Electromagnetic braille reader, control system and application method

Abstract

The invention relates to an electromagnetic braille reader comprising a reading plate; a display region is arranged on the reading plate, a display groove is formed in the display region, a pluralityof display frames distributed in a matrix mode are arranged in the display groove, and the upper ends of the display frames are flush; six display contacts are arranged in the display frame, and the display contact comprises a magnetic cylinder and an electromagnetic coil sleeved outside the magnetic cylinder; the electromagnetic coil is fixedly connected with the bottom of the display frame, andthe magnetic cylinder is longitudinally and movably arranged in the electromagnetic coil; a movable door for shielding the display groove is further arranged on the display region, the movable door comprises a frame body connected with the reading plate in a rotating mode, and an elastic thin film is arranged in the frame body; annular iron rings corresponding to the display frames in a one-to-onemode are arranged on the inner side surface of the elastic thin film, the annular iron rings are matched with the display frames in shape, and a plurality of magnetic columns and containing holes forinstalling the magnetic columns are distributed on the upper end surface of the display frame in a surrounding mode. According to the electromagnetic braille reader in the invention, not only displaycan be performed in batches, but also the content is easy to change, the display content is rich, and great convenience is brought for maintenance.
