Drivers Manual

Teledyne RDI WorkHorse ADCP series - 05

Description

Driver with user-interface to decode various items from an RD Instruments (RDI) Acoustic Doppler Current Profiler (ADCP).

The following systems and observations can be created for this driver:

  • Pitch, Roll, Heave Sensor: only pitch and roll are used, heave is not available
  • Gyro Compass
  • Miscellaneous Systems: salinity, pressure, temperature
  • Underwater Sensor: ROV depth, sound velocity
  • Acoustic Doppler Current Profiler

ASCII output format PD0 is supported. This driver has user interface to change parameters.

In addition to calculating the average values for speed and direction of the current, the data is also corrected for vessel movement.

Coding Notes

Decoding Notes

The RS-232 cable connection must have two-way direction, both receiving (Rx) and transmitting (Tx) data, since this driver will send commands to the unit and will receive data ensembles.

Encoding Notes

Below an overview of some of the commands that can be used to control the ADCP.
How to use these commands: see Active Driver Interface.

System Interfacing

No information available.

System Configuration

The system can be configured using the Active Driver Interface or with system specific software, for example WinRiver.

Database Setup

In the Qinsy Database Setup program, the following systems and observations can be created for this driver:

  • Pitch, Roll, Heave Sensor: only pitch and roll are used, heave is not available
  • Gyro Compass
  • Miscellaneous Systems: salinity, pressure, temperature
  • Underwater Sensor: ROV depth, sound velocity
  • Acoustic Doppler Current Profiler

For all drivers the following applies:

  • When using the driver with '(UTC)' in the name, the time as found in the message will be used.
  • If the driver is selected without '(UTC)' in the name the time of arrival in Qinsy will be used.
  • All drivers should use either with or without '(UTC)'. They should not be mixed.

Pitch, Roll, Heave Sensor

The driver is capable of decoding the pitch & roll from the input message

In order to decode the pitch & roll from the input message:

  1. Add a Pitch Roll Heave Sensor to your template and select the driver "Teledyne RDI WorkHorse ADCP series (R-P) (UTC)".
  2. Select the appropriate serial port.
  3. Set the appropriate serial port parameters. Instrument defaults are 9600 baud, 8 data bits, 1 stop bit and no parity.
  4. No 'Slot' information is required.

Heading System

The driver is capable of decoding the heading from the input message.

In order to decode the heading from the input message:

  1. Add a Gyro Compass system to your template and select the driver "Teledyne RDI WorkHorse ADCP series (UTC)".
  2. Select the appropriate serial port.
  3. Set the appropriate serial port parameters. Instrument defaults are 9600 baud, 8 data bits, 1 stop bit and no parity.
  4. The 'Slot number 1' field on the next page should be set to 'HDG'.

Miscellaneous System

The driver is capable of decoding a number of miscellaneous observations from the input message:

  • Salinity
  • Pressure
  • Temperature

In order to decode any of these miscellaneous observations:

  1. Add a Miscellaneous System to your template and select the driver "Teledyne RDI WorkHorse ADCP series (UTC)".
  2. Select the appropriate serial port.
  3. Set the appropriate serial port parameter. Instrument defaults are 9600 baud, 8 data bits, 1 stop bit and no parity.
  4. Select the appropriate value for the 'Slot 1' field.
    Available are:

    Slot 1 Observation
    SAL Salinity
    PRS Pressure
    TMP Temperature

Underwater Sensor

The driver is capable of decoding the transducer depth and sound velocity from the input message.

In order to decode the transducer depth and/or sound velocity from the input message:

  1. Add an Underwater Sensor to your template and select the driver "Teledyne RDI WorkHorse ADCP series (UTC)".
  2. Select the appropriate serial port.
  3. Set the appropriate serial port parameters. Instrument defaults are 9600 baud, 8 data bits, 1 stop bit and no parity.
  4. Select the appropriate value for the 'Slot 1' field.
    Available are:

    Slot 1 Observation
    DPT ROV Depth
    SND Sound Velocity

Acoustic Doppler Current Profiler

To interface the RD Instruments Acoustic Doppler Current Profiler with Qinsy:

  • Select system type: Acoustic Doppler Current Profiler
  • Driver: "Teledyne RDI WorkHorse ADCP series (UTC)"

Make sure you set the baud rate as high as possible and that the FIFO buffers of the serial port are disabled (set as low as possible).

Raw data storage is only needed for problem solving when QPS Support asks for this.

Select the location at which the ADCP is mounted:

Set the 'Max. cell count' to the maximum number of ADCP depth cells that you expect to receive from the instrument

Warning

There are no procedures to determine the alignment correction in Qinsy. Please refer to the manufacturer procedures to determine the heading offset.

Displays

The ADCP data can be shown in a number of displays

  • Navigation Display
  • ADCP Display
  • Observation Physics
  • Generic Display

Navigation Display

In the Navigation display the average speed and direction of the current can be visualized, using vectors and a text markup.

The values are corrected for vessel attitude:

  • The arrows show the direction of the current with text markup indicating the speed.
  • These settings are accessible and can be adjusted via the View Properties of the Navigation display.

ADCP Display

The ADCP display shows the ADCP current direction and speed data in the following charts:

  • Profile charts through the water column;
  • History charts on average and surface;
  • Compass view on average and surface;
  • Raw data.

Info

The information bar of the display can contain warnings on decoded ADCP data

Generic display

Both Raw and ADCP results data can be shown.

Computation Settings

There are additional controls (filters) in the Computation Setup that can influence how the average is calculated:

  • Depth outside (range)
  • Raw Data Quality flags
  • Speed outside (range)

Active Driver Interface

The user-interface can be found in the Windows task bar.

The driver is active, meaning commands can be sent directly to the unit by the user.
Use the Load button to browse for a configuration text file containing predefined commands.

Note that the EX Coordinate transformations/corrections needs to be set to 01000

The text file is a common method and is also used in other software.

Logging

When recording is enabled, the data is stored in the Qinsy database and can be used for Replay. The ADCP data is also available in the Generic Output.
