SYSTEMS AND METHODS FOR DETECTING PATTERNS IN SPATIO-TEMPORAL DATA COLLECTED USING RFID SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide systems and methods suitable for detecting patterns in spatio-temporal data collected using an RFID system.;SOLUTION: Systems and methods are described that collect spatio-temporal data using an RFID system that is capable of locating the spatial position of a sensor, which is typically unaware of its location. One embodiment includes an RFID system having a plurality of read zones and configured to obtain the spatio-temporal state of sensors within a sensor cloud, where the spatio-temporal state of each sensor includes sensor information, a time stamp, and a spatial location specified independently of the read zones of the RFID system, a spatio-temporal database configured to store spatio-temporal state of a plurality of sensors over time, and an application server.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
