Abstract

The invention discloses a U-disc alarm device for a classroom multimedia platform. The device comprises a radio pulse emission module, a radio pulse reception module, a range finding module, an alarmdistance determining module, a buzzing alarm module and a power supply module; and the range finding module calculates distance from the radio pulse emission module to the pulse reflection surface byusing characteristic of a pulse signal emitted by the radio pulse emission module and characteristic of a pulse signal received by the radio pulse reception module. During use, when the multimedia platform is closed by a push-and-pull cover after a class, the push-and-pull cover serves as the pulse reflection surface, the measured distance equals distance from the horizontal plane where a U-disk jack of the multimedia platform is positioned to the horizontal plane where the push-and-pull cover in the top of the multimedia platform is positioned, the alarm distance determining module can determine the platform closing and class ending state, and the buzzing alarm module raises alarm by buzzing. Problems in the prior art are solved, and the device of the invention is high in versatility andlow in false alarm probability.
