Seismic damage investigation system based on smartphone

Abstract

The invention provides a seismic damage investigation system based on a smartphone and belongs to the technical field of seismic damage investigation. The system comprises three modules, i.e., a mobile phone module, a web page module and a database module, wherein the mobile phone module is mainly used for acquiring data, the web page module is mainly used for transmitting, displaying, viewing and managing data and integrating system functions, and the database module is mainly used for loading a database. The mobile phone module and the web page module can be used for carrying out data uploading and downloading directly, and the web page module and the database module can be used for carrying out writing and reading on the database. The system covers a plurality of links such as data acquisition, reduction, visualization and information sharing, so that human intervention is greatly reduced, efficient and convenient building seismic damage investigation is achieved, and a convenient, efficient and intelligent integrated tool is provided for the building seismic damage investigation.

Description

technical field [0001] The invention relates to the technical field of earthquake disaster investigation, in particular to a smart phone-based earthquake damage investigation system. Background technique [0002] In civil engineering, earthquake damage investigation refers to the process of conducting on-the-spot investigations on the damage of buildings, roads and bridges, etc. Accurate judgments provide reference for the government to organize earthquake relief, and provide first-hand information for engineers to conduct structural seismic analysis. [0003] After each major earthquake, the government often organizes relevant departments and scholars to go to the site to investigate the earthquake damage and obtain data on damage to houses, such as the recent Ludian earthquake, Yushu earthquake, and Nepal earthquake. . Some new survey methods have gradually been applied to practical work, such as satellite measurement and control, optical remote sensing, and drone photog...

AI Technical Summary

Problems solved by technology

Some new survey methods have gradually been applied to practical work, such as satellite measurement and control, optical remote sensing, and drone photography; however, it is difficult to obtain specific earthquake damage indicators for each house, and the judgment of the earthquake damage level of a house strongly depends on the investigators Therefore, field visits by investigators are still the most reliable and most commonly used way to obtain earthquake damage data

[0004] However, due to the lack of powerful tools, investigators still follow the traditional methods of data collection and organization: such as recording the earthquake damage information of a certain house with pen and paper, taking pictures of the scene with mobile phones, and then using spreadsheets to sort out the data collected every day. Earthquake damage data

This method mainly has the following three major problems: low correlation of data structure, large amount of labor for data analysis, and lack of platform for data sharing
