The invention discloses a cloud deck capable of measuring rotation angle per se. The cloud deck comprises a base, an outer shell, a vertical connecting shaft, a horizontal motor, a horizontal speed reducer, a horizontal worm, a horizontal worm wheel, a vertical transmission shaft, a vertical shaft coupler, a vertical bracket, a horizontal coder, a horizontal shaft coupler, a horizontal bracket, a vertical coder, a vertical worm wheel, a vertical worm, a vertical motor, a protective hood and a vertical speed reducer. As the horizontal coder is arranged on the vertical connecting shaft, the horizontal coder rotates around the vertical connecting shaft when the cloud deck rotates horizontally and reads the horizontal rotation angle of the cloud deck; as the vertical coder is arranged on the vertical transmission shaft, the vertical coder rotates around the vertical transmission shaft when the cloud deck rotates in the vertical direction and reads the vertical elevation angle of the cloud deck; influence from transmission abrasion of the worms and the worm wheels and processing error is avoided during the measurement of the rotation angle, and the cloud deck capable of measuring the rotation angle per se has the advantages of low cost, simple structure and high precision.
