Part II: Roadway Traffic Control System

ITS
(Intelligent Transportation Systems) is playing a major
role in modern transportation construction, with ITS technology
applied to roadway traffic control systems. In general,
ITS involves integrating communication, control, and electronics
technologies, and is used to monitor and manage traffic
flow, reduce congestion, provide alternative routes to travelers,
and enhance productivity to save lives, time, and money.
System
Description
Roadway
systems are made up of many subsystems, including Traffic
Signal Control Systems, Traffic Information Display Systems,
Real-time Traffic Video Monitors and Analysis Systems, and
Power Substation Systems.
ATMS
(Advanced Traffic Management Systems) and ATIS (Advanced
Traffic Information Systems) are two of the most important
aspects of ITS, and as such much of the cost for ITS implementations
goes into ATMS and ATIS. By using intelligent embedded traffic
controllers, traffic signals, vehicle detectors, LED display
boards, and traffic surveillance cameras, a road group with
several adjacent intersections can work together as one,
coordinated system.
- Vehicle
detectors collect traffic flow information, including
volume, speed, occupancy, and then send the information
to an intelligent embedded computer over a wireless transmission
system.
- The
embedded computer, which acts as a traffic controller,
calculates and analyzes the data to determine the state
of the traffic flow, and then makes control decisions—such
as when to change a particular traffic signal from red
to green—to avoid serious traffic jams.
- The
controller sends the estimated travel time information
and suggested alternative routes to the CMS (Changeable
Message System) display board to alert drivers of the
current traffic conditions.
A major
concern is system reliability. Due to the importance of
traffic control, the roadway system cannot be allowed to
fail due to power failures or disconnected transmission
lines. Furthermore, since the traffic situation changes
from day to day, and car accidents occur unpredictably,
an additional traffic monitor/surveillance mechanism should
be set up for prevention and emergency response.
Requirements
A roadway system designed with a solid and reliable networking
infrastructure and perfect traffic control/display strategy
can help to ensure higher performance. The following items
are what's needed to create the roadway system:
- Real-time
surveillance and capture—Video surveillance
must be available to provide real-time pictures of actual
traffic conditions.
- Wireless
network—Traffic controllers at each intersection
in the road group can synchronize the information by using
wireless to transmit at least some portion of the signal
over either a wireless or wired network, helping save
on the cost of cabling.
- Embedded
computing—The embedded computer calculates
control signals in real-time to make the right traffic
management decisions.
- Redundant power and network—Redundancy
plays an important role in transportation systems, since
it can help keep the system running non-stop.
- Extended
temperature—In general, devices used for
transportation automation must be able to operate in and
withstand extreme temperature conditions, such as from
-40 to 75°C.

| UC-7110—Energy
Monitoring and Management System |
|
Moxa's UC-7110 embedded computer is a compact and programmable
serial to Ethernet gateway. In this application,
UC-7110 is used to manage
serial
data received
over the Internet from power meters.
Background:
As the world's population continues to increase and new
factories spring up all over the place, the problem
of providing
enough electric power has become a big concern. The "solar
power solution," which has received much publicity
and backing from environmental enthusiasts, is becoming
more mainstream.
Solar
power systems use roof solar panels to absorb the Sun's
energy. The purpose
of the panels is to convert solar engery into electric
energy, which is sent to a control box via RS-485 serial
wires.
Power companies that offer renewable energy systems are
making increasing use of the Internet to manage and
monitor
their systems. Due to the nature of this application, a
programmable serial to Ethernet communication gateway
is
needed to convert RS-485 serial data into a format suitable
for transmission over Ethernet.
Solution:
Moxa UC-7110 offers an economical and resourceful solution
to reroute serial data to an existing Ethernet network.
The solution provider can embed their own monitoring and
protocol conversion software into one of Moxa's UC-7110
embedded computers to handle all power generation and consumption
data. As a front-end controller, UC-7110 is compact, and
has customizable programming options to convert all serial
data received from multiple power meters to Ethernet packet
format. By using UC-7110 to replace the PC, not only is
cost reduced, but system managers obtain greater flexibility
due to UC-7110's small size.

Benefits:
- UC-7110
is a compact sized Linux computer
-
Easy to port existing applications to the Linux platform
-
Use the Linux environment to shorten the programming learning
curve
-
UC-7110 is a front-end, reliable, fanless, cable-less

| UC-7420—Monitoring
Unmanned Weather Stations |
|
Introduction
Unmanned weather stations play an essential role in the
effort to analyze and predict the world's ever-changing
weather patterns. The unmanned stations collect and store
large amounts of weather data and then download the data
at regular intervals to a back-end host for analysis and
long-term storage. The computing device housed in the weather
station must be robust enough to work continuously for long
periods of time while exposed to a wide range of temperatures.
It should also be able to collect readings from diverse
sensors that use different data transmission protocols,
and have the capability to store large amounts of data.

Protocol
Conversion and Front-end Data Processing
The data collected by a typical unmanned weather station
includes temperature, rainfall and snow amounts, air pressure,
humidity, and ultraviolet intensity. One of the tasks that
the UC-7420
unit must handle is protocol conversion, since there is
no guarantee that the devices collecting the weather data
all use the same protocol. In addition, the UC-7420 can
be used to do preliminary data processing before downloading
data to the central computer. Moxa's UC-7420 is ideally
suited for these tasks, since the user can easily embed
a C program that is custom written for the devices used
at the station. If future changes involve adding or removing
devices, the programmer simply needs to modify the C code,
recompile it, and then download the executable program over
the network to the UC unit.
Connecting
to the Network and the Internet
In addition to being programmable, UC also offers users
with an array of connection options. To begin with, data
entering the serial ports from attached sensors can be processed
and then forwarded through one or both of the dual Ethernet
ports to the LAN. One of the serial ports can also be connected
to a V.90 or GPRS modem for PPP connections, and a PCMCIA
port is available for installing a wireless LAN card for
802.11b/g networks. By including multiple connection options
in UC's design, user's gain the flexibility needed to connect
from virtually anywhere. Combinations of connection types
can also be used to provide redundancy. For example, if
unavoidable network problems cause an interruption in service,
the user can connect by modem.
CompactFlash
Storage Space
One of the dilemmas faced when creating a "small"
computer is how to provide users with adequate storage
space. For unmanned applications, it is best if the storage
device
does not contain moving parts. Although for day-to-day
use it may seem that hard drives last forever, we cannot
make
this assumption for continuous use at a remote location.
Moxa's embedded Linux computer gets around this problem
by providing a CompactFlash slot. If needed, Flash memory
cards with
storage
capacity
of up to several Gigabytes can be used to store data until
it's convenient to transfer the data to a central computer.

Benefits
of Using Moxa's Embedded Computer
- No
fan, no hard drive design for longer MTBF
-
Compact Flash slot for adding Gigabytes of storage space
-
Dual-LAN ports for setting up super-redundant systems
-
Programmability gives system integrators infinite possibilities

| NPort
IA—Fuel Duct Monitoring Case Study |
|
One
of the most important tasks for petrochemical applications
is monitoring the status of oil pipes. In the past, information
was gathered manually, but with the NPort
IA series, engineers can monitor oil density, oil
pressure, and oil temperature over an Ethernet connection.
Furthermore, since the distance between measurement points
could be 1 km, 1.5 km, or even more than 10 km, fiber
Ethernet is a convenient choice for this type of application.
The NPort IA series has passed Class I/Div II explosion-proof
certification, which provides a further guarantee of
the products' safety.

Technologies Connects BabyLove Art with Wireless Application |
| Moxa
Technologies was happy to provide several wireless
serial device servers to the BabyLove project, which
will be
displayed
at the National Taiwan Museum of Fine Arts. The BabyLove
project, which took four months to complete, was led
by
the well-known artist Shu Lea Cheang. Mr Cheang and eight
teams located around the world used digital technology
to
create this avant-garde audio-visual art exhibit.
The
BabyLove exhibit consists of baby dolls seated inside large-sized
spinning coffee cups that double as bumper cars. A combination
of red, blue, green, yellow, and orange colors is used to
create a striking and attractive display. Each of the dolls
has a wireless device server hidden in the doll's
interior, and two speakers are attached to the doll's
diapers to transmit sound. Spectators who sit in the cups
can upload their favorite music to the doll's music
system over a wireless network. When one cup bumps into
another, the two participants will be able to hear each
others' music emanating from the speakers in their
own cup. The purpose of creating such a unique combination
of dolls, bumper cars, and digital technology is to emphasize
how modern technology can be used to enhance interpersonal
communications.
The
BabyLove project will be exhibited on December 8th
at the Palais
de Tokyo exhibition hall in Paris, France, and in May at
the National Taiwan Museum of Fine Arts.
The
Moxa product used for this project is NPort 2150, a wireless
serial device server that is used to connect serial devices
to a wireless network. More information about this product
is available on the Moxa Group's website at http://www.moxa.com/product/NPort_W22502150.htm
