Description

An Embedded RFID Tag Identification Technology

technical field

The invention belongs to the technical field of embedded identification, and in particular relates to a pearl core embedded with an RFID tag and a method for identifying the authenticity of the pearl.

Background technique

Since ancient times, natural pearls have been a precious and rare gift from nature to human beings. They are formed when some foreign matter such as sand, parasites or their remains enters the soft shell of mussels, which in turn causes mussels to instinctively resist foreign invasion. . Under natural circumstances, it is extremely difficult to produce a good pearl under the influence of various factors. With the current maturity of pearl breeding technology, most pearl ornaments on the market are artificially cultured. Cultured pearls are mainly divided into two categories: nuclear pearls and non-nuclear pearls. Among them, most of the pearl cores of nuclear pearls are made of mussel shells, gravel, stones, etc.

Generally speaking, it takes 0.5-2 years for an artificial pearl to grow from the birth of the mother to the final pearl. For different culture techniques, culture environments, and selection of different mussels, the quality of pearls will vary greatly in terms of color, luster, shape, smoothness, etc., and it is difficult for people to identify their quality grades. What makes people sad is that those who seek profit and counterfeit even use various means to manufacture a large number of artificial pearls, posing fakes as real, shoddy as good, and defrauding consumers of their legitimate rights and interests. In order to solve the problem that it is difficult for people to identify the quality grade and authenticity of pearls, the RFID tag chip cured with epoxy resin binder is used instead of foreign matter such as sand, parasites, and remains as pearl cores, and is combined with common core insertion technology and follow-up Advanced post-operative recuperation and bead breeding technology will eventually form nucleated pearls with embedded RFID tags, so as to achieve efficient and accurate identification of pearl quality, performance and authenticity. At the same time, writing certain information to the RFID tag before inserting the core technology is also conducive to the management and tracking of the entire growth process of the pearl.

Contents of the invention

The object of the present invention is to provide a pearl core embedded with RFID tags.

The object of the present invention is also to provide a quick and accurate method for identifying the quality and authenticity of pearls.

A kind of pearl core with embedded RFID tag, it is characterized in that, described pearl core is made of RFID tag 1, antenna 2, epoxy resin 3, shell powder 8; Antenna 2 is attached on the RFID tag chip 1; RFID tag chip 1 The outer layer of the composite with the antenna 2 is covered with epoxy resin 3; the outer layer of the epoxy resin 3 is covered with shell powder 8.

The RFID tag 1 is an active RFID tag, a semi-active RFID tag or a passive RFID tag.

The RFID tag is used to store the species of mussels selected during bead breeding, bead breeding place, time of inserting nuclei, recuperation time after operation, harvest time, and living environment.

The RFID tag has a built-in non-erasable program.

The antenna 2 is an integrated antenna or an independent antenna.

A method for identifying the authenticity of pearls with an embedded RFID tag, which is characterized in that a certain amount of energy and signals are sent through the card reader 4, and the RFID tag embedded in the pearl 5 returns its information to the card reader 4 to achieve high efficiency. Accurately identify the efficacy of Pearl 5 information.

The pearl 5 breeding method is as follows: insert the pearl nucleus embedded with RFID tags and the cell pieces removed from the sliced mussel into the connective tissue between the inner and outer skin of the sliced mussel, and then treat the mussel wound with lecithin solution or Tetracycline drug treatment, and finally after 0.5-2 years of natural cultivation.

Beneficial effects of the present invention: the present invention sends certain energy and signals to the RFID tag embedded inside the pearl through the card reader, and the RFID tag receives the energy and converts it into the power supply voltage required for its own work without the need for an external battery At the same time, it interprets the signal sent by the card reader through its own internal radio frequency analog circuit and digital analog circuit, and returns the corresponding information at the same time, so that people can quickly and conveniently get relevant information about pearls. The information stored in the RFID tag of the present invention cannot be erased, and the information can be rewritten during and after the pearl cultivation, which further strengthens the identification and management of pearls.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Example 1

In this embodiment, the pearl core embedded with RFID tags is composed of RFID tags 1, antenna 2, epoxy resin 3, and shell powder 8. The antenna 2 is attached to the RFID tag chip 1, and the composite outer layer of the RFID tag chip 1 and the antenna 2 Epoxy resin 3 is coated, and the outer layer of epoxy resin 3 is coated with shell powder 8 (Fig. 1-2).

Cultivate pearls 5 from pearl nuclei embedded with RFID tags (Fig. 3). The breeding method is: write relevant identification information (information cannot be deleted) into the RFID tag chip 1 in advance according to customer requirements, including the type of mussel selected, the place where the pearls are raised , insertion time, postoperative rest time, harvest time, and living environment; insert the pearl nucleus with embedded RFID tags and the cell pieces removed from the sliced mussel into the connective tissue between the inner and outer skin of the sliced mussel, and then Treat the mussel wound with lecithin solution or tetracycline, and the epidermal cell tissue of the mantle of the mussel will surround the pearl nucleus made of the RFID chip cured with epoxy resin-based cement, forming a complete pearl sac, and centering on it. Gradually secrete nacre layer by layer, and form pearls after 0.5-2 years of natural cultivation; at any stage of pearl cultivation, relevant information can be written according to customer requirements (information cannot be deleted).
