[0052] The wind speed and direction monitoring module can obtain the wind speed, wind force and wind direction outside the elevated subway station in real time. When encountering extreme weather such as typhoons or severe convection, the station EMCS module controls the windproof facilities to keep the elevated subway station hall in a closed state, avoiding damage to the hall caused by extreme weather and protecting the safety of staff. The station IBP module controls the safety equipment to issue an alarm to remind staff of abnormal external weather conditions, and sends a stop operation command to the train in the track area to implement the train detention operation, protect the safety of the train, and avoid danger to the train in extreme weather.

[0053] In addition, by automatically controlling the lowering of electric rolling shutters, the closing of electrically adjustable exterior windows, and the power off of advertising light boxes in the track area, the wind direction that is manually operated in extreme weather is avoided, thereby improving the on-site wind protection efficiency.
