Introduction
MOXA's UC-7420 embedded computer
is a miniature front-end computer for device networking
applications that is ideal for vehicle monitoring systems.
The UC-7420's small size, multiple connection options,
no-fan/no-hard-drive design, and programmable Linux
operating system combine to give system designers a
great tool for building a robust system that can be
used both indoors and outdoors.
Proximal vehicle monitoring involves
detecting or observing vehicles that enter a fixed "live
zone." Important vehicular behavior can be obtained
by establishing multiple live regions at different locations.
There are two types of proximal monitoring: Smart Vehicle
Monitoring and Dumb Vehicle Monitoring.
Smart Vehicle Monitoring
In this case, a computer with a wireless Ethernet card installed is located in the vehicle. The live zone is the connection region of a wireless LAN. When the vehicle enters the wireless LAN region, the vehicle connects to the network to download information to a central location, or receive updates from headquarters.
Dumb Vehicle Monitoring
In this case, the vehicle operates independent of the monitoring device. Monitoring is usually done by a surveillance camera. Vehicles are monitored as they enter and leave the zone, and with the right kind of software, speeds can be recorded, with pictures stored for later reference.
Benefits
- No fan, no hard drive design for longer MTBF
- CompactFlash slot
for adding gigabytes of storage space
- Multiple connection options for greater networking versatility
- Programmability gives system integrators infinite possibilities
