How much material is on my stockpile? How much material is being conveyed exactly? How high are my wagons filled? Does my machine collide with people, other machines or the stockpile? Where is the material, what is the 3D-Profile for the automatic operation of my stacker or reclaimer?
These are just a few of customers’ questions. The LaseTVM systems are already in use worldwide and make everyday life easier for many customers.
The LaseTVM systems are high precision volumetric bulk material measurement systems for road trucks or mining trucks. The LaseTVM product family consists of the products LaseTVM-S and LaseTVM-M. With the LaseTVM-S (Static) version, the truck bed is placed centrally underneath the sensor(s). A measurement is made while the truck is at a standstill. With the LaseTVM-M (Motion), the truck drives through the measuring system without stopping and the measurement is made in transit. For both variants the laser scanners are installed above the driveway.
The LaseTVM-S variant uses a 3D laser scanner that generates a 3D profile of the loading area when the truck is at a standstill. With the LaseTVM-M variant, two 2D laser scanners are arranged 90° offset to each other – looking down. One 2D laser scanner measures the position of the measured object (truck with loading area) in the passage, the second 2D laser scanner generates a transverse profile (transverse to the direction of travel). By combining both sensor data, a 3D profile of the loading area is generated and the volume is calculated from this. In both measuring systems it is necessary to do a measurement in empty and filled condition. Both profiles are saved and then the calculation is performed, whereby the empty 3D profile is subtracted from the full 3D profile. The difference between the two volumes is the volume of the transported bulk material. A truck with one or also with two loading areas can be measured.
With the LaseTVM-S variant, a second 3D laser scanner is required for this case. Both product variants are available as a kit, whereby there is a basic kit with the sensors, cable set and the evaluation unit including power supply (in a control cabinet). In addition, there are various modules that can be optionally purchased. Module identification (number plate) With this module an OCR camera (OCR = Optical Character Recognition) is installed next to the driveway at the height of the number plates, from where the identity of the vehicle is recorded in the driveway or in the passageway. Module Identification (RFID). For this, an RFID tag (Radio Frequency Identification) is attached to the vehicle. Next to or in the measuring head above the lane is the RFID reader, which records the identity of the vehicle in the driveway.
