其中，子节点的业务处理能力能够表征该子节点可以处理的业务数据量的最大峰值，而将子节点的实时业务处理量和该子节点的业务处理能力进行比较，可确定该子节点在当前时刻所处理的业务数据量是否超出其处理能力，进而在确定子节点的实时业务处理量超过该子节点的业务处理能力的情况下，确定该子节点发生网络拥塞故障。Among them, the business processing capability of a child node can represent the maximum peak amount of business data that the child node can process. By comparing the real-time business processing volume of the child node with the business processing capability of the child node, it can be determined that the child node is currently Whether the amount of business data processed at any time exceeds its processing capacity, and then when it is determined that the real-time business processing volume of the sub-node exceeds the business processing capacity of the sub-node, it is determined that the sub-node has a network congestion failure.
当该子节点发生网络拥塞故障时，需要对该子节点的业务数据量进行分流，以减少该子节点的业务处理压力。例如，通过主节点与子节点之间的支持端到端通信的网络连接模式，将该子节点的部分业务分流至主节点，以使主节点可以缓解该子节点的业务处理压力。When a network congestion failure occurs on the sub-node, the business data volume of the sub-node needs to be offloaded to reduce the business processing pressure of the sub-node. For example, through a network connection mode that supports end-to-end communication between the main node and the sub-node, part of the business of the sub-node is offloaded to the main node, so that the main node can relieve the business processing pressure of the sub-node.
在一些具体实现中，向子节点发送第一切换消息，以供子节点将其网络连接模式切换为支持端到端通信的网络连接模式之后，还包括：在依据网络状态信息确定子节点恢复正常的情况下，生成第二切换消息；依据第二通信连接，向子节点发送第二切换消息，以供子节点将其网络连接模式切换为网状网络的连接模式。In some specific implementations, after sending the first switching message to the child node for the child node to switch its network connection mode to a network connection mode that supports end-to-end communication, it also includes: determining that the child node returns to normal based on the network status information. of In this case, a second switching message is generated; according to the second communication connection, the second switching message is sent to the child node, so that the child node switches its network connection mode to the connection mode of the mesh network.
其中，第二切换消息用于指示子节点恢复其初始的网络连接模式(如，网状网络的连接模式等)。The second switching message is used to instruct the child node to restore its initial network connection mode (such as the connection mode of a mesh network, etc.).
当主节点获得的网络状态信息能够表征子节点与主节点之间的基于第一通信连接(如，网状网络的连接模式等)的通信恢复正常时，表征该子节点可以继续通过第一通信连接与主节点进行通信，从而可以断开子节点与主节点之间的基于第二通信连接(如，端到端的通信连接)的连接方式，使主节点可以与子节点之间能够通过网状网络的连接模式进行通信，以减少主节点的处理压力。此时，主节点无需再与子节点之间保持端到端的通信连接，能够使主节点可以释放通信资源，用以处理其他故障子节点的通信信息，提升通信网络的系统稳定性。When the network status information obtained by the master node can indicate that the communication between the child node and the master node based on the first communication connection (such as the connection mode of the mesh network, etc.) returns to normal, it indicates that the child node can continue to communicate through the first communication connection. Communicate with the master node, so that the connection between the child node and the master node based on the second communication connection (such as an end-to-end communication connection) can be disconnected, so that the master node can communicate with the child nodes through the mesh network Communicate in connection mode to reduce the processing pressure on the master node. At this time, the master node no longer needs to maintain an end-to-end communication connection with the child nodes, which allows the master node to release communication resources to process the communication information of other failed child nodes and improve the system stability of the communication network.
在一些具体实现中，在依据网络状态信息确定子节点恢复正常之前，还包括：依据第二通信连接，采用子节点的预设配置信息对子节点使用的通信资源进行配置，以使子节点获取其需求的通信资源。In some specific implementations, before determining that the child node returns to normal based on the network status information, the method further includes: using the preset configuration information of the child node to configure the communication resources used by the child node according to the second communication connection, so that the child node obtains the communication resources it requires.
例如，预设配置信息可以包括：预设业务配置信息、预设网络参数配置信息和预设通信制式的配置信息中的至少一种。For example, the preset configuration information may include: at least one of preset service configuration information, preset network parameter configuration information, and preset communication format configuration information.
采用第二通信连接，将子节点所需的多个不同维度的预设配置信息发送给该节点，能够使该子节点快速准确的获取其需要的通信资源，加快子节点的通信效率，降低子节点发生故障的可能性，提升用户的使用体验。Using the second communication connection to send the preset configuration information of multiple different dimensions required by the sub-node to the node can enable the sub-node to quickly and accurately obtain the communication resources it needs, speed up the communication efficiency of the sub-node, and reduce the cost of the sub-node. The possibility of node failure improves the user experience.
在一些具体实现中，依据网络状态信息确定子节点恢复正常，包括：在确定子节点满足如下条件中至少一种的情况下，确定子节点恢复正常：In some specific implementations, determining that the child node returns to normal based on network status information includes: determining that the child node returns to normal when it is determined that the child node meets at least one of the following conditions:
子节点在第一通信连接中的连接状态为连通；The connection status of the child node in the first communication connection is connected;
子节点的实时业务处理量与子节点的业务处理能力相匹配；The real-time business processing volume of the child node matches the business processing capability of the child node;

通过上述多个条件的不同角度的判断，能够明确子节点所处的通信状态，进而确定该子节点是否恢复正常(例如，恢复至该子节点使用初始配置的网络连接模式进行正常通信的状态等)，从而及时对恢复正常的子节点进行处理，使其与主节点之间的端到端通信的网络连接模式可以恢复至初始配置的网络连接模式，以降低主节点的处理压力，方便主节点释放更多的通信资源，用以对其他故障节点进行处理，减少网络瘫痪的可能性，并提升通信网络的系统稳定性。By judging the above multiple conditions from different angles, the communication state of the child node can be clarified, and then it can be determined whether the child node has returned to normal (for example, returning to a state where the child node uses the initially configured network connection mode for normal communication, etc. ), so as to promptly process the child nodes that have returned to normal, so that the network connection mode of end-to-end communication with the master node can be restored to the initially configured network connection mode, so as to reduce the processing pressure of the master node and facilitate the master node. Release more communication resources to handle other faulty nodes, reduce the possibility of network paralysis, and improve the system stability of the communication network.

This network switching method can be applied to network switching sub-nodes. As shown in Figure 4, the network switching method in the embodiment of the present application includes but is not limited to the following steps.
步骤S401，向主节点发送子节点的网络状态信息。Step S401: Send the network status information of the child node to the master node.
其中，网络状态信息为表征子节点发生故障的信息。例如，子节点发生通信连接中断的故障，或子节点发生网络拥塞的故障，或子节点所获得的配置信息异常的故障等等。以上对于子节点发生的故障的类型仅是举例说明，可根据实际情况进行具体处理，其他未说明的子节点发生的故障的类型也在本申请实施例的保护范围之内，在此不再赘述。Among them, the network status information is information indicating the failure of a child node. For example, the communication connection of the sub-node is interrupted, or the sub-node suffers from network congestion, or the configuration information obtained by the sub-node is abnormal, etc. The above are only examples of the types of faults that occur in child nodes, and specific processing can be carried out according to actual conditions. Other unexplained types of faults that occur in child nodes are also within the protection scope of the embodiments of this application and will not be described again here. .
通过将子节点发生故障的信息发送给主节点，能够使主节点及时准确的获知该子节点存在异常，并快速对该子节点进行故障处理，从而使该子节点的通信能够快速回复正常，减少因通信中断而导致的用户体验不佳的比例，提升网络切换子节点与网络切换主节点之间的通信稳定性。By sending the failure information of the child node to the master node, the master node can promptly and accurately learn that the child node is abnormal, and quickly handle the fault of the child node, so that the communication of the child node can quickly return to normal, reducing The proportion of poor user experience caused by communication interruptions improves the communication stability between network switching sub-nodes and network switching master nodes.
步骤S402，响应于主节点发送的第一切换消息，将子节点的网络连接模式切换为支持端到端通信的网络连接模式。Step S402: In response to the first switching message sent by the master node, switch the network connection mode of the child node to a network connection mode that supports end-to-end communication.
其中，第一切换消息是用于指示子节点进行通信网络连接模式的切换的消息。The first switching message is a message used to instruct the child node to switch the communication network connection mode.
因在获得第一切换消息之前，主节点与子节点之间的通信连接是基于非端到端的通信连接(如，基于Mesh网络的通信连接等)，若该子节点的通信中断，会使与该子节点相连接的其他设备的通信受到影响(例如，无法及时获得主节点的配置信息，或，获取到的主节点发送的信息为错误信息等)；通过将子节点的网络连接模式切换为支持端到端通信的网络连接模式，能够使该子节点可以直接与主节点进行通信，加快从主节点获取信息的速度；还能够使该子节点通过与主节点之间的通信信息的转发，使该子节点与其他设备进行通信，减少通信网络瘫痪的可能性，从而提升通信网络的系统稳定性。Because before the first switching message is obtained, the communication connection between the master node and the sub-node is based on a non-end-to-end communication connection (such as a communication connection based on a Mesh network, etc.). If the communication with the sub-node is interrupted, the communication connection with the sub-node will be interrupted. The communication of other devices connected to the child node is affected (for example, the configuration information of the master node cannot be obtained in time, or the information sent by the master node is error information, etc.); by switching the network connection mode of the child node to The network connection mode that supports end-to-end communication enables the child node to communicate directly with the master node, speeding up the acquisition of information from the master node; it also enables the child node to forward the communication information with the master node, Allow the sub-node to communicate with other devices, reducing the possibility of paralysis of the communication network, thereby improving the system stability of the communication network.

步骤S809，网络切换主节点710根据获得的不同的网络切换子节点发送的网络状态信息，更新子节点状态信息表。Step S809: The network switching master node 710 updates the child node status information table according to the obtained network status information sent by different network switching child nodes.
步骤S810，根据更新后的子节点状态信息表，确定第K子节点72K在第一通信连接中的连接状态信息能够表征第K子节点72K与网络切换主节点710之间的第一通信连接恢复正常，则网络切换主节点710生成第二切换消息，并通过第二通信连接，向第K子节点72K发送该第二切换消息。Step S810, according to the updated child node status information table, determine that the connection status information of the K-th child node 72K in the first communication connection can represent the restoration of the first communication connection between the K-th child node 72K and the network switching master node 710. If normal, the network switching master node 710 generates a second switching message and sends the second switching message to the K-th child node 72K through the second communication connection.
步骤S811，第K子节点72K在接收到第二切换消息后，将其与网络切换主节点710之间的通信连接方式由第二通信连接切换为第一通信连接；并基于第一通信连接，第K子节点72K与网络切换主节点710进行通信。Step S811, after receiving the second switching message, the K-th child node 72K switches the communication connection mode with the network switching master node 710 from the second communication connection to the first communication connection; and based on the first communication connection, The Kth child node 72K communicates with the network switching master node 710.
在本实施例中，通过网络切换主节点710与多个网络切换子节点之间建立第一通信连接和第二通信连接，并使网络切换主节点710能够对多个网络切换子节点在第一通信连接中的连接状态信息进行监测，能够实时准确的确定各个网络切换子节点是否发生故障；在确定某个子节点与网络切换主节点710之间的第一通信连接处于中断状态的情况下，能够及时将该子节点与网络切换主节点710之间的通信连接切换至第二通信连接，保证该子节点仍然可以通过第二通信连接方式，与其他节点进行通信(如，直接与网络切换主节点710进行基于第二通信连接的通信，或，通过网络切换主节点710的转发，与其他节点进行通信等)，可降低因子节点发生故障而导致的其他节点无法进行通信的故障比例。并且，在检测到故障子节点在第一通信连接中的连接状态信息能够表征第K子节点72K与网络切换主节点710之间的第一通信连接恢复正常，再将该故障子节点由第二通信连接切换回第一通信连接，能够适时切换到不同的可用的网络模式(如，将WiFi-P2P网络连接作为Mesh网络连接的备用通信连接)，减少网络瘫痪的可能性，并提升通信网络的系统稳定性。In this embodiment, the first communication connection and the second communication connection are established between the network switching master node 710 and multiple network switching sub-nodes, so that the network switching master node 710 can communicate with the multiple network switching sub-nodes in the first Monitoring the connection status information in the communication connection can accurately determine whether each network switching sub-node fails in real time; when it is determined that the first communication connection between a certain sub-node and the network switching master node 710 is in an interrupted state, it can Timely switch the communication connection between the child node and the network switching master node 710 to the second communication connection to ensure that the child node can still communicate with other nodes through the second communication connection method (for example, directly with the network switching master node 710 performs communication based on the second communication connection, or switches the forwarding of the master node 710 through the network to communicate with other nodes, etc.), which can reduce the failure ratio of other nodes that are unable to communicate due to failure of the sub-node. Moreover, after detecting that the connection status information of the faulty sub-node in the first communication connection can indicate that the first communication connection between the K-th sub-node 72K and the network switching master node 710 is restored to normal, the faulty sub-node is then replaced by the second communication connection. The communication connection is switched back to the first communication connection and can be switched to different available network modes in a timely manner (for example, using the WiFi-P2P network connection as a backup communication connection for the Mesh network connection), reducing the possibility of network paralysis and improving the performance of the communication network. System stability.
