Description

Technical Field

[0001] This invention relates to the field of smart home control technology, and more specifically, to a unified control method and device for smart home devices. Background Technology

[0002] With the rapid development of IoT technology, smart homes have gradually become an indispensable part of modern families. Through various sensors and smart devices, home environments can become more comfortable, safer, and more energy-efficient. However, the smart home industry suffers from severe fragmentation. Devices from different brands and ecosystems often use different communication protocols, such as Zigbee, Bluetooth, Wi-Fi, and Z-Wave, making interoperability and unified control between devices a major challenge.

[0003] Current smart home solutions, such as multi-protocol gateways and ecosystem interconnection systems, while addressing communication compatibility between devices to some extent, have significant limitations. Multi-protocol gateways typically require the integration of multiple communication modules to control devices using different protocols, but user device control remains confined to brand-specific apps or cloud platforms. While seamless connectivity within a single ecosystem is possible, cross-ecosystem device collaboration remains challenging, requiring users to manage multiple entry points, resulting in a fragmented user experience and hindering truly unified smart home control.

[0004] Furthermore, the control logic of existing smart home solutions heavily relies on cloud servers. Whether it's protocol conversion, data relay, or the execution of automated scenarios, a stable network connection is essential. Once the home network or cloud services are interrupted, device control will essentially fail, resulting not only in a degraded user experience but also in core home functions such as lighting and security systems, which may malfunction due to network issues, posing security risks. While some solutions utilize cloud servers for protocol conversion and data relay to achieve a degree of compatibility, this method has a significant weakness in network dependence, failing to guarantee system reliability and responsiveness during network outages.

[0005] Furthermore, existing technologies offer relatively rudimentary device access management, lacking fine-grained access control for multiple users, roles, and scenarios within a home. For instance, simple device sharing may not suffice when family members, tenants, or visitors need to use smart devices, especially regarding privacy protection and the delineation of device control permissions. Traditional smart home platforms struggle to grant device function levels to different user roles, which is particularly crucial in home role management and rental scenarios. Moreover, inadequate access management can lead to risks of privacy breaches and unauthorized access, impacting the security of the smart home system and user trust.

[0006] There is currently no effective solution to the above problems. Summary of the Invention

[0040] Example 1

[0041] According to an embodiment of the present invention, a method embodiment of a unified control method for smart home devices is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0042] Figure 2 This is a flowchart of a unified control method for smart home devices according to an embodiment of the present invention, such as... Figure 2As shown, the method includes the following steps:

[0043] Step S202: Receive raw device communication data from smart home devices using different wireless communication protocols via an integrated multi-mode communication chipset. The multi-mode communication chipset is a hardware component in the smart home system that integrates multiple wireless communication function modules. The smart home system includes smart home devices.

[0044] In this embodiment, integrating multiple communication chips is merely the hardware foundation. This embodiment achieves complete decoupling between protocols and applications through a "protocol-independent architecture," rather than simply stacking hardware. Compared to existing technologies, this is the first time that a unified data model (UDM) and a dynamic protocol-driven hot-swappable mechanism are used within the gateway to shield private protocol differences, freeing application developers from concern for the underlying protocols and significantly reducing development complexity. This hardware-software co-design transcends conventional thinking in the field.

[0045] This method leverages the versatility of multi-mode communication chipsets, which integrate various wireless communication technologies such as Zigbee, Bluetooth Mesh, and Wi-Fi, enabling the reception and processing of signals from different protocols on a single hardware platform. When smart home devices send signals, the corresponding modules of the chipset (antenna, demodulator, and protocol parser) identify and parse these signals, converting them into data formats that the system can understand, thereby achieving information collection and interconnection between multi-protocol devices.

[0046] By implementing this control method, the compatibility and responsiveness of the smart home system are significantly enhanced. The integration of a multi-mode communication chipset enables the smart home gateway to seamlessly receive and process data from devices of different brands and protocols, greatly expanding the system's device access capabilities and freeing it from the limitations of a single communication standard, providing users with a comprehensive smart home network. Simultaneously, by optimizing the signal reception and parsing process, high-efficiency and low-latency data transmission is ensured. Even in environments with dense devices or signal interference, accurate data capture and timely processing are guaranteed, improving the immediacy of user operation and the overall robustness of the system.

[0047] Step S204: Parse the original device communication data using a protocol identification algorithm to obtain device parsed data.

[0048] In this embodiment, the core of the system employs a dynamic protocol identification algorithm for the identification and access of multi-protocol devices. This dynamic protocol identification algorithm is not simply a matter of applying existing technologies; its innovation lies in combining cosine similarity calculation (threshold > 0.92) with real-time interaction with a cloud-based protocol library.

[0049] In this method, the raw device communication data packets received by the gateway contain specific protocol characteristics, such as header information, vendor ID, and data format. The protocol identification algorithm uses these characteristics to compare and match them with pre-stored protocol templates, employing methods such as cosine similarity calculation to determine the protocol of the received data packet. Once the specific protocol is identified, the algorithm further parses the payload in the data packet, extracting protocol-specific instructions, parameters, and status information to form device parsing data, preparing for subsequent protocol conversion and instruction execution.

[0050] By implementing this control method, the device access and protocol compatibility capabilities of the smart gateway are greatly enhanced. Through precise protocol identification, the gateway can quickly and accurately parse the communication data of various devices, regardless of whether the devices use different protocols such as Zigbee, Bluetooth Mesh, or Wi-Fi. This means that users can connect smart home devices of different brands and protocols to the system and enjoy a unified control experience without complex settings or reliance on specific brand apps. Simultaneously, the generation of device-parsed data provides accurate foundational information for subsequent protocol conversion and unified data model mapping, ensuring that device commands are correctly understood and executed, thereby improving the overall operational efficiency and user experience of the smart home system.

[0051] Step S206: Select the target protocol parsing plugin from the cloud protocol library based on the device parsing data.

[0052] In this embodiment, after the new device is powered on, the bridging box continuously scans broadcast packets across various frequency bands. It extracts feature codes using multiple characteristic fields such as "vendor ID, message length, and checksum," and relies on a cloud library of over 100 pre-stored protocol templates for matching, achieving automatic identification and adaptation of the new device. This identification mechanism based on a dynamic protocol library significantly improves compatibility and scalability compared to static matching methods.

[0053] In this method, after the gateway parses the raw communication data using a protocol identification algorithm, it uploads key parameters from the parsed data (such as manufacturer ID, device type, protocol version, etc.) to a cloud server. The cloud server then possesses a vast library of protocol parsing plugins, containing dedicated parsing scripts or drivers for numerous smart home brands and devices. Based on the parameters in the received device parsing data, the server queries the protocol library to find the most suitable target protocol parsing plugin and pushes it to the smart gateway.

[0054] By implementing this control method, the smart gateway gains the ability to dynamically adapt to and learn new devices, significantly improving the system's flexibility and scalability. This on-demand acquisition of protocol parsing plugins means that whenever a new smart home device joins the system, the gateway does not need to pre-install all possible protocol parsing programs. Instead, it can download the necessary plugins from a cloud library in real time to identify and control the new device. This approach not only reduces the cost and complexity of the gateway hardware but also enables the system to continuously evolve as new devices and protocols emerge in the market, maintaining its cutting-edge nature and competitiveness.

[0055] Step S208: After selecting the target protocol parsing plugin, store the target protocol parsing plugin in the local storage of the smart home system's gateway.

[0056] In this embodiment, security authentication is performed through two-way authentication. The device requires physical button confirmation and digital certificate signing (using the ECDSA algorithm of the ATECC608B security chip) to prevent unauthorized access.

[0057] This method is based on the concepts of distributed computing and edge storage, utilizing the local storage resources of the smart gateway to cache necessary protocol parsing logic. Once the gateway successfully identifies and matches a specific smart home device protocol, it requests the corresponding protocol parsing plugin from the cloud server. The plugin is transmitted in the form of binary code or a configuration script. After receiving the plugin, the gateway stores it in local non-volatile memory, such as flash memory or a hard drive, so that it can be directly accessed in subsequent device communications without needing to retrieve it from the cloud again.

[0058] By implementing this control method, the response speed and stability of the smart home system are significantly improved. Because the protocol parsing plugin is stored internally in the gateway, it can directly call the local plugin for data parsing and command conversion when processing device communication, avoiding network transmission delays and potential connection instability risks. Even in the event of a network outage or poor network conditions, the gateway can continue to use the downloaded plugin to control and manage connected smart home devices, ensuring the smooth execution of automation scenarios and user control commands.

[0059] Step S210: Process the original device communication data using the target protocol parsing plugin to obtain the current device status of the smart home, and / or encode the control commands using the target protocol parsing plugin to obtain target control commands that the smart home devices can recognize.

[0060] In this embodiment, for protocol conversion and data unification, the system defines a Unified Data Model (UDM) as an intermediate language: all device commands are mapped to a standardized JSON format. The conversion process employs a differential compression algorithm (bsdiff), optimized for the data characteristics of smart home devices, transmitting only the changed data and saving bandwidth.

[0061] For example, {"dev_id":"light_01","action":"set_brightness","value":80}) achieves semantic conversion through field-level mapping rules (such as converting the "brightness" field of the Mi Home protocol to the "light_level" field of the Huawei HiLink protocol).

[0062] In this method, when the gateway receives raw communication data from the device, it calls the corresponding plugin stored locally to interpret the information in the data packet according to the specific protocol specifications used by the device, and extract the device's real-time status (such as the brightness of lights, the temperature setting of air conditioners, etc.). Similarly, when the user issues control commands through a smart home application or voice assistant, the gateway also uses the same plugin to convert general control intentions into control commands that conform to the specific device protocol, ensuring that the commands can be accurately received and executed by the device.

[0063] By implementing this control method, device status transparency and precise transmission of control commands are achieved, greatly enhancing the intelligence level and user experience of the entire smart home system. First, real-time device status monitoring allows users to understand the status of various facilities in their home at any time, making it more intuitive and convenient to view information through a mobile app or set automation scenes. Second, accurate encoding of control commands ensures that user intentions are correctly understood and executed by smart home devices, avoiding control failures or misunderstandings caused by protocol incompatibility.

[0064] Step S212: Control the smart home device according to the current device status and / or target control command.

[0065] In this embodiment, the current device status or encoded target control commands obtained by the smart home gateway are used to directly control or adjust the behavior of the smart home devices.

[0066] This method involves a local intelligent decision-making and control mechanism for smart home systems. After the status data acquired from the devices is uploaded to the gateway, the internal rule engine judges and decides whether to issue control commands to the relevant devices based on preset automation rules (such as automatically activating the air conditioner's cooling mode if the temperature exceeds a set value). Simultaneously, for control commands input by the user through an application or other control interface, the gateway converts these commands into signals that the devices can recognize locally. Then, through the previously established multi-mode communication connection, the commands are sent to the corresponding smart home devices, guiding them to perform specific operations, such as turning lights on and off, adjusting curtain positions, and controlling the air conditioner temperature.

[0067] By implementing this control method, the intelligent responsiveness of smart homes and the convenience of the user experience are significantly improved. Firstly, localized intelligent decision-making allows automated scenarios to respond quickly to environmental changes or user behavior, eliminating the need to wait for long cloud processing times and drastically reducing response time, thus enhancing the system's immediacy and usability. Secondly, the local transmission and execution of control commands reduces the impact of network latency and external interference. Especially in situations of network instability or outages, users can still effectively control home devices, ensuring the system's continuous availability and stability.

[0068] As described above, in this embodiment, the integrated multi-mode communication chipset receives raw device communication data from smart home devices employing different wireless communication protocols. The multi-mode communication chipset is a hardware component in the smart home system that integrates multiple wireless communication functional modules. The smart home system includes smart home devices. The raw device communication data is parsed using a protocol identification algorithm to obtain device parsing data. A target protocol parsing plugin is selected from a cloud protocol library based on the device parsing data. After selecting the target protocol parsing plugin, it is stored in the local memory of the smart home system's gateway. The target protocol parsing plugin is used to process the raw device communication data to obtain the current device status of the smart home, and / or, the target protocol parsing plugin is used to encode control commands to obtain... It enables the gateway to recognize target control commands from smart home devices; it controls smart home devices based on the current device status and / or target control commands, achieving unified access and control of smart home devices across brands and protocols, eliminating barriers between different ecosystems. It employs a dual-mode control architecture combining local edge computing and cloud collaboration, reducing system dependence on the network and ensuring uninterrupted critical business functions even in network outages. It provides fine-grained, scenario-based device permission management, enhancing system security and preventing unauthorized operations and privacy leaks. This allows the gateway to have lifelong evolution capabilities, connect to devices from different brands, achieve high ecosystem coverage, and still execute automated scenarios locally even in network outages, reducing response time, enhancing reliability, and supporting more than 10 fine-grained permission settings, effectively preventing unauthorized operations and privacy leaks.

[0069] Therefore, the technical solution provided by the above embodiments of the present invention solves the technical problem of protocol compatibility and ecosystem barriers coexisting when various smart home devices in a smart home system are interconnected across brands in the related art.

[0070] According to the above embodiments of the present invention, receiving raw device communication data from smart home devices using different wireless communication protocols through an integrated multi-mode communication chipset includes: continuously monitoring the home network corresponding to the smart home system through the multi-mode communication chipset of the gateway to wait for receiving broadcast signals from smart home devices; and determining that the broadcast signal is raw device communication data after receiving the broadcast signal from the smart home device.

[0071] In this embodiment, firstly, in terms of the physical layout of the home network, to achieve comprehensive coverage and precise control of various protocol devices, a multi-protocol adaptive bridging box is deployed as the core hub in the central location of the home (such as the TV cabinet in the living room). This bridging box uses a quad-core ARM Cortex-A55 processor (1.8GHz), is equipped with 256MB DDR4 memory, and integrates multiple communication modules: including a TICC2652R7 chip supporting Zigbee 3.0 (receiver sensitivity -120dBm), a Nordicn RF5340 chip supporting Bluetooth 5.2 Mesh (throughput 2Mbps), and an Espressif ESP32-C6 module supporting Wi-Fi 6 (speed 150Mbps). Simultaneously, Bluetooth Mesh relay nodes and Zigbee routers are additionally deployed in densely populated areas (such as the kitchen and bedrooms) to form a multi-layered wireless mesh network, ensuring a signal strength > -85dBm (full signal strength through three walls) within a 200㎡ apartment, completely eliminating communication blind spots.

[0072] This method combines multimode communication technology with an active monitoring mechanism. The gateway's multimode communication chipset continuously monitors various frequency bands in the home network, actively searching for and receiving broadcast signals from various devices. These signals contain device status information, control requests, or protocol identifiers. Once a signal is detected, the gateway analyzes the signal content, including but not limited to vendor ID, device type, and protocol version, to determine whether the received data is valid original device communication data. If so, it proceeds to subsequent processing steps, such as protocol identification and data parsing.

[0073] By implementing this control method, broad compatibility and support for smart home devices are achieved, along with real-time monitoring of device status. First, multi-mode communication technology ensures the gateway can seamlessly connect to devices using various protocols, eliminating the need for manual configuration or additional adapter purchases by users, greatly simplifying the device access process and improving system flexibility. Second, the continuous monitoring mechanism enables the gateway to promptly capture the latest status changes or control requests from devices, responding quickly even when the network environment changes or new devices are added, avoiding information delays or loss, and enhancing the system's real-time performance and reliability.

[0074] According to the above embodiments of the present invention, selecting a target protocol parsing plugin from a cloud protocol library based on device parsing data includes: extracting the target device feature code of the smart home device from the device parsing data; matching the target device feature code with the cloud protocol library to obtain the target protocol parsing plugin, wherein the cloud protocol library stores multiple records of device feature codes and protocol parsing plugins.

[0075] In this embodiment, the feature extraction involves parsing fields such as vendor ID, message length, and checksum in the broadcast message (e.g., Zigbee devices contain a 16-bit manufacturer code, and Bluetooth devices contain a 128-bit UUID).

[0076] In a smart home system, each device has a unique identifier, containing key information such as the device's manufacturer, type, and supported communication protocols. The smart gateway extracts the target device's identifier from the received device parsing data and then uses this identifier to perform a high-precision match with a cloud-based protocol library. This cloud-based protocol library is a large database that stores records of various device identifiers and corresponding protocol parsing plugins, establishing a bridge between devices and protocols. When the gateway uploads the extracted identifier to the cloud, the cloud quickly locates the protocol parsing plugin compatible with the target device by calculating the similarity between identifiers or directly searching for matches, and then returns the plugin to the gateway.

[0077] By implementing this control method, the system's compatibility and scalability are greatly improved. First, the dynamic update and matching mechanism of the cloud-based protocol library ensures that the system can promptly support newly emerging smart devices on the market, without relying on hardware upgrades or manual configuration. Users only need to add new devices to the system, and the system can automatically identify and download the corresponding protocol parsing plugin, simplifying the device access process. Second, the selection and download of target protocol parsing plugins enables the gateway to correctly parse and process the device's communication data, converting it into a unified data format within the system, providing a technical foundation for device control, status monitoring, and the execution of automated scenarios.

[0078] According to the above embodiments of the present invention, matching the target device feature code with a cloud protocol library to obtain a target protocol parsing plugin includes: performing cosine similarity calculation on the target device feature code and each device feature code stored in the cloud protocol library to obtain a cosine similarity calculation result; determining the device feature code used when the calculation result is the highest among the cosine similarity calculation results as the target device feature code; and determining the protocol parsing plugin corresponding to the device feature code used when the calculation result is the highest as the target protocol parsing plugin.

[0079] In this embodiment, protocol matching involves calculating the cosine similarity (threshold > 0.92) between the feature code and the cloud protocol library (pre-stored 100+ protocol templates), and automatically loading the corresponding driver.

[0080] This method utilizes cosine similarity, a commonly used metric for measuring the similarity between two vectors in a multidimensional space, particularly suitable for comparing feature vectors. Specifically, the gateway treats the target device feature code extracted from the parsed device data as a multidimensional vector, where each dimension corresponds to a specific attribute of the device (such as manufacturer ID, protocol version number, message length, etc.). This vector is then compared one by one with all device feature code vectors stored in the cloud protocol library, calculating the cosine similarity between the two vectors to measure their similarity. The system automatically identifies the device feature codes with the highest cosine similarity calculation results—the records most similar to the target device—and marks the corresponding protocol parsing plugin as the target plugin for subsequent data parsing and instruction conversion.

[0081] By implementing this control method, the accuracy and efficiency of smart home systems in device identification and protocol parsing are significantly improved. First, it effectively filters the most matching target plugins from a massive database of device signatures, ensuring accurate matching every time, even in the face of a complex and ever-changing smart home device ecosystem. This reduces device control failures or system anomalies caused by protocol parsing errors. Second, the rapid identification and adaptation of new devices improves system response speed and ease of operation. Users no longer need to perform complex configurations or wait for lengthy device scans; the system can quickly download the required plugins and begin device control.

[0082] According to the above embodiments of the present invention, the unified control method further includes: when a smart home device first accesses the smart home system, after the smart home device is powered on, performing two-way authentication on the smart home device to obtain a two-way authentication result, wherein the two-way authentication includes: confirmation operation of the physical button of the smart home device and digital certificate signing; when both two-way authentication results are passed, the smart home device is allowed to join the smart home system.

[0083] In this embodiment, security authentication introduces a two-way verification process of "physical button confirmation + digital certificate signature", combined with a dedicated security chip (ATECC608B) to prevent unauthorized access.

[0084] When a new device is powered on, it must undergo a rigorous verification process before being recognized by the system. First, the user needs to confirm the device via a physical button – a human-interventional verification step that proves the device is physically in the intended environment and has been activated by the actual user. Second, the device uses a pre-installed security chip (such as ATECC608B) to generate a digital certificate and signs it using the ECDSA algorithm to verify the device's identity and legitimacy, preventing counterfeit or unauthorized devices from accessing the system. Upon receiving the device's request and signature information, the cloud performs a second verification to confirm the device's legitimacy and the authenticity of the user's actions. Only when both verifications pass will the smart home gateway allow the device to join the system and assign it the appropriate network address and control permissions.

[0085] Implementing this control method enhances the security and reliability of the smart home system. First, the dual verification of physical button confirmation and digital certificate signing ensures that each device undergoes rigorous identity verification before connection, effectively resisting intrusion by unauthorized devices or remote hacker attacks, and protecting the home network from unauthorized access. Second, through this mechanism, the smart home system can establish a chain of trust, ensuring that every interaction between devices and users occurs within a secure framework, significantly reducing the risk of privacy leaks and data tampering.

[0086] According to the above embodiments of the present invention, the unified control method further includes: when the smart home system is detected to be in a network outage state, triggering the start of the local rule engine of the smart home system, wherein the local rule engine is a software component running on the smart home device or the gateway of the smart home system, the software component is used to process and execute predefined scenario-based rules, the scenario-based rules are predefined operating parameters and operating modes of the smart home device in different scenarios; after determining that the local rule engine has started, controlling the smart home device to execute the scenario-based control instructions corresponding to the preset automation scenario.

[0087] In this embodiment, for localized intelligent decision-making, a Lua virtual machine rule engine is used in the bridging box. User-preset automation scenarios (such as "door and window sensors open → automatic light turn on") are executed locally in the local area network with low response latency (<0.5 seconds). The core rules are still 100% available when the network is disconnected. Basic linkage is maintained through Bluetooth Mesh to support complex condition judgments (such as "when the temperature is >28°C and the light intensity is <10 lux for 5 minutes, the air conditioner is started to cool down").

[0088] When the smart home system detects a network outage, it immediately triggers the local rule engine pre-deployed on the gateway. The local rule engine is a software component whose core function is to process and execute a series of predefined, scenario-based rules. These rules are customized by users based on their daily needs and habits, covering specific scenarios such as "automatically turning off non-essential appliances at night" and "automatically arming the security system in 'away mode'." In an offline environment, the gateway no longer relies on cloud-based commands or data synchronization, but instead autonomously judges and executes control actions based on its built-in rule engine. The local rule engine compares the current device status and information collected by environmental sensors, such as brightness, temperature, and humidity, with preset automation scenario conditions. Once the conditions are met, it immediately generates and sends corresponding scenario-based control commands to the relevant devices, thus achieving automated control unaffected by network fluctuations.

[0089] By implementing this control method, the stability and user experience of the smart home system have been significantly improved. First, the local rule engine ensures that the smart home system can maintain core functions, such as emergency notifications and security alarms, even when the network is down, greatly enhancing the system's reliability in emergencies and avoiding security risks caused by network interruptions. Second, the local execution of automated scenarios significantly shortens control response time. Users no longer need to wait for the network to be restored before manually intervening; smart devices can respond instantly to environmental changes, such as automatically turning on the air conditioner when the indoor temperature is detected to be too high, improving convenience and comfort.

[0090] According to the above embodiments of the present invention, the unified control method further includes: when the network of the smart home system is detected to be restored, automatically synchronizing the device data and control records generated by the offline devices corresponding to the offline state of the smart home system to the cloud.

[0091] In this embodiment, the system employs a two-tiered access control model for secure command execution. For device-level security, each operation command is encrypted using AES-128-GCM, with the key dynamically rotated every 24 hours. For user-level permissions, a three-tiered role system based on the RBAC model is used: owner (full access), family member (control of designated devices), and visitor (temporary basic operations), preventing unauthorized access. This extends enterprise-level security management to the home environment. This systematic integration addresses the pain points of existing technologies, such as high response latency and unavailability during network outages.

[0092] This method is based on a data caching and network recovery monitoring mechanism. When the system detects a network interruption, it temporarily stores critical data such as device status changes and user control commands in the gateway's local cache instead of immediately uploading them to the cloud. This caching mechanism ensures that the system can continue to collect and process data even in a network outage environment, avoiding data loss or delayed execution of control commands. Subsequently, once the network service is re-established, the system immediately triggers the network recovery monitoring mechanism to automatically detect the network status and confirm that the communication link has been restored. At this time, the gateway begins to upload the device data and control log data accumulated in the local cache to the cloud through an encrypted channel. Data synchronization algorithms are used to ensure the consistency between the cloud database and the local cache data. Considering network bandwidth and data transmission efficiency, strategies such as batch uploading and differential backup may be adopted.

[0093] By implementing this control method, the impact of network fluctuations on the data integrity and continuity of smart home systems is effectively addressed. First, the caching and synchronization of device data and control records ensures that user operation records and device status changes are not lost during network outages, providing users with a seamless experience. Even network interruptions do not affect the tracing of historical data and device management. Second, this mechanism enhances system reliability. Even in environments with unstable networks or service interruptions, users can still execute automated scenarios and control commands through the local rule engine without worrying about the loss of operation records.

[0094] Figure 3 This is a flowchart of an optional unified control method for smart home devices according to an embodiment of the present invention, such as... Figure 3 As shown, physical signal access is achieved through modules such as Zigbee 3.0, Bluetooth 5.2 Mesh, and Wi-Fi 6 at the hardware interface layer. After being connected by a unified driver framework, the core processing layer performs protocol identification and decoding, unified data model conversion, and security authentication. Then, the rule engine executes automated scenarios, data mapping and forwarding, and device monitoring and self-healing. Data is transmitted to the application and service layer through the data exchange bus to provide unified control APIs, permission management, and network configuration services. Finally, it faces users through unified control entry points such as WeChat mini-programs, web management backends, and voice assistants, forming a full-link smart device management architecture from device access to user interaction. This architecture provides an innovative and comprehensive solution that effectively addresses the core challenges in the smart home field, achieving broad device compatibility, high system security, local execution of automated scenarios, and convenient user control. This marks a step forward for smart home technology towards greater intelligence, personalization, and security.

[0095] As described above, the technical solution provided by the embodiments of this invention constructs a smart gateway hardware unit that supports multi-protocol adaptive conversion. Through a unified intermediate data format, it shields the differences in proprietary protocols between different brands, achieving seamless access and control across ecosystem devices. A dual-mode control architecture combining local edge computing and cloud collaboration is designed, pushing core control logic and automation rules to the gateway for local execution, ensuring uninterrupted critical business operations during network outages. An enterprise-level RBAC (Role-Based Access Control) model is introduced into smart home scenarios, providing granular, secure, and controllable device permission management capabilities for complex user relationships such as families, rental properties, and homestays. Dynamic expansion capabilities, through a cloud protocol library and hot-swappable mechanism, enable the gateway to evolve throughout its lifecycle. Reliability is improved; even in network outages, automated scenarios can be executed locally, reducing local scenario triggering and execution response time—at least twice as fast as cloud-based solutions. It supports more than 10 fine-grained permission settings for individual devices, meeting family role management needs, successfully preventing unauthorized operation attempts, and reducing the risk of user privacy data leakage.
