Problems solved by technology

The multi-address anti-collision algorithm is at the cost of increasing the complexity and cost of the system, and has insurmountable defects; the ALOHA anti-collision algorithm sometimes causes the reader to make a wrong judgment, whether a tag is within the read-write range or not. Misjudgment, and there is also the problem of high collision probability; simple binary anti-collision algorithm sometimes cannot achieve good collision avoidance effect

Abstract

The invention provides a radio frequency positioning system with a learning capability and a positioning method thereof, and relates to the technical field of positioning. The radio frequency positioning system is characterized in that the system comprises a label node, a coordinate reader-writer, a gateway node, a mobile end and a cloud end; the label node comprises a label controller and a label radio frequency transceiver module; the reader-writer comprises a reading-writing storage and calculation module, a reading-writing controller and a reading-writing radio frequency transceiver module; the gateway node comprises a communication interface, a micro-processor and a gateway radio frequency transceiver module; the cloud end comprises a cloud end analysis processor, a cloud end database and a cloud end data transmission module; and the mobile end comprises a mobile end data transmission module, a processor and an operation interface. The radio frequency positioning system has the advantages that the cost is low, the positioning is accurate, the algorithm trap is avoided, the learning capability is realized, and the practicability is high.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to a radio frequency positioning system and a positioning method with learning capability. Background technique [0002] With the development of society, positioning technology is getting more and more attention. Existing positioning technologies such as GPS positioning, infrared positioning, etc., have certain limitations in terms of accuracy, cost, and feasibility, especially in the case of local positioning blocked by some shielding objects. Radio frequency identification (RFID) positioning technology has become an important technology choice in this situation due to its advantages of non-contact, high sensitivity and low cost, and has attracted more and more attention. [0003] In a multi-tag positioning system, there will inevitably be a situation where multiple tags communicate with the reader at the same time to generate signal collisions. At present, there are many ki...
