[0055] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0056] The network upgrade method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The server 104 obtains the upgrade instruction received by the master node; determines the node to be upgraded according to the node system status of each child node under the network corresponding to the master node; upgrades the node to be upgraded according to the upgrade instruction and the parent-child node relationship of the network to obtain the upgrade result; when the upgrade result is that the nodes to be upgraded have completed the upgrade, the master node is upgraded according to the upgrade instruction. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc., and different nodes can be the same terminal device or different terminal devices. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head mounted device may be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The server 104 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0057] In an exemplary embodiment, Figure 2 As shown, a network upgrade method is provided, which is applied to Figure 1 The server 104 in the example is used as an example to illustrate, including the following steps 202 to 208. Among them:

[0058] Step 202: Obtain the upgrade instruction received by the master node.

[0059] The master node is the main control device of the entire network, used to exchange data and information with the outside world, and control the upgrade of internal sub-nodes. The sub-nodes of the next level are connected to the master node, and different nodes can be the same terminal device or different terminal devices. The upgrade instructions received by the master node are sent by the external communication link, and the external communication link is only deployed in the master node of the network.

[0060] In some embodiments, after the upgrade instruction is issued externally, the upgrade instruction including the upgrade package can be sent to the master node through the external communication link deployed in the master node, so as to obtain the upgrade instruction received by the master node, but it is not limited thereto.

[0061] Step 204, determining the node to be upgraded according to the node system status of each sub-node in the network corresponding to the master node.

[0062] The node system status is status data used to determine the current node operation status. The status data can be used to indicate that the node system status is abnormal, or that the current node is in an upgradeable state, etc., but is not limited thereto.

[0063] In some embodiments, based on the node system status of each sub-node under the network corresponding to the master node, when the node system status of all sub-nodes under the network is in an upgradeable state, the master node sends instructions to gradually determine all sub-nodes under the network as nodes to be upgraded, and switch the node system status of the nodes to be upgraded to an upgraded state, thereby ensuring that the nodes to be upgraded can complete the upgrade more efficiently.

[0064] Step 206: upgrade the node to be upgraded according to the upgrade instruction and the parent-child node relationship of the network to obtain an upgrade result.

[0065] Among them, the parent-child node relationship of the network refers to the connection relationship between the nodes between the upper and lower levels in the networking structure of the network. The networking structure can adopt a tree structure with one master and multiple slaves. It should be noted that each node in the tree structure is only responsible for the upper and lower adjacent nodes. Therefore, the device types of each node can be different, and the number of devices under the entire network can be expanded. The communication link between nodes is irrelevant to the entire network. When expanding, the device to be added can be used as a child node that can directly establish a communication node. After the node is added, the same upgrade module is deployed, and the processing flow of each child node is the same, and the code is reused to achieve a more flexible and easy-to-expand leaf node upgrade. Different topologies can also be used, such as star, ring, bus, mesh, and hybrid. Among them, the hybrid can be a combination of tree and star, but is not limited to this.

[0066] In some embodiments, the node to be upgraded is upgraded according to the upgrade instruction and the parent-child node relationship of the network to obtain an upgrade result, including: determining the version upgrade data according to the upgrade instruction; sending the version upgrade data step by step to the non-running partition of the node to be upgraded according to the parent-child node relationship to upgrade the non-running partition of the node to be upgraded to obtain an upgrade result.

[0067] The version upgrade data may be an upgrade package.

[0068] In some embodiments, the upgrade process is triggered according to the upgrade instruction. The upgrade process can support multiple upgrade methods, such as OTA, proximal tools, SD cards, etc., to determine the version upgrade data according to the upgrade instruction, and send the version upgrade data step by step to the non-running partitions of the nodes to be upgraded according to the parent-child node relationship, so as to upgrade the non-running partitions of the nodes to be upgraded and obtain the upgrade results, thereby realizing an efficient and adaptable upgrade process for the nodes to be upgraded.

[0069] It should be noted that in the networking, each node to be upgraded is set to internally support AB partitions, which only treats the non-running partitions of the nodes to be upgraded, and does not affect the operation of the current partition system program of the nodes to be upgraded. When the upgrade of the non-running partition of the node to be upgraded fails, it means that the current upgrade has an exception. Since the partition upgrade does not affect the normal operation of the running area, no additional processing is required, and only waiting for the next upgrade is required, thereby ensuring the version availability of each node to be upgraded in abnormal scenarios.

[0070] Step 208: When the upgrade result shows that all nodes to be upgraded have completed the upgrade, the master node is upgraded according to the upgrade instruction.

[0071] Among them, whether the node to be upgraded has completed the upgrade is returned by the node to be upgraded. The heartbeat monitoring can monitor the communication status of all nodes in the network to ensure that the communication disconnection between nodes during the upgrade process can be perceived and processed in time.

[0072] In some embodiments, when the upgrade result is that all nodes to be upgraded have completed the upgrade, the master node is upgraded according to the upgrade instruction, which means that the upgrade order of each node in the network is to set the networking upgrade order to give priority to upgrading the nodes to be upgraded as leaf nodes. After all nodes to be upgraded are successfully upgraded, the parent node corresponding to the node to be upgraded starts to upgrade until all nodes to be upgraded under the master node are successfully upgraded, and then the master node is upgraded according to the upgrade instruction. After the master node is upgraded, the entire upgrade process is completed.

[0073] It should be noted that in the initial upgrade process, the nodes to be upgraded, which are leaf nodes, can be upgraded at the same time. After the upgrade of the nodes to be upgraded is completed, the parent node corresponding to the nodes to be upgraded waits for all the child nodes under it to complete the upgrade before starting the upgrade of this node. The parallel execution of the upgrade process ensures the efficiency of the upgrade.

[0074] In some embodiments, after the master node completes the upgrade, the master node publishes the upgrade results and waits for the user's restart instruction. After receiving the restart message, all nodes complete the startup of the new partition program. The startup order is consistent with the upgrade order, and the leaf node is started first, and then the parent node is started.

[0075] In some embodiments, after upgrading the master node according to the upgrade instruction, the method further includes: obtaining a partition cutting instruction; sending the partition cutting instruction to each child node in the network, so that each child node in the network switches to the partition state to be switched.

[0076] In some embodiments, after the master node is upgraded, a partition cutting instruction is obtained, and the master node uniformly sends the partition cutting instruction to the child nodes to prepare the child nodes to switch to the new partition so that the new partition application can be started at the next startup. It should be noted that placing the partition cutting operation after all nodes are successfully upgraded can greatly simplify the exception handling process of errors or power outages during the upgrade process, thereby improving the upgrade efficiency.

[0077] In the above networking upgrade method, the upgrade instruction received by the master node is obtained; the node to be upgraded is determined according to the node system status of each child node under the network corresponding to the master node; the node to be upgraded is upgraded according to the upgrade instruction and the parent-child node relationship of the network to obtain the upgrade result; when the upgrade result is that the nodes to be upgraded have all been upgraded, the master node is upgraded according to the upgrade instruction. Therefore, by determining the node to be upgraded according to the node system status of each child node under the network corresponding to the master node, and upgrading the node to be upgraded according to the upgrade instruction and the parent-child node relationship of the network, the network structure of the network is used to quickly use the child node that is ready to be upgraded as the node to be upgraded, and the node to be upgraded is upgraded first, that is, the communication link between the nodes is independent, and the parent-child node relationship of the network can be used to quickly upgrade multiple child nodes at the same time, thereby improving the efficiency of the upgrade, and when the upgrade result is that the nodes to be upgraded have all been upgraded, the master node is upgraded according to the upgrade instruction, so that each child node under the network can be rolled back in the event of an upgrade interruption, thereby achieving a simple overall processing logic while ensuring the reliability of the upgrade.

[0078] In an exemplary embodiment, Figure 3As shown, before determining the node to be upgraded according to the node system status of each sub-node in the network corresponding to the master node, the network upgrade method further includes a system status check step, and the system status check step includes steps 302 to 304. Among them:

[0079] Step 302: Perform a system status check on the sub-node according to the networking structure of the network to obtain a check result.

[0080] Among them, the system status check is a status check process implemented by issuing check instructions step by step according to the networking structure of the network.

[0081] In some embodiments, inspection instructions are issued to child nodes according to the networking structure of the network, and the child nodes in turn issue inspection instructions to corresponding child nodes, and the node system status of each child node is checked step by step. When the system status of a node is abnormal, the inspection result is that the system status is abnormal. When all nodes are in an upgradeable state, the inspection result is that the child node is in an upgradeable state.

[0082] Step 304: When the inspection result indicates that the child node is in an upgradeable state, a state switching instruction is generated according to the inspection result, so that the child node switches the current node state to an upgrade state.

[0083] The upgrade status refers to the current subnode being in the upgrade status.

[0084] In some embodiments, when the inspection result indicates that the child node is in an upgradeable state, that is, when all the child nodes are currently in an upgradeable state, the master node will generate a state switching instruction based on the inspection result, and send it down to all child nodes step by step to switch the current node state of the child node to an upgrade state, thereby ensuring the efficient implementation of the subsequent upgrade process.

[0085] In some embodiments, after the child node switches the current node state to an upgraded state, the method further includes: generating heartbeat information according to the heartbeat timer of the master node; and sending the heartbeat information to the child node so that the child node responds to the heartbeat information.

[0086] The heartbeat timer is a timer that continuously sends heartbeat information according to a timing cycle.

[0087] In some embodiments, after the child node switches the current node state to the upgrade state, the parent node corresponding to the current child node will start a heartbeat timer to send a heartbeat message to the child nodes under it. After the child node receives the heartbeat message, the child node will determine whether the heartbeat state of other child nodes currently under it is normal, and respond to the heartbeat message sent by the parent node. If all child nodes have sent a normal heartbeat message, after the parent node receives the normal heartbeat message, the heartbeat function is set to normal, and wait for the next heartbeat message to be sent and check the timing period. If no heartbeat message is received within the period or a heartbeat abnormality message is received, the heartbeat abnormality result is returned step by step, and the timer is ended. When the root node receives a heartbeat abnormality, the child node is controlled to end the upgrade state and return an error message to the outside, thereby ensuring the normal communication function between nodes during the upgrade process.

[0088] In some embodiments, after the child node switches the current node state to an upgraded state, the method further includes: obtaining version information of the upgraded child node in the upgraded state; in the event that the upgrade state of the upgraded child node is interrupted, performing version rollback processing on the completed child node that has completed the upgrade according to the version information.

[0089] The upgrade status interruption may be caused by a power failure in any upgrade status of any node during the upgrade process.

[0090] In some embodiments, after the child node switches the current node state to the upgrade state, the master node records the version information of the upgrade child node currently in the upgrade state, thereby obtaining the version information. When the power is cut off during the upgrade process (regardless of which node or which upgrade state it is in), resulting in the interruption of the upgrade state of the upgrade child node, the program can be restarted to perform version rollback processing on the completed child node that has completed the upgrade according to the version information, accurately determine the current system state and roll back the version according to the version information, thereby achieving consistency of all versions under the unified networking with those before the upgrade.

[0091] In order to understand the solution of this application more clearly, Figure 4 , Figure 5 , Figure 6 and Figure 7 The details are as follows:

[0092] first, Figure 4 The figure shows that the network structure in the tree-type network is a tree topology, in which the upgrade function of each node is performed in sequence according to the level, and the leaf nodes in the tree-type network can be flexibly expanded.

[0093] Secondly, in Figure 5 The interaction flow chart between nodes in the tree network is shown in Figure 6 The main modules and Figure 7The timing example diagram shown in the figure can more clearly show a complete specific implementation process.

[0094] Specifically, in Figure 5 The interaction process between nodes in one branch of the tree network is shown in Figure 5 There are six interactive steps ①②③④⑤⑥ shown in the figure, among which:

[0095] ① The process of the current node receiving the parent node upgrade instruction. If the current node is the root node, the instruction currently received is the external instruction.

[0096] ②③ is the process of the current node sending instructions to the child nodes;

[0097] ④⑤ is the process of receiving instructions and executing upgrades for the child node, and returning the upgrade results to the current node;

[0098] ⑥ is the process of returning the results to the parent node after the current node is upgraded.

[0099] In addition, Figure 6 The connection relationship of each module in an exemplary embodiment is shown in FIG. Figure 6 The functions of each module are as follows:

[0100] Communication module: used for internal interaction between nodes. The root node also includes external communication.

[0101] System state conversion module: When the upgrade is triggered, the entire ECU is converted from the running state to the upgrading state. Other business modules sense the upgrade system status, start and stop the business as needed, and then execute the upgrade;

[0102] Heartbeat monitoring module: During the upgrade of multiple device nodes, the communication status of all nodes in the entire network is monitored through the heartbeat monitoring module to ensure timely perception and processing of abnormalities;

[0103] Upgrade installation module: realizes functions such as processing upgrade packages, writing upgrade images, and partition switching;

[0104] Finally, in Figure 7 The simplified upgrade sequence diagram is shown in Figure 1, which mainly explains that after the user issues an upgrade request, this solution will send the upgrade instruction to Figure 7 Node 1 in the system is selected as the root node, and then nodes 2 and 3 are upgraded in parallel by issuing instructions step by step. Node 2 is the parent node of node 4, and node 2 will be upgraded only after node 4 is upgraded. Finally, after nodes 2 and 3 are upgraded, root node 1 is upgraded, and the upgrade result of this upgrade is returned to the user.

[0105] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0106] Based on the same inventive concept, the embodiment of the present application also provides a network upgrade device for implementing the network upgrade method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more network upgrade device embodiments provided below can refer to the limitations on the network upgrade method above, and will not be repeated here.

[0107] In an exemplary embodiment, Figure 8 As shown, a network upgrade device 800 is provided, including: an acquisition module 801, a node determination module 802, a first upgrade module 803 and a second upgrade module 804, wherein:

[0112] In some embodiments, the first upgrade module 803 is also used to determine version upgrade data according to the upgrade instruction; and send the version upgrade data step by step to the non-running partition of the node to be upgraded according to the parent-child node relationship, so as to upgrade the non-running partition of the node to be upgraded and obtain the upgrade result.
