[ detailed description ] embodiments

For better understanding of the technical solutions of the present application, the following detailed descriptions of the embodiments of the present application are provided with reference to the accompanying drawings.

It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Image forming apparatuses such as printers, copiers, etc. are equipped with consumable cartridges (e.g., ink cartridges, toner cartridges, etc.). The consumable cartridge may be detachably mounted to the image forming apparatus. The consumable box comprises a body, and a consumable chip is arranged on the body. The consumable chip may be detachably mounted on the consumable cartridge body.

The embodiment of the present application can provide a consumable chip, which is used for executing the authentication data switching method provided by the embodiment of the present application, so as to realize active switching of authentication data, without being limited and influenced by instructions of external devices such as an imaging device.

Fig. 1 is a schematic structural diagram of a consumable chip according to an embodiment of the present disclosure. As shown in fig. 1, a consumable chip 10 provided in the embodiment of the present application may include: a control module 101, a battery module 102, and a battery monitoring module 103.

The battery module 102 may supply power to the battery monitoring module 103 when the consumable chip 10 does not supply power to an external device such as an imaging device. The battery module 102 may be a button battery, a capacitor, a lithium battery, or the like with a small volume. In other embodiments, the battery module 102 may also be connected to the consumable chip 10 by wires, and need not be disposed on the consumable chip 10.

The battery monitoring module 103 may be configured to monitor the power of the battery module 102, so as to obtain power data of the battery module 102. In some embodiments, the battery monitoring module 103 may be a coulometer and use advanced fuel metering algorithms to accurately measure the remaining capacity of the battery module 102. In another embodiment, the battery monitoring module 103 for monitoring the power level may be integrated into the control module, and the consumable chip 10 does not need to have a separate battery monitoring module 103.

The control module 101 may be configured to switch the authentication data according to the power data of the battery module 102. In one mode, the control module 101 may obtain the power data monitored by the battery monitoring module 103, and control the authentication data switching process according to the power data. Memory circuitry may be included in the control module 101. At least two different sets of authentication data, such as first authentication data and second authentication data, may be stored in the memory circuit. The switching of the authentication data may be switching from the first authentication data currently selected to be output to the outside to output the second authentication data, or switching from the second authentication data currently selected to be output to the outside to output the first authentication data. Meanwhile, the control module 101 may also be used to control communication between the consumable chip 10 and the imaging device. The control module 101 may be a single chip, a microcontroller, a Field Programmable Gate Array (FPGA), a logic circuit, or the like.

The consumable chip 10 may further include a circuit board (not shown in fig. 1). The circuit board may carry the control module 101, the battery module 102, and the battery monitoring module 103. In one possible implementation, the control module 101 and the battery monitoring module 103 may be integrated in the same circuit. The circuit may be designed as an integrated circuit, embodied in a wafer. In this implementation, the consumable chip 10 includes the wafer and a circuit board for carrying the wafer.

Fig. 2 is a flowchart of an authentication data switching method according to an embodiment of the present application. As shown in fig. 2, the authentication data switching method may include:

step 101, a control module acquires electric quantity data of a battery module.

And step 102, after the control module determines that the electric quantity data meets the authentication data switching condition, switching the currently output authentication data.

After the consumable chip is produced, the battery modules arranged on the consumable chip start to discharge. Specifically, a fixed current discharge mode, for example, a discharge by a current of 1mA, may be adopted. And the natural discharge can be carried out through water vapor, dust and the like in the air. In the case of natural discharge, the discharge current is less than 1mA, typically in the microampere level, and at this time, a battery module with a smaller capacity can be configured, thereby saving the cost.

In one possible implementation, the battery monitoring module may start monitoring the power data of the battery module after receiving the power supply of the battery module.

In another possible implementation manner, the battery monitoring module may start monitoring the electric quantity data of the battery module in response to the received first monitoring instruction. The first monitoring command may be automatically triggered after the consumable chip is shipped from a factory, or may be automatically triggered after the consumable chip is sold. This is not limited by the present application.

In the embodiment of the application, the battery monitoring module does not receive the influence of external imaging equipment to the electric quantity monitoring of battery module, namely, whether the consumptive material box has been installed on imaging equipment, all can carry out electric quantity data monitoring to battery module.

After the consumable cartridge is installed in the imaging device, the consumable chip is in contact with the contact pin of the imaging device, so that the imaging device can supply power to the consumable chip through the contact pin after being powered on. After the consumable chip is powered on, the initialization operation can be automatically executed.

In this embodiment of the application, the trigger condition for the control module to acquire the electric quantity data of the battery module may be, for example: in response to the above power-on initialization (i.e., the imaging device supplies power to the consumable chip), or receiving a reset signal (a level rising curve of a clock or a data signal line, a number of clocks, etc.) sent by the imaging device, or receiving a preset instruction (e.g., an instruction to read authentication data), etc., the present application is not limited, and only needs to be performed before the consumable chip sends the authentication data or the imaging device reads the authentication data.

Specifically, when acquiring the electric quantity data, in one possible implementation, the control module may acquire the electric quantity data from the battery monitoring module. Based on the natural discharge or the passive discharge of the battery module, the control module can switch the currently output authentication data after the electric quantity data of the battery module meets the authentication data switching condition.

Specifically, multiple sets of authentication data can be preset in the consumable chip. The authentication data may be, for example, one or more of a chip serial number, a toner serial number, an ink serial number, a digital signature, seed data, or verification data. Data associated therewith, such as production date information, etc., may also be included. This is not limited by the present application. The consumable chip can designate any one of the multiple sets of authentication data as default authentication data in factory settings, namely currently output authentication data.

Furthermore, under the condition that a plurality of sets of authentication data are set in the consumable chip, a plurality of set thresholds can be set. Each set threshold may be mapped with each authentication data. The control module may determine that the electric quantity data meets the authentication data switching condition, that is, the remaining electric quantity is lower than a set threshold, and at this time, the currently output authentication data may be switched. Specifically, when the remaining power in the battery module is lower than a first set threshold, the control module may switch the currently output authentication data to the first authentication data; when the remaining power in the battery module is lower than the second set threshold, the control module may switch the currently output authentication data to the second authentication data, and so on, which is not described in detail.

The remaining power can be replaced by any data which can represent the battery power using condition, such as power consumption and the like, and the data is not limited in the application.

Through the technical scheme, the consumable chip can realize the active switching of the authentication data without being limited and influenced by instructions of external equipment such as imaging equipment, so that the reliability of authentication data switching is improved, and the authentication success rate is improved.

In another embodiment of the present application, the method for switching the authentication data is further described.

Fig. 3 is a flowchart of another authentication data switching method according to an embodiment of the present application. As shown in fig. 3, the authentication data switching method may include:

in step 201, the control module obtains a voltage value of the battery module.

In step 202, the control module determines that the voltage value is smaller than the nth voltage threshold and larger than the (N + 1) th voltage threshold, and switches the currently output authentication data into nth authentication data.

In the field of battery correlation, there is a correspondence between the open circuit voltage of a battery and the remaining capacity of the battery.

For convenience of understanding, the embodiment of the present application provides a corresponding relationship between the open-circuit voltage and the remaining capacity of the lithium battery as shown in table 1:

voltage of battery	Electric quantity of battery	Voltage of battery	Electric quantity of battery	Voltage of battery	Electric quantity of battery
						4.20V	100％	3.87V	60％	3.74V	20％
4.06V	90％	3.82V	50％	3.68V	10％
						3.98V	80％	3.79V	40％	3.45V	5％
3.92V	70％	3.77V	30％	3.20V	0％

TABLE 1

It should be noted that table 1 is only an exemplary illustration and is not a limitation to the embodiments of the present application.

Because the corresponding relationship exists, in the embodiment of the application, the battery monitoring module can acquire the electric quantity data of the battery module by monitoring the voltage value of the battery module.

Specifically, the battery detection module may perform voltage monitoring on the battery module according to a set period to obtain a voltage value of the battery module. The value of the setting period can be set according to the requirement, for example, 1 hour.

In the embodiment of the application, at least one voltage threshold value can be set in the control module of the consumable chip.

In a possible implementation manner, the consumable chip sets a first authentication data in addition to the default authentication data, and sets a first voltage threshold. In this implementation, the control module may switch the currently output authentication data to the first authentication data when determining that the acquired voltage value is smaller than the first voltage threshold. Through the implementation mode, the consumable chip can execute one-time switching on the currently output authentication data.

In one possible implementation, the consumable chip sets a plurality of authentication data in addition to the default authentication data, and sets a plurality of voltage thresholds. In this implementation, the control module may switch the currently output authentication data to the first authentication data when determining that the acquired voltage value is smaller than the first voltage threshold and larger than the second voltage threshold. And when the acquired voltage value is judged to be smaller than the second voltage threshold and larger than the third voltage threshold, switching the currently output authentication data into second authentication data. So on, it will not be described in detail. Through the implementation mode, the consumable chip can execute multiple times of switching on the currently output authentication data.

Fig. 4 is a flowchart of another authentication data handover method according to an embodiment of the present application. As shown in fig. 4, the authentication data switching method may include:

in step 301, the control module obtains the discharge duration of the battery module.

Step 302, the control module determines that the discharge time length is greater than the nth time length threshold and less than the (N + 1) th time length threshold, and switches the currently output authentication data into nth authentication data.

In the embodiment of the application, because the residual capacity of the battery module is related to the discharge current value and the discharge duration, on the basis of the stability of the discharge current value of the battery module, the battery monitoring module can monitor the discharge duration of the battery module, and the electric quantity data of the battery module is acquired by monitoring the discharge duration.

For convenience of understanding, a lithium battery will be described as an example.

Assuming that the capacity of the battery module is 1000 milliamp-hours (mAh), the battery module is discharged through a resistance of 4.2k ohms, and the discharge current is 4.2V/4.2k ═ 1 mA. Then, the total dischargeable time of the battery module is 1000 hours. When the battery monitoring module monitors that the discharge time reaches 100 hours, the remaining power can be considered as (1000 + 100)/1000-90%.

Based on the above description, the battery detection module may time the discharge time of the battery module. In an exemplary implementation, the timing may be implemented by way of counting. The battery monitoring module may be a Real Time Clock (RTC).

For example, if a crystal oscillator RTC is used, such as RTC-4553, SD2000, DS1388, etc., the crystal frequency is 32.768 kHz. Therefore, when the count value of the RTC reaches 32768, it indicates that the count value is 1 second. In an integrated circuit, the battery monitoring module may employ an internal oscillator, such as an RC oscillator, a programmable oscillator, or the like.

In this embodiment of the application, the discharge duration output by the battery monitoring module may be a count value of the RTC, or may be a timing value obtained by performing mathematical conversion according to the count value. This is not limited by the present application.

In the embodiment of the application, at least one time length threshold value can be set in the control module of the consumable chip. It should be noted that, if the discharge time period output by the battery monitoring module is a count value, the time period threshold here is a count threshold.

In one possible implementation, a duration threshold, such as a first duration threshold, may be set in the control module. The control module can switch the currently output authentication data into first authentication data when judging that the obtained discharge time is greater than the first time threshold. In this implementation, the control module can only switch the authentication data once.

In another possible implementation manner, a plurality of duration thresholds, such as a first duration threshold, a second duration threshold, and a third duration threshold, may be set in the control module. The control module can switch the currently output authentication data into first authentication data when judging that the obtained discharge time is greater than the first time threshold and less than the second time threshold. And switching the currently output authentication data into second authentication data when the obtained discharge time is judged to be greater than the second time threshold and less than the third time threshold. So on, it will not be described in detail.

In this implementation, the control module may switch the currently output authentication data multiple times.

It should be noted that the time interval between the time threshold values may be the same or different. Illustratively, to facilitate timely switching of authentication data, the time interval between the time thresholds may be sequentially decreased.

In another possible implementation, a duration threshold, such as the first duration threshold, may be set in the control module. When the control module determines that the obtained discharge time reaches a first time threshold and switches the currently output authentication data into the first authentication data, the battery monitoring module can clear the monitored discharge time. The battery monitoring module may then re-time the discharge duration. When the discharge duration reaches the first duration threshold again, the control module may switch the currently output authentication data to the second authentication data. So on, it will not be described in detail. Through the implementation mode, the control module can realize multiple times of switching of multiple authentication data under the condition of only storing one duration threshold.

Further, in another embodiment of the present application, the control module may simultaneously obtain the voltage value and the discharge time period of the battery module from the battery monitoring module in response to an authentication request of the imaging device. Furthermore, the control module can judge the voltage value and the discharge time length at the same time.

Specifically, when the control module determines that the discharge time length is greater than the nth time length threshold and less than the (N + 1) th time length threshold, and the voltage value is less than the nth voltage threshold and greater than the (N + 1) th voltage threshold, the currently output authentication data may be switched to the nth authentication data.

Fig. 5 is a flowchart of another authentication data switching method according to an embodiment of the present application. As shown in fig. 5, the authentication data switching method provided in the embodiment of the present application includes the following steps:

step 401, the control module obtains the electric quantity status identifier of the battery module.

Step 402, the control module determines that the electric quantity state identification is consistent with the Nth setting identification, and switches the currently output authentication data into the Nth authentication data.

In the embodiment of the application, at least one voltage threshold and/or duration threshold corresponding to the authentication data can be stored in the battery monitoring module of the consumable chip.

In the process of monitoring the discharge time and/or the voltage value of the battery module, the battery monitoring module can set the electric quantity state identifier to be consistent with the Nth set identifier after determining that the discharge time is longer than the Nth time threshold and is smaller than the (N + 1) th time threshold and/or the voltage value is smaller than the Nth voltage threshold and is larger than the (N + 1) th voltage threshold. The nth setting flag may be used to indicate the current remaining power, and the specific form may be set by a protocol between the control module and the battery monitoring module.

After the control module acquires the electric quantity state identification from the battery monitoring module, the electric quantity state identification can be compared with each preset identification of a pre-protocol. And judging that the electric quantity state identification is consistent with the Nth set identification, and switching the currently output authentication data into the Nth authentication data by the control module.

For ease of understanding, one example is illustrated.

The electric quantity data monitored by the battery monitoring module is assumed to be discharge time, and a first time threshold is stored in the battery monitoring module. Then, when the battery monitoring module monitors that the discharge duration reaches the first duration threshold, the current electric quantity state identifier may be set to be consistent with the first setting identifier. Illustratively, the first setting flag may be, for example, 1, FF, or the like. Conversely, if the battery monitoring module monitors that the discharge duration does not reach the first duration threshold, the current state of charge identifier may be maintained. For example, the current state of charge indicator may be 0, 00, etc.

The battery monitoring module may then output the state of charge indication to the control module. The control module confirms that the electric quantity state identification is consistent with the first set identification, and if the electric quantity state identification is 1, the currently output authentication data can be switched into the first authentication data.

Based on the implementation manner of the embodiment of the application, the voltage threshold and/or the duration threshold do not need to be stored in the control module.

Fig. 6 is a flowchart of another authentication data switching method according to an embodiment of the present application. As shown in fig. 6, after the step 102, the authentication data switching method provided in the embodiment of the present application further includes the following steps:

and 103, the control module sends the switched authentication data to the imaging equipment for authentication.

Step 104, the control module detects whether the authentication is successful. If the authentication is successful, executing step 105; otherwise, step 101 is continued.

And 105, controlling the battery monitoring module to stop monitoring the battery module by the control module.

In this embodiment, after the authentication data sent by the control module to the image forming apparatus is successfully authenticated, the image forming apparatus may start to perform a printing operation. At this time, the control module may control the battery monitoring module to stop monitoring the battery module. Specifically, the battery monitoring module may no longer monitor the voltage value of the battery module, or stop timing the discharge time (for example, clearing the RTC). Meanwhile, the control module can stop acquiring the monitored electric quantity data of the battery monitoring module, stop switching new authentication data and lock the authentication data in the currently selected state. In particular, the control module may set flag information (e.g., stored in the memory circuit) on the program or logic control, which may be used to record that the authentication data has been locked in the currently selected state.

Accordingly, if the authentication data transmitted to the image forming apparatus is failed to be authenticated, the control module may re-perform step 101, re-acquire the power data when the trigger condition for acquiring the power data of the battery module is satisfied again, and switch the output authentication data again according to the re-acquired power data.

Specifically, when the user determines that the authentication fails according to the display screen of the imaging device, the consumable box can be taken out of the imaging device, and the consumable box is kept stand for a preset time until the electric quantity data of the battery module in the consumable chip meets the authentication data switching condition again. Then, the consumable cartridge may be reinstalled into the image forming apparatus to trigger the step 101 of acquiring the triggering condition of the charge amount data of the battery module.

Or when the user determines that the authentication fails according to the display screen of the imaging device, the consumable box can be kept in the imaging device for a preset time period until the electric quantity data of the battery module in the consumable chip meets the authentication data switching condition again. Then, the imaging device may be powered on again to trigger the trigger condition of acquiring the power data of the battery module in step 101.

In another embodiment of the present application, the structure and function of the consumable chip are further described.

In the embodiment of the present application, as shown in fig. 1, the consumable chip 10 includes a control module 101 and a battery module 102.

The control module 101 is configured to obtain power data of the battery module 102. And the switching module is also used for switching the currently output authentication data after the electric quantity data is determined to meet the authentication data switching condition.

In a specific implementation manner, the consumable chip 10 further includes a battery monitoring module 103, configured to monitor the battery module 102 to obtain the electric quantity data. The control module 101 is specifically configured to obtain the electric quantity data of the battery module 102 from the battery monitoring module 103.

In a specific implementation, the electric quantity data includes a discharge time length and/or a voltage value. The battery monitoring module 103 is specifically configured to time the discharge time of the battery module 102 to obtain the discharge duration of the battery module 102; and/or detecting the voltage of the battery module 102 according to a set period to obtain the voltage value of the battery module 102.

In a specific implementation, the power data includes a power status identifier. The battery monitoring module 103 is specifically configured to determine that the discharge time is longer than the nth time threshold and shorter than the (N + 1) th time threshold, and/or that the voltage value is shorter than the nth voltage threshold and longer than the (N + 1) th voltage threshold, and set the electric quantity state identifier to be consistent with the nth setting identifier.

In a specific implementation manner, the control module 101 is specifically configured to determine that the electric quantity status identifier is consistent with the nth setting identifier, and switch the currently output authentication data into nth authentication data, where N is a positive integer.
