Embodiment Construction

[0023] Embodiments according to the present invention will be described in detail below with reference to the accompanying drawings.

[0024] In order to better understand the present invention, at first some commonly used terms are explained:

[0025] Radio Frequency Identification (RFID) technology: It is a wireless communication technology with short distance, low power consumption and high data rate. It uses radio frequency to conduct non-contact two-way communication to exchange data to achieve the purpose of identification and positioning. This technology can obtain centimeter-level precision positioning information within a few milliseconds, and has a large transmission range and low cost.

[0026] Working principle of RFID system: The most basic RFID system consists of electronic tags, readers and miniature antennas that transmit radio frequency signals between tags and readers. When the tag is placed near the fixed-frequency electromagnetic field emitted by the card...

Abstract

The invention provides a positioning system which comprises a data control module, a reader-writer, one or more radio-frequency labels and a server. The data control module is arranged in belongings of a user, used for storing a user ID and sending a read-write instruction to the reader-writer, wherein the user ID represents the identity of the user, the reader-writer is arranged in belongings of the user and used for sending a read-write signal through a first radio-frequency signal according to the read-write instruction, one or more radio-frequency labels are distributed in a preset region and used for receiving a radio-frequency label of the read-write signal and sending a stored label ID to the reader-writer through a second radio-frequency signal, the label ID represents the position of the radio-frequency label, the server is used for confirming the ID and the position of the user according to new data from the data control module, and the received label ID is sent by the reader-writer to the data control module which is used for processing the user ID and the label ID are processed into new data and sent the user ID and the label ID to the server. By the technical scheme, the rapid and effective positioning system aiming at the family environment is realized.

Description

technical field [0001] The present invention relates to indoor positioning technology in the technical field of telecommunication, in particular, to a positioning system based on radio frequency identification technology (Radio Frequency Identification, hereinafter referred to as RFID). Background technique [0002] The smart home industry has developed rapidly in the past two years, and more and more smart houses and smart communities have emerged as the times require. While consumers choose traditional sanitary ware and lamps, they also begin to pay more attention to the demand for smarter and more humanized services. User identification and positioning are the basis for the implementation of the smart features of smart homes. [0003] In the field of indoor positioning, existing implementation methods include ultrasonic return time difference method, radio wave interference positioning method, Wi-Fi-based positioning method, and indoor positioning method based on RFID te...
