A novel RFID tag positioning method based on mobile RFID reader and vehicle-mounted GNSS

It causes lots of trouble for the managers in the department of urban management to manage the urban components because of the mobility of some urban components such as breakfast cart, stalls, and newsstands. To resolve this problem, the key issue is that how to get locations of these components rapidly and conveniently. Although, GPS is the popular positioning system used in the outdoors, urban buildings and other objects, such as trees, weaken the GPS signal and decrease the positioning precise. With the Internet of Thing (IOT) development, RFID is a better way for locating. In traditional applications, many RFID readers or reference tags must be deployed to being a network for calculating coordinates of target objects. This has pitfalls of poor application in urban complex environment, expensive cost, and difficulty to maintenance. This paper presents a new method based on mobile RFID reader and vehicle-mounted Global Navigation Satellite System (GNSS) to locate the mobile urban components. The method needs RFID tag pasted on mobile urban component. The cost is lower in this way. When the tag falls within the detecting range of RFID reader, the coordinate can be calculated immediately. This kind of collaboration locating is a novel method for positioning by combining mobile RFID reader and vehicle-mounted GNSS. An experiment is conducted and proved that this proposed approach is valid for positioning of mobile urban components.
