Analysis of the algorithm for the operation of anti-repetition, auxiliary final and intermediate relays in the dialing group blocks NM2P and NM2АP, which control two combined shunting traffic lights of the railway automation and telemechanics system

The article analyzes automation and telemechanics systems, as well as signaling, centralization and communication devices at railway stations. The question of improvement of group dialing blocks (NM2P and NM2AP) controlling two combined shunting traffic lights of the “BMRM” system, which is considered to be one of the systems of railway automation and telemechanics, i.e. creation of their microprocessor variant, is considered. At the same time algorithms are being developed and software is being created for each working circuit of anti-repeat, auxiliary final and intermediate relays. It is planned to create a prototype of the above-mentioned NM2P and NM2AP units based on the developed software and industrial controllers.
