First Claim
1. A fall detection method performed by a fall detection server, the fall detection method comprising:
- receiving electricity information from a piezoelectric plate through a gateway, the piezoelectric plate being disposed adjacent to a bed of a subject;
performing a primary determination of whether or not the subject fell from the bed based on the electricity information;
transmitting a first control signal to a microphone through the gateway if it is determined that the subject fell, thereby triggering the microphone to collect audio information which includes sound generated around the subject and a voice of the subject, the first control signal being generated according to a result of the primary determination;
receiving the audio information from the microphone through the gateway;
performing a secondary determination of whether or not the subject fell based on the audio information;
transmitting a second control signal to an imaging device through the gateway if it is determined that the subject fell, thereby triggering the imaging device to capture an image of a current state of the subject, the second control signal being generated according to a result of the secondary determination;
receiving video information from the imaging device through the gateway, the video information including the image of the current state of the subject; and
transmitting fall information relating to a fall of the subject to a protector terminal of the subject, the fall information including one or more of the primary determination result, the secondary determination result, trigger information of the imaging device, and the video information,wherein the piezoelectric plate is arranged on a floor surface around the bed, andwherein the gateway is coupled to and disposed between the fall detection server and the piezoelectric plate, between the fall detection server and the imaging device, and between the fall detection server and the microphone.
