AI Technical Summary

Technical Problem

The existing 3D scanning radar structure has problems such as frequent movement and bending of key components, resulting in low product reliability and service life.

Method used

A pitch reflection 3D scanning radar is designed, and through the coordinated cooperation of the detection circuit, horizontal rotation mechanism, signal reflection mechanism and pitch rotation mechanism, three-dimensional scanning and measurement of the material surface from both horizontal and pitch directions is achieved. At the same time, the detection circuit is fixed as a whole on the horizontal rotation mechanism to avoid relative movement between the main control board and the high-frequency board and reduce cable losses.

Benefits of technology

Improves the reliability of 3D scanning radar, extends its service life, and enhances the stability and accuracy of the radar by reducing cable losses.

Abstract

Provided in the present application is a pitching-reflecting 3D scanning radar, which comprises a horizontal rotation mechanism, a measurement circuit, a signal reflection mechanism and a pitching rotation mechanism. The pitching rotation mechanism is provided on a first preset position of the horizontal rotation mechanism, the measurement circuit is fixed to a second preset position of the horizontal rotation mechanism, the signal reflection mechanism is fixed to a first mounting position of a rotation shaft portion, and the horizontal rotation mechanism is used for driving the measurement circuit, the signal reflection mechanism and the pitching rotation mechanism to perform a synchronous horizontal rotational motion. On one hand, the present application uses the measurement circuit, the horizontal rotation mechanism, the signal reflection mechanism and the pitching rotation mechanism to perform three-dimensional scanning measurement on materials; on the other hand, since the whole measurement circuit is fixed to the horizontal rotation mechanism, all the components of the measurement circuit perform a synchronous horizontal motion, even if there are cables connected between the components of the measurement circuit, the cables are completely not affected, thereby reducing cable losses, helping to improve the reliability of the 3D scanning radar and further prolonging the service life of the 3D scanning radar.
