Abstract

The invention relates to an indoor positioning system based on an RFID technology, comprising an active RFID tag, an RFID card reader, a CAN bus, a switch, an Ethernet network and a computer, wherein the computer is provided with an intelligent positioning module; the active RFID tag is provided with an identifier and sends the identifier at a regular time; the RFID card reader reads an identifier signal and measures signal intensity; the identifier signal and the signal intensity are transmitted to the switch by the CAN bus; the switch gathers the received data which is transmitted to the computer by the Ethernet network; the intelligent positioning module in the computer analyzes the identifier signal intensity by an equivalence position calculation model built by a neural network to output the equivalence position class. Compared with the prior art, the invention has the advantages of low cost, high precision, high adaptability and the like.

Description

technical field [0001] The invention relates to an indoor positioning system, in particular to an indoor positioning system based on RFID technology. Background technique [0002] Radio frequency identification technology (RFID, the abbreviation of Radio Frequency Identification) is to use radio waves to identify and read and write targets. Compared with other identification technologies, such as bar codes and voice recognition, the biggest advantage of using RFID technology is that no human intervention is required. The RFID reader will automatically obtain the data on the RFID tag and transmit it to the computer system for further application. In the past ten years, RFID technology has achieved rapid development and is widely used in supermarkets, logistics, management and other fields. It is considered to be one of the most promising information technologies in the 21st century. [0003] RFID positioning is to use RFID technology to track the location of the target obje...
