AAEON Embedded Controllers Help Reduce Carbon Footprint
for Public Transport Buses
The well-connected bus network brought
convenience to everyday commuters, but just how effective are we in reducing
the carbon footprint in our public transport through reductions in fuel
consumption and carbon emissions?
As a move towards a cleaner planet, governments
generally encourage people to take public transport, such as buses, trains, and
rapid transit so as to reduce carbon emission. However, carbon emission volume
is not only about the number of vehicles on the road, it has also to do with how
the driver drives to optimize fuel utilization. In order to minimize the carbon
footprint brought about by today’s public transport, vehicle transport
companies are beginning to install systems used for monitoring and managing carbon
emissions, and are looking into ways to optimize fuel consumption for greater energy
savings.
The system, usually a rugged embedded
controller, has to be fanless, and capable of connecting with external I/O
modules and sensors in order to detect vehicle carbon emissions and fuel
consumption via built-in CAN bus protocol and RS-485 serial ports.
The embedded controller collects real-time data
of carbon emissions and fuel consumption, and sends these data via wireless LAN
and GPRS (via mini PCIe interface) back to a Control Center for data monitoring
and analysis. Each vehicle in the fleet is
fitted with an embedded controller able to collect real-time information of the
driver and route taken, and status of the fuel system and engine of the vehicle
through the CAN bus. The embedded
controller also monitors each fueling event, when the vehicle is refueled and
fuel levels. With statistical data over a period of time, steps can be taken to
reduce carbon footprint for each vehicle.
Due to the nature and space constraints of
public transport vehicles, embedded controllers need to be rugged and compact
in design to withstand shock and vibration incurred on the roads. Although passively cooled, embedded
controllers need to have excellent thermal cooling mechanisms for them to
operate under large temperature variations, throughout a day and through the
different seasons of the year. A well
designed embedded controller is required to be low powered, yet having a high
performance per watt ratio (e.g. Intel Atom processors) to guarantee stability
and reduce maintenance costs during its lifetime. Compatibility and stability connecting with
external peripherals and sensors is also a serious consideration for system
integrators.
Today, embedded controllers are used more and
more outside of the control rooms and factories, this time to monitor and
control vehicles in energy saving, and to reduce greenhouse emissions for a
cleaner world.
