Pseudo base station rapid positioning method and system based on offline fingerprint database

The invention relates to a pseudo base station rapid positioning method and system based on an offline fingerprint database. The pseudo base station rapid positioning method comprises an offline archiving step: constructing a position-reference point feature fingerprint database according to the mapping relation between the position information of each reference point and RSS positioning feature information in an area to be monitored; and an online judgment step: sampling the RSS positioning feature information in the area to be monitored, comparing the sampled RSS positioning feature information with information in the position-reference point feature fingerprint database and looking up the position information of a pseudo base station. Compared with an existing pseudo base station positioning scheme, the method provided by the invention has the advantages of small positioning error, low hardware condition limitation, wide coverage range, high system total accuracy and very high practical application value.
