Automatic Control System of Local Fan in Underground Roadway
In order to improve the reliability of the ventilation system and the automatic control level of the local fan,the automatic control system of the local fan was constructed by using the fuzzy PID control algorithm.According to the construction goal of the automatic control system of local fan,the overall scheme of the system was given,the model of the system hardware equipment was selected and the control software was designed;the automatic control system adjusted the air supply by comprehensively analyzing the changes of gas and CO concentration in the roadway,and improves the ventilation safety guarantee ability on the basis of meeting the air demand of the roadway;the fault warning of local fan was realized by analyzing vibration and temperature parameters;it had the functions of remote one-click reverse,one-click start and stop,etc.,and at the same time,the local fan operation parameters and the environment parameters of the excavation roadway can be displayed in real time on the HMI platform.The application practice in 3306 transportation roadway shows that the local fan automatic control system was stable and reliable,and had a remarkable effect on improving the ventilation efficiency and the level of ventilation automation.
