[0061] Figure 1 is a schematic diagram of the connection between an image forming device and a consumable chip provided in an embodiment of the present application. As shown in Figure 1, the image forming device is provided with a first connecting pin and a second connecting pin, and the consumable chip is provided with a first connecting terminal and a second connecting terminal. The consumable chip is installed on the consumable, and the consumable is detachably installed on the image forming device. When the consumable is installed on the image forming device, the first connecting terminal is connected to the first connecting pin, and the second connecting terminal is connected to the second connecting pin. At this time, data communication can be carried out between the image forming device and the consumable chip. It should be pointed out that the image forming device in Figure 1 is only an exemplary description. In actual applications, the image forming device may also be provided with other input and output pins, which is not limited in the embodiment of the present application.

[0062] In the technical solution provided in the embodiment of the present application, only two connection terminals are provided on the consumable chip, which reduces the number of connection terminals provided on the consumable chip, thereby reducing the probability of poor contact between the consumable and the image forming device and improving communication reliability.

[0063] FIG2 is a schematic diagram illustrating the connection between another image forming device and a consumable chip according to an embodiment of the present application. As shown in FIG2 , the consumable chip includes a control unit 11. The control unit 11 may be a microcontroller unit (MCU), a programmed processor, an ASIC (Application Specific Integrated Circuit), or an FPGA (Field Programmable Gate Array), or may be a control circuit composed of multiple circuit components. The control unit 11 is configured to obtain an input signal sent by the image forming device via a first connection terminal and a second connection terminal, and generate first communication data based on the frequency of the input signal.

[0064] In the embodiment of the present application, the consumable chip further includes a current regulating module 12. The current regulating module 12 is connected to the control unit 11. The control unit 11 is further configured to control the current regulating module 12 to generate a current signal based on the first data to be transmitted, and to transmit the generated current signal to the image forming device via the first connection terminal and the second connection terminal, so that the image forming device generates second communication data based on the current signal, wherein the second communication data matches the first data to be transmitted.

[0065] Specifically, the control unit 11 controls the current regulating module 12 to regulate the current of the circuit to form a current signal according to the first data to be transmitted, wherein the first data to be transmitted includes data that the consumable chip needs to transmit to the image forming device.

[0066] In an embodiment of the present application, the consumable chip further includes a signal acquisition unit 111 and a signal processing unit 112. The signal acquisition unit 111 is connected to the signal processing unit 112. The signal acquisition unit 111 is configured to acquire an input signal. The signal processing unit 112 is configured to generate at least a portion of the first communication data based on the frequency of the input signal. It is understood that the signal acquisition unit and the signal processing unit may be provided within the control unit or independently of the control unit in the consumable chip.

[0067] In the embodiment of the present application, the input signal may be converted into a digital signal, and the control unit determines the first communication data according to the digital signal.

[0068] Specifically, the input signal may include a first input signal, a second input signal, or a first input signal and a second input signal, wherein the first input signal and the second input signal have different frequencies. When the frequency of the input signal is less than or equal to a preset frequency, it is considered the first input signal, and the frequency of the first input signal is the first frequency. Conversely, when the frequency of the input signal is greater than the preset frequency, it is considered the second input signal, and the frequency of the second input signal is the second frequency. Correspondingly, the first communication data may include the first data, the second data, or the first data and the second data. When the input signal includes the first input signal, the signal processing unit 112 is specifically configured to generate the first data based on the first input signal; or, when the input signal includes the second input signal, the signal processing unit 112 is specifically configured to generate the second data based on the second input signal; or, when the input signal includes the first input signal and the second input signal, the signal processing unit 112 is specifically configured to generate the first data based on the first input signal and generate the second data based on the second input signal. For example, when the input signal is the first input signal, the corresponding first data is set to 0, and when the input signal is the second input signal, the corresponding second data is set to 1. For another example, when the input signal is a first input signal, the corresponding first data is set to 1, and when the input signal is a second input signal, the corresponding second data is set to 0. This embodiment of the present application is not limited to this.

[0069] Figure 3 is a schematic diagram of an input signal provided in an embodiment of the present application. As shown in Figure 3, the second data to be transmitted includes 0b01101110, i.e., first data, second data, second data, first data, second data, second data, second data, first data. The image formation control unit 21 then controls the voltage generation unit 22 to sequentially output electrical signals of the first frequency, second frequency, second frequency, first frequency, second frequency, second frequency, second frequency, second frequency, and first frequency. The first frequency is different from the second frequency. In the example, the first frequency is lower than the second frequency, but in actual applications, the first frequency can also be higher than the second frequency, and this embodiment of the present application is not limited to this. The voltage generation unit 22 generates an input signal based on each electrical signal and sends the input signal to the control unit 11. The control unit 11 generates the first communication data based on the frequency of the input signal. The process of the control unit 11 generating the first communication data based on the frequency of the input signal is the process of identifying the second data to be transmitted, thereby enabling data communication from the image forming device to the consumable chip. Furthermore, the use of frequency transmission signals can improve anti-interference performance and increase the accuracy of information transmission.

[0070] In the embodiment of the present application, the consumable chip further includes a voltage conversion module 13, which is connected to the control unit 11 and the current regulation module 12. The voltage conversion module 13 is configured to convert the acquired input signal into a voltage and output a stable DC voltage to power the control unit 11. For example, the DC voltage may be a 5V DC voltage.

[0071] In an embodiment of the present application, the consumable chip further includes a power storage module 14, which is connected to the control unit 11 and the voltage conversion module 13. The voltage conversion module 13 is also used to charge the power storage module 14. The power storage module 14 is used to store electricity. The charged power storage module 14 can serve as a power source for the control unit 11, thereby providing power to the control unit 11 and preventing power outages in the control unit 11. For example, the power storage module 14 can be a capacitor, a battery, an inductor, or other components, which are not limited in this embodiment of the present application.

[0072] In the embodiment of the present application, the control unit 11 , the voltage conversion module 13 and the power storage module 14 are grounded.

[0073] In the embodiment of the present application, a consumable is detachably mounted on the image forming device, and a consumable chip is mounted on the consumable. The image forming device includes an image forming control unit 21 and a voltage generating unit 22. The image forming control unit 21 is connected to the voltage generating unit 22, and the voltage generating unit 22 is grounded. The image forming control unit 21 is configured to control the voltage generating unit 22 to generate an input signal based on the second data to be transmitted, and to send the input signal to the control unit 11, so that the control unit 11 generates the first communication data based on the frequency of the input signal.

[0074] Specifically, the image formation control unit 21 controls the voltage generation unit 22 to generate an electrical signal to form an input signal based on the second data to be transmitted. The second data to be transmitted includes data that the image forming apparatus needs to transmit to the consumable chip. For example, the voltage generated by the voltage generation unit 22 is a +5V voltage relative to ground or a -5V voltage relative to ground.

[0075] In the embodiment of the present application, the image forming apparatus further includes a current detection unit 23, which is connected to the image forming control unit 21 and the voltage generating unit 22. The current detection unit 23 is configured to detect the current value of a current signal sent from the consumable chip to the image forming apparatus and transmit the current value to the image forming control unit 21; the current signal includes a first current signal having a first current value; and the image forming control unit 21 is further configured to generate second communication data based on the current signal.

[0076] In an embodiment of the present application, the current signal further includes a second current signal having a second current value, the second current value being different from the first current value, and the second communication data includes third data and / or fourth data. When the current signal includes the first current signal, the image formation control unit 21 is specifically configured to generate the third data based on the first current signal; or, when the current signal includes the second current signal, the image formation control unit 21 is specifically configured to generate the fourth data based on the second current signal; or, when the current signal includes the first current signal and the second current signal, the image formation control unit 21 is specifically configured to generate the third data based on the first current signal and generate the fourth data based on the second current signal.

[0077] FIG4 is a schematic diagram of a current signal provided in an embodiment of the present application. As shown in FIG4 , the first data to be transmitted includes 0b10100011, i.e., fourth data, third data, fourth data, third data, third data, third data, fourth data, and fourth data. The control unit 11 controls the current regulation module 12 to adjust the current value of the loop to, in sequence, the second current value, the first current value, the second current value, the first current value, the first current value, the first current value, the second current value, and the second current value. The first current value is different from the second current value. In the example, the first current value is less than the second current value, but in actual applications, the first current value may also be greater than the second current value, and this is not limited in this embodiment of the present application. The current regulation module 12 generates a current signal based on the current value, and transmits the current signal to the current detection unit 23 via the first and second connection terminals. The current detection unit 23 detects the current value of the current signal and transmits the current value to the image formation control unit 21, which generates the second communication data based on the current value. The process of the image forming control unit 21 generating the second communication data according to the current value of the current signal is the process of identifying the first data to be transmitted, thereby realizing data communication from the consumable chip to the image forming device.

[0078] In the embodiment of the present application, when the consumable is installed in the image forming apparatus, the first connection terminal is connected to the first connection pin, and the second connection terminal is connected to the second connection pin. At this point, the current regulating module 12, the voltage conversion module 13, and the voltage generating unit 22 form a loop. When the control unit 11 controls the current regulating module 12 to generate a current signal based on the first data to be transmitted, the current in the loop changes, but the voltage in the loop remains unchanged.

[0079] Figure 5a is a schematic diagram of a data distribution method provided in an embodiment of the present application. As shown in Figure 5a, the second data to be transmitted includes two sets of data, namely, first information data and second information data. The first information data is 0b00010001, and the second information data is 0b11101110. 0b indicates that both the first information data and the second information data are binary data. The first information data and the second information data are distributed sequentially, that is, the frequencies corresponding to the data 0001000111101110 are sequentially set in the input signal.

[0080] Figure 5b is a schematic diagram of another data distribution method provided in an embodiment of the present application. As shown in Figure 5b, the second data to be transmitted includes two groups of data, namely, first information data and second information data. The first information data is 0b00010001, and the second information data is 0b11101110. The first information data and the second information data are interlaced, that is, the frequency corresponding to the data 0101011001010110 is set in the input signal. The odd bits are the first information data, and the even bits are the second information data. In actual applications, the data distribution method in the input signal can be set according to actual needs, and the embodiment of the present application does not limit this.

[0081] Similarly, when the first data to be transmitted includes more than two groups of data, the data distribution method in the current signal can also be set according to actual needs, and the embodiment of the present application is not limited to this.

[0082] In the technical solution provided in the embodiment of the present application, only two connection terminals are provided on the consumable chip, which reduces the number of connection terminals provided on the consumable chip, thereby reducing the probability of poor contact between the consumable and the image forming device and improving communication reliability.

[0083] In the embodiment of the present application, the clock signal and the data signal can be transmitted simultaneously through the connecting line between the image forming device and the consumable chip, which reduces the data transmission time and thus improves the data transmission efficiency.

[0084] FIG6 is a flow chart of a communication method provided in an embodiment of the present application. As shown in FIG6 , the method includes:

[0085] Step 101: The consumable chip generates a current signal according to first data to be transmitted, and sends the current signal to an image forming device through a first connecting terminal and a second connecting terminal.

[0089] In this step, the image forming device detects the current value of the current signal and generates second communication data based on the current signal. The process of the image forming device generating the second communication data based on the current signal is the process of identifying the first data to be transmitted, thereby achieving data communication from the consumable chip to the image forming device.

[0090] In the technical solution provided in the embodiments of this application, the consumable chip generates a current signal based on the first data to be transmitted and transmits the current signal to the image forming device via the first and second connection terminals. The image forming device then generates second communication data based on the current signal. In this embodiment of the application, the consumable chip serves as the transmitter and the image forming device serves as the receiver, enabling data communication from the consumable chip to the image forming device using the current signal as the carrier.

[0091] In the embodiment of the present application, only two connection terminals are provided on the consumable chip, which reduces the number of connection terminals provided on the consumable chip, thereby reducing the probability of poor contact between the consumable and the image forming device and improving communication reliability.

[0092] FIG7 is a flow chart of another communication method provided in an embodiment of the present application. As shown in FIG7 , the method includes:

[0093] Step 201: The image forming apparatus generates an input signal according to second data to be transmitted, and sends the input signal to a consumable chip.

[0096] Step 202: The consumable chip obtains an input signal through the first connection terminal and the second connection terminal.

[0097] Step 203: The consumable chip generates first communication data according to the input signal.

[0098] In this step, the consumable chip acquires the input signal and generates first communication data based on the frequency of the input signal. The process of the consumable chip generating the first communication data based on the frequency of the input signal is the process of identifying the second data to be transmitted, thereby achieving data communication from the image forming device to the consumable chip.

[0099] In the technical solution provided in the embodiments of this application, the image forming device generates an input signal based on the second data to be transmitted and transmits the input signal to the consumable chip; the consumable chip receives the input signal via the first connection terminal and the second connection terminal; and the consumable chip generates first communication data based on the input signal. In the embodiments of this application, the image forming device is the transmitting end and the consumable chip is the receiving end, and data communication from the image forming device to the consumable chip is achieved using the input signal as the carrier.

[0100] In the embodiment of the present application, only two connection terminals are provided on the consumable chip, which reduces the number of connection terminals provided on the consumable chip, thereby reducing the probability of poor contact between the consumable and the image forming device and improving communication reliability.
