Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0038] refer to figure 1 , a high-precision screw drive fixed-point passive mapping follow-up tracking focusing system, including: a traverse track 1, a structure used to move on it, track brackets are installed at both ends of the traverse track 1, and the track brackets are erected on On the ground, keep the traverse track 1 stable.

[0039] The pan-tilt 2 is used to carry the tracking and adjusting mechanism. The pan-tilt 2 is rollingly connected to the traversing track 1 through the drive wheel 34 , and the pan-tilt 2 carries the tracking and adjusting mechanism to move on the traversing track 1 .

[0040] refer to figure 2, orienting mechanism 3, is used to c...

Abstract

The invention discloses a high-precision screw drive fixed-point passive mapping follow-up tracking focusing system and method, which relate to the technical field of tracking and positioning, including a traverse track, a structure for carrying on the movement thereon, and two ends of the traverse track A track bracket is installed, wherein the track bracket is erected on the ground; the pan-tilt is used to carry the tracking and adjustment mechanism, and the pan-tilt is connected to the traverse track through the moving wheel; the orientation mechanism is used to control the pan-tilt to point to the target point The angle of the tracking and adjusting mechanism changes when the pan-tilt moves along the traverse track to track the target point. The present invention is based on the miniature mapping relationship between the directional triangle and the miniature triangle and the ratio of the circumference of the driving wheel to the lead of the screw is equal to the miniaturization ratio. Make the directional rod and the focusing direction of the tracking mechanism correspond to the mapping relationship. Since the directional rod is still pointing to the main shaft, the focusing direction is still pointing to the target point through the mapping relationship, and the tracking and adjusting mechanism moving on the entire traversing track can complete the tracking of the target point. Directional tracking.

Description

technical field [0001] The invention relates to the technical field of tracking and positioning, in particular to a high-precision screw drive fixed-point passive mapping system and method for follow-up tracking and focusing. Background technique [0002] The horizontal track with tracking in the prior art usually actively adjusts the angle of the tracking mechanism through a mechanical mechanism when the target is tracked, so that the angle of the tracking mechanism is continuously adjusted when the tracking mechanism moves along the horizontal track to form Tracking effect on the tracked target. However, the tracking effect of this kind of mechanical active tracking device is poor. In the process of moving along the lateral track, it can only ensure that the tracking point is located near the target point. Tracking points for control and adjustment are available on locally limited tracks, and the tracking points for other tracks have large deviations; and in the prior art...
