The invention provides a vertical storage tank safety system, comprising a target set at least including a reference target set; a total station measuring unit used for measuring the reference coordinates of targets in the reference target set; a three dimensional laser scanning unit used for scanning a surface of the storage tank to be scanned and the reference target so as to obtain the storage tank point cloud data on the surface of the storage tank to be scanned, and the target point cloud data of targets in the target set, and sending the data to a data processing unit; and the data processing unit used for generating the deformation data of the storage tank to be detected according to the reference coordinates, storage tank point cloud data and target point cloud data. The vertical storage tank safety system can obtain storage tank geometrical deformation details in a relatively comprehensive way.

Description

technical field [0001] The invention relates to the technical field of storage tank safety management and monitoring, in particular to a vertical storage tank safety system. Background technique [0002] With the wide application of vertical storage tanks, the safety of vertical storage tanks has been paid more and more attention. The stress distribution and deformation of the bottom and wall of vertical storage tanks are very complex, so vertical storage tanks, especially large vertical storage tanks, have high requirements for the bearing capacity, stability and post-construction settlement of the foundation. There are many factors that affect the safe operation of vertical storage tanks. Among them, the geometric dimensions of the tank body, such as local unevenness, ellipticity, and maximum inclination, are very important indicators. If these indicators are too large and exceed a certain limit, the storage tank will fail due to stress concentration. It cannot be fully u...

AI Technical Summary

Problems solved by technology

The optical reference method requires the use of optical plummets, horizontal rulers, mobile magnetic rulers, etc., but if the deformation of the tank wall is more complex, this method will produce large measurement errors

The photoelectric method to measure the deformation of the storage tank usually uses a total station and GPS (Global Positioning System, Global Positioning System) to measure the key points of the storage tank at a single point, that is, to obtain part of the observation point data by means of point observation to indirectly calculate and infer the storage capacity. The geometric deformation data of the tank, so the local and overall geometric deformation details of the storage tank cannot be obtained, and the equipment installation of this method is difficult, which cannot meet the actual production needs

[0004] It can be seen from the above description that the existing technology cannot fully obtain the geometric deformation details of the storage tank
