摘　　要：针对矿井监控系统网络存在的传输速率较低问题,提出了无主式CAN总线网络结构。为了扩大CAN的网络覆盖面,采用了节点分支的方法,并对节点分支的系统地址和节点分支内地址作了详细的说明。实践证明,该种方法既增大了网络覆盖面积,又能够满足矿井监控系统实时传输的要求。The paper analyzes the problem of network of coal mine monitor system and introduces the CAN field-bus of non master. The way of node embranchment is adopted for extended CAN field-bus area, and a detailed explanation is provided of the node embranchment of the system address and the address in node embranchment. The practice proves that this way can enlarge network area and fulfil the need of real time transfers of coal mine monitor system.
