Ananieva O. The development of theoretical bases of the construction of jamproof systems of railway transport management.

The aim of the research is the process of transmitting and processing information signals in inductive communication channels of automated control systems of railway transport management. The object of the research is methods and means of signal reception and processing which ensure jamproofness of railway transport control systems. The research has been carried out with the application of up-to-date methods of field theory, the theory of electric circuits, communication, optimization, synthesis, mathematical modelling. As a result of the work an acute scientific-applied problem of the formation of jamproof systems of railway transport management by means of further development of scientifically grounded methods, models, technical means and strategies of forecasting the process of propagation, transmission, reception and processing of information signals in the communication channels of railway automatic equipment systems has been solved. A dynamic model of a signaling channel of a continuous cab signaling (CCS), that allows establishing the dependency of the influence of train speed on the functioning of a rolling stock automated control system. The synthesis of jamproof numerical code receivers of CCS and information signals of audio frequency track circuits makes it possible to reduce losses from unscheduled train stops and the reduction (temporary limit) of their speed due to the failures in the functioning of railway automatic equipment by 12-15%. The introduction of the above mentioned developments makes it possible to reduce the losses from train delays due to the failure of the existing signaling, centralization and blocking devices which depending on their character lead to service interruption. Their scope of application are automatic blocking systems and enterprises of development and design of methods of the existing collision avoidance systems of train operation.
