基于M-Bus和以太网的电缆远程监测系统设计

针对电缆隧道环境恶劣、容易发生火灾事故等问题，设计了一种基于M-Bus现场总线和以太网的电缆隧道分布式监测系统。监测节点完成电缆温度和烟雾的实时监测。节点间采用M-Bus总线进行数据传输，并通过以太网与上层信息管理层的互联，形成分布式监视网络。简化了系统结构。

Design of remote monitoring system for the cable based on M-Bus and ethernet technology

Countering the problems existing in the cable tunnel, such as the complex condition of running, high fire ratio, a distributed mo- nitor system about the cable tunnel based on M-Bus and Ethemet is designed. Monitor node implement inspecting the temperature, and connected each other by M-Bus. Via Ethernet, monitor host comput- er and nodes can communicate with each other directly, like a dis- tributed network. The system structure is more concise.
