Unmanned Site Management – Roadside
Cabinet Monitoring with Active Ethernet I/O
Project Introduction Many industries rely on roadside cabinets to provide service to multiple households at a specific area. Different types of equipment
may be installed, such as traffic devices, vehicle sensors, or telecom servers. Originally, roadside cabinets were primarily used to
serve rural and remote areas, but they are now common in urban areas as well. They can be found next to a highway or next to a sidewalk, almost anywhere a person may look.
System Requirements A client wanted to establish an intelligent transportation system,
which meant that the traffic control equipment in various
roadside cabinets had to be monitored in real-time. In addition,
the cabinet itself needed to be monitored to minimize downtime.
The most effective method of communication was over Ethernet
IP networks. However, monitoring hundreds of cabinets along
the highway would require an overwhelming amount of CPU and
network resources, as well as programming effort. A solution
was required that satisfied the following requirements:
Event-driven alarm messages
At least two digital input channels
Output channel to reset power
Ethernet interface
Easy mass deployment and firmware upgrade
System Description
The widespread popularity of Ethernet made it an ideal medium
for roadside cabinet monitoring. Fiber cable was already
installed along the highway to transmit traffic signals and
video feeds to a control center. An ioLogik E2210 was installed
in each cabinet to monitor door and power status. Since the
ioLogik provides digital output channels, it was also used to
reset power remotely if there was an equipment malfunction.
Furthermore, mass deployment was easily achieved since the
ioLogik supported TFTP for configuration over Ethernet.

Conclusion
ioLogik E2210
Active Ethernet I/O server with 12
digital inputs, 8 digital outputs
The ioLogik E2000 series is designed for Ethernet-based remote monitoring and control systems. Straightforward and accessible design means your monitoring system can
be deployed easily and quickly. With the ioLogik E2000, a new approach to remote monitoring can be used for many roadside cabinet applications, such as transportation, power meters, gas meters, water meters, and cable TV.
