摘要
针对传统高速公路机电系统存在的协议异构、资源协同效率低及通信时延高等瓶颈问题,文章提出一种基于5G通信与边缘计算的“云-边-端”协同优化架构。通过构建分层解耦的标准化技术体系,深度融合时间敏感网络(Time-Sensitive Networking, TSN)的确定性传输机制与软件定义网络(Software Defined Network, SDN)的动态资源调度策略,实现跨平台设备高效互联与计算资源弹性分配。在物理层采用混合组网方案,集成5G毫米波、NB-IoT与LoRa技术,设计嵌入式协议转换器破解既有设备接入难题。实际工程应用表明,该架构显著提升系统协同效能,协议转换效率较传统方案提高2.3倍,核心业务通信时延降低82%,极端场景下设备故障率减少64%。研究成果形成标准化接口体系与安全防护框架,为智慧高速车路协同、动态管控等业务提供高可靠通信基座,其技术路径对交通基础设施智能化升级具有示范推广价值。
To address the bottleneck issues of protocol heterogeneity,low resource coordination efficiency,and high communication latency in traditional highway electromechanical systems,this study proposes a cloud-edge-terminal collaborative optimization architecture based on 5G communication and edge computing.By constructing a hierarchical decoupling standardized technical framework that deeply integrates Time-Sensitive Networking(TSN)deterministic transmission mechanisms with Software-Defined Networking(SDN)dynamic resource scheduling strategies,efficient cross-platform device interconnection and elastic computing resource allocation are achieved.The physical layer adopts a hybrid networking solution combining 5G millimeter-wave,NB-IoT,and LoRa technologies,with embedded protocol converters designed to resolve legacy device integration challenges.Practical engineering applications demonstrate that this architecture significantly enhances system coordination efficiency,achieving 2.3 times higher protocol conversion efficiency than traditional solutions,82%reduction in core service communication latency,and 64%decrease in equipment failure rates under extreme scenarios.The research outcomes establish a standardized interface architecture and security protection framework,providing a highly reliable communication foundation for smart highway applications such as vehicle-road coordination and dynamic traffic control.The technical approach offers exemplary value for intelligent upgrading of transportation infrastructure.
