Embodiment one
In order to solve the above-mentioned problems in the prior art, the embodiment of the present invention provides a kind of sequence number transmission method.
This method can be implemented in the consumable chip in imaging cartridge.
Specifically, imaging cartridge involved in the embodiment of the present invention can include but is not limited to：Print cartridge；It is placed in imaging cartridge
Image forming medium can include but is not limited to：Ink.
Specifically, please refer to Fig.1, the stream of the embodiment one of the sequence number transmission method provided by the embodiment of the present invention
Journey schematic diagram, as shown in Figure 1, this method comprises the following steps：
S101 when consumable chip, which receives printer, provides electric energy, is generated according to specific mode and is stored sequence number.
Specifically, when imaging cartridge is installed in printer, printer can be with for the consumable chip progress in imaging cartridge
Power supply, at this point, consumable chip powers on.
In the embodiment of the present invention, consumable chip can according to default specific mode formation sequence number, wherein, specific mode
To indicate using which kind of algorithm formation sequence number, also indicating the form of the sequence number of generation and number etc..
If for example, pre-set the form of sequence number in consumable chip as XYXYXY, wherein, X represents letter, Y generations
Table number then when consumable chip receives printer and provides electric energy, just generates a sequence according to preset format XYXYXY
Number.
It should be noted that after consumable chip receives printer offer electric energy, can be given birth to according to default specific mode
Into a sequence number, alternatively, generating multiple sequence numbers.
It should be noted that in the embodiment of the present invention, consumable chip is raw after the electric energy of printer offer is received every time
Into sequence number be all different.In this way, even if this during this recognizes machine, is returned to the sequence of printer by printer
It number is marked, when imaging cartridge is when being installed to printer next time, consumable chip finally can be with by printer's marks mistake
Sequence number realize identification certification of the printer to sequence number, in this way, the use that this imaging cartridge just can be repeatedly.
In actual application, consumable chip can generate a sequence number at random according to specific mode, alternatively, also may be used
With according to default algorithm formation sequence number.
If for example, Serial No. 00001 that consumable chip is generated according to above-mentioned specific mode, it is assumed that default algorithm is every
It is secondary to increase by 1 on the basis of the sequence number of last time generation, then when consumable chip receives the electric energy of printer offer next time,
The sequence number generated according to specific mode is exactly 00002；When consumable chip third time receives the electric energy of printer offer, press
According to specific mode generation Serial No. 00003, and so on, repeat no more.
In order to which this programme is better described, the embodiment of the present invention provides a kind of specific implementation of formation sequence number：
The factor that can change with the time of sequence number generation is included in the sequence number of consumable chip generation.
It should be noted that the factor included in sequence number can include following both sides content：
In a first aspect, temporal information during consumable chip formation sequence.
Specifically, the temporal information carried in this factor can be：At the time of during consumable chip formation sequence.Or
Person, the temporal information carried in this factor can also be：Data processing is carried out at the time of during to consumable chip formation sequence
The regular character combination obtained afterwards.
Second aspect, the character combination that when consumable chip formation sequence generates at random.
Specifically, the character combination generated at random includes：Generate at random number combination and/or, the letter generated at random
Combination, the embodiment of the present invention is to this without being particularly limited to.It should be noted that the character group that consumable chip generates at random every time
It is all different from the character combination that the last time generates at random to close.
It should be noted that during actually realizing, the factor that is included in sequence number can only include above-mentioned two aspect
One side in content, alternatively, this factor can also include two above-mentioned aspect contents simultaneously.
It should also be noted that, in the embodiment of the present invention, the sequence number of consumable chip generation include it is above-mentioned can be with sequence
Time of row number generation and the factor that changes, still, to the length of position of this factor in sequence number or character string not into
Row is particularly limited to.
For example, when consumable chip starts to receive the electric energy of printer offer, one group or more can be generated according to specified format
The sequence number of 8 bytes of group, and the factor changed with sequence number generated time included in sequence number, can be located at every group 8
Preceding several bytes of a byte or rear several bytes positioned at every group of 8 bytes, alternatively, 8 in the sequence number of every group of 8 bytes
A byte is generated according to this factor.
Specifically, according to preceding 4 bytes in assuming the sequence numbers of every group of 8 bytes this with sequence number generated time and
The factor generation of variation.At this time, this 4 bytes can all be temporal information when consumable chip generates this sequence number,
For example, 1220, this 4 bytes show that consumable chip is mitogenetic into this sequence number 12: 20.
Alternatively, this 4 bytes can all be the character combination that consumable chip generates at random when generating this sequence number, example
Such as, A1B1, this 4 bytes are that consumable chip generates at random in formation sequence.
Alternatively, this 4 bytes can also include the temporal information and character when consumable chip generate this sequence number simultaneously
Combination, for example, 12B1, the first two byte in this 4 bytes is to carrying out handling at the time of consumable chip formation sequence
The number combination arrived, the character combination that latter two byte is randomly generated.
Specifically, all include what this changed with the generated time of sequence number in the consumable chip of consumable chip generation
The factor, then, for consumable chip in each formation sequence, this sequence number is all when generating current sequence number with consumable chip
At the time of it is related, formation sequence each due to consumable chip at the time of is all different, so, consumable chip is every secondary
Into sequence number in the factor that includes and the factor included during last formation sequence it is different, thus, ensure that consumable chip
The sequence number generated every time is all different.
Specifically, in the embodiment of the present invention, after consumable chip formation sequence number, it is also necessary to deposit the sequence number of generation
Storage.
During a concrete implementation, the sequence number of generation can be stored in data buffer zone.
Specifically, exist to carry out the data buffer area of information exchange, depositing in data buffer area with printer in chip
The data of storage can be purged under certain condition, can't be stored for a long time.Therefore, chip formation sequence number is stored in data
Then the sequence number that data buffer area stores is returned to printer by buffer area.
It specifically, during another concrete implementation, can also preset when consumable chip powers off, erasing data are delayed
Deposit the sequence number of area's storage.For example, when imaging cartridge departs from printer, electricity under the chip in imaging cartridge, it is possible to wipe data
The sequence number of buffer area storage.
It is understood that when the number of the sequence number of chip generation is at least two, the sequence of storage can also be preset
The form of row number.For example, multiple sequence numbers of generation can be stored in data buffer zone in a tabular form.
Specifically, data buffer zone can be static RAM (Static Random Access
Memory, SRAM).SRAM is not required refresh circuit that can preserve the data of storage inside, and therefore, SRAM has higher property
Can, power consumption is smaller, can promote whole work efficiency.
In actual application, consumable chip can also be generated and stored when receiving the electric energy of printer offer
The key information related with sequence number facilitates the use the authentication that this key information realizes material chip and printer.
Specifically, consumable chip while each formation sequence, also generates secret with this sequence number relevant first
Key information, and the first key information is stored.In this way, after this sequence number is sent to printer by consumable chip, beat
Print machine also can generate second key information according to this sequence number.Then, in the communication into line printer and consumable chip
In verification process, consumable chip can be believed after the authentication instruction of printer transmission is received according to this first secret key
Breath the first check value of generation, then returns to consumable chip, at this point, consumable chip is secret also according to second by this first check value
Key information generate the second check value, then, printer can by judging whether the first check value consistent with the second check value,
To verify whether printer and consumable chip communicate success.
Stored sequence number when receiving the designated order of printer, is returned to printer by S102.
Specifically, designated order instructs for authentication.
Specifically, when trigger printer to imaging cartridge carry out authentication when, printer send authentication instruct into
As the consumable chip in box, and the consumable chip in imaging cartridge is after authentication instruction is received, it is necessary to printer
A sequence number is returned to, to complete identification certification of the printer to imaging cartridge.The sequence that only printer returns to consumable chip
Number identification certification authentication to imaging cartridge is completed by, printer, can just use image forming medium in imaging cartridge into
The work such as row printing.
The embodiment of the present invention carries out imaging cartridge for triggering printer the condition of authentication without being particularly limited to,
In practical application, it can be preset according to actual needs.For example, can preset when imaging cartridge is installed in printer, touch
It sends out printer and authentication is carried out to imaging cartridge；Alternatively, in another example, it can preset when the cover closure of printer, triggering is beaten
Print machine carries out authentication to imaging cartridge；Alternatively, in another example, it can preset when printer is started shooting, triggering printer is to imaging
Box carries out authentication；Alternatively, in another example, it can preset when printer is powered for imaging cartridge, triggering printer is to imaging cartridge
Carry out authentication.
In the embodiment of the present invention, after consumable chip receives the authentication request of printer, the sequence number of storage is returned
Back to printer.
As soon as if specifically, consumable chip generates and stores a sequence number, this sequence number stored is returned to and is beaten
Print machine.If consumable chip generates and stores multiple sequence numbers, after the authentication request of printer transmission is received, depositing
One sequence number of selection returns to printer in multiple sequence numbers of storage.
In this way, since the sequence number of consumable chip generation is all different, so, consumable chip returns to the sequence of printer
Row number is also different, finally, can be found in consumable chip generation, the sequence number that stores and return to printer one not by
The sequence number that printer's marks are crossed, it is thus possible to the sequence number do not crossed by this by printer's marks complete printer into
As the identification verification of box, and then, it can realize repeatedly using for imaging cartridge, avoid imaging cartridge in the prior art and only use
Once just problem of resource waste and problem of environmental pollution caused by discarded.
Specifically, in the embodiment of the present invention, when consumable chip powers off, stored sequence number is wiped.So work as consumptive material
Chip obtains the electric energy of printer offer next time when, this sequence number for returning to printer is not stored in consumable chip,
Also, since the sequence number that consumable chip generates every time is all different, it further ensure that this will not be returned to and beat
The sequence number of print machine again returns to happening to printer, so as to ensure that the recycling rate of waterused of imaging cartridge.
The technical solution of the embodiment of the present invention has the advantages that：
In the embodiment of the present invention, when chip receives the electric energy of printer offer, generate and store according to specific mode
Then stored sequence number, when receiving the designated order of printer, is returned to printer by sequence number.It is of the invention real
It applies in example, when printer is the chip power supply in imaging cartridge, what the consumable chip in imaging cartridge can be needed according to printer
Form or requirement one sequence number of generation, this way it is not necessary to prestore excessive sequence number in consumable chip, also would not
The excessive memory space for occupying consumable chip, and then, it is possible to reduce the increase and waste of Material Cost；On the other hand, it is of the invention
In embodiment, it is only necessary to which it is all different to control the sequence number that consumable chip generates every time, it is ensured that consumable chip returns every time
