Description

Technical Field

[0001] This invention relates to the field of control systems for smart gateways, smart central control systems, and smart homes, and particularly to the field of smart control products for scenarios such as homes and hotels. Specifically, it refers to a method, device, processor, and computer-readable storage medium for realizing visualized smart home control based on distributed systems. Background Technology

[0002] Currently, the visual control of smart homes is basically based on a central control screen or tablet computer. Each central control screen is an independent entity that connects to a cloud platform via wired or Wi-Fi network. It obtains the status information of smart home devices from the platform and issues control commands through touch screen operation or voice commands.

[0003] This topology, where the gateway and central control screen are each connected to their respective platforms, results in a broken communication link during network outages (i.e., when there is no external network), causing the smart device control to fail. Each central control screen requires independent platform authorization, which is resource-intensive and leads to higher overall costs.

[0004] Tablet computers control devices only through the installation of apps. They are not proprietary central control devices, have low customization for smart home control, their size does not match the wall panel, they lack rich external control interfaces, and are less convenient to use than central control screens. They also have poor user interaction flexibility and higher unit cost. Summary of the Invention

[0030] The present invention provides a device for distributed visualization and smart home control, wherein the device comprises: A processor is configured to execute computer-executable instructions; The memory stores one or more computer-executable instructions, which, when executed by the processor, implement the various steps of the above-described method for distributed visualization and smart home control.

[0032] The computer-readable storage medium of the present invention stores a computer program thereon, which can be executed by a processor to implement the various steps of the above-described method for distributed visualization and smart home control.

[0033] In a specific embodiment of this invention, a distributed visual smart home control method is disclosed. The central control screen displays real-time visual information about rooms, devices, and scenes for status monitoring and control, enabling both online and offline dual-scenario control of the smart home system. The system is highly customizable, easy to maintain, and reduces external data transmission, thus enhancing security.

[0034] Figure 1 This is a schematic diagram illustrating an application scenario provided in an embodiment of this application. Users can construct a communication topology using a wireless router, gateway, central control screen, functional sub-devices, and cloud platform. Figure 1 In the application scenario shown, the gateway and central control screen are connected to a local area network (LAN) built by a router. The gateway and central control screen can access the LAN via wired or Wi-Fi networks. Zigbee / BLE functional sub-devices are connected to the LAN through the gateway. Within the LAN, the gateway configures its own hostname based on the hostname and port number stored in its proprietary protocol. The central control screen enables the gateway's device discovery service, finds the specified hostname, and the two establish communication to obtain the device's IP address and related information. Both parties establish their own message publishing and subscription service frameworks and maintain the normal operation of the message channel. Based on information synchronization and control command issuance needs, both parties publish and subscribe to message commands through the proprietary protocol to complete communication. Both parties publish message commands according to actual operational needs. The gateway can receive control information sent by the central control screen via touch or voice commands and convert it into control commands to send to the functional sub-devices, thus controlling the functional sub-devices. The central control screen can receive device status information from the gateway and update the device status on the screen.

[0035] For specific implementation details, please refer to the following examples.

[0036] Figure 2 A flowchart of a distributed, visualized smart home control method provided in this application embodiment is shown below. Figure 2 As shown, the method includes steps S20, S21, S22, and S23.

[0037] In step S20, the gateway and the central control screen are connected to the local area network. The gateway is configured with a hostname, the central control screen enables the gateway device discovery service, finds the specified hostname, and the two establish communication to obtain the device IP address and related information.

[0038] In this application, the local area network (LAN) can be constructed by network devices such as wireless routers and access points (APs), and the gateway and central control screen can be connected to the LAN via either a wired network or a Wi-Fi network.

[0039] The gateway initiates a discovery service using a hostname defined by a private protocol, broadcasting messages across the local area network (LAN). These messages include information such as the name and service type. The central control panel can then initiate a service discovery process, listen for these broadcast messages on the LAN, and search for the agreed-upon hostname.

[0040] Once the central control screen finds the gateway with the specified hostname, it starts the service resolution process to obtain the IP address of the target gateway and informs the gateway of its own IP address. When both parties know each other's IP address, the device discovery process can be considered complete. In a local area network, the IP address is unique, and thus communication within the local area network can be established.

[0041] According to the example implementation, once the gateway and the central control screen obtain each other's device IP addresses in the local area network, they can establish communication and then switch to the publish and subscribe phase of the message service.

[0042] In step S21, both parties establish their own message publishing and subscription service frameworks.

[0043] The gateway and the central control screen each send messages to each other and subscribe to each other's messages to achieve message synchronization.

[0044] The messages published by the gateway can include topology room information, device status information, scene information, etc. The messages published by the central control screen can include touchscreen operation commands, voice control operation commands, etc.

[0045] When the gateway and the central control screen publish messages, they also subscribe to each other's service information in real time. This can be done through a message channel. The two parties can build many message channels for the transmission of different information.

[0046] To ensure the normal operation of the message channel between the gateway and the central control screen, the central control screen also requires the gateway to subscribe to a keep-alive feature signal, which can be used to confirm the normality of the message channel between the two through periodic heartbeat packets.

[0047] According to the embodiment, after the gateway and the central control screen have completed the establishment of the channel for message publishing and subscription, specific instructions can be issued.

[0048] In step S22, both parties publish and subscribe to message commands based on information synchronization requirements and control command issuance requirements.

[0049] Information synchronization refers to information published by the gateway and subscribed to by the central control screen. This information can include the gateway's heartbeat information and the status information of functional sub-devices, such as the on / off status of switches, the opening and closing status of curtains, and the temperature of air conditioners. This information is synchronized to the central control screen and displayed visually on the screen, making it easier for users to know and control the devices according to their status. Compared with traditional indicator light displays, this is more centralized and convenient.

[0050] Control commands are issued by the central control screen and subscribed to by the gateway. This information can be used for direct user control of devices and scenes via a visual interface on the touchscreen, or as control commands issued via voice. Examples include commands to turn on a switch, open the curtains, or turn on the air conditioner.

[0051] According to the embodiment, the gateway can synchronize the room, device, and scene status of the smart home system to the central control screen, which then displays the information visually. The central control screen can also send device and scene control commands to the gateway through a visual interface and voice commands, thus establishing a synchronization and control path for smart home information based on a local area network.

[0052] In step S23, the gateway and the central control screen issue message instructions according to actual operational needs, and complete the distribution of device control instructions based on the subscribed messages.

[0053] When the status of a functional sub-device changes, it will be transmitted to the gateway via Zigbee / BLE signals. The gateway will then publish the message through the local area network and synchronize it to the central control screen. After subscribing to this information, the central control screen will change the device status on its screen.

[0054] Users issue control commands via touch or voice on the central control screen. The central control screen then publishes the control information within the local area network. The gateway subscribes to this information and, depending on whether there is an external network connection, completes online and offline control of functional sub-devices or scenarios.

[0055] This application utilizes a discovery and message communication method built within a local area network (LAN) by a gateway and a central control screen. This enables local network communication between the two without requiring a cloud connection, allowing the central control screen to control smart home devices offline. Local central control screens can be added or removed at will, directly interacting with the gateway without needing to register device information on the platform. This expands the application scenarios and flexibility of the smart home system, while reducing overall solution costs. Users can flexibly increase the number of central control screens as needed, achieving rapid automatic connection and distributed control, thus enhancing the user experience.

[0056] According to some embodiments, reference Figure 3 Step S20 can be achieved through steps S201, S202, S203, S204, S205, S206, S207, and S208.

[0057] In step S201, the gateway and the central control screen are connected to the same local area network, mainly to ensure that both are on the same network segment, and can be connected via wired network or Wi-Fi network.

[0058] According to the example embodiment, the gateway and central control screen can have their IP addresses assigned directly by the router via DHCP, or they can be manually configured with IP addresses. However, it is not necessary to set specific IP addresses, as long as they are on the same network segment as the router. This application's device discovery does not rely on specific IP addresses, reducing the complexity of construction.

[0059] In steps S202 and S203, the gateway configures the network hostname and network port number, starts the discovery service process, and prepares to be discovered by the central control screen. Simultaneously, it sends a message containing the hostname, IP address, and other information to the broadcast address, broadcasting a message to all devices within the local area network, declaring its identity and IP address.

[0060] In step S204, the central control screen starts the service discovery process, receives broadcast messages, and searches for devices with specific hostnames and port numbers in the local area network. Because it is a broadcast message, all devices in the local area network can receive it.

[0061] In step S205, the central control screen obtains the broadcast message of the gateway hostname, and then starts the service resolution process to obtain the IP address of the target gateway.

[0062] In steps S206 and S207, after obtaining the gateway IP address, the central control screen can send its own IP address to the gateway IP address via the local area network.

[0063] Once both parties know each other's IP address in step S208, the device discovery process can be considered complete. Since IP addresses are unique within a local area network, communication within the local area network can be established.

[0064] According to some embodiments, reference Figure 4 Step S21 can be achieved through steps S211, S212, S213, S214, S215, S216, S217, S218, and S219.

[0065] In step S211, both the gateway and the central control screen have obtained each other's IP addresses, allowing them to establish a device information and command information synchronization service based on the network addresses. This service allows the gateway to act as a message forwarding intermediary, and the gateway and the central control screen can publish and subscribe to messages to each other, thus constructing an information synchronization method.

[0066] As described in S211, in step S212, the gateway, acting as the message forwarding center in the local area network, establishes a message broker service to forward messages sent by the gateway and the central control screen to the target device.

[0067] As described in S211, in steps S213 and S214, the gateway establishes a status information publishing service for the smart home system based on the local area network, and the central control screen establishes a status information subscription service for the smart home system based on the local area network. The central control screen can obtain the device status information sent by the gateway in real time, such as the switch status, the on / off status and brightness of the lights, the temperature and fan speed of the air conditioner, etc.

[0068] As described in S211, in steps S215 and S216, the central control screen establishes a publishing service for control information in the smart home system based on the local area network, and the gateway establishes a subscription service for control information in the smart home system based on the local area network. The gateway can obtain control information issued by the central control side through the touch screen or voice commands in real time. Based on this distributed central control screen architecture, the commands can be issued by any central control screen in the system.

[0069] In steps S217 to S219, considering that the gateway and the central control screen need to interact with each other in real time and that the information channel between them needs to be kept normal at all times, the gateway establishes a keep-alive characteristic signal publishing service with the central control screen based on the local area network, and the central control screen establishes a keep-alive characteristic signal subscription service with the gateway based on the local area network. The central control screen periodically checks the keep-alive characteristic signal of the gateway to determine whether the communication with the gateway is normal. If it is normal, communication is carried out; if it is abnormal, the abnormal handling process is followed.

[0070] According to some embodiments, reference Figure 7 S219 can be achieved through steps S2191, S2192, S2193, and S2194.

[0071] In step S2191, the gateway and the central control screen have established a communication link and subscribed to message services for each other. The two parties can synchronize the device status information, control command information and keep-alive characteristic signal information.

[0072] In step S2192, the central control screen receives the gateway's keep-alive characteristic signal at specific periodic intervals, indicating that communication between the two is normal and message publishing and subscription status is maintained. Each central control screen in the system receives the gateway's keep-alive characteristic signal to ensure that each link is normal.

[0073] In step S2193, if any central control screen does not receive the gateway keep-alive feature signal at a specific interval, it indicates that the communication between the two is abnormal. The central control screen then re-establishes the device information and command information synchronization service based on the network address.

[0074] In step S2194, the central control screen re-establishes the device information and command information synchronization service and then reconnects to the gateway. If it still fails after a specified number of attempts, a timeout is determined, and the user is reminded to manually handle the connection problem. Relevant information will be displayed on the screen. Based on the distributed topology, each central control screen is responsible for its own link with the gateway, and a problem with one central control screen will not cause other central control screens to malfunction.

[0075] According to some embodiments, reference Figure 5 Step S22 can be achieved through steps S221, S222, S223, S224, S225, S226, S227, and S228.

[0076] In steps S221 and S222, the gateway publishes room information from the smart home system via the local area network (LAN), and the central control screen subscribes to this room information via the LAN and displays it on the screen. Each central control screen can obtain all room information, and the user can then select the room to display on the screen according to their needs.

[0077] In steps S223 and S224, the gateway publishes smart device status information based on the local area network (LAN), and the central control screen subscribes to the smart device status information based on the LAN and visualizes the information on the screen. Each central control screen can obtain all device status information.

[0078] In steps S225 and S226, the gateway publishes the established scene information based on the local area network (LAN), and the central control screen subscribes to the established scene information based on the LAN, and visualizes the information on the screen. Each central control screen can obtain all the scene information, and the user can then select the scene to be displayed on the screen according to their needs.

[0079] In step S227, the central control screen publishes control information generated by the touchscreen operation based on the local area network, including device function points and scenarios. For example, signals for controlling the opening and closing of switches, adjusting the color of lights, opening and closing of curtains, adjusting the temperature of air conditioning, and execution control commands for some scenarios.

[0080] In step S228, the central control screen issues control information generated by voice commands via the local area network, including device functions and scenarios. The specific operation content is similar to that mentioned in S227, except that this step uses information issued via voice commands.

[0081] In step S229, the gateway subscribes to device and scene control information issued by the central control screen via touch screen or voice control commands based on the local area network.

[0082] The specific control method of the gateway over the device described in S23, according to some embodiments, refers to... Figure 6Step S23 can be achieved through steps S231, S232, S233, S234, S235, and S236.

[0083] In step S231, the gateway stores device and scene control information in its local storage chip and synchronizes the latest information when there are device or scene adjustments. The local storage chip can be a storage chip such as Nor Flash / Nand Flash / eMMC in the gateway system, used to store device firmware and user data. The device and scene control information is part of the user data, and this information can be read and written through the gateway's main chip and can be updated to the latest status in real time.

[0084] In step S232, the gateway subscribes to device and scene control information issued by the central control screen via touch screen or voice control commands based on the local area network, for use in subsequent command sending.

[0085] In steps S233 and S234, if the external network is normally connected, the gateway forwards the control message to the platform. The platform receives the control command and issues specific control command information to the gateway according to the control logic. When there is an external network connection, overall control is performed through the platform. After receiving the platform's control command, the gateway sends the control command to the specific functional sub-device to complete the control operation.

[0086] If the external network is down in steps S235 and S236, the gateway will directly retrieve the device and scene information and control logic stored in the local ROM to perform local control analysis. After the gateway derives the control command based on the local information, it will send the control command to the specific functional sub-device to complete the control operation.

[0087] This invention discloses a series of methods for gateways and central control screens to discover each other in a local area network, establish message subscriptions, establish keep-alive mechanisms, and establish online / offline control processes. It provides more specific methods for message publishing and subscription to complete communication, and offers concrete methods for establishing and implementing communication.

[0088] The distributed system of this invention refers to the ability of the central control screen, which acts as a gateway display and feedback device, to be flexibly deployed in space. Each central control screen communicates independently with the gateway and does not rely on the cloud. Each screen can obtain information from the gateway and send control commands to the gateway. The overall function will not be abnormal due to the problem of one screen. Central control screens can also be added flexibly at any time.

[0098] This invention employs a method, apparatus, processor, and computer-readable storage medium for distributed, visualized smart home control. The gateway and central control screen can connect not only to the platform but also via a local proprietary protocol, enabling local network communication without cloud access. This allows for offline control of the smart home system from the central control screen. Local central control screens can be added or removed at will, directly interacting with the gateway without requiring registration of device information on the platform. This expands the application scenarios and flexibility of the smart home system while reducing overall system costs. Users can flexibly increase the number of central control screens as needed, achieving rapid automatic connection and distributed control, thus enhancing the user experience. This provides a low-cost, high-efficiency control method for smart homes, improving the product's market competitiveness.
