摘　　要：说明随着城市轨道交通系统在我国的蓬勃发展,传统的车载列车显示系统已经越来越不能满足安全性的要求,而通过嵌入式实时操作系统(VxWorks)开发的车载列控显示系统可以满足这方面需求,且具有多任务的特点。通过基于通信列车控制(CBTC)的车载控制器(VOBC)子系统中的车载列控显示系统的设计和实现,介绍VxWorks在车载列控显示系统中的应用。认为从多任务的角度,可以更好地解决车载列控显示系统对安全性的需求。With the development of the railway and urban rail transit system in China, the traditional on board MMI （manmachine interface） system can no longer meet the safety requirements of the railway and urban railway. However, the on board MMI system based on the real-time and multitask VxWorks could satisfy the requirements of safety-and multitask. By desigming and realizing the MMI system of the sub-system VOBC in CBTC, an application of VxWorks in on board MMI system is introduced. And from the view point of multitask, a better solution to meeting the requirements of safety is obtained.
