Light as a Shield: The Rise of Virtual Projection Barriers

Imagine a safety wall that allows vehicles to pass right through it without leaving any scratches on the vehicle’s surface, yet stops all pedestrians in their tracks. This is what virtual projection barriers are all about.

In the busy warehouses of today, traditional steel guardrails are often seen as both good and harmful to the safety and productivity of warehouse workers. These guardrails do provide protection to the workers against the equipment that is constantly in motion within the warehouse, yet they consume valuable floor space within the warehouse, create hazards for workers as they navigate narrow aisles between the rows of storage units, and bend when struck by the forklifts that operate within the warehouse.

Enter changing light projections. High-output LED and laser sign projectors are mounted high overhead in the warehouse to display safety zones, stop lines, and pedestrian walkways on the floor.

Another aspect of visual barriers is their adaptability. Unlike steel pipes that are bolted into place, projection lines can be connected to sensors in the warehouse that detect potential hazards. For instance, if an AGV is approaching an intersection, a sensor will alert the system to change the display from a green walkway to a pulsing red “hazard box.”

Virtual barriers require little maintenance and can display bright and crisp visuals to drivers.

While a five-ton vehicle cannot be stopped by light, it is a material that will continue to be used for protective purposes. However, in certain areas of the facility, light projections can provide an additional layer of protection that is more effective than any other form of shielding.
