The utility model discloses an anti-falling wind-resistant intelligent building external sunshade venetian blind. The system comprises a sunshade venetian blind, an outdoor meteorological data detection device used for collecting meteorological data such as outdoor wind speed, an indoor environmental parameter detection device used for collecting environmental parameters such as indoor illuminance, and a sunshade controller used for controlling the movement of the venetian blind according to the outdoor wind speed or indoor designed brightness. The outdoor meteorological data detection deviceor the indoor environment parameter detection device collects the outdoor wind speed or the indoor design brightness and transmits the wind speed or the design brightness parameter to the sun-shadingcontroller, and the sun-shading controller adjusts the working state of the sun-shading shutter blind according to the preset wind speed parameter or the preset design brightness. The anti-falling device can solve the problem of safe falling to the maximum extent when strong wind, sea area working conditions or earthquakes happen.
