Web Monitoring

Web Monitoring Systems or WMS, and have become a standard means of solving and eliminating even the most difficult paper machine runnability issues. It is estimated that there are now over 1000 WMS systems around the world with Europe and North America representing around 80% of the installed base.

WMS systems have over the last decade become more intuitive allowing operators to quickly and efficiently find the root cause, or origin, of their break causing defect or other quality issue. Papertech’s TotalVision software and WebVision® cameras can monitor a preset region of interest on the paper web and alarm for any change in the sheet. WMS cameras now function the same way as web inspection systems (WIS) located at the reel. With TotalVision synchronization, defects mapped at the reel by WebInspector® can now be traced back to their exact location on the machine.

TotalVision WMS Software Features

• Camera Synchronization – The system provides easy to use configuration tools that allow for multiple speed and break inputs that can be used to synchronize the videos to the “same piece of paper” at every camera location.
• RealTime™ Analysis – Allows any camera to be configured to alarm and/or trigger an event capture when a change occurs in user definable region(s) of interest (ROI) as compared to a reference image.
• EdgeTracking™ – Allows any camera to be configured to track the position of an edge of the paper and alarm and/or trigger an event capture should the position move outside of user configurable limits.
• HandsFree™ Break Analysis – The software can be configured to automatically load the last triggered event and start playback of a synchronized loop of video from critical cameras in the system.
• Extended Video History – The user has easy control over access to video history from all of the cameras connected directly to the system. They can review the historical video and easily save desired clips to Permanent Storage.
• Break Within A Break – Since the system never stops recording images, there is no blackout period when an event occurs. This means that if the sheet were to break at the Reel and then break at the Size Press, each of these events could be captured for review and analysis.

• Grey Scale Display Bar – When opening either a Captured Event, or Extended Video History, a Grey Scale Display Bar is available that provides the user with quick feedback regarding where to start looking for the root cause of an event.
• Video Data Export – The system supports the capability to export video data (using a USB drive) in three ways that can then be used for display at any PC that support the standard file formats of JPG and AVI.
• Quick Marker – This tool allows the user to quickly place a marker on the Grey Scale Display Bar of a captured video as a reference that something has occurred in that frame of video. This can be repeated as needed and then using the single click Marker Settings button the user can quickly view the; number of frames, time and distance between each of the marks.
• Graphic Reports – The system comes standard with graphical reports that can display items like; types of breaks, break triggers, break locations, etc. on a time scale that is selectable by the user.

The 12 monitoring positions are represented by the single cameras shown on the paper machine. Systems can range from 1-20 or more cameras depending on the size of the machine and the customer requirements. The light coloured cameras are the WebInspector® inspection cameras. With TotalVision synchronization any defects detected at the reel can be traced back to their exact location.
