VibrationDetector¶
- class lsst.ts.mtrotator.VibrationDetector(period: float, max_times: int, frequency_range: list[float], snr: float, threshold: float, dt: float = 0.05)¶
Bases:
object
Vibration detector to monitor the low-frequency vibration.
- Parameters:
- period
float
Detection period of the low-frequency vibration in seconds. The data collected in this period will be used to do the fast Fourier transform (FFT).
- max_times
int
If the times of low-frequency vibration exceed this value contiguously, it will be identified as a vibration event.
- frequency_range
list
[float
] Frequency range [low, high] to detect in Hz.
- snr
float
Signal-to-noise ratio (SNR) of the low-frequency vibration (peak in the frequency diagram after FFT) to be identified as a vibration.
- threshold
float
Threshold to decide the post-processing data of rotator’s position can be used to do FFT or not (in degrees).
- dt
float
, optional Delta time between the data points in seconds. (the default is 0.05)
- period
Methods Summary
Check the vibration frequency in the detection range.
