As shown in fig. 1, a first embodiment of the present invention provides an RFID-based method for authenticating a carbon ribbon, which may be performed by a printer, and in particular, may be performed by one or more processors in the printer, and includes at least the following steps:
s101, acquiring a carbon ribbon recording allowance stored in an RFID label arranged on a carbon ribbon fixed structure in a verification process; wherein, the carbon ribbon recording residual amount is recorded in a first storage area of the RFID label; and the first memory area is configured to perform the operation of the value self-reduction only.
In this embodiment, the thermal transfer ribbon fixing structure may be a thermal transfer ribbon reel, a thermal transfer ribbon cassette, a thermal transfer ribbon fixing frame, or other devices that can be used to fix a thermal transfer ribbon and cooperate with a printer.
In this embodiment, an RFID tag is provided on a thermal tape fixing structure, and an independent first storage area is divided in the RFID tag for storing user-defined data. The data at least comprises the carbon tape recording allowance, and encryption or non-encryption operation can be carried out according to the needs of users.
In this embodiment, when the thermal tape is not used, the initial value of the thermal tape recording margin recorded in the first memory is the initial length of the thermal tape, and then as the thermal tape is used, the thermal tape recording margin recorded in the first memory is decreased accordingly. In particular, since the remaining amount of the carbon ribbon recorded in the first storage area cannot be increased by performing the self-subtraction operation, the RFID tag recorded with the remaining amount of the carbon ribbon can record and reflect the actual use condition of the carbon ribbon without being tampered.
In this embodiment, the RFID tag may be read by an RFID reader provided in a printer to obtain the carbon ribbon recording margin.
And S102, when the carbon ribbon recorded allowance is judged to be larger than zero, acquiring the current actual carbon ribbon allowance, and comparing the carbon ribbon recorded allowance with the actual carbon ribbon allowance to acquire a comparison difference value of the carbon ribbon recorded allowance and the actual carbon ribbon allowance.
S103, when the comparison difference is larger than a preset value, the carbon ribbon is judged to be an illegal carbon ribbon.
In this embodiment, the actual remaining amount of the carbon ribbon may be obtained by various methods, for example, typically, the actual remaining amount of the carbon ribbon may be obtained by calculating a radius of a supply roll of the carbon ribbon. Since calculating the radius of the dispensed roll of the thermal transfer printer is a mature technology at present, the invention is not described in additional detail herein.
In this embodiment, when it is detected that the carbon ribbon recording margin in the RFID tag is greater than zero, it indicates that the carbon ribbon is not used up. At this time, the recorded residual amount of the carbon ribbon is compared with the actual residual amount of the carbon ribbon acquired by the carbon ribbon sensor, so as to judge whether the current carbon ribbon is an illegal carbon ribbon or not according to the comparison result.
In particular, when the recorded allowance of the carbon ribbon is more or less than the actual allowance of the carbon ribbon, the carbon ribbon on the carbon ribbon fixed structure is possibly replaced. For example, when the thermal transfer ribbon of a genuine product is about to be used up, the value of the thermal transfer ribbon description margin stored in the RFID tag is small. If the user replaces the carbon ribbon of the genuine product with the rest carbon ribbon of the non-genuine product (the carbon ribbon fixing structure is kept unchanged), the actual residual amount of the detected carbon ribbon is the actual residual amount of the carbon ribbon of the non-genuine product (the value is usually larger), so that the actual residual amount of the carbon ribbon is far larger than the carbon ribbon recording residual amount in the RFID tag, and therefore the situation can be used for judging that the current carbon ribbon is an illegal carbon ribbon.
On the contrary, in this embodiment, when the recording margin of the thermal tape is less than or equal to zero, it indicates that the thermal tape has been exhausted in the previous printing process and is recorded in the RFID tag, and at this time, it is determined that the thermal tape is an exhausted thermal tape and is not used any more.
In summary, in the embodiment of the present invention, the carbon ribbon record residual amount stored in the RFID tag on the carbon ribbon fixing structure is compared with the actual carbon ribbon residual amount to identify the authenticity of the carbon ribbon, so as to achieve the purpose of monitoring the carbon ribbon residual amount in real time. The method ensures that each roll of the carbon tape can be legally used only once, and can prevent lawless persons from repeatedly utilizing the empty reel to use the illegal carbon tape to pretend to be a genuine product, thereby achieving the purpose of not using the carbon tape appointed by a merchant. The invention not only can maintain the benefits of merchants to a certain extent, but also can avoid the influence on the printing effect caused by the use of illegal carbon ribbons, reduce the service life of printing equipment and even cause the abnormal operation of the printing equipment.
Referring to fig. 2, on the basis of the above embodiment, in a preferred embodiment of the present invention, the RFID tag further includes a second storage area for storing a tag serial number;
then also include:
when the comparison difference is smaller than the preset value, inquiring historical carbon ribbon allowance corresponding to the label serial number in a database according to the label serial number stored in a second storage area of the RFID label;
when the historical carbon ribbon allowance is larger than the carbon ribbon recording allowance, updating the historical carbon ribbon allowance to be the carbon ribbon recording allowance;
and when the historical allowance of the carbon ribbon is smaller than the recorded allowance of the carbon ribbon, judging that the carbon ribbon is an illegal carbon ribbon.
In this embodiment, when the comparison difference is smaller than the preset value, it indicates that the recording value of the carbon ribbon recording margin is within an error allowable range, and the method can be used for further identifying the authenticity of the carbon ribbon.
In the present embodiment, the RFID tag is divided into separate second storage areas. The second storage area is internally stored with an independent tag serial number of the RFID tag, and the tag serial number is uniquely bound with the RFID tag, so that information tracing is facilitated. The tag serial number may be at least one of a tag identification number on the RFID electronic tag, an electronic product code on the RFID electronic tag, or several kinds of information in a user-defined character sequence preset on the RFID electronic tag, which is not specifically limited in the present invention.
In this embodiment, the history of the remaining amount of the thermal transfer ribbon is recorded in a database local to the printer, which is generated according to the RFID tag read by the printer. When the carbon ribbon is placed on the printer for the first time, the printer reads the tag serial number stored in the second storage area by the RFID tag and the carbon ribbon recording residual amount (the initial value is the initial length of the carbon ribbon) stored in the first storage area through the RFID reader-writer, associates and binds the tag serial number and the carbon ribbon recording residual amount, and records the tag serial number and the carbon ribbon recording residual amount in the local database. And then, when the RFID reader reads data of the RFID label every time, comparing, judging and updating the recorded residual quantity of the currently read carbon tape with the historical residual quantity of the locally and currently stored carbon tape.
Specifically, in this embodiment, when the history remaining amount of the carbon ribbon is greater than the history remaining amount of the carbon ribbon, it indicates that the carbon ribbon is consumed in the use process, and at this time, the history remaining amount of the carbon ribbon recorded in the database needs to be updated, and the history remaining amount of the carbon ribbon needs to be updated to the newly read history remaining amount of the carbon ribbon. When the carbon ribbon history residual amount is smaller than the carbon ribbon recording residual amount, the carbon ribbon history residual amount is updated later relative to the carbon ribbon recording residual amount, and the carbon ribbon recording residual amount can only be reduced or kept unchanged, so that the situation that the carbon ribbon history residual amount is smaller than the carbon ribbon recording residual amount is not possible under normal conditions, if the situation occurs, the carbon ribbon is possibly replaced, and at the moment, the carbon ribbon is judged to be an illegal carbon ribbon.
Referring to fig. 3, on the basis of the above embodiment, in a preferred embodiment of the present invention, the method further includes:
detecting whether the carbon ribbon is consumed or not at preset time intervals in the printing process;
when the consumption of the carbon ribbon is detected, acquiring the consumption of the carbon ribbon within the interval time;
updating the carbon ribbon record allowance of the first storage area and the carbon ribbon historical allowance in the database according to the carbon ribbon consumption; and
and when the carbon band recording allowance or the carbon band history allowance is detected to be less than or equal to 0, judging that the carbon band is a depleted carbon band.
In this embodiment, the carbon ribbon consumption can be obtained in various ways.
For example, a rotatable roller may be provided in the conveyance path, and the consumption amount of the carbon ribbon may be obtained by a sensor recording the number of rotations of the roller. The consumption amount of the carbon tape can also be calculated by calculating the change of the radius of the supply roll or the recovery roll of the carbon tape during the use process. Since these are existing mature technologies, the present invention is not described herein.
In this embodiment, the amount of carbon ribbon consumption of the carbon ribbon is detected every predetermined time, the remaining amount of the carbon ribbon record is updated according to the amount of the carbon ribbon consumption, and the historical remaining amount of the carbon ribbon in the database is updated according to the remaining amount of the carbon ribbon record. Therefore, the requirement of subsequent carbon ribbon authenticity identification can be met, manual interference is reduced, and labor cost is saved.
