Abstract

An indoor positioning device and a positioning method based on small radar and ID recognition are provided. The positioning device includes a user terminal device disposed on a positioned object and a fixed-terminal device disposed on a positioning point. The user terminal device is provided with an RFID label or an ID identifier A; the fixed-terminal device is provided with an RFID reader or an ID identifier B, and the RFID reader or the ID identifier B is in communicative connection with the RFID label or the ID identifier A. The fixed-terminal device also has a low-frequency wake-up for waking up the user terminal device and a radar for obtaining the current position information of the user terminal device. According to the invention, the RFID technology is combined with a radar, realizing the accurate determining of the position information of a positioned object. Low in cost, the device and the method cause small errors.

Description

technical field [0001] The invention relates to an indoor positioning device based on small radar and ID identification. Background technique [0002] For more than 20 years, indoor positioning has been trying to find solutions in the technical system of communication, including power line carrier-assisted positioning, etc., but there are still shortcomings such as poor positioning accuracy and high cost. Contents of the invention [0003] In view of the above shortcomings, the present invention provides an indoor positioning device and positioning method based on small radar and ID identification. By combining RFID technology with radar, the position information of the positioned object can be accurately determined, with low cost and small error. [0004] The technical solution of the present invention: an indoor positioning device based on small radar and ID identification, characterized in that it includes a client device set on the object to be positioned and a fixed t...
