摘　　要：面向服务于航空试验的测控系统，提出了通过构架分布式测控环境的方法实现航空测控系统集成的构想，分析了航空试验测控系统中实时通信的特殊性，设计了基于以太网络的实时通信协议，并在此协议之上实现了分布式测控环境下的实时通信服务。Aimed at the Computer Automated Measurement and Control (CAMAC) system of aeronautic tests, a scheme is proposed to realize the aeronautic CAMAC system integrating by building the Distributed Measuring and Controlling Environment (DMACE). Through analyzing the specialization of the real time communication in aeronautic testing, a real time communication protocol based on the Ethernet is designed, thus realizing the real time communication services under DMACE. The real time communication protocol is based on Ethernet 802.4, Token ring 802.5, TCP and UDP. In order to design it, the authors also use UDP protocol, Token, data transformation technology, network accessing technology and error controlling technology. The basic real time communication service under DMACE is realized by real time port service.
