[0033] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0034] Smart home devices have entered thousands of households, such as air conditioners, televisions, washing machines, refrigerators, etc., and many smart home devices have screens that can play screen images such as photos and videos. In the disclosed embodiment, the smart home device with a screen has the function of supporting screen image transmission. In this way, when a smart home device plays a screen image, if it determines that the user has left the effective area, it can transmit the screen image being played to other smart home devices that support screen image transmission and are located to the user, thereby realizing screen image transmission between smart home devices. In this way, no matter how the user moves in the home environment, he can continue to watch the screen image, realizing the experience of watching as he walks, which not only improves the intelligence of the smart home device, but also further improves the intelligence of the home environment.

[0035] Figure 1 FIG. 1 is a schematic diagram of a structure of a screen image transmission system provided by an embodiment of the present disclosure. Figure 1 As shown, the system for screen image transmission includes: two or more smart home devices that support screen image transmission, wherein the smart home device that is playing the screen image that needs to be transmitted is the first smart home device 100, and the smart home device that locates the user and receives the screen image and plays it is the second smart home device 200.

[0036] Each smart home device in the system for screen image transmission can carry a screen, can play screen images such as pictures and videos, and has the function of supporting screen image transmission. They can be devices in a smart home, so each smart home device can communicate.

[0037] The first smart home device 100 that is playing the screen image is configured to send a location request to find the user to other smart home devices that support screen image transmission when it is determined that the user in the effective area has left, and when receiving feedback information of successful positioning, determine one or more smart home devices that send feedback information of successful positioning as second smart home devices, and send the played screen image to the second smart home device;

[0038] The second smart home device 200 is configured to receive a positioning request, generate and send positioning success feedback information after finding the user according to the positioning request, and receive and play the screen image.

[0039] A user is watching a screen image, such as a video or picture, in the action area of ​​a smart home device. The smart home device that plays the screen image is the first smart home device 100. Suddenly, the user leaves the action area of ​​the first smart home device 100. At this time, the first smart home device 100 may send a location request to find the user to other smart home devices that support screen image transmission.

[0040] Among them, in some embodiments, the identification information of the smart home device supporting screen image transmission is saved in each smart home device in the screen image transmission system, and each home device can communicate with each other. In this way, after the user leaves the action area of ​​the first smart home device 100, the first smart home device 100 can send a location request to find the user to other smart home devices supporting screen image transmission based on the saved identification information of the smart home device. Therefore, the first smart home device 100 is also configured to obtain the identification information of the smart home device supporting screen image transmission and save it in the device list; and establish a communication connection with other smart home devices. Of course, the device list saved in each smart home device can be edited and updated in time. In some embodiments, the first smart home device 100 is also configured to notify the smart home device corresponding to each identification information in the device list when the current identification information is added or reduced in the device list. In this way, in the screen image transmission system, a new current smart home device is added, and the current identification information of the current smart home device is added to the device list saved by each smart home device of the system. If used in a screen image transmission system, when a current smart home device is deleted, the current identification information of the current smart home device is also deleted from the device list saved by each smart home device in the system.

[0041] The smart home device that receives the positioning request can search for the user based on the positioning request. In some embodiments, the user search can be performed based on image recognition. That is, the smart home device is configured to start the image acquisition device to obtain the current image information within the effective area when receiving the positioning request; when the current image information matches the user image information carried in the positioning request, it generates and sends feedback information on successful positioning.

[0042] The smart home device that receives the positioning request parses the positioning request, determines the user image information, and performs image recognition after starting the image acquisition device to obtain the current image information in the effective area. If the recognized image includes the user image information, it can be determined that the current image information matches the user image information carried in the positioning request, and a positioning success feedback information can be sent to the first smart home device 100.

[0043] In this way, the first smart home device 100 can receive feedback information on successful positioning. There may be one, two or more smart home devices in the screen image transmission system that can locate the user, that is, feedback information on successful positioning is fed back, that is, the first smart home device 100 can receive one or more feedback information on successful positioning. In some embodiments, the first smart home device 100 can determine each smart home device that sends feedback information on successful positioning as a second smart home device. Alternatively, the first smart home device 100 can determine a smart home device that sends feedback information on successful positioning as a second smart home device based on the angular distance information between the user and the device carried in the feedback information on successful positioning. Alternatively, the first smart home device 100 can randomly determine a smart home device that sends feedback information on successful positioning as a second smart home device.

[0044] Among them, according to the angle distance information between the user and the device carried in the positioning success feedback information, determining a smart home device that sends positioning success feedback information as the second smart home device may include: comparing the distance values ​​in the angle distance information, and determining the smart home device corresponding to the minimum distance value as the second smart home device. Alternatively, preset an angle weight value and a distance weight value, and then, according to the preset angle weight value and the distance weight value, respectively calculate the angle value and the distance value in each angle distance information to obtain a weighted angle distance value, and determine the smart home device corresponding to the minimum weighted angle distance value as the second smart home device.

[0045] Each smart home device in the screen image transmission system can perform user search upon receiving a positioning request, wherein the second smart home device 200 can generate and send positioning success feedback information after finding the user according to the positioning request, and receive and play the screen image.

[0046] It can be seen that each smart home device used in the screen image transmission system can sometimes be the first smart home device and sometimes be the second smart home device. Therefore, each smart home device has the functions of both the first smart home device and the second smart home device.

[0047] In the screen image transmission system, each smart home device can perform screen image transmission.

[0048] Figure 2 FIG. 1 is a flow chart of a method for transmitting screen images provided by an embodiment of the present disclosure. Figure 2 As shown, the process for screen image delivery includes:

[0049] Step 201: When it is determined that the user in the action area of ​​the first smart home device has left, a location request for finding the user is sent to other smart home devices that support screen image transmission.

[0050] In the disclosed embodiment, the smart home device in the screen image playback is a first smart home device. The first smart home device can determine the user in the effective area through human body sensing, face recognition, etc. When it is determined that the user has left, the first smart home device sends a location request to other smart home devices that support screen image transmission to find the user.

[0051] In some embodiments, each smart home device saves the identification information of the smart home device that supports screen image transmission in the device list and can communicate with other smart devices, that is, it also includes: obtaining the identification information of the smart home device that supports screen image transmission and saving it in the device list; establishing a communication connection with other smart home devices.

[0052] In this way, based on the saved device list, a location request for finding the user can be sent to other smart home devices that support screen image transmission.

[0053] Of course, in some embodiments, the saved device list can also be updated in real time, that is, when the current identification information is added or reduced in the device list, the smart home device corresponding to each identification information in the device list is notified. In this way, the system for screen image transmission is updated in real time, ensuring the stability of the system.

[0054] Step 202: when receiving positioning success feedback information, one or more smart home devices that send positioning success feedback information are determined as second smart home devices.

[0055] Among them, the smart home device that receives the positioning request can search for the user according to the positioning request. In some embodiments, the user search can be performed according to image recognition, that is, after the user is found according to the positioning request, the positioning success feedback information is generated and sent, including: when the positioning request is received, the image acquisition device is started to obtain the current image information in the effective area; when the current image information matches the user image information carried in the positioning request, the positioning success feedback information is generated and sent. Of course, if the smart home device fails to find the user, it will not send the positioning success feedback information, that is, it fails to identify the user image information in the current image information, and it will not send the positioning success feedback information.

[0056] The number of smart home devices that receive the positioning request may be one, two, or more, and the number of smart home devices that can find the user may be zero, one, two, or more. In this way, the first smart home device may receive one, two, or more positioning success feedback information. In some embodiments, each smart home device that sends positioning success feedback information may be determined as the second smart home device. Alternatively, a smart home device that sends positioning success feedback information may be determined as the second smart home device based on the angular distance information between the user and the device carried in the positioning success feedback information. Alternatively, a smart home device that sends positioning success feedback information may be randomly determined as the second smart home device.

[0057] Among them, according to the angle distance information between the user and the device carried in the positioning success feedback information, determining a smart home device that sends positioning success feedback information as the second smart home device may include: comparing the distance values ​​in the angle distance information, and determining the smart home device corresponding to the minimum distance value as the second smart home device. Alternatively, preset an angle weight value and a distance weight value, and then, according to the preset angle weight value and the distance weight value, respectively calculate the angle value and the distance value in each angle distance information to obtain a weighted angle distance value, and determine the smart home device corresponding to the minimum weighted angle distance value as the second smart home device.

[0058] Step 203: The played screen image is transmitted to the second smart home device for playback.

[0059] The first smart home device is playing a screen image, and the user is already in the active area of ​​the second smart home device. Therefore, the played screen image can be transmitted to the second smart home device for playback, including: sending one or more of the video, picture and other content, source link, playback progress, etc. to the second smart home device for playback.

[0060] It can be seen that in this embodiment, after the user leaves the effective area of ​​the smart home device that supports screen image transmission, the screen image being played can be transmitted to other smart home devices that support screen image transmission and are located at the user, thereby realizing screen image transmission between smart home devices. In this way, no matter how the user moves in the home environment, he can continue to watch the screen image, realizing a watch-as-you-go experience, which not only improves the intelligence of smart home devices, but also further improves the intelligence of the home environment.

[0061] The operation flow is collected into a specific embodiment below to illustrate the screen image transmission process provided by the embodiment of the present invention.

[0062] In this embodiment, the screen image transmission system can be as follows Figure 1 As shown, it includes: two or more smart home devices that support screen image transmission, wherein the smart home device that is playing the screen image that needs to be transmitted is the first smart home device 100, and the smart home device that locates the user and receives and plays the screen image is the second smart home device 200. Each smart home device stores a device list, which includes identification information of the smart home devices that support screen image transmission, and each smart home device can communicate with each other.

[0063] Figure 3 FIG. 1 is a schematic diagram of a signaling interaction for screen image transmission provided by an embodiment of the present disclosure. Figure 1 , Figure 3 , the process for screen image delivery includes:

[0064] Step 301: The first smart home device in the screen image playback area determines whether the user has left the action area. If so, execute step 302; otherwise, return to step 301.

[0065] The user image information can be obtained through human infrared detection and image recognition, and the user detection can be performed. When it is detected that the user has left, step 302 is executed, otherwise, the process returns to step 301 to continue playing the screen image and performing user detection.

[0066] Step 302: According to the identification information of the smart home devices supporting screen image transmission in the stored device list, the first smart home device sends a location request for finding the user to other smart home devices supporting screen image transmission.

[0067] Step 303: The smart home device that receives the positioning request starts the image acquisition device to obtain the current image information in the effective area and perform image recognition.

[0068] Step 304: The smart home device that determines that the current image information matches the user image information carried in the positioning request generates and sends positioning success feedback information.

[0069] The smart home device that receives the positioning request performs image recognition on the current image information obtained. When the recognized image information includes the user image information carried in the positioning request, it can generate and send successful positioning feedback information. That is, the smart home device that determines that the current image information matches the user image information carried in the positioning request will generate and send successful positioning feedback information.

[0070] Step 305: the first smart home device determines a smart home device that sends a positioning success feedback message as a second smart home device according to the angular distance information between the user and the device carried in the positioning success feedback message.

[0071] Step 306: The first smart home device transmits the played screen image to the second smart home device for playback.

[0072] It can be seen that in this embodiment, when a smart home device plays a screen image, if it determines that the user has left the active area, the screen image being played can be transmitted to other smart home devices that support screen image transmission and are located at the user, thereby realizing screen image transmission between smart home devices. In this way, no matter how the user moves in the home environment, he can continue to watch the screen image, realizing a watch-as-you-go experience, which not only improves the intelligence of smart home devices, but also further improves the intelligence of the home environment.

[0073] According to the above process for screen image transfer, a device for screen image transfer can be constructed.

[0074] Figure 4 Schematic diagram of a device for transmitting screen images provided by an embodiment of the present disclosure. Figure 4 As shown, the device for transferring screen images includes: a sending module 410 , a determining module 420 and a transferring module 430 .

[0075] The sending module 410 is configured to send a location request for finding the user to other smart home devices that support screen image transmission when it is determined that the user in the action area of ​​the first home device has left.

[0076] The determination module 420 is configured to determine one or more smart home devices that send successful positioning feedback information as second smart home devices when receiving successful positioning feedback information, wherein the successful positioning feedback information is generated and sent by the smart home device after finding the user according to the positioning request.

[0077] The transmission module 430 is configured to transmit the played screen image to the second smart home device for playback.

[0078] In some embodiments, it also includes: a communication saving module, which is configured to obtain identification information of smart home devices that support screen image transmission and save it in a device list; and establish a communication connection with other smart home devices.

[0079] In some embodiments, it also includes: an update module configured to notify the smart home device corresponding to each identification information in the device list when the current identification information is added or reduced in the device list.

[0080] In some embodiments, the determination module 420 is specifically configured to determine a smart home device that sends a successful positioning feedback message as a second smart home device based on the angular distance information between the user and the device carried in the successful positioning feedback information; or, to determine each smart home device that sends a successful positioning feedback message as a second smart home device.

[0081] The smart home device used in the screen image transmission system may sometimes be the first smart home device and sometimes be the second smart home device. Therefore, in some embodiments, the screen image transmission device also includes: a collection module and an identification and positioning module.

[0082] The acquisition module is configured to start the image acquisition device to obtain current image information within the effective area when a positioning request is received.

[0083] The identification and positioning module is configured to generate and send positioning success feedback information when the current image information matches the user image information carried in the positioning request.

[0084] Of course, in some embodiments, the device for screen image transmission can receive the screen image and play it.

[0085] The following describes in detail the screen image transmission process of the device for screen image transmission applied to smart home equipment.

[0086] In this embodiment, the smart home device has the function of the first smart home device and also has the function of the second smart home device.

[0087] Figure 5 Schematic diagram of a device for transmitting screen images provided by an embodiment of the present disclosure. Figure 5 As shown, the device for transmitting screen images includes: a sending module 410 , a determining module 420 , a transmitting module 430 , a storing and communicating module 440 , an updating module 450 , a collecting module 460 and an identifying and positioning module 470 .

[0088] The communication saving module 440 obtains the identification information of the smart home device supporting screen image transmission and saves it in the device list; and can establish communication connections with other smart home devices. When the current identification information is added or reduced in the device list, the updating module 450 can notify the smart home device corresponding to each identification information in the device list.

[0089] In this way, when the smart home device is playing the screen image, if it is determined that the user in the effective area has left, the sending module 410 can send a location request for finding the user to other smart home devices that support screen image transmission based on the device list saved in the communication module 440.

[0090] In this way, when receiving the positioning success feedback information, the determination module 420 can determine a smart home device that sends the positioning success feedback information as the second smart home device according to the angular distance information between the user and the device carried in the positioning success feedback information. Thus, the transmission module 430 can transmit the played screen image to the second smart home device for playback.

[0091] If the smart home device receives a positioning request for finding a user, the acquisition module 460 can start the image acquisition device to obtain the current image information within the effective area; and when the current image information matches the user image information carried in the positioning request, the identification and positioning module 470 can generate and send a successful positioning feedback message, so that the smart home device that sent the positioning request can transmit the screen image.

[0092] Of course, the smart home device can play the transmitted screen image after receiving it.

[0093] It can be seen that in this embodiment, the device for screen image transmission can transmit the screen image being played to other smart home devices that support screen image transmission and are located to the user after the user in the effective area leaves, thereby realizing screen image transmission between smart home devices. In this way, no matter how the user moves in the home environment, he can continue to watch the screen image, realizing a watch-as-you-go experience, which not only improves the intelligence of smart home devices, but also further improves the intelligence of the home environment.
