Ascent monitoring for mines and shafts - involves monitoring roller system with drive chain of tubes by internal optical monitoring of tubes

摘要

The method involves monitoring a roller system with no disturbing technical devices such as conveyor devices. The roller system consists of a spooling arrangement with motor drive (MA), a drive chain with parallel tubes (PRO), internal monitoring of the tubes, electrical supply and signal cables, guide rails and control contacts (STK1,STK2). The system for internal monitoring of the tubes contains a light source and optical arrangement and a light receiver system contg. an optical arrangement and light detector. USE/ADVANTAGE - For monitoring the ascent of personnel from mines or shafts. The method utilises an extension of a specialised surface/vol./shape detection system.
