When we designed out low power signage, we started at the beginning and implemented a suite of supporting services:
- Battery charging electronics, optimised for solar supply
- Remote monitoring capabilities
- A local communication architecture allowing for the monitoring of our sub-systems, and potentially third party systems and sub-systems
- Open interfaces to allow operation with third party components
Therefore, our equipment should not be thought of as “just displays”. They are programmable computers which are permanently linked to our central servers over VPN.
They have been used to:
- Control real time signage
- Control audio outputs
- Manage Wi-Fi connectivity
- Measure traffic speeds (vehicles)
- Measure train speeds, and determine if they are speeding up or slowing down
- Control warning signs at level crossings
- Detect Objects
- Detect movement
- Provide Power
We call this service, CERBERUS, and as well as providing a verifiable power source (including real time details about the power reservoir), it can provide complete information about remote systems in the field in real time. Whether this is verifying availability, verifying performance, or feeding back data, or indeed receiving data and as a result triggering events (including providing confirmation back via feedback loop), CERBERUS can provide full remote system monitoring and management.
Naturally we use this to monitor our own hardware, but the supply of verifiable power and the real time monitoring of sub-systems provides a flexible platform to do just about anything, anywhere. Compatible with 3G/4G and satellite links, real time communications is handled seamlessly.
SOLAR PANEL PERFORMANCE
BATTERY LEVELS AND SUB-SYSTEM PERFORMANCE
HERMES LITE is the computer at the heart of all of our low powered/solar powered equipment. It is a fully programmable computer which runs diagnostic and monitoring software on a Linux OS.
HERMES Lite is therefore not just a sign controller – it is a low power computer, permanently connected to our managed infrastructure. Any systems we supply can therefore become part of an ecosystem – part of the IoT.
