Factories, manufactoring plants and onloading/offloading zones are dangerous environments to work by their nature. Forklifts, heavy duty carrying vehicles and humans share the same – sometimes really tight – space during everyday operations. Proximity aims to eliminate or minimize accidents that involve humans and vehicles in these floors. Each person carries a location device on themselves which is embedded to their security vest. All vehicles are fitted with a special hardware which interface to industry standard CAN bus of the vehicle. Proximity system captures the positions of each person and vehicle iterating this 30 times a second. In case trajectory of a vehicle intersects with a human, system automatically issues audial and visual alerts of the danger. In case trajectories still intersect, Proximity system issues a shut down command to vehicle to avoid contact with humans. Position, speed and direction information is available on a virtual map as well as heatmaps.
