mmWave IWR - safety guards

Discover

With factories  becoming smarter, man and machine work “hand in hand”. In this scenario, to reduce possibility of  potential hazards if there is a flaw or bug in automation, incident management through Safety Guards is becoming important. TI’s Industrial mmWave sensors can be used for high accuracy occupancy detection and collision avoidance, where the position and velocity of people can be used to trigger systems when a person or an object is in proximity of a machine.

Check out these documents below to learn the basics of mmWave sensors for Safety Guards.

Application benefits
Range resolution 4cm 4cm 4GHz bandwidth provide higher range resolution to separate objects in close proximity.
Angular resolution 15º  15º  Low angular resolution allows distinguishing small details of an object.
Max. range (resolution) 10m (0.12m) 10m (0.15m) Used as and Area Scanner or an Arm safety curtain to maintain a no-entry curtain or zone radially around the equipment.
Max. field of view (resolution) 120º  (15º angular resolution) 120º  (15º angular resolution) Wider area detection and tracking of multiple moving objects as people for incident management.
Static clutter removal Yes Yes Allows non-moving objects to be filtered out to give true detection of people or vehicles.
