Description

Technical Field

[0001] This invention belongs to the field of communication technology, specifically relating to an adaptive connector communication system based on industrial Ethernet. Background Technology

[0002] Industrial Ethernet, as a core communication infrastructure for modern industrial automation and intelligent manufacturing, is widely used in scenarios such as device interconnection, data acquisition, and real-time control. With its advantages of high bandwidth, low latency, and strong compatibility with IT systems, it has become the mainstream technology for industrial communication networks. In this system, connectors, as key components of the physical layer, bear the important functions of stable and reliable electrical connections and signal transmission between devices, and their performance directly affects the robustness and adaptability of the entire communication system.

[0003] Adaptive connector communication technology aims to dynamically adjust connection parameters based on network load, environmental interference, or device status to maintain communication quality. This technology typically involves real-time sensing of link status, dynamic negotiation of protocol parameters, and intelligent matching of physical interfaces, thereby enabling seamless and efficient device access and data exchange in complex industrial environments.

[0004] Existing industrial Ethernet connectors often employ fixed configurations, lacking the ability to proactively respond to changes in the communication environment. When faced with conditions such as increased electromagnetic interference, cable aging, or frequent device plugging and unplugging, traditional connectors cannot dynamically optimize impedance matching, signal equalization, or handshake protocols, easily leading to increased communication error rates or even link interruptions. Furthermore, differences in protocol compatibility between devices from different manufacturers further limit the connector's versatility and adaptability, making it difficult to maintain stable communication when integrating heterogeneous devices or dynamically adjusting network topology. Therefore, in industrial scenarios with high reliability requirements, there is an urgent need for an adaptive connector communication system capable of environmental awareness, parameter self-adjustment, and protocol compatibility. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive connector communication system based on industrial Ethernet to solve the technical problems in current industrial field communication, such as communication interruption, high link reconstruction delay, and poor data transmission reliability caused by factors such as incompatible connector physical interfaces, rigid link parameter configuration, and dynamic changes in environmental interference.

[0006] The technical solution of this invention is an adaptive connector communication system based on industrial Ethernet, comprising an adaptive physical interface module, a link status sensing module, a protocol stack dynamic reconfiguration module, an environmental interference compensation module, and a central coordination controller. The adaptive physical interface module is used to automatically identify and electrically adapt various industrial Ethernet standard interfaces at the physical layer. The link status sensing module is used to collect link bit error rate, signal jitter, transmission delay, and connection stability indicators in real time. The protocol stack dynamic reconfiguration module is used to dynamically adjust the protocol parameters of the data link layer and network layer based on the output of the link status sensing module. The environmental interference compensation module is used to monitor electromagnetic interference intensity, temperature fluctuations, and vibration frequency, and generate corresponding compensation signals. The central coordination controller is used to receive comprehensive status information from the link status sensing module and the environmental interference compensation module, and issue reconfiguration commands and adaptation strategies to the protocol stack dynamic reconfiguration module and the adaptive physical interface module.

[0007] Furthermore, the adaptive physical interface module includes a multi-standard interface detection unit, a reconfigurable electrical matching network, and a high-speed signal switching matrix. The multi-standard interface detection unit is used to detect the pin definitions, power supply voltage levels, and communication rate identifiers of the connector at the moment of insertion. The reconfigurable electrical matching network automatically configures impedance matching circuits, common-mode rejection circuits, and power isolation circuits based on the detection results. The high-speed signal switching matrix is ​​used to route physical signals to the corresponding standard signal processing channels to ensure that signal integrity meets the requirements of the IEEE 802.3 series of industrial Ethernet specifications.

[0008] Furthermore, the link status awareness module includes an embedded bit error detector, a clock jitter analysis unit, a round-trip delay measurement unit, and a connection stability evaluator. The embedded bit error detector calculates the bit error rate in real time through cyclic redundancy check and forward error correction code residual analysis. The clock jitter analysis unit calculates the peak-to-peak jitter and time-domain jitter distribution based on the phase error sequence of the receiver clock recovery circuit. The round-trip delay measurement unit measures the end-to-end transmission delay using a timestamp exchange mechanism. The connection stability evaluator generates a link health score by combining the above indicators, and triggers a link reconstruction request when the score is lower than a preset threshold.

[0009] Furthermore, the protocol stack dynamic reconfiguration module includes a programmable MAC controller, a dynamic IP configuration unit, and a QoS policy engine; the programmable MAC controller supports switching between full-duplex and half-duplex modes, adjusting frame interval time, and retransmission count based on link health scores; the dynamic IP configuration unit automatically activates the backup IP address pool and performs fast address resolution after detecting a link interruption; the QoS policy engine dynamically allocates bandwidth resources based on application layer service priority tags, and prioritizes ensuring the transmission latency and packet loss rate of high-priority data streams when link quality deteriorates.

[0010] Furthermore, the environmental interference compensation module includes a broadband electromagnetic field sensor, a temperature gradient detection array, a triaxial vibration sensor, and an interference feature extraction unit. The broadband electromagnetic field sensor covers the 30MHz to 6GHz frequency band and is used to monitor the intensity of radio frequency interference in real time. The temperature gradient detection array is distributed along the connector shell and is used to capture the influence of local thermal deformation on contact resistance. The triaxial vibration sensor detects the frequency and amplitude of mechanical vibration. The interference feature extraction unit fuses the above raw data into an interference feature vector and inputs it into a pre-trained interference-error mapping model, outputting the corresponding signal compensation parameters.

[0011] Furthermore, the central coordination controller incorporates a state fusion engine and a policy decision tree. The state fusion engine weights and fuses the link health score with the interference feature vector to generate a comprehensive communication quality index. The policy decision tree matches a preset reconstruction policy set based on the comprehensive communication quality index. The policy set includes interface standard switching policy, protocol parameter adjustment policy, and anti-interference compensation policy. When the comprehensive communication quality index is lower than a first threshold, only protocol parameter adjustment is initiated. When it is lower than a second threshold, both interface standard switching and anti-interference compensation are initiated. When it is lower than a third threshold, a complete link reconstruction process is triggered.

[0012] Furthermore, the system operates under a dual-redundancy architecture, including a main communication channel and a hot backup channel; the main communication channel and the hot backup channel share the same adaptive physical interface module, but each is equipped with an independent link status awareness module and a protocol stack dynamic reconstruction module; the central coordination controller seamlessly switches to the hot backup channel after the overall communication quality index of the main channel has been continuously lower than the threshold for more than a preset time window, and performs self-testing and parameter recalibration on the main channel in the background.

[0013] Furthermore, the adaptive physical interface module supports automatic identification and switching of four mainstream industrial Ethernet standards: Profinet, EtherNet / IP, Modbus TCP, and CC-Link IE, with a switching delay of no more than 50 milliseconds; the protocol stack dynamic reconstruction module supports dynamic adjustment of the MAC layer retransmission count between 1 and 8 times, and dynamic adjustment of the frame interval between 96 bits and 512 bits; the interference-error mapping model of the environmental interference compensation module adopts an online learning mechanism, updating the model parameters every 24 hours based on historical error data.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows: This invention fundamentally solves the problem of unreliable communication in industrial settings caused by heterogeneous interfaces, fragile links, and harsh environments by constructing a system architecture that integrates physical interface adaptation, real-time link status perception, dynamic protocol stack reconfiguration, and proactive environmental interference compensation. The adaptive physical interface module can automatically identify and electrically adapt multiple standard interfaces within milliseconds, eliminating the risks of manual configuration errors and interface incompatibility. The closed-loop linkage mechanism between the link status perception module and the dynamic protocol stack reconfiguration module enables the system to proactively adjust protocol parameters in the early stages of link quality degradation, avoiding communication interruptions and significantly improving link availability. The environmental interference compensation module minimizes the impact of external interference on signal integrity through multi-source sensing and model-driven compensation strategies, ensuring stable communication even under strong electromagnetic, high-temperature, or high-vibration conditions. Dual redundant channels and a seamless switching mechanism further guarantee the continuous transmission of critical control commands, meeting the stringent requirements of industrial automation for high reliability and low-latency communication. The overall system does not rely on external configuration tools or manual intervention, possessing a high degree of autonomy and environmental adaptability, providing a solid and reliable communication foundation for intelligent manufacturing, flexible production lines, and remote operation and maintenance scenarios.

Detailed Implementation

[0016] Example 1 Please refer to Figure 1 and Figure 2 This invention provides an adaptive connector communication system based on industrial Ethernet, aiming to solve the technical problems of communication interruption, high link reconstruction delay, and poor data transmission reliability caused by factors such as incompatible connector physical interfaces, rigid link parameter configuration, and dynamic changes in environmental interference in current industrial field communication. This invention fundamentally improves the reliability, stability, and environmental adaptability of industrial Ethernet communication by constructing a system architecture that integrates physical interface adaptation, real-time link status perception, dynamic protocol stack reconstruction, and active compensation for environmental interference.

[0017] This industrial Ethernet-based adaptive connector communication system, as an integrated solution, aims to ensure continuous, efficient, and reliable data exchange for industrial control, data acquisition, and monitoring systems in complex and ever-changing industrial environments. The system operates within a network environment comprised of intelligent terminals distributed across various industrial devices and one or more centralized industrial switches. The system's technical flow begins with the insertion and interface identification of physical connectors, followed by real-time monitoring of the communication link performance and dynamic adjustment of protocol parameters based on the monitoring results. Simultaneously, it continuously senses and compensates for external environmental interference. All these processes are macroscopically scheduled and commanded by a central coordinating controller.

[0018] The adaptive physical interface module aims to automatically identify and electrically adapt to various industrial Ethernet standard interfaces at the physical layer. This module is fundamental to ensuring the system's compatibility with heterogeneous industrial Ethernet physical connections. When an industrial Ethernet connector is inserted into the system port, this module can autonomously detect and identify the type of industrial Ethernet protocol it follows, such as Profinet, EtherNet / IP, Modbus TCP, or CC-Link IE, and adjust the corresponding electrical parameters to ensure a stable physical connection is established.

[0019] The adaptive physical interface module includes a multi-standard interface detection unit, a reconfigurable electrical matching network, and a high-speed signal switching matrix.

[0020] The multi-standard interface detection unit is used to detect the pin definitions, supply voltage levels, and communication rate identifiers of a connector at the moment of insertion. This unit is the initiator and information collector of the entire adaptive process. When a physical connection establishment attempt is detected, the multi-standard interface detection unit immediately initiates a series of electrical scans and signal probing procedures. First, the unit quickly identifies the electrical characteristics and logical arrangement of the connector pins, such as the layout of data pairs, control lines, and power lines, using low-voltage differential signal scanning technology. Second, the unit applies a weak probe voltage and measures its response to determine the supply voltage level and polarity, such as 5 volts, 12 volts, or 24 volts industrial DC power supply standards. Simultaneously, the unit attempts to perform low-speed handshake communication, parsing the communication rate identifiers that may be contained in the standard protocol header, such as 10 megabits per second, 100 megabits per second, or 1000 megabits per second. All detected information, including pin topology, voltage information, and rate identifiers, is encapsulated into a standardized interface metadata packet and sent to the subsequent reconfigurable electrical matching network and high-speed signal switching matrix as the basis for their configuration. The detection process is typically completed within milliseconds, ensuring rapid response and connection establishment.

[0021] The reconfigurable electrical matching network automatically configures impedance matching circuits, common-mode rejection circuits, and power isolation circuits based on the detection results of multi-standard interface detection units. This network is crucial for ensuring signal integrity and electromagnetic compatibility. Upon receiving interface metadata, the reconfigurable electrical matching network parses the data using its integrated high-speed digital signal processor and determines the electrical parameters applicable to the current connector interface based on a preset configuration lookup table. For example, if a Profinet interface is detected, the network automatically adjusts its internal resistor, capacitor, and inductor arrays to achieve specific impedance matching required by the Profinet protocol, such as a 100-ohm differential impedance. The common-mode rejection circuit effectively filters out common-mode noise by adjusting the common-mode inductor or employing active common-mode rejection technology based on the detected electromagnetic interference characteristics. The power isolation circuit selects an appropriate isolation transformer or optocoupler based on the supply voltage level to achieve electrical isolation and prevent interference from ground loop currents and voltage transients to communication signals. All these configurations are dynamically adjusted at the nanosecond level using digital control analog technology, ensuring accurate and real-time adaptation.

[0022] High-speed signal switching matrices are used to route physical signals to signal processing channels of corresponding standards, ensuring signal integrity meets the requirements of the IEEE 802.3 series of industrial Ethernet specifications. As a data path manager at the physical layer, the core function of the high-speed signal switching matrix is ​​to accurately guide the original electrical signals to pre-set signal processing paths optimized for different protocol standards within the system, based on the adapted interface standard. For example, if an EtherNet / IP interface supporting Gigabit Ethernet is detected, the matrix will route the signal to a differential pair processing channel with higher bandwidth and lower noise, and enable pre-emphasis and equalization techniques for gigabit transmission to compensate for signal attenuation and distortion along the transmission path. The matrix internally employs low insertion loss, high isolation semiconductor switch arrays or MEMS switches, configured via control commands sent from a central coordinating controller. To meet the stringent signal integrity requirements of the IEEE 802.3 series standards, such as return loss, insertion loss, and crosstalk performance, the matrix is ​​designed with high-speed signal transmission characteristics in mind, employing layout and routing strategies such as controlled impedance routing, minimizing trace length differences, and avoiding sharp-angle bends. The switching delay is strictly controlled within an extremely low range to meet industrial real-time requirements, with a switching delay of no more than 50 milliseconds.

[0023] The link status awareness module aims to collect real-time data on link error rate, signal jitter, transmission delay, and connection stability indicators. This module acts as the system's eyes, proactively adapting to link changes and providing decision-making support for subsequent dynamic protocol stack reconfiguration and the central coordination controller. The link status awareness module continuously monitors various key performance parameters of the communication link, quantifying the link's health status through a series of embedded measurement and analysis units, and using this data as core data for link quality assessment.

[0024] The link status awareness module includes an embedded bit error detector, a clock jitter analysis unit, a round-trip delay measurement unit, and a connection stability evaluator.

[0025] The embedded bit error rate detector calculates the bit error rate in real time through cyclic redundancy check (CRC) and forward error correction (FEC) residual analysis. This detector serves as the first line of defense for link data integrity checks. When data flows through a communication link, each data frame is typically appended with a CRC code. The embedded bit error rate detector performs CRC calculations on the incoming data frames at the receiving end and compares the result with the received check code. Any mismatch indicates the presence of a bit error. To more precisely assess the bit error situation, the detector also analyzes the decoding residuals of the FEC. The FEC adds redundant information at the sending end, which the receiving end can use to correct a certain number of errors. However, when the FEC cannot completely correct all errors, residuals are generated. Analyzing these residuals allows for a more accurate quantification of the number and distribution of uncorrected bit errors, thus enabling real-time calculation of the precise bit error rate or frame error rate. The bit error rate data is statistically analyzed using a sliding window average, and a threshold is set. When the bit error rate exceeds a certain level, an alarm or further link diagnostics are triggered.

[0026] The clock jitter analysis unit calculates peak-to-peak jitter and time-domain jitter distribution based on the phase error sequence of the receiver's clock recovery circuit. In high-speed serial communication, clock jitter is a critical factor affecting signal integrity. The clock jitter analysis unit monitors the output of the receiver's built-in clock recovery circuit to obtain the error sequence between the received clock and the ideal clock phase. This error sequence reflects the instantaneous deviation of the received clock relative to the transmitted clock. By statistically analyzing this phase error sequence, the unit can calculate the peak-to-peak jitter, i.e., the maximum deviation range of the phase error, and the time-domain jitter distribution, such as root-mean-square jitter. These jitter parameters directly reflect the stability of the link transmission and the ambiguity of signal edges, thus affecting the reliability of data decoding. The analysis results are then subjected to real-time spectrum analysis by an internal digital signal processor to identify the frequency components of the jitter, providing guidance for subsequent compensation mechanisms.

[0027] The round-trip delay measurement unit (RTD) uses a timestamp exchange mechanism to measure end-to-end transmission delay. Transmission delay is a key indicator for measuring the real-time performance of communication. The RTD measurement unit measures delay by embedding a precise timestamp in the transmitted data packet, extracting the timestamp at the receiving end, and immediately sending back a response packet containing both the received and transmitted timestamps. Upon receiving the response packet, the sending end uses four timestamps (transmission time, reception time, response transmission time, and response reception time) and a specialized algorithm to calculate the precise one-way and round-trip delays. To ensure timestamp accuracy, the system relies on a high-precision hardware clock synchronization protocol, such as IEEE 1588 Precision Time Protocol or Network Time Protocol, to ensure that the time bases of the sending and receiving ends are consistent. The measurement results are statistically presented as average delay and delay jitter, providing data support for priority scheduling by the QoS policy engine.

[0028] The connection stability evaluator generates a link health score by combining the above indicators. When the score falls below a preset threshold, a link reconfiguration request is triggered. The connection stability evaluator is the decision-making core of the link status awareness module. It receives all real-time data from the embedded bit error rate detector, clock jitter analysis unit, and round-trip delay measurement unit, including bit error rate, peak-to-peak jitter, root mean square jitter, average transmission delay, and latency jitter. The evaluator incorporates a multivariate weighted fusion algorithm, such as an evaluation model based on fuzzy logic or machine learning, to integrate these heterogeneous indicators into a unified link health score. The score is a value from 0 to 100, with 100 representing the best link status. The evaluation model assigns different weights to different indicators based on historical data and expert knowledge; for example, in specific industrial applications, bit error rate may have a higher weight than latency jitter. When the calculated link health score consistently falls below a preset threshold, such as 70, the evaluator determines that the link quality has significantly deteriorated and immediately sends a link reconfiguration request to the central coordination controller, initiating the system's adaptive adjustment process.

[0029] The protocol stack dynamic reconfiguration module aims to dynamically adjust the protocol parameters of the data link layer and network layer based on the output of the link state awareness module. This module is the core execution mechanism for the system to proactively intervene in link degradation. When the link state awareness module detects a decline in link performance, the protocol stack dynamic reconfiguration module adjusts key parameters in the communication protocol stack according to instructions issued by the central coordination controller to optimize data transmission efficiency and reliability.

[0030] The protocol stack dynamic reconfiguration module includes a programmable MAC controller, a dynamic IP configuration unit, and a QoS policy engine.

[0031] The programmable MAC controller supports switching between full-duplex and half-duplex modes, adjusting frame intervals, and adjusting retransmission counts based on link health scores. The programmable MAC controller is the executor of data link layer parameter adjustments. In the early stages of link quality degradation, such as when the link health score drops from 95 to 80, the central coordinating controller may instruct the MAC controller to adjust parameters to enhance link robustness. For example, when the link experiences slight jitter but the bit error rate remains within acceptable limits, the controller may increase the retransmission count from the default 2 to 4 to improve the probability of successful data frame transmission. If link quality deteriorates further, such as due to severe signal attenuation caused by environmental interference, the central coordinating controller may determine that the current full-duplex mode is insufficient to maintain stable communication. In this case, the programmable MAC controller can switch to half-duplex mode to improve channel utilization by avoiding collisions. The frame interval, i.e., the time interval between two consecutive data frames, can also be dynamically adjusted between 96 bits and 512 bits. When the link is congested or the bit error rate is high, appropriately increasing the frame interval can reduce collisions and retransmissions, thereby improving overall throughput. All these parameter adjustments are achieved through programming the internal registers of the MAC controller, ensuring fine-grained and real-time control.

[0032] Upon detecting a link interruption, the Dynamic IP Configuration Unit (DLL) automatically activates the backup IP address pool and performs fast address resolution. The DLL ensures network layer robustness. When the link status awareness module reports a complete link interruption, such as when the link health score falls below 20, the system determines that the current network path has failed. At this point, the central coordinating controller instructs the DLL to initiate a fast link recovery process. The DLL immediately selects an available IP address from the pre-set backup IP address pool and assigns it to the current device. Next, the DLL executes a fast address resolution protocol, such as by broadcasting ARP requests, to update the address resolution protocol caches of other devices in the network, ensuring that the new IP address can be quickly recognized by the network. This process coordinates with the central coordinating controller's instruction to the adaptive physical interface module to switch to the backup physical channel, enabling devices to quickly switch to redundant network paths and minimizing communication interruption time. The management of the IP address pool and the priority of address resolution are optimized based on the industrial site's topology and real-time requirements.

[0033] The QoS policy engine dynamically allocates bandwidth resources based on application-layer service priority tags, prioritizing the transmission latency and packet loss rate of high-priority data flows when link quality deteriorates. The QoS policy engine is the core component ensuring the continuity of critical business data transmission. In industrial Ethernet, different service flows have different priorities; for example, real-time control commands have the highest priority, while data log transmissions have lower priority. The QoS policy engine classifies data flows by identifying application-layer service priority tags in data packets, such as based on Differentiated Services Code Points or VLAN priority tags. When link quality is normal, the engine allocates bandwidth using weighted fair queuing or round-robin scheduling algorithms. However, when link quality deteriorates, such as due to limited bandwidth resources or increased bit error rate, the central coordinating controller instructs the QoS policy engine to activate the priority protection mechanism. The engine immediately adjusts the scheduling algorithm, such as switching to strict priority queuing, to ensure that high-priority data flows (such as motion control and safety interlock signals) have priority transmission opportunities, while reducing the transmission rate of low-priority data flows or allowing for higher packet loss rates. By dynamically adjusting queue length, bandwidth limits, and scheduling weights, the QoS policy engine can maximize the protection of transmission latency and packet loss rate of critical business flows with limited resources, thus maintaining the normal operation of core functions.

[0034] The environmental interference compensation module aims to monitor electromagnetic interference intensity, temperature fluctuations, and vibration frequency, and generate corresponding compensation signals. This module is crucial for the system's proactive defense against external non-electrical interference. Harsh industrial environments are common sources of interference, including electromagnetic radiation, drastic temperature changes, and mechanical vibration. These interferences can lead to signal attenuation, increased crosstalk, and equipment performance drift. The environmental interference compensation module uses multi-dimensional sensing technology to detect these interferences in real time and generate compensation parameters to mitigate their impact on communication links.

[0035] The environmental interference compensation module includes a broadband electromagnetic field sensor, a temperature gradient detection array, a triaxial vibration sensor, and an interference feature extraction unit.

[0036] A wideband electromagnetic field sensor, covering the 30 MHz to 6 GHz frequency band, is used for real-time monitoring of radio frequency interference intensity. This sensor is the core component for detecting the electromagnetic environment. It integrates a set of miniature antenna arrays covering a wide frequency band with a high-precision analog-to-digital converter, enabling it to capture electromagnetic waves from the surrounding environment in real time. The sensor performs spectral analysis on the received electromagnetic wave signals, converting the time-domain signal into a frequency-domain energy distribution map using a Fast Fourier Transform. The system can identify interference sources within specific frequency ranges, such as harmonics from switching power supplies, radiation from wireless communication devices, or transient electromagnetic pulses generated by motor startup. The sensor transmits real-time electromagnetic interference intensity data, such as the power spectral density per unit frequency band, to the interference feature extraction unit. This data provides a quantitative basis for the system to assess electromagnetic compatibility risks and adjust communication strategies.

[0037] A temperature gradient detection array is distributed along the connector shell to capture the impact of localized thermal deformation on contact resistance. When connectors operate for extended periods in high-temperature industrial environments or are exposed to external heat sources, their internal materials undergo thermal expansion and contraction, leading to changes in contact resistance and consequently affecting signal transmission quality. The temperature gradient detection array consists of multiple miniature thermistors or thermocouples, uniformly distributed along the surface of the connector shell. The array accurately measures the real-time temperature of different parts of the connector and calculates the temperature gradient. Through analysis of historical data and material thermodynamic models, the system establishes a mapping relationship between temperature gradient and contact resistance changes. When a significant temperature gradient or an absolute temperature exceeding a preset value is detected, the array sends relevant data to an interference feature extraction unit to assess the potential impact of thermal deformation on link performance. This data is crucial for predicting connector aging and for preventative maintenance.

[0038] A triaxial vibration sensor detects the frequency and amplitude of mechanical vibrations. Industrial equipment often experiences mechanical vibrations during operation; continuous vibration can lead to loose connectors or even momentary signal interruptions. The triaxial vibration sensor integrates a microelectromechanical system (MEMS) accelerometer, capable of simultaneously measuring vibration acceleration in the X, Y, and Z directions. The raw data output by the sensor is filtered and processed using Fourier transform to obtain the vibration frequency spectrum and amplitude. The system focuses on resonance phenomena within specific frequency ranges, such as vibrations matching the natural frequencies of the machine equipment, as well as short-duration, high-amplitude impact vibrations. This vibration data is transmitted to an interference feature extraction unit to assess the impact of mechanical stress on connection stability and signal integrity. Real-time monitoring of vibration data helps the system provide early warnings and compensation before vibration causes actual bit errors.

[0039] The interference feature extraction unit fuses the raw data into an interference feature vector, which is then input into a pre-trained interference-bit error rate mapping model, outputting the corresponding signal compensation parameters. The interference feature extraction unit is the intelligent core of environmental interference perception and compensation. It receives raw data streams from a broadband electromagnetic field sensor, a temperature gradient detection array, and a triaxial vibration sensor, and performs preprocessing, feature engineering, and fusion on these data. Preprocessing includes noise cancellation, data normalization, and time synchronization. Feature engineering extracts meaningful features from the raw data; for example, it extracts the dominant interference frequency and power from the electromagnetic field data, the maximum temperature difference and rate of change from the temperature gradient, and the resonant frequency and peak amplitude from the vibration data. These features are combined into a multi-dimensional interference feature vector. This vector is then input into a pre-trained interference-bit error rate mapping model. This model is a machine learning model, such as one based on a deep neural network or support vector machine, trained on a large amount of historical data (including sensor readings under various interference conditions and corresponding actual bit error rates) to learn the nonlinear relationship between interference features and bit error rate. The model outputs a set of signal compensation parameters, such as channel equalizer parameters, adaptive filter coefficients, or power adjustment suggestions. The model employs an online learning mechanism, updating its parameters every 24 hours based on new historical bit error rate data to ensure it adapts to the dynamic changes in the industrial environment.

[0040] The central coordination controller is designed to receive comprehensive status information from the link state awareness module and the environmental interference compensation module, and to issue reconstruction commands and adaptation strategies to the protocol stack dynamic reconstruction module and the adaptive physical interface module. The central coordination controller is the brain of the entire adaptive communication system, responsible for global state assessment, decision-making, and command issuance. It is a high-performance real-time embedded processor with a built-in real-time operating system, capable of efficiently processing data streams from various modules and performing complex calculations.

[0041] The central coordination controller has a built-in state fusion engine and policy decision tree.

[0042] The state fusion engine weighted and fused the link health score and interference feature vector to generate a comprehensive communication quality index. This engine forms the basis for the central coordinating controller's global evaluation. It receives the link health score generated by the link state awareness module, a single numerical value quantifying the link's intrinsic performance. Simultaneously, the engine receives interference feature vectors generated by the interference feature extraction unit, which contain multi-dimensional external environmental information such as electromagnetic interference, temperature changes, and mechanical vibration. The state fusion engine employs a fusion strategy based on expert system rules and an adaptive weighting algorithm to weight and integrate these two different sources and types of data. For example, in a high-vibration environment, vibration features are given higher weight in the fusion algorithm. The fusion result is a comprehensive communication quality index, typically a value between 0 and 100, comprehensively reflecting the overall availability of the current communication link and the external challenges it faces. This index is the sole input for subsequent policy decision trees.

[0043] The strategy decision tree is based on a comprehensive communication quality index matched with a preset set of reconstruction strategies. These strategies include interface standard switching strategies, protocol parameter adjustment strategies, and anti-interference compensation strategies. The strategy decision tree is the core of the central coordination controller's decision-making process. After the state fusion engine generates the comprehensive communication quality index, this index is input into the preset strategy decision tree. Nodes in the decision tree represent different conditional judgments, branches represent different decision paths, and leaf nodes correspond to specific reconstruction strategies. The rules of the strategy decision tree are based on encoding knowledge from industrial communication experts and machine learning analysis of historical fault patterns. The decision tree has a hierarchical structure to achieve a progressive response. When the comprehensive communication quality index falls below a first threshold, such as 80 points, it indicates that the link quality is beginning to decline. At this point, the decision tree matches the protocol parameter adjustment strategy, instructing the protocol stack dynamic reconstruction module to only fine-tune the MAC layer retransmission count or frame interval. When the overall communication quality index falls below the second threshold, for example, 60 points, it indicates a significant degradation in link quality. At this point, the decision tree will match a more aggressive strategy, instructing the adaptive physical interface module to initiate an interface standard switch, such as downgrading from Gigabit Ethernet to 100Mbps Ethernet to improve signal robustness. Simultaneously, it will instruct the environmental interference compensation module to initiate interference compensation, such as adjusting channel equalizer parameters. When the overall communication quality index falls below the third threshold, for example, 40 points, it indicates that the link is in a critical failure state. At this point, the decision tree will match the most severe strategy, triggering a complete link reconstruction process, which may involve renegotiating the physical interface and activating a backup channel. The strategy set is a predefined collection of various adjustment actions, ensuring that the system can respond accurately and hierarchically according to different levels of quality degradation.

[0044] This system operates under a dual-redundancy architecture, comprising a primary communication channel and a hot backup channel. The primary and hot backup channels share the same adaptive physical interface module, but each is equipped with an independent link-state awareness module and a protocol stack dynamic reconfiguration module. This dual-redundancy architecture is the core design element for achieving high availability and high reliability. The primary communication channel handles daily data transmission tasks, and its performance metrics are monitored and adjusted in real-time by its independent link-state awareness module and protocol stack dynamic reconfiguration module. The hot backup channel serves as a backup to the primary channel and is also equipped with an independent link-state awareness module and protocol stack dynamic reconfiguration module. This means that the hot backup channel can independently monitor its own link status and adaptively adjust protocol parameters, ensuring it remains in a "hot standby" state, ready for immediate use. Both channels share the same adaptive physical interface module because the physical interface module is the sole entry point for the system's physical connection to the outside world, and its adaptive capability is essential for the normal operation of either channel.

[0045] When the overall communication quality index of the main channel remains below a threshold for more than a preset time window, the central coordination controller seamlessly switches to the hot backup channel and performs self-checks and parameter recalibrations on the main channel in the background. This is a key mechanism for fault recovery in the dual-redundancy architecture. The central coordination controller continuously monitors the overall communication quality index of the main communication channel. When this index remains below a preset switching threshold, such as 50 points, and this low-quality state lasts for more than a preset time window, such as 200 milliseconds, the controller determines that the main channel has suffered a serious fault and cannot be recovered in the short term. At this time, the central coordination controller immediately triggers a seamless switching process. Seamless switching means switching the data path from the main channel to the hot backup channel while minimizing or eliminating interruptions to application layer data flow. This is typically achieved by quickly updating the network routing table, MAC address table, and maintaining session state at the application layer. After the switch is complete, the hot backup channel takes over the data transmission tasks. Simultaneously, the central coordination controller performs a detailed self-check and parameter recalibration process on the faulty main channel in the background. The self-check may include diagnostics of the physical interface module, sensor calibration of the link state awareness module, and software reloading of the protocol stack dynamic reconstruction module. Parameter recalibration attempts to restore the protocol parameters of the main channel to their optimal state so that it can be put back into use after the repair is completed, or used as a backup channel for future hot backup.

[0046] This system supports automatic identification and switching of four mainstream industrial Ethernet standards: Profinet, EtherNet / IP, Modbus TCP, and CC-Link IE, with a switching latency of no more than 50 milliseconds. The system dynamically adjusts the number of MAC layer retransmissions between 1 and 8, and the frame interval between 96 and 512 bits. The interference-error mapping model of the environmental interference compensation module adopts an online learning mechanism, updating the model parameters every 24 hours based on historical error data.

[0047] In summary, the adaptive connector communication system based on industrial Ethernet proposed in this invention fundamentally solves the reliability and stability challenges of industrial field communication through the tight integration of adaptive physical interfaces, real-time link status sensing, dynamic protocol stack reconfiguration, and proactive environmental interference compensation. The system's adaptive physical interface module automatically identifies and electrically adapts multiple standard interfaces at the millisecond level, effectively avoiding the risks of manual configuration errors and interface incompatibility. The closed-loop linkage between the link status sensing module and the dynamic protocol stack reconfiguration module enables the system to proactively adjust communication parameters in the early stages of link quality degradation, significantly improving link availability and effectively preventing communication interruptions. The environmental interference compensation module, through multi-source sensor data and model-driven compensation strategies, minimizes the impact of external interference on signal integrity, ensuring stable communication operation under extreme industrial conditions. Dual redundant channels and a seamless switching mechanism further guarantee the continuous transmission of critical control commands, fully meeting the stringent requirements of high reliability and low latency communication in the field of industrial automation. This system possesses a high degree of autonomy and environmental adaptability, requiring no external tools or manual intervention, providing a solid and reliable communication foundation for advanced industrial scenarios such as intelligent manufacturing, flexible production lines, and remote operation and maintenance.

[0048] Example 2 The adaptive connector communication system based on industrial Ethernet proposed in this invention, building upon Embodiment 1 above, further details the internal decision-making logic and implementation mechanism of its policy decision tree. As the core intelligent component of the central coordinating controller, the policy decision tree is designed to quickly and accurately select the optimal link reconstruction strategy and anti-interference compensation strategy when faced with multi-dimensional and dynamically changing communication quality indicators. The construction and optimization of the decision tree are crucial to ensuring the system maintains communication robustness in complex industrial environments.

[0049] The construction process of the policy decision tree is as follows: First, the system collects a large amount of historical communication data, including link status awareness data, environmental interference data, and corresponding communication quality indices and system response records under different time periods and environmental conditions. Second, using this data, the decision tree model is trained offline using machine learning algorithms, such as C4.5 or CART. The goal of the training is to learn the mapping relationship between the comprehensive communication quality index and the optimal response strategy. Each internal node of the decision tree represents a judgment condition for the comprehensive communication quality index, such as "whether the comprehensive communication quality index is lower than 80", while each leaf node represents a specific set of strategies, including combinations of interface standard switching strategies, protocol parameter adjustment strategies, and anti-interference compensation strategies.

[0050] The hierarchical response mechanism of the decision tree is precisely defined. When the state fusion engine outputs the comprehensive communication quality index... Afterwards, the central coordination controller will The input is fed into the policy decision tree for evaluation. The decision-making process follows this logic: Condition 1: If ,in The first threshold is 80. At this point, the decision tree determines that the communication link is in good condition or only has slight fluctuations, and no large-scale reconstruction measures are needed. The system will maintain the current link configuration and instruct the protocol stack dynamic reconstruction module to perform routine performance optimization or fine-tuning, such as dynamically adjusting the QoS priority queue length according to real-time traffic load, but will not touch upon changes to core parameters.

[0051] Condition 2: If ,in This is the second threshold, for example, 60. At this point, the decision tree determines that the communication link quality has significantly deteriorated, possibly due to persistent interference or the link performance beginning to deteriorate. The system will then apply a moderate reconstruction strategy. The core of this strategy is to instruct the protocol stack dynamic reconstruction module to initiate comprehensive protocol parameter adjustments. This includes dynamically adjusting the MAC layer retransmission count (e.g., increasing it from 2 to 4 or 6 times), optimizing frame intervals to reduce collisions, and reallocating bandwidth resources based on service priorities. Simultaneously, if the environmental interference compensation module detects persistent moderate interference, the central coordination controller will also instruct it to initiate corresponding signal compensation measures, such as activating the channel equalizer or adjusting receiver sensitivity parameters. The goal of this stage is to proactively mitigate the problem and prevent further deterioration of communication quality.

[0052] Condition 3: If ,in The third threshold is 40. At this point, the decision tree determines that the communication link quality has severely degraded, potentially posing a risk of interruption. The system will then apply an aggressive refactoring strategy. This strategy, in addition to including all the measures of a moderate refactoring approach, will further instruct the adaptive physical interface module to initiate an interface standard switch, such as downgrading from Gigabit Ethernet to 100Mbps Ethernet, sacrificing some bandwidth for stronger signal interference resistance and longer transmission distance. This downgrading operation is typically accompanied by a decrease in communication speed, but it has significant advantages in ensuring communication continuity. Simultaneously, the environmental interference compensation module will initiate a more aggressive compensation algorithm, such as employing an adaptive noise cancellation filter, to suppress environmental interference to the greatest extent possible. The focus at this stage is to maintain basic communication capabilities as much as possible under extremely harsh conditions.

[0053] Condition 4: If At this point, the decision tree determines that the communication link is in a critical state of failure or imminent interruption. The system will match the most urgent reconstruction strategy, triggering a complete link rebuild process. This process includes the following steps: First, the central coordination controller instructs the adaptive physical interface module to attempt to renegotiate the physical layer connection, which may involve disconnecting and re-establishing the connection. Second, the dynamic IP configuration unit initiates a fast IP address update process, preparing to use a backup IP address. Most importantly, if the system is running in a dual-redundancy architecture, the central coordination controller will immediately initiate a seamless switchover to the hot backup channel. After the switchover is complete, the original faulty channel will undergo a comprehensive self-check and fault diagnosis in the background.

[0054] In this embodiment, the threshold of the strategy decision tree , and The specific values ​​were determined through analysis of extensive historical operational data from industrial sites, combined with Monte Carlo simulations and expert experience. The threshold settings considered not only the absolute value of the communication quality index but also its rate of change and trend to avoid misjudgments. For example, even... temporarily lower However, if the rate of decline is slow and there is no continued deterioration trend, the system may not immediately trigger protocol parameter adjustments, but will instead prioritize observation. This dynamic threshold strategy gives decision trees greater flexibility and accuracy.

[0055] Furthermore, the policy decision tree incorporates a built-in policy conflict resolution mechanism. In certain complex situations, different reconstruction policies may conflict with each other. For example, an anti-interference compensation policy may not meet the electrical parameter requirements after interface standard switching. In such cases, the decision tree will select a higher-priority policy to execute based on preset priority rules, or choose a comprehensive policy that can simultaneously satisfy all constraints. For instance, link integrity and real-time performance typically have the highest priority, so policies that guarantee these metrics will be prioritized.

[0056] This embodiment significantly enhances the decision-making capabilities of the central coordinating controller in complex and dynamically changing industrial communication environments through the refined design and implementation of the strategy decision tree. The hierarchical response mechanism of the decision tree ensures that the system can make progressive and appropriate responses to communication quality issues of varying degrees, avoiding overreaction or underreaction. This intelligent decision-making capability enables the entire adaptive connector communication system not only to perceive and respond to communication link degradation, but also to proactively maintain and optimize the robustness and reliability of the communication link through strategic adjustments, thereby providing continuous and stable data transmission guarantees for industrial production. This rule-based and data-driven decision-making method organically combines the experience of engineers with the advantages of machine learning, achieving a high degree of system autonomy and environmental adaptability.

[0057] Example 3 The adaptive connector communication system based on industrial Ethernet proposed in this invention, building upon the above embodiments, further elaborates on the seamless switching mechanism between the primary communication channel and the hot backup channel in a dual-redundancy architecture. Seamless switching is a core function that ensures the system can still provide continuous communication services under extreme failure conditions, and it is of paramount importance for critical industrial control systems.

[0058] The design principle of the dual-redundancy architecture is that the primary communication channel is responsible for normal business communication, while the hot backup channel continuously monitors its own status in the bypass and is ready to take over at any time. This "primary-backup" mode ensures that in the event of any failure in the primary channel, the system can quickly switch to the healthy backup channel with minimal business interruption.

[0059] The primary communication channel and the hot backup channel are each equipped with independent link status awareness modules and protocol stack dynamic reconfiguration modules. This means that during normal operation, the hot backup channel is not idle but actively running. The link status awareness module of the hot backup channel continuously monitors its own communication link quality, including bit error rate, signal jitter, and transmission delay, and generates an independent link health score. Simultaneously, the protocol stack dynamic reconfiguration module of the hot backup channel also adaptively adjusts protocol parameters according to its own link status, ensuring that its communication link is always in optimal availability. This design avoids the delay of initialization and parameter adaptation only after a primary channel failure, thus achieving true "hot backup."

[0060] The central coordination controller continuously monitors the overall communication quality index of the main communication channel. .when Continuously below the preset switching threshold (For example, 50 minutes) Exceeding the preset time window At a time (e.g., 200 milliseconds), the central coordinating controller will trigger a seamless handover process.

[0061] The detailed steps of the seamless transition process are as follows: Fault diagnosis and switchover command issuance: The central coordinating controller first confirms that the main channel has suffered a serious fault and cannot quickly self-heal. It broadcasts a switchover command to the relevant industrial Ethernet switches and terminal devices in the network. This command typically includes the target channel identifier (hot backup channel) and necessary network configuration information.

[0062] Network path redirection: MAC layer switching: The central coordinating controller instructs the industrial Ethernet switches to update the MAC address mappings that originally pointed to the primary channel devices to the MAC addresses of the hot backup channel devices. This process is completed internally by the switch and typically involves modifying Address Resolution Protocol (ARP) entries or the equivalent Layer 2 forwarding database.

[0063] IP Layer Switching: If the Dynamic IP Configuration Unit (DHCP) has pre-assigned a backup IP address to the hot standby channel before the primary channel fails, the switching command will include this backup IP address. Upon receiving the command, the network device updates its routing table and IP address resolution protocol cache, redirecting traffic destined for the failed device to the backup IP address of the hot standby channel. If virtual IP address technology is used, only the owner of the virtual IP address needs to be switched from the primary channel to the hot standby channel.

[0064] Application-layer session persistence (or rapid recovery): This is key to achieving "seamlessness." For industrial applications that support session persistence, the central coordinating controller or relevant gateway attempts to migrate the TCP or UDP session state (e.g., sequence number, acknowledgment number, connection identifier) ​​on the primary channel to a hot backup channel. If the session state migration is successful, application-layer communication will be virtually unaffected. For applications that do not support session migration, the system utilizes rapid IP switching and MAC address updates to minimize communication interruption time, enabling the application layer to re-establish connections in a very short time, thus achieving a "near-seamless" effect.

[0065] Real-time control command synchronization: For critical real-time control commands, the system employs a more advanced synchronization mechanism. During normal operation, the protocol stacks of the primary and hot backup channels may synchronize critical control states and command sequence numbers in real time. During switchover, the hot backup channel can immediately take over from the most recently synchronized state, ensuring the continuity and correctness of control commands.

[0066] Background self-check and parameter recalibration of the faulty main channel: Once the hot backup channel successfully takes over the communication task, the central coordination controller will immediately start a detailed diagnostic process for the main channel in the background.

[0067] Physical layer diagnostics: Check for damage to the adaptive physical interface module, such as whether connector pins are physically detached or cables are broken.

[0068] Link layer diagnostics: In-depth bit error rate, jitter and latency tests are performed using a dedicated link status awareness module for the main channel to identify the root cause of the fault.

[0069] Protocol stack diagnostics: Perform functional tests on the software and hardware of the main channel's protocol stack dynamic reconfiguration module, such as reloading the MAC controller firmware and testing the QoS engine function.

[0070] Parameter recalibration: Based on the diagnostic results, attempt to restore the main channel's protocol parameters to their initial or optimal state and perform testing. If the fault is transient, such as due to a brief period of strong electromagnetic interference, the main channel can be put back into use as a hot backup channel after calibration. If the fault is permanent, the system will log the fault and trigger a maintenance alarm.

[0071] This embodiment significantly enhances the robustness and high availability of the system by introducing independent operation of hot backup channels, a seamless switching mechanism, and a background fault diagnosis and recovery process. This design enables the industrial Ethernet-based adaptive connector communication system to withstand single points of failure. Even if the primary communication path suffers physical damage, severe interference, or software errors, it can switch to a backup path in a very short time (e.g., less than 100 milliseconds), thereby ensuring the continuity and safety of industrial production and effectively avoiding downtime losses and safety accidents caused by communication interruptions. Seamless switching is not merely a simple channel switching, but a complex coordination mechanism involving close cooperation at the physical layer, data link layer, network layer, and even the application layer, reflecting the system's high level of intelligence and engineering reliability.
