The invention will be further described below in conjunction with drawings and Examples.
The specific embodiment
Referring to Fig. 2, Fig. 2 is the structural representation of the general consumable chip embodiment of the present invention.The general consumable chip 10 of present embodiment comprises a substrate 20, and substrate 20 is provided with microcontroller 11 and five contacts 21 that are connected with microcontroller 11.After the consumable container that general consumable chip 10 is installed was installed on the color printer, microcontroller 11 just was connected with data/address bus by contact 21, thereby carries out communication with color printer.When needing to upgrade the communication data of general consumable chip 10 storages, simultaneously be installed in color printer with the consumable container that a certain chip is installed the consumable container that general consumable chip 10 is installed, so-called certain chip is meant the chip that stores the communication data that has upgraded.Like this, general consumable chip 10 and certain chip be common data bus just, and be just identical with the data/address bus connected mode with as shown in Figure 1 a plurality of consumable container chips.
Referring to Fig. 3, Fig. 3 is the schematic block diagram of each functional module of microcontroller among the general consumable chip embodiment of the present invention.In the present embodiment, microcontroller 11 comprises a memory block 15, and memory block 15 comprises known communication data field 12, upgrades communication data district 13 and communication data updating flag bit 14.Wherein, known communication data field 12 stores known communication command and corresponding output result, communication command that these are known and corresponding output result are that compatible consumable container production firm writes when general consumable chip is made, and are communication command and output result that compatible consumable container production firm is known.One do not store the blank memory space of any data and upgrade communication data district 13, when general consumable chip views when the communication data that has upgraded is arranged between certain chip and the color printer, just the communication data that upgrades is saved in and upgrades in the communication data district 13, just after general consumable chip is preserved communication data, upgrade just storing new communication command and corresponding output result in the communication data district 13.Communication data updating flag bit 14 stores a updating mark, and this updating mark writes in general consumable chip manufacturing process, and uses the back to be removed by microcontroller 11 for the first time at general consumable chip, so updating mark only is to use once.In the present embodiment, updating mark is binary number " 1 ", represents that general consumable chip is in the communication data updating state.After updating mark was eliminated, the data of communication data updating flag bit 14 storages became binary number " 0 ", and general consumable chip just enters normal read-write state.
A plurality of consumable container chip of the present invention and data/address bus connected mode are same as the prior art, just with shown in Figure 1 identical, wherein at least one is the certain chip that stores the communication data that has upgraded in four chips, and at least one is general consumable chip.After four consumable containers are all installed and opening color printer, color printer is just started working, and the workflow diagram of general consumable chip as shown in Figure 4.
After color printer was started working, to each chip power supply, general consumable chip obtained to start working behind the electric energy by data/address bus.At first, general consumable chip judges whether the communication data updating flag bit stores updating mark (step S1).Because updating mark writes in general consumable chip manufacturing process, when general consumable chip just during task, general consumable chip can determine the communication data updating flag bit and store updating mark, i.e. binary number " 1 ".At this moment, general consumable chip is just checked the communication command (step S6) that color printer sends to certain chip.Because certain chip stores communication command and the output result who has upgraded, therefore can allow color printer identification.Then, general consumable chip judges whether color printer is new communication command (step S7) to the communication command that certain chip sends, if new communication command, then this communication command is saved in and upgrades in the communication data district, and check the output result that certain chip is returned to color printer, should export the result simultaneously and also be saved in the renewal communication data district (step S10), and this communication command was mapped with the output result, form a new communication data.Judging color printer when general consumable chip is not new communication command to the communication command that certain chip sends, judge further then whether certain chip is new output result (step S8) to the output result that color printer sends, if new output result, then should export the result and be saved in and upgrade in the communication data district (step S9), and will this new output result be mapped with corresponding communication command.If general consumable chip judges that this output result is not new output result, the communication of then judging color printer and certain chip whether finish (step S11), if finish, then remove the updating mark (step S12) of communication data updating flag bit, just the data with the storage of communication data updating flag bit change binary number " 0 " into by binary number " 1 ".If do not finish, then return step S6, check the communication command that color printer sends to certain chip once more.
Since general consumable chip just during task communication data do not upgrade, when carrying out communication, color printer and general consumable chip can't obtain correct output result, the color printer cisco unity malfunction, but general consumable chip is preserved new communication data get off in this course.When restarting color printer, general consumable chip just can use the communication data and the color printer that have upgraded to carry out communication.
After color printer restarts, provide power supply to general consumable chip once more, after the general consumable chip work, judge once more whether the communication data updating flag bit stores updating mark (step S1).Because this moment, updating mark was eliminated, therefore general consumable chip judges that the communication data updating flag bit does not store updating mark, just receive the communication command (step S2) that color printer sends, and analyze the content (step S3) of this communication command, then in the known communication data field with upgrade in the communication data district and search the output result of this communication command correspondence, and should export the result and sent to (step S4) in the color printer.Like this, color printer just can receive correct output result, thinks that general consumable chip can carry out correct communication with color printer, but just operate as normal of color printer.At last, general consumable chip can judge whether that also the communication command that receives color printer finishes (step S5), if finish, then finishes communication work, if do not finish, then returns step S2, receives the communication command that color printer sends once more.
By above-mentioned scheme as seen, owing in general consumable chip, increase by a communication data updating flag bit and upgrade the communication data district, general consumable chip can be checked the communication data between color printer and the certain chip when first task, and new communication data is kept in the renewal communication data district.Make the communication data of automatic renewal of general consumable chip and color printer like this, when general consumable chip is worked once more, just can use the communication data and the color printer communication of renewal, guarantee the communication between general consumable chip and the color printer, make the color printer can operate as normal.
Certainly, general consumable chip provided by the invention not only can be the chip of consumable containers such as print cartridge, cartridge, the general consumable chip in other field, as the communication chip of various compatible equipments and main equipment in the telecommunications field etc., also can utilize general consumable chip of the present invention and communication data updating method with communication data updating.
It is emphasized that at last to the invention is not restricted to above-mentioned embodiment, for example updating mark can be set at " 0 ", is binary number " 1 " and will remove what store on the communication data updating flag bit after the updating mark; Or upgrade the communication data district and be not arranged in the microcontroller, and be arranged on memory device microcontroller outside or the like, conspicuous equivalence variation like that also should be included in the protection domain of claim of the present invention.
