[0002] With the development of technology, increasingly complex business data encounters challenges such as dense equipment, semi-enclosed communication environments, strong interference, and long distances. For example, highway tunnel electromechanical systems are characterized by dense equipment, complex business types, and semi-enclosed communication environments with strong interference and long distances. Traditional wireless communication technologies struggle to meet the real-time and reliability requirements of engineering applications. Technologies like Wi-Fi and Bluetooth have shortcomings in signal penetration, resistance to motor interference, and controllable transmission delay, making it difficult to support the diverse business needs of tunnel electromechanical systems. In typical scenarios such as emergency response, intelligent lighting, and structural health monitoring, issues such as delayed command response, concurrent access congestion, and high energy consumption are prone to occur. Furthermore, existing tunnel communication systems often rely on a single link. Therefore, the stability of communication links is poor when transmitting data in complex environments using existing technologies.

[0003] Therefore, existing technologies have shortcomings and need to be improved and developed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a data communication method, device, terminal and storage medium based on star flash, which addresses the above-mentioned defects of the prior art and aims to solve the problem of poor stability of the communication link when transmitting data in complex environments.

[0005] The technical solution adopted by this invention to solve the technical problem is as follows: A data communication method based on star flash, wherein the method includes: Determine the target data model of the business data to be transmitted, and encapsulate the business data according to the target data model to obtain encapsulated business data; The performance indicators of several connected communication links are collected, and the link health status of each connected communication link is obtained based on the performance indicators.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0024] Highway tunnels are critical infrastructure in transportation networks, and the safe operation of their electromechanical systems relies on highly reliable communication. With the development of intelligent transportation, tunnel electromechanical systems are evolving towards multi-service integration and intelligent linkage, placing higher demands on communication latency, reliability, and large-scale access capabilities.

[0025] The semi-enclosed, highly interference-prone, and long-distance operating environment of tunnels poses significant challenges to traditional wireless communication technologies. Technologies such as Wi-Fi and Bluetooth have shortcomings in signal penetration, resistance to motor interference, and controllable transmission latency, making it difficult to support the diverse service needs of tunnel electromechanical systems. In typical scenarios such as emergency response, intelligent lighting, and structural health monitoring, problems such as delayed command response, concurrent access congestion, and high energy consumption are prone to occur. Existing tunnel communication systems mostly rely on single links, lacking a unified communication framework and coordination mechanism, which restricts the integrated management and control of electromechanical systems and the construction of a digital infrastructure.

[0026] SparkLink, a next-generation short-range communication technology, adopts a "one standard, multiple modes" architecture, combining ultra-low latency, high reliability, and large-scale connectivity, providing a new technical path for communication in specialized industries. Specifically, the SLB mode achieves deterministic low-latency transmission of less than 20μs, while the SLE mode features large connectivity and low power consumption. Combined with Polar coding and HARQ retransmission mechanisms, it significantly improves link reliability in environments with strong interference. However, for the typical "semi-enclosed, highly interference-prone, multi-service convergence" scenario of highway tunnel electromechanical systems, a systematic communication framework design is still lacking. The engineering potential of SparkLink in multi-service adaptation and multi-link collaboration remains to be further explored.

[0027] To address the aforementioned issues, this application proposes a method for constructing a communication link framework for highway tunnel electromechanical systems based on star-flash technology, providing an engineering-implementable wireless communication support solution for highway tunnel electromechanical systems. By constructing an SLB / SLE dual-stack collaborative communication mode, combined with Polar coding enhancement, OFDMA resource scheduling, and a reliable transmission mechanism, unified wireless transmission is achieved for various electromechanical services, including tunnel emergency response control, intelligent lighting dimming, structural and environmental monitoring, and mobile inspection. Research and analysis show that this framework can effectively improve the stability, latency controllability, and service reliability of communication links in highway tunnel environments, providing an engineering-implementable communication solution for the digital and intelligent construction of highway tunnel electromechanical systems.

[0028] For tunnel electromechanical communication, highway electromechanical systems can be divided into three functional systems: monitoring, toll collection, and information. These systems respectively undertake tasks such as road operation perception, toll management, and traffic information services, encompassing key equipment such as traffic monitoring, electronic toll collection, and information dissemination. While these three systems differ in their business models and operational scenarios, they all place high demands on the communication system in terms of real-time performance, reliability, and data transmission efficiency. Highway communication systems consist of wired and wireless communications. Wired communication primarily handles highly reliable data transmission from fixed electromechanical equipment, while wireless communication serves vehicles and mobile terminals, providing dynamic information and secure communication support for road operations.

[0029] The tunnel operating environment is characterized by enclosed spaces, restricted traffic organization, and complex operation and management, significantly increasing the difficulty of emergency response and traffic control after an accident. This places higher demands on the real-time performance and reliability of communication, monitoring, and linkage control systems. The management of tunnel electromechanical equipment also places higher demands on the real-time performance and reliability of communication, monitoring, and linkage control systems. This application classifies tunnel electromechanical services into five categories according to application scenarios, with different communication requirements for different services, as shown in Table 1.

[0030] Table 1

[0031] In the electromechanical systems of highway tunnels, different service types, due to their varying functional attributes, impose tiered technical requirements on the communication system in terms of latency, reliability, concurrency, and energy consumption. Emergency response control primarily involves critical life-safety equipment such as jet fans, smoke exhaust fans, and fireproof rolling doors. Its command triggering is highly real-time, requiring communication links with millisecond-level ultra-low latency and reliable command delivery capabilities to ensure rapid and efficient handling of fires or traffic accidents. Intelligent lighting control targets large-scale LED lighting fixtures, requiring synchronized adjustment of light intensity across the entire tunnel under traffic flow triggering. The communication system should support high-density device access and multicast consistency control capabilities to avoid "wave-like" light response. Environmental and structural monitoring relies on numerous CO / VI sensors and structural health monitoring nodes for cracks and settlement. Its data is small and uploaded periodically; the communication system should balance massive concurrency with low power consumption and long lifespan to achieve continuous and stable safety awareness. Mobile inspection and high-definition video transmission services typically rely on unmanned inspection robots or drones, characterized by high bandwidth and high mobility. These require communication links to provide stable and continuous video stream transmission and high-speed, uninterrupted connectivity. Seamless equipment maintenance involves tasks with large data volumes, such as log downloads and firmware upgrades, requiring communication links with high-speed file transfer and secure discovery access capabilities to reduce manual maintenance workload and improve operational efficiency.

[0032] The following describes a data communication method, apparatus, terminal, and storage medium based on StarSpark, according to embodiments of this application, with reference to the accompanying drawings. Addressing the problem of poor communication link stability in complex environments during data transmission in related technologies mentioned in the background, this application provides a data communication method based on StarSpark. In this method, a target data model of the service data to be transmitted is determined; the service data is encapsulated according to the target data model to obtain encapsulated service data; performance indicators of several connected communication links are collected; the health status of each connected communication link is obtained based on the performance indicators, and the connected communication links include StarSpark links; a target communication link is selected based on the link health status; and the service data is transmitted to the receiving end based on the target communication link. This application improves the stability of communication links during data transmission in complex environments by employing several connected communication links, with StarSpark links added to these links, and using StarSpark links as a guarantee under the premise of multi-link fusion.

[0033] Please see Figure 1 , Figure 1 This is a flowchart of the star-flash-based data communication method in this invention. For example... Figure 1 As shown, the data communication method based on star flash according to the embodiments of the present invention includes: Step S100: Determine the target data model of the service data to be transmitted, and encapsulate the service data according to the target data model to obtain encapsulated service data.

[0034] In this embodiment of the application, the method further includes: after determining that physical layer access with the StarSpark gateway has been completed, performing two-way identity authentication with the StarSpark gateway; after the identity authentication is successful, negotiating and distributing session keys with the StarSpark gateway, so as to use a high-strength symmetric encryption algorithm to encrypt the business data across the entire link, thereby forming a StarSpark link.

[0035] SparkLink technology, through the introduction of ultra-short frame structure, Polar coding enhancement, frequency hopping signal splicing and centralized scheduling mechanism, shows significant advantages in anti-interference capability, latency performance and synchronization accuracy. The specific advantages of SparkLink technology in highway tunnel scenarios are shown in Table 2.

[0036]

[0037] Specifically, firstly, ultra-low latency SLB supports emergency response and real-time data transmission. The StarScan SLB mode, based on an ultra-short frame structure and a deterministic scheduling mechanism, can achieve end-to-end ultra-low latency transmission, meeting the millisecond-level response requirements of tunnel emergency response control, and providing stable, low-latency data transmission capabilities for inspection robots and video surveillance. In tunnel emergency response and real-time data transmission scenarios, the SLB end-to-end latency can be expressed as: (1) in, For transmission delay (ultra-short frame transmission time), For deterministic scheduling waiting delay, For channel propagation delay, This is for the delay in receiving and decoding.

[0038] In SLB mode, due to the adoption of centralized scheduling and fixed time slot allocation, further constraints can be imposed: Thus, the upper bound of the time delay is obtained: (2) This upper limit of latency is the theoretical basis for SLB's support of millisecond-level emergency response in tunnels.

[0039] Secondly, the high connectivity of the SLE network supports a large number of monitoring nodes within the tunnel. Environmental and structural monitoring nodes are densely distributed within the tunnel, covering various types of equipment including CO / VI, strain, seepage, and energy consumption monitoring. The StarScan SLE mode supports high-density concurrent node access and stable reporting, effectively reducing the probability of collisions and improving link resource utilization efficiency through a centralized scheduling mechanism. Let N be the number of terminal nodes simultaneously accessing the SLE network, and within one scheduling cycle... The maximum number of connections that the system can support is: (3) in, For a complete scheduling cycle, This represents the minimum scheduling interval for a single section.

[0040] Because SLE employs a low-rate, compact frame structure and a batch scheduling mechanism, it enables: (4) This enables stable access for thousands or even tens of thousands of nodes. Let the tunnel length be L and the node deployment density be λ, then the total number of access nodes is: (5) The system must meet the following requirements for stable operation: (6) Third, Polar code enhancement strengthens anti-interference and reliability. Addressing the complex electromagnetic interference caused by high-power electromechanical equipment within tunnels, XingShan employs Polar channel coding and frequency hopping mechanisms based on the 5G architecture, significantly improving receiver sensitivity and error resilience, achieving stable long-distance, low-packet-loss transmission. Let the original binary input channel be W; through channel combining and splitting operations, a set of polarized sub-channels is obtained: (7) As the code length \(N = 2^n\rightarrow\infty\), the sub-channel capacity satisfies: (8) where is the sub-channel capacity, is an arbitrarily small positive number. This formula is the theoretical basis for Polar to approach the Shannon limit in a strong interference channel.

[0041] Fourth, OFDMA concurrent scheduling can ensure the orderly transmission of multiple services. SparkLink adopts an OFDMA-based concurrent scheduling mechanism to finely divide and allocate on-demand the air interface time-frequency resources, achieving the orderly parallel transmission of multiple terminals and multiple services. This mechanism effectively reduces the access conflict and retransmission probability caused by the simultaneous reporting of multiple nodes through deterministic resource scheduling, and suppresses link congestion and delay fluctuations. Under the condition of the parallel operation of multiple services in the tunnel electromechanical system, OFDMA concurrent scheduling improves the resource utilization efficiency and the predictability of service transmission, providing support for stable communication in complex environments.

[0042] Fifth, unified payload and high-precision synchronization support multi-service fusion and collaborative control. SparkLink realizes the fusion bearing of multiple services such as video backhaul, inspection log transmission, and policy distribution under the same network architecture through a unified streaming and file payload model, effectively reducing the complexity of the system architecture and the operation and maintenance costs brought by the parallel deployment of multiple networks. At the same time, relying on the centralized scheduling and high-precision clock synchronization mechanism, SparkLink can achieve microsecond-level time consistency, ensure the collaborative acquisition and linkage control of multiple devices in the tunnel scenario, meet the requirements of service timing accuracy such as emergency linkage and intelligent lighting, and provide reliable communication and synchronization support for future high-precision collaborative applications.

[0043] It can be seen that the advantages of SparkLink are adapted to the tunnel scenario of "strong interference + multi-service fusion", and can solve the three major pain points of traditional wireless technologies: poor signal penetration, weak anti-motor interference, and uncontrollable delay.

[0044] [[ID=2i]]In the special scenario of highway tunnels with the characteristics of "semi-closed, strong interference, and long distance", SparkLink technology provides significant technical compensation and performance improvement for the key bottlenecks of traditional wireless communication technologies, such as signal attenuation, insufficient ability to resist strong motor noise interference, and difficulty in stable control of delay. Based on its highly reliable, low-delay, and strong robustness architecture, it can achieve full-domain coverage and efficient communication support for multiple service scenarios in the tunnel.

[0045] First, Tunnel Emergency Linkage Control. As the core business scenario of the tunnel electromechanical system, tunnel emergency linkage control requires millisecond-level linkage control of key facilities such as jet fans, smoke exhaust fans, fireproof rolling shutter doors, and traffic lights in case of fire or traffic accidents to ensure the timeliness and safety of emergency response. By introducing the SLB (SparkLink Basic) protocol framework, SparkLink technology can maintain stable link quality in strong electromagnetic noise environments such as fan startup, relying on its ultra-low latency characteristics and the high-robustness channel coding mechanism based on Polar codes. By enabling the Reliable mode, the system can achieve reliable transmission of key control instructions, effectively replacing the traditional linkage control method that relies on fire-resistant optical cables, providing higher availability and engineering economy guarantee for tunnel emergency communication.

[0046] Second, Intelligent Lighting Dimming System. Based on the data of the brightness sensor outside the tunnel and traffic flow monitoring, the tunnel intelligent lighting system needs to adjust the brightness of thousands of LED lamps in the tunnel in real-time and continuously without steps to achieve the adaptive lighting strategy of "lights on when vehicles come, lights off when vehicles leave". With the high-concurrency access capability of the SLE protocol, SparkLink technology enables a single gateway to stably connect and manage hundreds of lamps, significantly improving the network bearing efficiency of the lighting system. In addition, by adopting the multicast communication mechanism, SparkLink can achieve synchronous brightness adjustment of the entire section of tunnel lighting facilities, fundamentally avoiding the "wave-like" delay phenomenon caused by the逐灯响应 (逐灯响应 should be replaced with per-lamp response in English) in traditional wireless solutions, thus ensuring the spatio-temporal consistency of lighting changes and the continuity of the driving visual experience.

[0047] Third, Structural Health and Environmental Monitoring. In the monitoring of tunnel structural safety and environmental quality, a large number of wireless sensors are required to continuously collect and report key parameters such as tunnel wall cracks, structural settlement, and visibility. Based on the ultra-low power consumption characteristics of the SLE protocol, SparkLink technology enables sensor nodes to operate stably for several years under battery power, significantly reducing the maintenance cost and deployment difficulty. In addition, SparkLink adopts a frequency-domain fine scheduling mechanism based on OFDMA, which can effectively divide and allocate available spectrum resources to each terminal in high-concurrency scenarios where the number of sensors reaches hundreds to thousands, thus avoiding co-frequency competition and upload conflicts. This mechanism ensures that the multi-source monitoring data can still maintain smooth links and controllable delays when reported simultaneously, providing high-reliable data collection capabilities for tunnel structural health monitoring and environmental safety warning.

[0048] Fourth, mobile inspection and video transmission. In intelligent tunnel inspection scenarios, inspection robots or drones need to transmit high-definition visible light and infrared thermal imaging video in real time during movement to support tasks such as structural defect identification, environmental anomaly detection, and operational status assessment. StarScan technology, relying on the high bandwidth characteristics of the SLB protocol and its streaming model oriented towards continuous media, can simultaneously carry the stable transmission of multiple high-definition video streams. Thanks to its highly robust air interface design and fast link maintenance mechanism, even under high-speed movement conditions, the communication link can maintain low latency and high integrity, avoiding the frequent blurry images and link interruptions that occur in traditional wireless systems, thus significantly improving the real-time performance and reliability of inspection operations.

[0049] Fifth, seamless operation and maintenance of electromechanical equipment. During the operation and maintenance of tunnel electromechanical equipment, maintenance personnel often need to perform operations such as log downloading, parameter verification, and firmware upgrades on various devices installed on tunnel walls or gantry frames. StarShine technology, through its Secure Discovery mechanism and File Model, enables secure, contactless data interaction with high-altitude equipment. Maintenance personnel do not need to perform high-altitude operations or disassemble equipment; they can complete high-speed data transmission "remotely" using only a ground-based handheld terminal. Relying on the high throughput capacity of the StarShine link, the system can stably transmit GB-level log files in a short time, with transmission efficiency far exceeding traditional short-range wireless technologies such as Bluetooth, thus significantly improving the safety, convenience, and efficiency of tunnel equipment operation and maintenance.

[0050] This application constructs a layered architecture of "end-to-pipe-to-cloud-to-application" covering device terminals, wireless transmission networks, cloud platforms, and business application layers, such as... Figure 2 As shown.

[0051] The SparkLink Access layer serves as the communication foundation of the entire system, responsible for providing reliable wireless access capabilities in typical tunnel environments characterized by strong interference, long distances, and high-speed movement. This layer utilizes key technologies such as Polar code channel coding, IR-HARQ hybrid retransmission mechanisms, and link health awareness to achieve noise immunity, error correction enhancement, and high-precision synchronization, ensuring link stability and robustness at the physical layer. Simultaneously, SLB and SLE constitute differentiated access modes: SLB provides low latency and high bandwidth capabilities to support control commands and video streaming services; SLE is geared towards low-power, high-connectivity scenarios, suitable for large-scale sensor access. This layered access mechanism enables efficient transport of different service types on the same wireless infrastructure.

[0052] The basic service layer (KaihongBUS) is equivalent to the core scheduling and intelligent management module of the system, providing a unified network service abstraction for the upper layers. The Kaihong BUS converged communication framework achieves dynamic path selection, load distribution, and reliable switching across links by unifying and coordinating the abstraction of heterogeneous links such as Wi-Fi, Ethernet, BLE, and Starlink. Based on real-time link awareness and service characteristic matching, the system can optimize data transmission paths across multiple sources and types of links, effectively improving the overall availability, robustness, and resource utilization efficiency of communication. Multi-link concurrency and redundant transmission mechanisms further enhance transmission stability under high interference or link fluctuation conditions, providing crucial support for high reliability, low latency, and large-scale service access in tunnel scenarios.

[0053] The data model and profile layer encapsulate lower-layer access capabilities using a unified abstract model, enabling cross-device and cross-service interoperability. This layer defines four data models: Message, Stream, File, and Byte transparent mode, supporting business requirements such as short command control, continuous media transmission, large file distribution, and compatibility with older devices. The profile configuration framework standardizes data formats, interaction protocols, and capability declarations, allowing multiple types of services to be encapsulated and parsed within a standardized "data container" framework. This abstract design enables plug-and-play capabilities for upper-layer applications, reducing the business's dependence on underlying communication details.

[0054] The intelligent application layer addresses typical business needs in tunnel scenarios, including emergency response control, intelligent lighting regulation, structural and environmental monitoring, and operation and maintenance and video inspection functions. This layer enables flexible deployment and expansion of business logic by calling a unified interface between the data model and the basic service layer.

[0055] This application presents a dynamic communication process model for the entire business process, based on a "terminal-pipe-cloud-application" architecture. It divides the communication process into four key, mutually coordinating stages: device access, data encapsulation, link fusion scheduling, and reliable physical layer transmission. This systematically reveals the inherent logic behind achieving low-latency, high-reliability, and strong anti-interference transmission for various types of electromechanical services in complex tunnel environments. Through this phased mechanism, the StarSpark communication framework not only achieves unified transport of heterogeneous services but also provides an implementable path for multi-link collaboration and engineering-level reliability assurance.

[0056] The first phase is the security and fast access mechanism. In the initial stage of the communication process, the system needs to complete rapid discovery, authentication, and secure association between the terminal device and the StarScan gateway to ensure the reliability and real-time nature of subsequent data interactions. This phase adopts an SLB / SLE collaborative access mechanism. SLE mode primarily handles low-power, high-efficiency device discovery and initial access, achieving microsecond-level handshake responses through a dedicated broadcast channel, significantly shortening device network access latency. SLB mode provides strong security during the connection establishment phase. After completing physical layer access, the system executes a mandatory two-way authentication process, effectively preventing unauthorized device access and fake base station attacks through a two-way authentication mechanism between the terminal and the gateway. After successful authentication, the system completes session key negotiation and distribution, employing a high-strength symmetric encryption algorithm for end-to-end encryption of subsequent communications, thereby building a reliable and controllable wireless access foundation in the highly security-sensitive tunnel scenario. The specific details of the secure and fast access process are as follows: Figure 3 As shown.

[0057] In one embodiment of this application, the step S100 of "determining the target data model of the service data to be transmitted" specifically includes: Determine the service type to which the service data to be transmitted belongs; Search a preset data model matching table, which includes the correspondence between business types and data models; The business type of the business data to be transmitted is matched with the business type in the data model matching table to obtain the target business type that has been successfully matched; The data model corresponding to the target business type is used as the target data model for the business data to be transmitted.

[0058] For example, during matching, matching can be based on similarity, that is, the similarity between the business type to which the business data to be transmitted belongs and each business type in the data model matching table is calculated, and the business type with a similarity greater than a preset threshold is taken as the target business type.

[0059] After completing secure access, this application puts business data into the data model encapsulation stage. Through the data model encapsulation mechanism, it achieves unified expression and standardized carrying of multiple types of business data while shielding the underlying communication details.

[0060] In this embodiment, the service type includes at least one of control services, continuous media and video backhaul services, and large data volume services; the data model corresponding to the control services is a message model, the data model corresponding to the continuous media and video backhaul services is a stream model, and the data model corresponding to the large data volume services is a file model; the message model is encapsulated based on adding message headers and sequence control mechanisms, and the stream model is encapsulated based on data slicing and pipelined transmission mechanisms.

[0061] This application declares business attributes through a profile description file and automatically matches the appropriate data model based on the business's latency sensitivity, data continuity, and reliability requirements. Control-type services and status commands are encapsulated using a message model, ensuring the sequential and reliable delivery of commands by adding necessary message headers and sequence control mechanisms. Continuous media and video backhaul services use a stream model, improving throughput efficiency through data slicing and pipelined transmission mechanisms. Large-volume tasks such as log downloads and firmware upgrades are carried using a file model. The business data, after model matching, is uniformly encapsulated into service data units (SDUs) and delivered down to the communication scheduling and transport layer, thereby decoupling the application from physical communication. The specific data model encapsulation is as follows: Figure 4 As shown.

[0062] like Figure 1 As shown in the embodiments of the present invention, the data communication method based on star flash further includes: Step S200: Collect performance indicators of several connected communication links, evaluate them based on the performance indicators, and obtain the link health status of each connected communication link, including the Star Flash link.

[0063] In this embodiment of the application, step S200 specifically includes: Step S210: Collect performance indicators of several connected communication links, including at least one of signal strength, packet loss rate and round-trip time; Step S220: According to the preset weighted evaluation model, the performance indicators of each connected communication link are evaluated by weight to obtain the link health status of each connected communication link.

[0064] Specifically, after data encapsulation, the communication process enters the multi-link fusion scheduling phase, which is uniformly managed by the KaihongBUS converged communication framework in the basic service layer. Its core function is to perform real-time sensing, performance evaluation, and dynamic scheduling of various available links such as Starfly, Wi-Fi, and Ethernet, constructing an adaptive multi-link communication system. The system collects key performance indicators of each link through a periodic probe mechanism, including signal strength, packet loss rate, and round-trip latency, and calculates link health indicators based on a weighted evaluation model.

[0065] like Figure 1 As shown in the embodiments of the present invention, the data communication method based on star flash further includes: Step S300: Select the target communication link based on the link health status.

[0066] In this embodiment of the application, step S300 specifically includes: Step S310: Obtain the link health status of the current communication link among the connected communication links. If the link health status of the current communication link is greater than the first preset threshold, then the current communication link is used as the target communication link. Step S320: If the link health status of the current communication link is less than or equal to the first preset threshold, then obtain the link health status of each backup communication link in the connected communication links. Step S330: If there are several backup communication links whose link health status is greater than the second preset threshold, then determine the target communication link among the several backup communication links whose link health status is greater than the second preset threshold.

[0067] Specifically, during operation, the scheduling module dynamically selects the optimal transmission path based on service QoS requirements and link health status. When the main link performance degrades and the backup link has better transmission conditions, the system can complete link switching or parallel scheduling without affecting upper-layer applications, thereby significantly improving the overall robustness and continuity of the communication system under strong interference and complex operating conditions. The multi-link fusion scheduling process is as follows: Figure 5 As shown.

[0068] This application aims to improve the overall reliability and resilience of communication networks by constructing a multi-link redundancy guarantee system.

[0069] like Figure 1 As shown in the embodiments of the present invention, the data communication method based on star flash further includes: Step S400: Transmit the service data to the receiving end based on the target communication link.

[0070] In this embodiment of the application, step S400 specifically includes: Step S410: If the target communication link is a Starlink link, then receive the transport block scheduling instruction issued by the MAC scheduling layer, and at the same time obtain the time and frequency resources allocated based on the centralized scheduling strategy to determine the specified subcarrier and time slice. Step S420: Access the beacon of the wireless channel, perform Polar code encoding on the service data to obtain the encoded service data, and modulate and map the encoded service data into QAM symbols; Step S430: Obtain the wireless signal based on the QAM symbol, and transmit the wireless signal to the receiving end through the wireless channel; Step S440: If a positive response is received from the receiving end, the current transmission ends. Step S450: If a negative response is received from the receiving end, the incremental redundancy packet corresponding to the service data is obtained, and the incremental redundancy packet includes necessary redundancy information. Step S460: Send the incremental redundancy packet to the receiving end until a positive response is received from the receiving end.

[0071] Specifically, the final stage of the communication process focuses on achieving reliable transmission at the physical layer in a highly interference-prone environment. This stage utilizes OFDMA fine-grained resource scheduling, Polar channel coding, and a Hybrid Automatic Repeat Request (HARQ) mechanism to achieve highly reliable data transmission within millisecond-level superframe periods. During transmission, the gateway node first allocates time-frequency resources based on a centralized scheduling strategy, specifying which subcarriers and time slices the terminal will transmit data on. Subsequently, the service data undergoes Polar coding, significantly improving error resilience through the introduction of redundancy check and channel polarization mechanisms. When the receiver detects a transmission error, the system triggers the HARQ incremental redundancy retransmission mechanism, retransmitting only necessary redundant information and performing soft information merging and decoding at the receiver, thereby significantly improving the transmission success rate without significantly increasing latency. This mechanism provides crucial technical support for high-interference, high-reliability communication in tunnel environments. The specific details of the physical layer high-reliability transmission mechanism are as follows: Figure 6 As shown.

[0072] This application improves the stability and reliability of data transmission by introducing a dual-stack SLB / SLE collaborative mechanism and combining it with Polar coding enhancement, OFDMA resource scheduling, and reliable transmission mode.

[0073] This application addresses the high requirements for real-time and reliability of communication in the semi-enclosed, high-interference, and long-distance environments of highway tunnel electromechanical systems. It proposes a converged communication link framework for highway tunnel electromechanical systems based on Starflash technology. By introducing a dual-stack collaborative mechanism of SLB / SLE and combining Polar coding enhancement, OFDMA resource scheduling, and reliable transmission mode, it realizes unified wireless transport for various electromechanical services such as tunnel emergency response, intelligent lighting, structural and environmental monitoring, and mobile inspection.

[0074] The communication link convergence framework proposed in this application can effectively improve the stability and latency controllability of wireless communication links under complex electromagnetic interference conditions, meeting the comprehensive requirements of key tunnel electromechanical services for low latency, high reliability, and multiple connections. It provides technical support for reducing reliance on a single wired communication method and improving system deployment flexibility. This framework possesses good engineering adaptability and scalability, and can be smoothly integrated with existing tunnel electromechanical systems, providing an engineering-implementable communication solution for the digital and intelligent upgrading of highway tunnel electromechanical systems.

The evaluation module 200 is used to collect performance indicators of several connected communication links, evaluate them based on the performance indicators, and obtain the link health status of each connected communication link, including the Star Flash link. Selection module 300 is used to select a target communication link based on the link health status; The transmission module 400 is used to transmit the service data to the receiving end based on the target communication link.

[0076] It should be noted that the foregoing explanation of the embodiment of the star-flash-based data communication method also applies to the star-flash-based data communication device of this embodiment, and will not be repeated here.

This application, by employing several connected communication links and adding a star-flash link to them, improves the stability of communication links during data transmission in complex environments under the premise of multi-link fusion, using the star-flash link as a guarantee.
