HX_D2型机车制动系统CAN网络故障原因分析与优化设计

Fault analysis and optimal design of CAN network for braking system on type HX_D2 locomotive

HX_D2型机车两节机车的制动系统通过CAN网络进行信息的传递并可互为备用。CAN网络上连接着多个节点设备,任一节点故障或节点的通信故障等都会导致制动控制单元诊断出CAN网络故障。针对此问题,对HX_D2型机车制动系统CAN网络进行分析,并提出了优化设计方案。

The braking systems of two locomotives of type HX_D2 locomotive communicates through the CAN network and can be backup of each other. The CAN network is connected with multiple node devices, and any node failure or communication fault will cause the brake control unit to diagnose the CAN network fault. In view of this problem, the CAN network of type HX_D2 locomotive’s braking system is analyzed, and the optimized design scheme is put forward.
