Example Embodiment

[0025] The inventive idea of ​​the present invention is: a dynamic balance control device for a telephoto system of optical measurement equipment. The dynamic balance control device is installed by a fixed frame under the lens barrel of the main environment of the optical measurement equipment telephoto system. There are:

[0026] A long-shaped cam curve groove with a linear displacement sensor and a cam; a slider that can slide along the cam curve groove with the action of the cam; a driving nail that can drive the slider to slide; and an electronic control system;

[0027] The linear displacement sensor can feed back the position information to the electronic control system through the input and output signal interface according to the position of the slider; the electronic control system can compare the received position information with the focal length value, if the error is not zero , The stepping motor is driven to drive the cam action, and the position of the slider is adju...

Abstract

The invention relates to a dynamic balance control device for a telescopic system of optical measurement equipment. The dynamic balance control device is arranged below a tube of a primary mirror in the telescopic system of the optical measurement equipment by a fixing frame on which a long strip-shaped cam curved groove, a slide block capable of sliding along the cam curved groove, a driving screw capable of driving the slide block to slide and an electric control system are arranged, wherein a linear displacement sensor and a cam are arranged on the cam curved groove; the linear displacement sensor can feed back the position information of the slide block to the electric control system through an input-output signal interface according to the position of the slide block; and the electric control system compares the received position information with the focus value, drives a stepping motor to drive the cam to move if the error is not zero so as to adjust the position of the slide block till the error is approximate to zero and the equipment stays in a balance state. The dynamic balance control device provided by the invention automatically adjusts the counterweight slide block according to the focus value to achieve the purpose of automatic counterbalancing, and has the characteristics of real-time adjustment, compact structure, stability in work and convenience in use.

Description

technical field [0001] The invention relates to the technical field of optical measuring equipment, in particular to a dynamic balance control device for a telescopic system of optical measuring equipment. Background technique [0002] Optical measurement equipment mainly refers to the special measurement system that collects flight target information by the principle of optical imaging, obtains the required ballistic parameters and target characteristic parameters after processing, and obtains image data. It is widely used in modern shooting ranges. Before the optical measurement equipment is officially used, the overall weight of the equipment should be carried out so as to keep the equipment stable during the process of tracking the target. The equipment is counterweighted under a certain stable condition (such as the focal length is fixed at 600mm or 2400mm), and the counterweight will not change after the counterweight is completed. When the focal length is from 600mm ...
