Proximity detection

Proximity systems help to alert personnel to hazards while working around large machines in low visibility and obscured operator line-of-sight locations

Komatsu has developed a personal proximity detection system for use on the longwall face to help control automated shield movements when personnel are nearby. This system utilizes fully integrated low-power wireless transceivers in each RS20s Faceboss mimic to determine the location of each person wearing a battery-powered tag or personal wearable device (PWD). The PWD currently uses relative RF signal strength and an accelerometer to locate the operator's position.

• Existing RS20s systems can be upgraded to operate personal proximity detection by simply upgrading the mimic to the latest Faceboss version.
• Komatsu’s proprietary web-based user interface Longwall Information System (LIS) is utilized to set up the system and display live tracking information.
• Safety standards:
  • IEC61508 SIL 1 - Certified safety system
  • Sira 13 ATEX - Europe
  • IECEx SIR - International
  • MSHA Approval - United States
