Non-inductive channel intelligent networking identification system

Abstract

The present invention provides a non-inductive channel intelligent networking identification system, including: a plurality of signal detection devices for identifying radio frequency tags, each signal detection device includes two antennas for completing spatial signal coverage; wherein, the first The signal detection device is deployed on both sides of the longitudinal axis of the longitudinal channel space with its two antennas; the second signal detection device is deployed in the transverse channel space perpendicular to the longitudinal channel space, and its first antenna is arranged in the space of the longitudinal channel. In the intersecting space of the longitudinal channel space and the transverse channel space, and facing the two ends of the longitudinal axis, the signal is covered; the control device is electrically connected with each signal detection device, so as to control it to implement signal coverage to read / write the radio frequency tag. In this application, the coverage relationship of the antennas of multiple signal detection devices defines the entry and exit passages that the radio frequency tags must pass through. Through the entry and exit passages, non-contact and non-inductive radio frequency label identification can be realized, missing readings can be avoided, and identification efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of radio frequency, in particular to a non-inductive channel intelligent networking identification system. Background technique [0002] In recent years, with the large-scale construction of the Internet of Things, intelligent life has gradually become popular, daily life activities have been simplified, and various activities in life have gradually become self-service without feeling, such as shopping without feeling and borrowing and returning books without feeling. Senseless shopping means that people can complete the shopping settlement without going through a salesperson or a self-service vending machine after they get the goods directly from the store; the senseless borrowing and returning of books means that people get a book from the library and directly use the book. When you take it out of the library, you can directly complete the borrowing operation without going through the borrower or s...

AI Technical Summary

Problems solved by technology

The RF antennas in shopping malls or libraries are generally evenly distributed indoors in the form of a dot matrix, but due to the density of the RF antenna layout, different problems will be caused

When the radio frequency antennas are sparsely arranged, each radio frequency antenna needs to be responsible for a large space range. If the number of people within the area of ​​the radio frequency antenna is too dense, it will be difficult for the individual radio frequency antennas mentioned above to detect dense areas. Make accurate judgments on all operations done by personnel

However, when the RF antennas are densely arranged, the number of RF antennas required is large, so the layout cost of RF antennas in shopping malls or libraries will rise sharply, and the economic pressure will increase.

Moreover, the radio frequency antenna takes its position as the center of the circle, radiates signals to a circular area, and radiation blind areas may be formed between the radiation ranges of multiple radio frequency antennas that are sparsely arranged, and the radio frequency tags in the radiation blind areas cannot be successfully read. Pick

[0006] In shopping malls or libraries, people usually pick goods or books, and often pick up or put down goods or books, which will cause the radio frequency antenna to identify the goods that do not need to be purchased or the books that need to be borrowed, resulting in the radio frequency antenna It will identify people's invalid choices, increase the working pressure of the radio frequency antenna, and increase the calculation pressure of the entire database
