Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to an industrial communication management method, system, and storage medium. Background Technology

[0002] With the deepening development of intelligent manufacturing, modern industrial systems are becoming increasingly complex and networked. A typical industrial system often contains multiple devices that exchange data through diverse communication protocols and interfaces. To ensure the continuity, stability, and efficiency of the production process, the communication network of an industrial system must possess sufficient reliability and real-time performance. Currently, most industrial systems are deployed by engineers who statically configure communication protocols, interfaces, and parameters based on equipment models and network topology. When communication failures occur, the system typically only provides limited alarms and cannot automatically perform effective recovery operations. Troubleshooting and recovery heavily rely on manual intervention, resulting in slow response times, potential production interruptions, and economic losses.

[0003] Meanwhile, the system cannot proactively perceive and adapt to available communication interfaces and protocols during startup or runtime, lacking dynamic awareness of the communication environment. When the preset primary communication path becomes unavailable, the system cannot autonomously switch to an available backup path, leading to a communication deadlock. Even if the communication connection remains open, the system typically does not continuously monitor communication quality. When communication quality deteriorates to the point of affecting control performance due to interference, excessive load, or other reasons, the system cannot proactively trigger communication protocol switching or parameter optimization; it can only react passively after severe quality degradation leads to functional failure. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art.

Based on the switching cost information, a communication protocol switching analysis is performed to determine the communication protocol that the industrial system needs to switch to.

[0010] Optionally, the step of monitoring whether a communication interruption event occurs in the industrial system in real time includes: The system uses a preset heartbeat mechanism to monitor in real time whether communication interruption events occur in the industrial system.

Detailed Implementation

[0018] 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, and 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. Example 1:

[0019] Please see Figure 1 , Figure 1 This is a flowchart illustrating the industrial communication management method according to an embodiment of the present invention. The method includes: S11: Analyze the protocol types of available communication interfaces based on the hardware detection program to obtain protocol type information, construct a protocol priority list based on the protocol type information, and establish a network communication connection for the industrial system based on the protocol priority list. In a specific implementation of this invention, the step of analyzing the protocol types of available communication interfaces based on a hardware detection program to obtain protocol type information, and constructing a protocol priority list based on the protocol type information, includes: analyzing the protocol types of each available communication interface using a hardware abstraction layer based on a hardware detection program to obtain protocol type information; performing a real-time requirement score based on the protocol type information to obtain real-time requirement score information; performing a security score based on the protocol type information to obtain security score information; performing a compatibility score based on the protocol type information to obtain compatibility score information; and constructing a protocol priority list based on the real-time requirement score information, security score information, and compatibility score information.

[0020] Specifically, the hardware detection program uses the hardware abstraction layer to analyze the protocol types of each available communication interface to obtain protocol type information. The system automatically executes the hardware detection process during the framework initialization phase. First, it scans all available communication interfaces to identify the currently available protocol types.

[0021] Based on the protocol type information, a real-time requirement score is performed to obtain real-time requirement score information. The typical cycle time and data transmission delay fluctuation range corresponding to the protocol type information of available communication interfaces are retrieved from the database. The typical cycle time is the minimum, standard, or typical data exchange cycle time supported by the protocol. The data transmission delay fluctuation range is the difference between the maximum and minimum data transmission delay values. A first benchmark value for the typical cycle time and a second benchmark value for the data transmission delay fluctuation range are obtained. The quotient of the typical cycle time and the first benchmark value are calculated, and the quotient of the data transmission delay fluctuation range and the second benchmark value are calculated. Combining these two values ​​yields the real-time requirement score. Based on the protocol type information, a security score is performed to obtain the encryption algorithm strength of the protocol type information. The encryption algorithm strength is then scored according to preset scoring rules to obtain security score information, such as the security score of the AES-256 algorithm being higher than that of the AES-128 algorithm.

[0022] Compatibility scoring is performed based on the protocol type information to obtain compatibility score information, which is the proportion of devices in the network that support the protocol. The higher the proportion, the higher the score. A protocol priority list is constructed based on the real-time requirement score, security score, and compatibility score information. This can be achieved by weighting the real-time requirement score, security score, and compatibility score information to obtain the target score for the protocol type: Target Score = W1 * Real-time Score + W2 * Security Score + W3 * Compatibility Score, where W1, W2, and W3 are weight coefficients corresponding to different scores. These weight coefficients are matched in the database and sorted in descending order of the target score to generate the protocol priority list.

[0023] The system establishes network communication connections for the industrial system based on the aforementioned protocol priority list. Connections are attempted sequentially according to protocol priority, with the system prioritizing the highest-priority protocol. Once a connection is successfully established, the system immediately sets it as the currently used protocol and logs the successful connection. This automatic detection mechanism ensures that the system can quickly establish optimal communication connections after power-on. For example, if TCP / IP has the highest priority, Modbus RTU has the second highest priority, and RS232 has the lowest priority, then TCP / IP will be the first protocol to be connected.

[0024] Furthermore, the step of using the hardware abstraction layer to analyze the protocol type of each available communication interface based on the hardware detection program to obtain protocol type information includes: using the hardware abstraction layer to analyze the bus data frame of each available communication interface based on the hardware detection program to obtain bus data frame information; and using the bus data frame information to analyze the protocol type of each available communication interface to obtain protocol type information.

[0025] Specifically, the hardware detection program uses the hardware abstraction layer to analyze the bus data frames of each available communication interface to obtain bus data frame information. The system enumerates all physical interfaces through the unified API of the hardware abstraction layer, enables promiscuous mode on the interface, and captures the original data frames to obtain the bus data frame information.

[0026] Based on the bus data frame information, the protocol type of each available communication interface is analyzed to obtain the protocol type information. The obtained bus data frame information is then compared with the built-in protocol feature library to obtain the matching protocol type.

[0027] S12: After establishing network communication connections for the industrial system, perform communication quality analysis on the industrial system to obtain communication quality information; In the specific implementation of this invention, the step of performing communication quality analysis on the industrial system to obtain communication quality information includes: performing communication environment characteristic analysis on the industrial system to obtain communication environment characteristic information; performing signal transmission speed analysis on the industrial system based on a preset time granularity to obtain signal transmission speed information; performing signal strength analysis on the industrial system to obtain signal strength information; and determining communication quality information based on the communication environment characteristic information, signal transmission speed information, and signal strength information.

[0028] Specifically, after establishing network communication connections in the industrial system, a communication environment characteristic analysis is performed to obtain communication environment characteristic information. The driver interface is called to read the signal-to-noise ratio (SNR), co-channel interference intensity, and channel busy / idle ratio of available signals in the industrial system. The SNR is the signal strength minus the noise floor. The co-channel interference intensity is used to identify the signal strength of non-cooperative networks. The channel busy / idle ratio is the percentage of time the channel is in a busy state. The background noise level in the industrial system is also read. The communication environment characteristic information is composed of the background noise level, SNR, co-channel interference intensity, and channel busy / idle ratio.

[0029] The signal transmission speed of the industrial system is analyzed based on a preset time granularity to obtain signal transmission speed information. Timestamped probe packets are sent to the industrial system at the preset time granularity, such as once per second. The average round-trip delay and delay standard deviation are calculated based on the sent probe packets, and the signal transmission speed is determined based on the average round-trip delay and delay standard deviation.

[0030] Signal strength analysis is performed on the industrial system to obtain signal strength information. The received signal strength indication and signal-to-noise ratio (SNR) of the industrial system are read, and the signal strength of the industrial system is evaluated based on these indicators. Communication quality information is determined based on the communication environment characteristics, signal transmission speed, and signal strength information. These factors are then input into the evaluation model to obtain a quantified communication quality level.

[0031] S13: Perform communication protocol switching analysis based on the communication quality information to obtain the communication protocol switching analysis results; In a specific implementation of the present invention, the step of performing communication protocol switching analysis based on the communication quality information to obtain the communication protocol switching analysis result includes: determining whether the communication quality information has reached a preset trigger condition; if it is determined that the communication quality information has reached the preset trigger condition, then performing a communication protocol switching cost analysis on the industrial system to obtain switching cost information; and performing communication protocol switching analysis based on the switching cost information to determine the communication protocol that the industrial system needs to switch to.

[0032] Specifically, it is determined whether the communication quality information meets the preset trigger condition. If it is determined that the communication quality information does not meet the preset trigger condition, there is no need to switch the communication protocol. If it is determined that the communication quality information meets the preset trigger condition, the trigger condition can be a threshold of the communication quality information. When the communication quality information reaches or exceeds the preset threshold, it is determined that the preset trigger condition has been met. Then, a communication protocol switching cost analysis is performed on the industrial system to obtain switching cost information. The cost dimensions include: service interruption time: the duration of brief communication interruption caused by the switching process; resource consumption: memory / CPU usage and bandwidth requirements of the new protocol stack; functional loss: functional degradation that may occur when switching from a high-performance protocol to a low-performance protocol; security renegotiation overhead: additional latency will be introduced if a TLS session needs to be re-established. A cost value is evaluated for each cost dimension. The cost value evaluation can be determined by the evaluation rules preset by the management personnel. The cost values ​​of each cost dimension are weighted and summed to obtain the switching cost information.

[0033] Based on the switching cost information, communication protocol switching analysis is performed to determine the communication protocol that the industrial system needs to switch to. The protocol with the lowest switching cost is switched first. By monitoring communication quality parameters in real time, the system can perform preventative protocol switching, taking action in advance before communication quality deteriorates. The system also has a graceful degradation function to ensure that basic communication capabilities are maintained even in harsh network environments.

[0034] S14: After establishing a network communication connection for the industrial system, monitor in real time whether a communication interruption event occurs in the industrial system. If a communication interruption event is detected, match a communication reconnection strategy based on the communication interruption event. The industrial system performs fault recovery based on the communication reconnection strategy and records the target data of the fault recovery process. In the specific implementation of this invention, the step of monitoring whether a communication interruption event occurs in the industrial system in real time includes: monitoring whether a communication interruption event occurs in the industrial system in real time based on a preset heartbeat mechanism.

[0035] Specifically, after establishing a network communication connection for the industrial system, a preset heartbeat mechanism is used to monitor in real time whether a communication interruption event occurs in the industrial system, such as periodically (e.g., every second) sending application-layer survival messages. If N consecutive messages are lost (e.g., 3 times), it is determined to be an interruption. If no communication interruption event is detected in the industrial system, there is no need to match a communication reconnection strategy, and the communication status of the industrial system continues to be monitored.

[0036] Furthermore, the step of matching a communication reconnection strategy based on the communication interruption event, and the industrial system performing fault recovery based on the communication reconnection strategy, includes: performing event type analysis on the communication interruption event to obtain event type information; constructing a communication reconnection strategy library, determining a communication reconnection strategy based on the event type information using the communication reconnection strategy library; determining an operation unit and execution engine based on the communication reconnection strategy, and the industrial system performing fault recovery based on the operation unit and execution engine using the communication reconnection strategy.

[0037] Specifically, if a communication interruption event is detected in the industrial system, an event type analysis is performed on the communication interruption event to obtain event type information. Monitoring data of the industrial system is obtained, such as hardware link status (read directly from the operating system network interface, value 1 indicates link is connected, 0 indicates link is disconnected); heartbeat / polling timeout event (application layer or middleware reports no response from the peer device). The monitoring data is input into a preset diagnostic decision tree, which outputs the event type of the communication interruption event based on the monitoring data. The preset diagnostic decision tree can be a random forest model.

[0038] A communication reconnection policy library is constructed. The policy structure of this library is a tuple of {Conditions, Actions, Metadata} for each policy. Conditions are set based on matching rules such as event type, device role, and interruption duration. Actions define a series of atomic operations. Metadata defines policy priority, timeout, and whether preemption is possible. Based on the event type information, the communication reconnection policy library is used to determine the communication reconnection policy. The event type information is matched against the communication reconnection policy library, and the policy with the highest priority and a perfect match is selected. For example, when a communication interruption is detected, a reconnection operation will first be attempted under the current protocol. The system will set a maximum number of retries to prevent infinite retries. If the current protocol reconnection fails, the system will automatically switch to other available protocols according to a preset priority order. During the switching process, the system will skip the currently failed protocol and try to establish a connection with other available protocols in turn.

[0039] Based on the communication reconnection strategy, operation units and execution engines are determined. Operation units are operation functions corresponding to fault recovery, such as `action_switch_interface()`. The execution engine is a state machine responsible for sequentially and atomically calling the operation units and handling timeouts and failure rollbacks. The industrial system utilizes the operation units and execution engine for fault recovery based on the communication reconnection strategy. The industrial system's execution engine drives the operation units to complete the recovery process of the communication reconnection strategy. Target data of the fault recovery process, such as recovery step timestamps, is recorded.

[0040] S15: Generate target logs based on the target data, communication protocol switching analysis results, communication interruption events, and communication reconnection strategies, and store the target logs in the corresponding nodes.

[0041] In a specific implementation of this invention, the step of generating a target log based on the target data, communication protocol switching analysis results, communication interruption events, and communication reconnection strategies, and storing the target log in the corresponding node, includes: integrating log content based on the target data, communication protocol switching analysis results, communication interruption events, and communication reconnection strategies to obtain the target log; performing encryption strategy analysis on the target log to obtain the target encryption strategy; and storing the target log in the corresponding node based on the target encryption strategy.

[0042] Specifically, based on the target data, communication protocol switching analysis results, communication interruption events, and communication reconnection strategies, log content is integrated, consolidating the scattered target data, communication protocol switching analysis results, communication interruption events, and communication reconnection strategies into a single log event. The target log is obtained by associating all relevant log entries during an interruption or switching process using a unified session_id or correlation_id function.

[0043] The target logs are analyzed for encryption strategies to obtain the target encryption strategy. The sensitivity level of the target logs is identified, and the encryption algorithm for the target logs is determined based on the sensitivity level; this is the target encryption strategy. Based on the target encryption strategy, the target logs are stored in the corresponding nodes. For storage on local or edge nodes, AES-256 symmetric encryption can be used. For uploads to the cloud, asymmetric encryption (such as using the cloud service's public key encryption) can be used. This comprehensive logging mechanism provides complete data support for system maintenance and fault diagnosis.

[0044] In this embodiment of the invention, a hardware detection program analyzes the protocol types of available communication interfaces to obtain protocol type information. Based on this information, a protocol priority list is constructed, and a network communication connection for the industrial system is established. This ensures the system can quickly establish the optimal communication connection. After establishing the network communication connection, communication quality analysis is performed to obtain communication quality information. Based on this information, communication protocol switching analysis is conducted to optimize overall network performance and ensure the service quality of critical services. After establishing the network communication connection, the system monitors in real time for communication interruption events. If an interruption event is detected, a communication reconnection strategy is matched based on the event. The industrial system then performs fault recovery based on this strategy. This three-layer protection mechanism—a protocol priority list, dynamic protocol switching, and intelligent interruption recovery—provides multiple, heterogeneous communication backups for critical control loops and data transmission, significantly enhancing the system's survivability and resilience in complex and harsh industrial environments. Example 2:

[0045] Please see Figure 2 , Figure 2 This is a schematic diagram of the structural composition of the industrial communication management system in an embodiment of the present invention. The system includes: Communication connection establishment module 21: used to perform protocol type analysis on available communication interfaces based on hardware detection program, obtain protocol type information, construct a protocol priority list based on the protocol type information, and establish network communication connection of industrial system based on the protocol priority list; In a specific implementation of this invention, the step of analyzing the protocol types of available communication interfaces based on a hardware detection program to obtain protocol type information, and constructing a protocol priority list based on the protocol type information, includes: analyzing the protocol types of each available communication interface using a hardware abstraction layer based on a hardware detection program to obtain protocol type information; performing a real-time requirement score based on the protocol type information to obtain real-time requirement score information; performing a security score based on the protocol type information to obtain security score information; performing a compatibility score based on the protocol type information to obtain compatibility score information; and constructing a protocol priority list based on the real-time requirement score information, security score information, and compatibility score information.

The data transmission delay fluctuation range is the difference between the maximum and minimum data transmission delay values. A first benchmark value for the typical cycle time and a second benchmark value for the data transmission delay fluctuation range are obtained. The quotient of the typical cycle time and the first benchmark value are calculated, and the quotient of the data transmission delay fluctuation range and the second benchmark value are calculated. Combining these two values ​​yields the real-time requirement score. Based on the protocol type information, a security score is performed to obtain the encryption algorithm strength of the protocol type information. The encryption algorithm strength is then scored according to preset scoring rules to obtain security score information, such as the security score of the AES-256 algorithm being higher than that of the AES-128 algorithm.

[0048] Compatibility scoring is performed based on the protocol type information to obtain compatibility score information, which is the proportion of devices in the network that support the protocol. The higher the proportion, the higher the score. A protocol priority list is constructed based on the real-time requirement score, security score, and compatibility score information. This can be achieved by weighting the real-time requirement score, security score, and compatibility score information to obtain the target score for the protocol type: Target Score = W1 * Real-time Score + W2 * Security Score + W3 * Compatibility Score, where W1, W2, and W3 are weight coefficients corresponding to different scores. These weight coefficients are matched in the database and sorted in descending order of the target score to generate the protocol priority list.

[0049] The system establishes network communication connections for the industrial system based on the aforementioned protocol priority list. Connections are attempted sequentially according to protocol priority, with the system prioritizing the highest-priority protocol.

[0052] Based on the bus data frame information, the protocol type of each available communication interface is analyzed to obtain the protocol type information. The obtained bus data frame information is then compared with the built-in protocol feature library to obtain the matching protocol type.

[0053] Communication quality analysis module 22: used to perform communication quality analysis on the industrial system after establishing network communication connection and obtain communication quality information; In the specific implementation of this invention, the step of performing communication quality analysis on the industrial system to obtain communication quality information includes: performing communication environment characteristic analysis on the industrial system to obtain communication environment characteristic information; performing signal transmission speed analysis on the industrial system based on a preset time granularity to obtain signal transmission speed information; performing signal strength analysis on the industrial system to obtain signal strength information; and determining communication quality information based on the communication environment characteristic information, signal transmission speed information, and signal strength information.

[0054] Specifically, after establishing network communication connections in the industrial system, a communication environment characteristic analysis is performed to obtain communication environment characteristic information.

Communication quality information is determined based on the communication environment characteristics, signal transmission speed, and signal strength information. These factors are then input into the evaluation model to obtain a quantified communication quality level.

[0057] Protocol switching module 23: used to perform communication protocol switching analysis based on the communication quality information and obtain communication protocol switching analysis results; In a specific implementation of the present invention, the step of performing communication protocol switching analysis based on the communication quality information to obtain the communication protocol switching analysis result includes: determining whether the communication quality information has reached a preset trigger condition; if it is determined that the communication quality information has reached the preset trigger condition, then performing a communication protocol switching cost analysis on the industrial system to obtain switching cost information; and performing communication protocol switching analysis based on the switching cost information to determine the communication protocol that the industrial system needs to switch to.

[0058] Specifically, it is determined whether the communication quality information meets the preset trigger condition. If it is determined that the communication quality information does not meet the preset trigger condition, there is no need to switch the communication protocol. If it is determined that the communication quality information meets the preset trigger condition, the trigger condition can be a threshold of the communication quality information.

[0059] Based on the switching cost information, communication protocol switching analysis is performed to determine the communication protocol that the industrial system needs to switch to. The protocol with the lowest switching cost is switched first. By monitoring communication quality parameters in real time, the system can perform preventative protocol switching, taking action in advance before communication quality deteriorates. The system also has a graceful degradation function to ensure that basic communication capabilities are maintained even in harsh network environments.

[0060] Interruption recovery module 24: After establishing a network communication connection for the industrial system, it monitors in real time whether a communication interruption event occurs in the industrial system. If a communication interruption event is detected, it matches a communication reconnection strategy based on the communication interruption event. The industrial system performs fault recovery based on the communication reconnection strategy and records the target data of the fault recovery process. In the specific implementation of this invention, the step of monitoring whether a communication interruption event occurs in the industrial system in real time includes: monitoring whether a communication interruption event occurs in the industrial system in real time based on a preset heartbeat mechanism.

[0061] Specifically, after establishing a network communication connection for the industrial system, a preset heartbeat mechanism is used to monitor in real time whether a communication interruption event occurs in the industrial system, such as periodically (e.g., every second) sending application-layer survival messages. If N consecutive messages are lost (e.g., 3 times), it is determined to be an interruption. If no communication interruption event is detected in the industrial system, there is no need to match a communication reconnection strategy, and the communication status of the industrial system continues to be monitored.

[0062] Furthermore, the step of matching a communication reconnection strategy based on the communication interruption event, and the industrial system performing fault recovery based on the communication reconnection strategy, includes: performing event type analysis on the communication interruption event to obtain event type information; constructing a communication reconnection strategy library, determining a communication reconnection strategy based on the event type information using the communication reconnection strategy library; determining an operation unit and execution engine based on the communication reconnection strategy, and the industrial system performing fault recovery based on the operation unit and execution engine using the communication reconnection strategy.

[0063] Specifically, if a communication interruption event is detected in the industrial system, an event type analysis is performed on the communication interruption event to obtain event type information. Monitoring data of the industrial system is obtained, such as hardware link status (read directly from the operating system network interface, value 1 indicates link is connected, 0 indicates link is disconnected); heartbeat / polling timeout event (application layer or middleware reports no response from the peer device). The monitoring data is input into a preset diagnostic decision tree, which outputs the event type of the communication interruption event based on the monitoring data. The preset diagnostic decision tree can be a random forest model.

[0064] A communication reconnection policy library is constructed. The policy structure of this library is a tuple of {Conditions, Actions, Metadata} for each policy. Conditions are set based on matching rules such as event type, device role, and interruption duration. Actions define a series of atomic operations. Metadata defines policy priority, timeout, and whether preemption is possible. Based on the event type information, the communication reconnection policy library is used to determine the communication reconnection policy. The event type information is matched against the communication reconnection policy library, and the policy with the highest priority and a perfect match is selected. For example, when a communication interruption is detected, a reconnection operation will first be attempted under the current protocol. The system will set a maximum number of retries to prevent infinite retries. If the current protocol reconnection fails, the system will automatically switch to other available protocols according to a preset priority order. During the switching process, the system will skip the currently failed protocol and try to establish a connection with other available protocols in turn.

[0065] Based on the communication reconnection strategy, operation units and execution engines are determined. Operation units are operation functions corresponding to fault recovery, such as `action_switch_interface()`. The execution engine is a state machine responsible for sequentially and atomically calling the operation units and handling timeouts and failure rollbacks. The industrial system utilizes the operation units and execution engine for fault recovery based on the communication reconnection strategy. The industrial system's execution engine drives the operation units to complete the recovery process of the communication reconnection strategy. Target data of the fault recovery process, such as recovery step timestamps, is recorded.

[0066] Log recording module 25: used to generate target logs based on the target data, communication protocol switching analysis results, communication interruption events and communication reconnection strategies, and store the target logs in the corresponding nodes.

[0067] In a specific implementation of this invention, the step of generating a target log based on the target data, communication protocol switching analysis results, communication interruption events, and communication reconnection strategies, and storing the target log in the corresponding node, includes: integrating log content based on the target data, communication protocol switching analysis results, communication interruption events, and communication reconnection strategies to obtain the target log; performing encryption strategy analysis on the target log to obtain the target encryption strategy; and storing the target log in the corresponding node based on the target encryption strategy.

[0068] Specifically, based on the target data, communication protocol switching analysis results, communication interruption events, and communication reconnection strategies, log content is integrated, consolidating the scattered target data, communication protocol switching analysis results, communication interruption events, and communication reconnection strategies into a single log event. The target log is obtained by associating all relevant log entries during an interruption or switching process using a unified session_id or correlation_id function.

[0069] The target logs are analyzed for encryption strategies to obtain the target encryption strategy. The sensitivity level of the target logs is identified, and the encryption algorithm for the target logs is determined based on the sensitivity level; this is the target encryption strategy. Based on the target encryption strategy, the target logs are stored in the corresponding nodes. For storage on local or edge nodes, AES-256 symmetric encryption can be used. For uploads to the cloud, asymmetric encryption (such as using the cloud service's public key encryption) can be used. This comprehensive logging mechanism provides complete data support for system maintenance and fault diagnosis.

[0070] In this embodiment of the invention, a hardware detection program analyzes the protocol types of available communication interfaces to obtain protocol type information. Based on this information, a protocol priority list is constructed, and a network communication connection for the industrial system is established. This ensures the system can quickly establish the optimal communication connection. After establishing the network communication connection, communication quality analysis is performed to obtain communication quality information. Based on this information, communication protocol switching analysis is conducted to optimize overall network performance and ensure the service quality of critical services. After establishing the network communication connection, the system monitors in real time for communication interruption events. If an interruption event is detected, a communication reconnection strategy is matched based on the event. The industrial system then performs fault recovery based on this strategy. This three-layer protection mechanism—a protocol priority list, dynamic protocol switching, and intelligent interruption recovery—provides multiple, heterogeneous communication backups for critical control loops and data transmission, significantly enhancing the system's survivability and resilience in complex and harsh industrial environments.
