First, aiming at the distribution of NCS, specially the multi-master system such as CAN, there is no unified network clock, so the scheduling and management are affected.

首先针对网络控制系统分布式的特点，特别是类似于CAN总线的多主系统，由于没有单一的时钟提供同步机制，影响调度管理的同步。

This paper puts forward CAN(Controller Area Network) field bus in the mine monitoring system to realize the design thought that mine monitoring system is economical, which can run at multi-master.

并将现场总线标准中的CAN用于矿井监测系统中，实现一种既能多主网络运行，又经济实用的矿井监测系统的设计思想。
