Abstract

The utility model discloses an electronic seal, comprising a seal part, and an antenna and an RFID chip arranged in the interior of the seal part. The RFID chip matches the antenna, and is in wireless connection with a reader-writer via the antenna. In the utility model, by embedding the antenna and the RFID chip in the conventional electronic seal, the functions, such as identification, confirmation, anti-counterfeiting, etc., carried out on the sealed articles are realized; moreover, by adding the RFID chip supporting the reading and writing operations in the conventional electronic seal, the information of sealed articles can be recorded, such as under-seal time, detection time, article name or list, transportation information, tracing information, etc., and the real-time tracking or traceability function carried out on the sealed articles or operators can be realized via internet of things or an internet, thereby satisfying the use demands of people.

Description

A kind of electronic seal

Technical field

The utility model relates to the electronic seal technical field, relates in particular to a kind of electronic seal of the RFID of being provided with chip.

Background technology

In present seal field, most popular is lead sealing, promptly utilizes special-purpose pressing tongs that sealing lead is flattened, thereby realizes the container in measurement instrument such as water, electricity and gas three tables, taximeter or the carrier or the seal of concerning security matters safe deposit box.But existing lead sealing or being similar to other seals such as plastics seal of lead sealing is because they are mass customized, so can not accomplish through seal the envelope article to be identified logistic track, false proof and seal etc. one to one.

Therefore, electronic seal has produced with regard to the user demand of complying with people, but traditional electronic seal still can not satisfy above-mentioned seal requirement.

And the RFID technology is at present in every profession and trade widespread use and development, use the RFID technology can realize data storage, false proof, follow the tracks of, and rely on Internet of Things or internet realize to article real-time follow-up, review etc.But remain blank out to the RFID technical application to the electronic seal technical field.

So, to the electronic seal field, realize the RFID technical application envelope article are identified, confirm, false proof, will become the trend of the times of electronic seal development.

The utility model content

In order to solve the problem that above-mentioned prior art exists, the purpose of the utility model be to provide a kind of with the RFID chip application in electronic seal, can utilize this RFID chip to realize the envelope article are identified, affirmation, the electronic seal of function such as false proof.

To achieve these goals, the technical scheme content of the utility model employing is specific as follows:

A kind of electronic seal comprises the seal part, at the seal partial interior antenna and RFID chip is housed; Said RFID chip and said antenna are complementary, and connect a read write line through said antenna wireless.

Wherein, preferably, said seal partly is a strapping.

Or said seal partly comprises seal housing and seal lid; Said RFID chip and antenna are installed between the bottom surface and seal lid of seal housing.In addition, said seal part also comprises a flexible seal line.

Preferably, said antenna is a tours antenna.

Preferably, said antenna is an etching antenna or printed antenna.

Preferably, said RFID chip is read-only or the RFID chip of support read-write operation.

Preferably, said RFID chip read-only or the support read-write operation is low frequency RF ID chip or high-frequency RF ID chip or ultrahigh frequency RFID chip.

Wherein, need to prove that low frequency RF ID chip is meant the RFID chip of read-write frequency at the read-only of 30-300KHz or support read-write operation, it is the read-only of 125KHz or the RFID chip of supporting read-write operation that the utility model preferably adopts the read-write frequency; High-frequency RF ID chip is meant the RFID chip of read-write frequency at the read-only of 3-30MHz or support read-write operation; The ultrahigh frequency RFID chip is meant the RFID chip of read-write frequency at the read-only of 300-3000MHz or support read-write operation.

Preferably, said high-frequency RF ID chip employing is produced by NXP company, meets the high-frequency RF ID chip of ISO14443 or ISO15693 standard.

Preferably, said ultrahigh frequency RFID chip employing is produced by NXP company, meets the ultrahigh frequency RFID chip of ISO18000 standard.

The electronic seal of the utility model can carry out read-only or read-write operation to electronic seal through the read write line of special use after RFID chip and antenna are implanted the seal part.Concrete principle of work is: RFID chip and antenna have been confirmed a read-write frequency; And read write line also is operated on this frequency, and read write line and RFID chip have just formed radio frequency coupler like this, after read write line just can read self id number of RFID chip; Its id number is corresponding with sealing up for safekeeping article; Functions such as realization is to the sign of envelope article, confirms, and is false proof.

Need to prove, when the electronic seal of the utility model is implanted the read-only RFID chip, after the read-only RFID chip writes down the id number of himself, that its id number is corresponding with sealing up for safekeeping article.

Also need to prove; When the electronic seal of the utility model is implanted the RFID chip of supporting read-write operation; Support the RFID chip of read-write operation not only can realize read-only RFID chip identical functions; But also can following envelope time of envelope article, place, product information etc. be write in its inside; Also can be regularly checking information (for example, the supervision time), transit information and the trace information etc. of envelope article be write in its inside, to realize that sealed article such as are reviewed at function; And; The RFID chip of this support read-write operation can also use read write line that it is carried out read-write operation or uses read write line that it is carried out read-write operation in different places through the different operation personnel through the different operation personnel in same place; Realization is to the operating personnel of envelope article or the function of operatively reviewing; Simultaneously, the RFID chip of this support read-write operation can also be realized the control of logistics and operating personnel's control through Internet of Things or internet.

Compared with prior art, the utility model has produced following beneficial effect:

The utility model is through implanting antenna and RFID chip in traditional electronic seal; Realization identifies the envelope article; Confirm, function such as false proof, and; When in traditional electronic seal, adding the RFID chip of supporting read-write operation; Can also write down the information such as following envelope time, supervision time, Item Title or inventory, transit information, trace information of the article that seal, and can rely on Internet of Things or internet to realize or review function, satisfy people's user demand envelope article or operating personnel's real-time follow-up.

Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
