CENTRAL CONTROL UNIT (CCU)

Expandable and powerful Ethernet
data network is used to connect the
HCI to the various modules.
The raw or processed data are recorded on magnetic media, either a reel
or a cartridge drive.
Digital filtering may be performed on the recorded or playback data, to
display notch- or bandpass-filtered seismic traces on a digital camera.
•
Peripheral equipment such as a printer or digital camera can be connected
to the CCU to provide data, operation log and parameter hard copy. The
system has the capability to display a noise monitor of the complete
spread in real time, without any delay or missing data due to segmented
processing.
1.3.1 HUMAN COMPUTER INTERFACE (HCI)
The operator controls the complete system through a HUMAN COMPUTER
INTERFACE (HCI) based on a workstation with a high resolution colour monitor, a
keyboard and a mouse. A multi-windowing system allowing flexible and versatile
screen extensions gives immediate access to all parameter settings.
The major functions of HCI software include :
-
Normal operation control (user-friendly parameter setup, update, and
display for the entire system, including all VE416/VE432 Vibrator
electronics parameters).
-
Permanent high-resolution graphic display of the complete field electronics
connected to the CCU, including ancillary units and the shot point. The
graphic display allows interactive graphic selection of the spread, and
energy monitoring prior to and during the shot.
-
Easy to set up and update shotpoint planning.
-
Preplanning In/Out capability : SN 388 parameter script files can be saved
to and/or loaded from an auxiliary computer. Compatibility with a
standalone processing support converter is provided.
-
Neat display of system activity.
-
Display, analysis and storage of spread test results.
-
Automatic log of observer report data.
-
Graphic display of planned source and receiver positions, possibly
superimposed on a digitized map and/or a graticule. Real-time tracking of
actual vibrator positions and centre of gravity of actual source position
(with VE416/VE432 and GPS).
-
Source and Receiver attributes (e.g. vibrator peak force, geophone
impedance etc.) can be colour-coded and displayed geographically.
