Abstract:
The present invention relates to a fall detection method and system. The fall detection method comprises: receiving, by a first receiving antenna, a first WiFi signal stream propagating through an environment; receiving, by a second receiving antenna, a second WiFi signal stream propagating through the environment; determining a physical layer Channel State Information (CSI) stream, namely, a first CSI stream, of the first WiFi signal stream; determining a physical layer CSI stream, namely, a second CSI stream, of the second WiFi signal; determining a phase difference, namely, a CSI phase difference, between respective phase of the physical layer CSI stream of the first WiFi signal stream and the physical layer CSI stream of the second WiFi signal stream at the same time point, to form a CSI phase difference stream; and determining, according to the CSI streams and the CSI phase difference stream, a fall event.
