Building Automation
Location: China
Project Introduction:
A
train station in China was looking to develop an equipment monitoring
& controlling system at their substation in the main building of
their station. Concerned with future expansion of the station, they were
also looking for a solution that could be easily upgraded in the
future, and even expanded into other substations. Thus, Advantech
stepped in to help them realize a complete and easily expandable
Building Automation system.
System Requirements:
The
train station wanted an expandable central monitoring & controlling
system which could monitor over six different subsystems, including an
air conditioning system, water supply and drainage system, lighting
& emergency lighting systems, escalators, and a variety of other
equipment. They also wanted a redundant network backbone to guarantee
reliability and hoped that the solution would also be able to monitor
power usage to save energy costs as well.
Project Implementation:

Browser-based HMI/SCADA Software |
BAS-3512/3520 |
12-ch/20-ch Web-enabled DDC Controller |
BAS-3024 |
4-ch UI, 4-ch AO, 4-ch DO Expansion Module |
System Description:
The
station's mechanical and electrical equipment monitoring &
controlling system is built on a distributed structure composed of a
central monitoring & controlling system, a field controlling DDC,
input & output equipment and the corresponding communication
network. The network architecture of the equipment monitoring and
controlling system uses a redundant and fiber-optic solution, which is a
main feature of the EKI series. What's more, combined with
energy-saving DDC equipment and WebAccess software, the system not only monitors and controls all of the
respective equipment and systems, but also helps the station to save
power, energy and money. The substation's system consists of: air
conditioning system, water supply and drainage system, illumination
system, emergency illumination system, low-voltage transformation and
distribution system, and escalator.
Conclusion:
With the functions of DDC field controlling and WebAccess monitoring & controlling, Advantech's BA solution not only meets
the needs of safety monitoring & equipment controlling, but also
saves energy. For the air-conditioning system, WebAccess saves energy through scheduler management; which is how it saves energy
similarly in the illumination system. Furthermore, the X-ring redundant
network of EKI series ensures 24-hour system operation without
breakdown.
