Abstract

The invention discloses a switching control method of a dual-view-field optical lens, and belongs to the technical field of control. The switching control method is achieved by a controller provided with a switch control software package. After the controller is powered on, the controller enters a corresponding control flow cycle according to a switching command; when a high level signal is detected by a Hall switching device, the controller controls a zoom lens to move towards the direction close to a switching position; when a low level signal is detected by the Hall switching device, the controller controls the zoom lens to move towards the direction away from the switching position. During the initial switching period, the controller controls the zoom lens to continuously move towards the direction close to the switching position, the zoom lens conducts tender motion at the switching position, the fact that the zoom lens is always in a controlled state is ensured, and the zoom lens has the capacity of real-time protection against external disturbances. The switching control method of the dual-view-field optical lens has the advantages of being high in control precision, simple, easy to implement and the like.

Description

technical field [0001] The invention belongs to the technical field of control, and mainly relates to a switching control method of a dual-view field optical lens, in particular to an anti-disturbance switching control method of a dual-view field optical lens with a zoom mirror moving along an optical axis. Background technique [0002] Dual-field optical lenses are widely used in reconnaissance and tracking integrated optoelectronic systems. The large-field optical lens is used for large-scale reconnaissance and detection of the battlefield environment. Once a sensitive target is found, the small-field optical lens will be quickly switched to The optical path is used for stable aiming and tracking of maneuvering targets, and provides target indication for precision strike weapons. [0003] A dual-field optical lens with a zoom lens that moves along the optical axis. When the zoom lens moves to the short-focus position along the axis, it will form a clear image with a large ...
