Programmable railway level crossing safeguarding equipment with communication coupling to external intelligent peripherals and the method for controlling this equipment's activity

摘要

The backed-up programmable control block (CB) of the level crossing safeguarding equipment (LCSE) is connected through the backed-up data transfer (DT) to remote intelligent peripherals (IP), which are located near the railway lines (RL) in the site designated for the safeguarding of the level crossings (LC), and which are partially or fully backed up, while the backed-up programmable control block (CB), backed up data transfer (DT) and remote intelligent peripherals (IP) are powered from a backed-up power source (PS) through backed-up power lines (PL).
