摘　　要：随着煤矿井下现场总线系统的增多,系统的抗干扰要求越来越高。结合煤炭井下的实际情况,分析了干扰产生的原因,以脉冲群试验结论为依据,提出了一种适合煤矿井下的现场总线接口的保护设计方式。With the increase of field bus system at underground coal mine, the anti-interference requirements of system become more. Combined with the practical situation of underground coal mine, the reasons of anti- interference are analyzed. Based on the test conclusion of pulse burst, the protection design way is proposed to suitable for field bus connector at underground coal mine.
