Study of features of information technologies in the construction industry

Information technologies are used in almost all areas, while each of the areas has its own specifics, and the construction industry is no exception. The paper consistently explores the directions in the field of IT technologies in which the features of this subject area should be taken into account. First, the problem of converting the original analog information into a digital code is considered. The importance of this issue lies in the fact that the loss of useful information at this stage is almost impossible to compensate for further processing. Since in the construction field automated systems often operate in conditions of industrial interference, measures should be provided to increase noise immunity. A number of such measures are considered: differential signal transmission, on the basis of which two RS-485 and CAN interfaces that are in demand in practice are built. Reception of signal transmission “Twisted pair” - has found wide application in construction largely due to the use in the floor (horizontal) subsystem of structured cable systems SCS. The features of the use of modern information technologies in the construction industry are investigated, MV machine vision technology is considered first. Specific solutions that can be implemented with the help of the MV system are formulated, the importance of integration with other IT technologies - primarily the Internet of Things and Big Data - is stated. Then the direction is investigated: quality control of welded products in the structures of a construction site: machine vision allows you to bring the solution to a qualitatively different level, especially when combined with Big Data technology. The possibility of using machine vision in the production of building materials is considered. The possibility of effective use of the machine vision system installed on an unmanned aerial vehicle (drone) in the construction of high-rise buildings, large bridges, dams and other large-scale objects is investigated. The variant of using MV based on the use of a geostationary earth satellite for monitoring construction projects located in a remote area with a weak (or absent) communication infrastructure is analyzed. In all applications related to machine vision, the possibility of integration with other new IT technologies is being studied: Cloud Computing, IoT, Big Data, etc.
