[0049] Example 1

[0050] Figure 1This is a flowchart of a serial number processing method for consumable chips according to Embodiment 1 of the present invention. This embodiment is applicable to situations where the serial number of a consumable chip in a printer needs to be switched. This method can be executed by a consumable chip serial number processing device, which can be implemented in hardware and / or software. This consumable chip serial number processing device can be configured in a printing device with data processing capabilities. Figure 1 As shown, the method includes:

[0051] S110: Obtain the write-back data of the first memory and the configuration data of the second memory.

[0052] The write-back data includes at least address data and ink volume data; the configuration data includes at least one preset ink volume data. Address data can be understood as the address corresponding to each printer in memory. In this embodiment, the address data corresponding to each printer when writing back ink volume data is determined. Ink volume data can be the remaining ink volume data after the printer's previous operation.

[0053] In this embodiment, the first memory can be a volatile memory within the consumable chip, such as Static Random Access Memory (SRAM). The write-back data of the first memory can be data obtained by the printer performing write operations on the SRAM memory within the consumable chip. The write operation involves the printer writing enable signals, write addresses, and write data to the SRAM memory. The second memory can be a non-volatile memory (NVM) within the consumable chip, such as FLASH memory. In this embodiment, the configuration data for the FLASH memory can be pre-configured. The preset ink volume data can be understood as a set threshold ink volume data, or it can be the maximum ink volume data of the consumable chip. The set threshold can be determined based on the preset ink volume data of the consumable chip. For example, in this embodiment, four preset ink volume data can be pre-configured.

[0054] In this embodiment, the SRAM memory is used to complete real-time data interaction with other modules. After power-on, it first retrieves data from the FLASH memory to complete the initialization process. When necessary, it updates the data from the SRAM memory to the FLASH memory to ensure that the chip's function can be inherited after power failure and re-power-on. The FLASH memory is used to store the code table data and related control register information required for the printer to work normally. After the consumable chip is powered on, it completes the data initialization process from the FLASH memory to the SRAM memory to ensure that the consumable chip functions normally after power-on.

[0055] In this embodiment, the address data and ink volume data written back to the SRAM memory by the printer can be obtained, and at least one preset ink volume data can be read from the FLASH memory.

[0056] S120. Determine whether the address data meets the address matching conditions.

[0057] The address matching condition can be that the address data matches at least one preset address data. In this embodiment, when a write enable signal is received, it is determined whether the address data matches at least one preset address data, i.e., whether the address matching condition is met.

[0058] In this embodiment, optionally, the configuration data includes at least one preset address data; correspondingly, determining whether the address data meets the address matching condition includes: if the address data matches at least one preset address data, then the address data meets the address matching condition.

[0059] The preset address data can be understood as pre-configured address data in the configuration data, which can be used to match the address data obtained from the write-back. In this embodiment, multiple preset address data can be configured according to actual needs. For example, four preset address data can be configured in this embodiment. In this embodiment, at least one preset address data is configured in the consumable chip. When performing address data matching, if the address data of the current write-back ink volume is the same as at least one preset address data, the address data is considered to be successfully matched and the address matching condition is met; if the address data does not match the preset address data, the address data does not meet the address matching condition.

[0060] For example, in this embodiment, four preset address data can be configured. If the address data obtained by writing back is the same as any one of the four preset address data, the address can be considered to be successfully matched.

[0061] In this embodiment, since the address data for the write-back ink volume may be different for different printers, this embodiment can use this setting to match the write-back address data with multiple preset address data, which can be compatible with multiple different printer models and is more convenient to use.

[0062] S130. If the address data meets the address matching condition, then the target data is determined based on the ink volume data and at least one preset ink volume data.

[0063] The target data can be the absolute value obtained by subtracting the ink volume data from the preset ink volume data. In this embodiment, there can be multiple target data, and the number of target data corresponds to the number of preset ink volume data.

[0064] In this embodiment, optionally, determining target data based on ink volume data and at least one preset ink volume data includes: determining the difference between ink volume data and at least one preset ink volume data to obtain at least one target data.

[0065] In this embodiment, the ink volume data can be subtracted from at least one preset ink volume data to obtain the difference, which is at least one target data. For example, in this embodiment, four preset ink volume data are configured, so the ink volume data can be subtracted from each of the four preset ink volume data to obtain four target data.

[0066] In this embodiment, by setting up such a system, multiple target data points can be identified, corresponding to consumables of different capacities, thereby achieving compatibility with different printer models and facilitating subsequent serial number switching operations based on the target data.

[0067] S140. Switch the serial number of the second memory storage area according to the target data.

[0068] The serial number in the second memory storage area can be one of multiple pre-stored serial numbers. The number of serial numbers in this embodiment can be set according to actual needs. In this embodiment, the serial number in the second memory storage area can be switched by determining whether the target data meets the set serial number switching conditions, so that the printer consumables can be successfully installed and reused.

[0069] In this embodiment, optionally, switching the serial number of the second memory storage area according to the target data includes: determining whether the target data meets the serial number switching condition; if the target data meets the serial number switching condition, then switching the serial number of the second memory storage area.

[0070] The serial number switching condition can be a condition set based on the comparison result between the target data and a set threshold. The serial number switching condition can also be a condition that needs to be met to switch the serial number of the storage area. In this embodiment, the serial number switching condition can be a pre-set condition, which can be set according to actual needs.

[0071] In this embodiment, it can be determined whether the target data meets the preset serial number switching conditions. If the target data meets the preset serial number switching conditions, the serial number of the second memory storage area can be switched; if the target data does not meet the serial number switching conditions, the serial number of the second memory storage area cannot be switched.

[0072] In this embodiment, by setting it up in this way, the serial number can be switched by judging whether the target data meets the serial number switching conditions, which can realize the reuse of consumable chips and reduce resource waste.

[0073] In this embodiment, optionally, the configuration data includes at least one set threshold, and the set threshold corresponds one-to-one with each preset ink volume data; correspondingly, determining whether the target data meets the serial number switching condition includes: determining whether the target data is greater than the corresponding set threshold; if at least one target data is greater than its corresponding set threshold, then the target data meets the serial number switching condition.

[0074] The set threshold can be a difference threshold configured based on the target data. In this embodiment, different target data have their corresponding set threshold. For example, if there are four target data, each of the four target data can have its own corresponding set threshold. Optionally, the set threshold can be set based on preset ink volume data.

[0075] In this embodiment, the system determines whether the target data is greater than the corresponding set threshold. If one of the target data is greater than its corresponding set threshold, the target data is determined to meet the serial number switching condition, and the serial number of the storage area in the second memory needs to be switched. If all the target data are less than or equal to their corresponding set thresholds, the target data is determined not to meet the serial number switching condition, and the serial number of the storage area in the second memory does not need to be switched.

[0076] Specifically, in this embodiment, if four target data are obtained by subtracting the ink volume data from four preset ink volume data, then the four target data are compared with their corresponding preset thresholds. That is, in this embodiment, there may be a first preset ink volume data, a second preset ink volume data, a third preset ink volume data, and a fourth preset ink volume data. The ink volume data is subtracted from the first preset ink volume data, the second preset ink volume data, the third preset ink volume data, and the fourth preset ink volume data to obtain the first target data, the second target data, the third target data, and the fourth target data. The first target data is compared with the first preset threshold, the second target data is compared with the second preset threshold, the third target data is compared with the third preset threshold, and the fourth target data is compared with the fourth preset threshold. If one of the following conditions is met: the first target data is greater than the first preset threshold, or the second target data is greater than the second preset threshold, or the third target data is greater than the third preset threshold, or the fourth target data is greater than the fourth preset threshold, then the ink volume data is used up, and the serial number switching condition is met. At this time, the serial number of the second memory storage area is switched. In this embodiment, the printer will report an error after the serial number switching condition is met. At this time, the printer can be powered on again to start the next boot judgment.

[0077] For example, taking a set threshold as an example, the set threshold can be 20%. One of the preset ink volume data in the memory is 100% capacity. If the ink volume data obtained by writing back is 60%, and one of the target data is 40%, then the target data exceeds the set threshold of 20%, it can be considered that the printer is abnormal, that is, the serial number switching condition is met, and the serial number needs to be switched.

[0078] In this embodiment, by judging the serial number of the consumable chip, different serial numbers can be switched when the switching conditions are met, so as to realize the reuse of the consumable chip; multiple initial ink volume preset data and multiple preset thresholds are also set to be compatible with various printer models.

[0079] The technical solution of this invention involves acquiring write-back data from a first memory and configuration data from a second memory; determining whether the address data meets the address matching condition; if the address data meets the address matching condition, determining target data based on ink volume data and at least one preset ink volume data; and switching the serial number of the storage area of ​​the second memory based on the target data. This technical solution enables the reuse of printing consumables by switching the serial number in the consumable chip based on the obtained target data.

[0080] Example 2

[0081] Figure 2 This is a flowchart of a serial number processing method for a consumable chip according to Embodiment 2 of the present invention. This embodiment is an optimization based on the above embodiment. Specifically, the optimization includes: before obtaining the write-back data of the first memory and the configuration data of the second memory, the method further includes: obtaining the stored data of the second memory; and updating the stored data from the second memory to the first memory. Figure 2 As shown, the method includes:

[0082] S210: Obtain the stored data from the second memory.

[0083] The stored data may include code table data from the memory, which contains various data stored in the memory, such as configuration data. In this embodiment, the code table data stored in the FLASH memory can be retrieved.

[0084] S220: Update the stored data from the second memory to the first memory.

[0085] In this embodiment, after the consumable chip is powered on, the code table data stored in the FLASH memory is updated to the SRAM memory. When the printer sends a read / write command, the SRAM memory is read or written according to the read / write command. Then, relevant configuration data, such as preset address data, preset ink volume data, and set thresholds, are read from the FLASH memory.

[0086] Specifically, in this embodiment, the code table data stored in the consumable chip is brand new. The code table data includes serial number information and initial ink volume information. This code table data is stored in a second memory. Each time the consumable chip is powered on, this code table data is updated to the SRAM memory for the printer to read and write. Furthermore, while the printer's read and write operations in this embodiment are performed on the SRAM memory, the data stored in the SRAM memory is lost upon power failure. Therefore, a FLASH memory is used to store the serial number data, and then the serial number data is updated to the SRAM memory upon power-on for the printer to read and write.

[0087] In this embodiment, optionally, the second memory includes a main storage area and a backup storage area; updating the stored data from the second memory to the first memory includes: determining whether the stored data in the main storage area is normal; if the stored data in the main storage area is normal, then updating the stored data in the main storage area to the first memory and the backup storage area; if the stored data in the main storage area is abnormal, then updating the stored data in the backup storage area to the first memory and the main storage area.

[0088] The main storage area can be the primary storage area of ​​the second memory. In this embodiment, the main storage area in the FLASH memory is allowed to receive write-back data from the SRAM memory. The backup storage area can be used to back up the data in the main storage area. In this embodiment, after power-on, it is determined whether the stored data in the main storage area is normal. Specifically, this can be determined by the value of the register to determine whether the main storage area is abnormal.

[0089] For example, before writing back the data, this embodiment sets the register value to 1. If the write-back is completed normally, the register value will be changed back to 0, indicating that the entire write-back process is normal, the data written back to the main storage area is normal, and the main storage area can work normally. If the write-back is not completed normally, the register value cannot be changed, that is, the register value remains at 1, which indicates that the write-back process is abnormal, the data written back to the main storage area is incorrect, the main storage area cannot work normally, and the backup storage area needs to be started.

[0090] In this embodiment, different update processes can be performed on the stored data after determining whether the stored data in the main storage area is normal. Specifically, if the chip determines that the stored data in the main storage area is normal through registers after power-on, the stored data in the main storage area will be updated to the SRAM memory (data initialization) and the backup storage area (data backup) respectively after power-on, to ensure that the stored data in the backup storage area is automatically updated to the latest normal data in the main storage area after each power-on. If the printer loses power abnormally during the data interaction (data write-back) between the main storage area and the SRAM memory, causing the data in the main storage area of ​​the FLASH memory to be abnormal, the backup storage area will be started after the next power-on. If the chip determines that the stored data in the main storage area is abnormal through registers after power-on, after obtaining the abnormal data information of the main memory, the addressing address of the FLASH memory will be changed to complete the data update (data initialization) from the backup storage area to the SRAM memory. After initialization is completed, the stored data in the backup storage area will be updated to the main storage area (data backup). The purpose is to restore the functionality of the main storage area and ensure that the data in the main storage area is restored to normal and can be used again in the future.

[0091] In this embodiment, the data interaction (data write-back) between the SRAM and FLASH memory is still based on the relationship between the main memory area and the SRAM memory. If the data write-back is still abnormal, the chip will power on again and continue to use the data stored in the backup memory area as the initial data; if the data write-back returns to normal, the chip will power on again and resume using the main memory area as the initial data. In this embodiment, the backup memory area will not receive data written back from the SRAM memory, and the data in the backup memory area will only be written to the main memory area as a backup in the event of an anomaly in the main memory area. During other processes, the data stored in the backup memory area will not change, ensuring that the data stored in the backup memory area will not be corrupted due to abnormal power outages or other reasons during use. In this embodiment, only the main memory area in the FLASH memory is allowed to receive write-back data from the SRAM memory; the backup memory area always stores normal data, effectively ensuring that the printer will not fail to recognize the device due to chip malfunction caused by data errors in the FLASH memory after each power-on.

[0092] This embodiment, through such a setting, ensures that the memory data will not be lost or corrupted due to abnormal power loss of the consumable chip during transmission, thereby improving the reliability of the consumable chip data.

[0093] S230: Obtain the write-back data of the first memory and the configuration data of the second memory.

[0094] The write-back data includes address data and ink volume data; the configuration data includes at least one preset ink volume data, at least one preset address data, and a set threshold.

[0095] S240. Determine whether the address data meets the address matching conditions.

[0096] S250. If the address data meets the address matching condition, then the target data is determined based on the ink volume data and at least one preset ink volume data.

[0097] S260. Switch the serial number of the second memory storage area according to the target data.

[0098] The technical solution of this invention involves: acquiring stored data from a second memory; updating the stored data from the second memory to a first memory; acquiring write-back data from the first memory and configuration data from the second memory; determining whether the address data meets the address matching condition; if the address data meets the address matching condition, determining target data based on ink volume data and at least one preset ink volume data; and switching the serial number of the storage area of ​​the second memory based on the target data. This technical solution ensures that the memory data will not be lost or corrupted due to abnormal power loss of the chip during transmission, improving the reliability of the chip data, and enabling the reuse of printing consumables by switching the serial number in the consumable chip based on the obtained target data.
