Positive pressure ventilation safety control system and method for anti-explosion control room

According to the positive-pressure ventilation safety control system and method for the anti-explosion control room, the ventilation safety system is arranged in the anti-explosion building, when leakage or explosion accidents occur outdoors of the anti-explosion building, a fresh air source entering a room is stopped or blocked, at the moment, an indoor all-air air conditioning system can still operate normally, and the safety of the anti-explosion building is guaranteed. When the outdoor risk is not eliminated for a period of time, the system can adjust the indoor oxygen concentration in time, control the safety index according to the toxic combustible gas detector, optimize the ventilation control conditions from different angles and states, and improve the safety and reliability of the system. Emergency supply of fresh air in an accident state is improved, and health and safety of internal personnel on duty are guaranteed. 本发明提出了一种抗爆控制室正压通风安全控制系统及方法，将通风安全系统设置在抗爆建筑物内，当抗爆建筑物室外发生泄漏或爆炸事故，进入室内的新风气源被停用或阻断，此时室内全
