Method and system for selecting monitoring points of large-span truss sensor and computer equipment

Abstract

The invention relates to a large-span truss sensor monitoring point selection method and system and computer equipment, and belongs to the technical field of building construction, and the selection method comprises the following steps: building a three-dimensional model according to a construction drawing; carrying out stress analysis on the three-dimensional model to obtain a force transmission path; identifying a node on the force transmission path, taking the node as a force transmission node, and identifying a structural rod piece on the force transmission node; whether the two ends of the structural rod piece are connected with the force transmission nodes or not is judged, and if yes, the structural rod piece serves as an important rod piece; extracting the important rod pieces one by one to form a simulation calculation model of the important rod pieces; carrying out collapse analysis on the simulation calculation model; and determining a monitoring object based on an analysis result, and setting a monitoring point of a sensor on the monitoring object. According to the method, the number and the positions of the monitoring points can be reasonably determined, and comprehensive and reliable monitoring of the construction process is achieved through a small number of monitoring points.

Description

technical field [0001] The present application relates to the technical field of building construction, and in particular, to a method, system and computer equipment for selecting monitoring points of large-span truss sensors. Background technique [0002] With the development of science and technology, structural health monitoring systems have been widely used to monitor the status of large-scale construction structures. Among them, the monitoring in the construction process is mainly divided into three processes: before the event, during the event, and after the event, and the prior monitoring is to strictly control the plan, using the organization, management and technical means of layer-by-layer approval and expert demonstration. [0003] At present, construction monitoring is mainly carried out by universities, hardware companies and software companies in relevant majors. The general monitoring methods are as follows: [0004] 1) After the sensors are laid out, it is c...

Problems solved by technology

[0004] 1) After the sensor is deployed, it is carried out by manual collection; due to manual collection, the time is delayed, and the usability is poor due to the strong time-varying construction, and manual recording is prone to recording errors or omissions;

[0005] 2) The automatic collection of data is realized by sensor layout and informatization. Usually, the personnel of the hardware company and the software company set up the plan. Since the hardware company and the software company do not understand the construction process of the structure, the selection of the location of the monitoring point mainly depends on The owner (general contractor) chooses, but the owner is not clear about the concept of informatization, which leads to the inappropriate selection of the location of the monitoring point, which makes it easy to miss the discovery of risk problems
