摘　　要：针对组合列车的同步制动系统结构复杂多变、分布控制的特点,设计了一种基于多智能体技术的在线诊断系统,将复杂的诊断任务逐级分解为一系列相对简单的子任务,由多个智能体协作完成诊断。给出了双层结构的多智能体诊断体系,并对其中各个组成部分的功能和设计方法进行了简单介绍。在完成诊断系统总体设计的基础上,重点研究了诊断任务的分解、分配及智能体间的协作策略等关键问题。实际应用结果证明了该技术的有效性,对保障组合列车安全运行有正面意义。In view of that the synchronous brake system of combined--train has a complex configuration and the distributed--control characterisitic, an on--line diagnosis system based on multi--agent technique is desigend, in which diagnosis tasks are decomposed into simple tasks and finished by several agents with collaboration. The diagnosis system inclueding a bi--level multi--agent system is given, and the function and design method of each part of the diagnosis system is described. Several important problems such as the mechanisms of task de- composition and distribution as well as agent collaboration are resolved. This diagnosis method is used in practice and has a satisfied result, is useful for ensuring the safety of combined--train.
