针对现代智能建筑中的热量表抄表问题,设计了基于M-Bus总线的远程抄表系统。详细介绍了集中器的硬件设计,以及通信协议的制定,同时对远程管理软件系统的结构和功能进行了初步讨论。实验室环境下的模拟测试表明,所设计的远程抄表系统在大负载情况下,通信和供电均正常,远程管理软件系统也能够正常工作,完全满足实际工程应用的需求。
In view of the problem of meter reading in modern intelligent buildings, a remote meter reading system based on M-Bus is designed. The hardware design of concentrator and the development of communication protocol are introduced in detail. At the same time, the structure and function of remote management software system are discussed. The simulation tests in the laboratory environment show that the remote meter reading system designed under normal conditions has normal communication and power supply under heavy load and the remote management software system can work normally to meet the requirements of practical engineering applications.
