摘　　要：为了优化矿井局扇通风系统,利用变频技术和闭环控制原理,结合变频器和PLC等设备,设计了一种合理的局扇通风机变频调速系统。通过改变局扇运行转速来调节通风量,达到顺畅通风的目的。本系统适应于复杂的工作环境,抗干扰能力强,满足生产要求,并且可以改善工作环境,消除安全隐患,同时能节电运行。In order to promote Local-fan ventilation system in the mine,it can design a rational frequency-eontroling automatic control system by making full use of the inverter technology and Closed-loop control principle, with the help of inverter,PLC and so on. The system can adjust the local fan＇s speed so that it chan-ges the air volume to achieve the purpose of regulating gas con centration. The system can adapt to bad work condition, have strong anti-jamming capability and be satisfied with production requirements. And it can improve the working environment, e-liminates security risks, saves energy as well.
