Railroad Signal Control System
_____________________________________________________________________________
Starting in the year 2000, traveling by train in Taiwan was made
more efficient and safer with the incorporation of MOXA C320 Turbo.
Several hundred of these intelligent multiport boards are now
being used as part of an integrated island-wide railway control
system.
The basic structure of this railway signal control system is
to deploy DGPs (Data Gathering Processars) every 10 to 15 km at
key intersections around the island. The information collected
by the DGPs is transmitted by modem to IPCs (Industrial PCs) placed
at one of 20 regional monitoring centers. With this setup, one
host can collect and analyze data transmitted from as many as
32 DGPs. The information is then sent via the Internet to a central
control and monitoring station.
Many benefits can be realized by incorporating MOXA C320 Turbo
in this type of railway monitoring and control system. For one,
emergency response time can be shortened. Staff in the central
control center can use information of railway activity collected
from the remote monitoring stations, allowing emergencies to be
responded to in good time. And train delays can be minimized by
applying intelligent diversion strategies. MOXA C320 Turbo can
also help to reduce maintenance costs. Staff in the central control
center can easily determine which instrument at a specific intersection
is broken, and then respond quickly to have it repaired.
Overall Benefit:
Shortened emergency response time; reduced maintenance costs.
