Pedestrian positioning device and method based on radio frequency identification (RFID)

Abstract

The invention discloses a pedestrian positioning device and a pedestrian positioning method based on radio frequency identification (RFID). The device comprises a central management server and information acquisition units respectively arranged in monitoring sub-regions, wherein each information acquisition unit comprises at least one RFID acquisition module; and each RFID acquisition module comprises a wireless data processing terminal and an RFID reader-writer. The method comprises the following steps of: 1) dividing a region to be monitored into a plurality of monitoring sub-regions; 2) arranging the central management server and the RFID reader-writers, establishing an RFID tag information base of the central management server, and associating the RFID reader-writers with the corresponding monitoring sub-regions; 3) acquiring RFID tag information carried by pedestrians in the monitoring sub-regions in real time by the RFID reader-writers; and 4) generating pedestrian positioning data in the region to be monitored in real time, and outputting a historical moving trace of an appointed pedestrian to a user. The device and the method have the advantages of reliable system performance, relatively low cost, convenience in mounting and wide application range, and the pedestrians can be positioned in real time.

Description

technical field [0001] The invention relates to the technical field of pedestrian positioning in a designated space, in particular to an RFID-based pedestrian positioning device and method. Background technique [0002] At present, in the field of pedestrian positioning technology, a relatively mature pedestrian positioning method uses GPS technology to implement positioning of pedestrians by collecting geographic location information sent by GPS devices carried by pedestrians. But there is following shortcoming in this pedestrian positioning method that adopts GPS technology: 1, because the structure in the designated space is complicated, and the error of GPS information itself is bigger, therefore cause the location information accuracy not enough, for the pedestrian in the designated space Positioning is particularly difficult and adaptability is poor. 2. Due to the high cost of dedicated GPS equipment, a large number of dedicated GPS equipment is often required to real...

But there is following shortcoming in this pedestrian positioning method that adopts GPS technology: 1, because the structure in the designated space is complicated, and the error of GPS information itself is bigger, therefore cause the location information accuracy not enough, for the pedestrian in the designated space Positioning is particularly difficult and adaptability is poor

2. Due to the high cost of dedicated GPS equipment, a large number of dedicated GPS equipment is often required to achieve pedestrian positioning in a designated space, resulting in high cost of the entire system
