[0001] This invention relates to the field of communication technology, and more specifically to networking methods, devices, electronic equipment, and storage media for smart home devices. Background Technology

[0002] With the rapid development of IoT technology, smart home devices have become increasingly widespread, with a large number of various brands and models flooding the market. However, these smart home devices typically come from different manufacturers and use different communication protocols and control platforms, forcing users to operate multiple applications to manage various devices separately, which is cumbersome and makes it difficult to achieve inter-device collaboration. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide a networking method, apparatus, electronic device, and storage medium for smart home devices.

[0004] In a first aspect, embodiments of the present invention provide a method for networking smart home devices, including: Obtain the communication distance and connection relationship between multiple home devices to be networked and each subnet controller within the target area. The connection relationship includes at least one home device to be networked that is connected to a subnet controller. Based on communication distance and connection relationship, determine the bus connection method between each home device to be networked and the corresponding subnet controller; A communication connection is established between the home devices to be networked and the corresponding subnet controllers based on a bus connection method, resulting in multiple subnets; For any subnet, obtain the attribute information of the subnet controllers within the subnet, as well as the association relationships between the subnet controllers and other subnet controllers; Establish network connections between multiple subnets based on attribute information and relationships to control the networking of multiple home devices to be networked within the target area.

[0005] The smart home device networking method provided in this invention determines the bus connection method between each home device and its corresponding subnet controller based on the communication distance and connection relationship between the home devices to be networked and the subnet controller. Then, it constructs the network architecture of the entire target area according to the relationships between subnets. This not only improves networking efficiency but also ensures network stability and scalability. Simultaneously, by calculating the communication distance and optimizing the connection relationship, it effectively reduces signal interference and transmission delay, improving the overall performance and user experience of smart home devices. Furthermore, the unified networking method enables interconnection and interoperability between smart home devices of different brands and models, greatly simplifying the operation process and enhancing the collaborative capabilities between devices, thereby providing users with a more convenient and intelligent living experience.

[0007] In conjunction with the first aspect, in one implementation, based on communication distance and connection relationships, the bus connection method between each home appliance to be networked and its corresponding subnet controller is determined, including: The subnet controller corresponding to each home appliance to be networked is determined based on the connection relationship; The communication distance is compared with the first communication threshold to obtain the first comparison result; If the first comparison result indicates that the communication distance is less than or equal to the first communication threshold, then the bus connection method between the home device to be networked and the corresponding subnet controller is determined to be a single-line bus connection.

[0008] In conjunction with the first aspect, in one implementation, determining the bus connection method between each home appliance to be networked and its corresponding subnet controller based on communication distance further includes: If the first comparison result indicates that the communication distance is greater than the first communication threshold, then the communication distance is compared with the second communication threshold to obtain the second comparison result, where the second communication threshold is greater than the first communication threshold. If the second comparison result indicates that the communication distance is less than or equal to the second communication threshold, then the bus connection method between the home device to be networked and the corresponding subnet controller is determined to be a two-wire bus connection.

[0009] In conjunction with the first aspect, in one implementation, network connections between multiple subnets are established based on attribute information and association relationships to control the networking of multiple home devices to be networked within a target area, including: Determine whether the subnet controller has a network port based on attribute information; If the subnet controller does not have a network port, then it is determined whether the subnet where the subnet controller is located is interconnected with the subnets where other subnet controllers are located through a protocol adapter based on the association relationship; If the subnet where the subnet controller is located is interconnected with the subnets where other subnet controllers are located through a protocol adapter, then a communication connection between the subnets and other subnets is established based on the protocol adapter, and a network connection between other subnet controllers and the network controller is established based on the network port, so as to control the networking of multiple home devices to be networked in the target area.

[0010] In conjunction with the first aspect, in one implementation, establishing network connections between multiple subnets based on attribute information and association relationships to control the networking of multiple home devices to be networked within a target area further includes: If both the subnet controller and other subnet controllers have network ports, then a network connection between the subnet and the network controller is established based on the network port of the subnet controller, and a network connection between other subnets and the network controller is established based on the network ports of other subnet controllers, so as to control the networking of multiple home devices to be networked in the target area.

[0011] In conjunction with the first aspect, in one embodiment, the above method further includes: Obtain the communication distance between newly added home devices to be networked and each subnet controller, as well as the current device capacity of each subnet controller; If the current device capacity of each subnet controller is less than the capacity threshold, then a subnet controller corresponding to the newly added home device to be networked is established based on the communication distance, and a connection is established. If the current device capacity of each subnet controller is greater than the capacity threshold, the location of the new subnet controller is determined based on the device location of the new home device to be networked, and a connection is established.

[0012] Secondly, embodiments of the present invention provide a networking device for smart home devices, comprising: The data acquisition module is used to acquire the communication distance and connection relationship between multiple home devices to be networked and each subnet controller within the target area.

[0013] The smart home device networking apparatus provided in this invention determines the bus connection method between each home device and its corresponding subnet controller based on the communication distance and connection relationship between the home device to be networked and the subnet controller. Then, it constructs the network architecture of the entire target area according to the association relationship between subnets. This not only improves networking efficiency but also ensures network stability and scalability. Simultaneously, by calculating the communication distance and optimizing the connection relationship, it effectively reduces signal interference and transmission delay, improving the overall performance and user experience of smart home devices.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] According to an embodiment of the present invention, a method for networking 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.

[0021] This invention provides a method for networking smart home devices. Figure 1 This is a flowchart of a smart home device networking method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps: Step S101: Obtain the communication distance and connection relationship between multiple home devices to be networked and each subnet controller within the target area.

[0022] The connection relationship includes at least one home appliance device to be networked that is connected to the subnet controller.

[0023] In one possible implementation, when obtaining the connection relationship between multiple home devices to be networked and each subnet controller within the target area, the current device capacity of each subnet controller can be obtained first; then, based on the communication distance and device capacity, the connection priority between each home device to be networked and each subnet controller can be determined; finally, the connection relationship between the home devices to be networked and the subnet controller can be determined according to the connection priority and communication distance.

[0024] Specifically, the connection priority of a subnet controller to other smart home devices can be reduced first, based on the subnet controller's capacity threshold. When the device capacity of a subnet controller approaches or reaches the threshold, its connection priority to other smart home devices can be lowered to avoid overloading the subnet controller. Next, a weighted algorithm can be used to determine connection priorities by combining communication distance and device capacity, ensuring the rationality and efficiency of connection relationships. Furthermore, the type and functional requirements of the smart home devices to be networked can also be considered when determining connection relationships to ensure the stability and reliability of the entire smart home system.

[0025] As an example, assume there are three subnet controllers (Controller A, Controller B, and Controller C) and five home appliances to be networked (Device 1 to Device 5) within the target area. First, determine the device capacity of each subnet controller: Controller A currently supports 8 devices (capacity threshold is 10), Controller B supports 5 devices (threshold is 10), and Controller C supports 12 devices (overloaded, threshold is 10). Simultaneously, measure the communication distance between each device and the controller: Device 1 is 5 meters from Controller A, 10 meters from Controller B, and 15 meters from Controller C; Device 2 is 8 meters from Controller A, 5 meters from Controller B, and 12 meters from Controller C; and so on.

[0026] Next, a weighted algorithm is used to determine connection priorities, with communication distance weighted at 0.6 (shorter distance, higher priority) and device capacity weighted at 0.4 (lower capacity, higher priority). Taking device 1 as an example, its priority score with controller A is calculated as follows: distance score is (1 / 5)*0.6=0.12, capacity score is (1-8 / 10)*0.4=0.08, total score is 0.20; with controller B: distance is (1 / 10)*0.6=0.06, capacity is (1-5 / 10)*0.4=0.20, total score is 0.26; with controller C: distance is (1 / 15)*0.6=0.04, capacity is (1-12 / 10)*0.4=-0.08 (negative score due to overload), total score is -0.04. Therefore, the priority order of device 1 is controller B>controller A>controller C.

[0027] Furthermore, considering device type and functional requirements: Device 1, a high-definition camera (high bandwidth requirement), is preferentially assigned to controller B, which has a lower load; Device 2, a smart light bulb (low bandwidth), is assigned to controller A based on similar calculations. Finally, based on priority ranking and communication distance, the connection relationships are determined: Device 1 connects to controller B, Device 2 connects to controller A, Device 3 connects to controller B, Device 4 connects to controller A, and Device 5 connects to controller C (reassigned after adjusting load capacity). This example ensures efficient and reliable networking through quantitative calculations, avoiding overload and optimizing system stability.

[0028] Step S102: Based on the communication distance and connection relationship, determine the bus connection method between each home device to be networked and the corresponding subnet controller.

[0029] The bus connection methods include single-wire bus connection and dual-wire bus connection. Single-wire bus connection can reduce wiring workload by 60%, while dual-wire bus connection can enhance long-distance anti-interference. Furthermore, the communication methods of single-wire bus connection and dual-wire bus connection can avoid wireless interference problems and eliminate network fault points.

[0030] In one possible implementation, when determining the bus connection method between each home appliance to be networked and its corresponding subnet controller based on communication distance and connection relationship, the subnet controller corresponding to each home appliance to be networked can be determined based on the connection relationship; the communication distance is compared with a first communication threshold to obtain a first comparison result; if the first comparison result indicates that the communication distance is less than or equal to the first communication threshold, then the bus connection method between the home appliance to be networked and its corresponding subnet controller is determined to be a single-wire bus connection. If the first comparison result indicates that the communication distance is greater than the first communication threshold, then the communication distance is compared with a second communication threshold to obtain a second comparison result, where the second communication threshold is greater than the first communication threshold; if the second comparison result indicates that the communication distance is less than or equal to the second communication threshold, then the bus connection method between the home appliance to be networked and its corresponding subnet controller is determined to be a two-wire bus connection.

[0031] Specifically, the first communication threshold can be set as the maximum allowable value for short-distance communication, such as 5 meters, while the second communication threshold can be set as the upper limit for medium-distance communication, such as 15 meters, to adapt to the layout needs of different home environments. The dual-wire bus connection enhances communication reliability through redundant signal paths, making it suitable for medium- to long-distance transmission or environments with potential electromagnetic interference, ensuring the integrity of data transmission. Furthermore, the specific value ranges of the first and second communication thresholds can be adjusted according to the user's actual needs.

[0032] Furthermore, if the second comparison result indicates that the communication distance is greater than the second communication threshold, the communication distance is compared with the third communication threshold to obtain the third comparison result, where the third communication threshold is greater than the second communication threshold. If the third comparison result indicates that the communication distance is less than or equal to the third communication threshold, the bus connection method between the home device to be networked and the corresponding subnet controller is determined to be a multi-line bus connection to enhance signal stability and data transmission rate. In addition, when the communication distance exceeds the third communication threshold, it indicates that the distance between the home device to be networked and the subnet controller is too far or there is a significant risk of interference. In this case, the connection path needs to be re-evaluated or an alarm should be triggered to avoid communication failures due to signal attenuation or interference, further optimizing the communication quality and stability after networking. Furthermore, networking strategies can be dynamically adjusted based on connection relationships, such as introducing repeater devices or switching to a backup wireless connection mode, to ensure network reliability and compatibility.

[0033] As an example, in a typical smart home scenario, suppose there is a subnet controller in the living room area. The devices to be networked include smart bulb A (3 meters away from the subnet controller), temperature sensor B (10 meters away from the subnet controller), and curtain controller C (20 meters away from the subnet controller). First, based on the connection relationship, smart bulb A corresponds to the living room subnet controller, and its communication distance of 3 meters is less than the first communication threshold (5 meters), so a single-wire bus connection is used; the communication distance of temperature sensor B is 10 meters, which is greater than the first threshold but less than the second threshold (15 meters), so a dual-wire bus connection is used to enhance signal redundancy; the communication distance of curtain controller C is 20 meters, which is greater than the second threshold but less than the third communication threshold (25 meters), so a multi-wire bus connection is used to improve data transmission rate and stability. If a device, such as security camera D, is more than 30 meters away from the controller, exceeding the third threshold, the system triggers an alarm and automatically suggests introducing a repeater device or switching to a backup wireless mode to ensure network reliability.

[0034] Step S103: Establish communication connections between the home devices to be networked and the corresponding subnet controllers based on the bus connection method to obtain multiple subnets.

[0035] As shown above, by establishing communication connections between the home devices to be networked and the corresponding subnet controllers based on a bus connection method, multiple subnets are obtained. This can effectively manage device communication within each subnet, ensure data transmission stability and low latency, while enabling hierarchical management, optimizing resource allocation, reducing the risk of single points of failure, and providing a scalable and highly reliable network architecture for smart home scenarios.

[0036] Specifically, within each subnet, the bus connection methods between the home appliances to be networked and the corresponding subnet controller include single-wire bus connection, dual-wire bus connection, and / or multi-wire bus connection. After establishing the physical connection between the home appliances to be networked and the corresponding subnet controller based on the bus connection methods of single-wire bus connection, dual-wire bus connection, and / or multi-wire bus connection, each subnet controller assigns a corresponding single-byte address (e.g., 0~256) to each home appliance to be networked based on the access order of the corresponding home appliances to be networked. Each home appliance to be networked is connected to the corresponding subnet controller in parallel, and each home appliance to be networked achieves coexistence through hardware address identification and conflict avoidance protocols; at the same time, single-byte address allocation and timing coordination can be automatically completed based on the subnet controller or protocol stack, thereby establishing communication connections and forming multiple subnets.

[0037] In one possible implementation, a communication connection is established between the home devices to be networked and the corresponding subnet controller based on a bus connection method. When multiple subnets are obtained, communication parameters can be configured for each subnet, including setting the data transmission rate, error detection mechanism, and timeout reconnection strategy, to adapt to the specific distance of the devices and the bus type. For example, a redundancy check algorithm can be enabled for a two-line bus, and a data fragmentation transmission protocol can be implemented for a multi-line bus, thereby optimizing network performance in real time and minimizing communication latency.

[0038] Specifically, the data transmission rate can be dynamically adjusted based on the actual distance between the home devices to be networked and the subnet controller. For example, for devices within 20 meters, a higher rate such as 1Mbps is used to improve efficiency, while for devices beyond 20 meters, the rate is reduced to 500Kbps to enhance signal stability. The error detection mechanism can combine cyclic redundancy check (CRC) or parity check algorithms to monitor data packet integrity in real time and automatically trigger a retransmission process when an error is detected, ensuring data accuracy. The timeout reconnection policy sets a default timeout of 5 seconds and configures a maximum of 3 retries. If consecutive failures occur, a fault diagnosis module is activated to analyze network bottlenecks such as signal interference or bus load issues, and parameters are dynamically adjusted to restore the connection.

[0039] Furthermore, for two-wire buses, in addition to redundancy checks, parallel transmission of identical data copies can enhance fault tolerance. For multi-wire buses, data fragmentation protocols can be subdivided into fixed-size packets, and a priority queuing mechanism can be enabled to place critical control commands in a high-priority queue, ensuring real-time response. Simultaneously, encryption parameters such as AES-128 algorithms are introduced to protect communication security, and parameter combinations are customized according to device type (e.g., security cameras or smart locks). For example, high-security devices enable dual verification, while low-latency devices reduce protocol overhead, thereby minimizing communication latency while improving overall network robustness and adaptability.

[0040] Step S104: For any subnet, obtain the attribute information of the subnet controller within the subnet, as well as the association relationship between the subnet controller and other subnet controllers.

[0041] The attribute information for each subnet controller includes device capacity threshold, processor type, memory capacity, supported communication protocol types, and device identifier. The relationships between subnet controllers include the physical connection method, communication protocol compatibility, and data transmission path.

[0042] Step S105: Establish network connections between multiple subnets based on attribute information and association relationships to control the networking of multiple home devices to be networked within the target area.

[0043] Multiple subnets can be connected to the network controller via Ethernet bridges through the network ports of their respective subnet controllers, thus achieving subnet-to-mainnet connectivity. Communication between the subnet and the mainnet is MAC layer communication (802.2), avoiding IP layer configuration, IP address conflicts, and router dependencies (i.e., no IP dependency: UDP / TCP is not used, avoiding router dependencies and complex IP configurations); the communication bandwidth is 10M / 100M, ensuring smooth operation of large-scale devices (such as cameras and voice terminals); a 2-byte network ID or a 6-byte extended address is used to support ultra-large-scale networking (tens of thousands of devices).

[0044] Specifically, at the subnet layer, data formats are automatically converted between subnets via protocol adapters to achieve transparent transmission. Between the subnet and the main network, each subnet is connected to the network controller via an Ethernet bridge. The Ethernet bridge is responsible for mapping the short address (1 byte) of the subnet to the long address (2 / 6 bytes) of the main network, encapsulating the data packet at the MAC layer, routing it at high speed through the Ethernet backbone, and finally decapsulating it and delivering it to the networked home devices by the bridge of the target subnet. No IP is involved in the entire process, which ensures the isolation between subnets and achieves low-latency interconnection within the main network.

[0045] In one possible implementation, when establishing network connections between multiple subnets based on attribute information and relationships to control the networking of multiple home appliances to be networked within a target area, the presence of a subnet controller can be determined based on attribute information. If the subnet controller does not have a network port, the relationship is used to determine whether the subnet containing the subnet controller is interconnected with other subnet controllers via a protocol adapter. If the subnet containing the subnet controller is interconnected with other subnet controllers via a protocol adapter, a communication connection is established between the subnets based on the protocol adapter, and a network connection is established between other subnet controllers and the network controller based on the network port, to control the networking of multiple home appliances to be networked within the target area. If both the subnet controller and other subnet controllers have network ports, a network connection is established between the subnet and the network controller based on the subnet controller's network port, and a network connection is established between other subnets and the network controller based on the network ports of other subnet controllers, to control the networking of multiple home appliances to be networked within the target area.

[0046] Specifically, when a subnet controller does not have a network port but the subnets are interconnected through a protocol adapter, the protocol adapter is responsible for converting the data format of subnets with different bus connection methods before communication, thereby realizing the communication connection between subnets and other subnets. This allows the home devices to be networked to be unaware of the physical layer differences between subnets. At the same time, other subnet controllers with network ports can be connected to the network controller to control the networking of multiple home devices to be networked in the target area.

[0047] As an example, consider a target area as the living room in a smart home environment, containing multiple home devices to be networked, such as a smart lighting subsystem, a security monitoring subsystem, and an environmental control subsystem. Specifically, the living room's attribute information indicates that the lighting subsystem controller does not have a network port, but the security monitoring subsystem controller does. Simultaneously, the relationship shows that the lighting and security monitoring subsystems are interconnected via a protocol adapter, which converts the single-wire bus data used by the lighting subsystem into a two-wire bus data format supported by the security monitoring subsystem. Based on this, when a subsystem controller (such as the lighting subsystem controller) does not have a network port, the system automatically detects its interconnection with the security monitoring subsystem via the protocol adapter, thus establishing a communication connection between the lighting and security monitoring subsystems using the protocol adapter. Simultaneously, a network connection is established between the security monitoring subsystem controller and the network controller through its network port, enabling unified network control of all home devices to be networked in the living room area. Furthermore, if the environmental control subsystem controller also has a network port, a direct connection is established with the network controller based on its network port, ensuring the entire networking process is efficient and reliable.

[0048] The smart home device networking method provided in this invention determines the bus connection method between each home device and its corresponding subnet controller based on the communication distance and connection relationship between the home devices to be networked and the subnet controller. Then, it constructs the network architecture of the entire target area according to the relationships between subnets. This not only improves networking efficiency but also ensures network stability and scalability. Simultaneously, by calculating the communication distance and optimizing the connection relationship, it effectively reduces signal interference and transmission delay, improving the overall performance and user experience of smart home devices. Furthermore, the unified networking method enables interconnection and interoperability between smart home devices of different brands and models, greatly simplifying the operation process and enhancing the collaborative capabilities between devices, thereby providing users with a more convenient and intelligent living experience.

[0049] This invention provides a method for networking smart home devices. Figure 2 This is a flowchart of a smart home device networking method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps: Step S201: Obtain the communication distance between the newly added home devices to be networked and each subnet controller, as well as the current device capacity of each subnet controller.

[0050] Step S202: If the current device capacity of each subnet controller is less than the capacity threshold, then establish the subnet controller corresponding to the newly added home device to be networked based on the communication distance, and establish a connection.

[0051] Step S203: If the current device capacity of each subnet controller is greater than the capacity threshold, then the location of the new subnet controller is determined based on the device location of the new home device to be networked, and a connection is established.

[0052] Specifically, when the capacity of all devices is less than the threshold, the subnet controller with the shortest communication distance is selected to establish a connection to minimize signal transmission delay and interference. The communication distance can be measured by received signal strength indication or calculated using a path loss model based on an indoor map. The capacity threshold is dynamically set based on the subnet controller's processing capacity, memory usage, and bandwidth utilization, for example, set to 80% of the controller's maximum number of connections to ensure network load balancing and stability. If all subnet controllers are overloaded, the installation location of the new subnet controller is determined using a weighted centroid algorithm based on the coordinates of the new device, combined with the topology and device distribution density of the target area. After the new controller is added, network reconfiguration is automatically performed, including reallocating connections to neighboring devices, updating the routing table, and optimizing signal coverage to avoid blind spots. For example, the location of the new controller must meet the principle of minimizing the average communication distance, while also considering the impact of physical obstacles such as walls.

[0053] Furthermore, if some subnet controllers have a capacity below the threshold while others have a capacity above it, the remaining capacity is assessed, and new devices are dynamically allocated to controllers with lower capacity. If capacity is insufficient, temporary load migration or the addition of new controllers is triggered. After all connections are established, signal quality is monitored in real time. If latency exceeds the threshold, connection relationships or controller layout are automatically adjusted to ensure network scalability and high reliability.

[0054] As an example, in a typical three-bedroom smart home scenario, there are three subnet controllers: Controller A is located in the living room (coordinates x=10, y=5), Controller B is located in the master bedroom (coordinates x=15, y=20), and Controller C is located in the second bedroom (coordinates x=25, y=10). A new device to be networked is a smart thermostat installed in the study (coordinates x=20, y=15). First, the communication distance between the device and each controller is measured using signal strength indicators: distance A is 8 meters, distance B is 6 meters, and distance C is 12 meters. Simultaneously, the device capacity of each controller is monitored: A is supporting 18 devices (capacity threshold set to 80% of the maximum connection count of 25, i.e., 20), B is supporting 22 devices (exceeding the threshold), and C is supporting 15 devices (below the threshold). Due to some controllers being overloaded (B's capacity 22 > 20) and others not being overloaded (A and C's capacity are both below 20), the remaining capacity is assessed: A has 2 remaining connection slots, and C has 5 remaining connection slots. Based on the principle of minimizing communication latency, the controller C (12 meters away) with the shortest distance and lowest load capacity is selected first. New devices are dynamically assigned to C and connections are established. After the connection is established, the real-time monitoring signal latency is 60ms, which is below the threshold of 100ms, and the network load is balanced and stable. If subsequent monitoring detects that the latency rises to 110ms, controller layout optimization is automatically triggered, such as migrating nearby devices to controller A, to ensure scalability and high reliability.

[0055] The smart home device networking method provided in this invention can intelligently allocate new device connections by dynamically assessing communication distance and device capacity, effectively minimizing signal transmission delay and interference, and improving network load balancing. Through load migration or the deployment of new controllers, it ensures low latency and high reliability in high-density device environments. Simultaneously, based on real-time monitoring of signal quality, it automatically optimizes connection relationships or controller layout to avoid coverage blind spots, enhancing network scalability and stability. Furthermore, by using a weighted centering algorithm to accurately locate new controllers and combining this with the indoor topology, it achieves efficient resource utilization, significantly improving the overall performance and user experience of the smart home system.

[0056] This embodiment provides a networking device for smart home devices, such as... Figure 3 As shown, it includes: The data acquisition module 301 is used to acquire the communication distance and connection relationship between multiple home devices to be networked and each subnet controller within the target area. The connection relationship includes at least one home device to be networked that is connected to the subnet controller. The bus connection module 302 is used to determine the bus connection method between each home device to be networked and the corresponding subnet controller based on the communication distance and connection relationship; The communication connection module 303 is used to establish a communication connection between the home devices to be networked and the corresponding subnet controllers based on a bus connection method, thereby obtaining multiple subnets; The relationship acquisition module 304 is used to acquire the attribute information of the subnet controllers within any subnet, as well as the association relationship between the subnet controllers and other subnet controllers; The networking control module 305 is used to establish network connections between multiple subnets based on attribute information and association relationships, so as to control the networking of multiple home devices to be networked within the target area.
