In this embodiment, the first detecting unit may include a sensor, and is configured to detect first environment data of a cavity environment of the image forming apparatus in real time, and send the first environment data to the chip control unit, where the cavity environment refers to an environment of an internal space surrounded by a housing of the image forming apparatus, and specifically, the first detecting unit may be a temperature sensor and/or a humidity sensor. Accordingly, the first environmental data includes temperature data and/or humidity data.

Step 202, the second detection unit detects second environmental data of the current environment of the consumable chip.

In this embodiment, the second detection unit may include a sensor, and is configured to monitor second environmental data of a current environment where the consumable chip is located in real time, and send the second environmental data to the image formation control unit. The first environment data and the second environment data are data at the same time, wherein the current environment refers to an environment of an internal space surrounded by a shell of the image forming apparatus, and the consumable is installed in the internal space. Accordingly, the second environmental data includes temperature data and/or humidity data.

Step 203, the chip control unit determines a preset compensation value of the imaging control high-voltage parameter corresponding to the second environmental data and a second preset conversion intermediate parameter corresponding to the second environmental data, performs conversion processing on the preset compensation value according to a first conversion algorithm based on the second preset conversion intermediate parameter to obtain a conversion parameter corresponding to the preset compensation value, and sends the conversion parameter to the image forming device.

Among them, the image formation control high voltage parameter is a parameter for controlling image formation of the image forming apparatus, including but not limited to a charging voltage, a transfer voltage, and a developing voltage. Accordingly, the compensation value corresponding to the imaging control high-voltage parameter may be a compensation parameter corresponding to the imaging control high-voltage parameter matching the environmental data, or may be a calibration parameter in a color image forming method, and the like, which is not limited herein.

In the above chip control unit, in the process of determining the preset compensation value of the imaging control high-voltage parameter corresponding to the second environmental data and the second preset conversion intermediate parameter corresponding to the second environmental data, the chip control unit may specifically determine the preset compensation value based on the second environmental data and the corresponding relationship between the stored environmental data and the compensation value corresponding to the imaging control high-voltage parameter, and then determine the second preset conversion intermediate parameter based on the second environmental data and the corresponding relationship between the stored environmental data and the conversion intermediate parameter.

The corresponding relation between the environmental data and the compensation value corresponding to the imaging control high-voltage parameter and the corresponding relation between the environmental data and the conversion intermediate parameter are preset and stored in the consumable chip, specifically, the environmental data and the conversion intermediate parameter can be stored in a storage unit of the consumable chip, or can be directly stored in a computer program contained in a chip control unit, and the limitation is not performed here.

It is to be understood that the corresponding relationship between the environmental data and the conversion intermediate parameter is preset and stored in the image forming apparatus, and specifically may be stored in a storage unit of the image forming apparatus, or may be directly stored in a computer program included in the image forming control unit, which is not limited herein.

Wherein the correspondence between the environmental data and the conversion intermediate parameter is stored in advance in the image forming apparatus, which is identical to the aforementioned correspondence between the environmental data and the conversion intermediate parameter stored in the chip control unit.

Specifically, the first environmental data as before includes first temperature data and first humidity data; when determining the first preset conversion intermediate parameter, the image formation control unit may first determine a temperature conversion intermediate parameter corresponding to the first temperature data based on the first temperature data and a correspondence between the stored environment data and the conversion intermediate parameter, and then determine a humidity conversion intermediate parameter corresponding to the first humidity data based on the first humidity data and a correspondence between the stored environment data and the conversion intermediate parameter. The image forming control unit performs conversion processing according to a preset second conversion algorithm based on the temperature conversion intermediate parameter, the humidity conversion intermediate parameter and the conversion parameter to obtain a preset compensation value.

Certainly, in the above process, in order to avoid the influence on the conversion intermediate parameter caused by the measurement error between the first environment data of the cavity environment of the image forming apparatus and the second environment data of the environment where the consumable chip is currently located, when the image forming control unit determines the conversion intermediate parameter, the environment data range where the first environment data is located is adaptively determined, and then the first preset conversion intermediate parameter is determined according to each environment data in the environment data range, so as to avoid the influence caused by the measurement error in this way.

Specifically, the image formation control unit determines a current environment code value according to a correspondence between the stored environment data and the conversion intermediate parameter based on the first environment data; determining other environment coding values adjacent to the current environment coding value, thereby obtaining a plurality of coding combinations consisting of the current environment coding value and the other environment coding values; selecting any one code from the multiple code organizations as the first conversion intermediate parameter, performing conversion processing on the conversion parameter according to a preset second conversion algorithm based on the first preset conversion intermediate parameter, and determining whether the preset compensation value is obtained; if not, selecting the next coding combination from the multiple coding combinations as a first preset conversion intermediate parameter, and performing conversion processing on the conversion parameter according to a preset second conversion algorithm until the preset compensation value is obtained or processing of performing a second conversion algorithm on the conversion parameter by using all the coding combinations is completed.

The other environment code values adjacent to the current environment code value may be a plurality of environment code values adjacent to the current environment code value, that is, a plurality of environment code values adjacent to the current environment code value, in which the correspondence between the stored environment data and the conversion intermediate parameter is stored.

Specifically, when the first environment data includes first temperature data and first humidity data, the image formation control unit determines a current temperature code value matching the first temperature data and a current humidity code value matching the first humidity data, respectively, according to a correspondence between the stored environment data and the conversion intermediate parameter based on the first environment data.

In addition, in this embodiment, the first preset conversion intermediate parameter is a decryption key, the second conversion algorithm is a decryption algorithm, and the image formation control unit receives a conversion parameter corresponding to the preset compensation value, that is, the encrypted preset compensation value, and then decrypts the conversion parameter based on the first preset conversion intermediate parameter through the second conversion algorithm to obtain the preset compensation value. The preset imaging control high-voltage parameter can be set according to the performance parameters of the image forming device and the performance parameters of consumables.

The image forming control method provided in this embodiment includes detecting first environment data of a printer side by a first detecting unit, detecting second environment data of a chip side by a second detecting unit, enabling a chip control unit to encrypt a preset compensation value of an imaging control high-voltage parameter corresponding to the second environment data according to a first conversion algorithm based on a second preset conversion intermediate parameter corresponding to the second environment data to obtain a conversion parameter corresponding to the preset compensation value, and sending the conversion parameter to an image forming control unit, decrypting the conversion parameter according to a second conversion algorithm based on a first preset conversion intermediate parameter corresponding to the first environment data after receiving the conversion parameter by the image forming control unit to obtain the preset compensation value, and determining a target imaging control parameter according to the preset compensation value and the preset imaging control high-voltage parameter, the encryption and decryption processing based on the environmental data can be carried out on the preset compensation value, the preset compensation value is prevented from being intercepted and falsified in the transmission process, the data transmission is safer, and the printing and imaging quality is further ensured.

Meanwhile, in order to ensure that the preset compensation value can be obtained in time, optionally, whether the second detection unit is abnormal may be determined based on the first environmental data and the second environmental data, and specifically, before step 203, the image forming control method may further include:

the chip control unit sends the second environment data to the image forming device; the image forming apparatus determines whether to perform image formation using consumables based on the second environment data and first environment data of an environment in which the image forming apparatus is currently located.

The image formation control method provided by the embodiment can timely judge whether the second detection unit is abnormal, namely timely judge whether the sensor at the chip side is abnormal, thereby avoiding the problem of printing failure caused by incapability of timely acquiring the preset compensation value corresponding to the imaging control high-voltage parameter; moreover, when the sensor on the chip side is abnormal, it may not be possible to determine in real time whether the storage state of the printing substance such as toner stored in the consumable material is good, and thus there may be a problem that the quality of the image formed by printing using the consumable material is not good even if the storage state of the printing substance is not good.

In addition, in an alternative embodiment, after receiving the conversion parameter corresponding to the preset compensation value of the imaging control high-voltage parameter sent by the consumable chip, the image forming apparatus (also referred to as the printer side) may fail to obtain the preset compensation value after decryption processing, and this may be considered as a case where a detection unit for detecting environmental data of the image forming apparatus or the consumable chip may malfunction, and in this case, an alarm may be given to the above situation.

That is, if the conversion processing is performed according to the preset second conversion algorithm based on the first preset conversion intermediate parameter and the conversion parameter, and the preset compensation value is not obtained, the method may further include: and sending alarm information of the abnormity of the consumable chip.

In this embodiment, if the image formation control unit does not obtain the preset compensation value after decryption, then the consumable chip is abnormal, and the image formation control unit generates an alarm information instruction for controlling the alarm device to send an alarm prompt indicating that the consumable chip is abnormal, or displays a prompt message on a display unit of the image formation device.

Step 302, the image forming control unit sends a data preparation instruction to the chip control unit, the chip control unit performs data preparation on the chip side after receiving the data preparation instruction, and sends a status instruction in the data preparation to the image forming control unit, and the image forming control unit performs data preparation on the printer side after receiving the status instruction in the data preparation.

In this embodiment, after the chip control unit receives the data preparation instruction, the data preparation on the chip side is performed. The second detection unit detects second environment data of an environment in which the consumable chip is currently located, the second environment data includes second temperature data and second humidity data, and correspondingly, the second detection unit may include a second temperature sensor and a second humidity sensor.

Specifically, after the chip control unit receives the data preparation instruction, the second temperature sensor detects second temperature data of the current environment where the consumable chip is located, and the second humidity sensor detects second humidity data of the current environment where the consumable chip is located.

When the image forming control unit receives a state instruction in data preparation, data preparation of the printer side is carried out, and the first detection unit detects first environment data of the cavity environment of the image forming device.

Further, after receiving a status instruction in data preparation, the image formation control unit sends an inquiry instruction to the chip control unit, where the inquiry instruction may be an instruction for inquiring a chip data preparation status.

Step 303, the chip control unit determines a preset compensation value of the imaging control high-voltage parameter based on the second environmental data and the corresponding relationship between the stored environmental data and the compensation value corresponding to the imaging control high-voltage parameter.

In this embodiment, the correspondence between the second environmental data and the compensation value corresponding to the stored environmental data and the imaging control high-pressure parameter is a two-dimensional array relationship, i.e., X and Y are input, and a unique output Z can be obtained.

Specifically, the chip control unit determines a preset compensation value based on the second temperature data, the second humidity data and the corresponding relationship between the stored environmental data and the compensation value corresponding to the imaging control high-voltage parameter, that is, determines the preset compensation value of the imaging control high-voltage parameter according to the second temperature data and the second humidity data.

Step 304, the chip control unit determines a second preset conversion intermediate parameter based on the second environment data and the corresponding relationship between the stored environment data and the conversion intermediate parameter.

Specifically, the chip control unit determines a temperature conversion intermediate parameter corresponding to the second temperature data, that is, a current second temperature code value matching the second temperature data, based on the second temperature data and the correspondence between the stored environment data and the conversion intermediate parameter, and determines a humidity conversion intermediate parameter corresponding to the second humidity data, that is, a current second humidity code value matching the second humidity data, based on the second humidity data and the correspondence between the stored environment data and the conversion intermediate parameter.

Furthermore, an encoding combination can be formed according to the current second temperature encoding value and the current second humidity encoding value, so that the second preset conversion intermediate parameter is determined.

And the chip control unit carries out conversion processing on the preset compensation value according to a first conversion algorithm based on the second preset conversion intermediate parameter so as to obtain a conversion parameter corresponding to the preset compensation value. After the conversion parameter corresponding to the preset compensation value is obtained, the chip control unit controls the chip data preparation state to be in a data preparation ready state.

Further, after inquiring that the chip data preparation state is the data ready state, the image forming control unit sends a data reading instruction to the chip control unit, and after receiving the data reading instruction, the chip control unit sends the conversion parameter to the image forming control unit.

Step 305, the image formation control unit determines a first preset conversion intermediate parameter based on the first environment data and the correspondence between the stored environment data and the conversion intermediate parameter.

In this embodiment, the first environment data includes first temperature data and first humidity data, and correspondingly, the first detection unit may include a first temperature sensor and a first humidity sensor.

Specifically, the image formation control unit determines a temperature conversion intermediate parameter corresponding to the first temperature data, that is, a current temperature code value matching the first temperature data, based on the first temperature data and the correspondence between the stored environment data and the conversion intermediate parameter, and determines a humidity conversion intermediate parameter corresponding to the first humidity data, that is, a current humidity code value matching the first humidity data, based on the first humidity data and the correspondence between the stored environment data and the conversion intermediate parameter.

Furthermore, an encoding combination can be formed according to the current first temperature encoding value and the current first humidity encoding value, so that the first preset conversion intermediate parameter is determined.

Step 306, the image forming control unit performs conversion processing according to a preset second conversion algorithm based on the first preset conversion intermediate parameter and the conversion parameter to obtain a preset compensation value, and determines a target imaging control parameter meeting a preset imaging condition according to the preset algorithm based on the preset compensation value and the preset imaging control high-voltage parameter.

For example, table 1 is a temperature range table in the correspondence between the environmental data and the conversion intermediate parameters provided herein; table 2 is a table of humidity ranges in the correspondence between the environmental data and the conversion intermediate parameters provided in the present application.

TABLE 1

TABLE 2

On the consumable chip side, the second environment data of the current environment of the consumable chip detected by the second detection unit for chip detection includes 30 degrees of second temperature data and 20 percent of second humidity data, and then the current temperature code value 0x0019 can be determined according to table 1 and the second environment data, and the current humidity code value 0xFD00 can be determined according to the second environment data and table 2, so as to determine the current humidity code value and the current temperature code value, and thus determine the second conversion intermediate parameter.

The printer side determines the first conversion intermediate parameter in the same manner as the chip side determines the second conversion intermediate parameter, and details thereof are not repeated.

Thus, the chip control unit generates the conversion parameter according to a preset algorithm based on the determined second conversion intermediate parameter and the preset compensation value of the imaging control parameter, and transmits the conversion parameter to the printer, and the printer generates the preset compensation value according to the preset algorithm based on the determined first conversion intermediate parameter and the conversion parameter, thereby determining the target imaging control parameter.

In the above method for determining the target imaging control parameter, the second conversion intermediate parameter corresponding to the consumable chip side and the first conversion intermediate parameter corresponding to the printer side correspond to each other, so as to avoid the influence on the conversion intermediate parameter due to the measurement error between the first environment data of the cavity environment of the image forming apparatus and the second environment data of the environment where the consumable chip is currently located, when the image forming control unit determines the conversion intermediate parameter, the environment data range where the first environment data is located is adaptively determined, and then the first preset conversion intermediate parameter is determined by trying according to each environment data in the environment data range, so as to avoid the influence due to the measurement error in such a manner.

For example, a previous temperature encoding value and a next temperature encoding value adjacent to the current temperature encoding value are determined according to the current temperature encoding value, and a previous humidity encoding value and a next humidity encoding value adjacent to the current humidity encoding value are determined according to the current humidity encoding value. And determining to obtain a plurality of coding combinations consisting of any temperature coding value and any humidity coding value according to the current temperature coding value, the previous temperature coding value and the next temperature coding value as well as the current humidity coding value, the previous humidity coding value and the next humidity coding value.

For example, as shown in tables 1 and 2, the current temperature code value, the previous temperature code value, and the next temperature code value are 0x0010, 0x0011, and 0x0012, respectively, and the current humidity code value, the previous humidity code value, and the next humidity code value are 0xFA00, 0xFB00, and 0xFC00, respectively, so that the obtained various code combinations may include: 0x00100xFA00, 0x00100xFB00, 0x00100xFC00, 0x00110xFA00, 0x00110xFB00, 0x00110xFC00, 0x00120xFA00, 0x00120xFB00, 0x00120xFC 00.

And selecting any one of the multiple coding combinations as a first preset conversion intermediate parameter, carrying out conversion processing on the conversion parameter according to a preset second conversion algorithm, and determining whether a preset compensation value is obtained. If not, selecting the next coding combination from the multiple coding combinations as a first preset conversion intermediate parameter, and performing conversion processing on the conversion parameter according to a preset second conversion algorithm until a preset compensation value is obtained or processing of performing a second conversion algorithm on the conversion parameter by using all the coding combinations is completed.

That is, finally, the printer performs conversion processing according to a first preset conversion intermediate parameter and a conversion parameter according to a preset second conversion algorithm to obtain a preset compensation value, and determines a target imaging control parameter meeting a preset imaging condition according to the preset algorithm based on the preset compensation value and a preset imaging control high-voltage parameter.

Or, if the printer does not obtain the preset compensation value after the printer completes the processing of the second conversion algorithm on the conversion parameters by using all the coding combinations, the first detection unit and/or the second detection unit may be abnormal, that is, the sensor at the printer side and/or the sensor at the chip side are abnormal, and then an alarm prompt is given to remind the user to check and replace the sensors in time.

So far, the printer and the consumable chip complete interaction.

According to the image forming control method provided by the embodiment of the application, the preset compensation value of the imaging control high-voltage parameter is encrypted and decrypted based on the environmental data and transmitted by utilizing the environmental data obtained by respective detection of the consumable chip and the image forming device, so that the preset compensation value is prevented from being intercepted and falsified in the transmission process, the data transmission is safer, and the printing imaging quality is further ensured.
