Fig. 1 is a block diagram of a consumable chip according to an embodiment of the present invention. As shown in FIG. 1, the consumable chip 100 includes a memory 110, a register 120, and a logic circuit 130.
The memory 110 includes a backup area 111, a code table area 112, and a configuration area 113. The memory 110 is electrically connected to the register 120, and is configured to read the configuration data and write the configuration data into the register 120 when the consumable chip 100 is powered on. For example, the memory 110 is a non-volatile memory. The storage space provided by the memory 110 includes a backup area 111, a code table area 112, a configuration area 113, and the like. The address ranges of the backup area 111, the code table area 112, and the configuration area 113 do not overlap. The backup area 111 is used for storing backup data of initial data of the code table area 112, the code table area 112 is used for storing code table data for realizing a printing function, the code table data for realizing the printing comprises ink amount data, and the configuration area 113 is used for storing configuration data.
It should be noted that the configuration data is data for reset monitoring and/or serial number updating, which is written in advance in the memory. The configuration data includes data such as a reset generation condition, a serial number change flag, a serial number address, an ink volume address, and a reset condition flag. Optionally, the number of the ink volume addresses and the serial number addresses may be preset according to actual application requirements, so that multiple sets of ink volume monitoring mechanisms are simultaneously effective, and addressing requirements of different imaging devices can be met during use. For example, it is possible that the configurations 21, 22, 23, and 24 are all ink volume addresses, and the configurations 31, 32, 33, and 34 are all serial number addresses. The ink amount address of the image forming apparatus a is 21, the serial number address is 32, and when the consumable container mounted with the consumable chip 100 is used in the image forming apparatus a, the image forming apparatus a reads the serial number from the address 32 and writes back the ink amount data to the address 21. The ink amount address of the image forming apparatus B is 22, the serial number address is 33, and when the consumable container mounted with the consumable chip 100 is used in the image forming apparatus B, the image forming apparatus B reads the serial number from the address 33 and writes back the ink amount data to the address 22.
The value of the reset generation condition is used to indicate under which condition the reset is generated. For example, if the reset generation condition is configured, it is possible to know the ink amount threshold, and whether the chip reset is performed when the current ink amount data is larger than the ink amount threshold, or the chip reset is performed when the current ink amount data is equal to the ink amount threshold, or the chip reset is generated when the current ink amount data is smaller than the ink amount threshold.
The serial number change flag is used to indicate whether the consumable chip 100 needs to update the serial number during the reset process.
The serial number address is used to indicate the storage location of the serial number.
The ink amount address is used to indicate a storage location of the ink amount data.
The reset condition flag bit is used to indicate which of the above-described reset generation conditions is used to generate a reset.
The code table area 112 is used for storing code table data for implementing a printing function, which is code table data written to the consumable chip 100 that can be recognized by the image forming apparatus and implements an image forming function. For example, the code table data includes data such as a serial number and ink amount data. The backup area 111 is a backup of the code table area 112, and when it is judged that the ink amount data meets the reset condition, the original code table data is replaced with the backup data in the backup area 111. Note that the backup data in the backup area 111 is identical to the original data in the code table area 112. The original data of the code table area 112 refers to the initial values written in the code table area 112 when the chip is shipped. The reason why the backup data in the backup area 111 is required to be consistent with the original data in the code table area 112 is that: when the image forming apparatus writes back the consumable chip 100, the remaining data in the code table is rewritten in addition to the ink amount data, and the backup data in the backup area 111 is designed to be identical to the initial write data in the code table area 112 in order to ensure that the reset data is completely new data.
The configuration data in the configuration area 113 is written to the register 120 when the consumable chip 100 is powered on. Specifically, when the consumable chip 100 is installed on the consumable container, and the consumable container is installed on the imaging device, the imaging device is connected with the communication interface of the consumable chip 100 through the communication interface, so as to supply power to the consumable chip 100 through the communication interface, and at this time, the consumable chip 100 is powered on. After the consumable chip 100 is powered on, the read/write circuit of the memory 110 reads the configuration data in the configuration area 113 and writes the configuration data into the register 120. During operation of the image forming apparatus, consumables in the consumable container are consumed along with an image forming operation of the image forming apparatus. The image forming apparatus writes back the consumable chip 100 according to the control timing to update the ink amount data in the code table area 112. It should be noted that, when the image forming apparatus writes back the ink amount data, it is also possible to modify other code table data in the code table area 112.
Specifically, the image forming apparatus reads the ink amount data from the code table area 112 based on the ink amount address, and performs a write-high or write-low operation on the ink amount data. Taking an inkjet printer as an example, the write-back operation of the ink amount is different for different types of inkjet printers. There are ink jet printers in which high ink amount data is written with use, in which case the initial ink amount data is 0, and the ink amount data gradually increases with the write back operation of the ink jet printer. Some inkjet printers write low ink amount data with use, in which case the initial ink amount data is full ink amount, and the ink amount data gradually decreases with the write-back operation of the inkjet printer.
In order to avoid the situation that the write back operation in different directions causes the chip reset misjudgment based on the ink amount data and the ink amount threshold value, the adopted reset generation condition is distinguished through the reset condition flag bit. For example, when the write-back operation of the ink jet printer is write-high, the reset condition flag is configured to be a first value indicating that the reset generation condition is adopted when the current ink amount data is greater than the ink amount threshold, it is determined that the ink amount data meets the reset condition. When the write-back operation of the ink jet printer is write-low, the reset condition flag bit is configured to be second data indicating that the reset generation condition is adopted when the current ink amount data is less than the ink amount threshold value, and it is determined that the ink amount data meets the reset condition. When the configuration reset condition flag is a third value, indicating that the reset generation condition is adopted is that the current ink amount data is equal to the ink amount threshold, it is determined that the ink amount data meets the reset condition.
The logic circuit 130 is electrically connected to the memory 110 and the register 120, respectively, and is configured to read the ink amount data and the configuration data, monitor whether the ink amount data meets a reset condition based on the configuration data, shield feedback data to the image forming apparatus when the ink amount data meets the reset condition, and replace the code table data in the original code table area 112 with backup data.
FIG. 2 is a block diagram of another consumable chip according to an embodiment of the present invention. As shown in fig. 2, the logic circuit includes an ink amount detection circuit 233, a first read-write circuit 231, a second read-write circuit 232, and a feedback circuit 234.
The first read/write circuit 231 is electrically connected to the register 120 and the ink amount detection circuit 233, respectively. The first read/write circuit 231 is configured to read the ink volume address, the ink volume threshold, and the reset condition flag bit in the configuration data, output the ink volume address, the ink volume threshold, and the reset condition flag bit to the ink volume detection circuit 233, so as to read the current ink volume data from the code table area 112 of the memory 110 through the ink volume detection circuit 233 based on the ink volume address, compare the ink volume data with the ink volume threshold, obtain a comparison result, and determine whether the current ink volume data meets the reset condition in combination with the reset condition flag bit.
The second read/write circuit 232 is electrically connected to the memory 110, and is configured to read the backup data of the memory 110 and write the backup data into the primary code table area 112 of the memory 110. Specifically, when the reset flag is a signal indicating that the second read/write circuit 232 is enabled, the second read/write circuit 232 is activated by the reset flag signal output from the ink amount detection circuit 233, reads the backup data from the memory 110 based on the address of the backup area 111, and writes the backup data in the memory 110. The memory 110 writes the backup data into the code table area 112 according to the address of the code table area 112 to replace the code table data of the original code table area 112 with the backup data.
The ink amount detection circuit 233 is electrically connected to the feedback circuit 234 and the second read/write circuit 232, and configured to compare the ink amount data with the ink amount threshold according to the ink amount data in the ink amount address reading code table area 112, generate a reset identification signal according to the comparison result and the reset condition flag, and output the reset identification signal to the feedback circuit 234 and the second read/write circuit 232, where the reset identification signal is used to enable the feedback circuit 234 and the second read/write circuit 232. Specifically, the reset flag signal includes a signal to disable the feedback circuit 234 when the ink amount data meets the reset condition, and a signal to enable the feedback circuit 234 when the ink amount data does not meet the reset condition.
And a feedback circuit 234 for sending feedback data to the imaging device. Wherein the feedback data is code table data that feeds back imaging device commands. Specifically, when the reset identification signal is a signal that enables the feedback circuit 234, the feedback circuit 234 transmits feedback data to the image forming apparatus in a clock cycle corresponding to the feedback operation. For example, the feedback circuit 234 outputs feedback data to the imaging device in a clock cycle corresponding to the feedback operation. If the feedback circuit 234 normally feeds back the imaging device command, the consumable chip 100 can be normally authenticated and printed. It should be noted that if the feedback circuit 234 cannot normally feed back the command of the imaging device, the imaging device waits for a predetermined clock period and then reports an error. In the embodiment of the present invention, the condition that the feedback circuit 234 abnormally feeds back the command of the image forming apparatus may be that the feedback circuit 234 does not work, or that the feedback circuit 234 is disabled.
After the imaging equipment reports an error, prompt information for re-plugging the consumable container can be displayed on the imaging equipment. Plugging and unplugging the consumable container can cause the consumable chip 100 to be powered up after power failure. When the consumable chip 100 detects the insertion and extraction of the consumable container, it is determined that the consumable chip itself has been reset.
According to the technical scheme, whether the current ink amount data accord with the reset condition or not is monitored through the logic circuit based on the configuration data, when the ink amount data accord with the reset condition, the feedback data of the imaging equipment is shielded, when the feedback data is shielded, the backup data is adopted to replace the code table data in the original code table area, when the ink amount data reaches the loss limit value, the automatic reset is executed while the feedback data is shielded, sufficient time is provided for chip reset, the condition that the power is lost when the chip is not reset is avoided, and the accuracy of the chip reset is ensured while the chip reset efficiency is improved.
On the basis of the above technical solutions, the embodiment of the present invention specifically defines the timing for executing the reset. Deactivating the feedback circuit when the reset identification signal is a signal to deactivate the feedback circuit; the second read-write circuit is used for reading the backup data of the memory and writing the backup data into the original code table area of the memory in a time period from the end of the clock cycle corresponding to the feedback operation to the receipt of the next command of the imaging device. The advantage of design like this is that the chip resets at the mutual in-process simultaneous execution chip of consumptive material chip and imaging device, because imaging device can not cut off the power supply when interacting with the consumptive material chip, consequently, guarantee that the consumptive material chip carries out the power supply of the operation overall process that resets, avoid appearing because of the consumptive material chip falls the power failure and complete the resetting of not, and the consumptive material chip mistake deems as the condition of accomplishing that resets, this kind of condition can lead to imaging device to go up the electric back and discern that the consumptive material chip is used chip and can not normally print.
On the basis of the above technical solutions, the embodiments of the present invention further limit the logic circuit.

The advantage of the design is that reset judgment is executed by multiplexing the process of power-on initialization of the imaging device 200 or the process of ink volume address write-back of the imaging device 200, so that the situation that a single clock cycle is occupied for judging reset is avoided, and the processing efficiency of the consumable chip 100 is improved.

During use of the ink jet printer 400, the ink jet printer 400 constantly consumes printing ink, and the printer constantly writes back the ink volume address of the cartridge chip as the ink volume is consumed to update the ink volume data at the ink volume address. At this time, the ink amount detection circuit 333 inside the cartridge chip monitors the ink amount data. When the ink amount data does not meet the reset condition, the ink box chip normally feeds back a printer command, and at the moment, the ink box chip can normally recognize and print. The consumable chip 100 performs printer feedback through the feedback circuit 334 based on the code table data in the code table area 112. When the ink volume data meets the reset condition, the cartridge chip will mask the feedback data to the inkjet printer 400. At this time, the cartridge chip starts writing the backup area data into the code table of the code table area 112.
If the serial number change flag bit indicates that the serial number needs to be updated, the cartridge chip also automatically generates a new serial number based on the original serial number through the serial number change circuit 337. In a clock interval after the data in the backup area is written into the code table, a new serial number is written into the code table to replace the original serial number in the code table, and then the serial number changing circuit 337 enters a deactivated state. If the serial number change flag indicates that no serial number update is required, the serial number change circuit 337 continues to be disabled.
After the error is reported by the inkjet printer 400, a prompt message for re-inserting and removing the consumable container is displayed on the inkjet printer 400. Plugging and unplugging the consumable container can cause the consumable chip 100 to be powered up after power failure. When the consumable chip 100 detects the insertion and extraction of the consumable container, it is determined that the consumable chip itself has been reset.
Fig. 5 is a timing diagram of a control of a consumable chip according to an embodiment of the present invention. As shown in fig. 5, after the ink jet printer is powered on, the ink jet printer executes a read command during the first clock cycle in the figure. The ink box chip monitors ink quantity data, and when the ink quantity data does not meet the reset condition, the ink box chip sends feedback data to the ink-jet printer in a second clock period, and the ink-jet printer can normally recognize and print the ink.
FIG. 6 is a timing diagram illustrating another control of a consumable chip according to an embodiment of the present invention. As shown in fig. 6, after the ink jet printer is powered on, the ink jet printer executes a read command during a first clock cycle in the figure. The ink box chip monitors ink quantity data, when the ink quantity data meet a reset condition, the basin and the chip shield feedback data of the ink-jet printer in a second clock period, and after the second clock period is finished, the ink box chip starts to write backup data in the backup area into the code table area and automatically generates a serial number for replacement.
Because the feedback data of the ink-jet printer is shielded, the ink-jet printer can report an error and prompt the ink box to be plugged again after waiting for a set clock period. After the ink box is plugged again, the ink box chip finishes resetting and serial number changing, so the ink box can be identified by the ink-jet printer, the ink quantity data does not accord with the resetting condition, the process shown in the figure 5 is executed, and normal machine identification and printing are carried out.
