The ventilation conditions are complicated,the ventilation route is long and the air leakage is large in long-distance driving roadway,so it is difficult to achieve efficient ventilation if the single air supply volume is always maintained.Therefore,based on the technology of frequency conversion control,PLC(Programmable Logic Controller)control and sensor monitoring,a kind of intelligent ventilation system for long-distance driving roadway was constructed,and the architecture,intelligent frequency conversion regulation mode and field application effect of the system were analyzed.Engineering practice showed that the application of intelligent ventilation system can realize real-time monitoring of parameters such as gas volume fraction,wind speed,temperature and dust mass concentration in the roadway,and automatically adjust the air supply volume according to the field ventilation needs,so as to realize on-demand ventilation,ventilation parameter monitoring and intelligent adjustment of ventilation volume in the long-distance driving roadway.The application of intelligent ventilation system in long-distance driving roadway can improve ventilation efficiency and reduce ventilation energy consumption to a certain extent.
