TELECOMMUNICATIONS ACCESS SYSTEM FOR RAILWAY INFRASTRUCTURE FACILITIES ON THE RAILWAY SECTION TO STATION EQUIPMENT Russian patent published in 2021 - IPC B61L27/00 H04B10/25 H04M3/56 

FIELD: railway facilities.

SUBSTANCE: invention relates to the means of organizing a railway section connection. The system contains station and section access points that are sequentially connected to the fiber of the fiber-optic communication line between the stations that limit the section. Each station access point includes an Ethernet switch connected via a transceiver to the fiber, and a mini-PABX connected to the corresponding Ethernet switch interface for connecting to analog subscribers via a long-distance switch, and through the OCS equipment for connecting to the remote control unit of the station operator on duty, and the corresponding Ethernet switch interface is connected to the station switch of the interstation data transmission line, and other Ethernet switch interfaces are designed to connect video surveillance equipment and remote control operation and remote signaling station equipment. Each section access point includes an Ethernet switch connected via transceivers to an optical switch included in the fiber of an inter-station fiber-optic communication line, while the corresponding interfaces of the Ethernet switch are designed to connect an intercommunication device for section communication, an adapter for connecting to a MAVR communication device and the remote control operation and remote signaling section equipment. The battery included in them is used as a power source for the Ethernet switch, transceivers and the control circuit of the optical switch of the section access point when connecting the intercommunication device of the section communication or the adapter for connecting to the communication device of the MAVR, and when connecting the section equipment for remote control operation and remote signaling, a stationary power supply unit is used.

EFFECT: improved communication reliability.
