W artykule omówiono dwa rodzaje opracowanych w CIOP-PIB systemów umożliwiających identyfikację upadku człowieka z wysokości. Działanie pierwszego z nich jest oparte na akcelerometrycznym układzie pomiarowym, zaimplementowanym w pasie biodrowym, który stanowi element sprzętu zabezpieczającego przed upadkiem z wysokości. Działanie drugiego systemu polega na analizie zarejestrowanego obrazu wideo. Przedstawiono metody oraz wyniki badań kalibracyjnych i sprawdzających obu zaprojektowanych systemów, które wykorzystano do przeprowadzenia badań wstępnych. Podczas tych badań uczestnik wykonywał określone ćwiczenia: siadanie i symulowany upadek. Porównanie wyników badań wykazało dużą zbieżność pomiędzy wartościami zmierzonymi za pomocą czujników przyspieszeń oraz wartościami uzyskanymi na podstawie przeprowadzonej analizy obrazu. Opisane systemy mogą więc posłużyć do identyfikacji upadku oraz jako elementy inicjujące urządzenia do dynamicznego skracania drogi spadania, które zmniejszą siły działające na człowieka podczas powstrzymywania jego spadania z wysokości.

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 identification 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.
