The specific embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
From prior art as can be seen, has the reason that the non-standard capacity ink box of the storage chip that resets can't use in print procedure, mainly be exactly because the existing storage chip that resets can't be discerned the data of the sign recording material capacity that detecting information comprised of the data of true sign recording material capacity and printing equipment setting, can't carry out different processing at detecting information and the true data that characterize recording material capacity, can not be thereby cause when printing equipment is verified by causing.
Therefore, in order to overcome this defective, the present invention proposes a kind of storage chip, this storage chip is arranged on the non-standard capacity ink box, in print procedure, this storage chip can be discerned the data and the true data that characterize recording material capacity of the sign recording material capacity that detecting information comprised of setting.Storage chip carries out following processing to the data of the sign recording material capacity that is written into: the data that store the sign recording material capacity that writes earlier, whether meet or exceed the reset gate limit value of setting then according to the data of the sign recording material capacity that writes, determine whether to reset to the initial value that resets again, the data of the sign recording material capacity after will handling then store.When printing equipment writes the detecting information that comprises the data that characterize recording material capacity of setting and during follow-up reading, storage chip identifies, and directly this stored test data is read to printing equipment then; When printing equipment writes the data of true sign recording material capacity and during follow-up reading, storage chip identifies, the true sign recording material capacity after will handling then reads to printing equipment.
Therefore, method provided by the invention and storage chip, even printing equipment is verified the storage chip of non-standard capacity ink box provided by the invention, can not reset yet and cause checking not pass through owing to the data of the sign recording material capacity that the detecting information that writes is comprised.In addition, when printing equipment write the data of true sign recording material capacity, whether storage chip also can surpass the reset gate limit value that is provided with according to these true data that characterize recording material capacity determined whether and will reset.Like this, the data according to the sign recording material capacity that stores in method provided by the invention and the device adjustment storage chip are normally used non-standard capacity ink box.
Fig. 2 for the printing equipment with authentication function of the present invention in print procedure and the method flow diagram of the storage chip single exchange information of normal capacity print cartridge, its concrete steps are:
Before this step, after the printing of last once printing equipment, printing equipment can write the data that truly characterize recording material capacity storage chip and store, use during in order to current printings;
In this step, when printing equipment was printed first, printing equipment reads was the data of the sign recording material capacity that prestores of storage chip, and this data representation print cartridge is full China ink amount;
Step 202, printing equipment carry out current printing, the detecting information that will comprise the data that characterize recording material capacity is written to storage chip, the data of the true sign recording material capacity of write-once storage chip before covering, and then read checking from storage chip, if with write identical, then by checking, execution in step 203; Otherwise not by checking, alarm and control stop printing;
As can be seen from Figure 2, printing equipment is in print procedure, detecting information is write the authenticity that storage chip is used to verify the storage chip storage data, because the data of the sign recording material capacity that comprises in this detecting information are not real, so carry out corresponding reset processing after can not judging according to the reset gate limit value, otherwise will cause checking not pass through.
But, from Fig. 2 also as can be seen, printing equipment reads the time between the detecting information that characterizes recording material capacity of comprising that writes setting after the data verification of true sign recording material capacity again, compare with the time between the data that write or read true sign recording material capacity after the data verification of reading true sign recording material capacity once more, be far smaller than.Therefore, the storage chip of non-standard capacity ink box provided by the invention just utilizes this characteristic, the data of the sign recording material capacity that detecting information comprised that identification is provided with and the true data that characterize recording material capacity.
As shown in Figure 3, Fig. 3 is the method flow diagram of data of the sign recording material capacity of adjustment print cartridge provided by the invention, time period is set on storage chip in advance, the duration of this time period write again after more than or equal to the data verification of reading true sign recording material capacity setting comprise time between the detecting information that characterizes recording material capacity, less than the time between the data that write or read true sign recording material capacity after the data verification of reading true sign recording material capacity once more, its subsequent step is:
Step 301, after data that printing equipment will characterize recording material capacity write storage chip, storage chip stores above-mentioned data;
In this step, the data that characterize recording material capacity may also may be the data of the sign recording material capacity in the set detecting information for the true data that characterize recording material capacity;
In this step, also number of resets can be set, whenever current number of resets increasing or decreasing resets once, met or exceeded the thresholding that resets of setting when the data of judging this sign recording material capacity after, further comprise, judge whether current number of resets reaches the number of resets of setting, if, execution in step 304; If not, execution in step 303;
In this step, the setting of reset gate limit value does not reach the value of recording materials surplus deficiency in the normal capacity print cartridge that printing equipment assert, number of resets is set with respect to the recording material capacity difference of normal capacity print cartridge according to non-standard capacity ink box;
Step 303, the storage chip initial value that will reset stores execution in step 305 as the data that storage chip characterizes recording material capacity;
In this step, the initial value that resets is that the China ink amount of signature criteria capacity ink box is full data, perhaps the data of the sign of overgauge capacity ink box identification China ink quantity not sufficient and be full data smaller or equal to the China ink amount;
Like this, the one side printing equipment is when test has the non-standard capacity ink box of this storage chip, and is identical with the detecting information that writes owing to reading, so checking is passed through; On the other hand, in print procedure, the data that storage chip that printing equipment reads characterizes recording material capacity are exactly the data that truly characterize recording material capacity, this data representation the capacity abundance of non-standard capacity ink box, then can continue to print.
In step 301, when the data of the sign recording material capacity that writes are the data of the sign recording material capacity that detecting information comprised, when step 303 stores, also store other parameters that detecting information comprises, when step 305 reads, go back other parameters that read test information comprises and verify.
Correspondingly, the present invention also provides the storage chip of the data of the sign recording material capacity of adjusting print cartridge, as shown in Figure 4, comprises timing unit and memory cell, wherein,
Timing unit, be used to be provided with the time period, the duration of time period write again after more than or equal to the data verification of reading true sign recording material capacity setting comprise time between the detecting information that characterizes recording material capacity, less than the time between the data that write or read true sign recording material capacity after the data verification of reading true sign recording material capacity once more, when storage chip is printed the device power down, pick up counting;
Memory cell, the data that are used for the sign recording material capacity that the storage print device writes, judge whether the data of this sign recording material capacity meet or exceed the reset gate limit value of setting, if, the initial value that resets stores as the data that storage chip characterizes recording material capacity, if not, these data that characterize recording material capacity store as the data that storage chip characterizes recording material capacity; Receive the time period that the time between twice operation signal that printing equipment sends is provided with smaller or equal to timing unit, the data of this sign recording material capacity are printed device and read; Otherwise the data of storage chip sign recording material capacity are printed device and read.
In Fig. 4, memory cell stores as the data that storage chip characterizes recording material capacity at the initial value that will reset, also be used for further judging whether current number of resets is the number of resets that reaches setting, current number of resets is executing the back that once resets according to setting increasing or decreasing, if then the data with stored sign recording material capacity store as the data that storage chip characterizes recording material capacity; If not, the initial value that then will reset stores as the data that storage chip characterizes recording material capacity.
In the present invention, timing unit generally is made up of power storage module, comprises electric capacity, and the electric weight of electric power storage is determined that by capacitance the duration of this capacitor discharge is then determined by the time period of setting; Memory cell is made of volatile memory, comparison module and nonvolatile memory.Printing equipment write characterize recording material capacity data behind storage chip, stop the storage chip power supply, and then when reading or writing information, again storage chip powered to storage chip.The storage chip power down is equaled to write the data of true sign recording material capacity or the time of detecting information again after printing equipment is read the detecting information checking to the supplying time section; After perhaps the printing equipment data that will truly characterize recording material capacity are read checking, write or read the time of the data of true sign recording material capacity once more.Power storage module just utilizes printing equipment to the storage chip store electrical energy that powers on, continue to power with the electric energy that stores during at printing equipment then to the storage chip power down to memory cell, because the time that this electric energy continues is more than or equal to the time period of setting, promptly this electric energy duration writes the time between the detecting information that characterizes recording material capacity of comprising of setting after more than or equal to the data verification of reading true sign recording material capacity again, less than the time between the data that write or read true sign recording material capacity after the data verification of reading true sign recording material capacity once more, so the present invention just can utilize this point to determine when printing equipment reads data, storage chip should the still true data that characterize recording material capacity of feedback test data.
Particularly, as shown in Figure 5, Fig. 5 is the storage chip specific embodiment schematic diagram of data of the sign recording material capacity of adjustment print cartridge provided by the invention, comprising: power storage module, volatile memory, comparison module and nonvolatile memory, wherein,
Power storage module, be used for store electrical energy when printing equipment powers on to storage chip, the charge capacity of this store electrical energy determined by capacitance, and the capacitance discharge period determined by the time period that is provided with, and with stored electric energy described memory cell powered during to the storage chip power down at printing equipment;
Volatile memory is used to be written into the data that characterize recording material capacity and stores, and the data of this sign recording material capacity are sent to comparison module; Having under the electricity condition, the data of this sign recording material capacity that stores are printed device and read, from electricity condition being arranged to power-down state, lose the data of this sign recording material capacity of storage, electricity condition is arranged again, after storage chip in the nonvolatile memory characterizes that the data of recording material capacity are controlled and uploads to volatile memory, be printed device to read;
Comparison module, be used to judge whether the data that characterize recording material capacity meet or exceed the reset gate limit value of setting, if, the initial value that will reset is stored in the nonvolatile memory as the data that storage chip characterizes recording material capacity, if not, the data that characterize recording material capacity are stored in the nonvolatile memory as the data that storage chip characterizes recording material capacity.
In this storage chip, between volatile memory and nonvolatile storage, also comprise control module, be used to carry out the data interaction of being stored between volatile memory and the nonvolatile storage, particularly, can control volatile memory uploads to the storage chip sign recording material capacity of storing in the nonvolatile storage on the volatile memory.
Comparison module in Fig. 5 also is used for the data that the initial value that resets characterizes recording material capacity as storage chip are stored into before the nonvolatile memory, judge whether current number of resets reaches the number of resets of setting, current number of resets is executing the back that once resets according to setting increasing or decreasing, if the initial value that will reset is stored in the nonvolatile memory as the data that storage chip characterizes recording material capacity; If not, the data that characterize recording material capacity are stored in the nonvolatile memory as the data that storage chip characterizes recording material capacity.
Like this, characterize the transmission of the data of recording material capacity between printing equipment and the volatile memory, when the data that write the sign recording material capacity of volatile memory when printing equipment met or exceeded the reset gate limit value of setting, comparison module will be written to the initial value that resets that is provided with in the nonvolatile memory as the data that storage chip characterizes recording material capacity.When storage chip is printed the device power down, by power storage module memory cell is powered, when power storage module storage chip behind discharge off was printed device again and powers on, the data that the storage chip in the nonvolatile memory characterizes recording material capacity will write volatile memory.At this time, printing equipment will reflect the ink capacity abundance from the data that volatile memory reads storage chip sign recording material capacity, this storage chip characterizes recording material capacity and is true sign recording material capacity, and then printing equipment is proceeded printing.If printing equipment writes the data of the sign recording material capacity that the data of the sign recording material capacity of volatile memory comprise for the detecting information that is provided with, and meet or exceed the reset gate limit value of setting, though the initial value that resets that nonvolatile memory will be provided with writes as the data that storage chip characterizes recording material capacity, but before the power storage module discharge off, the data of the sign recording material capacity that writes for printing equipment of volatile memory stores, so what printing equipment read is the data of the sign recording material capacity of volatile memory stores, printing equipment verifies that this storage chip can pass through like this.After printing equipment will characterize recording material capacity once more after detecting information checking the data data of true sign recording material capacity (at this time for) write volatile memory to the storage chip power down, the data of this sign recording material capacity are through truly being characterized the data of recording material capacity after the processing of comparison module and being written in the nonvolatile memory, when after power storage module discharge finishes, being printed device once more and powering on, the data of the true sign recording material capacity of non-volatile memory storage can write volatile memory again and be printed device and read, owing to should truly characterize the China ink amount abundance of the data reflection non-standard capacity ink box of recording material capacity, printing equipment just can not stop to print or the indication user changes print cartridge.
