Authors describe principles of formation and equipment for transmission of data to monitoring
center for transport traffi c on rail crossings on semi-automatic line block safety improvement.
Data about automatic level crossing operation collected by signal point diagnostic
machine (ADSU-24/16) is transmitted to the data hub of diagnostic and monitoring
central offi ce (CPDM) using GSM-channel. Rail crossing relay cabinet contains GSMmodem
connected to information collecting devices by RS-485 interface; CPDM room
contains GSM-router, interacting with the hub by Ethernet.
It is shown on the example of relay automatic signaling that under the absence of physical
link and clock duty of traffi c control service personnel on the rail crossing digital signals
from relays and analog signals from operating devices are being collected automatically.
Principal schematics of information transmission could be the initial data for NSI formation
within APK-DK software adaptation.
