Introduction
With
the
social
development
and
progress,
traffic
flow
becomes
increasingly
important. On the one hand, too many crossroads, more and more vehicles, which are
causing
serious
traffic
congestion.
On
the
other
hand,
in
the
limited
time
it
is
necessary to maintain the vehicle and pedestrian fast and safe. Therefore, one kind of
traffic
light
control
system
design,
can
be
used
to
display
time
countdown,
with
computer
controlled
real-time
data.
In
addition,
the
configuration
technology
for
real- time images that reflect the traffic lights, understand the historical crossroads of
work
to
get
traffic

visualization.
The
system
consists
of
host
computer
and
a
low computer. MCGS configuration is installed in the host computer is lower by the
PLC control system.

But
there
are
some
urgent matters, for example. There are a number of ambulances to transport patients to
the
hospital
or
to
deal
with
a
number
of
fire
engines
and
fire.
Fire
engines
and
ambulances
rushed
to
take
precedence
over
other
traffic
scene.
According
to
urban
traffic control system, under normal circumstances, two control methods and urgency
traffic control factors into account. This process can show 14 segment encoder. U.S.
traffic lights instant record of the monitoring process.
Emergency
control
signals
to
control
traffic

switch.
If
there
is
no
emergency lights all work, but when an emergency open. In this case, the car is urgent
priority pass. Once the emergency vehicle passes, emergency switch off immediately.
The
green
light
in
the
same
direction
of
the
vehicle
quickly
flashes
three
times,
followed by the normal operation. If you were from the north-south and east-west two
emergency vehicles, traffic control systems can respond quickly came early, and then
another.

Monitoring System

Computer
system
has
two
main
functions:
an
output
signal
acquisition
and
display real-time status of the programmable logic controller (PLC) to control traffic
lights, traffic lights. Another notification robot status and history of the state real-time
curve by examining the history and alarm window.
This monitoring system design and configuration software MCGS configuration
is easy. The serial communication is implemented as follows.

Data inspection methods: double ended
Serial Communications Number: COM0 ended
The minimum sampling period: 200 ms
Programmable Logic Controller (PLC) The parameters are defined as follows:

The minimum sampling period of the basic properties: 200 ms
Three read / write channel: X0, X1, X2
Six read-only access (read U.S. traffic lights): Q0-Q5
All
channels
must
be
connected
to
a
variable

parameters

After

relationship,

is
able

Conclusion

Experimental
results
show
that
the
system
is
usually
configured
with
enough
good photos. This system simplifies the programmable logic controller (PLC) and the

development time is greatly reduced. In particular, more suitable for complex control
systems.
We
can
control
the

by
the
PLC
and
MCGS
configuration,
replace the original relay control, improve the system's lifetime. At the same time, this
method
can
be
applied
to
control
the
motor
and
fluid
levels.
Remote
control
and
configuration combined with the simulation, can be applied to similar control zone.
