The invention relates to the technical field of intelligent buildings, in particular to an intelligent building window management system based on the Internet of things. The intelligent building window management system based on the Internet of things comprises a plurality of supporting columns arranged between floor slabs and ceilings, and a french window is formed among the floor slabs, the ceilings and two supporting columns. Glass brackets are arranged on the inner side of the french window, the glass brackets are composed of a plurality of transverse rods and vertical rods, and the transverse rods and vertical rods are arranged in a staggered mode. Windows are installed in part of the glass brackets, the windows comprise round rods arranged at the upper ends of the windows, and firstrotating shafts are connected to both ends of the round rods. Shaft holes connected with the first rotating shafts in a matched mode are formed in the vertical rods, first cavities are formed in the round rods, and clamping mechanisms for limiting the rotation of the round rods are installed in the first cavities. The intelligent building window management system based on the Internet of things has the advantages that based on the combination of the intelligent building window management system and the Internet of things, the remote and automatic control of the building window is further realized, and at the same time, the window management system has low construction cost, attractive appearance and high integration degree.
