The solution to this problem is based on graph theory, process modeling and the use of microelectronic devices. A multigraph of the Petri net has been developed and investigated for various modes of operation of anti-repeat relays. The schematic diagrams of the microelectronic unit are given. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.eninfo:eu-repo/semantics/closedAccesselectromagnetic relaysgraph theorymodelingrailway transportConference Object10.1007/978-3-031-51521-7_212-s2.0-85184819970168Q4161718 LNNS
