摘要
针对目前煤矿井下各种电气设备工作时产生的电磁干扰严重影响人员管理系统性能的问题,以煤矿人员管理系统为研究背景,对电磁干扰特性进行分析,通过设计干扰抑制电路,结合人员管理系统实际应用情况,提出一套煤矿用产品抑制电磁干扰的解决方案。解决了由于电磁干扰造成的人员管理系统设备死机、重启及通信故障等问题,大大提高了系统的抗干扰能力。
Aiming at the problem that the electromagnetic interference(Emi) caused by various electrical equipment working in coal mine has seriously affected the performance of personnel management system,analyzes the characteristics of electromagnetic interference(EMI) in the background of personnel management system in coal mine,through the design of Interference Suppression Circuit,combined with the practical application of personnel management system,a set of coal mine products to suppress electromagnetic interference solution.The problems of equipment failure,restart and communication failure caused by electromagnetic interference are solved,and the anti-interference ability of the system is improved greatly.
