Embodiment

Embodiment 1

Contrast Fig. 1, Fig. 2 vertical rotation support 5 are connected with the axle 15 of housing 3 centers by bearing 14, can do on the horizontal plane direction clockwise or rotate counterclockwise around axle 15, and the about 355 ° of degree of rotation angle rotate by synchronous machine 2 drives.

Synchronous machine 2 is fixed on the vertical rotation support 1, on its rotatingshaft 18 gear 17 is housed, and gear 17 and gear 13 engagements form another gear pair 19.Gear 13 is fixed on the axle 15, do not rotate with respect to axle 15, so when gear 17 follows that synchronous machine 2 rotates and during with gear 13 engagements, gear 17 revolves round the sun around gear 13 again except rotation simultaneously, drive vertical rotation support 5 with this and rotate, so gear 13, gear 17 and vertical rotation support 1 constitute a planet gear drive.

The one end axle and the housing 3 of gear 11 are hinged, and be installed in gear 16 engagements of axle on 15, potentiometer 9 is installed on the gear 11, its adjusting axle 10 is connected with the other end axle of gear 11, potentiometer 9 Standard resistance ranges 0～5k Ω, when vertical rotation support 1 rotates, gear 10 is except that also produce rotation simultaneously around the revolution of vertical rotation support 1 center thereupon, and the adjusting axle that drives potentiometer 9 rotates, output resistance on each pivotal position of the adjusting axle of potentiometer 2 is all different like this, the current potential Vy of its output terminal y also changes thereupon, so vertical rotation support 1 is each rotation angle θ on horizontal plane, all have a Vy value corresponding with it, each Vy value all is input to the analog amount input end of decode controller 8.

The rotatingshaft that horizontally rotates support 5 two ends that are placed in one heart, the axle of one end and synchronous machine 4 is connected, and the adjusting axle 6 of the other end and potentiometer 7 is connected, and potentiometer 7 is installed on the vertical rotation support 5, and its Standard resistance range also is 0～5k Ω.Synchronous machine 4 is fixed on the vertical rotation support 1, and its drive horizontally rotates support 5 and rotates about 90 ° around horizontal axis in vertical plane.The same reason, horizontally rotate support 5 each rotation angle φ on vertical surface, the adjusting axle of its potentiometer 7 rotates an angle synchronously, and an output resistance is arranged on its x position, and the output potential Vx of corresponding with it x end is input to the analog amount input end of decoding control circuit 8.

The angle of swinging mounting 5 rotation spatially that above-mentioned like this two swinging mounting rotation angle value θ and φ have made up final decision.This mechanical rotation amount is transformed into electrical signal by described potentiometer and is input in the decoding control apparatus 8, and decode controller just can be according to the The Cloud Terrace location parameter that sets in advance like this, and the position signal of relatively constantly importing one by one decides the rotation and the locking of The Cloud Terrace.
