
CoaXPress-over-Fiber 的电缆选择有哪些?

CoaXPress-over-Fiber 最重要的优势之一,就是众多公司已提供多种连接选择。10 Gbps CoaXPress-over-Fiber 和 Coaxlink QSFP+ 的的初始连接选择有 SFP+ 和 QSFP+(Quad 或四倍 SFP+)模块。 相较于固定接口,使用模块的优势在于可以根据应用要求为端口配备任何合适类型的收发器。由于可以使用的发送器和接收器类型多样,因此用户可以选择合适的收发器,通过多模或单模光纤提供所需的光学范围。

  • 直接传送到用户分配的内存
  • 硬件分散 - 聚集支持


线扫描触发能力 2/2

  • Coaxlink 图像采集卡根据从运动编码器接收到的信号来控制相机扫描率。如果零件移动速度变快,相机的采集线率将增大。如果零件移动速度变慢,相机的采集线率将减小。
  • Coaxlink 板解读来自正交运动编码器的 A/B 信号,了解零件向哪个方向(向前或向后)移动。
  • 也可以在对象只向前移动或只向后移动时命令 Coaxlink 卡采集激光线。
  • 监测到向后运动时,名为“向后动作取消”的功能即停止采集。当在采集中断位置再次向前运动时,自动恢复行采集。
  • 速率转换器能够让相机以任何低于或高于运动编码器分辨率的可编程分辨率来采集行。这就为设计师在应用程序开发过程中提供了惊人的自由度和灵活度。
  • 速率分割器允许相机采集的图像分辨率高于或低于运动编码器的分辨率,它实现于利用一个可编程的整数倍来对编码器输入信号进行分割。
