Sudden disaster judging method based on mobile terminal WiFi position data

Abstract

The invention relates to a sudden disaster judging method based on mobile terminal WiFi position data. The method comprises steps: S100, according to the mobile terminal WiFi position data, the mobileterminal networking amounts [SN1, SN2, ... , SNr] and [PN1, PN2, ... , PNr] in r unit areas [N1, N2, ... , Nr] contained in a preset area within a first preset time period [t-T, t] and a second preset time period [t, t+T] are acquired, wherein T is larger than 0, SNi is the mobile terminal networking amount in a unit area Ni in the first preset time period [t-T, t], PNi is the mobile terminal networking amount in a unit area Ni in the second preset time period [t, t+T], and 1</=i</=r; S200, based on [SN1, SN2, ... , SNr] and [PN1, PN2, ... , PNr], networking signal abrupt change values [P1, P2, ... , Pr] of [N1, N2, ... , Nr] at the moment t are acquired, wherein Pi is the networking signal abrupt change value of the unit area Ni at the moment t; and S300, if M Pis are larger than a firstjudgment threshold, the preset area is outputted as a sudden disaster place, wherein M is no smaller than 1.

When an earthquake occurs, the projection point of the source on the surface detected by the seismic network equipment is the micro-epicenter. Due to differences in geological conditions and crowd gatherings, the micro-epicenter is not the most severely damaged area in many cases; in order to quickly obtain the earthquake impact field The distribution, size, location, and direction of the earthquake are obtained by conventional methods based on h
