The
embedded computer for the turnstile system
also serves
as the central controller and management
computer.
When visitors pass through the turnstile,
the embedded
computer receives signals from a sensor and
magnetic
card reader immediately, and then causes the
gate
to open and display a message on the
turnstile panel.
Moxa's V481 embedded computer is ideal for
this type
of application since it features a VGA
display and
2 LAN ports for network redundancy. In
addition, the
multiple serial ports connect the gateway's
sensor,
magnetic card reader, and panel. A real-time
control
and management system is a must for this type of
application. |
