Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0024] Embodiment 1, as Figure 1 shown, the embodiment of the present invention provides a method for optimizing the content display of a digital photo frame, which specifically includes the following steps:

[0025] S100: Obtain the working frequency parameters of multiple smart homes, and analyze the user status according to the working frequency parameters to obtain a user status coefficient.

[0026] Further, step S100 of the present invention further includes:

[0027] S110: Through the Internet of Things, monitor the number of times of working state switching of the multiple smart homes within a recently preset time interval, and sum to obtain the number of times of working state switching.

[0028] Specifically, by means of the Internet of Things, monitor the number of times the working states of multiple smart home devices (such as lamps, automatic curtains, etc.) are switched within a preset time interval, for example, the number of times of turning the lights on or off or adjusting the brightness of the lamps. For example, use a circuit sensor to monitor the working state of the device (such as on / off) in real time and record the time stamp of the state change. The preset time interval can be set according to the actual scenario, such as the last 30 minutes, the last 1 hour, etc. Obtain the number of times the working states of multiple smart homes are switched, and sum up the number of state switches of multiple homes. Take the summation result as the number of working state switches. By obtaining the number of working state switches, it provides a basis for subsequent user state analysis.

[0029] S120: Calculate and obtain the working frequency parameter according to the number of working state switches and the preset time interval.

[0030] Furthermore, step S120 of the present invention further includes:

[0031] S121: Calculate the ratio of the number of working state switches to the preset time interval to obtain the number of working state switches per unit time, which is used as the working frequency parameter.

[0032] Specifically, calculate the ratio of the number of working state switches to the preset time interval to obtain the number of working state switches per unit time, and set it as the working frequency parameter; for example, assume that the number of working state switches within the preset time interval is 9 and the preset time interval is 30 minutes, then the working frequency parameter is 9 / 30 which is equal to 0.3 times per minute.

[0033] S130: Conduct user state analysis according to the working frequency parameter to obtain the user state coefficient.

[0034] Furthermore, step S130 of the present invention further includes:

[0035] S131: Obtain the average working frequency parameter of the user using the smart home in the historical time; S132: Calculate the ratio of the working frequency parameter to the average working frequency parameter to obtain the user state coefficient.

[0036] Specifically, first, obtain the average working frequency parameter of the user's use of smart home within the historical time (such as within the most recent month), that is, collect and record the status switching data of the smart home devices within a period of time, including the time stamps of each switch; then for each device, calculate the total number of switches within the historical time, and divide the total number of switches by the total time interval to obtain the historical average working frequency parameter of the device. Further calculate the ratio of the working frequency parameter to the average working frequency parameter, and set the ratio as the user status coefficient. Among them, if the user status coefficient is greater than 1, it indicates that the current user's activity frequency is higher than the average level, and the user may be in a busy state; if the user status coefficient is less than 1, it indicates that the user may be in a leisure state; the larger the working frequency parameter, the larger the user status coefficient, indicating that the user is busier. At this time, the user pays more attention to the prompt content (such as weather, schedule) of the digital photo frame and less attention to the image content (photos). Therefore, the digital photo frame should update the prompt content (such as weather, schedule reminder) more frequently. The smaller the working frequency parameter, the smaller the user status coefficient, and the more leisure the user is. At this time, the user pays more attention to the image content (photos) and less attention to the prompt content (such as weather, time). Therefore, the digital photo frame should update the image content (photos) more frequently.

[0037] S200: Allocate the weights of the prompt content and the image content according to the user status coefficient.

[0038] Furthermore, step S200 of the present invention further includes:

[0039] S210: Obtain the preset prompt content weight and the preset image content weight, where the sum of the preset prompt content weight and the preset image content weight is 1; S220: Multiply the user status coefficient by the preset prompt content weight to obtain the prompt content weight; S230: Calculate and obtain the image content weight according to the prompt content weight.

[0040] Specifically, obtain the preset prompt content weight and the preset image content weight. The sum of the preset prompt content weight and the preset image content weight is 1. The user can configure the preset prompt content weight and the preset image content weight according to actual needs. For example, if the user pays more attention to the prompt content (such as weather, schedule reminder), the preset prompt content weight is larger; if the user pays more attention to the image content (photos), the preset image content weight is larger. For example, the user can set the preset prompt content weight and the preset image content weight to 0.5 respectively, which means that when the user status is unknown, the importance of the prompt content and the image content is equal.

[0041] Next, multiply the user status coefficient by the preset prompt content weight to obtain the updated prompt content weight. For example, assuming the user status coefficient is 1.4 and the preset prompt content weight is 0.5, the updated prompt content weight is 0.7, indicating that the user pays more attention to the prompt content (such as weather and schedule reminders) in the current state. Then, subtract the updated prompt content weight from 1 to obtain the updated image content weight. For example, assuming the updated prompt content weight is 0.7, the updated image content weight is 1 - 0.7 = 0.3. By configuring the prompt content weight and the image content weight according to the user's current state, the digital photo frame can dynamically adjust the content attention according to the user's current state, better meeting the user's needs.

[0042] S300: According to the prompt content weight and the image content weight, optimize the content display of the digital photo frame to obtain the optimal display parameters including the optimal image content switching frequency and the optimal prompt content update frequency, and perform content display. Among them, the optimization includes calculating the display score according to the image content switching frequency, the prompt content update frequency, and the pixel refresh rate.

[0043] Furthermore, step S300 of the present invention further includes:

[0044] S310: According to the prompt content weight and the image content weight, construct a content display optimization function as follows: where FIT ef is the display score, w t and w f are the prompt content weight and the image content weight, T r is the prompt content update frequency, T y is the preset prompt content update frequency, F r is the image content switching frequency, F y is the preset image content switching frequency, K y is the preset pixel refresh rate of the digital photo frame, and K r is the pixel refresh rate in the optimization.

[0045] Specifically, in the content display optimization function, FIT ef is the display score. The larger the display score, the better the display effect; w t and w f are the prompt content weight and the image content weight; T r is the prompt content update frequency, T y is the preset prompt content update frequency, and the preset prompt content update frequency is the standard prompt content update frequency set according to user needs, such as 20 seconds / time; F r is the image content switching frequency, and F yis the preset image content switching frequency, and the preset image content switching frequency is the standard image content update frequency set according to user requirements, such as 30 seconds / time; K y is the preset pixel refresh rate (standard pixel refresh rate) of the digital photo frame, K r is the pixel refresh rate during optimization. The pixel refresh rate should be reduced as much as possible to reduce energy consumption and slow down device aging, while maintaining a content display effect that satisfies users.

[0046] By constructing a content display optimization function, the display score can be comprehensively evaluated from three aspects: the image content switching frequency, the prompt content update frequency, and the pixel refresh rate, so as to effectively improve the scientificity, rationality, and accuracy of the display score calculation, and provide a reliable basis for optimizing the display parameters.

[0047] S320: According to the content display optimization function, perform content display optimization of the digital photo frame to obtain the optimal image content switching frequency and the optimal prompt content update frequency corresponding to the maximum display score as the optimal display parameters.

[0048] Furthermore, step S320 of the present invention further includes:

[0049] S321: Randomly set the first image content switching frequency and the first prompt content update frequency of the digital photo frame; S322: Calculate and obtain the proportion of pixel refresh in the digital photo frame per second according to the first image content switching frequency and the first prompt content update frequency as the first pixel refresh rate; S323: Based on the content display optimization function, calculate and obtain the first display score according to the first image content switching frequency, the first prompt content update frequency, and the first pixel refresh rate.

[0050] Specifically, first, obtain the image content switching frequency threshold and the prompt content update frequency threshold of the digital photo frame. The image content switching frequency threshold and the prompt content update frequency threshold can be set according to the device production parameters. For example, the image content switching frequency threshold is 3 seconds / time to 100 seconds / time; and randomly select any image content switching frequency and any prompt content update frequency within the image content switching frequency threshold and the prompt content update frequency threshold to obtain the first image content switching frequency and the first prompt content update frequency.

[0051] Next, calculate the proportion of pixel refreshes per second in the digital photo frame according to the first video content switching frequency and the first prompt content update frequency, and set this proportion as the first pixel refresh rate. For example, if the proportion of the video content display area in the digital photo frame is 90%, the proportion of the prompt content display area is 10%, and both the first video content switching frequency and the first prompt content update frequency are 5 times per second, then the proportion of pixel refreshes per second in the digital photo frame is 0.9 / 5 + 0.1 / 5 = 0.2, that is, the first pixel refresh rate is 20%. Further, use the content display optimization function to calculate the first display score of the first display parameter (including the first video content switching frequency and the first prompt content update frequency) according to the first video content switching frequency, the first prompt content update frequency, and the first pixel refresh rate.

[0052] S324: Continue to optimize the content display of the digital photo frame to obtain the optimal video content switching frequency and the optimal prompt content update frequency corresponding to the maximum display score as the optimal display parameter.

[0053] Furthermore, step S324 of the present invention further includes:

[0054] S3241: Continue to randomly set the video content switching frequency and the prompt content update frequency, and calculate the display score; S3242: Until the optimization converges, output the optimal video content switching frequency and the optimal prompt content update frequency corresponding to the maximum display score as the optimal display parameter.

[0055] Specifically, using the same method, continue to randomly select the second video content switching frequency and the second prompt content update frequency within the video content switching frequency threshold and the prompt content update frequency threshold of the digital photo frame, and calculate the second pixel refresh rate; then based on the content display optimization function, calculate the second display score of the second display parameter (including the second video content switching frequency and the second prompt content update frequency) according to the second video content switching frequency, the second prompt content update frequency, and the second pixel refresh rate. Then continue to perform iterative random selection of display parameters and calculation of display scores using the same method until the predetermined convergence number is reached. The predetermined convergence number is the number of times of parameter random selection, which can be set according to the optimization requirements. The higher the optimization accuracy requirement, the larger the predetermined convergence number. When the predetermined convergence number is reached, the optimization converges. At this time, multiple display parameters and multiple display scores are obtained, and the display parameter corresponding to the maximum display score is output as the optimal display parameter. The optimal display parameter includes the optimal video content switching frequency and the optimal prompt content update frequency.

[0056] Finally, control the digital photo frame to perform content display according to the optimal video content switching frequency and the optimal prompt content update frequency.
