  1. Team of Timisoara LEEFT3: Lift (Elevator) Environment Forged Tenderly by the Team of Timisoara Hard & Soft Contest, Suceava 2005

  2. Contents • Project 1 - Software • Project 2 - Hardware • Project 3 - Hybrid • Extensions: • Working scaled model • Multiple elevator shafts Presentation summary

  3. Project 1 – Hardware • Elevator model contains 4 floors, single elevator shaft. • Elevator controller implemented using “pure” hardware: • PIC microcontroller runs specialized algorithm; • Hardware bundle: buttons, sensors, LEDs, RS232; • GUI on the PC for signal display .

  4. Project 1 – Hardware (cont’d)

  5. Project 2 – Software • Same elevator model as Project 1. • Elevator controller implemented using GUI driven simulation: • Similar algorithm to Project 1; • Developed in Visual C ++; • Neat visual interface.

  6. Project 2 – Software (cont’d)

  7. Project 3 – Hybrid • Differences from previous projects: • Multiple elevator shafts; • Keypad on the floors, not inside the lift cage; • Elevator controller implemented a combination of hardware and software: • Algorithm; • Dispatcher;

  8. Project 3 – Hybrid (cont’d) • Multiple Elevator Shafts: • Lifts working in tandem; • Efficiency; • Keyboard outside the lift cage: • State-of-the-art in elevator field; • Planning algorithm;

  9. Project 3 – Hybrid (cont’d)

  10. Working Scaled Model • A working scaled model was built: • DC motor – H-Bridge; • Double Mechanical Reduction; • Photo sensors on every floor; • Counterweight;

  11. Working Scaled Model (cont’d)

  12. Prospects • Some further developments: • A.I. Algorithms; • Database support; • Safety issues
