[0043] [Example 1]

[0044] The inventor of this solution found that in the prior art, the power management of electronic whiteboards is mostly manual or simple timed sleep, and cannot be intelligently adjusted according to real-time usage and network status, resulting in excessive power consumption or slow device response, which affects the service life of the device. Embodiment 1 of the present invention provides the following solution:

[0045] like Figure 1 to Figure 2 As shown, this embodiment provides an electronic whiteboard power management method, including:

[0046] Step 101, obtaining the working status information of the electronic whiteboard.

[0047] In some embodiments, the working status information includes display screen status information, audio output status information, input operation status information, network connection status information, and data transmission status information.

[0048] It should be noted that the display status information includes information on the brightness of the display and whether the display is displaying; the audio output status information includes information on the loudness of the audio and whether the audio is making sound; the input operation status information includes information on the number of task processes and whether the task process requires the use of the GPU; the network connection status information includes information on the network transmission rate and whether the network is connected; and the data transmission status information includes information on the data transmission rate and whether data is being transmitted.

[0049] In some embodiments, the wireless connection status information includes WLAN connection status information, WiFi connection status information, and Bluetooth connection status information.

[0050] It should be noted that the WLAN connection status information includes the WLAN network speed information and whether the WLAN is connected. The WiFi connection status information includes the WiFi network speed information and whether the WiFi is connected. The Bluetooth connection status information includes the Bluetooth network speed information and whether the Bluetooth is connected.

[0051] In some embodiments, the data transmission status information includes high-frequency data transmission status information and low-frequency data transmission status information.

[0052] It should be noted that the high-frequency data transmission status information includes information about the high-frequency data transmission rate and whether there is data transmitted at the high frequency, and the low-frequency data transmission status information includes information about the low-frequency data transmission rate and whether there is data transmitted at the low frequency.

[0053] In some embodiments, a display screen status code is obtained through a display screen module, an audio output status code is obtained through an audio module, an input operation status code is obtained through a task management module, a wired network connection status code and a wireless network connection status code are obtained through a network connection module, and a low-frequency data transmission status code and a high-frequency data transmission status code are obtained through a data transmission module.

[0054] It should be noted that the display status code ranges from 0 to 10. When the display status code is 0, it means that the display is turned off, and the range 1-10 represents the brightness of the display. The audio output status code ranges from 0 to 10. When the audio output status code is 0, it means that the audio is stopped, and the range 1-10 represents the loudness of the audio. The input operation status code ranges from 0 to 10. When the input operation status code is 0, it means that no task process is running, and the range 1-10 represents the number of task processes running. The wired network connection status code ranges from 0 to 10. When the wired network connection status code is 0, it means that the wired network is not connected, and the range 1-10 represents the network rate of the wired network connection. The wireless network connection status code ranges from 0 to 10. When the wireless network connection status code is 0, it means that the wireless network is not connected, and the range 1-10 represents the network rate of the wireless network connection. The interval of the low-frequency data transmission status code is 0-10. When the low-frequency data transmission status code is 0, it means there is no low-frequency data transmission. The interval 1-10 represents the transmission rate of the low-frequency data transmission status code. The interval of the high-frequency data transmission status code is 0-10. When the high-frequency data transmission status code is 0, it means there is no high-frequency data transmission. The interval 1-10 represents the transmission rate of the high-frequency data transmission status code.

[0055] Step 102: Perform a logical judgment on the working status code of the electronic whiteboard using a preset threshold.

[0056] In some embodiments, when the sum of the display status code, the audio output status code, and the input operation status code is greater than a first preset threshold, and the sum of the wired network connection status code and the high-frequency data transmission status code is greater than a second preset threshold, the power mode is switched to normal mode (Normal mode).

[0057] When the sum of the display screen status code, the audio output status code, and the input operation status code is less than the first preset threshold, and the sum of the wireless network connection status code and the low-frequency data transmission status code is greater than the third preset threshold, the power mode is switched to the first wireless network standby mode (Network Standby 1 mode).

[0058] When the input operation status code is zero, and the sum of the wireless network connection status code and the low-frequency data transmission status code is less than a third preset threshold, the power mode is switched to the second wireless network standby mode (Network Standby 2 mode).

[0059] For example, the first preset threshold is 18, the second preset threshold is 12, and the third preset threshold is 12. When the sum of the display screen status code, the audio output status code, and the input operation status code is greater than 18, and the sum of the wired network connection status code and the high-frequency data transmission status code is greater than 12, the power mode is switched to the normal mode.

[0060] When the sum of the display screen status code, the audio output status code, and the input operation status code is less than 18, and the sum of the wireless network connection status code and the low-frequency data transmission status code is greater than 12, the power mode is switched to the first wireless network standby mode.

[0061] When the input operation status code is 0, and the sum of the wireless network connection status code and the low-frequency data transmission status code is less than 12, the power mode is switched to the second wireless network standby mode.

[0062] In some embodiments, when the display status code, audio output status code, input operation status code, wired network connection status code, high-frequency data transmission status code, wireless network connection status code, and low-frequency data transmission status code are all zero, the power mode is switched to sleep mode.

[0063] When the display status code, audio output status code, input operation status code, wired network connection status code, high-frequency data transmission status code, wireless network connection status code, and low-frequency data transmission status code are all not zero, the power mode is switched to normal standby mode (Normal Standby mode).

[0064] In some embodiments, when the power mode is switched to the sleep mode, the task management module determines whether there is a task process that will be run after a period of time. If there is a task process that will be run after a period of time, the power mode is switched to the PMS mode; if there is no task process that will be run after a period of time, the current power mode is maintained.

[0065] It should be noted that if it is determined that there is a task process running after a period of time, it actually means that a low power demand situation is detected, and the power mode is low power consumption mode at this time.

[0066] In some embodiments, when the power mode is switched to the PMS mode, it is determined whether the operating state or the network connection state has changed. When the operating state or the network connection state has changed, the working state information of the electronic whiteboard is reacquired and the corresponding power mode is switched.

[0067] Step 103: switch the power mode of the electronic whiteboard according to the result of the logic judgment.

[0068] It should be noted that when the power mode is automatically switched, the electronic whiteboard system can notify the user of the change in the current mode through screen prompts or audio prompts. Users can also manually select different power modes through the interface. The system provides a simple operation interface for users to adjust the power status of the device. When the user performs input operations, the system will automatically switch from sleep mode or low power mode to normal mode to ensure that the device can respond quickly to user operations and improve user experience.

[0083] The data transmission module 305 is used to obtain a low-frequency data transmission status code and a high-frequency data transmission status code.

[0084] It should be noted that the display status code ranges from 0 to 10. When the display status code is 0, it means that the display is turned off, and the range 1-10 represents the brightness of the display. The audio output status code ranges from 0 to 10. When the audio output status code is 0, it means that the audio is stopped, and the range 1-10 represents the loudness of the audio. The input operation status code ranges from 0 to 10. When the input operation status code is 0, it means that no task process is running, and the range 1-10 represents the number of task processes running. The wired network connection status code ranges from 0 to 10. When the wired network connection status code is 0, it means that the wired network is not connected, and the range 1-10 represents the network rate of the wired network connection. The wireless network connection status code ranges from 0 to 10. When the wireless network connection status code is 0, it means that the wireless network is not connected, and the range 1-10 represents the network rate of the wireless network connection. The interval of the low-frequency data transmission status code is 0-10. When the low-frequency data transmission status code is 0, it means there is no low-frequency data transmission. The interval 1-10 represents the transmission rate of the low-frequency data transmission status code. The interval of the high-frequency data transmission status code is 0-10. When the high-frequency data transmission status code is 0, it means there is no high-frequency data transmission. The interval 1-10 represents the transmission rate of the high-frequency data transmission status code.

[0085] The logic judgment module 202 is used to perform logic judgment on the working status code of the electronic whiteboard according to a preset threshold.

[0086] In some embodiments, when the sum of the display status code, the audio output status code, and the input operation status code is greater than a first preset threshold, and the sum of the wired network connection status code and the high-frequency data transmission status code is greater than a second preset threshold, the power mode is switched to normal mode (Normal mode).

[0087] When the sum of the display screen status code, the audio output status code, and the input operation status code is less than the first preset threshold, and the sum of the wireless network connection status code and the low-frequency data transmission status code is greater than the third preset threshold, the power mode is switched to the first wireless network standby mode (Network Standby 1 mode).

[0088] When the input operation status code is zero, and the sum of the wireless network connection status code and the low-frequency data transmission status code is less than a third preset threshold, the power mode is switched to the second wireless network standby mode (Network Standby 2 mode).

[0089] For example, the first preset threshold is 18, the second preset threshold is 12, and the third preset threshold is 12. When the sum of the display screen status code, the audio output status code, and the input operation status code is greater than 18, and the sum of the wired network connection status code and the high-frequency data transmission status code is greater than 12, the power mode is switched to the normal mode.

[0092] In some embodiments, when the display status code, audio output status code, input operation status code, wired network connection status code, high-frequency data transmission status code, wireless network connection status code, and low-frequency data transmission status code are all zero, the power mode is switched to sleep mode.

[0093] When the display status code, audio output status code, input operation status code, wired network connection status code, high-frequency data transmission status code, wireless network connection status code, and low-frequency data transmission status code are all not zero, the power mode is switched to normal standby mode (Normal Standby mode).

If there is a task process that will be run after a period of time, the power mode is switched to the PMS mode; if there is no task process that will be run after a period of time, the current power mode is maintained.

[0095] It should be noted that if it is determined that there is a task process running after a period of time, it actually means that a low power demand situation is detected, and the power mode is low power consumption mode at this time.

[0096] In some embodiments, when the power mode is switched to the PMS mode, it is determined whether the operating state or the network connection state has changed. When the operating state or the network connection state has changed, the working state information of the electronic whiteboard is reacquired and the corresponding power mode is switched.

[0097] The power mode switching module 203 is used to switch the power mode of the electronic whiteboard according to the result of logic judgment.

[0098] It should be noted that when the power mode is automatically switched, the electronic whiteboard system can notify the user of the change in the current mode through screen prompts or audio prompts.
