Embodiment 1

[0044] Such as figure 1 As shown, a kind of foldable serpentine load UHF RFID electronic tag of this embodiment, this tag is to increase the electromagnetic information on the basis of the existing jewelry item label standard (DIN 58681-1Bb.1-1981) in the gold jewelry industry Storage function, that is, the RFID antenna structure (the non-foldable second substrate part 2 and the foldable second substrate part 3) is fabricated on the foldable first substrate part 1 by an etching method or a screen printing process, and On the second substrate part 2, the chip label is fixed on the part 2 by RFID chip binding equipment, and finally double-sided adhesive is applied on the surface of the part 1 for post-adhesion purposes. For the convenience of quantitative production, the first base material part 1 is divided into two parts, white base and gray base, and only the white base part and the attached antenna part are left after the gray base part passes through the cutting knife. The...

Embodiment 2

[0054] This implementation example uses a vector network analyzer to test the return loss of the fixed near-field linearly polarized antenna. The results are as follows: Figure 9 shown. The fixed near-field linearly polarized antenna can have a good reading rate for tags with a center resonant frequency near 915MHz (897MHz-936MHz); when the response frequency band of the tag frequency is greater than 925MHz, the performance of the antenna decreases rapidly and every increase of 1MHz, S11 is reduced by 0.86dB; similarly, when the frequency is less than 882MHz, for every 1MHz reduction, S11 is reduced by 0.12dB, and the antenna performance decreases rapidly. The designed antenna is used in conjunction with the design of the foldable serpentine load UHF electronic tag proposed by the present invention, which can meet the different requirements of jewelry product tags on tag performance before, during and after sales. Before sales, the real-time inventory function is required fo...

Embodiment 3

[0056] This implementation example is a fixed near-field linearly polarized antenna structure ( image 3 ,and Figure 4 ) can further derive two other specifications without changing the structure of the radiation layer, and their sizes are 48cm╳50cm and 48cm╳60cm; the combinations that can be generated from this can meet a variety of sizes. There are 6 types of counters in total, such as 48cm ╳80cm, 48cm╳90cm, 48cm╳100cm, 48cm╳110cm, 48cm╳120cm, 48cm╳130cm, 48cm╳140cm, 48cm╳150cm and 48cm╳180cm. The result of this combination meets the installation needs of most counter sizes today. The antenna structure has the same electromagnetic performance as the linearly polarized antenna structure of a single unit, and can form an array structure together with it. The specific content is the same as that of the first embodiment, and will not be repeated here.

[0057] The aforementioned linearly polarized antenna unit includes four radiating units with a complete structure. If consi...

Abstract

An intelligent counter system with a near-field linear polarization antenna array comprises anti-metal electronic tags, a micro balance, an image collection unit, a real-time checking unit, a sale safety monitoring system and an asset management database system. Each gold/jewelry article is provided with one smart-RFID dismounting-preventive tag, and the system makes information interaction for states, including stocked, to-be-sell, sold and after-sale, of each article via radio signals of the linear polarization near-field antenna unit/array, and inquires and automatic counts information of different types of articles according to information of the smart-RFID tags. The system is composed of independent control modules, and the modules execute related operations automatically and can receive control instructions from a cloud end/web server; and the system can realize distributed control for gold/jewelry assets of different counters of shops, each module has a control capability, the system flexibility is improved, and daily checking time of operators is reduced.

Description

technical field [0001] The invention relates to an intelligent counter system, in particular to an intelligent counter system for a linearly polarized near-field antenna applied in the gold and jewelry industry, which can perform online monitoring and real-time inventory functions on jewelry placed in the intelligent counter. Background technique [0002] Radio frequency identification (RFID) is a non-contact automatic identification technology realized by radio frequency technology. The RFID system is generally composed of three parts: an electronic tag (tag), a reader (reader) and a database management unit; through a coded tag and an antenna attached to the tag, the reader and the tag perform non-contact high-speed Data transfer and completion of the automatic identification process. Its working principle is that after the tag enters the magnetic field, it receives the radio frequency signal sent by the reader, and the energy obtained by the antenna structure contained i...
