Above-mentioned default determining rule, for example can be it is believed that in the corresponding printing consumables of those consumable chips There is genuine piece printing consumables or printer to be previously stored with reference value of the consumable chip in terms of electrical characteristic. Firmly believe that there is the situations of genuine piece printing consumables in the corresponding printing consumables of those consumable chips, although including knowing those There is genuine piece printing consumables in the corresponding printing consumables of consumable chip, but do not know specific which or which printing consumables It is genuine piece printing consumables;Further include not just knowing that there is genuine piece printings to consume in the corresponding printing consumables of those consumable chips Material, currently it is also known that specific which or which printing consumables is genuine piece printing consumables.
In the embodiment of the detection method of the consumable chip of the present invention, above-mentioned electrical characteristic, for example can be consumptive material core The current characteristics or power characteristic of piece.In the above-described embodiments, the current characteristics of consumable chip, for example can be consumable chip Quiescent current and/or consumable chip dynamic current characteristic;The power characteristic of consumable chip therein can be consumptive material The static power characteristic of chip and/or the dynamic power characteristic of consumable chip.
When all consumable chips on printing imaging device are connected to printing imaging device by a communication bus, simultaneously The quiescent current and dynamic current characteristic for needing these chips can just learn the quiescent current and dynamic of some specific chip Electric current.Similarly, in the scheme of power characteristic, while needing the quiescent dissipation characteristic of these chips and dynamic power consumption special Property, it can just learn the quiescent dissipation and dynamic power consumption of some specific chip.Based on the respective quiescent current of each chip and dynamic Electric current or respective quiescent dissipation and dynamic power consumption, so that it may to determine whether consumable chip is original product.
It should be noted that being equal to the product of electric current and voltage in view of power, in the embodiment of the present invention, using consumptive material core The current characteristics of piece and power consumption characteristics judge to print the consistency of all consumable chips on imaging device, in technical principle It communicates, the realization method of both schemes can be referred to mutually.
Each consumable chip can be connected to printing imaging device by same communication bus.It is generally wrapped in communication bus Shared power cord VCC, ground wire GND, clock line CLK, data line I/O, reset line RESET and chip select line CS are included (chip select) etc..
As shown in Fig. 2, be sampled to the electric current in communication bus on power cord VCC, printing imaging device not with its When the respective consumable chip of printing consumables of upper installation is communicated, can according on power cord VCC voltage and sampling obtain The electric current obtained, obtains the static power of all consumable chips.The electric current obtained at this time in power cord VCC up-samplings, with the static state Power is corresponding, can be referred to as quiescent current.Electric current in communication bus on power cord VCC is sampled, it can be by setting It sets and is completed in sample circuit on power cord VCC.The sample circuit can also be arranged in printing imaging device.At it In his some embodiments, a sample circuit can be respectively set, and each sample circuit is to oneself institute on each consumable chip The electric current that the consumable chip of category is linked into communication bus on power cord VCC is sampled.
When any one of printing imaging device and those consumable chips are communicated, to power cord in communication bus Electric current on VCC is sampled, at this time according on power cord VCC voltage and the electric current that obtains of sampling, acquisition be and beat The dynamic power for that consumable chip that print imaging device is communicated and the sum of the static power of other all consumable chips. The electric current obtained at this time in power cord VCC up-samplings is that a consumable chip is communicated and remaining consumption with printing imaging device The sum of electric current when material chip is not communicated with printing imaging device.
Printing imaging device communicated one by one with all consumable chips, you can obtain these consumable chips respectively with printing The sum of the electric current of all consumable chips when imaging device is communicated.All consumable chips are led to printing imaging device respectively Letter, can obtain the sum of the electric current of the several all consumable chips equal with consumable chip quantity.For on printing imaging device When being equipped with N number of (N is the positive integer more than or equal to 2) printing consumables, the quantity of corresponding consumable chip is also N.Printing imaging The sum of the electric current of these consumable chips that equipment obtains when only being communicated with first consumable chip is calculated as I1, and printing imaging is set It is calculated as I2 for the sum of the electric current of these consumable chips obtained when only being communicated with second consumable chip ..., printing imaging The sum of the electric current of these consumable chips that equipment obtains when only being communicated with n-th of consumable chip is calculated as In.Wherein, Ii is to beat The dynamic current and remaining N-1 consumptive material core of i-th of consumable chip when print imaging device is communicated with i-th of consumable chip The sum of quiescent current of piece, 1≤i≤N.
If the electric current for all consumable chips that printing imaging device obtains when being communicated one by one with all consumable chips The sum of be equal, namely as I1=I2=... when=In=...=IN, it may be considered that all consumable chips are in current characteristics On be consistent.If known in this N number of printing consumables in advance some or certain it is several be genuine piece really, can will These are consistent all consumable chips on current characteristics, and respectively corresponding printing consumables is confirmed as genuine piece.
Printing imaging device communicated one by one with all consumable chips, you can obtain these consumable chips respectively with printing The sum of the power of all consumable chips when imaging device is communicated.All consumable chips are led to printing imaging device respectively Letter, can obtain the sum of the power of the several all consumable chips equal with consumable chip quantity.For on printing imaging device When being equipped with N number of (N is the positive integer more than or equal to 2) printing consumables, the quantity of corresponding consumable chip is also N.Printing imaging The sum of the power of these consumable chips that equipment obtains when only being communicated with first consumable chip is calculated as W1, and printing imaging is set It is calculated as W2 for the sum of the power of these consumable chips obtained when only being communicated with second consumable chip ..., printing imaging The sum of the power of these consumable chips that equipment obtains when only being communicated with n-th of consumable chip is calculated as Wn.Wherein, Wi is to beat The dynamic power and remaining N-1 consumptive material core of i-th of consumable chip when print imaging device is communicated with i-th of consumable chip The sum of static power of piece, 1≤i≤N.
If the power for all consumable chips that printing imaging device obtains when being communicated one by one with all consumable chips The sum of be equal, namely as W1=W2=... when=Wn=...=WN, it may be considered that all consumable chips are in power characteristic On be consistent.If known in this N number of printing consumables in advance some or certain it is several be genuine piece really, can will These are consistent all consumable chips in power characteristic, and respectively corresponding printing consumables is confirmed as genuine piece.
If the power for all consumable chips that printing imaging device obtains when being communicated one by one with all consumable chips The sum of not necessarily all equal namely W1, W2 ..., Wn ... and have in WN part it is unequal when, then illustrate that these consumable chips exist It is inconsistent in power characteristic, at this time it may be considered that in printing consumables corresponding to these consumable chips, there is part printing Consumptive material may have any different with other printing consumables.If known in this N number of printing consumables in advance some or certain it is several Really be genuine piece, then can according to this genuine piece with print all consumable chips when imaging device be communicated power it With or these genuine pieces respectively communicated with printing imaging device when all consumable chips the sum of power, which to be determined Printing consumables may be fakement.
If it is believed that p-th of (1≤p≤N) printing consumables is genuine piece in N number of printing consumables, p-th of printing consumables Corresponding consumable chip is communicated with printing imaging device and remaining N-1 consumable chip is not carried out with printing imaging device The sum of power when communication is Wp, then within the scope of error allows, the consumable chip corresponding to other N-1 printing consumables Respectively with the sum of the power that is communicated of printing imaging device, corresponding consumable chip may be considered that and pth when equal with Wp The consumable chip of a printing consumables is consistent, with Wp it is unequal when corresponding consumable chip may be considered that and p-th of printing consumes The consumable chip of material is inconsistent.
Further, corresponding to consistent with the consumable chip of p-th of printing consumables that or those consumable chip Printing consumables, be considered genuine piece;Inconsistent that or those consumptive material with the consumable chip of p-th of printing consumables Printing consumables corresponding to chip, is considered fakement.
All consumable chips are connected to the situation of printing imaging device by a communication bus, it can be assumed that this dozen Printing setting on imaging device, there are three printing consumables, and corresponding there are three consumable chips.The respective quiescent dissipation of these three chips point Not Wei K1, K2 and K3, then total quiescent dissipation W0=K1+K2+K3.When only reading and writing first consumable chip, these three consumptive materials The respective power consumption of chip is respectively D1, K2 and K3, power consumption W1=D1+K2+K3 total at this time.No matter the second consumable chip and third Consumable chip whether genuine piece, W1-W0=D1-K1, this result is the static-dynamic power consumption (dynamic power consumption of first consumable chip With the difference of quiescent dissipation), it is only related with first consumable chip.And so on, also can get second consumable chip and The respective static-dynamic power consumption of third consumable chip.To which all consumable chips printed on imaging device are total by a communication When line is connected to printing imaging device, the static-dynamic power consumption of each consumable chip can be specifically determined, and then judge each consumption Whether material chip is original product.
It is specifically applied at one in test case, it is assumed that the consumptive material of an ink-jet printer includes tetra- colors of C, M, Y and K Print cartridge, each print cartridge is separately installed with the consumable chip of C, M, Y and K type.This four consumable chips are total by a communication Line is connected to printing imaging device.When ink-jet printer is not read out any one consumable chip or when write operation, The electric current Is0 on power cord VCC can be obtained by sampling circuit samples can obtain in conjunction with the voltage on power cord VCC The quiescent dissipation Ws0 of all consumable chips.
When ink-jet printer carries out write operation to consumable chip Y, sampling obtains the electric current Is1 on power cord VCC, then In conjunction with the voltage on power cord VCC, the quiescent dissipation of C, M and K consumable chip and the dynamic work(of Y consumable chips can be obtained at this time The sum of consumption Ws1.
Then, ink-jet printer stops that consumable chip Y is written, and changes into carry out write operation to C, M and K respectively, and divide The sum of the power consumption under situation Ws2, Ws3 and Ws4 Ji Suan not corresponded to.As error (such as ± 5%) interior expression formula Ws1=in permission When Ws2=Ws3=Ws4 is set up, it may be considered that the electrical characteristic of this four consumable chips is consistent, and this four consumptions are can consider Material chip is same manufacturer's design production, or is also believed that this four consumable chips are the same batches of the manufacturer Product.
It is not to be connected to printing imaging by a communication bus to set if printing all consumable chips on imaging device It is standby, but each consumable chip is respectively independently-powered, then can only pass through the quiescent dissipation of each in these consumable chips Or dynamic power consumption, so that it may with realize whether be sentencing for original product to all consumable chips on same printing imaging device It is disconnected to determine.For example, be both powered up to all consumable chips on same printing imaging device, but when without read-write operation, respectively The corresponding power of chip is the respective static power of each consumable chip.If wherein have the quiescent dissipation of part consumable chip with The quiescent dissipation difference of other consumable chips is larger and exceeds preset judgement range, then can determine on the printing imaging device Consumable chip it is inconsistent.If can determine that portioned product is original product, the inconsistent consumptive material with these original products Chip is clone (also being understood as fakement).Certainly, it also sets up in turn, namely if can determine that portioned product is Clone, then the consumable chip inconsistent with these clones is original product (i.e. above-mentioned genuine piece).
When all consumable chips on printing imaging device are all independently-powered, only by each in these consumable chips A dynamic power consumption can also be realized to whether all consumable chips on same printing imaging device are sentencing for original product It is disconnected to determine.For example, being both powered up to all consumable chips on same printing imaging device, and each consumable chip is carried out successively Read-write, the corresponding power of each chip are the respective dynamic power of each consumable chip.If wherein there is the dynamic of part consumable chip State power consumption differs larger with the dynamic power consumption of other consumable chips and exceeds preset judgement range, then can determine that this is printed as As the consumable chip in equipment is inconsistent.If can determine that portioned product is original product, differ with these original products The consumable chip of cause is clone (also being understood as fakement).Certainly, it also sets up in turn, namely if can determine portion It is clone to divide product, then the consumable chip inconsistent with these clones is original product.By quiescent current or Dynamic current come realize to all consumable chips on same printing imaging device whether be original product judgement determine, can To use similar method.
In the embodiment of the detection method of the consumable chip of the present invention, above-mentioned electrical characteristic, for example can also be consumptive material The capacitance characteristic of chip namely the charge characteristic of consumable chip and/or flash-over characteristic.By carrying out charge and discharge simultaneously to consumable chip It is whether consistent on capacitance characteristic can to obtain different consumable chips for the charge-discharge characteristic for recording consumable chip.
Then stop powering for example, powering to consumable chip, the ends VCC of consumable chip are sampled in real time, so that it may with Charge characteristic when consumable chip rises to second voltage from first voltage is obtained, and drops to the 4th voltage from tertiary voltage When flash-over characteristic.Wherein, second voltage is more than first voltage, and tertiary voltage is more than the 4th voltage;Second voltage can be with Three voltages are equal, the magnitude relationship that can not determined between first voltage and tertiary voltage, which such as can be 0 Volt (V).
Wherein, above-mentioned charge characteristic such as can be charging duration, can also be according to charging duration and voltage value shape At boosting curve.Above-mentioned flash-over characteristic such as can be electric discharge duration, can also be according to electric discharge duration and voltage value shape At drawdown curve.
All consumable chips are connected to the situation of printing imaging device by a communication bus, it can be in each consumption One charge and discharge switch (connection capacitance or capacitive module etc.) is set on material chip.Before carrying out charge-discharge test, printing Imaging device sends switch order to control the break-make of the charge and discharge switch on each chip by elder generation to each consumable chip, thus Realize the independent charge and discharge to each consumable chip.
It, can be straight to wherein each consumable chip when all consumable chips on printing imaging device are all independently-powered Tap into row charge-discharge test.
Fig. 3 is shown charges and discharges the buck curve synoptic diagram to be formed to a consumable chip.It is wherein vertical to sit Voltage (V) on mark mark consumable chip, abscissa indicate time T.On the vertical scale, show a consumable chip from 0 volt Spy boosts to V1 volts of process, and 0 volt of process is depressurized to from V1 volts.On the horizontal scale, 0 moment is to T1 timetables Show the process to charge to the consumable chip, the process for indicating to discharge to the consumable chip from the T1 moment to the T2 moment.
For multiple consumable chips on same printing imaging device, as long as setting identical first voltage, second Voltage, tertiary voltage and the 4th voltage, and use identical power supply and method of supplying power to, then it can be by each consumptive material The charge characteristic and/or flash-over characteristic of chip, so that it may to learn whether these consumable chips are consistent on capacitance characteristic.
One by one to being printed as all consumable chips progress charge and discharge in equipment and obtaining respective capacitance characteristic, if The capacitance characteristic obtained respectively under the conditions of the same detection of these consumable chips is consistent, then illustrates that these consumable chips are consistent 's.If the capacitance characteristic obtained respectively under the conditions of the same detection of these consumable chips is inconsistent, illustrate these consumptive material cores There is differences with other consumable chips for part in piece.
If known in these printing consumables in advance some or certain it is several be genuine piece really, can be according to this The capacitance characteristic or the respective capacitance characteristic of these genuine pieces of one genuine piece, to determine which printing consumables may be fakement.
Further, corresponding to capacitance characteristic that or those consumable chip consistent with the consumable chip of genuine piece Printing consumables is considered genuine piece;Inconsistent that or those the consumptive material core of the consumable chip of capacitance characteristic and genuine piece Printing consumables corresponding to piece, is considered fakement.
