Welcome

Welcome to the CyScan (Dashboard) Operator's Guide. It has been written for operators of the CyScan system that use the CyScan Dashboard operator interface rather than the legacy CyScan Console.

Getting Started (see page 9) explains the basics that you’ll need to know before using

the CyScan system for the ﬁrst time.

The CyScan system can be installed either as a single-Dashboard serial system or as a multi-Dashboard Ethernet system.

The majority of the sections in this guide apply equally for serial or Ethernet conﬁgured systems and explain how to perform the various tasks necessary to operate the system and use it for tracking. These include

and Multi-Target Tracking (see page 27), Support Information (see page 44) and Troubleshooting (see page 49). The section Multi-Dashboard (Ethernet) CyScan Systems (see page 41) gives information speciﬁc to an Ethernet conﬁgured system.

Note that whilst we endeavour to describe the functionality of the Dashboard correctly in this document, we do not guarantee that it exactly represents the version of Dashboard that you are running, particularly after any future upgrades to the software.

System Overview

The CyScan System is based on a high accuracy laser sensor and provides positional information to allow automated approach and/or station keeping relative to a structure or vessel. It requires one or more reﬂective targets to be attached to the sides of the structure or vessel.

The CyScan system is designed to be semi-portable and straightforward to operate. Its key elements are:

The CyScan Sensor, with integrated Power Supply Unit, which is mounted on the

•

vessel (typically on the wheel-house) as required.

The CyScan Client Software: The CyScan Dashboard is a monitoring and control

•

application running within Microsoft Windows other computer. This provides the DP operator with status information and control of the system and the data stream being fed to the DP system. The CyScan Service Interface is used for system installation and maintenance. This replaces the Service Access function in earlier versions of the CyScan Dashboard and Console.

The CyScan Targets. Retro-reﬂectors consisting of high performance reﬂective

•

tape mounted on a ﬂat or cylindrical support, or – for longer-range capability – prism clusters.

Sensor

System

CyScan emits eye-safe infra-red light and detects the reﬂections received back from one or more targets mounted on designated structures or vessels. The range and bearing of the target(s) are accurately measured, displayed on the Dashboard screen and automatically transmitted to the vessel's DP system.

Start Up and Shut Down

Start Up

To Start CyScan Dashboard

1. Ensure that the CyScan sensor is powered on.

2. Double-click on the CyScan Dashboard icon. (Or run the CyScan Dashboard application from

Start > All Programs > Guidance Marine Ltd > CyScan > CyScan Dashboard).

3. The Dashboard display screen will appear. If the sensor is currently suspended, the main part of the screen will be greyed out. Click on the Resume button in the side bar in order for the sensor to begin scanning and for the results to be displayed on the screen. If the sensor was already scanning, any targets in view will be displayed straight away.

Shut Down

To Suspend, Exit or Disconnect

1. Click on the Guidance button in the lower left corner of the screen

This will reveal buttons in the side bar as follows: (see right).

Dashboard screen with sensor suspended Dashboard screen with sensor scanning

Suspend - Places the sensor into a ‘sleep mode’. The rotor ceases spinning and the

•

scanner tilt returns to a ﬁxed state. However, upon command from the Dashboard application, the unit will return to full operation. This mode is suitable for use when travelling between locations.

Disconnect - Ceases communications between the Dashboard and sensor and

•

causes the main part of the screen to be greyed out. Does not cause the sensor to stop spinning or tracking targets.

Suspend And Disconnect – A combination of the above two functions (Serial

•

Dashboard only).

Suspend And Exit - Places the sensor into the same ‘sleep mode’ as the suspend

•

command (discussed above) and also closes the CyScan Dashboard program.

Exit - Closes down the Dashboard without affecting the sensor.

Screen Layout (Continued)

Main Screen and Bird's Eye View (BEV)

The centre of the circular BEV represents the CyScan sensor and it shows the relative positions of the CyScan vessel and any detected reﬂections.

Vessel Outline

The length and breadth of the vessel and the offsets and orientation of the CyScan sensor within it can be conﬁgured using the CyScan Service Interface (see Installer's Guide) so that the vessel image is correctly scaled and positioned on the BEV.

Blanking Zone

The Blanking Zone is the sector within each revolution of the sensor rotor where the laser is switched off. It is typically set to correspond to the area in which the beam would strike portions of the vessel structure. The blanking zone can be adjusted using the Drag Handles, to suit different situations (See

Range Circles

The Range Circles act as a visual guide to show the distance between the CyScan vessel and the detected reﬂections. Distances are shown in metres from the CyScan sensor. Use the Zoom Control to change the scale of the display. (See page 13).

Blanking Zones on page 22).

These form an angular scale in degrees, clockwise around the circumference of the BEV. Zero is deﬁned by the bow of the vessel, or by a line between the primary and secondary targets, or by a manual alignment of vessel heading, depending upon the selected tracking mode, DP format and display coordinates.

l

12

Screen Layout (Continued)

Reflection Images

Reﬂections received by the sensor are displayed as yellow circles. For tracking you must select the reﬂection(s) that correspond to the physical target(s) to be used. During multi-target tracking, grey boxes are drawn around the selected reﬂections to indicate a strong association with the target (i.e. the system is receiving good data and is conﬁdent of the target position). A red box appears around a selected reﬂection during tracking if the system has lost sight of the target, or there is insufﬁcient data being received to use it for tracking.

Bearing and Heading Tags

These are displayed on the Radial Marker when the system is in tracking mode, to indicate the bearing of the primary (or only) target and the vessel's heading. The visibility of these two elements depends on the DP format selected and which coordinate system is being used to display the positional information (see

Data Logging Indicator

This symbol is displayed when data is being logged to disk. During a tracking operation the symbol is steady and when manual logging is in progress it ﬂashes.

Positional Display Modes on page 29).

Zoom Control

Click on the left-hand side of the control (marked '-') to zoom out of the display and on the right-hand side ('+') to zoom in.

System Status

This consists of two ﬁelds:

Primary

The primary part of the of the Main Screen. It indicates the current status of the system (e.g. running, suspended or error).

Secondary

The secondary status display is located in the lower right corner of the Main Screen (beneath the zoom function) and is normally hidden. It displays a ﬂashing message for a number of seconds in order to conﬁrm an action taken by the user, e.g. starting manual data logging. It can also display a persistent, static message if there is a communications problem.

Menu Pane

The Menu Pane, located across the bottom of the CyScan Dashboard Screen, is not always visible. It appears when one of the Tracking, Tilt or Advanced buttons near the foot of the Side Bar are pressed, which causes the Bird's Eye View (BEV) to contract towards the top of the screen. Clicking the same button for a second time causes the Menu Pane to disappear and the BEV to be restored to full size.

The Menu Pane is used to display a wide variety of information and controls, often accessed by further tabs and buttons that become available once the Menu Pane is in place.

l

16

Screen Layout (Continued)

Coordinates View

Whilst tracking is in progress, the positional coordinates and the Bird’s Eye View can be transposed, so that the coordinates are displayed in extra-large numerals on the main screen, whilst a miniature BEV is shown at the top of the side bar.

If tracking ends, the layout automatically reverts to Bird’s Eye View, but as long as Coordinates View remains selected, the main screen will again display coordinates once the next tracking operation commences.

To Select Coordinates View

This can be done in a number of ways:

1. Navigate to Advanced > Display Options > Screen Layout.

•

2. Click on the Coordinates radio button.

Click on the numerical data near the top-left corner of the screen.

•

Press F4.

•

Click on Switch To Coordinates Layout Mode in the Dashboard Hotkeys menu.

•

l

17

Tracking Information Quality

The CyScan Sensor rotates anti-clockwise. On each rotation, the sensor emits a beam of infrared laser light and analyses the position of any reﬂections that it receives.

After several rotations, the sensor is able to compare the reﬂections received on the last rotation with those received during previous rotations. This enables CyScan to recognise the reﬂections from the intended targets and to ignore any unwanted reﬂections.

Before tracking has been selected, the Data Quality and Coordinates area in the upper left corner of the screen is empty. After tracking is started, the coordinates are initially displayed in red or amber and the quality bar is partially ﬁlled with the same colour.

After a few seconds, as the scanner gathers more information, the colour changes from amber to green and more - or all - of the Quality bar is ﬁlled. This indicates that the system is reliably tracking the targets.

18

l

Display Settings

To provide ample visibility during daytime operation and to limit glare during night shifts, CyScan Dashboard offers two display settings: Day Mode and Night Mode. In either mode the brightness can be further adjusted by the Screen Brightness control.

To change day/night mode and adjust brightness:

1. Navigate to Advanced > Display Options > Display Settings.

2. Click on one of the Day / Night Mode symbols.

3. Click on the left side of the Screen Brightness control to dim the screen and on the right to make it brighter.

Alternatively, to toggle between day and night mode, use the keyboard shortcut F6 or the

Toggle Day/Night Mode button in the Dashboard Hotkeys panel.

Vessel Orientation

CyScan Dashboard supports four different layouts of the Bird’s Eye View so that the operator can choose the one which best represents his surroundings.

For instance, if the operator is facing forward when using the Dashboard, he may want the bow of the vessel in the BEV to point upwards, so that targets located on the starboard side of the vessel are shown on the right-hand side of the BEV.

To set Vessel Orientation:

1. Navigate to Advanced > Display Opons > Screen Layout.

2. Click on the vessel outline that points in the required direcon.

Blanking Zones

The Blanking Zone is used to mask a segment of the scan rotation. When the scanner passes through the blanking zone, the laser is switched off to prevent any unwanted reﬂections from being mistaken as targets.

N.B. Even if the sensor has a clear 360° view, there must be a blanking zone of at least 23°.

Generally, once the blanking zone has been set, it will not need to be changed. However, there may be occasions when it is necessary to adjust the blanking zone, for example if the target is on the opposite side of the vessel to normal.

Setting the Blanking Zone

The start and end of the zone can be set to any positions around the circle to the nearest degree, subject to the minimum and maximum sizes of the zone.

To define the Blanking Zone

1. Click one of the blanking zone handles and, holding down the left mouse button, drag to the desired position. Alternatively - on a touchscreen - touch and drag. As the handle is moved, its current position (in degrees clockwise from the vessel bow) is displayed in blue numerals outside the perimeter of the circle.

2. If required, drag the second zone handle in the same way.

3. The Apply-Cancel buttons will have popped up after step 1. Click on the Apply button to set the blanking zone, or on Cancel to restore the blanking zone to its previous state.

The blanking zone must cover at least 23° but no more than 337°.

l

22

Working with Reflections

Basic Refections Data

Reﬂections data is displayed on two panes accessed via the Tracking Button. The Reﬂections pane contains a list of reﬂections that are visible to the scanner, and the Range, Bearing and Brightness level of each:

The user is able to ﬁlter out unwanted reﬂections (see following sections) and can choose whether to include rejected reﬂections in the list by means of the Hide Rejections / Show

Rejections toggle button.

a. Filtering by Range

Allows the user to discard reﬂections that are closer than the threshold range. For example, setting the range threshold to 35m will cause any reﬂections from less than 35m away to be discarded. The range threshold can be adjusted between 5 and 70 metres by clicking on the end of the ﬁlter bar marked '+' or '-' as required. A corresponding grey circle is shown on the BEV.

b. Filtering by Reﬂection Brightness

Allows the user to reject reﬂections that are below the threshold brightness level. For example, if you set a threshold of 20%, any reﬂections that have a brightness of 20% or less will be rejected. The threshold can be adjusted between 0% and 100% (reﬂection brightness is measured as a percentage of the brightness of the light emitted by the laser).

Filtering Reflections

The Filter Reﬂections function on the Reﬂections pane allows the user to set minimum range and brightness thresholds. Any reﬂection at a shorter range than the range threshold is not included in the list of reﬂections nor displayed on the BEV. Any reﬂection with a lower brightness level than the brightness threshold is classiﬁed as a ‘reject’ in the Type column of the list of reﬂections and is represented as a red square on the BEV. This mechanism is useful when unwanted reﬂections cannot be eliminated by means of the blanking zone function alone. It can be used at any time, even during tracking.

Range Filter Bar Brightness Filter Bar

l

23

Working with Reflections (continued)

Extended Reflection Data

The Reﬂection Pulses pane contains details about the number of pulses that make up each reﬂection, and their angle of incidence.

Pulse - This column displays the number of laser pulses that have been received back from each target in the following format:

USING/BAD/TOTAL/REJECTED

For example, if the pulses column was displaying 9/1/11/1, it would indicate that CyScan was using 9 laser pulses for the position calculation, and had discarded 1 bad pulse and rejected 1 pulse out of a total of 11. In general, the larger the target the more pulses that will be returned. This value will increase as the distance to the target reduces.

Width - The Width column shows the horizontal width of each target, measured in degrees.

Lower, Middle and Upper - These columns indicate whether the scanner is pointing too low or too high in relation to the detected reﬂections. This can occur when the CyScan vessel is working close to a rig and the targets are mounted high above the scanner (see

Manually Tilting the Scanner on page 26).

Rev # - The total number of revolutions made by the scanner rotor since CyScan was last powered up or resumed.

Marker - The Marker displays the orientation of the scanner in relation to the vessel: 0° indicates that the scanner has been mounted with its information display facing the bow. 180° indicates that the scanner has been mounted with its information display facing the stern.

Pulses - The total number of pulses received during the last revolution of the scanner rotor.

Temperature - The temperature inside the scanner unit (see

Operation on page 56).

Low Temperature

High readings in either the lower or upper channels can also be caused by unwanted reﬂections and do not necessarily indicate that the scanner is pointing too low or too high in relation to the intended target

l

24

Scanner Tilt Controls

The scanner tilt mechanism automatically compensates for the pitch and roll of the vessel caused by wave motion.

Motion sensors and a tilting optics mechanism ensure that the scanning optics remain at the correct level to see the target.

Scanner Tilt Modes

The scanner can be operated in either of the following tilt modes:

Auto - The scanner tilt automatically adjusts to compensate for draught changes as

•

the vessel loads or unloads, and for gradual tidal movement. Also effective when the elevation angle of targets increases as the vessel approaches a platform.

Manual - This mode is used to manually tilt the optics to reach the target. For

•

example, when station-keeping close to a platform where the targets are mounted high up and the CyScan optics must be tilted up at them. (See

Scanner on page 26).

The current tilt mode and leveller angle (if non-zero) are displayed in the ‘Tilt Mode:’ section of the Side Bar.

To change the scanner tilt mode and leveller angle

1. Click on the Tilt button in the Side Bar.

Manually Tilting the

2. Select the required mode and click on the Apply button to conﬁrm.

3. Click on the +/- buttons to adjust the angle. The adjacent list of estimated elevation angles for visible targets helps you to arrive at the best leveller angle.

4. Click on the Apply button to conﬁrm your changes.

Scanner Tilt Controls (Continued)

Manually Tilting the Scanner

The Manual mode is used to tilt the scanner optics to a user-deﬁned angle so that the centre of the fanned beam is pointing at the target. This may be necessary when the CyScan Vessel is close to a platform and the targets are positioned above the sensor.

Upper Channel

Middle Channel

Lower Channel

Beam Spread

The CyScan optical receiver is divided into three vertical channels: Lower, Middle and Upper. The proportion of beam signal being received in each channel is used to determine

the correct angle to set the optics.

If one of the reﬂections in the list is selected, its elevation relative to the horizontal is shown by the position of the yellow target symbol on the right-hand side of the Leveller Graphic. The blue line represents the laser beam, and this moves as the +/- buttons are clicked. When the laser line points to the centre of the target symbol, this indicates that the leveller angle is ideal for the selected target

Scanner tilted up and pointing at a target mounted higher than the sensor.

Spirit Level

The Spirit Level control, on the left hand side of the Tilt pane, displays the roll and pitch of the vessel as measured by the Vertical Reference Unit within CyScan. The graphical display represents the roll and pitch angles in the same manner as a bull’s eye spirit level. The current values are displayed in text at the bottom of the control. A ship outline is shown in the background to indicate orientation relative to the vessel.

Single and Multi-Target Tracking

This section explains the different types of target tracking that can be performed using the CyScan Dashboard, and how to conﬁgure them. It does not provide advice on how to set up a tracking operation for a speciﬁc DP system or application.

The information contained in this section is for general guidance only. This section does not provide an exhaustive explanation of target tracking using CyScan, nor does it form the basis of a contract. Implementation of the material covered in this section will vary according to the type of DP system used in conjunction with the CyScan system. The use of, or reliance on, anything in this section is therefore entirely at the user’s own risk and should only be undertaken after assessment of its accuracy, completeness and suitability for the proposed use.

Introduction to Single and Multi-Target Tracking

The CyScan system can track either a single target or multiple targets:

Single-Target Tracking

During Single-Target Tracking, only one target is used.

Single-Target Tracking is quick and easy to use, but has the following limitations:

Tracking stability is affected if the target reﬂection is temporarily lost,

•

as there is no redundancy.

If the true target reﬂection is obscured by vessel operations,

•

there is a possibility that the sensor track could jump to another reﬂection.

Relative vessel heading cannot be calculated.

•

Multi-Target Tracking

In Multi-Target Mode, CyScan uses between two and ﬁve targets. Guidance Marine recommends using a minimum of three targets. Multi-target tracking has the following advantages compared to single-target tracking:

Improved tracking stability.

•

Increased immunity to false reﬂections.

•

Redundancy allows tracking to continue even if a target is temporarily lost.

•

The vessel’s heading in relation to the Multi-Target Group can be calculated.

•

To Start Tracking

For Single-Target Mode

1. Click on the required target reﬂection on the Bird’s Eye View. It changes to the selected

state (with the red dash around the outside and number “1” superimposed).

2. Click on the Apply button to conﬁrm and begin tracking.

For Multi-Target Mode

1. Select a minimum of two and a maximum of ﬁve target reﬂections (see Selecting

Targets for Multi-Target Tracking on page 31). An ordinal number will be

superimposed on each as they are clicked.

2. Click on the Apply button to conﬁrm and begin tracking.

N.B. Once a target has been selected, it can be deselected by clicking on it a second time. Deselecting a target may lead to the automatic re-ordering of other selected targets.

To Stop Tracking

Whilst tracking is in progress, a Stop button is embedded in the Tracking button on the Side Bar.

1. Click on the Stop button.

2. Click on the Apply button to conﬁrm.

l

28

Positional Display Modes

The relative positions of the CyScan vessel and single or multiple targets can be expressed either as Range and Bearing values, or as 'x' and 'y' positions on a rectangular coordinate frame.

Coordinate axes are only displayed if the DP feed format is set to either NMEA0183P or NMEA0183R.

CyScan can also display Range and Bearing data when using these formats, if required.

DP Mode Tracking Type Coordinate Axes

NMEA0183P (Primary)

NMEA0183R (Raw)

All other DP modes display Range and Bearing data only.

When using a DP message format for which more than one display mode is supported, select the required mode by clicking the appropriate tab above the Data Quality area:

Single-Target

Bow and Starboard Axes

Multi-Target

Single-Target Bow and Starboard Axes

Multi-Target A and B Axes

Range & Bearing

Range and Bearing mode displays the distance and the bearing of the primary (or only) target from the sensor. The radial markers around the outside of the BEV are zeroed in line with the vessel bow and a magenta tag marks the bearing which is the angle of the target clockwise from the bow.

In the case of multi-target tracking, there is also a heading axis. This always passes through the primary target and by default it points through the secondary target, although it can be realigned if required (see

Compass on page 40). A purple tag represents the heading, which is the angle of the

vessel bow clockwise from the heading axis.

Aligning Multi-Target Heading with the Ship’s

l

29

Positional Display Modes (Continued)

Bow and Starboard Axes

This mode is available for single-target tracking, and for multi-target tracking where the DP feed messages are sent in NMEA0183P (primary) format.

In this mode, the position of the sensor vessel is expressed in metres from the target along Bow (B) and Starboard (S) axes which have their origin at the primary (or only) target. The B and S coordinate axes are always parallel with the vessel's own axes.

For multi-target tracking, the vessel’s relative heading is based upon a third axis passing through the primary target. By default, the heading axis is drawn between targets 1 and 2 but can be realigned if required. The radial markers around the outside of the BEV are zeroed in the same direction as the heading axis. The purple heading tag is aligned with the vessel bow, at the point on the scale that shows the angle of the bow clockwise from the heading axis.

Bow and Starboard Axes

A and B Axes (A Pos and B Pos)

This mode is only available for multi-target tracking where the DP feed messages are sent in NMEA0183R (raw) format.

In this mode, the position of the sensor vessel is expressed in metres from the target along A and B axes which have their origin at the primary target.

The axes are initially aligned with the multi-target group, with the A axis passing through the secondary target. The vessel's relative heading is measured clockwise from the A axis. If required, the axes can be manually realigned to correspond with the DP system or another sensor's coordinate axes.

The radial markers around the outside of the BEV are zeroed in the same direction as the A axis, which acts as the heading axis. The purple heading tag is aligned with the vessel bow, at the point on the scale that shows the angle of the bow clockwise from the A axis.

Selecting Targets for Multi-Target Tracking

The terminology in this section relates to a DP Message Format of NMEA 0183R (Raw), i.e. A and B coordinate axes instead of Bow and Starboard.

Selecting Reflections

When you select a reﬂection as a target, make sure that it corresponds to the actual target that you wish to track against. You can select up to 5 reﬂections to form a multi-target group.

The ﬁrst reﬂection that you select (target 1) becomes the primary target, which forms the origin of the A and B coordinate axes.

The second reﬂection that you select (target 2) sets the default orientation of the A and B coordinate axes. If there are more than 2 reﬂections, select the reﬂection furthest away from target 1. (See

A further 3 reﬂections (targets 3, 4 and 5) can be added to give redundancy to the group if targets 1 or 2 are temporarily lost or obscured.

If more targets are mounted on the rig, then the superﬂuous ones should be physically removed and not just omitted from the multi-target group.

CyScan tracks targets more accurately when multiple targets are spaced asymmetrically (see right). If the targets are not spaced asymmetrically, it is better to operate with fewer (i.e. 2) targets.

Target Selection Order on page 32).

Axis Orientation and Vessel Heading

Target Orientation in Respect to Axis A

The orientation of the reﬂective surface of the targets is measured clockwise from the origin of the A axis to the perpendicular of a line passing through targets 1 and 2.

The default orientation value depends on the relative positions of the targets:

If target 1 is on the left when viewed from the CyScan vessel,

•

the default target orientation value is 90°.

If target 1 is on the right when viewed from the CyScan vessel,

Axis Orientation and Vessel Heading (Continued)

Vessel Heading

Vessel Heading is measured clockwise from the origin of the A axis to the CyScan vessel’s centre-line. The vessel’s relative heading value depends on the orientation of the coordinate axes. Changing the orientation of the A axis also changes the vessel’s relative heading.

In the examples below, the vessel’s heading relative to the targets remains constant. However, the system measures different heading values according to the different orientation of the A and B coordinate axes.

(The reported ‘A Pos’ and ‘B Pos’ values will also change, as the coordinate axes from which they are measured have moved.)

Rotational Offsets

Some DP systems and applications may require the A and B coordinate axes to be rotated to match a different heading. For example, to line-up with the DP System’s own coordinate axes, the axes of another sensor, the vessel’s gyrocompass, or any other heading value.

When the axis orientation is adjusted manually, both the A and B axes are rotated about their origin in the centre of target 1.

Vessel heading is measured in a clockwise direction from the A axis, so changing the orientation of the coordinate axes also changes the vessel’s relative heading value.

The orientation of the A and B coordinate axes can be adjusted by aligning the multi-target group to a given vessel heading.

Aligning Multi-Target Heading with the Ship’s Compass

If you require CyScan to produce a heading based on geographic North rather than on the orientation of the primary and secondary targets, follow the instructions below.

These cause the A and B axes and position coordinates to be recalculated accordingly.

The heading and position coordinate data sent to the DP system will change instantly when you conﬁrm the new alignment.

You must deselect the CyScan sensor at the DP Console BEFORE commencing this operation.

To Align Multi-Target Heading with the Ship’s Compass:

Whilst multi-target tracking is in progress using an NMEA DP message format:

1. Navigate to Advanced > Align Heading.

2. Either key the required heading value into the numerical entry box and click Preview, or else move the red compass needle to the required position, either by clicking and dragging it or by repeatedly clicking the small +/- buttons.

3. Click on the Apply button to conﬁrm.

Drag the compass needle to the required heading.

Multi-Dashboard (Ethernet) CyScan Systems

This section contains the following pages:

Note that a CyScan system running with Serial communications supports only a single Dashboard, and whenever this is running and connected to the sensor, it is effectively in command mode.

l

41

CyScan Ethernet Dashboard - Monitoring Mode

CyScan, when conﬁgured to run with Ethernet communications, supports multiple Dashboards running simultaneously on the same system. No more than one of these can be in Command mode at any given time; the others are in Monitoring mode.

When the Dashboard is running in Monitoring mode, the controls relating to the Dashboard itself will be active, but those relating to the CyScan sensor will be disabled. A Monitoring Dashboard displays the same reﬂections and positional data as the Command Dashboard, although it is updated at a reduced rate (every 3-4 seconds instead of every second). It cannot initiate or stop tracking operations, nor alter the power control, reﬂection ﬁltering nor tilt settings.

When a Dashboard running with Ethernet is launched, it defaults to Monitoring mode if the sensor is already spinning.

Examples of inactive controls in Monitoring Mode

To switch a Dashboard from In Command mode to Monitoring mode:

1. Click on the Guidance button.

2. Click on the Relinquish Command button.

l

42

CyScan Ethernet Dashboard - In Command Mode

When the CyScan Dashboard is running in Command mode all control functions are available. Any changes made to the tracking or sensor-related settings at the In Command Dashboard will be visible on the screens of the Monitoring Dashboards. On the other hand, display options such as Screen Brightness or Zoom level can be set differently on each individual Dashboard, whether it is Monitoring or In Command.

When the In Command Dashboard is used to suspend the CyScan sensor, a message will appear on the screens of the Monitoring Dashboards indicating that the system is suspended. The same message is displayed if a Dashboard is opened whilst the sensor is suspended (See

In this state, clicking the Resume button on any Dashboard will automatically put that Dashboard In Command. Clicking Exit will close that individual Dashboard only.

Whenever the system is running, a Monitoring Dashboard can be promoted to In Command as shown on the right.

Start Up and Shut Down on page 10).

Examples of controls available only In Command mode

To switch a Dashboard from Monitoring mode to In Command mode:

1. Click the Guidance button.

2. Click on the Take Command button.

If there was already an In Command Dashboard in the system this will automatically switch to Monitoring mode when a different Dashboard is switched to In Command mode.

If tracking is in progress, data logging will cease on the previously In Command Dashboard and commence on the new In Command Dashboard.

Targets-Installation and Position

CyScan can operate successfully with ﬂat, cylindrical or prism targets. These can be bought online from www.marine.direct.

Flat Targets

Flat targets are generally attached to rigid structures such as metal stanchions using steel bands.

2 metre tall ﬂat targets can typically be seen at up to 400 metres in ideal conditions. Shorter 1 metre tall ﬂat targets are visible at up to 250 metres when viewed straight on.

Part number: 20-0031-0

(2m x 350mm ﬂat reﬂector including stainless steel bands)

Cylindrical Targets

Cylindrical targets can be used up to approximately 300 metres. They can be hung over the side of the structure/vessel and secured at either end.

Part number: 20-0078-0-B

(1.9m cylindrical reﬂector)

Prism Targets

Prism clusters with multiple 6cm elements for extended range operations. Variable conﬁgurations allow for optimisation of the visible reﬂection, visible reﬂection level or reﬂected power. A ﬁxed layout rugged version includes a robust housing, brightly-coloured for easy identiﬁcation.

Targets-Installation and Position (Continued)

Target Installation

Key to the operation of the CyScan system is the correct installation of targets. Please follow the guidelines given below when installing targets on the structure/vessel.

Once the targets are installed, their relative positions can be automatically surveyed by the system.

Installation Tips

Targets should be placed in positions where the sensor can see them while the vessel

•

is within the expected working area. Consider vertical position as well as horizontal.

Flat targets should not be placed too far along the structure/vessel from the expected

•

working area as this can reduce the viewing angle for close operations.

The sensor beam should not strike a ﬂat target at an angle of more than 45 degrees to

•

the target surface.

Cylindrical targets can be viewed from any angle equally well.

•

Optimum Spacing for Multiple Targets

Targets should be positioned with unequal spacing between them – this helps the

•

system to distinguish between speciﬁc targets. For example, with a typical mooring distance of 40-80m using three targets, suitable spacings between the targets would be 10m and 20m – giving a total spread of 30m.

Targets should be placed no closer than 5m together. Ideally they should be placed

•

10m or more apart.



Targets are asymmetrically spaced,



thus making it easier for the CyScan system to assess which reﬂection corresponds to a particular target.

Targets are too close together and



have even spacings. This makes it more difﬁcult for the CyScan system to differentiate them.

l

55

Low Temperature Operation

Introduction

The CyScan sensor is a precision electromechanical device with hardware components that, of necessity, are mounted in an external position on a vessel’s superstructure. It is recognised that industrial marine operations may subject these components to harsh environments, including low temperature.

The CyScan hardware complies with the requirements of IEC 60068-2-1 and is able to operate for prolonged periods at temperatures down to – 25°C provided that certain operating conditions are maintained.

If there is a requirement for CyScan to operate at temperatures below -25°C, contact Guidance Marine.

Operating Conditions

The following recommendations are made for low temperature use:

If it is necessary for the system to be switched on after a prolonged period at

•

temperatures below 5°C (and down to – 25°C) the sensor will warm itself, but will require some time to reach optimum operating condition.

If the unit is switched on after a period at temperatures between -15 to -25°C it will

•

not communicate with the Dashboard and the rotor will not rotate until the internal temperature of the base unit rises above -15°C.

When the system is not in use (i.e. un-powered or suspended) the sensor should

•

be protected by means of a suitable insulating and protective cover to prevent the external build-up of ice.

For operation below – 25°C additional forced air heating must be provided. Do not use exhaust emissions as these contain particulates which will degrade the optics.

Technical Considerations

The CyScan sensor uses a sophisticated rotating infra-red laser range-ﬁnder to

•

accurately measure the distance and bearing to retro-reﬂective targets that are placed at speciﬁc locations in the working area. Movement sensors allow mechanically driven optics to compensate for vessel motion due to wave action. The internal mechanism may become disabled if it is allowed to cool in a low temperature environment.

A safety interlock prevents activation of the range-ﬁnder laser if the scanner rotor head

•

stops or is prevented from rotating by ice build-up.

View of the retro-reﬂective targets will be obscured by a build-up of ice on either the

•

optical window of the scanner or the surface of the targets (N.B. ice has poor reﬂective properties at the infra-red frequency used by CyScan).

l

56

Using the On Screen Keyboard

In order to accommodate systems without keyboards, CyScan Dashboard provides an onscreen Keyboard (OSK) option. This enables text to be input using only a mouse pointer or touch screen.

To enable the on-screen keyboard

If, during installation, you indicated that the Dashboard would be used with a touch screen, the OSK will already be enabled.

Otherwise, click F11 or the Enable On Screen Keyboard button in the Dashboard Hotkeys menu.

To use the on-screen keyboard

Simply click on any text entry ﬁeld and the OSK will pop-up ready for use:

In the case of a numerical ﬁeld, the OSK is restricted to the appropriate keys:

When you have ﬁnished using the OSK, proceed to the next relevant action (e.g. clicking on the Apply button), or else click on a different part of the screen, and the OSK will disappear.

Click on the necessary keys on the on-screen keyboard using your mouse or by tapping the touch screen.

l

57

Working with Alarms

During operation, the CyScan system produces an audit trail of event messages. These range in increasing order of severity from: Information, Warning, and Error to Fatal. As these alarms are raised, the Dashboard lists them within the Alarms pane.

Click on any alarm to display details about it in the right-hand section of the Alarm pane:

The severity and current state of an alarm are reﬂected in its colour and shape:

Information—grey symbols

•

Warning—orange symbols

•

Error—red symbols

•

Fatal—red symbols

•

The arrowhead symbol indicates that an alarm condition is persisting; an alarm in this state will show a Start time but not a Stop time.

The square symbol means that the alarm condition no longer exists, therefore the alarm will show both Start and Stop times.

The pause symbol indicates an instantaneous alarm. In this case, the Start and Stop times are identical.

When an Error or Fatal alarm is raised, the Alarms pane is opened automatically and the Advanced button in the side bar is shaded red as in the example above. If the pane is closed, the Advanced button returns to its normal grey shading.

Additionally, after a Fatal alarm has been raised, close the Dashboard, power down the sensor and restart the system.

Filtering Alarms
