It should be noted that, the following embodiments of the present invention may be implemented separately or in combination with each other, and the embodiments of the present invention are not limited thereto.

Example 1

Fig. 1 is a flowchart of a data processing method of a consumable device chip for a printer according to a first embodiment of the present invention, as shown in fig. 1, where the data processing method of a consumable device chip for a printer according to the embodiment of the present invention may include:

step S102, verifying the received writing request, wherein the writing request is used for requesting the operation of writing target data;

the execution subject of the above steps may be a consumable device chip for consumable device information storage. The consumable device is used for installing and using consumable materials and providing the consumable materials for a printer to use according to printing instructions of the connected printer. For the printer, the consumable device may be a ribbon, a cartridge, an ink cartridge, a toner, or the like. The consumable device chip can be installed on printers of different models, and performs operations such as data storage, verification and the like on consumable devices required by the printers of the models.

If the write data is written successively a plurality of times, the verification may be performed each time, and the verification may be performed in the same manner or may be performed differently. The specific verification method may be that the verification is performed while the write data is transmitted, or may be that the verification is performed before the write data is written. Of course, only one verification may be performed, and after the one verification is passed, writing is completed according to the writing requirement until the writing is completed.

The target data may be used to identify the consumable of the consumable type, for example, the target data may be a consumable code table to identify the coding of the consumable. The target data may also include other writable data, for example, the configuration information.

Optionally, verifying the received write request includes: receiving a writing request, and acquiring a login key in the writing request; decrypting and verifying the login key to verify the write-in request; under the condition that the decrypted login key is successfully verified, the verification of the writing request is confirmed to pass.

The login key may be generated by the writing device, and the writing device may generate the login key according to the information to be verified. The information to be verified may include information of the device identification of the writing device, the account and password of the writing operation, the account authority of the writing operation, and the like.

And the consumable equipment receives the login key and then decrypts the login key to obtain information to be verified, and verifies the information, and under the condition that the information passes verification, the writing request can be confirmed to pass verification. At this point, the information requiring verification is verified, and the writing request can be considered to be safe.

Optionally, in the case that the write request passes verification, before performing the write operation of the target data in response to the write request, the method further includes: in the case that the write request passes the verification, transmitting a message passing the verification to the write device; the writing device is used for sending a writing request, and under the condition that the writing device receives the message, the writing device sends data to be written to a sender of the message, namely a consumable device chip; or writing the target data under the condition that the verification of the writing request is passed, wherein the target data and the writing request are transmitted by the writing device together, and after the target data and the writing request are received, caching the target data.

And under the condition that the verification of the writing request is passed, sending a message passing the verification to the writing device, namely, only the writing request sent by the writing device for the first time, wherein the consumable device chip firstly verifies the writing request, and after the verification is passed, feeding back the message passing the verification to the writing device, and the writing device sends written target data in response to the message passing the verification. Through a feedback mode, the writing device is informed of passing verification, the writing target data is not required to be cached, and the occupation of chip resources is reduced.

And the write-in equipment packages and sends the write-in request and the written target data together, and after receiving the write-in request and the target data, the consumable equipment chip caches the target data and verifies the write-in request, so that the target data which needs to be written in can be directly read from the cache to be directly written in under the condition that the verification is passed. The method for caching the target data avoids data interaction, realizes faster writing speed and improves the writing speed of the target data.

Step S104, when the verification of the writing request is passed, responding to the writing request to perform writing operation of the target data; if the verification passes, the write request may be deemed secure, or the corresponding write operation and target data may be secured. Writing can be performed according to the normal writing procedure.

Optionally, performing the data write operation in response to the write request includes: receiving data of a writing operation through a preset communication port; determining whether the writing operation is accurately transmitted or not by detecting information of the data of the communication port; and in the case that the writing operation is accurate in transmission, responding to the writing operation, and writing corresponding data.

The consumable device chip may be provided in plurality, so that the corresponding relationship between the writing data and the consumable device chip is involved. The verification of the writing request can verify not only the writing device, but also whether the writing operation corresponds to the consumable device chip. The accuracy of the mapping relation between the written data and the consumable device chip is ensured. And further ensures the use and compatible accuracy of consumable equipment chips.

For example, there are 10 consumable device chips, and 5 consumable device chips are expected to be compatible with the first consumable device chip and the second consumable device chip, and data x can be written into positions storing control switching information in the nonvolatile memories of the 5 consumable device chips 0-4, that is, the written data x corresponds to the 5 consumable device chips 0-4, where the written data x is used to characterize the working circuit of the first consumable device chip. And writing data y into the positions of the nonvolatile memories of the other 5 consumable device chips 5-9, wherein the positions store the control switching information, namely the writing data y and the 5 consumable device chips 5-9 correspond to each other, and the writing data y is used for representing the working circuit of the consumable device chip II. The data x selects the switching dissimilar circuit B, the data y selects the switching dissimilar circuit C, and the data x and the same circuit A are combined into a complete chip circuit.

After receiving the writing data, judging whether the writing data is the writing data x or the writing data y, and according to the corresponding relation, sending the writing data x to the 5 consumable device chips 0-4 and sending the writing data y to the 5 consumable device chips 5-9. Therefore, after the chip is electrified, 5 consumable device chips 0-4 can read the storage control switching information in the memory and then select the different circuits, write data x and select the switching different circuits B, and after the chip is electrified and then read the storage control switching information in the memory, other 5 consumable device chips 5-9 can select the different circuits, write data y and select the switching different circuits C, and the different circuits C and the same circuits A are combined into a complete chip circuit, so that compatibility of the consumable device chip I or the consumable device chip II is realized.

If the write request is not verified, the write process is ended.

Step S106, acquiring a configuration signal in the target data, wherein the configuration signal is used for determining the consumable type of the printer which needs to be compatible;

it should be noted that, the printer has a plurality of types and a plurality of corresponding consumable types, and in order to realize compatibility of a plurality of consumable types, the embodiment configures the corresponding working mode through the configuration signal to realize compatibility of a plurality of consumable types, so as to improve usability of consumable equipment or consumable equipment chips, increase application range, and improve competitiveness of products.

The configuration information corresponds to the consumable type, and thus, in implementation, the configuration information may be an identifier of a different consumable type, for example, a number, an ID, or the like.

Optionally, before acquiring the pre-stored configuration signal, the method further includes: receiving a configuration signal written by a writing device, wherein the writing device is a device for sending a writing request; the configuration signal is written to a non-volatile storage medium.

The writing device is used for writing data into the consumable device or the consumable device chip, and the writing device can comprise a communication unit used for transmitting data between the writing device and the consumable device. The communication unit may be a wired communication unit or a wireless communication unit. The kind of specific communication unit depends on the way of communication between the writing device and the consumable device.

The writing of the consumable device chip is usually performed through a wireless mode, if parallel writing of data to a plurality of consumable device chips is needed, although wireless communication can be performed through using a plurality of communication coils or using different frequency bands, reliability and stability are not stable and efficient like wired communication, the problem of vulnerability is solved, and the communication distance is limited by the distance between the writing device and the consumable material. Therefore, in this embodiment, a wired communication manner is preferred, and data is transmitted between the writing device and the consumable device. The communication unit may be a wired communication unit.

In this embodiment, the communication between the writing device and the consumable device may be through wired CLK clock lines and DATA lines. The writing device controls the nonvolatile memory of the consumable device by controlling the CLK clock line and the DATA DATA line and writes DATA identifying IDs of different consumable types, and the consumable device can select switching compatible with different consumable types by loading the ID DATA after power-on starting. The function that a plurality of printers can be commonly used on one consumable device chip by only one piece is realized, the production cost of products is greatly reduced, the use mode is flexible and convenient, and the competitiveness of the products is increased.

In this embodiment, the non-volatile memory is preferably selected to avoid loss of the stored configuration signal due to power failure of the consumable device, and the non-volatile memory is not affected by power failure of the consumable device. The internal configuration signal can be maintained after the consumable device is powered down, so that the configuration signal can be directly read when the consumable device is powered up, the corresponding consumable type can be determined, and work preparation can be performed.

On this basis, acquiring the pre-stored configuration signal comprises: the configuration signal is read from the non-volatile storage medium. The configuration signal is used for representing the working circuit of the corresponding consumable device chip.

Step S108, selecting a corresponding working circuit according to the configuration signal to switch to a corresponding working mode, wherein the working mode is matched with the consumable type of the printer.

The configuration signal corresponds to the consumable type, and thus, the corresponding consumable type can be determined according to the configuration signal. However, the working circuits of different consumable types are different, and in order to achieve compatibility of multiple consumable types, the working circuits of multiple consumable types need to be accommodated. However, the working circuits generally comprise hardware and are required to be arranged during manufacturing, but all the working circuits with various consumable types are assembled together, so that the circuit is complex, error is easy to occur, and the manufacturing cost is high.

For this reason, the present embodiment compares the working circuits of the various consumable types, uses the same circuit portion as the same circuit, and uses different circuit portions as the different circuits, that is, the unique circuits corresponding to each consumable type. Then, when in manufacture, the same circuit is only required to be provided with one, the different circuits of each consumable type are respectively provided, the different circuits corresponding to the consumable types which need to be provided can be selected through one switch circuit, and the different circuits are combined with the same circuit to form the working circuit corresponding to the consumable type. The area of the PCB can be reduced, the cost is reduced, and the PCB is compatible with various consumable types to the greatest extent.

The above-mentioned operation mode may be understood as a mode in which the operation is performed by the operation circuit, and is matched with the consumable type corresponding to the operation circuit.

Optionally, selecting a corresponding operating circuit according to the configuration signal to switch the operating mode includes: controlling the switching logic circuit according to the configuration signal, and selecting a different circuit corresponding to the configuration signal; combining the different circuits with the same preset circuit, and determining a working circuit of a working mode corresponding to the configuration signal so as to switch to the working mode; the same circuit is the same part of circuits in the working circuits of the multiple working modes corresponding to the multiple configuration signals.

For example, the same circuit a, a different circuit B and a different circuit C exist in two consumable device chips, the first consumable device chip is composed of the circuit a and the circuit B, the second consumable device chip is composed of the circuit a and the circuit C, and the circuit B and the circuit C are different. The selector is a switching circuit in the consumable device chip, the control signal value of the selector is stored in a certain position in the consumable device chip, and the configuration signal value of the memory is loaded and read when the consumable device chip is electrified and initialized each time by controlling the selection circuit B or the circuit C to ensure compatibility of the consumable device chip I or the consumable device chip II. Because the memory inside the consumable device chip is a non-volatile memory, the internal configuration signals can be maintained after power is lost.

It should be noted that, when the consumable device chip selects the working circuit, the working circuit may be selected by some other means besides the selector, that is, the selection circuit, for example, a switch circuit. For example, the connection sequence or connection mode of different circuit parts is changed, and the working range of different components is changed, so that the whole circuit effect is changed, and the purpose of switching the working circuit is achieved.

The different configuration signals are used for selecting one of different circuits with different consumable types and connecting the different circuits with the control switching logic circuit, and particularly selecting which consumable is specifically selected through an external writing control instruction so as to realize the switching of different consumable types, and after the consumable information needing to be written is confirmed, the control switching logic circuit is used for combining the corresponding different circuits with the same circuit of the different consumable to form a working circuit of the complete consumable equipment chip.

In addition, the consumable device also includes a communication unit. The consumable device is provided with a wireless interface circuit module and a wired interface circuit module, and can be compatible with normal communication on-line printing functions of a wireless printer and a wired printer. The specific implementation mode mainly includes that a wireless interface circuit and a wired interface circuit are arranged inside a consumable device chip, but a part of the consumable device chip is packaged into a wireless contact and a part of the consumable device chip is packaged into a wired contact in the packaging process of the consumable device chip, and the fact that only the wireless contact or the wired contact exists in a printer compatible at present is considered, and the printer with both the wired contact and the wireless contact does not exist, so that the area of a PCB is reduced, and the cost is reduced.

The consumable device and the wireless printer are in communication with each other through a single coil, and other modes such as double-coil communication can be adopted, but the single coil is simple in structure and capable of meeting the requirements, so that the single coil communication is preferably adopted in the embodiment. And the power supply and the data are synthesized in one coil for wireless transmission, so that the antenna unit is simpler and the cost is lower. The consumable device and the wired printer are communicated with each other mainly through connection of two metal contact points of the consumable device and two metal contact points of the wired printer for data transmission. It is not excluded to provide a consumable device chip that can communicate both wirelessly and by wire. The communication mode between the specific consumable ink cartridge and the printer is not limited in this embodiment.

It should be noted that, the above writing device may repeatedly erase and write the control switching information of the writing data in the memory, if the consumable device chip of the 5 consumable device chips 5-9 compatible with the consumable device chip two in the past is to be changed into the consumable device chip one compatible with the consumable device chip two, only the 5 consumable device chips 5-9 are required to be written with the data x, and the 5 consumable device chips 5-9 will read the newly changed control switching information after being powered on again, thereby realizing the compatibility of the consumable device chip one.

Optionally, after writing the corresponding data, the method further includes: and sending a command for successfully receiving the writing operation to the writing device, wherein after the writing device receives the command, sending data subsequent to the writing operation, or ending the writing flow under the condition that no data is subsequent to the writing operation.

When the data is written continuously for a plurality of times, a command for successful writing is sent to the writing device after each data writing is completed, the writing device continues writing according to the command, and the writing flow is ended when no subsequent writing operation is performed.
