Abstract

The invention relates to an indoor positioning tracking system and an indoor positioning tracking method based on a passive radiofrequency identification technology. The system consists of a central controller, a router, a wireless router, an all-in-one electronic tag reader-writer, an antenna and a passive tag. The method comprises the following operating steps of: (1) laying out an antenna array; (2) managing entrance and exit of personnel; (3) performing a positioning tracking algorithm; and (4) displaying positioning tracking. Due to the adoption of the system and the method, positioning tracking of dynamic targets such as human beings, animals, objects and the like in rooms can be realized; and the system can work in a severe environment, so that a base is laid for a position-based service. The system has advantages of simple structure and low cost; and the method is easy and convenient to operate, and is superior in performance, and is suitable for large-scale indoor positioning and tracking occasions.

Description

technical field [0001] The invention relates to an indoor positioning and tracking system and method, in particular to an indoor positioning and tracking system and method based on passive radio frequency identification technology. Background technique [0002] With the continuous development of wireless network, computing technology and Internet of Things technology, people's demand for ubiquitous services is increasing. In the process of building a smart city, building a high-precision location service platform is one of the important topics. It can be seen that location-based services are becoming more and more important. Location-based services are services based on geographic location data, so positioning technology is the key. [0003] At present, positioning systems can be divided into outdoor positioning and indoor positioning according to the positioning environment. Outdoor positioning mainly includes Global Positioning System (GPS, Global Positioning System) and ...
