Plummet multi-point 3D shift testing system and test data processing method thereof

Abstract

The invention relates to a plummet multi-point 3D shift testing system. The system comprises a plummet suspension device installed at a highest point of a to-be-tested building, a plummet suspended onthe plummet suspension device, and a heavy hammer damping device connected at the bottom of the plummet, wherein multiple shifting reading devices not contacting the plummet are arranged on the plummet, the multiple shifting reading devices are fixed at different heights of measurement points of the to-be-tested building through respective installation racks, and each shifting reading device comprises a horizontal shifting reading device and a vertical shifting reading device. The testing system realizes horizontal and vertical shifting simultaneous monitoring of multiple measurement points at different heights in the same direction, thereby reducing system installation amount, effectively lowering monitoring cost and saving space. A method of processing test data of the plummet multi-point 3D shift testing system can acquire 3D shifting values of measurement points at different heights in a certain direction of a to-be-tested building, and reduces system errors effectively through reading among multiple points.

Description

technical field [0001] The invention relates to the technical field of structural monitoring in civil engineering, in particular to a multi-point three-dimensional displacement testing system of a plumb line and a testing data processing method thereof. Background technique [0002] In the prior art, the plumb line vertical displacement test systems applied to the containment structure of nuclear power plants or other large structures are all single-point measurement systems, and the horizontal displacement test system and the vertical displacement test system are separated from each other. [0003] When measuring different elevations in a certain orientation of a large building structure, the existing measuring device needs to be provided with a set of horizontal testing systems and a set of vertical testing systems at different elevations in a certain orientation. The reading devices in the plumb line horizontal displacement test system are set at the bottom of the plumb l...

AI Technical Summary

Problems solved by technology

The reading device in the plumb line vertical displacement test system is set at the bottom of the plumb line protection tube, and the vernier caliper is used for manual reading. Therefore, a plumb line vertical displacement monitoring system can only measure one position and one level. A measuring point for vertical displacement monitoring

[0004] It can be seen that the above-mentioned existing measuring devices are not only complex in system, occupy a large space, but also have a single measurement and reading
