摘　　要：针对煤矿井下CAN通信设备大于110个或传输距离大于10 km的情况,设计了一套中继器,采用飞思卡尔最新的以Cortex-M7为核心的KV5x系列芯片,以保障运算速度与可靠性。该设备不但增加了通信设备的数量,还延长了数据传输的距离,同时通信速率自适应能防止某节点的故障信号影响到整条线路。For CAN communication equipment in underground coal mine is larger than 110 or transmission distance more than 10 km., design a repeater, the fly think of Carl the latest to Cortex-M7 as the core KVSx series chip, guarantee the operation speed and reliability. Not only increase the number of communication equipment, but also extend the data transmission distance, while the communication rate adaptive can prevent a node fault signal affects the whole line.
