Overview

  • GigE cameras work on the dedicated camera network, which is one of local networks under CDS network. The main software is managed on pylon-camera-server on LIGO Git and the binary package is available on LIGO's Debian repository via the apt-get command. A few camera servers belonging to both CDS and camera networks serves all camera images in the camera network to the client workstations in the CDS network. Old camera system called as camlan or camera-server is no longer updated for a long time. So it will be expired also in KAGRA, though the old one is still remaining.

How to Use

  • To show the display, open sitemap on any workstations (click medm icon on the desktop), and choose CAMERA.

  • You can record the movies from MEDM screen.

  • End-user Manual

How to add new cameras

  1. Setup camera IP address (blog)

  2. Install GigE camera
  3. Assign configuration file
  4. Start camera service
  5. Update medm screens

Configuration files

  • Configuration files are stored as K1-CAM-*.ini in /kagra/camera/pylon-camera-config/ (/kagra/camera/ instead for the old camlan system). A format of the configuration files are as follows. What we must edit are serial_number, overlay_text, multicast_addresses, channel_prefix and archive_file_name_prefix. Serial number can be checked on the camera body and camera name and multicast address must be decided as a unique value. 

    • serial_number=00000000
packet_size=8192
inter_packet_delay=50000
exposure_auto=0
exposure_time_raw=1000
gain_auto=0
gain_raw=100
timeout_ms=5000
width=640
height=480
framerate_numerator=25
framerate_denominator=1
format=GRAY8
overlay_text=OMC_TRANS
overlay_silent=false
multicast_address=239.192.0.x
multicast_port=65000
ttl_mc=64
channel_prefix=K1:CAM-OMC_TRANS_
calc_noise_floor=25
archive_interval_minutes=0
archive_folder_path_prefix=/kagra/camera/images/
archive_file_name_prefix=OMC_TRANS

Start (and manage) camera service

  • First, you need to decide which camera server (k1cam0, k1mca1, or k1cam2) to register the new camera with. Initial registration is done by logging into the camera server and executing the /kagra/camera/pylon-camera-service command (/kagra/camera/camera-service instead for the old camlan system). Following example is to register the OMC_TRANS camera on k1cam0. 

    • k1ctr> ssh k1cam0
k1cam0> /kagra/camera/pylon-camera-service enable OMC_TRANS

    pylon-camera-service command has following sub-commands. 

    • list                 : show registered cameras
enable <camera_name> : register cameras on the camera server
disable <camera_name>: unregister cameras on the camera server
start <camera_name>  : start camera process
stop <camera_name>   : stop camera process
restart <camera_name>: restart camera process
status <camera_name> : show the status of camera process
log <camera_name>    : show the log of camera process

    enable/disable can be executed only on the camera server and another sub-commands can be executed also on the CDS client workstations via /kagra/apps/camera/bin/camera-service-client.sh or the Shell Command block on the MEDM screens.

Update MEDM screens

  • MEDM screens are stored in /opt/rtcds/userapps/release/cds/common/medm. When the new cameras are added, K1IFO_CAM.adl and K1CAM_STATUS.adl must be updated. Camera interface screen is served as CUST_CAMERA_NEW.adl (CUST_CAMERA.adl instead for the old camlan system) with MEDM macros e.g. CAMERA=K1:CAM-OMC_TRANS and CONFIG=K1-CAM-OMC_TRANS.

How to recover

If GStreamer isn't started

  1. Disconnect the LAN cable once or Switch ON/OFF power supply from network switch
  2. Restart camera process 
    [controls@k1cam0 ~]$ ./camera-service restart CAMERA_NAME

How to ON/OFF power supply from camera switch

  1. SSH connect with dynamic forward 
    ssh -D 10000 k1cam0
  2. Open web browser on workstation with setting SOCKS proxy

    Preferences -> Network Settings -> "Manual proxy configuration" SOCKS Host:localhost, Port:10000

  3. Input IP address of network switch

  4. System -> PoE -> PoE Port Configuration

  5. Select the port and "disable" -> APPLY -> "Enable" -> APPLY

How to setup camera IP address
