DEVELOPMENT OF THE CONCEPT OF THE INTELLIGENT DATA PROCESSING UNIT IN THE BRIDGE MONITORING SYSTEM USING SCANNING TECHNOLOGIES
Abstract
Background. The aim of the work is to find ways to automate the process of data processing while monitoring the technical condition of bridges. The object of the research in the article is a system for monitoring the structures of transport infrastructure of various types, based on the technology of three-dimensional laser scanning, as a way of assessing the degree of wear. Subject of research is an automated complex for processing laser-scanning data – an intelligent monitoring unit. Creation of his concept. Materials and methods. The study was performed by the synthesis method of a model of a monitoring system, tested by the team for special needs, followed by its decomposition and partitioning into the main structural elements. Results. The structure of the created monitoring system for bridge structures has been drawn up. The concept of its intellectual subsystem is developed and described. A complex is presented for creating three-dimensional copies of real objects in the form of its model of the “black box” type with an outline of the mechanism of its operation. Using the IDEF0 methodology, a block diagram of the operation and interaction of the elements of the intelligent bridge monitoring subsystem with a mathematical description of its states is formed. Conclusions. As a result, conclusions about the most effective ways to modernize the bridge monitoring procedure as a whole are drawn. The proposed solution in the form of a single intelligent monitoring system eliminates the identified problems. In addition, such a complex can take into account the speed and dynamics of the development of deformations, which is a very important criterion when making forecasts of the remaining service life of the facility and recommendations for repair work.
