The core of the SMS / SAS is a Central Processing Unit (CPU) with a multi-channel digital recorder system rack mounted in a seismically and EMC safe cabinet together with an industrial PC and relevant peripherals.
Accelerometers, seismometers or complete seismic station packages, which are referred to as Detection / Recording Units (DRU's) are placed at remote locations that are connected to the CPU through shielded or fiber optic cables.
The system has been designed in a way that it is not bound to a single topology. There could be only the sensors or both sensors and data acquisition out in the field. Advantages of these topologies are briefly explained in the specifications section.
The system has a great modularity and flexibility so that an instrumentation upgrade is simplified and that as much as possible existing elements can be |
