Mid-Presentation Project “Koala”
Winter 2014High Speed Digital Systems LabPresented by: Stephen TaraginSupervisor: Boaz Mizrachi
Single semester project
Motivation
Relaying information regarding the physical condition of a given road.
Part of the “Wisdom Stone” project
Taking it to the “next level” – Relaying the information.
“The Wisdom Stone”Small electronic devices placed under
the roads in various places.Gathers information about the physical
state of the road by means of sampling the vertical acceleration of the road while vehicles drive over.
Each stone processes the information and relays it to the hub, who then relays it to the command center who determine if something is wrong with the road.
The Overall System
Project Goal Defining and building an
electronic hub which will enable relaying the information gathered by the wisdom stones under the ground to a control center.
Creating the ability to remotely maintenance the hub.

Block Diagram of the Hub
Maintenance – "Watchdog" The maintenance is basically a software written in
the cpu of a wisdom stone placed in the hub which determines the status of the phone, battery and solar panel charger.
We would like to assure the hub and it’s components are working and their status without having to physically be there.
The maintenance should be able to restart the cell phone in an event of software failure, other problems.
The maintenance should also be able to turn the phone on/off remotely.
The maintenance will receive a signal indicating the current battery level and other signals indicating the status of the charger.
