The present invention concerns a motorized door comprising an array of n detection cells distributed along the length of the leading edge, capable of detecting the presence and distance, Δx, from said detection cell of a body positioned between said detection cell and a distal transverse edge. The detection cells are coupled to a CPU which triggers different actions during the closing of the shutter, depending on the proportion, P = n 1 / n of the number, n 1, of detection cells identifying the presence of a body at a same time located at a distance, Δx ≤ Δxs, wherein Δxs is a predefined safety distance. (a) if P ≤ Ps, wherein Ps is a predefined safety proportion, the detected body is considered as an accidental obstacle and the CPU is programmed to instantly stop the movement of the shutter; (b) if P > Ps, the CPU considers that the detected body is a distal transverse edge defining the end of the closure run, and orders to decrease the closing speed of the shutter until the leading edge contacts the distal transverse edge. |
