Document Type and Number:
WIPO Patent Application WO/2018/107374
Kind Code:
A1
Abstract:
Provided in the embodiments of the present invention are a fall detection device, a fall detection method and an apparatus. The fall detection device comprises a transmitter and a receiver, the transmitter and the receiver being configured to communicate by means of capacitive coupling by using a human body as a transmission medium; a transmission electrode of the transmitter and a receiving electrode of the receiver form a forward loop, while a ground electrode of the transmitter and a ground electrode of the receiver form a backward loop; the transmitter is configured to generate a fall detection signal and couple the fall detection signal to the human body, and the receiver is configured to obtain a received measurement value of the fall detection signal which is transmitted by means of the human body; according to the received measurement value, a characteristic value of a fall description feature, which is used for representing a channel feature difference of the backward loop when the human body falls and does not fall, is extracted, and fall detection is performed according to the characteristic value of the fall description feature.
