Improvement of the scientific bases of creating means of automation of documentation of devices of railway automation and telemechanics

Calculation of foundations using elastic models simplifies the calculation of loads and impacts on foundations. However, in some cases they can significantly distort the real deformations, foundation efforts and in some cases cause their damage. In practice, designing and calculating foundations using these models, there are cases of excessively high concentrations of bending moments and shear forces, which requires a high percentage of reinforcement in these nodes. Sometimes, for example, with distributed loads, with the real presence of such efforts, calculations performed on models with a bedding coefficient show, on the contrary, their absence. The type of the adopted model and the rigidity of the foundation structures have a significant impact on the calculated deflection of the beam. The value of the adopted values of the model parameters also has a great impact on the calculation results. Calculation models in the area of contact with the soil base, the reactive pressure of the foundation P (x) linearly depends on the coefficient of local soil compression C1 and the shear resistance of the soil C2.

Incidents of train collisions with creatures on railway tracks are one of the major problems for railway transport today. The scientific article presents the results of the analysis of cases of trains hitting people and creatures on railway sections. Taking this into account, the aim of the scientific work is to develop a system of automated warning messages to creatures on railway tracks of approaching trains. In the creation of the system, the notification of the approaching trains to the creatures was selected based on the frequency of hearing of the creatures that gather a lot on the railway sections. In the article, the working algorithm of the system for notifying creatures of the noise generator of the approach of trains, as well as the types of auto-blocking systems on railway sections, to start the noise generator that transmits the message of the approach of trains, if the railway tracks are equipped with the auto-blocking system, the rail chains or the railway tracks are equipped with a semi auto-blocking system connecting the road sensors that notify when the train is approaching to the contacts of the road relays, and recommendations on the selection of frequencies for the noise generator of the train approach warning system based on the hearing frequency of the creatures that gather in large numbers around the railway sections.
