MULTICHANNEL EQUIPMENT FOR SIGNAL ACQUISITION FROM VIBRATION TRANSDUCERS

摘要

The invention refers to a multichannel equipment for signal acquisition from vibration transducers, that can operate in field conditions also, and that can be used in seismic measurements, acoustics, voice processing, fault detection, etc. The advantages of this invention are: - fully programmable operating parameters that allow a high flexibility for the equipment ; - high signal-to-noise ratio and a high reliability; - fast transducer test feature; - low energy consumption. The multichannel equipment for signal acquisition from vibration transducers, according to the invention, includes one or more signal acquisition and analog-to-digital conversion modules, their transducers being tested with an appropriate device, all these subassemblies being supervised by one control and data transfer circuit connected to a computer internal bus.
