According to TU developed a two-tier system, which can improve the accuracy of control and management of process of welding. On the lower level of direct digital control system to control the quality of welded joints algorithm based on "fuzzy" logic, which allows for blurring the boundaries of permissible deviations, the distribution process parameters within tolerance and mutual influence of combinations of Quality Score joint. Control of technical state of equipment is carried out on this test and functional diagnostics. To ensure stable energy equipment designed stabilizing the input voltage welding transformer with power from the electrical grid and the two-phase converter frequency and number of phases for three-phase power network. At the top level in the diagnostic center Ukrzaliznytsia performed statistical analysis protocols welding rails that come with the industry to identify abnormalities that are difficult to control direct measurements, for example, poor performance of auxiliary operations preparation rails before welding, the deviations of physical and chemical properties of metal rails unsatisfactory compliance welder manufacturing operations, poor conditions of production. Algorithms and means of automation have been experimentally tested and can be recommended for further implementation in production Product Description popup.authors Гавриш Валерій Семенович Руденко Петро Михайлович popup.nrat_date 2020-04-02 Close
