Radio frequency identificatio♠"≥λn is a non-contact a♦≠→‌utomatic identification technol↔>ogy. The specific worki$Ω₽∞ng principle is as follows: when an o•§bject equipped with an electroni•δ§"c tag approaches the microwave antennεσ←a, the reader is controlled to sen ✔€d out a microwave inq©‍βγuiry signal. After the electroni≈≈$c tag installed on thε®★e surface of the object receives the query sig₹'∏nal sent by the microwave a∞α♣ntenna, it reflects the data in×↑∑™formation in the tag back to the microwave antenn≤λa according to the command requirements in the ₽↕≥↑query signal. After the micδ∞"rowave antenna recei↕←♥σves the microwave synthesis signal reflectedπ÷≥∑ back by the electronic tag, the informatio∞©✔n such as the identification code in the electr'‍onic tag can be separated b♦♥y the internal microprocessor of the reader. The∞♣♥β identification information is transmitted t✘₹o the control computer a<←$¶s the characteristic data of t$₹€↓he object for further process∞₩α∞ing, so as to complete the applicaγ₹α→tion of information ​λinquiry, statistics and management related tβ₽✔♥o the object. The entire identifφ€✘ication work does not require manual interventi≥&←↓on and can work in various ha∏₽∏rsh environments. RF↕®ID technology can identify high-speed "₩∏ moving objects and can identify multiple tags a★∑↓t the same time, and the reader can determine w¥∞ ∞hether the RFID tag has been r∑✔ £epeatedly read.

The RFID system is generally composed of a readerγ↕₹ , a transponder (tag) and an application sβε¥ystem, and transmits information betwee±δn the response medium and the interrogat¥↑±♠ion medium through electric waves. The rea<< der is generally a re∏® ading (and sometimes writing) de♥±✘vice with an antenna and chip dec ↕oder. It can be designed as a handheld or fix ♦ed type; the reader ♠®→♥can read and identify the stored in t∑♠§he electronic tag without β↓contact Electronic data, ©✔so as to achieve the purpose of automa☆​‌tically identifying  ε¶♣the body. Usually the reader is conne∞≥&™cted to the computer, and t<→≥γhe read label information is transmitted to tσ βhe computer for further processing. The a&≈δpplication system is generall÷©↓y a wired or wireless management systeδγm supported by a computer. Depending on diff→€₩erent application requirements, it is noβ≥★t necessary to have a backg​'round application system for a real-time intλ≠elligent controller. Tags, mainly radio freq≤ uency tags, contain an aφ×♥ntenna in the response÷↑σ‍ end, and the two form a so-called "radar tran₹ ™₽sceiver", which exists in the form &>of cards, tags, etc.

The overall EPC network ope>≈↓<ration relies on the intervention of the RFID‌← system and network applic ¶≠ation system to enable the effective disseminati∞λ"‍on of product information. The r₹£±σeaders installed in different demand cha‍'in environments can read the produc> t data stored in the lab≠±✘el. Therefore, supply chain data can b≥↔↔e checked, updated or e©↑xchanged in a timely manner via th≥ ♥σe network.

EPC/RFID technology application

The application of the Internet of Thin  gs technology can make e-&≥commerce more powerful. It enables consu¶♠€mers to find any product in any sto™★re on the Internet, and choose it✘®α  easily. In the field of lo>∏×≥gistics, RFID electronic tags ₩ can be applied to many asp¥ α±ects such as automatic warehouse§♦↔ inventory managemen‌♣t, product logistics tracking, automat$≥<ic supply chain management, product assembly an♠✘♦÷d production management,∑♦₹ and product anti-counterfei≥©εΩting. Radio frequency identification (RFID) dev&₹ices, infrared sensors, global β∑ ∏positioning systems and other devices are π™♦combined with the Internet to form a hu÷÷ge network, so that all items can be remotel  ‌y sensed and controlled, and connected with the§→₩' existing network to form a smarter pr•λoduction Life system.

The development trend o↓∑πf the Internet of Things iδ✔ndustry

Under the background that the country vigorous✔₹→εly promotes the integ♠₹βration of industrialization and informatization, ≠₽φ®the Internet of Things wi♥≥ll be a more realistic breakthrou↓✘gh in the informatizati★↓←on process of industry a£★>nd even more industries.  λMoreover, RFID technology has∏ ₩ some closed-loop applications in multipleπ¶ fields and industries. ®§←★In these first successful cases, item informaγ ≠tion has been automatically collec¶♥ted and online, and management​← efficiency has been greatly improved. Some  ∏✔of the dreams of the Internet o₽♣ ↑f Things have been partially realized. Therefo€₹ε↕re, the embryonic form of the InteΩ÷rnet of Things is lik×<δe the early form of the Inte₩←rnet, the local area network. Although its rol≈≤e is limited, the broad prospects that it shows c✘₩ γan no longer be questioned.
