Transportation Embedded System

What is an example of an embedded system in transportation?

Example: Fare collector system on a bus. System has to be able to accept coins, bills, scan monthly or yearly passes as well as validate/cancel purchased tickets

 

Constraints:

  • mean time between failure: 2 years 
  • work efficiently using bus’ existing 24 VDC power system
  • communicate every shift with the central computer system
  • sealed system so change, water drops, snow, dust cannot enter the system
  • maintained by the bus driver
  • conduction cooled-no fans

Can you imagine a PC doing these tasks?
