For optimal visualization of the systems on board a ship, the visu-
alization of the monitored ship sensors, their measuring points and
status messages on the Color Display AHD 880 TC’s graphic user
interface is tailored to the project’s specific scope.
To display analogue measurands conveniently and clearly, graphic
representations, such as scaled round instruments, bar graphs,
and digital displays are used or combined with one another, also
allowing for the integration of threshold value ranges, e.g. for pre-
warnings and alarms.
As a rule, binary measurands are displayed in tabular format with
measuring point names and status display.
When a value reaches a critical level, a warning or alarm is trig-
gered and indicated on the display, depending on the predefined
threshold value configuration. In addition, an integrated buzzer
sounds an alarm which can be acknowledged with a key press.
All recorded and pending alarms are listed in chronological order in
a table. Each alarm is displayed with the measuring point name,
current value, alarm type, and time of occurrence.
To indicate alarm conditions, a general alert message with the
number of pending alarms is superimposed onto the measuring
point pages.
A service page, on which the measuring points and alarm condi-
tions of all sensors can be viewed in a clearly displayed manner, is
available for startup and maintenance purposes.
On the configuration page, the user can set the display options for
the Color Display AHD 880 TC according to his own needs. He can
set the system language for the screen texts, select the unit sys-
tem (metric or Imperial), and the internal clock time.
Connecting a GPS receiver allows for display of the cruising
speed. If the ship is equipped with according engines with motor
displays to indicate engine data and alarms, selected data from the
engine display can also be used on the ship alarm system’s Color
Display AHD 880 TC via an additional CAN-bus communication to
calculate and display fuel consumption and remaining range, for
example.
