Embodiment Construction

[0034] Include the following steps:

[0035] (1) Install either the transmitting end device or the receiving end device in a stable position. If the position is unstable, an absolute displacement measuring device for the end point must be installed;

[0036] (2) Install a measuring point box for displacement correction of the other end point within 5-20m from the end point. The measuring point box and the end point equipment are required to be installed on the same platform or ensure that the position of the calibration device is accompanied by the end point Simultaneous deformation;

[0037] (3) Calculate the relative displacement change between the receiving end and the transmitting end by measuring the displacement change of the position of the measuring point box, and calculate the relative displacement change between the receiving end and the transmitting end through the end point correction calculation method. The relative displacement change plus the absolute displaceme...

Abstract

The invention relates to a method for correcting the absolute displacement of an end point of a vacuum laser alignment displacement measurement device, which belongs to the improvement of a building displacement monitoring method. Install any one of the transmitting end device or the receiving end device in a stable position, and install a measuring point box for displacement correction of the other end point within 5-20m from the point end, by measuring the position of the measuring point box The relative displacement change of the receiving end and the transmitting end is calculated by the endpoint correction calculation method, and the relative displacement change plus the absolute displacement of the endpoint is the absolute displacement change of the other endpoint. The advantage is that because only one measuring point is added, the measuring time basically does not change much compared with other schemes, which not only meets the requirements of system layout, but also greatly saves engineering investment.

Description

technical field [0001] The invention belongs to the improvement of a building displacement monitoring method. Background technique [0002] The vacuum laser alignment displacement measurement device has been widely used in the displacement monitoring of linear buildings, which can measure the displacement changes in the horizontal X direction (perpendicular to the axis of the building) and the vertical Z direction. The system is mainly composed of laser emitting device, laser receiving device, measuring point box, vacuum pipeline, vacuum control system and data acquisition system. The system principle and composition are detailed in "Vacuum Laser Alignment Displacement Measuring Device" (DL / T328-2010). [0003] The vacuum laser alignment displacement measurement device measures the relative displacement change of the measuring point relative to the transmitting end (where the laser emitting device is located) and the receiving end (where the laser receiving device is locate...
