s324: setting the outdoor temperature as T0, when the lighting module (21) runs, if T0 is more than TLmax, the lighting module (21) is completely unfolded, and the scale is adjusted to be 9; if T0 is less than TLmin, the lighting module (21) operates, and the anti-dazzle module (22) is closed and retracted; if the TLmin is less than or equal to T0 and less than or equal to TLmax, the lighting module (21) and the anti-dazzle module (22) both operate;

s325: at least 4 illuminance measuring points are uniformly distributed on the working surface at the indoor near-window position and the depth position, and when the lighting module (21) and the anti-glare module (22) run, the illuminance of each point is measured and counted. Setting the number of the illuminance at the measuring points to be Q1 when the illuminance is lower than 300lx, setting the number of the illuminance at the measuring points to be Q2 when the illuminance is higher than 2000lx, and if Q1 is larger than Q2, reducing the scale of the lighting module (21); if Q1 is less than Q2, the lighting module (21) is increased by a scale; until Q1= Q2, the sunshade member (1) maintains this state until the next hour;

s326: a glare controller is arranged on each station, when the lighting module (21) and the anti-glare module (22) both operate, people on the station feel glare and can click the control switch without comfort, and the lighting module (21) is increased by one scale and kept in the state until the next hour.
