Example one
In order to solve the above problems in the prior art, an embodiment of the present invention provides a program updating method, which is implemented in a system including an updating apparatus and a consumable chip.
Specifically, please refer to fig. 1, which is an information interaction diagram of a program updating method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
s101, the updating device obtains data to be updated.
And S102, the updating equipment sends the data to be updated to the consumable chip.
And S103, the consumable chip receives the data sent by the updating device.
And S104, identifying whether the received data is the data to be updated by the consumable chip.
And S105, if the received data is identified as the data to be updated, the consumable chip writes the data to be updated into the designated address according to the updating mode of the data to be updated so as to update the designated program.
The technical scheme of the embodiment of the invention has the following beneficial effects:
in the embodiment of the invention, the updating device can send the acquired data to be updated to the consumable chip, and after the consumable chip receives the data, if the data is identified as the data to be updated, the data to be updated is written into the designated address according to the updating mode of the data to be updated so as to update the designated program; in this way, the program area in the consumable chip adopts a readable and writable memory, so that the data to be updated can be written into the designated address in the memory, and the data written into the designated address in the memory can be called by the updating device; therefore, the program in the consumable chip can be written in and read according to actual needs and is not fixed and unchangeable, and when the program in the consumable chip needs to be updated and upgraded, the program can be updated without additionally issuing a new version of the consumable chip.
Example two
The embodiment of the invention provides a program updating method, which is executed in updating equipment.
In the embodiment of the present invention, when the software portion in the consumable chip needs to be updated, the updating device executes the program updating method provided in the embodiment of the present invention.
For example, when a certain program in the consumable chip is not complete and needs to be completed, the scheme can be started. Or, for another example, a blank program segment exists in a position for storing a program in the consumable chip, and the scheme may be started when the blank program segment needs to be filled up so that the consumable chip has a certain function. Alternatively, for example, when a certain program already provided in the consumable chip needs to be changed or rewritten to change the function originally provided in the consumable chip, the scheme may be activated. Or, for another example, some special addresses exist in the level section in the consumable chip, the consumable chip can determine which programs to run according to the values stored in the special addresses, and when the values of the special addresses need to be rewritten to open the runnability of some programs, the scheme can be started.
Specifically, please refer to fig. 2, which is a flowchart illustrating a first embodiment of a program updating method according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
s201, acquiring data to be updated.
And S202, sending the data to be updated to the consumable chip.
In a specific implementation process, the data to be updated may include, but is not limited to: identifier, address information, updating mode, program code needing updating, length, check and the like.
Wherein, the identifier is used for indicating the consumable chip to execute the action of the updating program. For example, the first identifier may be used to indicate that the consumable chip directly overwrites data stored in a specified storage location in the consumable chip after receiving the identifier; alternatively, for another example, the second identifier may be used to instruct the consumable chip to run a program in the consumable chip for addressing after receiving the identifier, and then to rewrite the data stored in the addressed location.
It should be noted that the update mode in the data to be updated is associated with the address information, and the address information may be null or may not be null according to the difference of the update modes. It is understood that the address information is null, which means that the address information may not be included in the data to be updated.
For example, if the updating mode in the data to be updated is to directly utilize the address information in the data to be updated, when the updating device sends the data to be updated to the consumable chip, the address information cannot be null, so that the consumable chip can directly update the data stored at the address according to the address information in the data to be updated.
Or, for another example, if the updating manner in the data to be updated is to call an original program segment in the consumable chip, since the address is already specified in the original program segment, the address information in the data to be updated sent by the updating apparatus may be null.
Or, for another example, if the update mode in the data to be updated is addressing for the consumable chip, the address information in the data to be updated sent to the consumable chip by the update device may be null, because the consumable chip may call its own program to address, and then update the data of the address obtained by addressing.
It should be noted that, in the embodiment of the present invention, the update device may include, but is not limited to: a printer or a third party update device, such as a burner or the like, dedicated to updating the chip.
Based on this, when the update device acquires the data to be updated, there may be several specific ways:
firstly, the updating device directly generates the data to be updated in itself according to the preset information of the data to be updated. At this time, the update apparatus may be a printer or a third party update apparatus.
Specifically, if the update device is a printer, the printer directly generates and sends the data to be updated to the consumable chip, that is, the printer updates the consumable chip.
Or, if the update device is a third-party update device, the third-party update device directly generates and sends the data to be updated to the consumable chip, that is, the third-party update device updates the consumable chip.
And secondly, the updating device is a printer, the printer acquires data to be updated in the third-party updating device, and the data to be updated is generated by the third-party updating device according to preset information of the data to be updated.
At this time, the updating device is a printer, and the printer is responsible for acquiring data to be updated and sending the data to be updated to the consumable chip, that is, the printer updates the consumable chip; in this process, the third party update device is used only to generate the data to be updated.
It should be noted that, when the printer or the third-party update device generates the data to be updated, the data to be updated can be generated according to the information of the data to be updated preset by the user and the program compiling rule in the consumable chip; therefore, after the consumable chip writes the data to be updated into the designated address, the newly written data can be connected with the program codes before and after the designated address.
It should be noted that, in the embodiment of the present invention, the program compiling rule in the consumable chip is not particularly limited, for example, the program compiling rule may include but is not limited to: code formats, use of registers cannot be overridden, stacks must be balanced, etc. In the actual application process, the program compiling rule of the consumable chip can be preset in the updating device in advance.
For example, if the program in the consumable chip is a binary code compiled according to a specified rule, when the printer or the third-party updating device generates the data to be updated, the printer or the third-party updating device inevitably compiles the information of the data to be updated preset by the user according to the specified rule, so as to obtain the data to be updated according to the program compiling rule in the consumable chip.
For step S202, the embodiment of the present invention provides two implementation manners:
in the first mode, after the updating equipment acquires the data to be updated, the data to be updated is directly sent to the consumable chip without other processing.
And secondly, after the updating equipment acquires the data to be updated, the data to be updated is subjected to data processing, and the processed data to be updated is sent to the consumable chip. Among other things, data processing may include, but is not limited to: encryption, compression, format conversion, and the like, which are not particularly limited in this embodiment of the present invention.
In a specific implementation process, the updating device may encrypt data to be updated; and then, sending the encrypted data to be updated to the consumable chip, so that the safety of the data transmission process between the updating equipment and the consumable chip can be improved.
In the embodiment of the invention, when the consumable chip needs to be updated, the program updating process is executed to update the program in the consumable chip; in the embodiment of the invention, the consumable chip can further determine whether the program in the consumable chip is updated successfully.
In a specific implementation process, after the updating device sends the data to be updated to the consumable chip, the updating device can also send an operation instruction to the consumable chip, so that the consumable chip operates the specified program according to the operation instruction and returns an operation result; then, the updating equipment receives the operation result; furthermore, whether the consumable chip is updated successfully or not can be determined according to the operation result.
Specifically, the operation instruction sent by the updating device to the consumable chip is to instruct the consumable chip to call the updated programs obtained according to the newly written data. Thus, if the consumable chip can call the program, the successful operation result can be obtained, which indicates that the consumable chip is successfully updated. On the other hand, if the consumable chip cannot call the program, the running result of the running failure is obtained, and thus, the updating device can determine that the consumable chip fails to be updated, so that the consumable chip can be determined not to be updated, and then, the updating device can realize the screening of whether the consumable chip is available.
The technical scheme of the embodiment of the invention has the following beneficial effects:
in the embodiment of the invention, the updating device can send the acquired data to be updated to the consumable chip, and after the consumable chip receives the data, if the data is identified as the data to be updated, the data to be updated is written into the designated address according to the updating mode of the data to be updated so as to update the designated program; in this way, the program area in the consumable chip adopts a readable and writable memory, so that the data to be updated can be written into the designated address in the memory, and the data written into the designated address in the memory can be called by the updating device; therefore, the program in the consumable chip can be written in and read according to actual needs and is not fixed and unchangeable, and when the program in the consumable chip needs to be updated and upgraded, the program can be updated without additionally issuing a new version of the consumable chip.
EXAMPLE III
The embodiment of the invention provides a program updating method, which is executed in a consumable chip.
Specifically, please refer to fig. 3, which is a flowchart illustrating a second embodiment of the program updating method according to the embodiment of the present invention, as shown in fig. 3, the method includes the following steps:
s301, receiving data sent by the updating device.
S302, identifying whether the received data is data to be updated.
And S303, if the received data is identified as the data to be updated, writing the data to be updated into the specified address according to the updating mode of the data to be updated so as to update the specified program.
It should be noted that the update device may include, but is not limited to: printers or third party update devices that are dedicated to updating chips, e.g., burn-in instruments, etc.; the embodiment of the present invention is not particularly limited to this.
Specifically, since there is a possibility that other data may interact between the updating device and the consumable chip, after the consumable chip receives the data sent by the updating device, it needs to identify the data to determine whether the newly received data is the data to be updated. The specific implementation manner of the identification data of the consumable chip is not particularly limited in the embodiments of the present invention.
For example, the consumable chip may determine whether the received data includes the designation information, and if it is identified that the received data includes the designation information, determine that the received data is to-be-updated data; otherwise, the received data is determined not to be the data to be updated.
Specifically, if the specified information is an update mode and a program code to be updated, the consumable chip identifies whether the data contains the update mode and the program code to be updated after receiving the data sent by the update device, and if the data contains both the update mode and the program code to be updated, the consumable chip determines that the newly received data is the data to be updated; or if the data only contains one of the updating mode and the program code needing to be updated, the consumable chip determines that the newly received data is not the data to be updated; or if the data does not contain the updating mode and the program code needing to be updated, the consumable chip determines that the newly received data is not the data to be updated.
Or, for another example, the consumable chip may determine whether the received data carries the designated identifier, and if it is recognized that the received data carries the designated identifier, determine that the received data is to-be-updated; otherwise, the received data is determined not to be the data to be updated.
It can be understood that the above two examples are only used to illustrate how the consumable chip identifies whether the received data is to-be-updated data, in practical applications, the identification step may also have other implementation manners, and the embodiment of the present invention is not limited thereto.
It should be noted that the data to be updated may include, but is not limited to: identifier, address information, updating mode, program code needing updating, length, check and the like.
Wherein, the identifier is used for indicating the consumable chip to execute the action of the updating program. For example, the first identifier may be used to indicate that the consumable chip directly overwrites data stored in a specified storage location in the consumable chip after receiving the identifier; alternatively, for another example, the second identifier may be used to instruct the consumable chip to run a program in the consumable chip for addressing after receiving the identifier, and then to rewrite the data stored in the addressed location.
It should be noted that the data to be updated received by the consumable chip needs to conform to the program compiling rule of the consumable chip, so that after the data to be updated is written into the designated address, the newly written data can be connected with the program codes before and after the designated address.
The embodiment of the present invention does not particularly limit the program compiling rules in the consumable chip, for example, the program compiling rules may include but are not limited to: code formats, use of registers cannot be overridden, stacks must be balanced, etc. In the actual application process, the program compiling rule of the consumable chip can be preset in the updating device in advance.
In the embodiment of the invention, data received by the consumable chip can be encrypted, so that in a specific implementation process, the consumable chip can further identify whether the received data is encrypted data, and if the received data is identified to be encrypted data, the data needs to be decrypted. Or, if the received data is identified as non-encrypted data, no other processing is required to be performed on the received data.
It should be noted that, after receiving the data, the consumable chip may immediately perform encryption identification on the received data, and then perform the step of identifying whether the received data is to-be-updated in S202; alternatively, the consumable chip may perform encryption recognition after the step of recognizing whether the received data is to-be-updated in S202 is performed, and then perform the updating step in S203.
It should be noted that the update mode in the data to be updated is associated with the address information, and the address information may be null or may not be null according to the difference of the update modes. It is understood that the address information is null, which means that the address information may not be included in the data to be updated.
Based on the above, the embodiment of the present invention provides three specific implementation manners for the consumable chip to execute the step of updating the program in S203:
first, when the update mode is the first mode, the data to be updated is written into the address indicated by the address information.
The first method is to directly use the address information in the data to be updated to update the program, and at this time, the address information in the data to be updated cannot be empty. Therefore, when the program of the consumable chip is updated, the data to be updated is directly written into the address indicated in the address information.
It should be noted that the information stored in the memory of the consumable chip by the address indicated in the address information carried in the data to be updated may be null. That is, the address indicated by the address information is a blank program segment in the consumable chip; at this time, the program to be updated is written into the address, that is, the consumable chip has the function of writing the program newly, or the operability of some programs can be opened.
Or, the information stored in the memory of the consumable chip by the address indicated in the address information carried in the data to be updated may also be non-empty. That is, in the memory of the consumable chip, other programs have been stored in the address indicated by this address information; at this time, the program to be updated is written into the address, that is, the existing program in the consumable chip is changed or rewritten, so that the original function in the consumable chip can be changed, or the original function in the consumable chip can be perfected.
And secondly, when the updating mode is the second mode, writing the data to be updated into the address specified by the specified program.
The second way is to call a designated program in the consumable chip, and at this time, because the address is already designated in the designated program, the address information in the data to be updated can be null. Therefore, when the program of the consumable chip is updated, the data to be updated only needs to be written into the address specified by the specified program.
It should be noted that, when the method is used to implement program update, the information stored in the address pointed by the designated program may not be empty, and at this time, the data to be updated is written into the designated address of the designated program, so that the original function of the consumable chip may be changed, or the original function of the consumable chip may be improved.
Thirdly, when the updating mode is the third mode, calculating to obtain an address according to the data to be updated, and writing the data to be updated into the calculated address.
The third updating mode is to call the program in the consumable chip for addressing.
At this time, the address information in the data to be updated may be empty,
when the updating mode is adopted, the consumable chip can perform data processing on the data to be updated by using a designated program or algorithm to obtain a target address, and the data to be updated is written into the target address.
Alternatively, the address information in the data to be updated may not be empty.
When the updating mode is adopted, the consumable chip can perform data processing on the address information in the data to be updated by using a designated program or algorithm to obtain a target address, and write the data to be updated into the target address.
When the program update is realized by using this method, the consumable chip itself stores the program for addressing. And moreover, the self program can be called for addressing, and the data of the address obtained by addressing is updated. The address obtained by addressing with the program may be non-empty, or the address may also be empty, which is not particularly limited in this embodiment of the present invention.
It should be noted that, after the consumable chip writes the programs to be updated into the designated address, the consumable chip may further respond to the operation instruction sent by the updating device to call the newly written programs and obtain the operation result. The consumable chip can return the operation result to the updating device, so that the updating device can determine whether the program updating process of the consumable chip is successful according to the operation result, and further realize whether the consumable chip is available for screening by the updating device.
In a specific implementation process, the consumable chip can receive an operation instruction sent by the updating device; then, operating the specified program according to the operating instruction to obtain an operating result; and finally, returning the operation result to the updating equipment. It can be understood that the designated program is a program obtained by updating the consumable chip according to the data to be updated, and the program may be a rewriting or perfecting of an original program, or may be a new program having a new function.
It should be noted that, the embodiment of the present invention provides a program updating method implemented in a consumable chip, and the consumable chip may be located in an imaging cartridge. In a specific implementation, the imaging cartridge may be an ink cartridge.
The technical scheme of the embodiment of the invention has the following beneficial effects:
in the embodiment of the invention, the updating device can send the acquired data to be updated to the consumable chip, and after the consumable chip receives the data, if the data is identified as the data to be updated, the data to be updated is written into the designated address according to the updating mode of the data to be updated so as to update the designated program; in this way, the program area in the consumable chip adopts a readable and writable memory, so that the data to be updated can be written into the designated address in the memory, and the data written into the designated address in the memory can be called by the updating device; therefore, the program in the consumable chip can be written in and read according to actual needs and is not fixed and unchangeable, and when the program in the consumable chip needs to be updated and upgraded, the program can be updated without additionally issuing a new version of the consumable chip.
