This detection is realised by the particular color Fluorescent Yellow which is found, today, on many working cloth.

Opposite a typical example of a person working on a site of sorting and recycling. This person is present around the conveyor belt which transports various materials towards a crusher or a press.

On the image opposite this person is seen on the conveyor belt.

The system is based on the use of one or more cameras video color scanning the dangerous working area.

The people who move on this zone are automatically detected by the system and are located in this zone.

If a person had suddenly come on a limit fixed and considered as dangerous, the system detects it automatically then cut all the machine tools, and informs the operators in the sound form (siren) and visual (gyrophare).

In the same way, if an operator had been suddenly hidden under unspecified materials (metal, wood, papers, plastic) and some is their state (wet, dry, polluted), detection acts and announces to the operators the hiding of one of their colleague under materials.

The third detection, which is more prevention of accident or to point out an anomaly on the working area, it is the indication of a problem when the personnel is in excess on the danger zone whereas only some people must be normally present (it is in particular the case at the time of visit of school for example, we make safe the zone because there is too strong crowd)
