Network - IHC Dredging (ASCII) - 31
Description
This is a driver to exchange information with the IHC DigiSys system.
The main function of the IHC DigiSys system is to present dredging information on board a cutter suction dredger.
It is capable of sending and receiving ASCII-based messages.
The message that is sent by the driver contains the following types of information:
Tide information: used tide value and status
3D position of the pontoon in projection grid coordinates including position & height status
Work spud chainage and offset to the active center line
Projection grid convergence
Some spare fields
The message that is received by the driver contains the following types of information:
Draft of the pontoon
Spud carrier position
Pitch & roll of the pontoon
Tide information: used tide value and status
Heading of the pontoon
Density & velocity of mixture
Cutter head identifier
Ladder angle
Roll & pitch of the the work spud
Relative & Absolute position of center of cutter
Relative & Absolute position of cut point
Relative & Absolute position of calibration point
Relative & Absolute position of work spud tip
Relative & Absolute position of auxiliary spud tip
Absolute position of starboard anchor
Absolute position of port anchor
10 user configurable observations

Coding Notes
Encoding Notes
Tide Information
The tide value only contains a value if Qinsy is actively using a tide observation for the height observation. If this is the case the tide status will be set to 'valid'.
Position Information
The position information as outputted is using the survey projection and vertical chart datum as its horizontal & vertical references.
Work Spud Information
The work spud information is computed using the position of the spud node as selected in the 'Dredging Parameters - Positioning' dialog in the Database Setup Program.
Project Grid Convergence
The convergence field uses the following convention: Convergence = True bearing - Grid bearing.
Spare Fields
The spare fields are currently not used and therefore remain 0.0.
System Interfacing
The driver is normally connected to the DigiSys system using a network connection and uses the UDP protocol as means of communication. The driver is redundancy enabled.
This means that the driver will adhere to the settings as found in the 'Controller - Output Driver Settings' dialog as shown below:
System Configuration
The DigiSys system should be configured to use the same UDP port as set in the Qinsy template database.
Qinsy Configuration
Database setup
The driver is able to extract information for the following system types from the input message:
Position System
The following absolute positions are available from the input message:
