NOV Strix视觉技术进行粘贴高度检测(SHD)

使用摄像机来优化钻孔过程的视觉技术(Vision technology)。

Strix系列视觉技术可以帮助您改进目前已经达到了实际限制的解决方案的过程自动化，过程优化和增强安全性。该技术使用高清晰度摄像机和快速图像处理来自动操作钻孔过程，否则将需要操作员的手动干预。虽然该技术有许多可能的应用，但我们目前提供的Strix视觉技术主要用于自动化粘贴高度检测(SHD)。

铁钻的水平和垂直移动通常是独立的轨迹，在工具辅助下安装的传感器可以检测管道和工具接头颈。标准进程需要操作员目测确认正确的铁颚夹爪位置，并在需要时手动调整刀具高度。通过使用摄像机和视觉算法，可以获得准确的管道粘贴高度。该控制系统使用粘贴高度值，将铁钻从停放位置移动到指示的正确位置，同时执行水平和垂直运动(参见图2)。优化轨道减少了铁钻进入和站立所需的总体时间。

Strix™ Stickup Height Detection

Vision technology that uses cameras to optimize the drilling process.

The Strix family of vision technology answers your call for improved process automation, process optimization and enhanced safety where current solutions have reached their practical limits. The technology uses a high definition camera and fast image processing to automate drilling processes that otherwise would require an operator’s manual intervention. While there are many possible applications for this technology, we are currently offering Strix vision technology for automatic Stickup Height Detection (SHD).

Horizontal and vertical movements of the iron roughneck are typically independent trajectories, aided by tool-mounted sensors detecting the pipe and tool joint neck. The standard process requires an operator to visually verify correct iron roughneck jaw position and manually adjust the tool height if needed. By using a camera and vision algorithms, accurate pipe stickup height is obtained. The control system uses the stickup height value and commands the iron roughneck from parked position to the correct make-up position performing simultaneous horizontal and vertical movements (see Figure 2). The optimized trajectory reduces the overall time needed for trip-in and stand building.
