Vehicle-mounted Ethernet ring network management method and system

The invention provides a vehicle-mounted Ethernet ring network management method and system. The vehicle-mounted Ethernet ring network management method comprises the steps that S1, a plurality of devices form a ring topology structure based on an Ethernet cable; s2, configuring a blocking device based on the plurality of devices, and configuring a blocking port based on a port of the blocking device; s3, the blocking device detects and manages the loop, and when the loop is detected, other devices of the whole network are notified that the loop is formed; s4, starting link fault detection by the equipment after receiving the loop notification; and S5, when the fault is detected, notifying the blocking device to release the blocked port, when the link fault is detected to be recovered, notifying the blocking device to block the blocked port again, and after the fault is recovered, repeatedly triggering the steps S3 to S5. 本发明提供了一种车载以太环网管理方法及系统，包括：步骤S1：多个设备基于以太网线形成环形拓扑结构；步骤S2：基于多个设备配置阻塞设备，基于阻塞设备的端口配置阻塞端口；步骤S3：
