Abstract
The object of the research is the technical state of the construction objects. The most problematic part of the task is the fact that with the use of existing traditional control systems based on known methods for calculating dispersion, correlation, spectral, static and dynamic characteristics, it becomes possible to detect only pronounced changes in the technical state of the controlled object. And this, in turn, prevents the timely conduct of an operational set of measures to prevent premature wear, damage and the appearance of defects. In the course of the research, technologies are developed for robust noise analysis of noisy signals received at the output of sensors installed in certain nodes of a construction object, as well as spectral analysis of noise. Due to the use of mentioned technologies, it becomes possible to eliminate the influence of noise on the adequacy of the results of monitoring and to conduct continuous control of the technical state of the construction objects in order to detect the latent stage of the origin of the changes, which is currently impossible with the application of existing algorithms and technologies. On the basis of stated technologies, the basic principles for the development of a system for the continuous control of the latent period of the origin of changes in the technical state of construction objects are proposed. Identification of the latent period of the origin of changes allows reducing material and time costs due to timely carrying out preventive maintenance work.
Highlights
It is known that the monitoring system of the technical state of building structures should contain:– a subsystem of primary sensors; – a subsystem of transfer and accumulation of primary data; – a subsystem for received data processing and presenting results to a specialized service
If there is a system of continuous controlling of changes in the technical state of building structures based on robust noise and spectral technologies, it will be possible to identify both the initial stage of micro-changes occurrence after the training stage of the system and the latent period of their occurrence [1]
Technologies in which robust noise characteristics of noisy signals detected by sensors installed on a controlled object are used as informative signs for identifying the origin of changes in the technical state of construction objects are developed
Summary
It is known that the monitoring system of the technical state of building structures should contain:. For many construction objects, there are certain difficulties in predicting the change in the state of the object in the early stages of the origin of faults using known methods of calculating dispersion, correlation, spectral, static, and dynamic characteristics. For the time being, using known methods of calculating dispersion, correlation, spectral, static, and dynamic characteristics, in most cases, for many construction objects, there are certain difficulties in predicting changes in the technical state in the early stages of the origin of faults. In some nodes of the studied building structure Actual is their timely detection which will make it possible to predict changes in the technical state of the building structure, and can be used to prevent and avoid serious damage. The paper considers one of the possible options for solving the problem of monitoring the technical state of construction objects using robust noise and spectral analysis of noisy signals, as well as the spectral noise analysis [1]
