Electronic
Toll Collection System
Project
Introduction:
In recent years, highway toll systems have become more complex.
Toll collection systems need to be able to collect monies
from a range of sources i.e. cash and credit cards. But these
require toll booths and therefore slow the flow of traffic.
To alleviate these issues and keep the traffic moving a recent
addition to the collection system is to build a highway with
no toll booths. Electronic Toll Collection (ETC) systems use
gantries over the highway, with monitoring equipment, in the
form of transponders, to gather information from cars and
lorries passing beneath them.
System
Requirements:
Based on the requirements of the Nanjing Airport Expressway
in China i.e. assorted payment options, continuous operation
and outside installation, the toll system needs an industrial
computer with a number of serial communication cards to connect
and control the systems. The automation system not only needs
to send the related data to the control center but it must
also has to control many objects such as the barriers and
display boards, as well as being able to recognize vehicle
license plates, control trigger settings and capture a photo
of the vehicles.

Description:
Advantech’s
UNO-3072A solution provides a multi-function toll system with
robust and reliable features. The monitor, with a microprocessor,
voice prompting device, and an automatic card reader connects
to the UNO-3072A platform PCI-1620BU communication card which
provides reliable, high-speed serial communication. With the
addition of Advantech’s network interface and video capture
cards (to help our client to design and implement the toll
system), the system can smoothly control the devices in each
lane and automatically detect the device’s operational status.
Conclusion:
In order to meet the fast, accurate, reliable and efficient
requirements, the highway toll system needs to integrate the
computer, internet, and application software to prevent the
traffic congestion and reduce the errors caused by manual
processes. Advantech’s industrial-grade computer, serial communication
cards, and digital I/O cards offer a total solution with the
best performance and stability to complete highway toll system
as well as significantly improve the flow of the traffic and
build a stable payment system.
