Abstract
An identification method comprising: when an object is in a whole process from entering to separating from a region inducted by the low-frequency electromagnetic field, receiving the low-frequency signal of the low-frequency electromagnetic field in real time; extracting the attribute code and signal intensity corresponding to the low-frequency signal received and conducting associate storage; and after the object separates from the region inducted by the low-frequency electromagnetic field, determining the route direction along which the object passes through the vector beacons according to the attribute code and signal intensity stored.
