Vertical storage tank deformation monitoring system and method

Abstract

The present invention relates to a vertical storage tank deformation monitoring system. The system comprises a data processing device, a positioning device, a total station installed at a first reference point, a reflecting prism installed at a second reference point, a three-dimensional laser scanner installed at each surveying point, and a plurality of scanning target sets located at the wall of the vertical storage tank and arranged corresponding to the surveying points. The surveying points are distributed around the outer side of the vertical storage tank, and the distance among the first reference point, the second reference point and the vertical storage tank is larger than the distance between the surveying points and the vertical storage tank. The vertical storage tank deformation monitoring system and method are configured to scan the vertical storage tank and perform corresponding data processing by using three-dimensional laser scanning to realize the continuous monitoring of the whole geometry deformation safety status of the vertical storage tank.

Description

technical field [0001] The invention relates to the technical field of storage tank safety management and measurement, in particular to a deformation safety monitoring system and method for a large vertical crude oil storage tank. Background technique [0002] Large vertical storage tanks have the advantages of saving steel, occupying less land, saving investment, and being easy to operate and manage. Developed countries have built and used large-scale storage tanks for nearly 30 years. With the needs of production and the implementation of my country's strategic oil reserve plan, large-scale vertical storage tanks have also developed rapidly in China in recent years. There are many factors that affect the safe operation of vertical storage tanks, and the large-scale storage tank makes the stress distribution and deformation of the tank bottom and pipe wall very complicated. Usually, the local unevenness, ovality, maximum inclination of the tank body, foundation settlement, ...

Problems solved by technology

This monitoring method requires a certain number of reflectors to be arranged around the fixed site, and to ensure that the reflectors are fixed throughout the monitoring process, and then use the reflectors to register the response forms of scanned files under different time series according to the reference target reflection center. However, due to the limitation of objective factors such as the application environment and space in actual measurement, it is difficult to ensure that the reflector is fixed or it is difficult to find a space where the reflector can be installed, which reduces the practicability of this method, so it cannot be applied to vertical Safety Monitoring of Geometric Deformation of Type Storage Tank
