Problems solved by technology

[0003] With the development of Internet of Things technology, RFID technology has also made great progress. At present, satellite positioning is the main outdoor positioning technology, but the satellite signal is greatly attenuated by the influence of buildings, and the positioning accuracy is also reduced. Therefore, RFID-based indoor positioning technology
[0004] The current RFID positioning accuracy is low, usually only through the card reader to achieve regional positioning

Abstract

The invention relates to the technical field of positioning, in particular to an experimental device based on an RFID and satellite positioning system. The experimental device comprises a satellite positioning module, a 2.4G radio frequency master read-write module, a serial port communication module and a plurality of 2.4G active reference tags which are arranged in a distributed mode. The 2.4G radio frequency master read-write module is electrically connected with the data port of the satellite positioning module and the data port of the serial port communication module. The 2.4G active reference tags are connected with the 2.4G radio frequency master read-write module and a 2.4G radio frequency slave read-write module through wireless radio frequency. Through combination with the advantages of satellite positioning and RFID positioning, the reference tags are used, and therefore RFID positioning accuracy can be improved; the slave read-write module is used in the further technical scheme, and therefore the positioning range can be enlarged, and positioning accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to an experimental device based on RFID and a satellite positioning system. Background technique [0002] The Internet of Things refers to connecting any item with the Internet through radio frequency identification, infrared sensors, global positioning systems, laser scanners, gas sensors and other information sensing devices according to the agreed agreement for information exchange and communication, so as to realize A network for intelligent identification, positioning, tracking, monitoring and management. As the core course of the Internet of Things engineering, the sensor network has attracted more and more attention to the construction of the course. [0003] With the development of Internet of Things technology, RFID technology has also made great progress. At present, satellite positioning is the main outdoor positioning technology, but the satellite signal is greatly ...
