Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. indicate an orientation or a positional relationship based on that shown in the drawings or that the product of the present invention is used as it is, this is only for convenience of description and simplification of the description, and it does not indicate or imply that the device or the element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
Furthermore, the appearances of the terms "first," "second," and the like, if any, are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a view of an application scenario of the chip verification method according to the embodiment of the present invention, where the chip verification method includes an imaging device 10, each imaging box of the imaging device 10 is provided with a chip 20-1, and the chip 20-1 may communicate with the imaging device through a network. Wherein, the chip 20-1 also has chips 20-2,20-2,20-3, …, 20-n with the same serial number.
The imaging device 10 may maintain and count serial numbers of chips that are historically installed on the computer, and may verify the chips that are currently installed on the computer. For example, the chip is usually verified to store information such as the model number, serial number, consumable capacity, consumable consumption, number of prints, and number of prints of the consumable container.
For example, assuming that the chips 20-2 through 20-n are all historically operated chips, the imaging device 10 remembers the serial number of any one of the chips 20-2 through 20-n after the chip is first used by the imaging device 10. When the chip 20-1 is mounted, the imaging device 10 obtains the serial number of the chip 20-1 and verifies whether the serial number of the chip 20-1 is overlapped with the counted serial number.
It is understood that the above-mentioned verification function may be implemented by other devices, for example, the chip 20-1 sends the verification information to the device with data analysis function for verification, and then sends the verification result to the imaging device 10.
It is noted that the image forming apparatus may be, but is not limited to, a copying machine, a printer, a facsimile machine, a word processor, and the like.
Referring to fig. 2, fig. 2 is a schematic view of an electronic device according to an embodiment of the present invention, and the electronic device may be respectively connected to the chip 20-1 and the imaging device 10 shown in fig. 1 in a communication manner. The electronic device 20 includes a memory 210, a communication interface 220, and a processor 230;
the memory 210, communication interface 220, and processor 230 components are electrically connected to each other, directly or indirectly, to enable the transfer or interaction of data. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The chip verification apparatus 500 includes at least one software function module that may be stored in the memory 210 in the form of software or firmware (firmware) or solidified in an Operating System (OS) of the electronic device. The processor 230 is used to execute executable modules stored in the memory 210, such as software functional modules or computer programs included in the chip verification apparatus 400.
The Memory 210 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like. The memory 210 is used for storing a program, the processor 230 executes the program after receiving an execution instruction, and the method for executing disclosed in any embodiment of the present invention may be applied to the processor 230, or implemented by the processor 230.
Further, with continued reference to fig. 1, taking a printer as an example, in the prior art, each imaging cartridge of the printer is provided with a consumable chip, when the chip is used by the printer for the first time, the printer remembers the serial number, when the powder box or the ink box corresponding to the chip is used completely, the printer marks that the chip corresponding to the serial number is used completely, even if the data of the chip is reset by using a reset technology, or the chip with the same serial number is installed on a powder box or an ink box still having carbon powder or ink and then is installed on the printer again through the ink box or the powder box, the printer still considers that the powder box or the ink box installed with the chip is used, thereby preventing the use of the compact or cartridge, resulting in the inability to reuse the compact or cartridge and the chip.
The related art also provides a serial number adjustment scheme to solve the above problems, but the serial number of the chip that can be recognized by the imaging device is limited, and thus the above problems cannot be completely solved, and therefore, based on the above situation, there is a need for a method for a chip that can be recognized by a printer without changing the serial number, so that the chip with the repeated serial number can be used in the same printer, and further, the chip of the cartridge or the ink cartridge can be reused by the printer even if the chip of the cartridge or the ink cartridge has the same serial number.
Based on the above problem, in order to enable a chip with a repeated serial number to be used in the same printer and also enable the chip of a powder box or an ink box to be reused by the printer even if the chip has the same serial number, the printer is still taken as an example below to describe a chip provided by the embodiment of the present invention.
In the chip provided in the embodiment of the present invention, a check field and a sequence number generated in advance are simultaneously burned into the chip in a chip manufacturing process, where the check field may be as shown in fig. 3, and fig. 3 is an exemplary diagram of a check field maintenance table of the chip provided in the embodiment of the present invention, where data "1316073863" in a black frame corresponds to the check field of the chip and has an address of 0x13-0x17, which is 5 bytes of data. The check field can be generated on a burning frame, then is filled to the corresponding position of the black frame, and then is burnt into the chip.
It should be noted that the check fields in each chip are not all FF or 00, and the 5-byte check fields can be regarded as infinite.
Further, the printer records the serial number and the unit check field to determine whether the serial number is used repeatedly by the printer, and if the check field is determined to be different, the printer still considers that the serial number is used first by the printer. As long as the check fields in each chip are different, the chips which are considered by the printer that the sequence numbers are not repeated can be obtained under the condition of limited sequence numbers.
In one example, the check field provided by the embodiment of the present invention may be generated by:
Wherein, the sequence number of each target chip is the same.
And 2, aiming at the first target chip, constructing initial random data as the check field of the first target chip.
Wherein, the first target chip is any one of all target chips.
And 3, aiming at the current target chip, generating the check field of the current target chip according to the check field of the last upgraded target chip and the upgrade code of the current target chip.
Wherein the current target chip is any one of the remaining target chips except the first target chip.
And 4, traversing all the remaining target chips until the check field of each target chip is obtained.
It should be noted that the upgrade code may be a count value of a timer, for example, please refer to fig. 1 again, assuming that the target chips are chips 20-1 to 20-n, when the chip 20-1 is manufactured, the timer is started to count, the count value is 1, when the chip 20-2 is manufactured, the count value is 2, and so on, the count value of the chip 20-n is n.
Continuing with the example of chips 20-1 through 20-n in fig. 1, the above process can be understood as follows: the upgrade codes corresponding to the chips 20-1 to 20-n are 1 to n, respectively. Assuming that the chip 20-1 is the first target chip, a check field is randomly generated as the chip 20-1, then, for the chip 20-2, the check field of the chip 20-2 is generated according to the check field of the chip 20-1 and the upgrade code of the chip 20-2, the check field of the chip 20-3 is generated according to the check field of the chip 20-2 and the upgrade code of the chip 20-3, and so on, and the check fields of the chips 20-1 to 20-n are obtained.
In one example, a preset compression algorithm may be used to generate a new check field according to the check field and the upgrade code, so that the input value of the compression algorithm is always changed, and therefore, the sequence number is repeated in time, and the obtained chip check fields are also different and can be verified by the same printer.
The chip provided by the embodiment of the invention can provide the sequence number and the preset check field of the chip; presetting a check field for distinguishing different chips with the same sequence number; the sequence number and the preset check field are used for: when the serial number is judged to be correct and the preset check field is not consistent with the historical check field in the historical record, the chip to be verified is determined to pass verification, wherein the historical chip communicated with the imaging equipment corresponds to the historical check field, so that the chip can pass verification under a certain condition even if the chip has the same serial number, the repeated use is realized, and the equipment cost is saved.
Based on the obtained chip, a method for verifying the chip is provided below, please refer to fig. 4, where fig. 4 is a schematic flowchart of a method for verifying the chip according to an embodiment of the present invention, the method for verifying the chip can be applied to the imaging device shown in fig. 1 or the electronic device shown in fig. 2, and the method includes:
s401, acquiring a sequence number and a preset check field corresponding to a chip to be verified.
The chip to be verified is installed on the imaging equipment, and the check field is preset and used for distinguishing different chips with the same sequence number.
S402, when the serial number is judged to be correct and the preset check field is not consistent with the historical check field in the historical record, determining that the chip to be verified passes the verification.
Wherein the history chip and the history check field in communication with the imaging device correspond. The history chip is a chip which is historically installed on the imaging device, and when the history chip is used by the imaging device for the first time, the imaging device can acquire the serial number and the check field of the history chip.
In the implementation process, whether the serial number is correct or not can be judged firstly, if the serial number is incorrect, the chip is directly determined to fail the verification, if the serial number is correct, whether the verification field is consistent with the historical verification field or not is continuously judged, if the verification field is not consistent with the historical verification field, the verification is passed, and if the verification field is consistent with the historical verification field, the verification is failed.
It should be noted that there is no execution sequence for determining whether the sequence number is correct and determining whether the check field is consistent with the history check field, and the sequence number may be verified before the sequence number is verified, or the sequence number may be verified before the check field is verified, which is not limited herein.
In a possible embodiment, the history record may be maintained by the imaging device, or may be maintained by other devices having an analysis function, and when maintained by other devices, the other devices may receive all the sequence numbers and check fields recognized by the imaging device, so as to generate the history record.
For convenience of understanding, please continue to refer to fig. 1, assuming that the chip to be verified is the chip 20-1, the chips 20-2 to 20-n are historical chips communicating with the imaging device, that is, chips that have been used on the imaging device, the imaging device records the sequence numbers and check fields of the chips 20-2 to 20-n, the chip 20-1 is the same as the sequence numbers of the chips 20-2 to 20-n, but the check fields are different from these chips, and therefore, in the case that it is determined that the check field of the chip 20-1 is not consistent with the check fields recorded on the imaging device, it may be determined that the chip 20-1 passes verification.
The chip verification method provided by the embodiment of the invention is different from the prior art in that the prior art only determines whether the chip is repeatedly used through the serial number, so that the chip with the same serial number and the imaging box corresponding to the serial number cannot be continuously used, other chips need to be replaced, and the waste of equipment cost is caused; the chip to be verified is arranged on the imaging equipment, and a verification field is preset and used for distinguishing different chips with the same sequence number; and when the serial number is judged to be correct and the preset check field is not consistent with the history check field in the history record, determining that the chip to be verified passes the verification, wherein the history chip communicated with the imaging equipment corresponds to the history check field. Therefore, even if a certain serial number repeatedly appears in the same imaging device, the serial number can still be mistaken as the first-time used serial number by the imaging device due to different check fields, so that the chip with the repeated serial number can be used in the same imaging device, and the effect that the powder box or the chip of the ink box can be repeatedly used even if the chip of the powder box or the ink box has the same serial number can also be realized.
It should be noted that the chip verification method provided in the foregoing embodiment is applicable to a scenario where chips with the same serial number are used in the same imaging device, and if the chips with the same serial number are used in different imaging devices for the first time, the above problem may not occur.
It should be further noted that, when the chip verification method is applied to the imaging device 10 shown in fig. 1, the imaging device 10 obtains the serial number and the preset check field of the chip to be verified and then executes the verification function, and when the chip verification method is applied to the electronic device shown in fig. 2, after the electronic device receives the successful chip installation, the electronic device may obtain the serial number and the preset check field sent by the chip, execute the verification function, and then send the verification result to the imaging device, or after the electronic device receives the successful chip installation, the electronic device may obtain the serial number and the preset check field obtained from the chip by the imaging device, and then execute the verification function, and send the verification result to the imaging device, which is not specifically limited herein.
Alternatively, when the chip passes the verification, the imaging device may be controlled to perform imaging operations, for example, printing, copying, faxing, etc. operations may be performed. And when the chip to be verified is determined not to pass the verification, controlling the imaging equipment to output prompt information of verification error.
Continuing with the example of a printer, the printer may record the historical verification field of the historical chip, if the chip corresponding to the verification field SN1 is replaced with a new cartridge after the printer has finished a life (the chip becomes empty from a new one with stored consumable (toner or ink) capacity), and if the serial number of the chip in the cartridge is also SN1 and the verification field is consistent with the verification field recorded by the printer last time, the machine will report an error. Therefore, even if there are several chips having the SN1 serial number, the check fields in each SN1 chip are different, and thus several chips repeating the SN1 can be used normally when they are used in the same printer.
Optionally, in order to prolong the service life of the chip, a possible implementation is further provided below, please refer to fig. 5, where fig. 5 is a schematic flowchart of another chip verification method provided in an embodiment of the present invention, and the method may further include:
and S403, acquiring the consumable capacity of the chip to be verified.
In order to ensure the smooth proceeding of the subsequent imaging operation, the information of the consumable capacity of the chip, the consumption of the consumable, the printing times, the printing quantity and the like can be verified. When the chip passes the verification, the consumable capacity can be obtained.
S407, if the consumable capacity is determined to reach the preset value, modifying the preset check field to obtain the updated preset check field.
And S408, resetting the consumable volume to the initial maximum consumable volume.
It can be understood that if it is determined that the consumable capacity reaches the preset value, it indicates that the consumption of the capacity of the chip is almost zero, the chip cannot be used continuously, the imaging device marks that the chip corresponding to the check field cannot be used continuously, and in order to prolong the service life of the chip, the check field of the chip can be modified.
In an example, the manner of modifying the check field may be the same as the manner of generating the check field in the foregoing, and is not described herein again.
Optionally, although the foregoing embodiment may extend the service life of the chip, in order to avoid that the chip is used without limitation, which causes confusion in the market and severe abrasion in chip use, an implementation manner is further provided below, please refer to fig. 6, where fig. 6 is a schematic flowchart of another chip verification method provided in the embodiment of the present invention, and the method may further include:
s404, judging whether the modification times corresponding to the chip to be verified reach the preset times or not.
S405, if the number of times of modification reaches the preset number of times, controlling the imaging equipment to output prompt information of chip replacement. If the number of times of modification does not reach the preset number of times, step S407 is executed.
Through the implementation process, the modification times of the chip can be controlled, and the problems of market disorder and serious abrasion of the chip due to unlimited modification and use of the chip can be avoided.
Optionally, an implementation manner of obtaining the sequence number and the check field is further provided below, please refer to fig. 7, fig. 7 is a schematic flowchart of another chip verification method provided in the embodiment of the present invention, where step S401 may include:
s401-1, a sequence number maintenance table of a chip to be verified and at least one check field table are obtained.
S401-2, according to the preset secret key, the sequence number is analyzed from the sequence number maintenance table, and the preset check field is analyzed from the check field table.
In this embodiment, the chip to be verified may obtain other data tables of the chip to be verified, which are used for verifying other attribute information of the chip to be verified, for example, information such as a model, a serial number, a consumable capacity, a consumable consumption amount, a printing number, and a printing quantity of a consumable container is usually stored in the chip.
In order to ensure the security of the data information provided by the chip, the serial number maintenance table is bound with a group of secret keys, so that the serial number of the chip to be verified can be obtained by analyzing according to the secret keys after the serial number maintenance table is obtained.
In one embodiment, if a plurality of check field tables exist, when the sequence number is judged to be correct and a preset check field in one check field table is inconsistent with a historical check field in a historical record, determining that the chip to be verified passes the verification; or if a plurality of check field tables exist, when the sequence number is judged to be correct and the preset check fields corresponding to all the check field tables are inconsistent with the historical check fields in the historical record, determining that the chip to be verified passes the verification.
