Description
For the reliable and timely forecasts of dangerous conditions of Space Weather
world-wide networks of particle detectors are located at different latitudes,
longitudes and altitudes. To provide better integration of these networks the DAS
(Data Acquisition System) is facing a challenge to establish reliable data exchange
between multiple network nodes which are often located in hardly accessible locations
and operated by the different research groups. In this article we want to present DAS
for SEVAN (Space Environmental Viewing and Analysis Network) elaborated on the top of
free open-source technologies.
Our solution is organized as a distributed network of the uniform components
connected by standard interfaces. The main component is URCS (Unified Readout and
Control Server) which controls frontend electronics, obtains data and makes
preliminary analysis. The URCS operates fully autonomous. Essential characteristics
of software components and electronics are remotely controllable via dynamic web
interface, the data is stored locally for certain amount of time and distributed to
other nodes over web service interface on a request. To simplify data exchange with
collaborating groups we use extensible XML based format for the data dissemination.
The DAS at ASEC (Aragats Space Environmental Center) in Armenia is in operation from
November 2006. The reliability of the service was proved by continuous monitoring of
incident cosmic ray flux with 7 particle monitors located at 2000 and 3200 meters
above sea level on the distance of 40 and 60 km. from the data analysis servers in
main lab.
