摘　　要：介绍了在测量与仪表技术领域,欧洲新型总线结构一仪表总线(M-bus)在远程自动抄表系统中的应用。M-bus仪表总线属于局域网,被用于连接远程监控计算机和工作站、测量仪表等设备,以便实现资源共享和数据传输。家用公共事业仪表通过扩展M-bus总线, 使其具有与M-bus仪表总线通讯的功能,从而实现远程抄表。概述了该仪表总线的OSI模型及其通讯协议,分析了总线传输机制,介绍了仪表总线的实际应用。它的应用将简化系统设计、提高性能价格比和运行可靠性。In the field of measurement arid instrumentation, a new field bus, i.e. Meter bus (M-bus) is appearing in Europe. There are more and more applications in remote automation meter reading system. Because its application leads to simplify the system design, improves the ratio of price and performance and increases the running liability. Meter bus belongs to Local Area Net-work, and it's often used to connect with the remote monitors, the workplaces and the measurement instruments in order to share with resource and data transmission. The house-used public business meters have the performance of communication with M-bus and realize the remote meters reading by extending the M-bus. The OSI model of the M-bus and communication protocol are presented, transmission mechanism is analyzed, and the application in the house-using public business is introduced.
