5.3 The digital remote reading of our seismological school-observatory

Die Besonderheit unserer Seismographenstation ist die Möglichkeit, die Seismographen mit Hilfe eines Modems und eines Telnet-Clients "anzurufen". Special about our seismographic station is the possibility of "phoning" the seismographs with the help of a conventional modem and a simple terminal program:

Mit Hilfe dieser Funktion kann man sich die aufgezeichneten Signale der drei Seismographen aus den letzten vierzehn Tagen auf den PC nach Hause laden, und diese dann auswerten. so you can download the registered signals of the 3 seismographs in seven files concerning the last week on your PC at home and then evaluate them. One download takes about 7 min.

With the terminal-program and some self-developed software the members of our seismic-team can watch the signals generated by the three pendulums live, choose single traces and zoom them up to the size which is needed. The authorized operation crew can give the pendulums an impulse by touching a key and can so check if the pendulums can swing without hindrance.

The following illustration presents the layout of our seismological school-observatory as it was built by our former students Bernd Naeth (calibration and data analysis), Sebastian Schork (electronics and software) and Thomas Poschen (mechanical constructions).
