[0026] Embodiment 1:

[0027] As Figure 1As shown in the figure, the present invention provides a data synchronization method for Internet of Things nodes, including the following steps: S1. When the Internet of Things is networked, the comprehensive performance of the Internet of Things nodes is monitored in real time, and the basic synchronization node, the core synchronization node, and the edge synchronization node are dynamically elected according to the comprehensive performance of the Internet of Things nodes; S2. The network data during the Internet of Things networking process is stratified to obtain a basic data layer, a control command layer, and a user interaction layer; S3. The basic synchronization node, the core synchronization node, and the edge synchronization node are used to respectively execute the data synchronization tasks of the basic data layer, the control command layer, and the user interaction layer.

[0028] The data synchronization method for Internet of Things networking provided in this embodiment elects appropriate synchronization nodes according to the comprehensive performance of Internet of Things nodes to meet the synchronization requirements of different data, can dynamically and flexibly select the most suitable synchronization node for the current network state, avoids the problem that fixed synchronization nodes are likely to cause network congestion, and significantly improves the data synchronization efficiency of the network; and stratifies the data in the network, and uses nodes with different performances to perform data synchronization tasks at different levels, effectively dispersing the network load, avoiding the situation of single-node overload, improving the response speed and synchronization efficiency of the overall network, and making the data synchronization efficient and with low latency.

[0029] Next, in combination with Figure 1 and Figure 2 , the specific implementation steps of the data synchronization method for Internet of Things networking provided in this embodiment will be introduced in detail:

[0030] First, execute step S1. When the Internet of Things is networked, the comprehensive performance of the Internet of Things nodes is monitored in real time, and the basic synchronization node, the core synchronization node, and the edge synchronization node are dynamically elected according to the comprehensive performance of the Internet of Things nodes. A synchronization node refers to a device or system used to implement the data synchronization function in the network. For example, in a distributed network system, multiple nodes store and process data, and the synchronization node is responsible for coordinating the data between the nodes to ensure that the data remains consistent on different nodes. In traditional Internet of Things networking, the selection of synchronization nodes usually depends on fixed presets or is uniformly managed by the central node. However, this method is likely to cause performance bottlenecks of synchronization nodes and network congestion in the face of scenarios with a large number of devices and dynamic network changes. This embodiment solves this problem through dynamic election; comprehensively considers the performance of each node, and dynamically optimally selects appropriate synchronization nodes to process different types of data transmission.

[0031] Furthermore, as shown in Figure 2As shown, step S1 includes: S11. Obtain the performance parameters of IoT nodes in real time monitoring; among them, the performance parameters include the communication ability, historical response time, location in the IoT, current load condition, and energy consumption condition of the IoT nodes; first, the communication abilities of all nodes will be evaluated, including bandwidth, processing speed, storage capacity, etc., and these parameters will be important parameters for calculating the comprehensive performance; then, record the historical response time of the nodes, and these data are used to evaluate the stability and reliability of the nodes; then, according to the geographical location and current load condition of the nodes in the network, preferentially select the devices at the network center location or the nodes with lower load to have stronger performance; finally, the energy consumption condition of the nodes also needs to be considered, and preferentially select the nodes with sufficient energy to have stronger performance, so as to extend the running time of the nodes and the overall life of the network. S12. According to the performance parameters, calculate the comprehensive performance of the IoT nodes by weighted calculation; calculate the comprehensive performance of the nodes by weighted calculation according to the above parameters, comprehensively consider the performance of each aspect of the nodes, and ensure the efficiency of data synchronization. S13. Dynamically elect the basic synchronization nodes, core synchronization nodes, and edge synchronization nodes among the IoT nodes according to the comprehensive performance.

[0032] Specifically, according to the comprehensive performance, select the currently relatively idle nodes as the basic synchronization nodes, which are mainly responsible for the synchronization of basic data and provide a basic guarantee for the stable operation of the entire network. According to the comprehensive performance, elect the IoT nodes with the comprehensive performance greater than the high processing threshold as the core synchronization nodes. For example, the high processing threshold can be set to 80%, and the IoT nodes with the weighted value of the comprehensive performance greater than 80% can be elected as the core synchronization nodes. The IoT nodes with the comprehensive performance greater than the high processing threshold usually have high processing capabilities and low latency, and can perform data synchronization accurately and quickly. Therefore, letting the core synchronization nodes be responsible for the synchronization of important data plays a crucial role in the overall performance and stability of the network. According to the comprehensive performance, elect the edge layer nodes as the edge synchronization nodes; among them, the edge layer nodes are the IoT nodes deployed on the periphery of the IoT network. The edge synchronization nodes are located at the edge of the network, close to the data source or terminal devices, and they can perform data processing and synchronization locally, reduce data transmission latency, and improve the response speed and efficiency of the system. By dynamically electing appropriate synchronization nodes, the performance of the IoT network can be optimized, the accuracy and timeliness of data transmission can be improved, and the reliability and stability of the entire system can be enhanced.

[0033] Then, execute step S2. Stratify the network data during the IoT network formation process to obtain the basic data layer, control command layer, and user interaction layer. Traditional IoT network formations usually adopt a unified data synchronization strategy, which is prone to resource waste and low synchronization efficiency in scenarios with a large variety of data types and different synchronization requirements. In this embodiment, through the hierarchical data synchronization strategy, the data in the network is divided into multiple levels to ensure that key data can be preferentially processed.

[0034] Specifically, the basic data layer includes basic information such as environmental data and node status, such as physical quantity data like temperature, humidity, pressure, light intensity, and motion state. The update frequency of these data is relatively low, and the real-time requirement is not high. Therefore, basic synchronization nodes can be used to synchronize them to avoid network congestion caused by frequent data transmission.

[0035] The control command layer includes control instructions for nodes and lightsaber operation data. For example, when the user issues an instruction to turn off the smart light through the mobile application, the control command layer will parse and convert this instruction and then accurately send it to the corresponding smart light fixture to execute the turn-off operation. This instruction is the data of the control command layer. These data are crucial for the stable operation of the network and must ensure fast and accurate synchronization. Therefore, core synchronization nodes can be used to synchronize them to ensure the smooth operation of the network.

[0036] The user interaction layer includes information such as user input and feedback, such as data like the user entering text, clicking buttons, etc. on the APP, as well as operation success prompts and error warnings. These data usually change frequently, but have a relatively high tolerance for synchronization latency. Therefore, edge synchronization nodes are selected for synchronization to reduce the load pressure on the core network. This hierarchical synchronization strategy effectively distributes the network load, avoids the situation of single-point overload, and at the same time ensures that key data can be preferentially processed, improving the overall network response speed and synchronization efficiency.

[0037] Finally, execute step S3: Use basic synchronization nodes, core synchronization nodes, and edge synchronization nodes to respectively execute the data synchronization tasks of the basic data layer, control command layer, and user interaction layer. By corresponding different types of synchronization nodes to different data layers and respectively executing their respective data synchronization tasks, a data synchronization system with clear levels and distinct divisions of labor is formed, which helps to improve the efficiency and accuracy of data synchronization and ensure data consistency and coordination among various parts of the system.

[0038] Specifically, step S3 includes: Regularly synchronize the data of the basic data layer through basic synchronization nodes; the data of the basic data layer includes environmental data and device status information. Since the data of the basic data layer does not change frequently and does not need to be updated frequently in a short period of time, basic synchronization nodes are used to synchronize it regularly. Real-time synchronize the data of the control command layer through core synchronization nodes; the data of the control command layer includes control instructions for IoT nodes and key operation data. Since the data of the control command layer needs to be updated frequently, core synchronization nodes with high processing capabilities and low latency are selected to synchronize it in real time. Synchronize the data of the user interaction layer through edge layer nodes. Since the data of the user interaction layer has a relatively high tolerance for synchronization latency, edge layer nodes can be used for data synchronization.

[0039] Furthermore, when data synchronization conflicts occur during the data synchronization tasks of the basic synchronization nodes, core synchronization nodes, and edge synchronization nodes, a conflict resolution mechanism based on timestamps is used to avoid data synchronization conflicts. Specifically, it includes: marking each data packet with a timestamp indicating the generation time; determining the new and old states of the data packets based on the timestamps, and selecting the latest data packets for data synchronization. During the synchronization process of IoT nodes, multiple devices may update the same data simultaneously, resulting in data conflicts. Most traditional conflict resolution methods rely on a central node for unified management, which is prone to delays and network bottlenecks. In this embodiment, a conflict resolution mechanism based on timestamps is used to avoid data synchronization conflicts. Even if delays or out-of-order situations occur during data transmission, the method in this embodiment can still ensure that the final state of the data correctly reflects the latest updates, avoiding data inconsistency issues, thus ensuring the consistency and accuracy during the data synchronization process. Even in a complex network environment, the integrity of the data can be effectively guaranteed.

[0040] Furthermore, after step S3, the method further includes: real-time monitoring of the network status of the IoT networking network, replacing the transmission path when network congestion occurs, or automatically reconfiguring the network when an IoT node failure is detected; by readjusting the connection relationships between each node, bypassing the faulty node, enabling other normal nodes to continue to communicate and cooperate with each other, thereby ensuring the stability and reliability of the entire IoT system and reducing the impact on the entire network caused by individual node failures. Real-time monitoring of the data transmission paths in the IoT networking network, and dynamically adjusting the data transmission paths in the IoT networking network according to the load conditions and transmission efficiency of the transmission paths to ensure optimal data transmission performance. This self-organizing optimization strategy improves the flexibility and stability of the network, and is particularly suitable for dynamic network environments where devices frequently join or leave.

[0041] Furthermore, after step S3, the method further includes: real-time monitoring of various performance indicators of the IoT networking network, such as bandwidth utilization rate, latency, packet loss rate, etc., and automatically adjusting the selection of synchronization nodes, the frequency of data synchronization, and the data transmission paths according to the monitoring data; where the synchronization nodes include basic synchronization nodes, core synchronization nodes, and edge synchronization nodes. To further improve the stability of the network and the efficiency of data synchronization, the method in this embodiment real-time monitors the performance status and communication quality of each node in the network, and automatically adjusts the parameters according to the monitoring results. According to the monitoring data, automatically adjust the selection of synchronization nodes, the synchronization frequency, and the data transmission paths to adapt to changes in network conditions, ensuring that the network is always in the best operating state. It is also possible to continuously optimize the measurement and control by analyzing historical monitoring data to improve the network's self-adaptive ability. This performance monitoring and self-adjustment mechanism ensures the efficient operation of the network, can handle complex and changing network environments, and improves the reliability and availability of the system.
