Parameter calibration method and parameter calibration device

The invention relates to a parameter calibration method and a parameter calibration device. The method comprises the following steps: acquiring an acceleration component of a gravity acceleration on each coordinate axis of a triaxial acceleration sensor, wherein the acceleration components are gravity acceleration components collected by the triaxial acceleration transducer under a static condition; calculating a deflection angle of a detection axis of the triaxial acceleration transducer relative to a detection axis in a running coordinate system of an object according to the gravity acceleration components; and calibrating motion parameters, which are collected by a target sensor, on a detection axis of the target sensor according to the deflection angle, wherein the target sensor is arranged on the object, and comprises the triaxial acceleration sensor and/or other sensors with detection axes parallel to that of the triaxial acceleration sensor. After the parameter calibration method and the parameter calibration device are applied, the target sensor is not required to be horizontally arranged, so that installation time is saved, the installation efficiency is improved, and the defect of inaccurate measured data caused by horizontal deviation of installation is avoided.

Splicing, mounting and fixing machine of LCD liquid crystal spliced screen, and mounting method

The invention relates to a splicing, mounting and fixing machine and a mounting method of an LCD (liquid crystal display) spliced screen. The splicing, mounting and fixing machine comprises an outer frame, a skeleton, mounting frames, fixing devices and limiting rods; the skeleton is arranged in the outer frame, the limiting rods are arranged at a front end of the skeleton, and the mounting framesare uniformly arranged at the rear end of the skeleton; and the fixing devices are symmetrically arranged at an upper end and a lower end of each mounting frame. The problems that the holes cannot bealigned since a single spliced screen needs to be pressed in the skeleton to prevent the spliced screen from falling off when the spliced screens are connected through bolts, a certain gap is existent between the spliced screen and the skeleton frame, and the spliced screen is likely to displace in the manual pressing, the mounting time of the single spliced screen is longer since the spliced screens can be aligned and mounted by continuously adjusting the positions of the spliced screens by the personnel, and the single person is hard to quickly accomplish the operation since the personnelneeds to perform bolt connection while pressing the spliced screen are solved.
