PROCÉDÉ ET APPAREIL D'ALERTE PRÉCOCE BASÉE SUR UNE PERTURBATION DE LA FORCE DE SIGNAUX WI-FI, ET SUPPORT DE STOCKAGE

摘要

The present disclosure provides an early warning method and an early warning device based on WIFI signal strength disturbance, and a storage medium. The early warning method includes receiving and analyzing WIFI signals in a monitoring area in real time to obtain amplitude and phase of a current WIFI signal in the monitoring area; determining whether the amplitude and the phase of the current WIFI signal are disturbed according to a difference between the amplitude and the phase of the current WIFI signal and those of a previous WIFI signal; and sending out an early warning signal when it is determined that the amplitude and the phase of the current WIFI signal are disturbed.
