Description
Technical Field
This paper relates to inclination measuring equipment technical field, concretely relates to inclination information measuring device.
Background
In the installation, test and even operation stages of a plurality of devices, the inclination angle measuring device is used for measuring and correcting the installation angle of the devices, and can also be used as an inclination angle sensor, so that the application is very wide. Although the existing inclination angle measuring devices are various, the existing inclination angle measuring devices have high measuring precision, high price, large volume and weight, difficult carrying and inconvenience for use at any time in any environment; the volume is medium, the portable and the measuring precision can not be ensured.
In order to solve the above problems, the prior art adopts a PSD position sensor and a three-dimensional tilt angle sensor, which includes a spherical shell, wherein a plurality of PIN photodiodes are uniformly distributed on the inner surface and/or outer surface of the shell to form a position sensitive detector of a two-dimensional spherical surface, a transparent spherical shell is arranged on the outer layer of the spherical shell, a gap between the spherical shell and the spherical shell is filled with opaque liquid, and a bubble capable of making external light irradiate on the PSD position sensor shell is formed on the top of the liquid. This prior art structure is comparatively simple, and it is convenient to detect, but still has following problem in manufacturing and use: 1. the sensor realizes the determination of three-dimensional position information by depending on the movement of bubbles in opaque liquid, except that the movement sensitivity of the bubbles is influenced by the viscosity of the liquid, the movement sensitivity of the bubbles is reduced when the viscosity of the liquid is increased, the volume of the bubbles is also influenced by the surface tension of the liquid, the larger the surface tension of the liquid is, the larger the volume of the bubbles is, the viscosity and the surface tension of the liquid are easily influenced by the environmental temperature to change, so that the movement sensitivity of the bubbles and the volume of the bubbles change along with the environmental temperature, the measurement results of the sensor under different environmental temperatures are inconsistent, and particularly under extreme environments, the measurement accuracy is difficult to ensure; moreover, because the bubbles are always positioned at the top, the bubbles can not fill the gap between the spherical shell and the spherical shell due to the reduction of the volume of the bubbles, so that the bubbles and the outer surface of the spherical shell are filled with opaque liquid, and the light penetrating through the bubbles is prevented from further irradiating the PIN photodiode of the spherical shell, so that the sensor cannot be used; 2. the sensor is almost filled with opaque liquid, but the sensor which is simple in structure and light in weight originally has the advantages that the self weight is increased due to the filling of the liquid, and the sensor is easy to leak the liquid when damaged and broken, so that the environment is polluted, the cleaning is difficult and the repairing is difficult; 3. the sensor needs to process two spherical shells which are nested inside and outside, the PIN photodiode is arranged on the surface of the spherical shell inside, the processing difficulty is high, the cost is high, the transparent spherical shell is difficult to give consideration to hardness and light weight, and the requirement on the control precision of the bubble volume is high.
