METHOD FOR LOCATING A DEVICE INSIDE AN AREA

Method for locating a device (1) inside an area (10), comprising the steps of: (a) dividing said area (10) in a plurality of regions (11; 11a - 11i); (b) arranging a plurality of wireless transmitters (5; 5a - 5i) in said area (10), which are configured to emit a wireless signal (6; 6a - 6i) adapted to be received and interpreted by said device (1), said wireless signal (6; 6a - 6i) comprising at least one identification information (60; 61 - 64, 65 - 68) of the transmitter (5; 5a - 5i), wherein: - at least one transmitter (5; 5a - 5i) is associated with each region (11; 11a - 11i); - at any time, a transmitter (5e) of any first region (11e) of said area (10) transmits an identification information (61) different from the identification information (62 - 64) of each transmitter (5a - 5d, 5f - 5i) arranged in a different region (11a - 11d, 11f - 11i) adjacent to said first region (11e); - at least one transmitter (5a) of any first region (11a) transmits an identification information (63) equal to the identification information (61) of at least one transmitter (5c, 5h) arranged in a region (11c, 11h) different from, and not adjacent to, said first region (11; 11a-11i); and wherein a controlling system combined with said device (1) carries out the steps of: (cl) receiving a wireless signal (6; 6a - 6i) from at least one transmitter (5; 5a - 5i) of said region (11; 11a - 11i); (c2) verifying said identification information (60; 61 - 64; 65 - 68) contained in said wireless signal (6; 6a - 6i), so as to recognize said at least one transmitter (5; 5a - 5i) of which the controlling system has received a wireless signal (6; 6a - 6i); (c3) calculating in which region (11; 11a - 11i) of the area (10) the device (1) has been arranged, as a function of the identification information (60; 61 - 64; 65 - 68) contained in the received signal.
