Research On Online Monitoring Technology Of Building Structure Settlement And Sliding

Buildings are state organs and enterprises normal production and operation of security is an important venue masses live and work.Since the passage of time,some of the structure of the building has undergone deformation,displacement,subsidence,sliding and other issues,a serious threat to life and property safety of residents,so monitoring technology research building structure put forward by the majority of scholars.Existing building structure monitoring,there are a lot of ways,but most of the traditional equipment were measured.In this paper,in combination with the civil engineering and information technology based on the on the buildings settlement and sliding on-line monitoring technology research.This paper is divided into three parts.The first part puts forward the method of sliding monitoring of building structure based on image processing technology,the second part presents the research on the construction of the settlement of the building structure based on the connected pipe pressure method,the third part is carried out on the field data graphical analysis and settlement prediction model is established.The main contents are as follows:(1)Proposes a monitoring method based on digital image processing structure with a two-dimensional displacement of the slide,to clarify the system measuring principle.(2)Based on pipe pressure method of building structural subsidence monitoring technology,building structure subsidence monitoring system design,analysis on the characteristics of the monitoring system,and the measurement principle described schematically.(3)Settlement of the monitoring system designed to be sized hardware devices,completed the development of appropriate data collection,storage and analysis software modules,and the software and hardware systems theory of experimental verification,in order to ensure the viability and stability of the system.(4)Through field research,the structure of the sensor is arranged,through the digital pressure sensor and tilt sensor data comparison,to obtain the settlement of the building,and the BP neural network settlement prediction model based on L-M algorithm is established.In this paper,the first part sliding displacement measuring principle of filtering method,color segmentation model and the center point positioning algorithm made research.Part in the second part of the settlement monitoring system software development using c # language development and design,through the hardware and software for data acquisition and storage.The third part is the practical application of the settlement monitoring system,pressure sensor collected data analysis,the No.13,No.16,No.17 monitoring points near the settlement occurred slowly,the settlement information of buildings in the southeast direction was obtained by mutual validation with the inclination angle sensor data,and the settlement prediction model of BP neural network was established.
