Method for generating at least one fixed spatial danger zone to be avoided in a space, using at least one generation system worn by a pedestrian and comprising at least locating means and electronic management means, which generation method successively comprises at least: i. a step of the electronic management means sending a command triggering the acquisition of the spatial coordinates of the generation system to the locating means; ii. a step of the electronic management means determining an outline of determined shape and dimensions delimiting the fixed spatial zone on the basis of the spatial coordinates of the generation system acquired by the locating means, and recording the spatial coordinates defining said outline in a memory space of the electronic management means; iii. a determination and recording step consisting in detecting the fixed spatial zone and/or a mobile spatial zone by means of the generation system capable of detecting such a spatial zone (2, 13), this step comprising the successive sub-steps of: a. the locating means periodically determining the position coordinates of the system, and the electronic management means periodically determining the spatial coordinates of the mobile zone and the distance between said position of the generation system and said mobile spatial zone and/or the fixed spatial zone; b. when the distance determined in the preceding sub-step is smaller than a predetermined distance recorded in the memory space of the management means, a warning device of the generation system issuing a warning signal; iv. a step of the electronic management means determining the possible trajectories (9, 60-64) of the generation system and/or of the mobile spatial zone on the basis of their respective spatial coordinates, then determining a probability of collision between the generation system and the mobile spatial zone and/or the fixed spatial zone. i. a step of the electronic management means sending a command triggering the acquisition of the spatial coordinates of the generation system to the locating means; ii. a step of the electronic management means determining an outline of determined shape and dimensions delimiting the fixed spatial zone on the basis of the spatial coordinates of the generation system acquired by the locating means, and recording the spatial coordinates defining said outline in a memory space of the electronic management means; iii. a determination and recording step consisting in detecting the fixed spatial zone and/or a mobile spatial zone by means of the generation system capable of detecting such a spatial zone (2, 13), this step comprising the successive sub-steps of: a. the locating means periodically determining the position coordinates of the system, and the electronic management means periodically determining the spatial coordinates of the mobile zone and the distance between said position of the generation system and said mobile spatial zone and/or the fixed spatial zone; b. when the distance determined in the preceding sub-step is smaller than a predetermined distance recorded in the memory space of the management means, a warning device of the generation system issuing a warning signal; a. the locating means periodically determining the position coordinates of the system, and the electronic management means periodically determining the spatial coordinates of the mobile zone and the distance between said position of the generation system and said mobile spatial zone and/or the fixed spatial zone; b. when the distance determined in the preceding sub-step is smaller than a predetermined distance recorded in the memory space of the management means, a warning device of the generation system issuing a warning signal; iv. a step of the electronic management means determining the possible trajectories (9, 60-64) of the generation system and/or of the mobile spatial zone on the basis of their respective spatial coordinates, then determining a probability of collision between the generation system and the mobile spatial zone and/or the fixed spatial zone.
