Specific embodiment
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, will make to required in embodiment description below
Accompanying drawing is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present invention, rather than whole enforcement
Example, those skilled in the art's on the premise of not paying creative work, can also according to these accompanying drawings obtain other set
Meter scheme and accompanying drawing.
A kind of RFID guard method enabled or disabled in the passive state, methods described includes step：
1）, configuration RFID chip, the RFID chip of configuration includes aerial coil pin and I/O pin, and I/O pin includes at least one
COM pin and at least one data bit pin；COM pin can break as needed as common male end, the concrete digit of data bit pin
Solution difficulty setting, n>1, draw pin and include：
| Common port | Data bit 1 | Data bit 2 | Data bit 3 | ... | Data bit n |
| COM | D1 | D2 | D3 | ... | Dn |
Data bit is connected with common port or disconnects and can be treated as 0 or 1, or 1 or 0.COM pin can be random with multiple contacts
Connect.
As shown in figure 1, the dynamic catalyst of configuration, the contact of dynamic catalyst is pressed disorderly arranged at random, and its effect mainly has following
2 points：
（1）For fitting with quiet catalyst, play the purpose of random for quiet contacts of contactor short circuit.
（2）Under certain physical action（As the action such as torn, turning）Can be destroyed or shift, play and can not recover also
Former effect（Because cracker once trial and error chance）.
Configure quiet catalyst, quiet catalyst is used for connecting chip I/O pin and is contacted with dynamic catalyst.The IO of quiet catalyst
Wiring can be arranged in the same face it is also possible to be arranged in anyway on face with contacting contact.As shown in Fig. 2 being quiet catalyst
Contact surface, wherein black graphics be conductive contact.As shown in figure 3, being quiet catalyst pin solder side, wherein black graphics are
I/O pin pad, pin welding is random.Quiet catalyst can be together with RFID chip, antenna packages, as long as spilling contact point
?.Contact is disposed preferably with symmetrically directionless arrangement.
The RFID chip of configuration also includes a reading and writing data posting field, reads the number of input I/O pin for record
According to.Externally communication is invisible for this data, only allows internally to use.
2）, after dynamic catalyst fixed with quiet catalyst, Producer sends initialization command, and RFID chip receives
After this order, read current data and write reading and writing data posting field, before any order of RFID chip response, read first
Chip I/O data is contrasted with the data of described reading and writing data posting field, and contrast is consistent just to be responded, and is otherwise not responding to, and
RFID chip is locked.
A kind of RFID protection system enabled or disabled in the passive state, including RFID chip, dynamic catalyst with quiet connect
Tentaculum, RFID chip includes aerial coil pin and I/O pin, and I/O pin includes at least one COM pin and at least one data
Position pin；RFID chip also includes a reading and writing data posting field, reads the data of input I/O pin for record；Move and connect
The contact of tentaculum is disorderly arranged at random, for fitting with quiet catalyst, by random for quiet contacts of contactor short circuit, and in certain thing
Can be destroyed under reason effect or shift it is impossible to recover to reduce；Quiet catalyst, for connecting chip I/O pin and connecing with dynamic catalyst
Touch.Data bit pin in I/O pin connects with COM pin respectively or disconnects, and data bit pin corresponding output logic is：0 or
1, or：1 or 0, the IO wiring of quiet catalyst can be arranged in the same face it is also possible to be arranged in anyway with contacting contact
On face, COM pin is connected at random with one or more contacts.
Specifically, the inventive method is described further so that famous brand of wine is false proof for specific embodiment.
（1）RFID chip, coil, quiet catalyst are packaged together formation rfid card.
（2）Rfid card is fixed on the correct position of wine bottle cover, and contacts with the random site on moving contacting plate（Institute
To be suitable for random site, it is to make the data on each commodity different）, dynamic catalyst can be attached to the glass of bottle mouth
On, area can be more than quiet catalyst area.
（3）Send initialization command before dispatching from the factory, allow RFID store the data of current I O read.
（4）Using reader-writer to read RFID information before bottle cap is not turned on, because dynamic catalyst is relative with quiet catalyst
Position is unchanged, no damage, and the data message of I O read is consistent with being stored in data message in memorizer, and RFID function is normal.
（5）After bottle cap is opened, because physical action leads to dynamic catalyst to destroy or to move catalyst relative with quiet catalyst
Position changes, and is stored in data message inconsistent, the RFID chip deadlock of appearance in the data message of I O read and memorizer.
It should be noted that the above is presently preferred embodiments of the present invention, the invention is not limited in above-mentioned
Embodiment, as long as it reaches the technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
