Abstract

The invention discloses a laser optical disc-based digital inclined-angle sensor. The laser optical disc-based digital inclined-angle sensor comprises a housing, a fixing seat, two laser head assemblies and a turnplate, wherein the two laser head assemblies and the turnplate are arranged in the housing. The fixing seat is fixed on an upper of the housing. A circuit board is arranged in the fixing seat. The circuit board is provided with a microprocessor. The two laser head assemblies are connected to the microprocessor by two circuits. The two laser head assemblies are located below the fixing seat. The turnplate is located below the two laser head assemblies. The turnplate is fixed in the housing by a rotation shaft. The turnplate is provided with a pendulum bob. The periphery of the turnplate is provided with a round of reflector panels. Tops of the reflector panels are located behind the two laser head assemblies. The reflector panels are provided with multiple nicks. The laser optical disc-based digital inclined-angle sensor has the advantages of high resolution ratio, high precision, stable and reliable performances, good linearity, high signal-noise ratio, low influence caused by a temperature change, wide measuring range (360 degree), simple structure and low cost.

Description

technical field [0001] The invention relates to a digital tilt angle sensor based on a laser disc. Background technique [0002] Sensor technology has always been a hot technology in the scientific research community. The tilt angle sensor is a sensor used to measure the tilt angle, and is widely used in factories, railways, ships, machinery, construction, bridge laying, dam construction, automobile industry, etc. Among the traditional inclination sensors, the solid pendulum inclination sensor is a common category and widely used. This type of inclination angle sensor is generally composed of a pendulum and a displacement sensor. The displacement sensor includes: capacitive, inductive, eddy current, resistive, etc.; most displacement sensors are analog outputs, which need to be passed through A / D can only be input into the computer system after it is converted into a digital quantity. The relationship between the original electrical output of the displacement sensor and ...
