Abstract

The article notes the relevance of the use of the latest scientific and technical developments, in transportation management justified by the need to increase the intensity of train traffic and ever-increasing freight turnover while maintaining the safety of train traffic. The solution of actual innovative tasks on the application of electronic devices in railway automation and telemechanics devices will allow to increase the level of transportation safety. Digital information processing and frame modeling techniques were used to achieve this goal. The method of microelectronic implementation of blocks of the set group of the route relay centralization system functional purpose is considered. To formalize the description of blocks of the set group, the method of role frames has been developed, which allows to obtaining of unified information and mathematical support for microprocessor blocks of the set group that control the switching of points, the operation of shunting, and trainset signals. The software purpose of the coupled point control unit is to constantly survey the slot descriptions to determine a positive or negative response. Change of state〖g〗_“PU1,” g_“MU1” indicates the beginning of the procedure for setting a route passing through this point. Changes in the state of the variable g_“NKN,” g_“KN” control units of shunting and trainset signals determine the directions of the software when setting routes. The use of role frame models allowed to optimize the software structure of microcontrollers used to replace the relay contact hardware of the route relay centralization system.
