Introduction: Edison Head Impact System

About: TAMS'19 -- Maker Enthusiast -- Research Nerd -- Explore. Make. Share.

The goal of this project was to create a device that monitors the intensity of head impacts and detects impacts that have a high likelihood of producing a concussion. In youth football, this medical device can be an additional “set of eyes” overseeing the safety of the players and notifying coaches when something’s wrong.

****************************REMEMBER TO BACKUP ORIGINAL EDISON FREQUENTLY****************************

Step 1: Setup Intel Edison

Go to this Website: https://software.intel.com/en-us/get-started-ediso...

FOLLOW the instructions THOROUGHLY and complete the Installation Process/Firmware Update.

Setup the Wifi: configure_edison --wifi

Setup the Name: configure_edison --name

Setup the Password: configure_edison --password

Setup the Date:

rm /etc/localtime

ln -s /usr/share/zoneinfo/America/Chicago /etc/localtime

ls -l /etc/localtime

Step 2: Setup RTIMULib

Download RTIMULib Zip File onto Laptop: https://github.com/RTIMULib

Use SFTP to transfer the unzipped RTIMULib File into the Intel Edison's root directory.

Enter these commands to install RTIMULib's Linux system:

Create /etc/ld.so.conf and add the line: "/usr/local/lib"

Under the RTIMULib Library enter these commands:

mkdir build

cd build

cmake ..

make -j4

make install

ldconfig

Under the /Linux/RTIMULibCal Library enter these commands:

make -j4

make install

Under the /Linux/python Library enter these commands:

python setup.py build

python setup.py install

Step 3: Java and Tomcat Setup

Once completing the RTIMULib Setup, download the most recent Python programs and "Players Info" Folder from the most recent Edison backup through an SFTP Session.

***REMEMBER TO BACKUP ORIGINAL EDISON FREQUENTLY

You have to add Java:

mkdir java

cd java

Move jdk.blah.blah.blah.tar.gz from backup to edison via SFTP Session

tar -zxvf TARNAME

Now, for the TOMCAT, here's how to download and setup the web server (starting from the root directory):

mkdir tomcat

cd tomcat

Move apache-tomcat-blah-blah.#.#.#.tar.gz (**Not exact file format) from backup to edison via SFTP Session

tar -zxvf TARNAME

cd apache-tomcat-9.0.0.M1/conf

vim tomcat-users.xml

*Delete the Comment around the Roles and add a line under the list with "roles="manager-gui"/>"

vimcontext.xml

*Change "" line to "privileged="true">"

cd ../bin

vim startup.sh

*Add "export JAVA_HOME=/home/root/java/"

vim shutdown.sh

*Add "export JAVA_HOME=/home/root/java/"

Now Check if the Web server can be started through "./startup.sh" and shutdown through "./shutdown.sh" under the bin folder.

**Ignore "Catalina Server may not be running" error, and try startup and shutdown a few more times...


Step 4: EHIS to Executable and Auto Web Server

Creating eHIS Executable Program:

Add "#!/usr/bin/python2.7" to the top of eHISprogram.py

Then Enter Command: chmod u+x eHISprogram.py

Automating Web Server:

mkdir /etc/init.d

cd init.d

MOVE edison.sh from Backup to init.d dir via SFTP

EDIT edison.sh by Changing Locations of startup.sh and shutdown.sh

chmod 755 edison.sh

update-rc.d edison.sh defaults

Step 5: Setting Up Ubidots (Cloud) Device

Enter Commands from root Directory:

cd RTIMULib-master/Linux/python/tests/OfficialSFprograms/

python eHISnewCloudSource.py

Configure Device Variables:

Sign into Account at https://ubidots.com/

Click on Sources Tab

Click on the Device

Click on the impact_Graph Variable

Copy the Variable ID

*cd RTIMULib-master/Linux/python/tests/OfficialSFprograms/

*vimeHIS.py

*PASTE the impact_Graph Variable ID under the quotations of impact_Graph = api.get_variable("")

**REPEAT for other 3 Variables

Step 6: Setting and Testing TomCat Webserver

***You need the Original Edison's Most Recent Backup for this process

Steps to Install and Run Local Edison Webserver:

Through an SFTP Session, copy the Edisonwar folder and the Edisonwar.war file from backup into the /home/root/tomcat/apache-tomcat-9.0.0.M1/webapps directory.

Startup the Webserver

Go to the Host Manager on the browser using "rikseddy#.local:8080" and check if the EdisonWar App is listed

Access the EdisonWar App and Check Out the Impact Table...

Finally, test the Edison Head Impact System program:

./eHISprogram

***If there are "file not existing" or "directory not existing" errors, fix them by copying those files/directories from the backup into their respective directories.

Check the Local Host's Web Server:

Access the local host using "localhost:8080" on the Mac and access Player2 under the Chartwar

Check if the Impact data table has updated with the most recent data from testing the python program.

    Thank You! It took several weeks to think of and build the design, but it was totally worth the time.
