TRAIN TRAFFIC CONTROL SYSTEM Russian patent published in 2022 - IPC B61L27/00 

FIELD: train traffic automatic control.

SUBSTANCE: invention relates to means for automatic control of train traffic at hauls and stations. The system contains an automated workplace of the DNC control center, including a processor with an information input/output unit and a display unit, and a stationary radio modem for a digital radio communication channel. On train locomotives, on-board equipment includes an on-board radio modem of a digital radio communication channel for interacting via a radio channel with a stationary radio modem, an auto-guidance system, a locomotive safety device and a radio channel gateway connected via an external locomotive CAN bus to an onboard radio modem, and via an internal locomotive CAN bus to the gateway CAN-MVB, connected via the internal locomotive CAN bus to the locomotive safety device, and via the MVB bus to the autopilot system. Stationary and on-board radio modems contain built-in transceivers for meter and decimeter radio wave bands with an automatic frequency range switch. The processor and the gateway of the radio channel of the on-board equipment of the locomotive of each train include the corresponding software module for controlling the protocol of interaction between the train dispatcher and the train driver and the software module for encrypted data exchange. The processor encrypted data exchange software module contains a cryptographic data protection module with a secure packet data virtual network coordinator, and the radio channel gateway encrypted data exchange software module contains a cryptographic data protection module with a secure packet data virtual network client base. The radio channel gateway also includes a software module for the exchange of unencrypted data. The corresponding inputs/outputs of the processor and the radio channel gateway for the exchange of encrypted and unencrypted data are connected to the decimeter radio wave transceiver of the stationary and on-board radio modem, respectively, and other corresponding inputs/outputs of the processor are connected to the VHF transceiver to control the interaction protocol between the train dispatcher and the train driver. and radio channel gateway.

EFFECT: increasing the level of security of train traffic control due to automatic control of the protocol of interaction between the train dispatcher and locomotive drivers using cryptographic data protection.
