Requirements

  • Replacing the old displays (big 7 segment wall displays with LEDs) with modern jumbo screens
  • Replacing the outdated evaluation electronics with industry PCs controlled by LabVIEW
  • Employment of modular state-of-the-art measurement technology
  • Integration of additional displays into the control units
  • Highest ruggedness and reliability
  • Simpliest usage
Wheelchair Simulator Controlled by LabVIEW and LabVIEW Real-Time/RT

Solution

Software development and programming in LabVIEW (National Instruments). Employment of CompactDAQ systems with NI cDAQ-9174 (Chassis), NI 9411 (Encoder), NI 9421 (8xDIN) and NI 9472 (8xDOUT). Installation of additional LCD displays EA DYN4016 (Electronic Assembly) into the control panels, controlled via RS232/RS485.
