摘　　要：设计了一种基于PLC控制和MCGS监控的矿井主通风机自动倒机切换系统,该系统在运转通风机停止工作前先启用备用通风机,通过其主副风门开度的联动配合,保证风机自动切换过程供给风量和风压的稳定。应用实践表明,该系统能保证稳定送风及井下作业的安全。Designing a mine ventilator automatic regress machine switching system that based on PLC control and MCGS supervisory control, this system will let alternate ventilator begin work before operate ventilator stop work, thought out the main and secondary valve position integrated coordination, to guarantee air flowing and wind pressure steady supply in the process of fan automatic switching. The application shows, this system can insure steady supply wing and ensure safety down hole drilling operations.
