AI Technical Summary

Problems solved by technology

At the same time, because the construction, equipment and operation and production activities of the subway are all underground, and there are a large number of electromechanical equipment and a certain amount of flammable and combustible substances, there are many passengers and staff during the operation, and the structure of the subway station is not good. It is conducive to the escape of personnel, so once a fire breaks out in a subway station, it will cause huge casualties and property losses

Moreover, once a fire breaks out in a subway station, the underground smoke will spread rapidly, and spread upward through the stairs and internal patios, affecting evacuation.
