Benefits of technology

This patented technology allows for accurate measurements over small spaces without complicated equipment or requiring expensive tools like optical sensors. It uses a special type of machine called a digital microscope to measure tiny changes caused by rotation about its axis during operation. By analyzing these minute movements it becomes possible to determine how well things have been done before they were last updated. Overall this innovation makes it easier and more efficient than current methods such as laser interferometry.

Problems solved by technology

Technological Problem: Current systems used for measuring angle displacements involve manually counting scale measurements on paper during calibration procedures after each usage period (usually 2-3 hours). However these techniques may result in incorrect data due to human error such as eye fatigue from prolonged visual inspections.

Abstract

The invention discloses an embedded angular displacement online measurement method and device; a dial is arranged on a measured workpiece and can rotate by a corresponding angle along with the measured workpiece; a displacement sensor is arranged on the dial, and the dial rotates by a certain angle along with the rotation of the measured workpiece; a displacement sensor mounted on the dial outputs a series of pulse signals, and the magnitude of the rotation angular displacement can be calculated by carrying out noise reduction and pulse counting on the pulse signals. The device is simple in structure, convenient to install, high in testing precision and capable of achieving on-line measurement of angular displacement in a narrow space.
