At present, the positions of the openings such as the exit, the wind pavilion, the evacuation channel, the tunnel portal and the like designed for the subway line network and the external environment are all provided with communicating openings. In heavy rain, manual inspection needs to be performed to confirm whether the water level is normal. At present, water level monitoring and alarming are not arranged outside the positions of the entrances and exits, the wind pavilions, the evacuation channels, the tunnel portals and other mouths of the subway line network, the water level of the exterior rises due to heavy rain for a plurality of times, and meanwhile, the water level of the positions of the entrances and exits, the wind pavilions, the evacuation channels, the tunnel portals and other mouths of the subway line network rises to further influence the conditions of stations and regions, so that potential safety hazards are brought to passenger service and driving. The reason is that the number of the positions of the entrances, the exits, the shelters, the evacuation channels, the tunnel portals and other openings is large, the distribution is wide, and no corresponding alarm display is provided when the external water level is abnormal. If the water level outside the entrance position such as the entrance, the wind pavilion, the evacuation passage, the tunnel portal rises, and once the water level of the entrance, the wind pavilion, the evacuation passage, the tunnel portal and other entrance positions rises to a dangerous water level, great safety risk is brought to station passenger service and driving due to long manual inspection time and incapability of timely confirmation.
