| With the continuous and rapid development of modern urbanization,the increasing number of population and the shortage of land resources have become a problem that can not be ignored.With the rapid development of industrialization,the wide application of high buildings is a good solution to the rational and effective use of land resources to alleviate the tension of the existing land resources.However,the high-rise building is different from the ordinary housing construction.The pile foundation is not only complex,but also requires high load bearing.Especially in the process of construction,if the pile foundation has problems,it will inevitably lead to the slope of the building,which will directly affect the safety of the builders and the living users.The verticality of buildings can be monitored effectively and timely,which is the important foundation for ensuring the safe construction and normal use of high-rise buildings.In this paper,the wireless sensor technology is applied to the monitoring of the tilt angle of the building,and a monitoring system based on the wireless tilt sensor is designed,which can monitor the building in real time.The application of this technology breaks the shortcomings of the traditional building tilt monitoring method,which is another meaningful attempt of wireless sensor network in the field of architecture.The focus of the paper is the design and simulation experiment of the monitoring system of the building tilt angle,and the processing method of the wavelet transform for the non-stationary vibration signal collected by the sensor in detail.By building a building model and simulating the process of high building tilt,the data is transmitted to the upper computer by SCA100 T tilt sensor and radio frequency transceiver module.The change data of high building inclination angle is obtained in real time,and the noise signal is removed by the time frequency characteristic of wavelet transform to obtain the true inclination curve and the number of processing after the building.According to the processing data,the data of the actual displacement of the building are obtained by the inclination calculation,and the prospect of further research is made. |
