高速公路机电软件制品协同部署方法研究

Research on a Collaborative Deployment Method for Highway Electromechanical Software Artifacts

摘要: 针对高速公路机电系统中异构设备接入复杂、软件对象分散管理以及部署区域、安全边界和异常恢复策略难以统一约束等问题，提出一种高速公路机电软件制品协同部署方法。该方法将应用程序、AI应用、原子化服务、业务规则和设备插件等对象统一抽象为版本化制品，构建制品元模型和部署策略模型，将设备类型、接入协议、部署范围、授权条件和回滚关系等因素纳入统一描述，并设计“制品规范化生成–部署任务构建–云–边–端协同执行–运行反馈处置”的闭环流程，实现软件对象的统一审核、分发、部署和异常恢复。以梅岭隧道和老营盘隧道风速风向仪替换接入场景进行验证，并结合设备插件实例说明基于制品元数据、部署策略和运行反馈的快速回滚处置过程。结果表明，采用该方法后，设备接入周期由9天缩短至1天，应用部署时间由9 s缩短至5 s，故障响应时间由100 s缩短至10 s，分别降低约89%、44%和90%。结果说明，该方法能够提高异构设备接入效率和部署过程可控性，对高速公路机电系统软件对象统一治理具有一定参考价值。

Abstract: To address the problems of complex heterogeneous device integration, decentralized management of software objects, and the difficulty of uniformly constraining deployment areas, security boundaries, and exception recovery strategies in highway electromechanical systems, a collaborative deployment method for highway electromechanical software artifacts is proposed. The method uniformly abstracts applications, AI applications, atomic services, business rules, and device plugins as versioned artifacts, constructs an artifact meta-model and a deployment strategy model, incorporates device types, access protocols, deployment scopes, authorization conditions, and rollback relationships into a unified description, and designs a closed-loop process consisting of artifact standardized generation, deployment task construction, cloud-edge-device collaborative execution, and operation feedback handling. In this way, unified review, distribution, deployment, and exception recovery of software objects are realized. The method is verified in the replacement and integration scenario of wind speed and direction sensors in Meiling Tunnel and Laoyingpan Tunnel. In addition, a device plugin example is used to illustrate the rapid rollback handling process based on artifact metadata, deployment strategies, and operation feedback. The results show that, after adopting the proposed method, the device integration cycle is shortened from 9 days to 1 day, the application deployment time from 9 s to 5 s, and the fault response time from 100 s to 10 s, with reductions of approximately 89%, 44%, and 90%, respectively. The results indicate that the proposed method can improve the efficiency of heterogeneous device integration and the controllability of the deployment process, providing a reference for unified governance of software objects in highway electromechanical systems.
