Issue

As Autonomous Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs) become increasingly common in warehouses and smart factories, ensuring worker safety remains a critical challenge. Employees may unintentionally walk into the path of a moving AGV, especially in busy environments with limited visibility or high noise levels. Without a clear warning system, this can lead to near misses, operational disruptions, or workplace accidents.

Solution

The PATLITE LKEH Combination Signal Tower provides highly visible LED indications and powerful audible alerts to improve safety around AGVs.

Installed directly on the AGV, the LKEH continuously communicates the vehicle's operating status through its three-color LED signal tower:

• Green Light: Normal AGV operation
  
• Red Flashing Light: Human detected near the AGV
  
• Voice Announcement: "Warning, please be careful"
  
• Integrated Horn: Additional audible warning for increased awareness
  

When a worker approaches the AGV, the vehicle automatically slows down while the LKEH activates visual and audible alerts. This immediate notification helps nearby personnel recognize potential hazards and move to a safe distance.

Summary

The PATLITE LKEH enhances workplace safety by providing clear visual, audible, and voice warnings for AGV applications. By alerting workers when they are near a moving AGV, the system helps reduce collision risks, improve situational awareness, and support safer material handling operations in warehouses, distribution centers, and smart factories.
