All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The following describes in detail a control method of a sleep mode according to an embodiment of the present application with reference to the accompanying drawings.
As shown in fig. 1, a flowchart of a sleep mode control method provided in an embodiment of the present application is applied to an electronic device having a driving board, a center control board, and a keypad, where an MCU (Micro controller unit) of the driving board, an MCU (Micro controller unit) of the center control board, and an MCU (Micro controller area network) of the keypad are all mounted on a CAN (controller area network) bus, and the method includes the following steps:

As shown in fig. 2, a flowchart of a specific implementation manner of a sleep mode control method provided in an embodiment of the present application is applied to an electronic device having a driving board, a center control board, and a keypad, and the method includes the following steps:
Wherein, the first preset time period may be 2 minutes.
In step 202, the driver board sends device status information.
Specifically, when the drive board receives a heartbeat data packet or a key data packet from the central control board within a preset time, the drive board sends equipment state information to the central control board; when the drive board receives the heartbeat data packet or the key data packet from the key board within the preset time, the drive board sends the equipment state information to the key board.
The device state information includes a locking state, an AC/DC power supply mode, angle information, altitude information, and the like.
It should be noted that, for an electronic device with a central control board, the driving board may send device status information under the driving of the heartbeat data packet or the key data packet; for electronic devices without a central control board, the driver board may also actively transmit status data information.
And step 203, the driving board sends a sleep instruction packet to each MCU on the CAN bus, writes sleep flag data into a backup register of the driving board, and resets the MCU of the driving board.
The MCU of the driving board, the MCU of the central control board and the MCU of the key board are all mounted on the CAN bus.
And step 204, after the MCU in the drive board is reset, the drive board reads the backup register through the MCU, and if the sleep mark data is read, the function of the IO port of the MCU is configured according to the sleep mode.
Specifically, when the MCU of the drive board reads the sleep mark data from the backup register, the drive board closes the CAN data transmission function of the MCU, so that the MCU is only in a data receiving state, and the power consumption of the MCU in a sleep mode is reduced; the drive board also configures a pin in the MCU, which is responsible for receiving the CAN signal, into a line interruption mode, and the MCU CAN be awakened when data exists on the CAN bus. In this embodiment, the driver board may set a pin in the MCU responsible for receiving the CAN signal as an IO port interrupt function of the general MCU; accordingly, the MCU CAN respond to IO port line interrupts but cannot respond to CAN receive interrupts while in sleep mode.
And step 206, after the MCU in the drive board is reset, the drive board rapidly initializes the non-sleep mode through the MCU.
According to the embodiment of the application, the MCU is switched to the sleep mode by writing the sleep mark data into the backup register, and the function of the IO port of the MCU is configured according to the sleep mode, so that the power consumption of the MCU in the sleep mode can be reduced, the power consumption of electronic equipment is reduced, and the energy is saved.

The third preset time period may be 3 seconds, and the device state information includes a locking state, an AC/DC power supply mode, angle information, altitude information, and the like.
Specifically, when the MCU of the central control board reads the sleep flag data from the backup register, the central control board closes the CAN data transmission function of the MCU, so that the MCU is only in a data receiving state, thereby reducing power consumption when the MCU is in the sleep mode; the central control board also configures a pin responsible for receiving CAN signals and a pin responsible for key input in the MCU into a line interruption mode, and the MCU CAN be awakened when data exists on the CAN bus. In this embodiment, the central control board may set the pin responsible for receiving the CAN signal and the pin responsible for the key input in the MCU as the IO port interrupt function of the common MCU; accordingly, the MCU CAN respond to IO port line interrupts but cannot respond to CAN receive interrupts while in sleep mode.
And step 304, when the CAN line interruption or the key line interruption occurs, the central control board writes the non-sleep flag data into the backup register of the central control board, and resets the MCU of the central control board.
And 305, after the MCU in the central control board is reset, the central control board rapidly initializes a non-sleep mode through the MCU, sends an invalid data packet to the CAN bus, and sends a key data packet to the drive board when detecting the operation of a user on a key on the central control board.
The invalid data packet sent to the CAN bus is used for triggering the MCU which is mounted on the CAN bus and is in a sleep mode in a broadcast mode, and the MCU CAN be awakened by line interruption.
According to the embodiment of the application, the MCU is switched to the sleep mode by writing the sleep mark data into the backup register, and the function of the IO port of the MCU is configured according to the sleep mode, so that the power consumption of the MCU in the sleep mode can be reduced, the power consumption of electronic equipment is reduced, and the energy is saved.
As shown in fig. 4, a flowchart of another specific implementation manner of the sleep mode control method provided in the embodiment of the present application is applied to an electronic device having a driving board, a center control board, and a keypad, and the method includes the following steps:
And 402, when the key board receives a sleep instruction packet from the driving board or the key board does not receive the device state information from the driving board within a third preset time, writing sleep flag data into a backup register of the key board, and resetting an MCU of the key board.
The third preset time period may be 3 seconds, and the device state information includes a locking state, an AC/DC power supply mode, angle information, altitude information, and the like.
And step 403, after the MCU in the keypad is reset, the keypad reads the backup register through the MCU, and if the sleep flag data is read, configures the function of the IO port of the MCU according to the sleep mode.
Specifically, when the MCU of the keypad reads the sleep flag data from the backup register, the keypad closes the CAN data transmission function of the MCU, so that the MCU is only in a data receiving state, thereby reducing power consumption when the MCU is in a sleep mode; the key board also configures the pin responsible for receiving CAN signals and the pin responsible for key input in the MCU into a line interruption mode, and the MCU CAN be awakened when data exists on the CAN bus. In this embodiment, the keypad may set the pin responsible for receiving the CAN signal and the pin responsible for key input in the MCU as the IO port interrupt function of the general MCU; accordingly, the MCU CAN respond to IO port line interrupts but cannot respond to CAN receive interrupts while in sleep mode.
And step 404, when the CAN line interruption or the key line interruption occurs, the key board writes the non-sleep flag data into the backup register of the key board, and resets the MCU of the key board.
And 405, after the MCU in the key board is reset, the key board rapidly initializes the non-sleep mode through the MCU, sends an invalid data packet to the CAN bus, and sends a key data packet to the drive board when detecting the operation of a user on the key board.
The invalid data packet sent to the CAN bus is used for triggering the MCU which is mounted on the CAN bus and is in a sleep mode in a broadcast mode, and the MCU CAN be awakened by line interruption.
