The power supply control device provided by the embodiment of the utility model directly connects the controller to the processor by adding a controller and a recovery power supply, and the recovery power supply is connected to the controller and the power supply control module respectively, so that when the controller monitors the button When the trigger duration meets the standby conditions, the controller can directly send an interrupt signal to the processor through a direct connection with the processor, so that the processor enters the standby state according to the interrupt signal, reducing the complexity of computer standby and power consumption; at the same time increasing The controller replaces the power control module and is directly connected to the button to monitor the real-time trigger of the button, so that the power control module can be turned off in the shutdown state, further reducing power consumption.

The following uses specific embodiments to describe in detail the process of starting up, shutting down and standby of the power control device provided by the embodiment of the present invention.

Boot process:

When the state of the processor 7 is the shutdown state, the controller 3 sends the first power supply signal to the recovery power supply 4 through the connection with the recovery power supply 4 when it detects that the key press duration of the button 2 meets the preset power-on condition. The power supply signal is used to control the recovery power supply 4 to supply power to the power control module 6;

In the specific implementation process, when the state of the computer (that is, the processor 7) is off, only the basic power supply 1 supplies power to the buttons 2 and the controller 3, and neither the recovery power supply 4 nor the working power supply 5 supplies power. When the user presses the button 2, the controller 3 monitors the trigger time of the button 2, and when it is determined that the trigger time is longer than the preset power-on time, it is considered that the preset power-on condition is satisfied; when the trigger time is less than the preset power-on time, it is considered to be an error trigger, the controller 3 will not enter the booting process; the preset booting time is usually set to more than 3 seconds, so as to avoid judging the user's false trigger as a booting signal or other signals. When it is determined that the preset power-on condition is satisfied, it is considered that the user sends a power-on signal to the computer through the button 2. At this time, the controller 3 sends the first power supply signal to the recovery power supply 4, and the first power supply signal is used to control the recovery power supply 4 to start to control the power supply. Module 6 supplies power. After the power control module 6 is normally powered on, it sends a power supply completion signal to the controller 3 . Optionally, a power supply detection module is provided in the power control module 6 to detect whether each power supply circuit in the power control module 6 is normal. After the controller 3 receives the power supply completion signal sent by the power control module 6, it sends a second power supply signal to the power control module 6, and the power control module 6 forwards the second power supply signal to the working power supply 5, and the working power supply 5 transmits the second power supply signal according to the second power supply signal. The power supply signal supplies power to the processor 7 . At this point, the controller 3 records the state of the computer as the power-on state. In the power-on state, the basic power supply 1, the recovery power supply 4 and the working power supply 5 work simultaneously to supply power.

Optionally, the processor 7 also includes a power-on indicator light. When the power-on of the processor 7 is completed, the power-on indicator light becomes bright, so that when the user presses the button 2 to send a power-on signal, it is intuitively determined that the current trigger will not If it is determined to be a false trigger, you can release button 2 when you observe that the power-on indicator light is on.

Standby process:

When the state of the processor 7 is the working state, the controller 3 sends an interrupt signal to the processor 7 through the connection with the processor 7 when it detects that the trigger duration of the button 2 meets the preset standby condition.

The preset standby condition is: the triggering time of the key is longer than the preset standby time and less than the preset shutdown time.

In the specific implementation process, when the state of the computer is the power-on state, when the user presses the button 2, the controller 3 monitors the trigger duration of the button 2, and when it is determined that the trigger duration is greater than the preset standby duration and less than the preset shutdown duration, Then it is considered that the current trigger duration meets the preset standby condition; when the trigger duration is less than the preset standby duration, it is considered to be a false trigger, and the controller 3 does not perform any operation; when the trigger duration is longer than the preset shutdown duration, it is considered that the current trigger duration meets Preset the shutdown condition and enter the shutdown process; when it is determined that the preset standby condition is met, it is considered that the user sends a standby signal to the computer through the button 2. At this time, the controller 3 sends an interrupt signal to the processor 7, and the processor 7 responds to the computer according to the interrupt signal. The internal registers are set to enter the standby state. At this point, the controller 3 records the state of the computer as the standby state. In the standby state, the basic power supply 1, the recovery power supply 4 and the working power supply 5 work simultaneously to supply power.

Wake up process:

When the state of the processor 7 is the standby state, the controller 3 sends a wake-up signal to the processor 7 through the connection with the processor 7 when it detects that the trigger duration of the button 2 meets the preset wake-up condition. The control processor 7 returns to the working state.

Wherein, the preset wake-up condition is: the triggering time of the key is longer than the preset wake-up time and less than the preset power-off time.

In the specific implementation process, when the state of the computer is in the standby state, when the user presses the button 2, the controller 3 monitors the trigger duration of the button 2, and when it is determined that the trigger duration is greater than the preset wake-up duration and less than the preset shutdown duration, It is considered that the current trigger duration meets the preset wake-up condition; when the trigger duration is less than the preset wake-up duration, it is considered to be a false trigger, and the controller 3 does not perform any operation; when the trigger duration is longer than the preset shutdown duration, it is considered that the current trigger duration satisfies Preset the shutdown condition and enter the shutdown process; when it is determined that the preset wakeup condition is met, it is considered that the user sends a wakeup signal to the computer through the button 2. At this time, the controller 3 sends a wakeup signal to the processor 7, and the processor 7 responds to the computer according to the wakeup signal. The internal registers are set, enter the power-on state, and the computer works normally again. At this point, the controller 3 records the state of the computer as the power-on state.

Optionally, the preset shutdown duration in the power-on state and the standby state can be the same.

Shutdown process:

When the controller 3 detects that the triggering duration of the key 2 meets the preset shutdown condition, the controller 3 sends the first power-off signal to the power control module 6 through the connection with the power control module 6, and the power control module 6 passes through the connection with the power control module 6. The connection between the power supplies 5 transmits the first power-off signal to the working power supply 5, and the first power-off signal is used to control the power-off of the working power supply 5; Two power-off signals, the second power-off signal is used to control the power-off of the recovery power supply 4 .

Wherein, the preset power-off condition is: the trigger time of the key is longer than the preset power-off time.

In the specific implementation process, when the state of the computer is the standby state or the power-on state, when the user presses the button 2, the controller 3 monitors the trigger duration of the button 2, and when it is determined that the trigger duration is greater than the preset shutdown duration, it is considered that the current trigger If the duration satisfies the preset shutdown condition, it is considered that the user sends a shutdown signal to the computer through button 2 . At this time, the controller 3 sends the first power-off signal to the power control module 6, and the power control module 6 forwards the first power-off signal to the working power supply 5, and the working power supply 5 stops sending power to the processor 7 according to the first power-off signal. powered by. After the processor 7 is powered off, the controller 3 sends a second power-off signal to the recovery power supply 4 , and the recovery power supply 4 stops supplying power to the power control module 6 according to the second power-off signal. At this point, the controller 3 records the state of the computer as a shutdown state. In the shutdown state, only the basic power supply 1 works to supply power.
