Problems solved by technology

[0004] At present, some angular displacement measurement methods use manual reading scales to measure the size of the angular displacement. This method is prone to errors, including errors caused by artificial vision; and this method needs to wait until the machine stops. Fang Ke’s readings cannot be monitored in real time

Abstract

The invention discloses an embedded angular displacement on-line measurement method and device. The dial is arranged on the workpiece to be measured and can rotate with the corresponding angle with the workpiece to be measured. The dial is provided with a displacement sensor, and the dial follows the movement of the workpiece to be measured. Rotate and turn through a certain angle, the displacement sensor installed above the dial will output a series of pulse signals, and the noise reduction and pulse counting of the pulse signals can calculate the size of the rotation angle displacement. The invention has the advantages of simple structure, convenient installation and high testing precision, and can realize on-line measurement of angular displacement in a narrow space.

Description

technical field [0001] The invention belongs to the technical field of angular displacement measurement, and in particular relates to an embedded angular displacement online measurement method and device. Background technique [0002] Armored vehicles are various tracked or wheeled military vehicles with armor protection, and are a general term for armored military or police vehicles. Armored vehicles have a high degree of off-road maneuverability. In order to achieve combat purposes, frequent braking is often required. The operating temperature of the brakes is high and the brake pads will be worn, which will weaken the braking effect or even cause the brakes to fail, causing accidents. [0003] Angular displacement is a physical quantity that describes the position change when an object rotates. For armored vehicles, in order to know the wear state of the brake pads in real time and replace the brake pads in time to ensure the braking effect of the armored vehicle, the ang...
