The system of streaming and analysis of signals from MEMS accelerometers

No. 87

301--312

In the article, a dedicated testing environment for MEMS acceleration sensors is shown. The system is able to collect data from multiple devices with different physical interfaces, send them through parallel streaming, archive, and analyze it. The architecture and operational algorithms of individual components, such as complex synchronization methods in the data streaming process is described. This data streaming is finally realized by Ethernet interface which becomes a bridge between the PC system running the dedicated application and the sensor board. In the last section of the article, quality indicators of acceleration sensors signals are presented. These indicators indicate primarily a useful signal to noise ratio with respect to the measurement resolution.
