Curtain wall structure sealing performance detection system and detection method

The invention relates to a curtain wall structure sealing performance detection system and detection method. The system comprises a single-chip microcomputer installed in a closed cavity; the air pressure sensor is mounted in the closed cavity, is connected with the single chip microcomputer and is used for detecting an actual pressure value P in the closed cavity; the judgment unit is connected with each single chip microcomputer, is positioned outside the closed cavity, and is used for analyzing the actual data of the actual pressure value P of each closed cavity and judging whether the leakproofness of each closed cavity is invalid or not; and the display unit is connected with the judgment unit, is positioned outside the closed cavities, and is used for displaying the judgment result of the leakproofness of each closed cavity. According to the invention, real-time detection is carried out on the joint of each curtain wall plate, the position of sealing failure on the curtain wall structure can be position
