Zusammenfassung: | The utility model belongs to the technical field of expressway data acquisition equipment, and particularly relates to a data transmission device which comprises a supporting column, a monitoring device used for monitoring is arranged at the upper end of the supporting column, and a motor used for transmission and an annular groove used for sliding of a transmission block are arranged at the position, at the monitoring device, of the supporting column. One end of the connecting frame is fixedly connected with the supporting column, the other end of the connecting frame is connected with the base through the connecting block, the position is transmitted through the motor at the side end of the connecting frame, and the motor drives the rectangular block to rotate through the transmission shaft so as to drive the supporting column to rotate, so that the supporting column is rotationally lowered, and the height of the monitoring equipment is reduced. Meanwhile, a motor used for transmission is arranged at the mo |
