The control module can be a single chip microcomputer or other processors and the like. The first detection terminal of the control module may be a wake-up port, i.e., a wake-up pin. When the external power supply is connected, the first detection end can detect a high level, and the control module can be awakened, namely, the control module is switched to a working state. After the control module is awakened, when the first detection end of the control module can detect the high level lasting for N seconds, and the target button is determined to be triggered for more than the preset time, the control module can control the switch control module to be switched on to supply power to the target device, namely, the target device is controlled to be switched from the non-power-supply state to the power-supply state. And when the target button is not triggered for more than the preset time, the power is not supplied to the target equipment, and the target equipment is in a power-off charging state.
In the above embodiment, the control module may also be awakened by the target button, that is, when the target button is pressed, a triggering edge is generated, and the control module is changed from the dormant state to the active state. After the control module is awakened, the control module starts to continuously monitor the state of the target button, and if the target button is pressed for a long time (for example, for more than 3 seconds), the control module is started to supply power to the target device. That is, the predetermined time may be 3 seconds (this value is merely an exemplary illustration, and the present invention does not limit the time for which the target button is triggered, and may be, for example, 2 seconds, 4 seconds, and the like).
According to the invention, the first detection end of the control module included in the power supply control device is configured to be connected with an external power supply, the external power supply is used for charging a battery module of a target device, the first detection end of the control module is also configured to be connected with a target button, the control end of the control module is connected with the switch control module, the state of the control module is switched to be in a working state under the condition that the first detection end detects that the external power supply is connected or the target button is triggered, the switch control module is controlled to be in an opening and closing state under the condition that the first detection end detects that the target button is triggered for more than a preset time, and the switch control module is used for controlling the target device to be in a power supply state.

And after the target button is detected to be triggered, the control module is switched to a working state, and the switch control module is controlled to be switched on and off to switch the power supply state of the target equipment only under the condition that the target button is triggered for more than preset time. Therefore, the problem of poor system stability caused by repeated power supply for the control module of the target device during charging and starting of the target device in the related art can be solved, and the system stability of the target device during charging is improved.

When the external power supply is switched on, the first input end of the logic module can detect a high level and output the high level. And when the control module detects a high level, the state of the control module is switched to a working state. The high level detected by the first input terminal may be a high level generated when the external power is switched on, or a high level generated when the target button is triggered. Both ways can wake up the control module. That is, when the target device is in the shutdown state, the single chip microcomputer is in the sleep state, the shutdown current is very small (only uA level), at this time, if the target button is pressed, the target button circuit jumps from the low level to the high level, and the jump edge is sent to the first detection end of the control module via the logic module, and the single chip microcomputer can be awakened as well. The target button can be a self-resetting button, and can automatically bounce when being released after being pressed. When the button is pressed down, the signal output of the target button is high level, and when the button is released, the button is self-reset and output to low level.

In the present embodiment, when an external power source is plugged in, since the external power source voltage is higher than the battery module voltage of the target device, power is supplied from the external power source to the power module and the switch control module. At the moment of external power insertion, the external power output voltage jumps from 0V to the power supply voltage, and the voltage jump is captured by the pulse generation module and generates a high level pulse (corresponding to the first pulse signal). The high level pulse is sent to a wake-up pin (corresponding to the first detection terminal) of a single chip microcomputer (a single chip microcomputer is a control module, hereinafter referred to as a single chip microcomputer) via a logic module, and the single chip microcomputer is woken up from a sleep state to a working state.
In an exemplary embodiment, the pulse generating module includes a target capacitor, a first resistor, and a first diode, wherein a first end of the target capacitor is configured to be connected to the external power source, a second end of the target capacitor is connected to the first end of the first resistor, a second end of the first resistor is connected to ground, a second end of the first resistor is further connected to an input end of the first diode, an output end of the first diode is connected to a first input end of the logic module, and a first input end of the logic module is further connected to a second end of the target capacitor.

In an exemplary embodiment, the power supply control device further includes a detection module, wherein a first end of the detection module is configured to be connected to the external power supply, a second end of the detection module is connected to the input end of the pulse generation module, and a second end of the detection module is further connected to a second detection end of the control module, and the detection module is configured to output a target voltage when the external power supply is detected to be connected. In this embodiment, the first end of the detection module may be connected to an external power source, and the second end of the detection module is connected to the second detection end of the control module. When the single chip microcomputer is recovered to a working state from an awakening state, a signal output by the voltage detection module is detected so as to judge whether external power supply is currently performed. And when the external power supply is determined to be accessed, the switch control module is controlled to be started to power on the target equipment. After the target device is powered on, whether the target button is triggered for more than 3 seconds (the time is only an exemplary illustration, the triggering time is not limited in the present invention, the same is applied below) can be detected through the logic module, and if the target button is triggered for more than 3 seconds, the switch control module is controlled to be turned off, and the target device is powered off. If the external power supply is still in the access state detected by the detection module, the target device is in a shutdown charging state.

Referring to fig. 4, as shown in fig. 4, the power supply control apparatus includes: the device comprises a power module, a detection module, a pulse generation module, a logic module, a control module and a switch control module. When the external power source is plugged in, since the external power source voltage is higher than the battery module voltage, power is supplied from the external power source to the power module and the switch control module. At the moment of external power supply insertion, the external power supply output voltage jumps from 0V to the power supply voltage, and the power supply jump is captured by the pulse generation module and generates a high-level pulse. The high-level pulse gives the awakening pin of the single chip microcomputer through the logic module, the single chip microcomputer is awakened to a working state from a dormant state, and the single chip microcomputer can detect a signal output by the voltage detection module when being recovered to the working state from the awakening state so as to judge whether the current power supply is external power supply. In addition, when the equipment is in a shutdown state, the single chip microcomputer is in a dormant state, the shutdown current is very small (only uA level), at the moment, if the button switch is pressed, the button switch circuit jumps from low level to high level, the jumping edge is sent to a wakeup pin of the single chip microcomputer through the logic module, and the single chip microcomputer can be woken up as well.

As shown in fig. 3, the logic module may be an or gate, and performs logical or between the signal generated when the target button is triggered and the pulse signal generated when the external power is switched on. When the button is not pressed and the external power is switched on, the logic module outputs a pulse signal with a high level lasting about 1ms to the MCU to wake up the MCU (corresponding to the control module). When the button is pressed, the logic module will output a high level, also waking up the MCU. When the target button is not triggered and no power-on pulse is generated, the logic module outputs a low level consistent with the power-on button signal.
