Research And Implementation Of Building Health Monitoring Based On Intelligent Communication Platform

Due to the needs of economic and social development,buildings such as houses and bridges are increasing.However,with the passage of time,the service life of some buildings can be as long as several decades or hundreds of years.Long service time leads to the aging of materials and accumulation of structural damage,which is easy to cause disasters and accidents.In addition,there are many ancient buildings in our country,and the protection of these cultural heritage needs attention.There are some solutions for health monitoring of buildings,but they are costly and inflexible.Based on intelligent communication platform,this thesis designs a set of building remote monitoring systems.system using sensor acquisition,data preprocessing and transmission,background data analysis and other technologies.It plays a positive role in building maintenance and alarm,and also helps to protect people’s property and life safety.Firstly,according to the characteristics of long-term building monitoring,large number of sensors and complex detection site environment,a sensor monitoring scheme of building and bridge is given.The data acquisition system is designed according to the knowledge of sensor networks.The functions of building inclination acquisition,sensor equipment positioning and anti-electromagnetic interference are realized.Secondly,according to the data transmission ideas of industrial Internet,an intelligent communication platform is designed.Two transmission schemes are adopted to meet the standard communication needs of enterprises and personalized communication needs.One is the narrowband Internet of Things data transmission scheme,which uses the narrowband Internet of Things transmission module.The other is a software radio transmission scheme.zynq is used as the processor and AD9361 as the RF processing core.The differential dual data transmission data interface of zynq and AD9361 is designed to realize the data interworking between zynq and AD9361.The 2FSK modulation and demodulation scheme is simulated by Matlab.GNU Radio is used to verify software Radio platform.Finally,the data acquisition module is combined with the intelligent communication platform,and the cloud data analysis and data visualization function are realized based on the MQTT protocol.The results show that the designed platform has good interface flexibility and data transmission performance,which has great application value for building health monitoring projects.
