Functions

status of the wagon (loaded / unloaded).

shock detection (in the sense of shocks caused by shunting)

Position tracking by GPS

wagon speed and direction are calculated in the OBT and are

sent to the ground station (but only on request -polling)

alarm of low charge battery (two thresholds according to the

remaining operating time of less than 8 % and 4 %,

respectively)

6

Functions

The OBT exchange messages via SMS to the Ground Station

and a software update to the OBT via GSM data channel.

The OBT should be characterised by a unique identifier (SIM

identifier and Serial number)

The OBT is individually configurable.

The OBT can run in three different modes (active mode, sleep

mode, time table supervision mode) and is able to switch

automatically from active mode into the sleep mode.

7

Functions

The SMS sending interval cannot be determined according

the moving status of the wagon. The interval depends on the

actual OBT mode (active mode, sleep mode, time table

supervision mode).

A deviation from the reference of loading status can

automatically be reported to the Ground Station during time

table supervision mode.

Running / no running is detected during time table

supervision mode.

8

Functions

OBT can load 128 way-points. Each one consists of 2

wake-up times, tolerance radius and target status for the

sensors. The time table supervision function is time-controlled.

A special target detection feature is available only for the final

station of the time table in case of delay. This is an internal OBT

function which roughly calculates the expected time of arrival

(ETA).
