摘　　要：ＭＡＰ的应用层提供了多种通信标准，其中ＭＭＳ（制造报文规范）是一种能够满足工厂环境中各种自动化设备之间通信需要的协议。在我国，ＢＩＴＢＵＳ网已被大量使用于底层设备互连，在技术和实现上都较成熟。本文以ＭＡＰ，ＢＩＴＢＵＵ网络体系结构和协议为基础，根据网络互连方法和原则，构造了一个应用层同关，提出了网关的物理模型，从而给出ＭＡＰ网与ＢＴＴＢＵＳ网互连的一种设计方案及在ＡＭＸ实时多任务环境下的互连实现。In the application layer, MAP provides a variety of communication standards Among them,MMS(Manufacturing Message SpecifiCation)is such a protocol that can meet the communication requirements between various automation devices in factory environments. BITBUS network is widely used in our country as a field bus protocol,and the technique has become mature. Based on the network syStem structures and the protocols,this paper describes a gateway on the application layer and a physical model of the gateway through the interconnection method Thus a design for the interconnection of MAP network and BITBUS network is given. Based on the AMX Real Timle Multitask Operating System,aninterconnection is also provided.
