Principle of On-line Monitoring System of Mine Main Ventilator and Its Applicatio

The paper analyzed design principle of software and hardware of on-line monitoring system of mine main ventilator and introduced concrete application of the system in Junde Coal Mine from points of sensor selection, communication mode, monitoring interface of industrial control computer. The practice showed that the system runs stably, decreases labor intensity, effectively avoids accidents of sudden pause of main ventilator and improves safety and reliability performance of main ventilator running.
