Our Axle Counter BROS is used to control occupancy of the railway sections. The device is placed into a standard 19-inch 3U height rack and it is mounted inside the relay room of the railway station, automatic block system, or level crossing.
The Axle Counter BROS uses sensor pairs (SP) at the end of each section and it counts in axles that have entered the section, and counts out axles that have left the section. Sensor pair consists of two sensors (wheel detectors) which are placed next to each other on the rail.
In addition to the basic function of detecting the presence or the arrival of the train wheel, sensor pair also provides detection of the direction and speed of rail vehicles.
KEY FEATURES
Providing outputs for 8 sections and having up to 12 directly connected sensor pairs, BROS device is perfectly suitable for usage within station interlocking system, as а relatively small number of devices can control all sections of the small, medium or large railway stations.
In the case using BROS for controlling occupancy within automatic signaling block (ABS), only two wires are enough for communication with adjacent axle counters, alternatively optical fiber communication can be used for communication between two BROS devices.
BROS has two modems, which enable communication with maximum two neighboring axle counters, which is important for usage within ABS.
BROS supports all section topologies. Configuration stored in non-volatile memory provides all possible combinations between sensor pairs and relay outputs.
Reliable detection for train speed up to 350 km/h
Device fullls SIL 4 requirements according to CENELEC
standards EN 50126, EN50128 and EN50129
