[0002] Photo frames are common items in our daily lives and are used to decorate photos as souvenirs.

[0003] Ordinary photo frames currently available on the market do not have electronic devices. Such photo albums are very common and inexpensive, but they cannot automatically change photos. Each time a photo is changed, it needs to be reprinted, which is costly and troublesome to change.

[0004] Although digital photo frames have many functions, they consume a lot of power and require a dedicated power adapter, which has high requirements for the use environment. It is difficult to hang multiple photo frames on the wall together for use as home photo frames, especially because they usually use LCD screen displays, which have strong radiation and cannot be widely used in the home.

[0005] In recent years, some products based on electronic ink screens have appeared. They do not need to be connected to an external power supply, have no radiation, and have low power consumption. However, since low power consumption is not taken into consideration in the design, they still require built-in high-power lithium batteries and need to be charged frequently. There are still safety issues when using them at home, and they cannot be transported by air, making them inconvenient to use.

[0006] None of the above methods can completely solve the problems of automatic photo replacement, multi-functional use, power consumption, radiation, safety, and long-term use of the photo frame. Summary of the invention

[0037] In view of the fact that traditional photo frames cannot change photos at any time, the present invention proposes a multi-level power supply parallel control method based on the advantages of the above various product forms. The main control parallel power supply is controlled by a low-power input wake-up module, and then the main control parallel power supply and the high-power consumption module are controlled by the main control in different application scenarios, thereby greatly reducing the overall power consumption of the device for a long time. Based on the advantages of the electronic ink screen photo frame, dry batteries or button batteries can be used without charging circuits and rechargeable batteries, which can better extend the use time of the device, improve user experience, be safer and more reliable, and lay a good technical design foundation for the upgrading of photo frames and their entry into families.

[0038] In some possible embodiments: see Figure 1 , a new low-power multifunctional photo frame based on wireless communication and electronic ink screen, characterized in that it includes the following modules:

[0039] Electronic ink screen module, main control board, wireless working module, power supply.

[0040] In some possible embodiments: the main control board includes a low-power wake-up input module, a power parallel control circuit, a high-power power control module, and the wireless working module includes but is not limited to Bluetooth, NFC, and WIFI.

[0041] In some possible embodiments: see Figure 2 The power parallel control circuit includes a wake-up circuit, a first-level power control switch, a second-level power control switch, a wireless high-power working module, and a control switch main control circuit; the wake-up circuit sends a switch control signal to the first-level power control switch, and the main control circuit sends a switch control signal to the first-level power control switch and the second-level power control switch.

[0042] The invention proposes a multi-level power supply parallel control method, which controls the main control parallel power supply through a low-power input wake-up module, and then controls the main control parallel power supply and high-power consumption modules in different application scenarios through the main control, thereby greatly reducing the overall power consumption of the device for a long time. Based on the advantages of the electronic ink screen photo frame, it can better extend the device usage time and improve the user experience, laying a good technical design foundation for the upgrading of the photo frame.

[0043] In some possible embodiments: a hanging hole is opened on the back of the frame, and a hinged stud is also provided, through which the frame is hinged to the support frame.

[0044] In some possible embodiments: a timer connected to the MCU main control unit is also provided in the frame.

[0045] In some possible embodiments, a photo frame system of a mobile phone APP is also included.

[0046] Compared with the original traditional photo frame and digital photo frame, the method of the present invention integrates the advantages of the two and eliminates the disadvantages of the two, so that the multifunctional electronic photo frame can be officially introduced into the family, replace the traditional photo frame, and quickly popularize.

[0047] Using the low-power working mode of electronic ink screen and above, when the picture is not changed, the photo frame consumes very little power, so it can work for several years without replacing the battery, which is very convenient; even if there is no power, the photos can still be displayed normally.

[0048] More specific examples of computer-readable media (a non-exhaustive list) include the following: an electrical connection with one or more wires (electronic device), a portable computer disk case (magnetic device), a random access memory (RAM), a read-only memory (ROM), an erasable and programmable read-only memory (EPROM or flash memory), an optical fiber device, and a portable compact disk read-only memory (CDROM). In addition, the computer-readable medium may even be a paper or other suitable medium on which the program is printed, since the program may be obtained electronically, for example, by optically scanning the paper or other medium, followed by editing, deciphering or, if necessary, processing in another suitable manner, and then stored in a computer memory.

[0049] The present application provides a method for low power consumption and multi-function display of an electronic ink screen. Figure 3 , applied to the cloud, in the first embodiment of the electronic ink screen display method of the present application, the electronic ink screen low power consumption multifunctional display method includes:

[0050] Step S1, obtaining image information;

[0051] Step S2, sending image information to the electronic ink screen, so that the electronic ink screen is updated based on the image information.

[0052] It should be noted that the cloud is used to store image information, and is also used to receive background editing instructions from users, accept online editing by users on the cloud, and the cloud and the electronic ink screen are connected in communication, and the cloud and the electronic ink screen can communicate wirelessly. The background template image is a fusion of the background base map, text elements and icon elements. The background base map is an image, which can be an image selected by the user. The text elements and icon elements can also be selected by the user at will, and the background template image can be previewed by the user. The image information is a compressed image file. The cloud can store a large number of background template images, and can also store a large amount of image information related to the background template image, and the cloud can convert the background template image into image information supported by the electronic ink screen. There is no need to convert the background template image on the electronic ink screen, thereby reducing the operating pressure of the electronic ink screen and saving the computing power of the electronic ink screen.

[0053] Exemplarily, the cloud obtains the image information by the cloud responding to the user's background editing instruction, obtaining the background template image, and converting the background template image into image information, or the cloud responds to the update request of the electronic ink screen and determines the image information corresponding to the electronic ink screen update request from the image database in the cloud. Furthermore, the method for the electronic ink screen to receive the image information may be to send an update request to the cloud, and the cloud feeds back the image information matching the update request to the electronic ink screen, wherein the update request includes the name of the updated background, and the image information may also have a corresponding image name, and the image name of the image information matching the updated background name is searched in the cloud; the method for the electronic ink screen to receive the image information may also be that the user can trigger the update instruction of the electronic ink screen in the cloud, and the cloud directly sends the image information to the electronic ink screen to instruct the electronic ink screen to update based on the image information.

[0054] The present application provides a low-power multifunctional display method for an electronic ink screen. In a second embodiment of the electronic ink screen display method of the present application, the low-power multifunctional display method for an electronic ink screen includes:

[0055] Step S100, acquiring image information;

[0056] Step S200, sending image information to the electronic ink screen;

[0057] Step S300 is for the electronic ink screen to update image information based on a preset mode.

[0058] Furthermore, a new low-power multifunctional photo frame based on wireless communication and electronic ink screen includes a power module, and the above step S200 is specifically set to update the electronic ink screen based on the preset mode image information: obtain the power of the power supply as x, obtain the power required for each screen refresh as y, obtain the number of pictures as m, and adjust the picture rotation. If x divided by y minus m is greater than zero, all pictures are rotated. If x divided by y minus m is less than or equal to zero, a random picture is displayed, and the user is reminded that the power is low and to charge in time.

[0059] Furthermore, when the power source is solar energy, a new low-power multifunctional photo frame based on wireless communication and electronic ink screen includes a power module. The above step S200 is specifically set for the electronic ink screen to update the image information based on the preset mode: obtain the power of the power supply as x, obtain the power required for each screen refresh as y, obtain the power generated by the solar cell per minute as n, obtain the number of pictures as m, and adjust the picture rotation according to the power of the power supply as x, the power required for each screen refresh as y, the number of pictures as m, and the power generated by the solar cell per minute as n. When 60n is greater than y, a picture is replaced every hour. When n is much smaller than y, if x divided by y minus m is greater than zero, all pictures are rotated. If x divided by y minus m is less than or equal to zero, a random picture is displayed, and the user is reminded that the power is low and to charge in time.

[0060] The present application embodiment provides a low-power multifunctional display method for an electronic ink screen. In a third embodiment of the electronic ink screen display method of the present application, the electronic ink screen low-power multifunctional display method includes:

[0061] Step S100, acquiring image information;

[0062] Step S500: input the picture information into a pre-built picture emotion detection model for processing, obtain the picture emotion information corresponding to the picture information as the target emotion information, and mark the image information with the emotion information.

[0063] Step S200, sending the image information with emotional information to the electronic ink screen.

[0064] Step S300 is for the electronic ink screen to update image information based on a preset mode.

[0065] The emotional information is: very positive, relatively positive, calm, relatively negative, and very negative.

[0066] In some possible embodiments, the step of identifying the picture is also included: step S500, obtaining the user's image information; in addition, in this embodiment, after obtaining the user's image information, the user's image information can also be uploaded to the cloud, and the user can view his or her own image information through the cloud at any time. S501, input the picture information into a pre-built picture emotion detection model for processing, and obtain the picture emotion information corresponding to the picture information as the target emotion information; through the above steps, after obtaining the user's picture information, input it into the picture emotion detection model in the pre-built detection model, and analyze and process the picture information through the picture emotion detection model, so as to obtain the picture emotion information corresponding to the picture information as the target emotion information. Among them, the construction process of the picture emotion detection model includes: first, using a neural network search algorithm to search for a neural network structure and determine a target neural network model.

[0067] Among them, the neural network search algorithm is preferably an effective neural network architecture search algorithm (Efficient Neural Architecture Search, ENAS), and the ENAS algorithm and the reinforcement learning algorithm are used to construct the neural network structure of the convolution kernel recurrent neural network, so as to determine the target neural network model. In addition, if the user's facial image information is first obtained before the neural network search algorithm is used to search the neural network structure and determine the target neural network model, and then the neural network search algorithm is used to search the neural network structure for the user's facial image information to determine the target neural network model corresponding to the facial image information, in this way, personalized design for the user can be achieved, that is, when the picture information received by the picture emotion detection model generated later does not match the user in the facial image information, the corresponding picture emotion information is not generated, and the emotional feedback voice is not provided for the user who does not match the facial image information. In this way, personalized design can be achieved, which is specially for users who have collected facial image information. If the user's facial image information is not obtained before the neural network search algorithm is used to search the neural network structure and determine the target neural network model, then it is not a personalized design, and everyone can use it, and emotional feedback voice can be provided for everyone who provides picture information. Secondly, a pre-stored sample set of picture information is obtained, wherein the sample set of picture information includes picture information samples and sample picture emotion information corresponding to the picture information samples. The pre-stored sample set of picture information may include a publicly available data set on the Internet, and in this embodiment, also includes pictures and emoticon packages crawled from the Internet according to emoticon tags, and sufficient picture information of specific users obtained in cooperation with relevant technology companies with the user's consent. If the robot using the data interaction method of this embodiment provides services specifically for pregnant women, then the specific user here may be a pregnant woman.

[0068] Finally, according to the first preset iteration rule, the target neural network model is iteratively trained using the image information sample and the sample image emotion information to obtain a maturely trained target neural network model as the image emotion detection model. Among them, the first preset iteration rule in this embodiment can be a set number of iterations, and the training is stopped when the number of iterative training reaches the set number of iterations, or it can be a rule of iterative training until the detection accuracy converges.

[0069] Based on the emotion recognition model, as an improved solution, the electronic ink screen is updated based on the preset pattern image information. First, the system randomly selects one of the m pictures of the user to display, or the user specifies one of the m pictures to display. Then, the picture is replaced and displayed according to the preset pattern. Where m is greater than 1.

[0070] The preset modes include: a first strategy, a second strategy, a third strategy and a fourth strategy; the selecting the preset mode for picture display according to the emotional state of the picture includes: in response to the emotional state of the picture being the positive and happy state, calling the first strategy for picture display; in response to the emotional state of the picture being the negative and depressed state, calling the second strategy for picture display; in response to the emotional state of the picture being the anxious and nervous state, calling the third strategy for picture display; in response to the emotional state of the picture being the angry and annoyed state, calling the fourth strategy for picture display.

[0071] This application can adjust the display mode of the picture according to the mood of the picture, which is more intelligent and adaptable to the specific situation.

[0072] Specifically, in the embodiment, the first strategy, the second strategy, the third strategy and the fourth strategy may be: when a common battery is used as the power source, the power of the power source is obtained as x, the power required for each screen refresh is obtained as y, and when y is greater than or equal to x, a charging reminder is issued. The picture is not changed until y is less than x;

[0073] The fourth strategy is that when y is less than x, the picture emotional state is immediately replaced with a picture with the positive and happy state. If there is no picture with the positive and happy state emotional state, the user is suggested to add more pictures through the mobile phone.

[0074] The third strategy is that when y is less than bx and b is less than 1, the picture emotional state is replaced with a picture of the positive and happy state. If there is no picture of the positive and happy state, the mobile phone is used to suggest the user to add more pictures.

[0075] The second strategy is that when y is less than cx and c is less than 1, the picture emotional state is replaced with a picture of the positive and happy state. If there is no picture of the positive and happy state, the mobile phone suggests the user to add more pictures.

[0076] The first strategy is that when y is less than dx and d is less than 1, the picture is replaced with a picture of a positive and happy emotional state according to the power situation. Specifically, the power of the power supply is obtained as x, and the power required for each screen refresh is obtained as y. The replacement frequency is: when ey is less than x, it is replaced every q hours, where e and q are integers greater than zero, for example, e is 200, 100, 80. q can be 1, 2, or 3.

[0077] When ey is greater than x, and fy is less than x, the replacement is performed every w hours, where e, w, and f are integers greater than zero, for example, e is 200, 100, 80, w can be 5, 6, 7, and f is 20, 10.

[0078] If fy is less than x, the image will not be changed temporarily, for example, f is 20 or 10.

[0079] Specifically, in another possible embodiment, the first strategy, the second strategy, the third strategy and the fourth strategy may be: when a common battery is used as the power source, the power of the power source is obtained as x, the power required for each screen refresh is obtained as y, and when y is greater than or equal to x, a reminder to charge is given. The picture is not changed until y is less than x;

[0080] The fourth strategy is that when y is less than x, the emotional state of the picture is immediately replaced with a picture of a positive and happy state. If there is no picture with an emotional state of a positive and happy state, the cloud is used to store image information, and the cloud and the electronic ink screen are connected in communication, and the cloud and the electronic ink screen can communicate based on wireless. The background template image is a fusion of a background base map, text elements and icon elements. The background base map is an image, and the image information is applied to the background template image to generate a display picture. The text emotion in the text element in the background template image is "neutral".

[0081] Specifically, the method for determining text emotions is: calling a preset text emotion recognition model to process the text to obtain the user text emotions, specifically including: the text emotion recognition model processes the text to score various preset text emotions, wherein the preset text emotions include: "neutral", "angry", "happy", "sad", "confused", "tired", "anxious", "indifferent";

[0082] The third strategy is that when y is less than bx and b is less than 1, the emotional state of the picture is replaced with a picture of the positive and happy state. If there is no picture with the positive and happy emotional state, the cloud is used to store image information, and the cloud and the electronic ink screen are connected in communication, and the cloud and the electronic ink screen can communicate based on wireless. The background template image is a fusion of a background base map, text elements and icon elements. The background base map is an image, and the image information is applied to the background template image to generate a display picture. The text emotion in the text element of the background template image is "happiness".

[0083] Specifically, the method for determining text emotions is: calling a preset text emotion recognition model to process the text to obtain the user text emotions, specifically including: the text emotion recognition model processes the text to score various preset text emotions, wherein the preset text emotions include: "neutral", "angry", "happy", "sad", "confused", "tired", "anxious", "indifferent";

[0084] The second strategy is that when y is less than cx and c is less than 1, the emotional state of the picture is replaced with a picture of the positive and happy state. If there is no picture with the positive and happy emotional state, the cloud is used to store image information, and the cloud and the electronic ink screen are connected in communication, and the cloud and the electronic ink screen can communicate based on wireless. The background template image is a fusion of a background base map, text elements and icon elements. The background base map is an image, and the image information is applied to the background template image to generate a display picture. The text emotion in the text element of the background template image is "happiness".

[0085] Specifically, the method for determining text emotions is: calling a preset text emotion recognition model to process the text to obtain the user text emotions, specifically including: the text emotion recognition model processes the text to score various preset text emotions, wherein the preset text emotions include: "neutral", "angry", "happy", "sad", "confused", "tired", "anxious", "indifferent";

[0086] The first strategy is that when y is less than dx and d is less than 1, the picture is replaced with a picture of a positive and happy emotional state according to the power situation. Specifically, the power of the power supply is obtained as x, and the power required for each screen refresh is obtained as y. The replacement frequency is: when ey is less than x, it is replaced every q hours, where e and q are integers greater than zero, for example, e is 200, 100, 80. q can be 1, 2, or 3.

[0087] When ey is greater than x, and fy is less than x, the replacement is performed every w hours, where e, w, and f are integers greater than zero, for example, e is 200, 100, 80, w can be 5, 6, 7, and f is 20, 10.

[0088] If fy is less than x, the image will not be changed temporarily, for example, f is 20 or 10.

[0089] It should be noted that the cloud is used to store image information, and is also used to receive background editing instructions from users, accept online editing by users on the cloud, and the cloud and the electronic ink screen are connected in communication, and the cloud and the electronic ink screen can communicate wirelessly. The background template image is a fusion of the background base map, text elements and icon elements. The background base map is an image, which can be an image selected by the user. The text elements and icon elements can also be selected by the user at will, and the background template image can be previewed by the user. The image information is a compressed image file. The cloud can store a large number of background template images, and can also store a large amount of image information related to the background template image, and the cloud can convert the background template image into image information supported by the electronic ink screen. There is no need to convert the background template image on the electronic ink screen, thereby reducing the operating pressure of the electronic ink screen and saving the computing power of the electronic ink screen.

[0090] Exemplarily, the cloud obtains the image information by the cloud responding to the user's background editing instruction, obtaining the background template image, and converting the background template image into image information, or the cloud responds to the update request of the electronic ink screen and determines the image information corresponding to the electronic ink screen update request from the image database in the cloud. Furthermore, the method for the electronic ink screen to receive the image information may be to send an update request to the cloud, and the cloud feeds back the image information matching the update request to the electronic ink screen, wherein the update request includes the name of the updated background, and the image information may also have a corresponding image name, and the image name of the image information matching the updated background name is searched in the cloud; the method for the electronic ink screen to receive the image information may also be that the user can trigger the update instruction of the electronic ink screen in the cloud, and the cloud directly sends the image information to the electronic ink screen to instruct the electronic ink screen to update based on the image information.

[0091] This application can adjust the display mode of the picture according to the battery status, and display positive pictures as much as possible, which is conducive to the physical and mental health of the user. And when there are no positive pictures, the image information is applied to the background template image to generate a display picture, and the positive or neutral text information in the background template image is used to make the picture relatively positive, reduce the user's anxiety, and enhance positive emotions.

[0092] Specifically, in another possible embodiment, the first strategy, the second strategy, the third strategy and the fourth strategy may be: when a common battery is used as the power source, the power of the power source is obtained as x, the power required for each screen refresh is obtained as y, and when y is greater than or equal to x, a reminder to charge is given.
