description
System for automatic level crossing free detection The systems for automatic level crossing free detection (GFR) serve for the safe monitoring of the danger zone at the level crossing. At installations with full barriers this system replaces the demanded optictal monitoring of the danger zone. Up to now, REM has successfully provided already more than 25 BS2000 installations with the GFR radar system of the company REM DE, hereby realising an effective solution for the automatic level crossing free detection. We offer such solution as integrated complete systems under our guarantee.

Radar scanner
Radar scannerThe Honeywell radar scanner is an auto-
matic monitoring system for detection of
objects (roadway traffic) located between
the gates of a level crossing. The system
sends an output signal “crossing clear” or
“crossing occupied”.
The detection of obstructions occurs by
means of a radar sensor for measuring
distances. This sensor is attached to a ro-
tating platform in a weatherproof casing.
With every rotation the radar generates a
horizontal scan of the section of roadway
between the railway gates.
The external limitations of the area moni-
tored are marked by reference reflectors
making it possible for the system to moni-
tor its function.
In order to detect an object located on the
level crossing, the echos recorded with
each scan are compared with reference
data in storage.
If an object is found to be inside the area
being monitored, then a corresponding
signal is sent to the level crossing control
system that prevents clearance for the train
passage.
The system functions are constantly being
checked by means of extensive self-tests.
The system meets the requirements of
EN 50129 with safety integrity level 3.
