The invention discloses a wearing type dynamic real-time fall detection method and device. The wearing type detection device comprises a specific hardware structure consisting of a foot part, a waist part, a wrist part and a back part. According to the dynamic real-time fall detection method, real-time judgment of the fall of human body in any state can be finished. The core algorithm of the detection device comprises a threshold opening logic structure caused by sudden change of gait acceleration, a human body posture dynamic stability judgment algorithm based on zero moment point (ZMP), and a fall mode identification algorithm based on a human body motion database. A complete dynamic real-time detection system is constructed, and the aims of wide application field, low dependence on the application environment and real-time detection are fulfilled. Moreover, the detection method and the detection device are high in accuracy, and have the advantages of low system cost, small system size and good convenience in wearing.
