| description | The utility model provides a speed measuring device by utilization of optical fiber transmission, and belongs to the speed measuring device technology field. The speed measuring device comprises a code disc, a code disc rotating shaft, a light emitting tube, a photoelectric receiving tube, optical fibers and a signal processing circuit. The code disc rotating shaft is connected with a shaft of a roller to be measured. The light emitting tube and the photoelectric receiving tube are connected with the signal processing circuit. The light emitted by the light emitting tube is transmitted to one side of the code disc through the sending transmission optical fiber, and is transmitted to the photoelectric receiving tube through the receiving transmission optical fiber at the other side, and conversion from an optical pulse to an electric pulse is achieved through the signal processing circuit. The speed measuring device employs optical fiber transmission and a power supply is not needed in a detection section, so the explosion protection problem does not exist. Signal transmission employs optical signals and the electromagnetic interference problem does not exist. |
