System and method for preventing fall accidents at building construction sites and shipyard

摘要

The present invention is provided with a laser detector 120 for detecting the movement of an object in an elevator hall 400 of a building under construction and a space 402 outside the building under construction, which is a fallable space, respectively, and the elevator hall 400 A method of operating any one of a plurality of air mats at a building construction site in which a cover 131 having a movement sensor 130 is further provided in the opening 401 of the (a) control module Step (S10) the receiving unit 210 of (200) receiving the vertical displacement information of the operator (111) from the displacement sensor (110); (b) the receiving unit 210 of the control module 200 receiving the detection information of the laser detector 120 (S11); (c) the receiving unit 210 of the control module 200 receiving the fixed value change information of the movement sensor 130 (S12); (d) the control unit 220 of the control module 200, each of the information received by the receiving unit 210 in the steps (a), (b), (c) falls within a preset reference range for each determining whether or not (S20); (e) repeating steps (a) to (d) at a predetermined cycle (S30); and (f) the controller 220, when at least one of the information received by the receiver 210 in steps (a), (b), and (c) is out of a preset reference range for each, a plurality of It relates to a method, comprising the step (S40) of operating any one of the air mats 301 of the air mats.
