[0001] This application relates to the field of electronic equipment, specifically to a device control method, apparatus, terminal equipment, and computer-readable storage medium. Background Technology

[0002] In current electronic devices, to ensure rapid response to infrared remote control signals or physical button operations even when the device is powered off, a "standby power-on" design is commonly used. Taking projectors as an example, when a user performs a power-off operation through the UI, the standby power supply, specifically designed for standby functionality, continues to run. Even when the device is in a state perceived as "completely off" by the user, the standby power supply still needs to continuously power the main system and other components in standby mode, resulting in significant power loss for battery-powered devices (such as portable projectors and smart speakers) during long-term storage.

[0023] In this embodiment, the terminal device 100 is mainly used to disconnect the main system from the power supply when it is determined that the main system is in a power-off state; after receiving the power-on signal, it controls the main system to connect to the power supply.

[0028] It should be noted that, Figure 1 The schematic diagram of the equipment control system shown is merely an example. The equipment control system and scenario described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of equipment control systems and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0029] First, this application provides a device control method. The execution subject of the device control method is a device control device, which is located in a microcontroller unit (MCU) in a terminal device. The device control method includes: disconnecting the main system from the power supply when it is determined that the main system is in a power-off state; and controlling the main system to connect to the power supply after receiving a power-on signal.

[0030] Figure 2 This is a flowchart illustrating one embodiment of the device control method provided in this invention, as shown below. Figure 2 The diagram shown is a flowchart of an embodiment of the device control method in this application. This device control method is applied to the microcontroller of a terminal device. The terminal device also includes a power supply and a main system. The power supply provides power to the microcontroller and the main system. The device control method may include the following steps S201 to S202, as detailed below: Step S201: When it is determined that the main system is in a power-off state, disconnect the main system from the power supply.

[0031] In one specific embodiment, the terminal device can be a device with a built-in battery as its power source, capable of operating without being connected to an external power source. Examples include smartphones, tablets, smartwatches or bracelets, smart speakers, smart cameras, smart projectors, and smart door locks. This embodiment does not impose specific limitations. The main system can be the core operating system or control center in the smart terminal device, used to manage hardware resources, run applications, coordinate device functions, and interact with the user. The hardware device upon which the main system relies can be a set of integrated circuits integrating one or more processors and one or more memories.

[0032] In this invention, the microcontroller, the execution subject, is set up independently of the integrated circuit on which the main system relies. That is to say, when the main system is powered off, the microcontroller can receive power and can execute the device control method in this application independently of the main system. Whether the main system is powered off or not does not affect whether the microcontroller is powered off.

[0033] Furthermore, the microcontroller can control whether the power supply within the terminal device supplies power to the main system. When the microcontroller determines that the main system has been shut down, in order to prevent the backup modules in the main system from still consuming power, it can directly disconnect the main system from the power supply, which can effectively reduce power consumption and thus reduce the overall energy consumption of the terminal device.

[0034] Step S202: After receiving the power-on signal, control the main system to connect to the power supply.

[0035] In one specific embodiment, since the main system cannot connect to the power supply and start automatically when the power is off, the microcontroller needs to control the main system to connect to the power supply after receiving the power-on signal so that the power supply can supply power to the main system and enable the terminal device to work normally.

[0036] In one specific embodiment, the power-on signal is an instruction or electrical signal that triggers the terminal device to switch from a power-off state to a running state. It can be triggered in various ways. For example, it can be triggered by the user, such as when the user presses the power button, which triggers an electrical signal as a switch signal; or when the user presses the remote control, which emits an infrared signal, and the infrared receiver in the terminal device receives the infrared signal and generates an electrical signal as a switch signal; or it can be triggered automatically by the device, such as when the user sets a timed power-on, and the device automatically triggers an electrical signal as a switch signal at the predetermined time; or the device can automatically trigger an electrical signal as a switch signal when it detects that a charger is connected; or other devices can send a specific data packet to the terminal device via a wireless connection, and the terminal device automatically triggers an electrical signal as a switch signal when it parses the data packet as a power-on instruction. This embodiment does not impose any specific limitations.

[0037] In one specific implementation, the terminal device further includes a power conversion device, through which the power supply is connected to the main system. The microcontroller includes a first pin, which is connected to the enable pin of the power conversion device. Step S201 disconnects the main system from the power supply, specifically including: controlling the first pin to output a first level signal so that the power conversion device is in a turned-off state; Step S202 connects the main system to the power supply, specifically including: controlling the first pin to output a second level signal so that the power conversion device is in a working state.

[0038] In one specific embodiment, a power conversion device is a device used to adjust the form of power, current, or electrical energy. It can convert one type of power supply (such as high voltage) to another type (such as low voltage) to ensure that electronic components with different requirements within the terminal device can be powered by a power supply that meets their needs. The power conversion device has an enable pin, which is used to control the operating state of the power conversion device, including an operating state and a shutdown state.

[0039] Therefore, a power converter can be used as an intermediate component connecting the power supply and the main system. The power converter converts the fixed voltage and current supplied by the power supply to the specifications required by the main system. In this case, the microcontroller can control the on / off state of the circuit between the power supply and the main system by controlling the switching of the power converter. Specifically, the first pin of the microcontroller can be connected to the enable pin of the power converter. The first pin outputs a first-level signal to turn off the power converter, and a second-level signal to turn it on. The first-level signal can be low, and the second-level signal can be high; that is, the power converter is off when the enable pin is low, and on when the enable pin is high. The first and second level signals can be flexibly set, and this embodiment does not impose specific limitations.

[0040] In one specific implementation, the terminal device further includes an infrared receiver and a power button, and the microcontroller further includes a second pin and a third pin, with the second pin connected to the infrared receiver and the third pin connected to the power button. After receiving the power-on signal, before the control system connects to the power supply, the following steps are also included: acquiring the level signal of the second pin and the level signal of the third pin; and determining whether the power-on signal has been received based on the level signal of the second pin and the level signal of the third pin.

[0041] In one specific embodiment, the terminal device can interact with the user based on an infrared receiver and a power button. The microcontroller can be connected to the infrared receiver via a second pin and to the power button via a third pin. When a user interacts with the terminal device using a remote control capable of generating infrared signals, the remote control generates an infrared signal corresponding to the operation and sends it to the terminal device. The infrared receiver in the terminal device receives this infrared signal and converts it into an electrical signal, which is then input to the microcontroller via the second pin. When the user interacts with the terminal device using the power button, pressing the power button generates a voltage level signal, which is input to the microcontroller via the third pin. Therefore, the microcontroller can determine whether a power-on signal has been received by acquiring the voltage levels of the second and third pins.

[0042] In one specific implementation, determining whether a power-on signal has been received based on the level signals of the second pin and the third pin includes: determining that a power-on signal has been received when the level signal of the second pin is the third level signal, or when the level signal of the third pin is the fourth level signal; and determining that a power-on signal has not been received when the level signal of the second pin is neither the third level signal nor the fourth level signal.

[0043] In one specific embodiment, the electrical signal generated when a button is pressed can be configured to be different from the electrical signal in the circuit when the button is idle, and the electrical signal obtained by the infrared receiver from the infrared signal can be configured to be different from the electrical signal in the circuit when no infrared signal is received. For example, the electrical signal obtained by the infrared receiver from the infrared signal can be configured to be a third level signal, and the electrical signal in the circuit when no infrared signal is received can be a different level signal than the third level signal; a fourth level signal can be configured to be generated when a button is pressed, and the electrical signal in the circuit when the button is idle can be a different level signal than the fourth level signal. Specifically, the third level signal can be configured to be a high level signal and the fourth level signal can also be configured to be a low level signal and the fourth level signal can also be configured to be a low level signal, or the third level signal can be configured to be a high level signal and the fourth level signal can be a low level signal. This embodiment does not impose specific limitations.

[0044] Therefore, when the microcontroller determines that the level signal in the second pin is a third level signal, or the level signal in the third pin is a fourth level signal, it can be assumed that the user has pressed a button or operated the remote control, and a power-on signal can be confirmed. However, if the microcontroller determines that the level signal in the second pin is not a third level signal, but some other level signal different from the third level signal, and the level signal in the third pin is not a fourth level signal, but some other level signal different from the fourth level signal, it can be assumed that the user has neither pressed a button nor operated the remote control, and a power-on signal can be confirmed.

[0045] It's important to note that the third and fourth level signals on the second pin indicate that the user has pressed a button or operated the remote control. However, typically, the same button represents both power on and power off. Powering on via remote control also involves pressing the same button on the remote. In other words, the user's action to power on and power off is identical, resulting in the same signal: either a third or fourth level signal. Therefore, the microcontroller cannot directly determine if the user intends to power on based solely on the received third or fourth level signal. Instead, it must have previously determined that the main system was powered off, thus indicating a power-on intention. Conversely, if the main system was previously connected to the power supply, it indicates a power-off intention. In summary, after receiving a third or fourth level signal, the microcontroller can also check the most recent connection operation between the main system and the power supply to determine whether the connection was established or terminated, thus determining whether the received signal is a power-on or power-off signal. Of course, if other circuits are set at the infrared receiver and the button so that the third and fourth level signals can only represent the user's intention to turn on the device, and other level signals can represent the user's intention to turn off the device, then the microcontroller can directly determine that it has received the power-on signal.

[0046] In one specific implementation, the microcontroller further includes a fourth pin, which is connected to the main system; before disconnecting the main system from the power supply when it is determined that the main system is in a power-off state, the microcontroller further includes: acquiring the level signal of the fourth pin; and determining whether the main system is in a power-off state based on the level signal of the fourth pin.

[0047] In one specific embodiment, the microcontroller can determine whether the main system is powered off by the level signal on the fourth pin connected to the main system. After confirming that the main system is powered off, it disconnects the main system from the power supply. The main system can automatically shut down based on the user's shutdown operation, ensuring that all tasks terminate in an orderly manner, the hardware is stable, and the data is intact. The microcontroller then disconnects the main system from the power supply after confirming that the main system has automatically shut down. If the microcontroller directly cuts off the power to the main system based on the user's shutdown operation, data corruption, loss of unsaved files, missing system files, configuration errors, and even disk hardware damage may occur in the main system.

[0048] It should be noted that the main system can receive signals indicating the user's intention to shut down in several ways. For example, the main system can be connected to the power button to receive the electrical signal triggered by the user pressing the power button; it can also be connected to an infrared receiver to receive the electrical signal generated by the infrared receiver in response to the user's operation of the remote control to shut down; it can also be connected to a timer to receive the electrical signal triggered by the user setting a timer to shut down; and it can also be connected to a wireless receiver to receive the electrical signal generated by the wireless receiver in response to the user sending a specific data packet indicating shutdown to the terminal device via other wireless devices. Of course, if the infrared receiver and the power button are already connected to the microcontroller, and the microcontroller is in turn connected to the main system, the microcontroller can transmit the level signals generated by the infrared receiver and the power button to the main system, causing the main system to automatically power on or off.

[0049] In one specific implementation, the system determines whether it is in a power-off state based on the level signal of the fourth pin. Specifically, this includes: determining that the main system is in a power-off state when the level signal of the fourth pin is the fifth level signal; and determining that the main system is not in a power-off state when the level signal of the fourth pin is the sixth level signal.

[0050] In one specific embodiment, when the main system is operating normally, the key pins connected to the fourth pin in the main system will maintain a specific voltage level (such as high or low level). These states are directly controlled by the main system power management circuit or the main control chip. When the main system enters the shutdown process, the power management module will gradually cut off the internal power supply of the main system or adjust the pin output, causing a significant change in the voltage level of the key pins. For example, when the main system is powered on, it may output a continuous high-level signal through the key pin to drive an indicator light or activate an external device, while the key pin will become low when powered off. Alternatively, the main system may output a specific voltage through a dedicated power status pin, which is high when powered on and low when powered off. The external circuit only needs to detect the voltage level of this pin to know the system status.

[0051] The microcontroller can connect to a critical pin or power status pin of the main system via its fourth pin to determine whether the main system is powered off by judging the level signal on the fourth pin. When the level signal on the fourth pin is the fifth level signal, it is determined that the main system is powered off; when the level signal on the fourth pin is the sixth level signal, it is determined that the main system is not powered off. The fifth level signal can be low, and the sixth level signal can be high; this embodiment does not impose any limitations.

[0052] In practice, considering signal delay and noise interference, the pin level may not change immediately after the main system is powered off. You can wait for a period of time (such as several hundred milliseconds) before testing, or confirm that the level is stable by sampling multiple times.

[0053] In one specific implementation, after disconnecting the main system from the power supply, the following steps are also included: entering a sleep mode to reduce power consumption, wherein in the sleep mode, only a preset signal is responded to, and the preset signal includes the third level signal of the second pin and the fourth level signal of the third pin.

[0054] In one specific embodiment, to further reduce power consumption, after disconnecting the main system from the power supply, the microcontroller can also enter a low-power sleep mode, responding only to pre-set signals. For example, the microcontroller's main clock can be turned off, and it can only be woken up by externally input signals (such as third-level and fourth-level signals) or signals generated by timers. Such a deep sleep mode consumes very little power, typically in the microamplitude range, which can greatly reduce power consumption in powered-off terminal devices while ensuring that powered-off terminal devices can be successfully woken up.

[0055] Figure 3 This is a schematic diagram of a specific embodiment of a circuit for controlling a device provided in this invention. The circuit is located in a terminal device and includes a microcontroller 301, a main system 302, a power supply 303, a low-dropout linear regulator 304, a power conversion device 305, an infrared receiver 306, and a power on / off button 307. Figure 3 As shown, the power supply powers the microcontroller and infrared receiver through a low-dropout regulator (LDO), which provides a stable and low-noise DC voltage for the microcontroller and infrared receiver. The power supply also powers the main system through a power converter. Meanwhile, the microcontroller is communicatively connected to the infrared receiver, the power button, the power converter, and the main system, meaning that the microcontroller can receive level signals sent by the infrared receiver, the power button, the power converter, and the main system.

[0056] The microcontroller is connected to the infrared receiver via IO1 to receive level signals (pin 2 mentioned earlier); it is also connected to the power button via IO2 to receive level signals (pin 3 mentioned earlier); it is connected to the power converter via IO3 to output level signals (pin 1 mentioned earlier); and it is connected to the main system via IO4 to receive level signals (pin 4 mentioned earlier).

[0057] Furthermore, based on Figure 3 One circuit connection method is provided. Figure 4 This is a flowchart illustrating a specific embodiment of the device control method provided in this invention, as shown below. Figure 4As shown, when the terminal device is powered off, the microcontroller detects that IO4 is pulled low by the main system (i.e., receives a low-level signal through IO4). After a 500-millisecond delay, after confirming that the main system has completely completed the power-down process, it controls IO3 to pull the enable pin of the power conversion device low (i.e., outputs a low-level signal to the enable pin through IO3), thus shutting down the main system power. After shutting down the main system power, the microcontroller enters sleep mode. In this mode, the power consumption of the microcontroller is further reduced. At the same time, the microcontroller cannot perform complex responses and can only respond to the level signals emitted by the infrared receiver and the power button. During this stage, the power supply only supplies power to the low-power microcontroller and infrared receiver through a low-dropout linear regulator, and the power supply enters low-power mode. After entering low-power mode, the microcontroller continuously responds to the level signals emitted by the infrared receiver and the power button. When it captures the level signal indicating power-on, it pulls IO3 high to turn on the main system power supply, and the entire device powers on.

[0058] To better implement the device control method in the embodiments of this application, based on the device control method, this application also provides a device control apparatus, applied to a microcontroller of a terminal device. The terminal device further includes a power supply and a main system, the power supply being used to power the microcontroller and the main system, such as... Figure 5 As shown, the equipment control device 500 includes: The power shutdown module 510 is used to disconnect the main system from the power supply when it is determined that the main system is in a power-off state; The power connection module 520 is used to control the connection between the main system and the power supply after receiving a power-on signal.

[0059] In this embodiment, by setting a device control unit within the terminal device, the device control unit disconnects the main system from the power supply when it determines that the main system is in a powered-off state; upon receiving a power-on signal, it controls the main system to reconnect to the power supply. This allows the main system to be disconnected from the power supply after it is powered off, reducing energy consumption during the terminal device's power-off period. It also ensures that the main system is powered on upon receiving a power-on signal, guaranteeing the normal power-on of the terminal device. The device control unit can be housed within the microcontroller mentioned earlier.

[0060] In some embodiments of this application, the terminal device further includes a power conversion device, through which the power supply is connected to the main system. The device control device includes a first pin, which is connected to the enable pin of the power conversion device.
