Dynamic balance control device for telescopic system of optical measurement equipment

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 performs counterweight 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 60...

AI Technical Summary

Problems solved by technology

When the focal length is from 600mm to 2400mm, the zoom assembly moves from end A to end B along the axis of the main mirror, and there is a weight difference of about 10 catties between the front and rear of the axis, which makes the equipment counterweight unbalanced and affects tracking
