摘　　要：针对煤矿井下安全,设计了一种适用于井下矿用保护系统的通信网络。系统的网络结构,采用485总线实现井下各工作通信节点互连、自动地址分配、节点数量查询、线路故障自检等功能。采用CAN总线对已分配地址的输入输出模块节点通信进行井下环境监控,同时增加中继实现远距离通信。该网络系统具有通信节点接入灵活、地址自动分配等特点,适用于井下矿用保护系统。The paper designs a system communications network for underground mine protection. The network structure of the system employs 485 Bus to achieve interconnection of communication nodes, automatic address assignment, query on the number of nodes, fault detection and other functions. The system uses CAN bus for communication between the input and output module nodes that have been assigned addresses to realize underground environment monitoring. And the system can achieve long-distance communications with repeater. The network communication system is suitable for underground mine protection owing to its flexibility, automatic address assignment and other characteristics.
