Wireless Loop Reader Information System
Loop Reader - What is it?.
|
|
Reads loops without taking the Model 170 Traffic Controller offline |
|
|
Converts loop data into Log170 format |
|
|
Uses hardwire Ethernet, IEEE-802.11, or GPRS for communication (i.e., IP-Based) |
|
|
Operates as a server to handle client requests |
|
|
Has built-in voice guided instructions for system installation and diagnostic |
|
|
Stores data in a database |
|
|
Allows users to access data through a web browser |

Motivation
This project is developed to support the VideoSync program and can be utilized independently for other purposes. Traditionally, data are collected through the Model 170 Traffic Controllers that are not running Log170 software. Therefore, the collected data are not in real-time and Log170 format. VideoSync requires Log170 data to operate. That means the Model 170 Traffic Controller needs to be taken offline each time for collecting Log170 data and firmware installation. With the loop reader, it provides Log170 data and enables users to access data through a wireless Ethernet anywhere. Plus, no controller has to be taken offline.
