Introduction

Idrophones

Preamplifier

Acquisition subsystem

Hydrophones raw data collector

Surface analyzer

Data transmission large band wifi link

Data transmission event notifier

Ground station

DIFI server

The DIFI server has address 192.168.253.87 on the internal department network.

It's services are remotely accessible, through port forwarding, from 130.251.168.253 by ports:

Ext.port Int.Port Service
4080 80 apache
4081 5901 vnc
4082 22 ssh
4083 443 https
4084 1194 openvpn
4085 5901 vnc
4086 3306 mysql
4087 873 rsync
4088 8888 proxy
4089 8080 calibre

Tasks of the DIFI server

  1. get analysis data from the on shore server
  2. get slow control data from the remote server
  3. transfer analysis data to the storage unit
  4. transfer slow control data to the storage unit
  5. transfer data to DIFI web server

Timing

Every action is done through crontab configuration 

*/5 * * * * /home/arion/arion-update-analysis
25 14 * * * /home/arion/arion-update-slowcontrol

to look at the runnning configuration, from arion user: 

crontab -l

to edit/update it: 

crontab -e

Data stream path

Data acquired from hydrophones to on buoy Carega or Sindaco are preamplified from PreAmplifier to and to the sampled from and .

Digital data are sent from and to the Ground station throug the wifi bridge and from internal and and external townet wireless IP67 5Ghz units.

The ImageMap extension is not installed.
