Description

Technical Field

[0001] The present application relates to the field of computer network communication technology, and in particular to a network real-time synchronization communication system. Background Art

[0002] In distributed real-time control systems, the topology and synchronization mechanisms of the communication network are key factors affecting system performance. Traditional technologies often use Ethernet star topology, fieldbus ring topology, or shared bus architecture. However, these solutions have significant limitations when meeting the requirements of high real-time performance and low jitter: Star networks rely on a central switch: While Ethernet-based star architectures are easy to manage, protocol parsing and data forwarding in switches can easily become performance bottlenecks. When multiple nodes communicate concurrently, the protocol overhead generated by layered packet encapsulation and unpacking significantly increases transmission latency. Furthermore, the switch's throughput limits system scalability, making it difficult to meet the microsecond-level synchronization requirements of industrial real-time control scenarios. Ring networks have inherent flaws: Ring topologies such as ProfiNet and EtherCat use a token-passing mechanism, and their transmission latency increases linearly with the number of nodes, resulting in a sharp drop in synchronization accuracy in large-scale deployments. Furthermore, ring structures struggle to support dynamic scaling, and node failures can easily paralyze the entire network. This makes them unsuitable for scenarios such as flexible manufacturing, which require online node scaling. Limited bus architecture performance: Traditional bus-based networks are constrained by shared bandwidth and arbitration mechanisms. The probability of conflict is high during multi-master communication, and retransmissions caused by data collisions further exacerbate delay uncertainty. In scenarios such as collaborative robot motion control, such random delays force the system to reserve redundant time slices, severely restricting real-time response efficiency.

[0003] Although existing technologies have partially alleviated the above problems through software protocol optimization, essential defects such as insufficient physical layer synchronization accuracy and uncontrollable protocol stack processing delays still exist. Especially in multi-node high-concurrency scenarios, the uncertainty of data arrival time causes the system to excessively sacrifice real-time performance in exchange for stability. Summary of the Invention

[0004] The purpose of this application is to provide a network real-time synchronization communication system, the core of which is to solve the communication uncertainty caused by data concurrency in distributed systems, and to achieve nanosecond-level node synchronization and deterministic data transmission through hardware synchronization and protocol layer collaborative control.

[0005] The present application provides a network real-time synchronization communication system that adopts the following technical solution: constructing a multi-layer architecture system including hardware optical synchronization and dynamic data orchestration, the system comprising: Hardware optical IO synchronization module, integrated into the physical layer interface of the node card, used to generate nanosecond-level precision synchronization pulse signals; The timing orchestration module is embedded in the switch control plane and executes the data frame scheduling strategy based on time-sensitive networking; Distributed RTDATA node architecture replaces traditional single-board computers as the basic network unit; Dynamic multicast sharing framework supports on-demand establishment of data channels between any nodes; The system achieves improved communication determinism through a three-stage deployment. In the first stage, optical IO synchronization is combined with a multicast framework. Nanosecond-precision pulse signals are used to trigger the time window alignment of each node, and key data is distributed based on the multicast tree. In the second stage, the dependence on optical IO synchronization hardware is gradually removed, the synchronization logic is solidified into the switch's timing orchestration engine, and the communication rhythm between nodes is maintained through a time-aware scheduling algorithm. In the third stage, the system transitions to a dynamic multicast system based entirely on RTDATA nodes, allowing any node to establish a data channel based on real-time needs while retaining the global clock calibration capability to suppress transmission jitter.

DETAILED DESCRIPTION

[0017] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0018] This application provides a real-time network synchronization communication system that builds a multi-layer architecture system that includes hardware optical synchronization and dynamic data orchestration. The communication system includes: Hardware optical IO synchronization module, integrated into the physical layer interface of the node card, used to generate nanosecond-level precision synchronization pulse signals; The timing orchestration module is embedded in the switch control plane and executes the data frame scheduling strategy based on time-sensitive networking; Distributed RTDATA node architecture replaces traditional single-board computers as the basic network unit; Dynamic multicast sharing framework supports on-demand establishment of data channels between any nodes; The system achieves improved communication determinism through a three-stage deployment. In the first stage, optical IO synchronization is combined with a multicast framework. Nanosecond-precision pulse signals are used to trigger the time window alignment of each node, and key data is distributed based on the multicast tree. In the second stage, the dependence on optical IO synchronization hardware is gradually removed, the synchronization logic is solidified into the switch's timing orchestration engine, and the communication rhythm between nodes is maintained through a time-aware scheduling algorithm. In the third stage, the system transitions to a dynamic multicast system based entirely on RTDATA nodes, allowing any node to establish a data channel according to real-time needs while retaining the global clock calibration capability to suppress transmission jitter.

[0019] The hardware optical IO synchronization module achieves physical layer synchronization by integrating a multi-channel optical transceiver array and anti-jitter circuit. The module deploys a wavelength-multiplexed optical signal transmission channel at the physical interface of the node card, combines phase-locked loop and delay locking technology to generate stable synchronization pulses, and has a built-in signal integrity detection unit. When the optical link is attenuated or has bit errors, it automatically switches to a redundant path. The synchronization pulse signal is transmitted to each RTDATA node through a dedicated clock distribution network, driving the local timing unit to maintain microsecond alignment with the global reference clock, providing a reference timeline for data concurrency control. Further, Multi-channel optical transceiver array: supports 8-wavelength multiplexing and a single-channel rate of 10Gbps; Anti-jitter circuit design: A hybrid architecture of phase-locked loop (PLL) and delay-locked loop (DLL) suppresses synchronization pulse jitter within ±2ns; Fault self-healing mechanism: Automatically switch to redundant path when the optical link bit error rate exceeds 1e-12.

[0020] The timing orchestration module implements a multi-dimensional scheduling strategy within the switch control plane and divides the communication cycle into a fixed time window and an elastic buffer window. The fixed window prioritizes the deterministic transmission of control instructions and synchronization signaling, while the elastic window uses a dynamic bandwidth allocation algorithm to adapt to bursty data traffic. The timing orchestration module's orchestration engine supports the priority preemption mechanism of the SRIO bus through an extended stream reservation protocol. When a high-priority task is triggered, it adjusts the packet forwarding queue and updates the multicast tree topology in real time. The global clock compensation system continuously monitors the clock offset between nodes and corrects the transmission timing deviation through software-defined delay compensation values. Further, Dual time window scheduling: A fixed window (80% of the cycle) ensures the transmission of control instructions; The elastic window (20% of the cycle) uses the weighted fair queuing (WFQ) algorithm to allocate burst traffic bandwidth; Priority preemption mechanism: Urgent tasks can interrupt the forwarding of low-priority packets, with preemption delay of <10μs.

[0021] The architecture of the RTDATA node breaks through the centralized processing mode of traditional single-board computers and includes: heterogeneous computing units; intelligent storage controllers; multi-protocol network interfaces; and runtime environment containers. The nodes integrate heterogeneous computing units, process real-time tasks through hardware accelerators, and generate compressed data streams. The intelligent storage controller manages data mirroring of local and shared storage spaces based on a cache consistency protocol. The multi-protocol network interface supports hybrid transmission of SRIO, Fibre Channel, and Ethernet. The runtime environment container provides deterministic execution guarantees, ensures time constraints for critical processes through resource isolation and real-time scheduling, and uses direct memory access technology between nodes to achieve zero-copy data transmission, reducing protocol stack processing delays. Further, Heterogeneous computing unit: CPU+FPGA+AI accelerator collaborative processing, with task division granularity reaching thread level; Intelligent Storage Controller: Maintain cache consistency based on the MESI protocol; Supports DMA direct data migration, reducing transmission delay to 1 / 5 of the traditional TCP / IP stack; Multi-protocol interface: SRIO (40Gbps), Fibre Channel (100Gbps), TSN Ethernet tri-mode adaptation.

[0022] The dynamic multicast sharing framework includes: topology discovery service; multicast tree construction algorithm; bandwidth reservation manager; and security isolation mechanism. The core lies in building an adaptive data distribution network. The topology discovery service continuously scans the status of network devices and builds a connection map. The multicast tree construction algorithm integrates path length, link load, and delay budget to generate the optimal distribution structure. The bandwidth reservation manager dynamically allocates SRIO channel resources and implements data partition protection in combination with the hardware encryption engine to ensure the physical isolation of information flows with different security levels. The framework supports the creation of temporary multicast groups on demand. Nodes within the group can trigger data push based on an event-driven model, and non-group members cannot intercept multicast content. Further, Topology discovery protocol: Real-time Link State Broadcast (RLSB) based on BGP extension, with an update cycle of ≤1ms; Multicast tree construction algorithm: Combining Dijkstra shortest path and ant colony optimization algorithm, path calculation time is less than 500μs; Security isolation mechanism: The hardware encryption engine supports the national encryption SM4 / AES-256 dual mode; it physically isolates data streams from different security domains, and cross-domain access requires dynamic key authorization.

[0023] Among them, the switch system includes: a deeply programmable data plane; a hybrid switching architecture; a quality of service engine; and a network monitoring agent. The deeply programmable architecture is used to enhance network control capabilities, and the data plane supports the injection of custom routing rules for flexible forwarding. The hybrid switching architecture selects store-and-forward or pass-through mode based on the packet type to balance latency and reliability. The quality of service engine analyzes data flow characteristics and implements differentiated processing, implementing priority queuing and fast channel allocation for real-time control instructions. The network monitoring agent collects end-to-end transmission indicators, predicts congestion risks based on machine learning models, and triggers preventive traffic shaping.

[0024] Among them, the node driver interface layer of the RTDATA node provides: virtual address mapping service; zero-copy data transmission interface; event-driven API; resource reservation manager; through virtualization technology to simplify application development, the virtual address mapping service abstracts the distributed storage space into a continuous logical view, and the application accesses physically dispersed shared data through a standardized API; the zero-copy interface bypasses the operating system protocol stack to directly operate the network hardware; the event-driven API encapsulates atomic operations such as doorbell notifications and semaphores; the resource reservation manager reserves dedicated communication bandwidth for critical tasks to ensure the transmission determinism of high-priority data streams.

[0025] Among them, the communication system also includes an exception handling system and a multi-layer fault recovery mechanism, including: link self-healing module; hybrid data verification unit; real-time log service; the link self-healing module monitors the physical connection status in real time and switches to the backup path within 50 milliseconds when a transmission interruption is detected; the data verification unit uses a hybrid verification algorithm to verify content integrity, and the overload protection system dynamically adjusts the node sending rate to prevent network congestion; the real-time log service records nanosecond timestamp event sequences, providing an accurate time benchmark for post-fault analysis, and supports online diagnostic interfaces for system health status monitoring.

[0026] The scalability of the communication system is achieved through modular design to support flexible deployment; the hybrid topology is compatible with star backbone networks and tree branch structures, and the protocol conversion gateway realizes the interconnection between SRIO and Ethernet devices; the hot-swappable management service allows online addition and deletion of nodes without interrupting running services, and the resource virtualization layer divides independent logical partitions to implement multi-tenant isolation; the system supports smooth expansion from a minimum two-node configuration to a thousand-node cluster, and each component version can be remotely and seamlessly upgraded through over-the-air download technology.

The maximum deviation is 12ns (ISO 9283 standard requires ≤50ns). Transmission determinism: End-to-end latency was recorded continuously for 24 hours, with a standard deviation of 4.7μs (compared to 82μs for traditional Ethernet). Fault recovery: When simulating an optical link break, the backup path switching time is 9.8μs, and no motion control instructions are lost during this period.

[0033] 2. Key Operations Differential protection triggering: When the line differential current exceeds the set threshold (such as 120% of the rated current), the RTDATA node completes the following actions within 50μs: Start AD sampling (sampling rate 4kHz); Calculate the differential current characteristic quantity; Generate trip command (GOOSE message); The multicast routing system constructs a minimum spanning tree to ensure that the trip command reaches the associated circuit breaker within 800μs; Fault tolerance mechanism: Link self-healing: Dual optical fiber paths (primary path delay 1.2ms, backup path 1.5ms), switching trigger conditions: Three consecutive messages are lost; Bit error rate > 1e-9; Data verification: CRC-32+SHA-256 mixed verification is adopted, and the retransmission interval of the error data packet is ≤100μs; Clock compensation: The global clock calibration module monitors temperature drift (accuracy 0.1°C). When the ambient temperature changes by more than ±5°C, it automatically adjusts the phase-locked loop parameters and clock deviation compensation. =0.15ns / °C.

[0034] 3. Measured data Action time limit: The total time from fault occurrence to circuit breaker tripping is ≤ 22ms (national standard requirement is ≤ 30ms), with communication delay reduced from 35% in traditional systems to 12%; Security isolation: Penetration testing shows that the probability of an unauthorized node intercepting a protection command is less than 1e-9, meeting the IEC 62351-6 standard. Expansion capabilities: In the online capacity expansion test, when 12 new nodes were added (total size 30 nodes), the service interruption time was 43ms and the protection function was not leaked.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
