摘　　要：针对目前列车网络控制系统的需要,设计了列车网络控制系统中MVB与RS485通信互连的网关。重点介绍了基于VXWORKS操作系统、COLDFIRE处理器平台实现RS485-MVB网关的软、硬件设计方案与技术。该网关系统充分利用了COLDFIRE处理器的片上资源及其优势,能很好地满足RS485-MVB网关系统的要求,具有较高的可靠性和较强的实用性。According to the current needs of train network control system, this paper designs gateway communicated between MVB and RS485. The paper puts emphasis on the scheme and technology of software and hardware of RS485-MVB gateway, which is based on VXWORKS operating system and COLDFIRE processor platform. The gateway system makes full use of the resources and advantages of the COLDFIRE processor-chip to meet the needs of the RS485-MVB gateway system and has the advantages of high reliability and applicability.
