Operation and maintenance monitoring, regulation and control management system for traffic tunnel

The invention discloses an operation and maintenance monitoring, regulation and control management system for a traffic tunnel, and particularly relates to the field of tunnel supervision, which is used for solving the problems of operation and maintenance supervision and disaster disposal of the traffic tunnel and comprises the following steps of: calculating a tail gas concentration gradient, an operation abnormal index and a ventilation efficiency abnormal score of each equipment from the actual working effect of ventilation equipment; the ventilation efficiency and the equipment performance in the tunnel are effectively monitored and evaluated, the low-efficiency or abnormal ventilation equipment is recognized in time, and it is ensured that the air quality meets the safety standard. In addition, by analyzing the length of the channel, the number of detained vehicles and the ventilation efficiency, the optimal smoke exhaust channel is determined, the smoke exhaust speed is increased, and the evacuation ef
