In order to realize the real-time monitoring of the coal mine ventilator, the finite state machine theory is used to analyze the state and control the working process of the ventilator control system. According to the operating conditions of theventilator, the control circuit is divided into different working states. These working states are combined into a specific limited state machine to realize the control and state transfer of the VFD, Thus, the reliability of ventilator control system can be improved.
