The article discusses the concept of an electronic system for ensuring the quality of anti-icing processing of sidewalks and other elements of road construction. The object of research is the quality of particle distribution of anti-icing material. In particular, such quality indicators as the width of the processing band, the density of distribution of the material over the coating and the degree of lateral deformation of the processing zone are considered. The subject of the research is the general principle of the control system for the numerical values of the distribution quality indicators. Such a system is based on mathematical models of the movement of individual particles of a material along a flat rotating disk and in air. The original mathematical basis was developed by the authors of the article, taking into account the analytical equations of motion of a particle on a rotating horizontal disk obtained earlier by other researchers and using Newton’s second law. The article describes the algorithm for the functioning of the distribution quality control system, which takes into account geometric, regime and meteorological parameters. The system is designed to work with a symmetrical way of feeding material from the tray to the disc. In addition, the physicochemical properties of the particles of anti-icing material and numerical quality criteria are taken into account, such as the required width of the processing strip, the rate of density of distribution (consumption) of the material and the maximum permissible degree of lateral deformation of the processing zone. The block diagram of the system is presented. As a result of the operation of the proposed system, it becomes possible to change the values of the operating parameters of the equipment in the process of material distribution, providing the required values of quality indicators. Thus, the negative impact on the ecological environment of the city will be reduced and the economic efficiency of anti-icing processing of sidewalks will be increased.
