For over thirty years Smarte Carte has developed innovative products
and services that give people the freedom to enjoy their travel,
shopping or entertainment experience. Smarte Carte designs and
manufactures cart control systems that you see in Airports around the
This was my first job after graduating from Makato State
University. I was part of a small engineering group (about 10
people) that designed cart control systems. I was resposible for
the electrical and software engineering.
Two major projects spanned my three plus years at Smarte Carte. I
was involved in the development of the Microprocessor Based Counting
System (MCS). The Intel 8051 based system was used to gather and
store data from the Cart Control Unit. Data collected by the MCS
was then transmitted to a small hand held computer via RS-232c
interface. We prototyped this system in the Minneapolis Saint
Paul International Airport ... but the MCS System was never widly used.
The other project, included the development of the Microprocessor Based
Trolley Control Unit (TCU). The TCU would replace the existing
rental and return end of the control system so that Smarte Carte could
control other manufacturers carts. This product was marketed to
European Countries. The 8051 based product included 32K RAM, 32K
EPROM, expanded I/O and a 2x32 LCD Display with keypad. This
system was used to control the operation of cart rental and return
mechanisms, coin dispensing and accepting devices, bill acceptor,
credit card reader and a cart identification system. The
prototype was shown in a trade show in Frankfurt Germany and then the
project was caceled for marketing reasons.
Designed, prototyped and tested three microprocessor based embedded
systems for luggage cart rental systems in airports. The Intel
8051 based systems were used to manage data acquisition, control the
operation of cart rental/return mechanisms, coin dispensing/accepting
devices, bill acceptor, credit card reader and a cart identification
system. Application software was written using an 8051 Cross
Assembler and C Compiler.
