When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0055] Figure 1 This is an application environment diagram of a local area network-based electronic photo frame picture display method provided in one embodiment of the present application. Figure 1 As shown, in the application environment, an electronic photo frame server 10 , an electronic photo frame client 20 and a user mobile terminal 30 are included.

[0056] In this embodiment, the user selects any electronic photo frame as the server 10 and sets a local area network hotspot on the server 10. Other electronic photo frames are respectively connected to the electronic photo frame server 10 as clients 20. The user mobile terminal 30 can be a smart phone, a tablet computer, a laptop computer, a smart watch, etc., but is not limited thereto. The terminal 30 can be connected to the electronic photo frame server 10 through a network and join the local area network of the server 10, thereby controlling the picture display of each electronic photo frame client 20.

[0057] Reference Figure 2 As shown, in one embodiment, a method for displaying pictures in an electronic photo frame based on a local area network is proposed, which specifically includes the following steps.

[0058] Step S102, when executing the boot command, detecting whether the device is configured as a Socket communication server.

[0059] The middle photo part of the electronic photo frame is an LCD screen, which is also equipped with power supply, communication module, storage medium and other components, and can directly display digital photos. Electronic photo frames are usually equipped with a certain capacity of local storage space or support cloud storage services to display photos. The server receives and sends communication requests between the user's mobile terminal and the electronic photo frame client, and serves as a bridge for information transmission. The electronic photo frame client is a picture display device. After connecting to the local area network, it can display pictures according to the user's selection of an electronic photo frame client. After the electronic photo frame is turned on, a startup wizard is provided to guide the user to choose to be a server or client. During the next startup process, it automatically detects whether it is configured as a Socket communication server. The electronic photo frame provides different operations based on the user's selection to prompt the user to proceed to the next step.

[0060] Step S104, when configured as a Socket communication server, receiving connection requests from a Socket communication client and a user mobile terminal, and establishing communication with the client and the user mobile terminal.

[0061] The electronic photo frame device configured as the server receives the connection request sent by the electronic photo frame client device, and continuously monitors the data of the electronic photo frame client, and dynamically adjusts the number of clients connected to the server in real time. The server receives the connection request from the user's mobile terminal (such as a smart phone) and establishes communication. Ensure the stability of data exchange. The communication between the electronic photo frame and the user's mobile terminal can be carried out through the TCP / IP protocol. The communication between the electronic photo frame and the user's mobile terminal in the local area network is based on the socket service.

[0062] Step S106: receiving the photo frame identification information sent by the client and generating a device list of the client according to the photo frame identification information.

[0063] After the client device successfully connects to the server, it will send the photo frame identification information, and the server will receive the photo frame identification information sent by the connected client. The photo frame identification information may include the device name of the client (such as "electronic photo frame"), unique identifier (such as MAC address or device ID) and current device status, etc. After receiving the photo frame identification information, the server records the device information of each client and dynamically generates a device list containing all connected clients in the local area network based on the received photo frame identification information.

[0064] Step S108: sending the device list to the user's mobile terminal.

[0065] After the server generates the device list, it sends it to the connected user mobile terminal (including the control APP). The device list contains the device IDs and basic information of all electronic photo frame clients in the current local area network. Users can view and select the target electronic photo frame client for operation through the APP.

[0066] Step S110, receiving a picture display request from a user's mobile terminal, and determining a target client according to the picture display request to display the user's picture.

[0067] The user selects the target electronic photo frame client through the control APP in the mobile terminal and sends a picture display request to the server. The request contains the target electronic photo frame client ID and relevant information about the picture content to be displayed. After receiving the request, the server parses the target client device ID in the request and transmits the corresponding picture data to the target electronic photo frame client. After the target electronic photo frame client receives the picture data transmitted by the server, it immediately displays the picture content on the device screen to complete the user's picture display operation. Among them, the electronic photo frame server can also be selected as the object of picture display.

[0068] In this embodiment, the user does not need to pre-configure the server role for a certain photo frame. Any device can be selected as the server when the network is initialized, which reduces the complexity of device configuration. The server manages the client connection and data transmission uniformly, ensuring the stability and synchronization of communication between devices. The server dynamically generates a device list based on the photo frame identification information sent by the client, and synchronizes it with the control APP in the user's mobile terminal. The user can intuitively manage and select the target electronic photo frame client. The user can centrally control multiple electronic photo frame clients through the control APP, without having to operate each electronic photo frame client separately, which significantly improves the user experience. For example, in a home scenario, the user has multiple electronic photo frames and a smart phone. When the user starts an electronic photo frame and configures it as a server, other electronic photo frames connect to the server as clients and join the local area network. The mobile phone also connects to the server and starts the control APP. The user can see the device list of all electronic photo frame clients on the APP, select a specific device, and send a picture display request. The selected electronic photo frame client displays the picture immediately after receiving it, and other photo frames keep updating synchronously or display independently.

[0069] Reference Figure 3 As shown, before detecting whether the computer is configured as a Socket communication server when executing the startup command, the following steps are included:

[0070] Step S202: According to the detection result that the wireless network is configured as an access hotspot, the device configures itself as a server.

[0071] When the electronic photo frame is started for the first time or the network configuration is reset, it will determine whether to start the socket service and act as a server based on its own network status (Wi-Fi configuration). If the network status of the electronic photo frame is AP (access hotspot) mode, the electronic photo frame starts the socket service and automatically sets itself as a server, responsible for processing connection requests from other devices in the local area network.

[0072] Step S204: other electronic photo frames configured to access the access hotspot are configured as clients, and the clients are configured to automatically access the server through the socket service.

[0073] If the electronic photo frame is connected to the access hotspot of the electronic photo frame on the server side, the electronic photo frame is configured as a client and is connected to the server side through the Socket service.

[0074] In this embodiment, at least one electronic photo frame is configured as a server; the server receives the photo frame identification information sent by at least one client. At least one server and client are required in the local area network. When a new electronic photo frame is added, it only needs to be determined as a client, or the user mobile terminal only needs to connect to the corresponding WiFi hotspot to automatically join the local area network. Similarly, when a new user mobile terminal needs to join the local area network, it only needs to connect the new user mobile terminal to the corresponding local area network hotspot to join the local area network.

[0075] Reference Figure 4 As shown, in one embodiment, receiving a connection request between a Socket communication client and a user mobile terminal, and establishing communication with the client and the user mobile terminal includes:

[0076] Step S302, when the photo frame application software of the user's mobile terminal is started, it automatically connects to the server by accessing the hotspot.

[0077] When the user's mobile terminal is connected to the corresponding hotspot and the photo frame application software (control APP) configured with the photo frame is started, the control APP will also actively connect to the server in the local area network.

[0078] Step S304: Send a data packet containing user identity information to the server.

[0079] After the user's mobile terminal is successfully connected, it will send a data packet to the server to tell the server that it is the control APP.

[0080] In this embodiment, the control APP automatically generates a data packet containing user identity information while initiating a connection request. The data packet includes the user device type (such as "mobile terminal"), user ID (such as mobile phone number or device identification) and verification token, etc. The data packet is sent to the server through the socket service. After receiving the data packet, the server decrypts and verifies the user identity information. After the verification is passed, the server formally establishes a communication channel with the user's mobile terminal to provide support for subsequent operations. Exemplarily, the user's smartphone accesses the server access hotspot, the user starts the control APP, the APP automatically scans the local area network, finds the server, and the APP sends a connection request to the server through the socket service, and at the same time sends a data packet containing user identity information (such as: user type "mobile terminal", user ID "U12345", verification token "abcde12345"). Through the transmission and verification of the data packet of user identity information, it is ensured that the server only establishes communication with authorized mobile terminals, thereby improving the security of the system. The server can simultaneously process connection requests from multiple clients and mobile terminals, providing users with the ability to centrally manage devices in the local area network.

[0081] Reference Figure 5 As shown, in one embodiment, receiving the photo frame identification information sent by the client and generating a device list of the client according to the photo frame identification information includes:

[0082] S402: Receive photo frame identification information and decrypt the photo frame identification information.

[0083] The electronic photo frame client will send a locally encrypted photo frame identification information to the electronic photo frame server. After receiving the photo frame identification information, the electronic photo frame server will first decrypt it. The encryption algorithm uses a private symmetric encryption algorithm, uses the hotspot password set by the user as the original encryption key, and processes the password into the actual encryption key using the same algorithm on the server and client. The key is used for data processing during encryption and decryption.

[0084] S404: Determine the client device type and device ID according to the photo frame identification information, and generate association information between the client device type and the client device ID.

[0085] After decryption, the electronic photo frame server can obtain the complete electronic photo frame client information, including the client identifier, SN address and MAC address, so as to determine the client device type and device ID. Based on the device type and device ID determined by the server, the server generates an associated information record of the client device. The associated information record includes: the type of client device (such as "electronic photo frame"); device ID (such as SN address, MAC address); and other possible extended information (such as device name).

[0086] S406: Generate an identification list of the client based on the associated information.

[0087] The server integrates the generated association information into a client identification list. The client identification list contains the type, device ID and associated information of all connected client devices in the current local area network. Exemplarily, the structure of the identification list is as follows:

[0088]

[0089] In this embodiment, the transmission and decryption process of the photo frame identification information adopts a private encryption algorithm to ensure data security and prevent the photo frame identification information from being intercepted or tampered with. By generating the association between the device type and the device ID, the server can quickly and accurately identify all client devices in the local area network. The identification list can be dynamically updated to adapt to the access and disconnection operations of the device, ensuring the real-time and accuracy of device management. The identification list can be further expanded to facilitate the addition of more device information or attributes to support complex multi-device management scenarios.

[0090] Reference Figure 6 In one embodiment, before executing sending the device list to the user mobile terminal, the method includes:

[0091] Step S502: receiving a connection request from a user's mobile terminal and establishing communication through a socket service.

[0092] The user's mobile terminal (such as a smart phone) accesses the LAN hotspot created by the electronic photo frame server; the user starts the control APP in the mobile terminal, and the APP automatically sends a connection request to the electronic photo frame server through the socket service. After the electronic photo frame server monitors the connection request from the user's mobile terminal, it establishes a communication channel to ensure real-time interaction between the user's mobile terminal and the electronic photo frame server.

[0093] Step S504: receiving the encrypted control data sent by the user's mobile terminal, decrypting the control data, and determining the device type of the user's mobile terminal.

[0094] After the user's mobile terminal successfully establishes communication, the user's mobile terminal sends a data packet containing encrypted control data to the electronic photo frame server through the control APP in the terminal; the electronic photo frame server receives the encrypted control data and decrypts it through a preset decryption algorithm or key; the decrypted control data contains the device type information of the user's mobile terminal (for example, "control terminal"). The electronic photo frame server extracts the device type information of the user's mobile terminal based on the decryption result; if the device type information is "control terminal" (i.e., control APP), the electronic photo frame server determines that the terminal has the authority to manage and operate the electronic photo frame device in the local area network.

[0095] Step S506: Based on the device type of the user's mobile terminal, the device list is sent to the user's mobile terminal.

[0096] The electronic photo frame server selects to transmit a device list to the user's mobile terminal according to the device type of the user's mobile terminal. The device list contains the frame identification information of all electronic photo frame clients connected to the server, such as device type, device ID (SN address or MAC address) and its associated information; the server packages the device list and sends it to the user's mobile terminal through Socket communication, and controls the APP to parse and display the device list for the user to select and operate.

[0097] In this embodiment, the electronic photo frame server and the user's mobile terminal establish a reliable communication channel through the socket service to ensure the real-time and stability of information transmission between the two. Control data is transmitted and decrypted through encryption to prevent unauthorized terminals from accessing and operating LAN devices. The device list is presented in the form of a human-computer interactive interface, which is convenient for users to view and select target devices for operation, thereby improving ease of use.

[0098] Reference Figure 7 As shown, in one embodiment, receiving a picture display request from a user mobile terminal, and determining a target client according to the picture display request to display the user picture, includes:

[0099] Step S602: receiving a global configuration instruction sent by a user mobile terminal.

[0100] The user can set the global configuration in the control APP in the mobile terminal, and the control APP will send a global configuration instruction to the electronic photo frame server.

[0101] Step S604: According to the client tag information in the global configuration instruction, the client identifier presented on the user mobile terminal interface is configured to be the same as the client.

[0102] In this embodiment, the global configuration instruction may include a client photo display instruction, a photo hiding instruction, a client photo frame identification information content change instruction, etc. After modification, the client photo frame identification information is also updated synchronously, and the changed content is synchronously presented on the user mobile terminal interface through the device list. It is convenient for users to change the client used to present photos. Exemplarily, the user can add "living room" information to the photo frame identification information of the electronic photo frame client in the living room through the global configuration instruction. The client automatically sends the changed photo frame identification information to the server, and the server updates the device list. The device list is synchronously displayed on the user's mobile terminal, which is convenient for users to configure the displayed pictures or adjust the pictures to improve the user experience.

[0103] Reference Figure 8As shown, in one embodiment, according to the client tag information in the global configuration instruction, configuring the client identifier presented on the user mobile terminal interface to be the same as the client includes:

[0104] Step S702, sending the color configuration instruction in the global configuration instruction to the corresponding client, and generating a color identification of the client;

[0105] Step S704: sending the color identification of the client to the user's mobile terminal, and configuring the client's color identification on the user's mobile terminal interface to be the same as that of the client.

[0106] In this embodiment, the electronic photo frame server adds the color displayed by each electronic photo frame client to the frame identification information of each electronic photo frame client and updates it in the device list. At this time, the user mobile terminal synchronously updates the device list. Different electronic photo frame clients in the device list present different colors, so that the user can intuitively select the corresponding electronic photo frame client by color. The user can also select a single electronic photo frame client to modify the color.

[0107] Reference Fig. 9 As shown, in one embodiment, receiving a picture display request from a user mobile terminal, and determining a target client according to the picture display request to display the user picture includes:

[0108] Step S802, receiving a data packet sent by a user's mobile terminal; the data packet includes an encrypted image;

[0109] Step S804, identifying the data packet and forwarding the data packet to the corresponding photo frame, so that the photo frame can decrypt and display the picture.

[0110] In this embodiment, illustratively, when a user sends a picture to the electronic photo frame client A on a mobile phone, the mobile phone control APP will first encrypt the picture data when loading the picture, and then encapsulate the encrypted content into a data packet and send it to the electronic photo frame server. The electronic photo frame server recognizes that the data packet is an encrypted and packaged picture, and requires it to be handed over to the electronic photo frame client A for display. The electronic photo frame server directly forwards it to the electronic photo frame server A. After receiving the data packet, the electronic photo frame server A determines that this is the content that needs to be displayed, and then starts to decrypt the encrypted data packet using the key. After the decryption is completed, the picture is displayed on the screen, and the encrypted content is saved locally. The electronic photo frame server is responsible for identifying the user operation type and forwarding it, but is not responsible for decrypting the data content that needs to be forwarded. Only when the control app requires the electronic photo frame server to display the content, the electronic photo frame server determines that the data needs to be decrypted and displayed by itself will it perform the decryption and display operation.
