All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a flow chart of a data compression storage method of an ink cartridge chip according to an embodiment of the invention is shown. The data compression 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 to execute ink box authentication and ink box record acquisition work;
Step S2, acquiring the current use progress status information of one group of compressed data, and 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 use progress status information;
and step S3, selecting another group of compressed data from the characteristic data set of the ink cartridge according to the address information for executing the acquisition work of the other ink quantity data.
The beneficial effects of the technical scheme are as follows: the data compression storage method of the ink box chip is used for 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, the ink box characteristic data set is used as associated operation data for recycling the ink box, meanwhile, switching and changing of different compressed data can be adaptively carried out according to the current use progress state of one set of compressed data, so that the aim of recycling the ink box data for multiple times can be achieved by carrying out regeneration of the ink box data for multiple times on the same chip, and therefore the applicability of a recyclable ink box system to different occasions is improved, and the ink box use switching efficiency and reliability of the recyclable ink box system are improved.
Preferably, in the step S1, compressing at least one set of ink cartridge feature data to obtain and store an ink cartridge feature data set including at least one set of compressed data specifically includes:
step S101, compressing data of different state quantities of the ink box by adopting a mode of combining space addresses with data, so as to compress and store the data of the different state quantities of the ink box onto different space addresses, wherein the data of the different state quantities comprise at least one of ink color data, ink model data, ink box full-load data, ink box no-load data and ink quantity data lower than a preset threshold value;
step S102, compressing ink volume data information of the ink box in a mode of combining a regular data storage area and a non-regular data storage area to obtain ink volume 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 commonality 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 characteristic data sets of the ink boxes;
Step S104, the data obtained by compression processing or storage in the steps S101, S102 and S103 are combined into the characteristic data set of the ink cartridge.
Referring to fig. 2, a schematic diagram of data compression of different state quantities of the ink cartridge in the data compression storage method of the ink cartridge chip is shown. Since the nonvolatile data storage of the ink cartridge chip is that of the storage of various state quantities of the ink cartridge, which may include, but are not limited to, at least one of ink color data, ink model data, ink cartridge full data, ink cartridge empty data, and ink quantity below a preset threshold quantity, the information corresponding to the state quantities is generally stored in different areas of the space address in a scattered manner, and there is often a lot of space between these areas where no data is stored, which may lead to waste of the corresponding storage space, as shown in the left side of fig. 2, D1, D2, D3 respectively represent the information corresponding to the state quantities, and x represents the address space where no data is stored. In order to overcome the above drawbacks, the present invention uses a combination of a spatial address and data as shown on the right side of fig. 2 to store, so as to effectively avoid the waste of address space, 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.
Referring to fig. 3-4, schematic diagrams are formed corresponding to ink volume data of the ink cartridge in the data compression storage method of the ink cartridge chip. In order to represent the ink volume data information in the ink cartridge, the expression mode of the ink volume data information is generally designed to map the actual ink volume of the ink cartridge with bit data, and as can be seen from fig. 3, the number of bits corresponding to the ink volume area in the memory is modified according to the consumption condition of the actual ink volume in the ink cartridge, so that the consumption of the ink volume is recorded, and the non-volatile memory of the printer can only write one way, namely can only write 0 into 1 or can only write 1 into 0, and the one-way writing characteristic exactly matches the one-way changing characteristic that the ink volume in the ink cartridge of the printer can only be reduced but not increased, so that the one-way changing characteristic that the ink volume can only be reduced but not increased can be thoroughly ensured on the bottom layer of the process in this way.
Referring to fig. 4, according to the above-mentioned unidirectional writing characteristic, in actual operation, continuous N1 bit data are stored, where N is a natural number to the integer power of 2, the storage area may be defined as a regular data storage area, each 1bit in the regular data storage area is mapped to N bits in the data space before compression, 1bit in the regular data storage area is 1, which indicates that all the N bits corresponding to the N bits in the data space before compression are 1, and otherwise, 1bit in the regular data storage area is 0, which indicates that all the N bits corresponding to the N bits in the data space before compression are 0. Because the ink volume data in the data space before compression is continuous, if the situation that N1 bits cannot be obtained at the end of the data is not considered, the information is lost only by means of the compression of the regular data storage area, therefore, an irregular data storage area needs to be opened up, if any situation that N bits cannot be obtained is met, the information is stored in the irregular data storage area in a mode of combining space addresses with the data, after the compression processing, the occupied space of the data is reduced, and no useful information is lost.
In addition, the preset ink cartridge start key data cannot be compressed continuously, so that the preset ink cartridge start key data can only be stored as it is, only one set of common data of the ink cartridges needs to be stored, and the start control mark bit of the ink cartridge determines which set of ink cartridge data is specifically used.
The set of cartridge characteristic data shown in fig. 5 can be obtained through the above-described series of compressed storage operations.
Preferably, in the step S1, selecting one of the compressed data from the set of ink cartridge characteristic data for performing ink cartridge authentication and ink cartridge record acquisition specifically includes:
step S105, selecting a group of compressed data matched with the start control mark bit from the ink box characteristic data set according to the start control mark bit in 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 used for executing ink box authentication and ink box record acquisition;
step S107, in the process of executing the ink cartridge authentication and ink cartridge record acquisition work, determining whether the decompressed group of compressed data is modified by the instruction issued by the printer end, if so, re-compressing the modified group of compressed data and storing the modified group of compressed data in the original corresponding storage space.
The beneficial effects of the technical scheme are as follows: because the data of the ink cartridge characteristic data set is stored in a compressed mode and cannot be directly used, the data of the ink cartridge characteristic data set needs to be decompressed and restored before being used, and the corresponding start control mark bit marks which ink cartridge data set should be used currently, so that the corresponding ink cartridge data can be selected for decompression in subsequent processing.
Preferably, in the step S2, obtaining the current usage progress status information of the one set of compressed data, and determining, according to the usage progress status information, address information corresponding to another set of compressed data obtained from the feature data set of the ink cartridge in the next step specifically includes:
determining whether the current compressed data of one group is used in the process of executing the ink quantity data acquisition work, if yes, modifying the start control mark bit, and determining address information corresponding to the other compressed data of the other group acquired from the ink box characteristic data set according to the modified start control mark bit;
or alternatively, the process may be performed,
when it is determined that the current compressed data of one group is used in the process of executing the ink quantity data acquisition, detecting whether a user performs a preset type of operation action on the printer system, if yes, modifying the start control mark bit, and determining address information corresponding to another group of compressed data acquired from the ink box characteristic data set according to the modified start control mark bit, wherein the preset type of operation action comprises any one of a printer ink vehicle unloading or loading action, an ink box inserting or extracting action and a printer power-off or power-on action;
Or alternatively, the process may be performed,
and determining whether the current residual ink quantity of the ink box is lower than a preset threshold value according to the ink quantity data information of the ink box, if so, modifying the start control mark bit, and determining address information corresponding to another group of compressed data acquired from the characteristic data set of the ink box in the next step according to the modified start control mark bit.
The beneficial effects of the technical scheme are as follows: the three different address information determining modes can ensure that the address information corresponding to the other group of compressed data can be determined rapidly and accurately under the corresponding printer operation condition to the greatest extent.
Preferably, in the step S3, selecting another group of compressed data from the set of ink cartridge characteristic data for performing an acquisition job on another ink amount data based on the address information specifically includes:
step S301, selecting another group of compressed data from the ink box characteristic data set according to the address information, and transmitting the another group of compressed data to a logic processing hardware circuit;
in step S302, the logic processing hardware circuit is instructed to decompress the other set of compressed data, and then execute the acquiring operation on the other ink volume 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 is not described here.
