The present invention discloses a
human body sleep multiple physical sign non-invasive distributed
optical fiber monitoring system and method. The
system comprises a mattress, a plurality of physicalsign
optical fiber optical
grating sensors, a demodulator and an upper computer; the physical sign
optical fiber optical
grating sensors comprise a plurality of distributed temperature optical
fiber optical
grating sensors, distributed pressure optical
fiber optical grating sensors and distributed
heartbeat /
respiration optical
fiber optical grating sensors; the physical sign optical fiber opticalgrating sensors are all fixedly arranged in fillers embedded between a mattress inner
bed net and a fabric inner filling material, and also keep depth on the same horizontal plane; the physical sign optical fiber optical grating sensors are connected with the demodulator, and output signals of the demodulator are transmitted to the upper computer through serial ports, so as to monitor health stateof a user during sleeping, such as physical sign parameters of
heart rate,
respiration, body temperature, etc.; and sleeping postures and
bed leaving conditions are analyzed according to pressure
field monitoring conditions of a user in a sleeping state. The distributed multi-parameter optical fiber optical grating
sensor networking realizes monitoring of information of multiple physical signs and sleep movement state.
