Mobile Measuring Tower for Vehicle Component Test Beds
Lueneburg, Germany, October 5, 2010 - Werum Software & Systems AG is supplying the German car manufacturer Daimler with a custom-made data acquisition solution for a number of vehicle component test beds at Daimler's site in Hamburg, Germany. Werum's system will operate from a mobile measuring tower. It is freely configurable by the user and capable of recording data for up to 24 measuring channels. It visualizes and monitors the data in real time and ensures that it remains within defined limit values.
Real-Time Measuring Signal Acquisition
As part of the vehicle development process, Daimler tests vehicle components mechanically. With exacting customer specifications, Werum conceived and designed an efficient and freely configurable software solution for data acquisition and control, based on the CompactRIO platform from National Instruments. The mobile measuring tower will be built by another supplier.
The measuring tower's powerful hardware enables it to receive 24 sensor signals in parallel and in real time. It saves these signals and converts them into interpretable data. Werum programmed the hardware components with LabVIEW-RT and LabVIEW-FPGA according to the customer's requirements, and also designed the graphical user interface for visual representation of the data on display devices.
Configurable System enables Flexibility
The system is remarkable for its high scalability: The user is able to set the application to a specific scenario depending on the measuring task, and can either revert to predefined configuration tables or use input dialogs to adjust the measuring tower to each specific test, as required. While the system is receiving signal data, it automatically determines minimum and maximum values. These are then checked against predefined limit values. Any violation of these limits will trigger a defined action, and the test bed is usually switched off to prevent damage. On the monitor, the user can view a graphical representation of current values in an x-t diagram, and the values are also available on numeric displays in separate, movable windows. Depending on the measuring task, the system can display up to 24 different parameters.
If a signal is outside the measuring range, the background of the associated parameter changes to red in the display.
