The invention discloses a passenger flow track tracking method, device and system, relating to the technical field of wireless communication. The method comprises the following steps: receiving mobileterminal identity identification information transmitted by a plurality of WIFI sensing devices, identity identification information of the WIFI sensing devices, and timestamp information of a mobileterminal detection packet received by the WIFI sensing devices, wherein a mobile terminal periodically transmits the detection packet to the WIFI sensing devices; determining relative position coordinates of the WIFI sensing devices based on the identity identification information of the WIFI sensing devices; identifying the mobile terminal based on the mobile terminal identity information; according to the moving speed of the mobile terminal, the relative position coordinates of the WIFI sensing devices and the timestamp information, determining relative position coordinates of the mobile terminal at different time p
