摘　　要：现有的分布式测控系统层次化网络体系结构存在着一些缺陷,难以提高分布式测控系统的实时性等关键性能参数。通过对现有的分布式测控系统层次结构存在的缺陷进行分析,提出一种分布式测控系统服务元网络体系结构,该系统服务元只提供服务,不接受服务,由各节点众多服务元组成的实时构架的分布式测控系统具有简洁、高效、可扩展和容易实现的特点。There were some limitations in current distributed measurement and control system layered network architecture. It is difficulty to improve the key parameters of real-time performance. Based on the analysis of the existent limitations in current distributed measurement and control system layered architecture, a distributed measurement and control system service unit based network architecture was proposed by this paper. In this system, Service Unit （SU） only provided services did does not receive any services. Furthermore, the distributed measurement and control system based on the Real-time Architecture （RTA） are constituted by more SU in the nodes. RTA is easy to design and to implement and has greater flexibility.
