description The utility model discloses a rail transit passenger room double-stage-pressure double-fire-extinguishing-agent fire prevention and control system. A double-stage-pressure double-fire-extinguishing-agent driving device can sequentially output water mist with the pressure larger than a first pressure threshold value, water mist with the pressure smaller than a second pressure threshold value and a perfluorohexanone fire extinguishing agent. The spraying system is connected with the two-stage pressure double-fire-extinguishing-agent driving device (3) and is used for extinguishing fire in the rail transit passenger room; and the terminal display controller displays the fire alarm signal and carries out emergency start and emergency stop operation on the two-stage-pressure double-fire-extinguishing-agent driving device. The fire prevention and control system provided by the utility model has a redundancy function, and can reduce the probability of system failure. The system is suitable for fire prevention and co
