Determination of the optimal parameters of the control sensor at the crossing in the control mode

On railway sections where there are intersections with road transport, control systems for crossing signaling with auto barriers are arranged. To control the entrance of the train to this section, track circuits with insulating joints are used. Such circuits have a number of significant drawbacks, one of which is the coming off of insulating joints, as well as breakage of the track circuit, which give 45% of the failures of automation systems on the haul. In this article, a study was made of a crossing track circuit with a tone frequency for the control mode. For the study, mathematical expressions for determining the most unfavorable moment were derived, an algorithmic expression for the control mode coefficient was presented, which gives more accurate information about the presence of damage. As a result, a block diagram was developed and graphs were displayed on the simulation model showing the influence and determination of the control mode of operation of the jointless tone track circuit. In conclusion, the results of the study are summarized

INFORMATION TECHNOLOGIES FOR FORECASTING CAR DEPOT INVENTORY USING CORRELATION ANALYSIS

The analysis of the statistics of expenses of components and spare parts of mobile units of the car depot is carried out, the trend of changes in expenses is determined and the mathematical apparatus for forecasting the need for spare parts is selected, which provides the maximum accuracy of the forecast.Forecasting of changes in the parameters of various systems is performed using information about the factors that affect the predicted parameter, using regression models. A multivariate regression model is proposed that takes into account the factors that affect the consumption of spare parts and establishes the density of the relationship between the factors themselves
