Information Paper - Eyes for automated container- and process cranes

Published in News

 

(LASE GmbH) (Wesel, 06.03.2019)

The wave of automation keeps moving! More and more operators of sea- and intermodal ports or in steel plants have started automating their cranes entirely. In order to perform this task without humans, the cranes need eyes by applying 2D- and 3D laser scanners. These sensors and an analogue evaluation of the measurement data by application-specific software allow an automated transshipment of containers, coils, slabs or even scrap metal. Different examples about the functionality of the measurement systems and solutions are shown in this paper.

Technology Area - 2D- and 3D laser scanners

The main topic within this paper is called “The eyes for automated container- and process cranes”, which is based on two- and three-dimensional laser technology. It depends on the individual application, if the measurement of the objects is undertaken two- or three-dimensionally. A 2D laser scanner consists of a laser source and a turning mirror, which deflects the laser beam by 90°. The combination of laser distance measurement and the position (angle) of the deflection mirror creates a two-dimensional image. If such a 2D laser scanner is rotated in a further axis by using a swivel plate, even a three-dimensional image is created.

Application Area - Container Transshipment

One of the main field of application within the business of LASE is the measurement of objects and positions at crane systems in huge sea ports world-wide. Because of the fact that many processes are performance-driven and subjected to high pressure of time and efficiency, the use of laser-based systems offers many advantages. In the field of automated container transshipment the interfaces between all different machines need to be considered as well as the container handling in the interface between horizontal and vertical transportation.

Automatic 3D laser measurement system for automated car parking solution

Published in News

 

Automatic 3D laser measurement system for automated parking solution in car park helps to pack the cars with a high density

(LASE GmbH) (Wesel, 13.08.2018)

The application called LaseCPS (Car Park System) has been installed in a highly innovative automated car park, where it was demanded to park cars in a minimum space and where cars are moved to their parking spaces fully automated. By the utilization of 2D and 3D laser scanners the cars are measured in transfer cabins, in order to know their position and dimensions as well as to check, if there are still people in the cabin. After the measurements a lifting mechanism lowers the whole platform and transports the car to its parking place.

LASE has commissioned a combined 2D and 3D laser measurement system for automatic parking in an automated car park where it makes a significant contribution to pack the cars as dent as possible. Car drivers only need to drive their car into a cabin with a hoist platform and to check in at the ticket machine. After leaving the cabin and check-in the door shuts and the combined laser measurement system measures the car three-dimensionally and checks, if no people are still remain in the cabin. After measuring the car can be lowered and lifted to its parking place.

The installed system, a combined hard- and software solution by LASE called LaseCPS (Car Park System), is a laser measurement system working with two 3D laser scanners from the LASE 3000D-C1-224 Series, which are installed in the front left and rear right corners of the parking cabin. Another two 2D laser scanners are mounted in the two other remaining corners of the cabin. Furthermore the solution consists of a software application core with two different functions, where the cars both will be detected in 2D and where the dimension of the cars is detected in 3D. The first function, the so called “Discovery Mode”, describes the guidance of the car while driving into the parking cabin. The car must be positioned on the hoist platform and has a specific shifting system, where poorly parked cars can be corrected in their position with a maximum shifting range of 200 mm. In case of reaching a determined “safety region” on the hoist platform, a robot lifts the car by the wheels and transfers it to the parking space.

The second function is the 3D laser measurement process, which generates highly accurate 3D measurement data of the car in all dimensions. When the driver has left the car and finished at the ticket machine, the car is measured. All measurement data are transferred by an Ethernet TCP/IP interface: X/Y-Position (front, back, right, left), width, height, length, degree of misalignment as well as the max. dimension around the car to the car park control system.

For commissioning and maintenance purpose the data are visualized in a 3D point cloud that is also surrounded by an algorithmically based cuboid resp. bounding box to show the maximum dimension of the car. This information is also used to compare it with the max. values due to restrictions of the car dimensions. Nevertheless also black and white or dry and wet cars do not disturb the measurement results, so that the dimension of the cars is still measured accurately.

LaseAYC - Automatic Yard Crane

Published in Port Logistics

The application LaseAYC - Automatic Yard Crane is built to ensure a fully automated container handling in ASC stacking yards and supports semi-automatic truck handling in transfer areas.

System features and benefits:

  • Container position and skew measurement for accurate picking and stacking
  • Collision free lowering of spreader/load into the slot
  • Collision prevention during traveling with trolley in operation and adjacent bays
  • Gentle container handling by soft landings and less spreader wear
  • Stack verifi cation (to align stack database with present layout)
  • High precision measurement system
  • Position measurement of trucks / trailers / AGVs and containers in transfer areas
  • Applicable for ASCs (aRMGs) and aRTGs

Short description:

The measurement system consists of two 3D laser scanners from the LASE 3000D-Series. Both 3D-Units are installed at a distance of approximately 2,9 metres on the trolley of an automatic stacking crane in order to measure containers, trailers or AGVs threedimensionally.
This measurement system for automated container handling and the operation in ASC yards can be divided into four functions. Firstly it recognises the top edges of the container in order to perform highly accurate pick-and-drop tasks for the landing of loaded or empty spreaders. Then it also detects misplaced containers within the clearance zone.
Furthermore it is able to detect the gap between two twentyfoot containers on terminal chassis before the pick-up operation. Recently the application LaseAYC undertakes a position verification after dropping a container in its cell.

LaseAVP - Automatic Vehicle Positioning

Published in Port Logistics

The LaseAVP -Automatic Positioning Vehicle- measurement system is designed for STS-Crane operations for an efficient workflow in container handling while loading and unloading operations of vessels.

Short description:

A 3D laser scanner from the LASE 3000D-C2-11x Series is mounted at the portal girder centrally above the lanes, whose projected scan plane detects AGVs in the chosen operation lane. When an AGV drives to the crane position the laser-based measurement system verifi es, if an AGV is present at this position or not.
In for example semi-automatic operations, an AGV receives a position where it has to drive to carry or fetch a container (or two 20ft containers in twin-mode operation). After arriving, the crane PLC triggers the LASE system to verify the exact position and to calculate the skew of a free slot or load on the AGV. For the further process of loading or unloading the system measures, if the AGV stands in a centric position under the crane trolley. The values for a centric position have a specifi c tolerance range and allow non-stop loading operations.

The application is able to position AGVs for all common container types, e.g. 20ft, 40ft and 45ft and is also applicable for twin-mode spreader operations under STS-Cranes.

Fall pipe and bulk measurements on Jan De Nuls "Subsea Rock Installation Vessel"

Published in News

While the Bavarians are happy about winning the Triple, LASE installs even FOUR applications on one vessel! Dredging specialist and operator Jan De Nul utilizes laser scan and bulk measurement solutions by LASE for the Joseph Plateau - a "Subsea Rock Installation Vessel".

The world leader in dredging works, land reclamation and cable- or pipelaying on the global oceans orders four different measurement systems for its latest ship Joseph Plateau. Our proven laser technology is used on a 191 m long vessel for precise rock dumping in a depth of up to 2.000 m for the protection and stabilization of subsea pipelines. The system for the assembly of the fall pipe is extremely advanced and operates fully automatically. Due to the repeated successful collaboration with the company Jan De Nul, LASE was able to distinguish oneself in the area of intelligent laser measuring technology through its expertise in this huge project.


The complete turnkey solutions are divided into the following four applications:

1. LaseFPM - Fall Pipe Position Measurement  

2. LaseFDM - Fall Pipe Distance Measurement

3. LaseBVB - Bulk Volume Bunker

4. LaseBPC - Bulk Profile Conveyor


 

1. LaseFPM - Fall Pipe Position Measurement

On this special vessel fall pipes are used for covering undersea cables with filling material which are stuffed on board. These fall pipe consists of several single pieces which are put into each other by a robot.  Due to the state of the sea the fall pipe moves in a scope of about 2 m. For the assembly of the fall pipe it is important to determine relative position between the pipe in the water and the next pipe which has to be attached. The position will be profiled and detected in an average time of 12 msec with an accuracy of +/- 10 mm at a distance of about 5 m.

2. LaseFDM - Fall Pipe Distance Measurement

The second fall pipe measurement system was created to determinate the distance of a top-flange and the bottom-flange of a new pipe from a pipe string to reduce the impact at contact. For the mounting operation four laser scanners have to be installed which are also able to detect the vertical scan area at rough sea and the resulting vibrations of the pipe. In the case of dismounting only one laser scanner needs to be used due to a higher position of the pipe removal. With a pipe diameter of 1.000 mm the scan planes are in a distance of 800 mm to each other. In total the hardware equipment in this application consists of five 2D-scanners and one specific LASE processing unit for evaluation operations.

  • Exact flange distance detection out of 2D profile data
  • Applicable for mounting & dismounting operations of the fall pipe
  • Suppression of ropes & pipes inside the scan range
  • Accuracy of 50 mm for pipe distance measurements

3. LaseBVB - Bulk Volume Bunker

At this system solution out of the bulk measurement range, four 3D laser scanners are installed above both bunkers. At each bunker two scanners are „looking“ down on the bunker and scan its volume and profile. Out of the raw data a 3-dimensional image of both bunker profiles will be developed and compared to a so called „0-profile“ which was taken during the commissioning at the beginning. Out of the obtained data from the LASE CEWS application the software calculates the profiles and the volumes of both bunkers parallel and precise. Additionally it is also possible to extract mechanical parts (e.g. excavators in the middle of the bunker) from the scan/profile data due to special filter technology. Because of the accurate volume measurement a continuous inventory can be processed and provides a basis for material disposal.

4. LaseBPC - Bulk Profile Conveyor

In this application out of our Bulk Logistics range up to four 2D-laser scanners are installed above the two conveyor belts of the vessel. At each conveyor belt a scan level across the conveying direction of the belt is projected. A two-dimensional image of the bulk material will be developed and compared to a so called „zero-profile“ which was taken during the commissioning at the beginning. Out of the obtained data the software calculates the volume and mass flow rate of both conveyor belts parallel. By the use of high performance laser scanners with a scan ratio of up to 300 scans per second, the material is recorded reliably even at a high transportation speed (see fig. 8). Special algorithms for the adjustment and calibration ensure a high accuracy. The LASE measuring system allows a safe operation even under raw environmental conditions.

LaseCPY - Coil Profiling Yard

Published in Steel Logistics

Coil position and -dimension measurement in the yard: Our system is the eye of the control system and can provide the exact position information of the coils.

System features:

  • Exact positioning of coils and pits
  • Measurement of coil dimension
  • Damage-Free coil handling
  • Fully automatic loading and unloading in the yard
  • Robust measuring technology

Short description:
Depending on the coil dimensions and the general environment the measurement system LaseCPY - Coil Profiling Yard can consist of up to four LASE 2000D laser scanners, which are installed on the crane girder and a LASE Control Unit (LCU) for the evaluation of laser measuring data. On this unit the yard profile in its Y and Z-axis and an additional distance measurement for the crane position (X-axis) will be realized by a LASE 1000D laser scanner. Consequently a three-dimensional image of the yard is generated during the crane drive in order that positions of all coils in their X, Y and Z-direction are sent to the crane PLC and transmitted to the warehouse management system.
By means of this coil position data the warehouse management system generates information about the driving schedule for the automatic crane, the coil width and coil dimension.
