Abstract: Siemens S7-300 series PLC and inverter were used to develop control system to realize precise control of coal mine
ventilation system. The upper computer of the system used DELTA touch screen, the system control algorithm used the relationship
between the main ventilator air pressure and air volume to achieve PID control, through the control of the frequency
converter, so as to realize the real-time dynamic adjustment of the ventilation volume and realize the reliable and stable operation
of the coal mine ventilator.

Key words: PLC; variable frequency speed regulating; ventilator; frequency converter; touch screen
