Systemy umożliwiające identyfikację upadku z wysokości

Abstract

The article discusses two types of systems developed at CIOP-PIB, which enable the identification of human falls from a height. The operation of the first system is based on an accelerometric measuring system implemented in the hip belt, which is an element of the equipment protecting against falls from a height. The operation of the second system is based on the analysis of the recorded video. The methods and results of calibration and verification tests of both designed systems, which were used for the preliminary tests, were presented. During these tests, the participant performed specific exercises: sitting down and simulating falling. The comparison of the test results showed a high convergence between the values measured with the acceleration sensors and the values obtained on the basis of the image analysis. The described systems can therefore be used for fall dentification and as initiators of devices for dynamic shortening of the fall path, which will reduce the forces acting on a person during restraining his fall from a height.
