Detailed Implementation

[0047] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0048] Currently, in printer applications, the printer needs to be turned on before it can perform functions such as printing, copying, and scanning.

[0049] In one example, due to power consumption requirements, the printer's SOC (System-on-Chips) main control unit does not power on when the power is plugged in. It only powers on and emits a keystroke beep when the power button is pressed. However, in existing technology, because the printer system requires a considerable amount of time to initialize during startup, the delay between the user pressing the power button and the SOC main control unit completing initialization before responding and emitting a keystroke beep results in a poor user experience. Therefore, the overall design is not perfect. In another example, the printer's keystroke beep cannot be turned on or off at the user's end, making keystroke beep control rather limited and unable to meet the needs of various application scenarios.

[0050] This application provides a control device, control method, and printing device for a printing equipment, which aims to solve the above-mentioned technical problems of the prior art.

[0051] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0052] Figure 1 This is a schematic diagram of the structure of a control device for a printing apparatus provided in an embodiment of this application, as shown below. Figure 1 As shown, the control device includes a SOC main control unit, a sound unit, and an MCU control unit for receiving power-on signals; wherein,

[0053] The SOC main control unit is connected to the MCU control unit, which in turn is connected to the sound unit. Both the SOC main control unit and the MCU control unit are used to connect to the power supply. When the SOC main control unit is in a power-off state, if a power-on signal is received, the MCU control unit outputs a power-on signal to connect the SOC main control unit to the connected power supply, thereby starting the printing device; and controls the sound unit to emit a prompt sound.

[0054] For example, such as Figure 1 As shown, the control unit of the printing equipment includes a SOC main control unit, an MCU control unit (hereinafter referred to as Touch MCU) for receiving power-on signals, a buzzer unit, and a power button (POWER KEY). The buzzer unit can be a buzzer, etc.; the power button (POWER KEY) can be a mechanical button or a touch button, etc., and there is no limitation in this regard. The SOC main control unit is connected to the MCU control unit, the MCU control unit is connected to the buzzer unit, the SOC main control unit is connected to the power supply, and the MCU control unit is connected to the power supply.

[0055] Since the MCU control unit is connected to the power supply, if the MCU control unit receives a power-on operation from the user via the POWER KEY button when the SOC main control unit is powered off, it receives a power-on signal. At this time, the MCU control unit is powered on, while the SOC main control unit is not. Then, the MCU control unit outputs a power-on signal to connect the SOC main control unit to the connected power supply. This, in turn, powers on the printer corresponding to the SOC main control unit. Simultaneously, the MCU control unit controls the sound unit to emit a notification sound.

[0056] In this embodiment, the control device includes an MCU control unit, a SOC main control unit, and a sound-emitting unit, both connected to the MCU control unit. The MCU control unit and the SOC main control unit are connected to a power source. When the SOC main control unit is powered off, if a power-on signal is received, the MCU control unit outputs a power-on signal to connect the SOC main control unit to the connected power source, thus starting the printing device. Simultaneously, it controls the sound-emitting unit to emit a prompt sound. Therefore, in this embodiment, by connecting the SOC main control unit to the power source via the MCU control unit, while the SOC main control unit is powering on and initializing to start the printing device, the sound-emitting unit can be controlled to emit a prompt sound in a timely manner. This improves the response speed of the sound-emitting unit, allowing for timely detection of whether a power-on signal has been issued, further enhancing feedback efficiency.

[0057] In one example, Figure 2 A schematic diagram of the structure of a control device for another printing apparatus provided in an embodiment of this application is shown below. Figure 2 As shown, it also includes a power management unit, which is connected to the MCU control unit and the SOC main control unit, and is also used to connect to the power supply.

[0058] The SOC main control unit is used to connect to the power supply through the power management module.

[0059] The MCU control unit is used to output a power-on signal to the power management unit when the SOC main control unit is in a power-off state and a power-on signal is received.

[0060] The power management unit is used to control the SOC main control unit to connect to the power supply when a power-on signal is received.

[0061] For example, such as Figure 2 As shown, the control device includes a Power Management Unit (PMU), an Inter-Integrated Circuit (IIC) bus connecting the SOC main control unit and the MCU control unit, and other keys; the IIC includes TOUCH_SDA and TOUCH_SCL. The Power Management Unit (PMU) is connected to the MCU control unit, the SOC main control unit, and the power supply; the SOC main control unit is connected to the power supply through a power management module. When the SOC main control unit is powered off, if the MCU control unit receives a power-on signal, it outputs a power-on signal to the Power Management Unit. Upon receiving the power-on signal, the Power Management Unit controls the SOC main control unit to turn on the connected power supply.

[0062] In this embodiment, a power management unit is also included. The power management unit is connected to both the MCU control unit and the SOC main control unit, and is also used to connect to a power supply. The SOC main control unit connects to the power supply via the power management module. When the SOC main control unit is in a power-off state, if a power-on signal is received, the MCU control unit outputs a power-on signal to the power management unit. Upon receiving the power-on signal, the power management unit controls the SOC main control unit to turn on the connected power supply according to switch control. Therefore, it is convenient for the MCU control unit to use the power management unit to turn on the power supply connected to the SOC main control unit.

[0063] In one example, such as Figure 2 As shown, the SOC main control unit is also used to send the operating status of the printing device to the MCU control unit; the operating status includes standby status and sleep status.

[0064] For example, such as Figure 2 As shown, an Inter-Integrated Circuit (IIC) bus is established between the SOC main control unit and the MCU control unit. The IIC includes TOUCH_SDA and TOUCH_SCL. After the SOC main control unit is powered on, the printing device enters standby mode. If no printing operation occurs for a long time, the printing device will enter sleep mode. Therefore, the SOC main control unit can determine the operating status of the printing device and send the operating status to the MCU control unit through TOUCH_SCL and TOUCH_SDA in the IIC bus.

[0065] In this embodiment, the SOC main control unit is also used to send the operating status of the printing device to the MCU control unit; the operating status includes standby state and hibernation state. Therefore, the MCU control unit can monitor the operating status of the printing device at any time and issue a prompt sound according to the operating status of the printing device.

[0066] One example also includes a menu panel with multiple operable buttons;

[0067] The MCU control unit is also used to control the sound unit to emit a prompt sound when the printing device is in standby mode and a trigger command for any operable button is received.

[0068] For example, the control device of the printing equipment also includes a menu panel, which includes multiple operable buttons, such as a settings button and a scan button. These operable buttons can be mechanical keys or touch keys, and are not limited thereto. If the MCU control unit determines that the printing equipment is in standby mode, then in standby mode, if it receives a trigger command for any operable button, it controls the sound unit to emit a prompt tone according to the trigger command. The trigger command can be a single click, double click, etc., and is not limited thereto.

[0069] In this embodiment, a menu panel is also included, which includes multiple operable buttons. The MCU control unit is further configured to, when the printing device is in standby mode, control the sound unit to emit a prompt sound if a trigger command is received for any operable button. Therefore, if the printing device enters standby mode, pressing any button on the panel will cause the sound unit to emit a sound.

[0070] In one example, the MCU control unit is also used to control the sound unit to emit a prompt sound when a power-on signal is received while the printing device is in sleep mode.

[0071] For example, if the MCU control unit determines that the printing device is in a sleep state, then if a power-on signal is received while the printing device is in a sleep state, the MCU control unit will control the sound unit to emit a prompt sound according to the power-on signal.

[0072] In this embodiment, the MCU control unit is further configured to control the sound unit to emit a prompt tone when a power-on signal is received while the printing device is in sleep mode. Therefore, if the printing device enters sleep mode, the buzzer will only respond when the power button is pressed.

[0073] In one example, the operable buttons include a settings button;

[0074] The SOC main control unit is also used to acquire setting instructions for the setting button; wherein, the setting instruction indicates to enable or disable the prompt sound function of the sound unit; and sends the setting instruction to the MCU control unit;

[0075] The MCU control unit is also used to control the sound-producing unit to produce sound according to the received setting instructions.

[0076] For example, the operable buttons include a setting button. When the user performs a setting operation on the setting button, the SOC main control unit obtains a setting instruction for the setting button, wherein the setting instruction indicates to enable or disable the prompt sound function of the sound unit. The setting instruction is then written to the MCU control unit via IIC. The MCU control unit obtains this setting instruction, determines the modified status value of the sound unit based on the setting instruction, and writes the modified status value to the internal EEPROM of the MCU control unit, thus permanently disabling the sound unit. The status value of the sound unit will be rewritten to the internal EEPROM when the user re-enables the sound unit's prompt sound. Therefore, during each power-on process, the MCU control unit needs to reread the latest modified status value based on the received setting instruction and control the sound unit to emit sound according to the latest modified status value.

[0077] In this embodiment, the operable button includes a setting button; the SOC main control unit is also used to acquire a setting command for the setting button; wherein, the setting command indicates enabling or disabling the prompt sound function of the sound unit; and sends the setting command to the MCU control unit; the MCU control unit is also used to control the sound unit to emit sound according to the received setting command. Therefore, through the interactive control between the MCU control unit and the SOC main control unit, the prompt sound of the sound unit can be freely turned on and off during the power-on process, providing users with selectivity and adaptably meeting various application scenarios.

[0078] Below, in conjunction with Figure 3 , Figure 4 and Figure 5 Through specific examples, Figure 1 The method shown in the embodiments will be described.

[0079] Figure 3 This is a schematic diagram of the structure of an MCU control unit provided in an embodiment of this application, as shown below. Figure 3 As shown, there are multiple buttons including PAD1, PAD2, ..., PAD(n). PAD1 is the POWER button, PAD2 is the WIFI button, and so on. Further details are omitted here. PAD1 is the power button (capacitive touch) connected to resistor R1038. Resistor R1038 is used to suppress electromagnetic radiation from the MCU control unit.

[0080] Figure 4 This is a schematic diagram of the structure of a driving circuit for a sound-generating unit provided in an embodiment of this application, as shown below. Figure 4 As shown, the driving circuit includes: sound-generating unit LS1, current-limiting resistors (R1025, R1026), pull-down resistor R1027, power supply VDD, diode D22, and transistor Q5.

[0081] Figure 5 This is a schematic diagram of the structure of a touch chip in an MCU control unit provided in an embodiment of this application, as shown below. Figure 5 As shown, the touch chip includes multiple input / output ports such as POWER_KEY, TOUCH_SDA, TOUCH_SCL, and P34 port, as well as power supply VDD.

[0082] Therefore, when the touch chip detects that button PAD1 is pressed, the P34 port of the touch chip outputs a high level, which drives Q5 through R1025, and the sound unit immediately emits sound. Simultaneously, the POWER_KEY outputs a low level to control the SOC main control unit to power on. After powering on, the SOC main control unit communicates with the MCU control unit through TOUCH_SDA and TOUCH_SCL. R1026 is used to prevent excessive load current from the touch chip.

[0083] In one example, this application embodiment provides a control method for a printing device. The printing device includes a control unit, which includes a System-on-Chips (SoC) main control unit, a sound-generating unit, and an MCU control unit for receiving a power-on signal; wherein...

[0084] The SOC main control unit is connected to the MCU control unit, and the MCU control unit is connected to the sound-generating unit. The SOC main control unit and the MCU control unit are respectively connected to the power supply. The method includes:

[0085] When the SOC main control unit is in a power-off state, if the MCU control unit receives a power-on signal, it outputs a power-on signal to connect the SOC main control unit to the connected power supply, thereby starting the printing device; and controls the sound unit to emit a prompt tone.

[0088] When the SOC main control unit is in a power-off state, if the MCU control unit receives a power-on signal, it will output a power-on signal to the power management unit.

[0089] When the power management unit receives a power-on signal, it controls the SOC main control unit to connect to the power supply.

[0090] In one example, the control device further includes a menu panel comprising multiple operable buttons; the method also includes:

[0091] The SOC main control unit sends the operating status of the printing device to the MCU control unit; the operating status includes standby state and sleep state;

[0092] When the printing device is in standby mode, if the MCU control unit receives a trigger command for any operable button, it will control the sound unit to emit a prompt sound according to the trigger command.

[0093] In one example, the MCU control unit is also used to control the sound unit to emit a prompt sound when a power-on signal is received while the printing device is in sleep mode.

[0094] In one example, the operable buttons include a settings button;

[0095] The SOC main control unit is also used to acquire setting instructions for the setting button; wherein, the setting instruction indicates to enable or disable the prompt sound function of the sound unit; and sends the setting instruction to the MCU control unit;

If it is not the power button (POWER KEY), determining the printer's operating status; if the printer is in standby mode, determining if the buzzer is on; if the printer is in hibernation mode or powered off, the process ends.
