[0001] This application belongs to the field of printer technology, and in particular relates to a communication authentication method, a regeneration chip, and regeneration consumables. Background Technology

[0002] In the printing industry, there are many consumables on the market (such as ink cartridges, toner cartridges, drum units, etc.). Some manufacturers recycle consumables and attach recycled chips to the original chips of the consumables, thus enabling the consumables to be recycled.

[0003] However, regenerated consumables require communication authentication before they can execute printing commands normally. Currently, the industry urgently needs a method for communication authentication. Summary of the Invention

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0011] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, "and / or" in this application indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship. It should be noted that all data involved in this application was obtained with the user's authorization.

[0012] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0013] Figure 1This is a flowchart illustrating a communication authentication method according to one embodiment of this application. Figure 1 As shown, the communication authentication method of this application embodiment may specifically include the following steps: S101 receives a communication authentication command sent by the printer. The communication authentication command includes the response time required by the serial data line.

[0014] In this embodiment of the application, the execution subject of the communication authentication method is a regenerated chip attached to the original chip of the original consumable (e.g., original ink cartridge, original toner cartridge, original drum unit, etc.). Figure 2 As shown, the regenerator chip 21 is connected to the printer 22 and the original chip 23 in the original consumable 25 via a serial clock line (SCL) and a serial data line (SDA), respectively. The communication protocol can be I2C, and the regenerator chip 21 can be soldered to the original chip 23. Specifically, the printer 22 provides a clock signal to the regenerator chip 21 via the clock line, a data signal via the data line, and a power signal and a ground signal via the power line and ground line (GND), respectively. Furthermore, when the regenerator chip 21 needs to communicate with the original chip 23—in other words, when the original chip 23 needs to participate in the communication—the regenerator chip 21 actively generates a clock signal, a power signal, and a ground signal and sends them to the original chip 23, while simultaneously generating / forwarding a data signal and sending it to the original chip 23 for communication. That is, the original chip 23 can establish communication with the printer 22 through the regenerator chip 21, but does not communicate directly with the printer 22.

[0015] The regeneration chip receives communication authentication commands sent by the printer. These commands may include, but are not limited to, the required response time for the serial data line. Specifically, the communication authentication command can be a pull-low command, a pull-high followed by a pull-low command, or a pull-low followed by a pull-high command, etc., and the corresponding required response time may include the time required for both the pull-high and / or pull-low actions. The printer can send these communication authentication commands to the regeneration chip via the serial data line between the printer and the regeneration chip.

[0016] The communication authentication command may include, but is not limited to, the 1C command. The format of the 1C command can be simplified as follows: 1C XXXX, where 1C is the command and XX XX indicates the time during which the serial data line connected to the chip needs to be pulled low.

[0017] S102 forwards the communication authentication command to the original chip, so that the original chip can adjust the voltage on the first serial data line between the regenerated chip and the original chip to the set voltage within the required response time according to the communication authentication command.

[0018] In this embodiment, the regenerated chip forwards the received communication authentication command to the original chip. Upon receiving the command, the original chip performs a corresponding adjustment operation. Specifically, the original chip adjusts the voltage on the first serial data line (i.e., the first SDA) between the regenerated chip and the original chip to a set voltage within the required response time. Taking a low-voltage operation as an example, the set voltage is typically 0 volts, but can also be other preset values; this embodiment does not impose any limitations.

[0019] S103, detect the voltage on the first serial data line and send the voltage on the first serial data line to the printer.

[0020] In this embodiment, the regenerated chip detects the voltage on the first serial data line (i.e., the serial data line status of the original chip) in real time and sends the voltage on the first serial data line to the printer.

[0021] Furthermore, since the original chip may be damaged or the communication line between the original chip and the remanufactured chip may be damaged, the above step S102 "forwarding the communication authentication command to the original chip" may specifically include the following steps: detecting whether the communication between the original chip and the remanufactured chip is normal; if the communication is normal, then forwarding the communication authentication command to the original chip.

[0022] Specifically, the regenerated chip detects whether the original chip and the regenerated chip can communicate normally. If the original chip and the regenerated chip can communicate normally, the regenerated chip will forward the received communication authentication command to the original chip.

[0023] The regenerated chip can detect whether communication between the original chip and the regenerated chip is normal through the following steps: the regenerated chip sends a handshake request to the original chip; if a handshake response is detected from the original chip within a set time, it is determined that communication between the original chip and the regenerated chip is normal; if no handshake response is detected from the original chip within the set time, it is determined that communication between the original chip and the regenerated chip is abnormal. The value range of the set time can be 1 to 200 milliseconds (ms), and this embodiment does not impose a limitation. For example, the set time can be within 20ms after receiving the communication authentication command.

[0024] Furthermore, the communication authentication method in this application embodiment may also include the following steps: if communication is abnormal, then according to the communication authentication command, the voltage on the second serial data line between the regeneration chip and the printer is adjusted to a set voltage within the required response time.

[0025] Specifically, if the original chip and the recycled chip cannot communicate normally, the recycled chip will handle the communication authentication command itself, that is, the recycled chip will perform the corresponding adjustment operation itself. Specifically, the recycled chip will adjust the voltage on the second serial data line (i.e. the second SDA) between the recycled chip and the printer to the set voltage within the required response time.

[0026] It should be noted that in this embodiment, the original chip is given priority in responding to communication authentication commands, with the recycled chip serving as a supplement, which further improves communication reliability.

[0027] Furthermore, the recycled chip or the original chip adjusts the voltage to the set voltage within the required response time, which may specifically include the following steps: adjusting the voltage to the set voltage at different frequencies within the required response time; or adjusting the voltage to the set voltage at a set frequency within the required response time.

[0028] Specifically, taking the pull-low operation as an example, when a recycled chip or original chip performs a pull-low operation, it can maintain the voltage on the serial data line at a set voltage for the required pull-low time, or it can control the voltage on the serial data line to a square wave of different frequencies for the required pull-low time, or it can control the voltage on the serial data line to a square wave of a set frequency for the required pull-low time. This set frequency can be carried in the communication authentication command sent by the printer, or it can be preset in the recycled chip or original chip.

[0029] Furthermore, after the required response time, the regenerated chip or the original chip can restore the voltage on the serial data line to the default value (i.e., the value before adjustment, generally 3.3 volts, which is not limited in this embodiment) to ensure normal operation thereafter.

[0030] Specifically, the printer can send a recovery command to the regeneration chip after the required response time, and the regeneration chip or original chip can then perform a voltage recovery operation based on this command. Alternatively, the regeneration chip or original chip can perform the voltage recovery operation itself after the required response time.

[0031] To clearly illustrate the communication authentication method of this application embodiment, the following is combined with... Figure 3 The overall process of the communication authentication method according to the embodiments of this application is described in detail. For example... Figure 3 As shown, taking the pull-low operation as an example, the communication authentication method of this application embodiment may specifically include the following steps: S501, the regeneration chip receives the IC command sent by the printer, the IC command includes the time when SDA needs to be pulled low.

[0032] S502, the regenerated chip sends a handshake request to the original chip.

[0033] S503: Does the regenerated chip detect a handshake response from the original chip within the set time? If yes, proceed to step S504. If no, proceed to step S506.

[0034] S504, the regenerated chip forwards the communication authentication command to the original chip, and the original chip pulls down the voltage on the first SDA between the regenerated chip and the original chip to the set voltage within the required time.

[0035] S505, the regeneration chip detects the voltage on the first serial SDA and sends the voltage on the first SDA to the printer.

[0036] S506, the regeneration chip pulls the voltage on the second SDA between the regeneration chip and the printer down to the set voltage within the required time.

[0037] The S507, regenerator chip and native chip restore voltage to default value after the required pull-down time.

[0038] In summary, the communication authentication method of this application embodiment involves the regenerator chip forwarding the communication authentication command sent by the printer to the original chip. The original chip, based on the communication authentication command, adjusts the voltage on the first serial data line between the regenerator chip and the original chip to a set voltage within the required response time. The regenerator chip then sends the detected voltage on the first serial data line to the printer, thus achieving communication authentication between the regenerator chip and the original chip. Furthermore, the original chip is given priority in responding to the communication authentication command, with the regenerator chip serving as a supplement, further improving communication reliability.

[0039] This application also provides a regenerable chip. For example... Figure 4 As shown, the regeneration chip 21 in this embodiment of the application may specifically include: a receiving module 61, a forwarding module 62, and a detection module 63. Wherein: The receiving module 61 is used to receive the communication authentication command sent by the printer. The communication authentication command includes the response time required by the serial data line.

[0040] The forwarding module 62 is used to forward the communication authentication command to the original chip, so that the original chip can adjust the voltage on the first serial data line between the regenerated chip and the original chip to the set voltage within the required response time according to the communication authentication command.

[0041] The detection module 63 is used to detect the voltage on the first serial data line in real time and trigger the forwarding module 62 to send the voltage on the first serial data line to the printer.

[0042] In one feasible implementation of this application, the regenerated chip 21 may further include: a processing module; the detection module 63 is specifically used to: detect whether the communication between the original chip and the regenerated chip is normal; if the communication is normal, trigger the forwarding module 62 to forward the communication authentication command to the original chip; if the communication is abnormal, trigger the processing module to adjust the voltage on the second serial data line between the regenerated chip and the printer to a set voltage within the required response time according to the communication authentication command.

[0044] In this embodiment, the regenerator chip forwards the communication authentication command sent by the printer to the original chip. Based on the communication authentication command, the original chip adjusts the voltage on the first serial data line between the regenerator chip and the original chip to a set voltage within the required response time. The regenerator chip then sends the detected voltage on the first serial data line to the printer, thus achieving communication authentication between the regenerator chip and the original chip. Furthermore, the original chip prioritizes responding to the communication authentication command, with the regenerator chip acting as a supplement, further improving communication reliability.

[0045] This application also provides a recyclable consumable. For example...

The regenerator chip sends the detected voltage on the first serial data line to the printer, realizing the communication authentication between the regenerator chip and the original chip. The original chip takes priority in responding to the communication authentication command, and the regenerator chip, as a supplement, further improves the communication reliability.

[0047] This application also provides a communication authentication system. For example... Figure 2 As shown, the communication authentication system includes a printer 22 and recyclable consumables 24 as described in the above embodiment.
