Step S10: Control the digital television to scan in real time whether there is a user in the designated area.

If the user is using a digital television device, the user needs to be within a certain distance from the digital television device. This step first selects a designated area as the monitoring area of the digital television device. In the designated area, the digital television device is controlled to scan in real time to determine whether there is a user, and different management strategies are adopted for the power of the digital television device according to whether there is a user.

Further, the step scans whether a user in the designated area adopts a portrait recognition technology or an infrared recognition technology.

Step S20: If there is no user in the designated area within the set time, the digital television device is controlled to enter a standby or power-off state.

If there is no user in the specified area and the set time is exceeded, it means that the user is outside the designated area for a long time. It is very likely that the user has gone out or rested. At this time, the digital TV equipment does not need to continue working for a long time, then the digital TV equipment is controlled to enter. Standby or power-off state to stop the digital TV equipment from working, thereby reducing losses.

In order for the digital television device to enter the standby or power-off state, the user can know that the user can manage the digital television device according to the requirements (for example, if the user needs to record the current program, the standby reservation recording function is required, and the system cannot be directly turned off), this step When the digital television device is controlled to enter the standby or power-off state, a notification is sent to the bound user mobile device to remind the user that if the instruction sent by the mobile device is not received after waiting for the set time, the digital television device enters the standby or power-off state. .

Step S30: Control the digital television device to capture the user's eye image if there is a user in the designated area.

After the user is determined in the scan designated area, the user located in the designated area can determine whether the user is watching the digital television device according to the user's eye state, so the digital television device is controlled to capture the user's eye image. Capturing the user's eye image can use face recognition technology and iris recognition technology.

Step S40: analyzing the user's eye image to determine whether the user has blinking behavior within the set time, and prompting the user to blink if there is no blinking behavior, and controlling the digital television if the user does not blink in the specified time after the prompting The device enters standby or power off state.

For the user's eye image captured in real time, it is judged whether the user has blinking behavior within the set time. If the user has blinking behavior, the user does not enter the sleep state and belongs to the awake state, so the user can effectively judge the blinking behavior of the user. The current state of the user. At the same time, if the user blinks for a long time but does not blink, the user is still awake, but watching the TV program for a long time is easy to cause eye fatigue, which is unfavorable to the user's eyes and vision. This step comprehensively considers the user to be prompted when the user does not blink. Blinking can not only feedback the user's own state but also relax and rest the eyes, further protecting the user's health.

If the user is asleep in the middle of watching the digital television device, the user is likely to be in a position that cannot rest well, such as a sofa or a chair, etc., and the time is too long for the user's rest, especially at night, so the step further includes: After controlling the digital television device to enter the standby state, a timer is started, and an alarm is given to wake up the user when the timer arrives, so that the user can leave the digital television device area for a better rest.

In order to enable the user to know the last usage when using the digital television device again, the step further includes: recording the current time when controlling the digital television device to enter the standby state, and generating a log for the current digital television device usage, the user You can check the log to understand the last usage when you use it.

Compared with the prior art, the digital television device power management method for implementing the embodiment of the present invention can monitor whether there is a user in a designated area of the digital television device in real time, and control the digital television device to perform standby or shutdown operation when there is no user, when there is a user. By capturing the blinking behavior of the user, it is judged whether the user is in a sleep or awake state, and can prompt the user to relax the resting eyes by blinking, which can effectively manage the power supply of the digital television device and ensure the health of the user.

In order to solve the problem that the digital television device continues to work for a long time without being used by the user, the present invention further provides a digital television device power management system. Specifically, FIG. 2 shows a structural diagram of the system in an embodiment, including :

The area scanning unit 100 controls the digital television to scan in real time whether there is a user in the designated area.

At this time, the digital television device does not need to continue to work for a long time, and the scanning processing unit 200 controls. The digital television device enters a standby or power-off state to stop the digital television device from operating, thereby reducing losses.

In order to enter the standby or power-off state of the digital television device, the user can know, so that the user can manage the digital television device according to requirements (for example, the user needs to record the current program, the standby recording function is required, and cannot be directly turned off), and the scanning process is performed. The unit 200 sends a notification to the bound user mobile device to notify the user when the digital television device enters the standby or power-off state, and if the instruction sent by the mobile device is not received after waiting for the set time, the digital television device enters standby or Off state.

The eye image capturing unit 300 controls the digital television device to capture the user's eye image if there is a user in the designated area.

After the user is determined to be in the designated area, the user in the designated area can determine whether the user is watching the digital television device according to the eye state of the user, so the eye image capturing unit 300 controls the digital television device to capture the eye image of the user. . The eye image capturing unit 300 captures the user's eye image using face recognition technology and iris recognition technology.

If the user does not blink after the prompt, the control is performed. The digital TV device enters standby or power off state.

For the user eye image blinking analysis unit 400 captured in real time, it is determined whether the user has blinking behavior within the set time. If the user has blinking behavior, the user does not enter the sleep state and belongs to the awake state, so the blinking analysis unit 400 passes the user pair. The capture of the user's blink behavior can effectively determine the current state of the user. At the same time, if the user blinks for a long time but does not blink, the user is still awake, but the long-term blinking of the TV program is likely to cause eye fatigue, which is unfavorable to the user's eyes and vision. The system considers that the blinking analysis unit 400 does not blink at the user. When the behavior prompts the user to blink, it can feedback the user's own state and relax and rest the eyes, further protecting the user's health.

If the user is asleep while watching the digital television device, the user is likely to be in a position that cannot rest well, such as a sofa or a chair, etc., and the time is too long for the user's rest, especially at night, so the blink analysis unit 400 is controlling. After the digital television device enters the standby state, a timer is started, and an alarm is given to wake up the user when the timer arrives, so that the user can leave the digital television device area for a better rest.

In order to enable the user to know the last usage situation when the user uses the digital television device again, the blink analysis unit 400 records the current time when controlling the digital television device to enter the standby state, and generates a log for the current digital television device usage, under the user You can check the log to understand the last usage when you use it.
