time-domain analysis and fuzzy logic to determine device using gait freezing and freeze it by walking It discloses a detection method. Time-domain analysis and gait freezing apparatus using a fuzzy logic to determine a three-axis acceleration sensor for outputting a three-axis acceleration signal corresponding to the movement of the pedestrian (110); After extraction of the acceleration signal of each axis from the three-axis acceleration signal, the acceleration signal of each axis of the RMS group within the set time interval (Root Mean Square) RMS calculation unit for calculating a value (120); And the calculation unit of the respective axis acceleration signal calculated by the (120) RMS (Root Mean Square) membership for each axis value and a predetermined function (membership function) as compared to the determination to determine a walking state of the walker unit 130; The membership function (membership function) algorithm is stored, a storage unit for storing the comparison result of the determining unit (130, 150); And a communication module 140 that transmits a determination signal to the outside via the air interface according to the result value, the determination unit 130 is a stable state of the pedestrian according to the comparison result, the normal walking state, walking freezing (FOG) is characterized in that to determine the status. ;
