| Zusammenfassung |
| Using commercial microwave link networks for precipitation estimation has become popular
in the last years. Acquiring the necessary data from the network operators is however still
difficult. Usually, data is provided to researches with large temporal delay and at irregular
basis.
Driven by the demand to facilitate this data accessibility, a custom acquisition software
for microwave links has been developed in joint cooperation with our industry partner
Ericsson. It is capable of recording data from a great number of microwave links
simultaneously and of forwarding the data instantaneously to a newly established
KIT-internal database. It makes use of the Simple Network Management Protocol (SNMP)
and collects the transmitter and receiver power levels via asynchronous SNMP
requests.
The software is currently in its first operational test phase, recording data from several
hundred Ericsson microwave links in southern Germany. Furthermore the software is used to
acquire data with 1 Hz temporal resolution from four microwave links operated by the skiing
resort in Garmisch-Partenkirchen.
For convenient accessibility of this amount of data we have developed a web
frontend for the emerging microwave link database. It provides dynamic real time
visualization and basic processing of the recorded transmitter and receiver power
levels.
Here we will present details of the custom data acquisition software with focus on the
design of the KIT microwave link database and on the specifically developed web frontend. |
