 CNT-1
Marine Seismic Controller
Features
-
Multi-tasking windows show real-time shot, gather, tape
status and observer’s log
-
Fast cycle times for all sources: air guns, water guns, even
sparkers and boomers
-
Real-time waterfall and bar graph noise displays
-
Auto switches up to 4 tape drives, audible operator alarms
-
‘Sure-Save’ eliminates lost shots by disk
buffering, even if ALL tape drives fail.
General
The CNT-1 Marine Seismic Control System combines
professional multi-tasking marine survey data management with the StrataView series of
high resolution, ultra low distortion seismic recorder.
Extensive Quality Control
Quality control monitoring of your data underlies the
design of the CNT-1. Watch a real time bar-graph of streamer noise levels, calibrated to
your streamer and measured between shots to avoid shots to avoid shot noise. Display each
shot in a user sizeable window with AGC or manual scaling, even at the fastest cycle
times. Build a user selectable near trace gather, displayed in a separate window to
monitor data quality, Or change your acquisition parameters on the fly - without stopping
the survey. The CNT-1 creates an observer’s log, displayed in its own window and
saved to disk for use in later processing.
True Multi-tasking on Multiple Platforms
The CNT-1 controller system runs under the Windows NT
operating system on either our splash-proof, ruggedized computer for portable applications
or built into a rack mounted StrataView seismograph.
Specifications
Interfaces to: StrataView R or RX System, 12
to 480 channels.
Data Displays:
-
Shot display
-
Near Trace (Common Offset) Gather
-
Log file shows tape status, acquisition parameter changes,
channels exceeding noise threshold, navigation and other external input strings
-
Noise histogram with user definable thresholds
-
Shot timing bar-graph
-
Gun energy bar-graph
Audible Warnings: System is user
programmable for audible warnings for several cautionary or error conditions:
"Tape Drive Full, Switching Drives"
"Tape not ready, going to disk"
"Tape Drive Rewound, replace tape"
"Peak noise threshold exceeded"
"Trigger time threshold exceeded"
"Overdriven channels warning"
"Navigation Input not received"
Tape Drives: DAT, DLT, 3480, 3490 SCSI
drives, other SCSI drives consult factory. Automatically switches between drives when one
is full or disabled.
CPU: Pentium PC based.
Configurations:
1) Portable, ruggedized, splash resistant 12
Volt control computer with built in LCD 640 x 480 display. Suitable for system from 12 to
120 channels. Includes external 640 x 480 video for separate monitor.
2) Portable, ruggedized 12 Volt control computer
with high resolution graphics card to drive external CRT with 1280 x 1024 resolution.
Suitable for systems from 12 to 480 channels. Requires separate monitor.
3) Rack mount computer with external monitor
Portable system can also be mounted in a 19"
rack using optional mounting kit.
Navigation, Gun and Streamer Position Input: Data accepted via RS-232 at sufficiently high baud rate to not effect cycle time.
Provide specifications of your system.
Tape Management: Tape Status can be
displayed continuously in its own window and monitors writing and ready operations. Robust
error checking reduces or eliminates the need for additional read-after-write or
read-while-write systems.
Sure-Save Data Protection Feature:
In the event that all tape drives fail, the CNT-1 system automatically buffers data to
disk, recording up to several hours of data until the problem is addressed.
