FALL DETECTION DEVICE, FALL DETECTION UNIT, FALL DETECTION SYSTEM, AND FALL DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an abnormality occurrence detection method which is capable of detecting the occurrence of abnormality regardless of indoor and outdoor situations and has a wide measurement area, high measurement accuracy, excellent power-saving property and portability, and sufficient capability of responding to an emergency.

SOLUTION: A fall detection device 4 is a device which is used by being carried or worn by a person to be detected and comprises: a triaxial acceleration sensor 1A for detecting acceleration on the basis of a movement of the person to be detected such as walking; a triaxial angular velocity sensor 1B for detecting angular velocity on the basis of a movement of the person to be detected such as walking; signal processing means 2 for processing respective sensor signals from the triaxial acceleration sensor 1A and the triaxial angular velocity sensor 1B; and communication means 3 which is capable of transmitting a processed signal obtained by the signal processing means 2 to the outside.
