Introduction
The Web Train is a n-scale model train that is
controlled by a remote user. The Engine Location
System will determine the location and speed of
the engine
4
Future Applications

• At the end of the year a fully functional web
  train
• At the end of ten years a system for toxic
  manufacturing automation
• At the end of 50 years a underground mining
  operation on Mars

Current Sensing Methods
Method Pros Cons
8-bit with variable range Built in the microprocessor board, of trains Requires more software
10-bit Can determine of trains and of cars Expensive
2-bit 2-bit method can be designed cheap enough to have the A/D on every track segment, this reduces analog related problems Cannot determine of trains

Expansion to more Track Sections

• With only the inner loop, we cannot test direction

Must check 2 and 3

Equipment

• We will use the web train board
• If hardware system works well, we hope to make
  PCB
• New microcontroller board if necessary

Conclusion

• Successful because of
• A/D innovation
• Project can progress with current equipment
• Expandable

25
Conclusion

• Utility of this Project
• If user sets speed of each engine, why do we need
  a system to tell the user where the engine is?
• Internet has delaysthis is local information
• Can be used to implement collision avoidance
• Also needed train decoupling information
