When it rains or snows, the rain and snow sensors 9 first sense the rain or snow, the variable rail drive 7 acts to automatically switch the semi-active guide rail 6 to be communicated with the horizontal guide rail 4, and then the roller shutter door body 1 is lowered along the horizontal guide rail 4 to extend outward to provide rain protection or snow protection for passengers entering or leaving the station. When the rain or snow stops, the rain and snow sensors 9 above the subway station cannot sense the rain or snow, and the roller shutter door body 1 is automatically stored in the box cover 31. The variable rail drive 7 acts to automatically switch the semi-active guide rail 6 to be communicated with the vertical guide rail 5. During the closing period of the subway at night, the roller shutter door body 1 is lowered along the vertical guide rail 5 to achieve the purpose of closing and separating the inside and outside of the subway station.
