The invention discloses a speed measuring device and a speed measuring method, which belong to the field of speed measurement. The speed measuring device includes a base, a metal sensor, a rope coiling wheel, a non-metallic rope, and a plurality of metal rings; the metal sensor and the rope coiling wheel are separately disposed on the same surface of the base, the metal sensor is provided with a first through hole, and an axis of the first through hole and the axis of the rope coiling wheel are located on the same plane and perpendicular to each other; and the plurality of metal rings are spaced apart from each other on the non-metallic rope in an extending direction of the non-metallic rope, a first end of the non-metallic rope is wound on the rope coiling wheel, and a second end of the non-metallic rope passes through the first through hole and then is used for connecting a speed measuring object. A whole process of the speed measuring device and the speed measuring method does not require the speed measuri
