Problems solved by technology
If there is a lack of global location information services at this stage, it will lead to many problems: the failure of modern weapons, the failure of traffic navigation, etc., which shows the importance of positioning information
[0005] The current positioning technology is mostly used for indoor two-dimensional positioning. When expanding to three-dimensional positioning, it encounters problems such as increased deployment complexity and significantly reduced positioning accuracy.
In addition, the positioning of untagged objects is also very important, such as shopping mall positioning, unauthorized intrusion detection, etc. However, at present, this has not attracted enough attention in RFID indoor positioning

Embodiment 1
[0052] Such as figure 1 , image 3 shown.
[0053] An RFID-based indoor three-dimensional positioning platform includes a reference tag array, an antenna and a computer; the antenna is arranged above the reference tag array; the antenna is connected to the computer through a reader.
Embodiment 2
[0055] As in the RFID-based indoor three-dimensional positioning platform described in Embodiment 1, the difference is that the reference tag array is arranged on a plastic tray; the reference tag array is a square matrix of 11*11 with a tag interval of 20cm, refer to The reference labels in the label array are arranged in the same direction.
Embodiment 3
[0057] As in the RFID-based indoor three-dimensional positioning platform described in Embodiment 1, the difference is that the antenna is arranged at 3 meters above the reference tag array; the antenna is a circularly polarized omnidirectional antenna, and the beamwidth of the antenna is Greater than 70°.

The invention relates to an RFID-based indoor three-dimensional positioning platform and an application thereof. The RFID-based indoor three-dimensional positioning platform comprises a reference tag array, an antenna and a computer, wherein the antenna is arranged at the upper part of the reference tag array; the antenna is connected with a computer through a reader-writer. According to the RFID-based indoor three-dimensional positioning platform, a low-cost method capable of achieving tag target positioning and non-tag target positioning is provided; and the RFID-based indoor three-dimensional positioning platform can be applied to indoor low-cost deployment of a positioning device and can also be applied to the field of security of burglar prevention and the like.
Description
technical field [0001] The invention relates to an RFID-based indoor three-dimensional positioning platform and a positioning method thereof, belonging to the technical field of RFID indoor positioning. Background technique [0002] RFID (Radio Frequency Identity) radio frequency identification is a technology that uses the principle of electromagnetic coupling or backscatter for wireless communication and automatic identification. Since its appearance in the 1940s, it has been playing an important role in military, economic and other fields. Compared with other identification technologies, such as barcode, magnetic stripe, IC card and other technologies, RFID has the advantages of large information storage capacity, long storage time, wide adaptability to the environment, non-line-of-sight, and long operating distance. After continuous innovation by researchers in recent years, RFID system technology is becoming more and more mature, and the functions realized are becoming...
