DM-0333

Description

This driver is used to exchange information with the IHC IMS dredging computer as found on board Hopper/Cutter dredgers (TSHD/CSD).

The following input systems are supported:

USBL System
Pitch Roll & Heave Sensor
Gyro Compass
Tide Gauge
Miscellaneous System
Underwater Sensor
Dredging Sensor
Rotation Angle Sensor

The output system is capable of outputting a large number of parameters as specified in the message Format Description found below.

Database Setup

Cutter Suction Dredger

Set the IP broadcast range of the IHC dredging network and set up the correct port number. The default IP broadcast range is 172.16.255.255 and the default port is 2000.

The IHC computer which is Master will receive Position data from Qinsy and send out a response. The utility ComSwitch is installed on IHC computers and will perform the following functions: position data received from a Qinsy computer is transferred to the Master computer, the response from the Master computer is converted to a network broadcast so that multiple Qinsy computers can use the data.

It is possible that multiple Qinsy computers send Position data however the first that is received by IHC will be used and other computers are ignored. When the Position data is not received for 0.5 seconds then IHC will switch to the next available Qinsy computer. The time-out value of 0.5 seconds is a setting in ComSwitch.

The following systems are usually added to a CSD setup:

System	Description	Observations	Slot	Factor	Reference
Output System	Position Output
Underwater sensor	Draft Trunnion	Trunnion	Trunnion	-1
Dredging Sensor	IHC sensors 1	Density, Velocity	Density,Velocity
USBL System	Cutpoint		CutPoint	Positive Upward
USBL System	Spud		Spud
Pitch Roll Heave Sensor	Pontoon		VruPontoon
Pitch Roll Heave Sensor	VRU Ladder		VruLadder
Underwater Sensor	ROV depth	ROV depth	CutDepth	-1	Chart Datum
Miscellaneous System	Spud Carrier		Spud

It is also possible to send triangles to the IHC computer. This is a different driver which uses TCP/IP for communication. The description can be found at: Network - IHC Dredging Triangles (TCP) - 15

Trailer Suction Hopper Dredger

Set the IP broadcast range of the IHC dredging network and set up the correct port number. The default IP broadcast range is 172.16.255.255 and the default port is 2000.
