摘要
针对车载CAN网络的实际需求设计并实现了一种遵循OSEK/VDX直接NM规范的网络管理系统。该系统以稳定的逻辑环通信为操作平台,实时更新各节点的配置信息和网络状态,通过与车载网关的通信经无线网络向远程故障诊断服务器实时上传信息,并获取下发至相关节点的命令和查询报文。本文所提出的节点按序上线建立稳定逻辑环通信的机制,通过在相关项目中的实际应用得到了充分验证,系统有效实现了对车载CAN网络的实时监控。
A network management system complied with the specification of OSEK/ VDX direct NM for actual demand of the in-vehicle CAN network is designed and implemented.This system uses the stable logical ring communication as an operation platform,which updates the nodes' configurations and the network states.The system uploads information to the remote fault diagnostic service by in-vehicle gateway through the wireless network and receives command and inquiry message to relative nodes.The mechanism that nodes establish a stable logical ring under the order proposed in this paper was verified by application in relative projects.The system designed in this paper implements the real-time monitoring on the in-vehicle CAN network effectively.
