Recent monitoring information from CERN

These pages are written to display newest displays and monitoring information from the current datataking period of the LHC at CERN. It is intended for showcases. To use it, just open start in a browser.

Clone your own repository

Setup of Raspberry Pis as display stations

These steps lead you to a display station, based on a Raspberry Pie and a monitor.

• Setup Raspbian on your Raspberry Pi using either NOOBS or the manual installation image.

• Install chromium, a stable browser with full screen mode accessible from the command line. Also install the Microsoft ttf fonts.:

    sudo apt-get install chromium ttf-mscorefonts-installer
  

• Clone the repository in your home folder:

    git clone https://github.com/JoramBerger/cmstv.git
  

• To start the display on boot and prevent the screen saver from showing up, add these lines to /etc/xdg/lxsession/LXDE-pi/autostart. You may have to adapt the paths to the working copy of the cloned respository:

    @/home/pi/cmstv/mon.sh on
    @/home/pi/cmstv/start_cmstv.sh
  

  If the Raspberry Pi is not setup with NOOBS, the file is called /etc/xdg/lxsession/LXDE/autostart.

  If the screen is blank after waking up, try adding the following setting to /etc/rc.local.

    # disable console blanking for CMS-TV usage
    setterm -blank 0 -powersave off -powerdown 0 
  

• To show the display only on working days from 7 a.m. to 8 p.m., add these lines to crontab (crontab -e). Again check that the paths point to the checked out version of the cmstv repository. The start_cmstv.sh script will startup the browser in kiosk mode and check every 5 minutes if the browser is still running. Midori e.g. had some stability issues after running for a couple of days:

    0    7  *  *  1-5   /home/pi/cmstv/mon.sh on
    0   20  *  *  *     /home/pi/cmstv/mon.sh off
    */5  *  *  *  *     /home/pi/cmstv/start_cmstv.sh > /dev/null
  

Now it should be ready after reboot (no further interaction needed):

    sudo reboot
