4. Sector/Zone: Properties
Set of properties:
Name
Size and position (fixed)
Mode for a unique result
Alarm threshold
Output interface for the result (digital/analog hardware output module, DDE interface, etc.)
Can overlap partially or completely
Number of sectors/zones supported by the software is practically unlimited (number of sectors/zones supported by the scanner itself is limited!)

5. Sector: Positioning
Fixed position for a sector during the runtime software
Sector position defined via left and right edge

6. Zone: Positioning
Fixed position for a zone during the runtime software
Zone position defined via 4 edges  
Right-angled rectangle
Convex rectangle
Concave rectangle

7. Zone: Positioning

8. Zone: Positioning
Comfortable positioning of zones under the Configurator’s graphical board
Record a snapshot
Load the snapshot into the graphical board
Overlay the zone grid like desired

10. Sector/Zone: Modes
The sector/zone mode provides one unique result – in the most cases a temperature value
Does one really need these many modes?

11. Sector/Zone: Modes Maximum, Average, Minimum 80 90 70 Sector
Maximum: 90°C
Average: 80°C
Minimum: 70°C
Maximum  detecting of hot spots
Average  controlling of process devices
Minimum  detecting of temperature holes

12. Sector/Zone: Modes Case Study
Customer runs in the averaging mode to control the process
Temperature changes due to seasonal fluctuations
How can one eliminate ambient temperature changes?

13. Sector/Zone: Modes Maximum – Average, Average – Minimum 80 90 70 70 80
Maximum – Average = 90°C – 80°C = 10°C
Process = 80°C
Temperature differences represent the sector only – no need for readjustments! 70 80 60
Sector
Maximum – Average = 80°C – 70°C = 10°C
-10°C
Process = 70°C
The given modes provide relative temperature differences compensating absolute temperature changes!

14. Sector/Zone: Modes Greater Value: (Max – Avg) or (Avg – Min) 80 90 75
Maximum – Average = 90°C – 80°C = 10°C
Greater Value (10°C) or (5°C) = 10°C
Average – Minimum = 80°C – 75°C = 5°C
The mode provides relative temperature differences independent from the direction of deviation!

15. Sector/Zone: Modes Case Study
Monitoring of glue tracks on a supporting material finally used for nappies
Temperatures close to ambient  quite noisy signals
Glue tracks

16. Sector/Zone: Modes Maximum – Minimum 30 24 26 28 Sector
Maximum – Minimum = 30°C – 24°C = 6°C
Maximum – Minimum maximizes the sector result especially for noisy measurements!

17. Sector/Zone: Modes … an aspect in regard to averaging

Does the archer hit the target in the average?

18. Sector/Zone: Modes Standard Deviation 28 32 26 34
Standard Deviation = 2°C
4°C
Standard Deviation = 4°C
Average 30°C
Average 30°C
The standard variation shows how much variation exists from the average!

19. Sector/Zone: Modes Case Study
Monitoring the operator’s loading efficiency on a tempering oven

20. Sector/Zone: Modes Covered Area
… configure a zone completely covering the whole snapshot 32 87 85 30 89 88 31 28 29
Threshold: 80°C
Covered Area: 45%
The Covered Area counts the pixel above a threshold and relates it to the total number of pixels!

A too steep temperature increase indicates a wrong alignment of the roller

22. Gradient= ∆ Temp Length
Sector/Zone: Modes
Gradient, positive gradient, negative gradient
… represents the steepness and the direction of a slope

Alarm Threshold=15 °C cm
100°C 10cm =10 °C cm
200°C 10cm =20 °C cm
Gradient: detecting of rising or falling slopes
Positive gradient: detecting of rising slopes only
Negative gradient: detecting of falling slopes only

A simple sector running in Maximum mode can not do the job because it calculates the result for each line separately!

24. Sector/Zone: Modes Max of Area
Area building: adjacent pixel defined by a threshold
Pixel counting: alarm threshold via number of adjacent pixel
Sector

Line 3 75 82 85 79 83 81 73 70 78

Area threshold: 80°C
No alarm! (4 pixel)
Alarm threshold = 5 pixel
Max of Area monitors for bigger hot spots over multiple lines in continuous running applications!

25. Sector/Zone: Modes Snapshot Counter
Zone result is increased by 1 with each new snapshot
Zone result is a number and not a temperature value any longer
Mode can be used as life indicator (“heart beat”) for the remote control system

29. Automatic Sector Automatic Sector is dynamically positioned via:
a) Gradient (temp. change over length)
b) Temperature threshold

30. Automatic Sector Automatic Sector detects:
a) running/waving edges (velocity for the edge position)
b) temperature gaps (threshold related to the sector average)

31. Automatic Sector For standard sector modes use subsectors
Automatic Sector width not constant  give the subsector width percentaged
Subsectors represent separated rollers
