Embodiment Construction

[0017] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] like figure 1 As shown, in an embodiment of an RFID base station unit for indoor positioning of the present invention, the RFID base station unit includes a plurality of RFID readers and a control unit, and the control unit controls the plurality of RFID read-write The device sends data requests respectively, so that the RFID electronic tags within the scope of action respond; after the RFID reader receives the signal returned by the RFID electronic tag, it obtains the data carried in the returned signal and transmits it to the control unit; The control unit processes the data transmitted by at least two RFID readers to obtain location information and upload it to the server through the network. In this embodiment, the above-mentioned control unit provides a plurality of RFID reader-writers with a power supply or a control signal to turn on or of...

Abstract

The invention relates to an RFID base station unit for indoor positioning. The RFID base station unit comprises a plurality of RFID readers / writers and a control unit. The control unit controls the plurality of RFID readers / writers to send data requests, and RFID electronic tags in an influence range carry out response; after the RFID readers / writers receive signals returned by the RFID electronic tags, data carried in the signals is read and transmitted to the control unit; and the control unit processes the data sent by the at least two RFID readers / writers to obtain positioning information and uploads the positioning information to a server through a network. The RFID base station unit for indoor positioning provided by the invention has the following beneficial effect that the relatively accurate positions of the RFID electronic tags in the influence range of the RFID base station unit can be determined relatively accurately.

Description

technical field [0001] The present invention relates to the field of radio frequency identification, and more specifically, relates to an RFID base station unit for indoor positioning. Background technique [0002] For personnel or equipment positioning, if it needs to be carried out in a large area or in the field, in most cases, GPS or Beidou system can solve it well, and configuring the positioning terminals of the above two systems for personnel or equipment can realize almost all It can receive the positioning of the satellite signal position, and the positioning position is relatively accurate. However, in places where satellite signals cannot be received, satellite signals are poor, or locations overlap, for example, in the lobby of a building or in a space with overlapping locations in a tall building (for example, multiple spaces that overlap in height), the above positioning methods cannot Positioning, or even barely positioning, works very poorly. In some cases,...
