Abstract

The invention discloses an ultra-high precision oblique test platform and relates to the oblique test technology of a geoscientific instrument. The platform comprises a PC controller, a first grating ruler measuring mechanism, a second grating ruler measuring mechanism, a first base, a second base, a first force balancing device, a second force balancing device, a third grating ruler measuring mechanism, a linear motor drive mechanism, a platform panel, a positioning base and a third balancing device; the PC controller is respectively connected with the linear motor drive mechanism, the first grating ruler measuring mechanism, the second grating ruler measuring mechanism, the first base and the third grating ruler measuring mechanism, and not only is used for acquiring probe displacement signals from the first grating ruler measuring mechanism, the second grating ruler measuring mechanism and the third grating ruler measuring mechanism, but also is used for controlling the stepping motor motion of the linear motor drive mechanism, the first base and the second base. The ultra-high precision oblique test platform disclosed by the invention is applicable to oblique platform test and finishes the detection and calibration works of the instrument.

Description

technical field [0001] The invention relates to an inclination testing technology of geoscience instruments, in particular to an ultra-high-precision inclination testing platform. Background technique [0002] In the field of geophysical observation instruments, the tiltmeter can measure in one direction (1D) or in two directions (2D) simultaneously. According to the existing standards, the index of each direction is a maximum error of 0.003 arc seconds, a range of 2 arc seconds, and a discrimination of 0.0002 arc seconds. It is difficult to trace the source with the existing tilting platform testing technology, and the detection and calibration of the instrument cannot be well completed. [0003] The tilt instrument placed on the surface of the positioning base measures the response of the tilt displacement, velocity, and acceleration of the crustal surface; when the tilt instrument is placed on the tilt platform, and the tilt platform is placed on the surface of the posit...
