Introduction
Project Introduction

Traffic congestion from tollgate bottlenecks on busy highways not only prolongs commuting times, but also increases CO2 emissions. As a result, transportation authorities around the world are implementing ETC (electronic toll collection) systems to help keep traffic moving on busy highways. These unmanned tollgates are equipped with laser detectors that identify vehicles by size and generate a pulse output to trigger different IP cameras in the gate area to take snapshots for violation enforcement. By keeping highway traffic flowing free, ETC systems can shorten commutes and reduce greenhouse gas emissions.


System Requirements

-Counter function
-Local control capability for local output
-AI channel for water leaking detector, electricity status, and air-con status
-RS485 Interface for temperature/humidity sensor
-Ethernet Communication


Moxa Solution

A toll road in Taiwan was able to alleviate gate area congestion by using the ioLogik E2212 and E2242 micro RTU controllers to construct an Ethernet-based ETC monitoring system. In each ETC gate area, SICK laser detectors are used to identify the size of approaching vehicles and generate pulse outputs, which are collected by the ioLogik E2212 micro RTU controller with a high-speed I/O scanning rate and latency under 50 milliseconds. The ioLogik E2212 then sends CGI commands to trigger IP cameras in the gate area to take snapshots or surveillance video. In addition, installing the ioLogik E2242 in unmanned remote sites along the highway provided an AI channel to detect water leaks and monitor electrical conditions, and an RS-485 serial port for temperature/sensor monitoring. Furthermore, Moxa’s programming-free Click&Go™ logic offers a straightforward “if-then-else” control logic that gives users the flexibility to define different traps and customize front-end control.
