摘　　要：针对HX_D3C机车MVB/RS485网络中断造成的制动机不缓解故障进行原理分析,探讨了MVB/RS485网络的功能及可靠性,指出其作为HX_D3C机车唯一方式传输EBV激活信号的不足,并提出了当MVB/RS485网络中断时能使机车维持运行回机务段的建议措施。This paper analyzes the principle of the brake not release caused by the interruption of MVB/RS485 network on HXD3 Clocomotive,and investigates the function and reliability of MVB/RS485 network,and points out that it is unreliable as the only way to transmit activation signal of EBV,and proposes the solution that the locomotive can maintain the running back to the locomotive depot when MVB/RS485 network is interrupted.
