Industrial projects

 

The results of research and development activities at the DSP (Digital Signal Processing) laboratory can be successfully utilized by our industrial partners. Our research activities and results in the field of digital signal processing and embedded systems are applicable for industrial applications.

 

In the lab we continue the traditions of our department in instrumentation technology, as we develop instruments and measurement systems that measure and analyze some physical phenomena. We mainly develop mixed analog-digital measurement systems, where our extensive experience with analog electronics is combined with the powerful tools of modern digital signal processing. The signal processing algorithms are implemented on DSP-based (Digital Signal Processor) hardware, sometimes complemented by CPLDs or FPGAs.

 

In our projects we mainly use DSPs from Analog Devices Inc. For high-precision or computation-intensive applications we use members of the 32-bit, floating point SHARC family. For more lightweight or control oriented applications we use the members of the BlackFin embedded processor family. These DSPs already have the capabilities that are expected from a standard microcontroller besides the signal processing capabilities, therefore they are able to perform all the control and communication tasks along with the core signal processing algorithms. Accordingly, our systems can be used as stand-alone devices or together with a host PC. System configuration, calibration, online or offline monitoring are also performed via a PC.

 

A few successful industrial projects: 

 

DRD - Dynamic railway diagnostic system

Dynamic scale and wheel diagnostics systems for trains moving up to 150 km/h. The deformation of the rail is measured by strain gage sensors. Diagnostics including swinging motion and faulty wheel detection.

Flow - Magnetic flow-meter of conductive fluids

Flow-rate measurement of conductive fluids based on the
electromagnetic induction. The flow-meter has two different versions for full and also for partially full pipes. The latter can be used to measure the flow-rate of natural water or wastewater.

Gas-Flow - Ultrasonic gas flow-meter

Development of an ultrasonic instrument to measure the
flow-rate of gases. The project is sponsored by the Economic Competitiveness Operational Program (ECOP).
