Transcript

  • 1. An investment in knowledge always pays the best interest. Benjamin Franklin APM 3DLevelScanner ™ Changing the market from level to volume Inventory Means Money Mordi Perl, EMEA Executive Sales Director Innovating and Pioneering 3D True Volume Measurement of Solid Materials in Silos and Open Bins
  • 2. Moving from level to volume measurement of solids
    • Level measurement, good for liquids, not relevant for solids
    • Traditional level measurement devices only measure the distance between the device and one single point on the surface.
    May 2011 APM Annual International Partners Conference
  • 3. Single-point measurement technologies May 2011 APM Annual International Partners Conference
  • 4. Replacing estimation with accurate volume measurements
    • APM innovates by:
      • Measuring multiple points along the surface of solids stored in practically any kind of container
      • Calculating true volume of materials stored
      • Providing 3D visualizations of a container’s contents
      • Filtering out false echoes
    • Improved accuracy – saves money
      • Enables decision-makers to use APM measurements and integrate them into their MRP (material requirement planning)
    May 2011 APM Annual International Partners Conference
  • 5. How improved accuracy saves money
    • Decreases extra safety stocks
    • Lowers costs by ordering materials only when they are needed
    • Eliminates production stoppages caused by lack of materials in process
    • Avoids overflow and its consequences: materials loss, environmental damage
    • Optimizes the right mix of materials used in the production process
    • Reduces required storage (volume) capacity
    May 2011 APM Annual International Partners Conference
  • 6. APM technology building blocks Physics Mathematics Electronics Digital Signal Processing
  • 7. Scanner position, acoustic waves reflection
    • Positioning the 3DLevelScanner to see most of the material most of the time
    • Transmitted acoustic waves are distributed, and echoes are received, in orbits.
    May 2011 APM Annual International Partners Conference
  • 8. Measuring distance in a 3D environment
    • Distance (R) = velocity times the time an acoustic wave travels R = Velocity x (time/2)
    • A stop watch starts at beginning of transmission and stops when echo is received
    • Challenge : to find the right echo as well as the direction from which it arrives.
    z y x z 1 Speed of sound in the air = 1,236 Km/H (343 m/sec) R = radial distance May 2011 APM Annual International Partners Conference
  • 9. Measuring distance in a 3D environment
    • Calculating distance in a 3D environment: x - y - z R Distance : absolute radial (diagonal) distance measured from the top of the transducer case to any point on the surface Z Distance (x, y, z coordinates): straight down distance from a given point on the surface to the top of the transducer case at a given point x,y offset on the roof
    z y x 0.0.0 y 1 x 1 z 1 K R x i, y i x i , y i, z i May 2011 APM Annual International Partners Conference
  • 10. Measuring distance in a 3D environment Each APM scanner uses 3 antennas
    • Each antenna transmits acoustic waves and receives echoes coming from all directions.
    • Echoes coming from the walls of the silo are faulty and must be filtered out.
    Reference Point 0,0,0 R 1 R 2 R 3
  • 11. 3 antennas – 3 different measurements of a single point
    • Guarantees knowing the precise x-y-z location of each point
    • Since scanner is located in a specified position (x i , y i , z i ) on the silo roof, all measurements must be normalized for the true, central reference point, 0.0.0.
    May 2011 APM Annual International Partners Conference
  • 12. APM technology building blocks Physics Mathematics Electronics Digital Signal Processing
  • 13. Calculating volume in 3D environment
    • APM knows how to accurately measure distance to any point.
    • APM measures multiple points.
    • Result: accurate volume measurements of the space above the material surface.
    Material volume = silo volume – space volume May 2011 APM Annual International Partners Conference
  • 14. Prerequisites for accurate measurements
    • Precise silo, bin or container dimensions
    • Precise location of the APM scanner
    • APM’s Locator software automatically normalizes system to incorporate true reference point in all calculations.
    ( 0.0.0.) ∆ ◘ ( x i y i z i ) 90° APM scanner location and orientation May 2011 APM Annual International Partners Conference
  • 15. APM technology building blocks Physics Mathematics Electronics Digital Signal Processing
  • 16. Electronics - Challenges
    • Generate a strong and recognizable signal
    • Generate strong SNR (signal-to-noise ratio)
    • Echo identification Each echo has a unique digital signature that can be matched with the transmitted signal.
    • Echo filtering
    • Match of the echo signature with that of the one transmitted stops the “timer” and records the time.
    Energy Time May 2011 APM Annual International Partners Conference
  • 17. Electronics – Challenges Acoustic wave attenuation
    • Harsh, dusty and humid environments attenuate the strength of acoustic waves.
    • APM’s low frequency signals – at 3-4 KHz – bypass this problem while losing only 2-3 dB.
    Signal attenuation due to dust/moisture concentration in the air May 2011 APM Annual International Partners Conference
  • 18. Electronics – Challenges Acoustic wave attenuation
    • Harsh, dusty and humid environments attenuate the strength of acoustic waves.
    • APM’s low frequency signals – at 3-4 KHz – bypass this problem while losing only 2-3 dB.

  • 19. APM technology building blocks Physics Mathematics Electronics Digital Signal Processing
  • 20. Digital Signal Processing
    • APM’s patented algorithms filter out false or irrelevant echoes using many specified parameters, key among them:
      • Direction of arrival
      • Time of arrival of the echo
    May 2011 APM Annual International Partners Conference

  • 28. Real-life materials surface mapping
    • Large brewery
    • Huge quantities of grain stored in very tall, very wide silos
    • Constantly challenged by significant surface irregularities of stored materials
    May 2011 APM Annual International Partners Conference
  • 29. 3D visualization during empty cycle # 1
    • Inset photo shows bin contents at time of measurement.
    • Single-point measurement devices would not reflect such irregularity in this material surface.
    Calculated mass = actual weight May 2011 APM Annual International Partners Conference
  • 30. 3D visualization during empty cycle # 2
    • 3D visualization reflects consistency with taped measurements.

  • 34. Converting volume to weight
    • Material density is measured in tons/m 3
      • Bulk density differs from normal density
      • Bulk density values can be built into scanner’s memory
    May 2011 APM Annual International Partners Conference
  • 35. Converting volume to weight
    • APM scanners calculate weight based on bulk density
      • Weight = bulk density x volume
      • Weight is calculated during material filling and empting
      • Inventory value can be calculated at any given time
