All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a data compression and storage method for an ink cartridge chip according to an embodiment of the present invention. The data compression and storage method of the ink box chip comprises the following steps:
step S1, compressing at least one set of ink box characteristic data to obtain and store an ink box characteristic data set containing at least one set of compressed data, and selecting one set of compressed data from the ink box characteristic data set for executing ink box authentication and ink box record acquisition work;
step S2, obtaining the use progress status information of one group of the compressed data, and determining the address information corresponding to another group of the compressed data obtained from the ink box characteristic data set in the next step according to the use progress status information;
in step S3, another set of compressed data is selected from the set of ink cartridge characteristic data for performing an acquisition job with respect to another ink amount data based on the address information.
The beneficial effects of the above technical scheme are: the data compression storage method of the ink box chip compresses at least one set of ink box characteristic data to obtain and store an ink box characteristic data set containing at least one set of compressed data, the ink box characteristic data set is used as related operation data for recycling of the ink box, meanwhile, switching change of different compressed data can be carried out adaptively according to the current using progress state of one set of compressed data, so that the aim of recycling of the ink box data on the same chip for multiple times can be achieved, applicability of a recyclable ink box system to different occasions is improved, and using switching efficiency and reliability of the ink box of the recyclable ink box system are improved.
Preferably, in step S1, the compressing at least one set of cartridge feature data to obtain and store a cartridge feature data set including at least one set of compressed data specifically includes:
step S101, compressing data related to different state quantities of the ink box in a mode of combining a space address with data, and compressing and storing the data related to the different state quantities of the ink box to the different space addresses, wherein the data related to the different state quantities of the ink box comprises at least one of ink color data, ink model data, ink box full load data, ink box no-load data and data with the ink quantity lower than a preset threshold quantity;
step S102, compressing the ink amount data information of the ink box by adopting a mode of combining a regular data storage area and a non-regular data storage area, so as to obtain ink amount compressed data information of regular compressed data containing N1-bit storage data and non-regular compressed data containing a plurality of 1-bit storage data;
step S103, storing preset ink box starting key data, extracting and storing mutual common data of the ink boxes, and storing starting control marking bits of the ink boxes, wherein the starting control marking bits are address pointers pointing to compressed storage spaces of the ink box characteristic data sets;
and step S104, the data obtained by compression processing or storage in the steps S101, S102 and S103 are combined into the ink box characteristic data set.
Referring to fig. 2, it corresponds to a schematic compression diagram of data related to different state quantities of the ink cartridge in the data compression and storage method of the ink cartridge chip. Since the nonvolatile data storage of the ink cartridge chip is that the storage of various state quantities of the ink cartridge, which may include but not limited to at least one of ink color data, ink model data, ink cartridge full data, ink cartridge empty data, and data with an ink quantity below a preset threshold amount, needs to be considered, information corresponding to the state quantities is generally stored in different areas of a spatial address in a scattered manner, and there are often many spaces between the areas where no data is stored, which results in a waste of corresponding storage space, as shown in the left side of fig. 2, D1, D2, D3 respectively represent information corresponding to the state quantities, and x represents an address space where no data is stored. In view of the above-mentioned drawbacks, the present invention employs the combination of space addresses and data as shown in the right side of fig. 2, where a1, a2, A3 respectively represent storage space addresses, and D1, D2, D3 respectively represent state quantity data information correspondingly stored in the storage space addresses a1, a2, A3, to store, thereby effectively avoiding waste of address space.
Referring to fig. 3-4, schematic diagrams corresponding to the ink volume data of the ink cartridge in the data compression and storage method of the ink cartridge chip are shown. In order to represent the ink amount data information in the ink cartridge, the expression of the ink amount data information is generally designed to map the actual ink amount of the ink cartridge with bit data, and as can be seen from fig. 3, according to the consumption situation of the actual ink amount in the ink cartridge, the number of bits corresponding to the ink amount area in the memory is modified to record the consumption of the ink amount, since the nonvolatile memory of the printer can only perform one-way writing, that is, only 0 can be written into 1 or only 1 can be written into 0, the characteristic of the one-way writing exactly matches the characteristic of one-way change that the ink amount in the ink cartridge of the printer can only be reduced but not increased, so that the characteristic of one-way change that the ink amount can only be reduced but not increased is thoroughly ensured on the process bottom layer by using this way.
Referring to fig. 4, according to the characteristic of the unidirectional write, in an actual operation, N consecutive 1-bit data are stored, where a value of N is a natural number that is an integer power of 2, a storage area of the N is defined as a regular data storage area, each 1bit in the regular data storage area is mapped to N bits in a data space before compression, 1bit in the regular data storage area is 1, which indicates that all N corresponding bits in the data space before compression are 1, and conversely, 1bit in the regular data storage area is 0, which indicates that all N corresponding bits in the data space before compression are 0. Because the ink amount data in the data space before compression is continuous, if the condition that the tail of the data can not make up N1 bits is not considered, the information is lost only by means of the compression of the regular data storage area, so that a non-regular data storage area needs to be opened up, if the condition that the tail of the data can not make up N bits is met, the information is stored in the non-regular data storage area in a mode of combining a space address and the data, after the compression processing, the occupied space of the data is reduced, and any useful information is not lost.
In addition, the preset ink box starting key data can not be compressed continuously generally, so that the preset ink box starting key data can only be stored as it is, only one set of common data of the ink boxes needs to be stored, and the starting control mark bit of the ink box determines which set of ink box data is used specifically.
The ink cartridge feature data set shown in fig. 5 is obtained by the above-described series of compression storage operations.
Preferably, in step S1, the step of selecting one set of compressed data from the ink cartridge feature data set for performing the ink cartridge authentication and ink cartridge record acquisition includes:
step S105, according to the start control mark bit in the ink box characteristic data set, selecting a group of compressed data matched with the start control mark bit from the ink box characteristic data set, and transmitting the group of compressed data to a logic processing hardware circuit;
step S106, the logic processing hardware circuit is instructed to decompress the group of compressed data, and then the decompressed group of compressed data is utilized to execute ink box authentication and ink box record acquisition work;
step S107, in the process of executing the ink box authentication and ink box record acquisition work, determining whether the decompressed group of compressed data is modified by an instruction issued by the printer end, if so, compressing the modified group of compressed data again and storing the compressed data in the original corresponding storage space.
The beneficial effects of the above technical scheme are: because the data of the ink box characteristic data set is compressed and stored, the data cannot be directly used, the data needs to be decompressed and restored before being used, and the corresponding start control marking bit marks which set of ink box data should be used currently, so that the subsequent processing can select the corresponding ink box data for decompression.
Preferably, in step S2, the obtaining of the current usage progress status information of the one group of compressed data, and determining, according to the usage progress status information, address information corresponding to another group of compressed data obtained from the ink cartridge feature data set in the next step specifically includes:
determining whether the current one group of compressed data is used up in the process of executing the acquisition of the ink volume data, if so, modifying the start control mark bit, and then determining address information corresponding to the other group of compressed data acquired from the ink box characteristic data set in the next step according to the modified start control mark bit;
alternatively, the first and second electrodes may be,
after determining that the current group of compressed data is used up in the process of acquiring the ink volume data, detecting whether a user performs a preset type of operation action on the printer system, if so, modifying the start control mark bit, and then determining address information corresponding to another group of compressed data acquired from the ink box feature data set in the next step according to the modified start control mark bit, wherein the preset type of operation action comprises any one of an ink car warehouse-out or warehouse-in action of the printer, an ink box inserting or extracting ink car action and a printer power-off or power-on action;
alternatively, the first and second electrodes may be,
and determining whether the current residual ink amount of the ink box is lower than a preset threshold amount or not according to the ink amount data information of the ink box, if so, modifying the starting control mark bit, and then determining address information corresponding to another group of compressed data acquired from the ink box characteristic data set in the next step according to the modified starting control mark bit.
The beneficial effects of the above technical scheme are: the three different address information determining modes can ensure that the address information corresponding to another group of compressed data can be determined quickly and accurately under the condition that the corresponding printer operates to the maximum extent.
Preferably, in step S3, the step of selecting another set of compressed data from the set of ink cartridge characteristic data for performing another acquisition job with respect to another ink amount data according to the address information specifically includes:
step S301, according to the address information, selecting another group of compressed data from the ink box characteristic data set, and transmitting the another group of compressed data to a logic processing hardware circuit;
step S302, instruct the logic processing hardware circuit to decompress the other set of compressed data, and then execute acquisition work related to the other ink amount data by using the decompressed other set of compressed data.
The process of processing the other set of compressed data is the same as the process of processing the one set of compressed data, and will not be described in detail here.
