Inclination tester and test method based on spherical cavity mercury reflection

Abstract

The present invention relates to the technical field of angle detection, in particular to an inclination tester and a test method based on mercury reflection in a spherical cavity. The tester includes a signal acquisition module, a signal conditioning module and a control module; the signal acquisition module includes a shell and is arranged in the shell The test ball includes an inner spherical surface, an outer spherical surface, a first fixed axis and a second fixed axis, the inner spherical surface and the outer spherical surface are arranged concentrically, and the outer wall of the inner spherical surface is provided with an optical transceiver, and each optical transceiver includes a light emitting diode and a photosensitive tube for lighting; the outer wall of the inner spherical surface and the inner wall of the outer spherical surface are painted with black light-absorbing materials; a gap cavity is formed between the inner spherical surface and the outer spherical surface, and mercury is injected into the lower part of the gap cavity, and the mercury surface points to the center of the sphere. The circumscribed circles of the area where the optical transceiver is located are parallel and of the same size; the signal conditioning module is used for signal conditioning of the electrical signal converted from the optical signal collected by the photosensitive tube; the control module is used for tilt angle calculation. The invention realizes the calculation and detection of the inclination angle.

Description
