[0012] In some implementations, the data entry unit is further configured to, in response to receiving the pre-written log copy from the plurality of monitoring service nodes, read the target power monitoring data marked with the first data state from the pre-written log copy, and write the target power monitoring data into a local database.

[0013] In some embodiments, the apparatus further includes: The heartbeat broadcasting unit is configured to broadcast heartbeat messages through each of the slave monitoring service nodes at their respective preset time intervals when it is determined that the main monitoring service node has failed.

[0021] The ship power monitoring data processing method of this application embodiment, in response to a data write request for target power monitoring data, stores the target power monitoring data in a pre-written log file and marks the target power monitoring data as a first data state, indicating that it has not been written to the database. The target power monitoring data indicates the power parameters of the ship's power system. Then, the main monitoring service node generates a pre-written log copy based on the pre-written log file and sends the pre-written log copy to multiple slave monitoring service nodes. When it is determined that the number of slave monitoring service nodes receiving the pre-written log copy meets a preset condition, the main monitoring service node writes the target power monitoring data in the pre-written log file to the local database and marks the target power monitoring data in the pre-written log file as a second data state indicating that it has been written to the database. This multi-node elastic writing method of "log first, data later" avoids the problem of data loss caused by the failure of a single node during the writing process, ensuring that even if an anomaly occurs during operation, fault recovery can be performed based on the pre-written log file, thus improving the reliability and data consistency of ship power monitoring data processing.

In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0030] Please see Figure 1 The diagram illustrates a flowchart of a ship power monitoring data processing method provided in this application. This method can be applied to a ship power system monitoring service cluster, which includes multiple monitoring service nodes that can provide monitoring services for the ship power system. Specifically, the multiple monitoring service nodes include a master monitoring service node and multiple slave monitoring service nodes.

[0031] It should be noted that the nodes mentioned in the embodiments of this application can be servers. The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.

[0032] It should be noted that this specification provides the operational steps of the methods described in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operational steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only execution order. In actual system or product execution, the methods shown in the embodiments or drawings can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown... Figure 1 As shown, the ship dynamics monitoring data processing method may include: S101, in response to the data write request for the target power monitoring data by the main monitoring service node, the target power monitoring data is stored in the pre-written log file and the target power monitoring data is marked as the first data state.

[0033] The first data status indication is not written to the database. The target power monitoring data can indicate the system parameters of the monitored ship power system.

[0034] S103, the master monitoring service node generates a write-ahead log copy based on the write-ahead log file and sends the write-ahead log copy to the multiple slave monitoring service nodes.

[0035] S105, if the number of slave monitoring service nodes that have received the write-ahead log copy meets a preset condition, the target power monitoring data in the write-ahead log file is written to the local database through the master monitoring service node, and the target power monitoring data in the write-ahead log file is marked as a second data status, the second data status indicating that it has been written to the database.

[0036] The preset condition can be that more than half of the slave monitoring service nodes receive the write-ahead log copy. For example, if the total number of slave monitoring service nodes is 5, then the preset condition can be that the number of slave monitoring service nodes receiving the write-ahead log copy is greater than or equal to 3. Therefore, when 3 slave monitoring service nodes receive the write-ahead log copy, the target power monitoring data in the write-ahead log file can be written to the local database of the master monitoring service node through the master monitoring service node.

[0037] It should be noted that in this embodiment, the primary monitoring service node can be determined through a flexible competition mechanism. Specifically, each monitoring service node in the marine power system monitoring service cluster possesses complete candidate node capabilities, including a unique node identifier, a complete operating environment, and healthy equipment and network status. Each monitoring service node sets a broadcast heartbeat message transmission interval, which can be a random number, typically 1 to 3 seconds. Based on this interval, each time the marine power system monitoring service cluster powers on, the monitoring service node that first broadcasts a heartbeat message becomes the primary monitoring service node. Other monitoring service nodes automatically set their node status to slave node upon receiving the heartbeat message from the primary monitoring service node. Thus, the multiple monitoring service nodes other than the primary monitoring service node are referred to as multiple slave monitoring service nodes.

[0038] The above implementation method avoids data loss caused by the failure of a single node to be written to the database in the event of a single node failure during the writing process. It ensures that even if an anomaly occurs during operation, fault recovery can be performed based on the pre-written log file, thereby improving the reliability and data consistency of ship power monitoring data processing.

[0039] In some implementations, the method may further include: In response to receiving the pre-written log copy, the multiple monitoring service nodes read the target power monitoring data marked as the first data state from the pre-written log copy and write the target power monitoring data into the local database.

[0040] Understandably, after the monitoring service node writes the target power monitoring data to the local database, it can mark the target power monitoring data in the write-ahead log copy as a second data state indicating that it has been written to the database, thereby ensuring data consistency between the master monitoring service node and the slave monitoring service node.

[0041] In some implementations, please refer to Figure 2 The diagram shown is a flowchart illustrating another method for processing ship power monitoring data provided in this application embodiment. Figure 2 As shown, the method may further include: S201, if it is determined that the main monitoring service node has failed, each of the slave monitoring service nodes broadcasts a heartbeat message at its own preset time interval.

[0042] For example, the primary monitoring service node can send heartbeat messages to each secondary monitoring service node at preset time intervals. If multiple secondary monitoring service nodes do not receive a heartbeat message from the primary monitoring service node, the primary monitoring service node is determined to be faulty. The preset time interval can be set based on practical experience, for example, it can be a random number interval of 1 to 3 seconds. Specifically, the primary monitoring service node can be determined to be faulty if more than half of the secondary monitoring service nodes do not receive a heartbeat message from the primary monitoring service node, or it can be determined to be faulty if all secondary monitoring service nodes do not receive a heartbeat message from the primary monitoring service node, thereby improving the accuracy of fault determination.

[0043] The preset time interval for broadcasting heartbeat messages by each monitoring service node can be the same or different. In this embodiment, the preset time interval for broadcasting heartbeat messages by each monitoring service node is the same, and can be a random number of 1 to 3 seconds.

[0044] S203, based on the heartbeat message broadcast results of each of the slave monitoring service nodes, determine a new master monitoring service node from the plurality of slave monitoring service nodes.

[0045] The new master monitoring service node is the slave monitoring service node that first sends heartbeat messages to other slave monitoring service nodes. The heartbeat message broadcast results of each slave monitoring service node indicate whether the corresponding slave monitoring service node's heartbeat message has been sent to other slave monitoring service nodes, and the order in which they were sent.

[0046] S205, the version information of the write-ahead log copy is updated through the new master monitoring service node, and the updated version of the write-ahead log copy is synchronized to the remaining slave monitoring service nodes.

[0047] Specifically, the version information of the write-ahead log replica can increment with the number of times the primary monitoring service node is switched. That is, the version of the write-ahead log replica increases by 1 each time the primary monitoring service node is switched. After the new primary monitoring service node updates the version information of the write-ahead log replica, it synchronizes the latest version of the write-ahead log replica to the remaining secondary monitoring service nodes, thereby ensuring the data consistency of the remaining monitoring service nodes.

[0048] In some implementations, the method may further include: the new master monitoring service node carrying a log index marker in a heartbeat message sent to the slave monitoring service node, the log index marker indicating the latest updated log index; the slave monitoring service node obtaining the log index marker from the heartbeat message and writing the log record corresponding to the log index marker in the latest version of the write-ahead log copy to a local database.

[0049] Specifically, after the new master monitoring service node synchronizes the latest version of the write-ahead log copy to the remaining slave monitoring service nodes, the new master monitoring service node can carry a log index marker in the heartbeat message sent to the slave monitoring service nodes. This log index marker indicates the latest updated log index, so each slave monitoring service node can obtain the log index marker from the received heartbeat message and write the log record corresponding to the log index marker in the latest version of the write-ahead log copy to the local database, further improving the data consistency between different monitoring service nodes.

[0050] In some implementations, please refer to Figure 3 The diagram shown is a flowchart illustrating another method for processing ship power monitoring data provided in this application embodiment. Figure 3 As shown, before step S101, the method may further include: S301, Based on a redundant communication network structure, a network communication link is constructed between each monitoring service node in the ship power system monitoring service cluster; the redundant communication network structure includes a ring network and a dual-star network.

[0051] Specifically, Turbo Ring and Turbo Chain technologies can be used to form a redundant ring network of monitoring service nodes. Based on this, the network can be connected through inter-ring coupling to achieve maximum network redundancy. As long as there is a physical path between two sites, communication between the sites can be guaranteed.

[0052] S303, determine the current communication transmission link based on the constructed network communication link.

[0053] Specifically, the current communication transmission link can be any of the redundant communication network structures, and can be configured based on actual needs. The various monitoring service nodes of the ship propulsion system monitoring service cluster can communicate through the current communication transmission link.

[0054] The above implementation method enables the ship power system monitoring service cluster to have redundant communication capabilities. After the current communication transmission link is disconnected, it can switch to another link, realizing high availability connection between multiple communication paths. This ensures that data transmission is not interrupted in the event of a failure of a certain communication path, thereby improving the stability and reliability of ship power monitoring data processing.

[0055] See also Figure 3 After step S303, the method may further include: S305, monitor the link status of the current communication transmission link and obtain the current link status monitoring result.

[0056] S307, if the current link status monitoring result indicates that the link is abnormal, the communication transmission link is switched based on the constructed network communication link.

[0057] Specifically, the current link status of a communication transmission link can be characterized by key parameters such as network status, latency, and packet loss. The current link status monitoring result indicates whether the link is abnormal. This is achieved by comparing the monitored key parameters of the current communication transmission link with preset threshold parameters, such as a packet loss rate threshold. If the packet loss rate of the current communication transmission link is greater than or equal to the threshold, a current link status monitoring result indicating an abnormal link is generated; conversely, if the packet loss rate is less than the threshold, a current link status monitoring result indicating a normal link is generated.

[0058] In this embodiment of the application, when the current link status monitoring result indicates that the link is abnormal, the communication transmission link is switched based on the network communication link constructed in the aforementioned step S301. This enables seamless communication transmission link switching within milliseconds, ensuring high reliability and service continuity of the communication link.
