The invention provides a remote monitoring method and
system applied to children's watches, and relates to the technical field of children's watches, time axis synchronous alignment is carried out on collected multi-source heterogeneous data through an interpolation method, data
time sequence chaos caused by sampling rate differences is prevented, and then the data
time sequence chaos caused by sampling rate differences is prevented. Through
dynamic coupling calculation of a
light intensity mutation gradient and a
heart rate stress coefficient, the cooperative influence of environment change on the physiological state of the child is quantified in real time, and the physiological state of the child is determined by further combining power spectrum
centroid frequency and physiological
phase difference analysis of the motion
rhythm and logarithmic correlation of acoustic envelope frequency and GPS speed. In addition, an
acoustic propagation delay compensation mechanism is introduced, a two-factor
dynamic equation model is constructed through a time
delay cross term, and a dynamic
risk threshold generation
mechanism based on a
noise energy ratio is combined, so that the dynamic
risk threshold of the
motion intensity, the
rhythm characteristics and the acoustic scene is effectively distinguished. Effective remote monitoring on
child safety in different scenes is realized.
