INTRODUCTION

This capsule records the navigation data necessary to plot a ship’s movements for the last 12 hours before loss of power. It’s application is on

·          Workboats, river and coastal vessels.

·          Vessels outside the scope of the full IMO/IEC VDR.

·          Vessels with small radars, which do not have an output for a VDR.

 

     VDR VR2272
   

The system does not pretend to be a full VDR with its deep submergence and fireproof memory capsule which stores huge amounts of data, radar, voice and radio communications. If you need all that then fit the AMI full VDR.  The important thing is that this is a simple, no frills, automatic “black box” data recorder. It does not attempt to be a “course and data recorder” which is another AMI product.
 

SYSTEM DESCRIPTION
A memory capsule in a rugged diecast aluminium enclosure is mounted outside the bridge. A single screened cable connects to the KW950 inside the ship.

The KW950 is the data controller for the capsule, connecting to

·    DC power 24 volts.

·    GPS data (Date, time, latitude, longitude, course and speed over ground.)

·    Heading, magnetic or gyro (NMEA 0183.)

·    Wind data, rudder angle, RPM, pitch, and thrust data.

Indicators and controls

  • A PC is plugged in to download & replay the capsule data.

  • Illumination and indication of good operation

 

   
SPECIFICATION

 

INPUT:      2 NMEA 0183 or IEC 61162 4800 baud data channels

OUTPUT:   1 NMEA 0183 data channel

POWER:   10 to 32 volts DC at 0.2 amps.

CAPSULE: 260 x 160 x 90 mm painted brilliant 

 

                 orange with  mounting bracket. The memory is permanently encapsulated to protect from water and heat.

JUNCTION BOX:       170 x 120 x 55 mm diecast box, duck egg blue.                          

CABLES:                  Miniature screened cables via cable glands.

REPLAY OF DATA:   Control is via proprietary NMEA 0183 data commands to the module from a PC.

                                KW950 in replay mode interrogates the capsule and replays the data.

                                Stop, start, go to memory location, data on/off, loop etc. 

DATA FORMAT:        The data saved is compacted and reconstituted into proprietary NMEA 0183 format.

                                The system saves only the essential and basic navigation data at 10 second intervals.

                                It is replayed in proprietary and NMEA 0183 standard sentences.
